Long-term changes in graft height after maxillary sinus augmentation, onlay bone grafting, and combination of both techniques: a long-term retrospective cohort study

Schmitt C , Karasholi T, Lutz R, Wiltfang J, Neukam F-W, Schlegel KA. Long-term changes in graft height after maxillary sinus augmentation, onlay bone grafting, and combination of both techniques: a long-term retrospective cohort study. Clin. Oral Impl. Res. 00, 2012; 000000 doi: 10.1111/clr.12045



This investigation focused on long-term changes in graft height, implant survival rate, and peri-implant tissue conditions of dental implants placed in alveolar ridges after augmentation procedures with a follow-up of 10 years.

Material and methods

We conducted a retrospective cohort study with prospective long-term follow-up of 25 patients with edentulous severe atrophic maxillary situations who received a vertical augmentation procedure with autologous bone prior to implant placement. The participants were divided into three groups according to whether they underwent sinus elevation, onlay grafting, or a combination of both techniques. After a four-month healing period, 127 implants were inserted in the corresponding regions. Following a six-month healing period, the participants underwent prosthodontic rehabilitation, incorporating a fixed or removable implant denture. The cohort was clinically and radiographically followed up 1, 5, and 10 years after augmentation. The following parameters were measured: radiographic vertical bone changes, implant loss, peri-implant pocket depth (PD), width of keratinized mucosa (KM), sulcus fluid flow rate (SFFR), and the radiographic distance between the implant shoulder and the first visible bone-to-implant contact (DIB).


Seven implants were lost during the observation period, resulting in a cumulative 10-year survival rate of 94.48%. Significant bone loss occurred during the first 12 months, after which the resorption slowed down and bone height eventually stabilized. After 10 years, the total vertical bone loss was 27.51% after onlay grafting, 28.14% after sinus elevation, and 30.24% in the combination group, with no statistically significant between-group differences. Peri-implant follow-up examinations revealed a positive correlation between SFFR and PD, respectively, DIB, and a negative correlation between SFFR and KM.


The treatment method does not seem to impact vertical bone loss following augmentation using autologous grafts. This approach results in long-term stability of dental implants. A sufficient width of keratinized peri-implant mucosa is important to prevent peri-implant bone loss and inflammation.

Five-year results of a randomized controlled clinical trial comparing zirconia and titanium abutments supporting single-implant crowns in canine and posterior regions

Zembic A, Bösch A, Jung RE, Hämmerle CHF, Sailer I. Five-year results of a randomized controlled clinical trial comparing zirconia and titanium abutments supporting single-implant crowns in canine and posterior regions. Clin. Oral Impl. Res. 0, 2012; 17. doi: 10.1111/clr.12044Abstract


To test the survival rates, and the technical and biological complication rates of customized zirconia and titanium abutments 5 years after crown insertion.

Material and methods

Twenty-two patients with 40 single implants in maxillary and mandibular canine and posterior regions were included. The implant sites were randomly assigned to zirconia abutments supporting all-ceramic crowns or titanium abutments supporting metal-ceramic crowns. Clinical examinations were performed at baseline, and at 6, 12, 36 and 60 months of follow-up. The abutments and reconstructions were examined for technical and/or biological complications. Probing pocket depth (PPD), plaque control record (PCR) and Bleeding on Probing (BOP) were assessed at abutments (test) and analogous contralateral teeth (control). Radiographs of the implants revealed the bone level (BL) on mesial (mBL) and distal sides (dBL). Data were statistically analyzed with nonparametric mixed models provided by Brunner and Langer and STATA (P < 0.05).


Eighteen patients with 18 zirconia and 10 titanium abutments were available at a mean follow-up of 5.6 years (range 4.5–6.3 years). No abutment fracture or loss of a reconstruction occurred. Hence, the survival rate was 100% for both. Survival of implants supporting zirconia abutments was 88.9% and 90% for implants supporting titanium abutments. Chipping of the veneering ceramic occurred at three metal-ceramic crowns supported by titanium abutments. No significant differences were found at the zirconia and titanium abutments for PPD (meanPPDZrO23.3 ± 0.6 mm, mPPDTi3.6 ± 1.1 mm), PCR (mPCRZrO20.1 ± 0.3, mPCRTi0.3 ± 0.2) and BOP (mBOPZrO20.5 ± 0.3, mBOPTi0.6 ± 0.3). Moreover, the BL was similar at implants supporting zirconia and titanium abutments (mBLZrO21.8 ± 0.5, dBLZrO22.0 ± 0.8; mBLTi2.0 ± 0.8, dBLTi1.9 ± 0.8).


There were no statistically or clinically relevant differences between the 5-year survival rates, and the technical and biological complication rates of zirconia and titanium abutments in posterior regions.

Periodontists Explains the Periodontal Disease Connection

Research Indicates that Patients with Diabetes are at Higher Risk for Developing Infections, Including Periodontal Disease

Morganville, NJ (October 22, 2012) November is American Diabetes Month, and the New Jersey Society of Periodontists (NJSP) would like patients and caregivers alike to be aware of the link between periodontal disease, a chronic inflammatory disease of the gums, and diabetes.
“If you have diabetes, you are at higher risk for developing infections, including periodontal disease,” explains Dr. Scott Zirkin, President of the NJSP.  “These infections can impair the ability to process and/or utilize insulin, which may cause your diabetes to be more difficult to control and your infection to be more severe than a person with the disease.”
People with diabetes are more likely to have periodontal disease than people without diabetes, most likely because they are more susceptible to contracting infections. In fact, periodontal disease is often considered the sixth complication of diabetes, and those people who don't have their diabetes under control are especially at risk.*
A recent study in the Journal of Periodontology found that poorly-controlled type 2 diabetes patients are more likely to develop periodontal disease than well-controlled diabetes patients are. Moreover, research has emerged that suggests that the relationship between periodontal disease and diabetes goes both ways – periodontal disease may make it more difficult for people who have diabetes to control their blood sugar.

According to Gina Murdoch, Executive Director, American Diabetes Association, New Jersey Area, “We are very much aware of the link between periodontal disease and diabetes and understand the importance of the collaborative care of a periodontist and a physician.”

A study was published a few years back in the Journal of Periodontology that involved patients with both diabetes and periodontal disease. The study found that when their periodontal infections were treated, the management of their diabetes markedly improved. “The mouth/body connection is very strong and should not be underestimated by those living with diabetes or their caregivers,” says Dr. Zirkin.
According to Dr. Zirkin, severe periodontal disease can increase blood sugar, contributing to increased periods of time when the body functions with high blood sugar levels. This puts diabetics at a higher risk for diabetic complications. Thus, diabetics who have periodontal disease should be treated by a specialist to control and/or eliminate the periodontal infection.
Many other healthcare professionals from around New Jersey are also taking the opportunity during American Diabetes Month to educate local residents about diabetes, including Monmouth Medical Center in Long Branch.  "An important aspect of our diabetes self-management treatment plan is to educate patients about the many risks of poorly controlled diabetes, such as periodontal disease,” remarked Autumn Dempsey, RN, CDE, Program Coordinator for the Diabetes Education Center at Monmouth Medical Center.  “The Center for Diabetes Education at Monmouth Medical Center places a strong emphasis on good oral hygiene and urges patients to report any abnormal findings to their dentist. I encourage patients to use the many tools and resources provided by local healthcare facilities around New Jersey to reduce the chance of ever having to face diabetes-related complications." 
*Research documents available upon request.
About the New Jersey Society of Periodontists:
The New Jersey Society of Periodontists (NJSP) is an organization of New Jersey dentists who specialize in the art, science and practice of periodontics, including implants. The group is dedicated to advancing the knowledge base and understanding of periodontal diseases, as well as advancing ideas in treatment techniques in implantology. The NJSP seeks to explore and discuss problems of mutual interest with those in the practice of periodontics and implant dentistry. It supports the public, periodontists and all dental professionals involved in the oral care of patients of all ages. For more information, please visit

Carestream Dental Showcases New Solutions at the ADA Annual Session

New Products Offer Practitioners an Integrated Practice with
Advanced Imaging Capabilities and Streamlined Workflows
SAN FRANCISCO – Carestream Dental today launched the CS 8100 digital panoramic system at the American Dental Association (ADA) Annual Session, being held through Oct. 21 in San Francisco. Carestream Dental is also showcasing recent releases, including the CS 9300 Select, CS SoftDent v15.0 and CS PracticeWorks v7.5, which together put superior 3D imaging within reach of more practitioners and streamline practice workflows.

The new CS 8100 digital panoramic system features the latest imaging technology, offering practitioners a variety of imaging programs to obtain high-quality images effortlessly for improved diagnoses and treatments. With its compact footprint, the CS 8100 can be placed in even the smallest spaces.

Supporting the day-to-day panoramic imaging needs of practices, the CS 8100’s capabilities include panoramic imaging (for adults and pediatric patients) as well as segmented panoramic, TMJ and maxillary sinus imaging. The unit offers practitioners an intuitive user interface and computer control system that makes exams quick and simple. The system also comes with pre-set programs that minimize the setup required for exams, saving time and reducing operator errors.

In addition to its versatile imaging options, the CS 8100 also comes with exclusive 2D+ technology that enables practitioners to create slices at regular intervals along the jaw to focus on one area of interest and visualize more details than standard 2D images reveal. These images can help practitioners determine the location of supernumerary teeth, find impactions and apical lesions, or identify the root relationship to the inferior alveolar canal.

“Designed with practices’ workflows in mind, the CS 8100 makes panoramic imaging easier and faster for practitioners, with high-quality images accessible in seconds,” said Edward Shellard, D.M.D., chief marketing officer and director of business development for Carestream Dental. “This unit also sets new standards for ease of patient positioning, ensuring better image quality while offering greater patient comfort.”

For practices ready for 3D imaging, Carestream Dental’s new CS 9300 Select is tailored to meet any practice’s diagnostic needs and budget. A new addition to the CS 9300 family, the CS 9300 Select is complete with 3D cone beam computed tomography (CBCT) and 2D digital panoramic imaging in addition to an optional cephalometric modality. The differences between the CS 9300 Select and the original CS 9300 (launched in 2011) are the number and sizes of the 3D fields of view offered. The CS 9300 Select provides four selectable fields of view ranging from 5 cm x 5 cm to 10 cm x 10 cm. These fields of view are suitable for general practitioners and specialists placing implants or performing endodontic procedures, periodontal treatments and oral surgeries of the teeth and jaws.

As part of the company’s commitment to streamlining workflow with user-friendly solutions, Carestream Dental recently released CS SoftDent v15.0. This updated version features the new Scheduler, the most advanced scheduling software. The new Scheduler is designed to give practice administrators a better handle on the interruptive environment of the front desk. Intuitive and easy to use, the Scheduler’s multi-tasking capabilities let users easily resume partially completed tasks. Practitioners can add and schedule patients in a single, simple step with the advanced drag and drop functionality.

Another recent release, CS PracticeWorks v7.5 supports two new eServices that streamline reimbursement and patient registration. ePostings automatically notifies users when EOBs are received and then posts the payments directly to the appropriate patients within CS PracticeWorks. eForms allows patients to complete registration paperwork online at home or at a computer when they arrive for their appointments.

“CS SoftDent and CS PracticeWorks also integrate seamlessly with Carestream Dental’s imaging software,” Shellard said. “This integration means that once images are captured, they can be stored in patients’ electronic charts for quick and easy access.”

Carestream Dental invites all ADA Annual Session attendees to visit booth number 912 to get a hands-on demonstration of its suite of products during the show. For more information on Carestream Dental’s innovative solutions or to request a product demonstration, call (800) 944-6365 or visit

Immediate loading of four (all-on-4) post-extractive implants supporting mandibular cross-arch fixed prostheses: 18-month follow-up from a multicentre prospective cohort study.

Eur J Oral Implantol. 2012 Autumn;5(3):277-85.


Aim: To evaluate the outcome of immediately loaded mandibular cross-arch prostheses according to the 'all-on-4' concept supported by implants placed in fresh extraction sockets up to 18 months after loading. Materials and methods: In total, 47 patients with a mean age of 62.3 years (range 52 to 78) were rehabilitated with an immediately loaded fixed cross-arch prosthesis supported by four post-extractive implants. A total of 188 implants were inserted. Patients received a provisional fixed dental prosthesis with a metal framework within 48 hours after surgery and a permanent one 6 months later. The patients were evaluated clinically and radiographically at implant placement and at 6-, 12- and 18-month follow-up examinations. Results: At the 18-month follow-up, no implant failed and all restorations were stable. Peri-implant bone levels amounted to 0.31 ± 0.12 mm after 6 months, 0.58 ± 0.112 mm after 12 months and 0.7 ± 0.107 mm after 18 months. No significant differences in bone loss were found between axially placed and tilted implants at the 6-month (0.06 mm; P = 0.115), the 12-month (0.12 mm; P = 0.062) and the 18-month follow-up (0.08 mm; P = 0.146). Three patients had a fracture of the provisional restoration, but all of the definitive prostheses remained stable throughout the study period without any complications. Conclusions: Within the limits of this study, it can be suggested that immediately loaded mandibular cross-arch fixed dental prostheses can be supported by four post-extractive implants, however larger and longer follow-ups are needed.

Soft tissue management for dental implants: what are the most effective techniques? A Cochrane systematic review.

Eur J Oral Implantol. 2012 Autumn;5(3):221-38


This review is based on a Cochrane systematic review entitled 'Interventions for replacing missing teeth: management of soft tissues for dental implants' published in The Cochrane Library (see http:// for information). Cochrane systematic reviews are regularly updated to include new research, and in response to comments and criticisms from readers. If you wish to comment on this review, please send your comments to the Cochrane website or to Marco Esposito. The Cochrane Library should be consulted for the most recent version of the review. The results of a Cochrane review can be interpreted differently, depending on people's perspectives and circumstances. Please consider the conclusions presented carefully. They are the opinions of the review authors, and are not necessarily shared by the Cochrane Collaboration. Purpose: To evaluate whether flapless procedures are beneficial for patients and which is the ideal flap design, whether soft tissue correction/augmentation techniques are beneficial for patients and which are the best techniques, whether techniques to increase the peri-implant keratinised mucosa are beneficial for patients and which are the best techniques, and which are the best suturing techniques/ materials. Materials and methods: The Cochrane Oral Health Group's Trials Register, CENTRAL, MEDLINE and EMBASE were searched up to the 9th of June 2011 for randomised controlled trials (RCTs) of rootform osseointegrated dental implants, with a follow-up of at least 6 months after function, comparing various techniques to handle soft tissues in relation to dental implants. Primary outcome measures were prosthetic failures, implant failures and biological complications. Screening of eligible studies, assessment of the methodological quality of the trials and data extraction were conducted at least in duplicate and independently by two or more review authors. The statistical unit was the patient and not the prosthesis, the procedure or the implant. Results were expressed using risk ratios for dichotomous outcomes and mean differences for continuous outcomes with 95% confidence intervals (CI). Results: Seventeen potentially eligible RCTs were identified but only six trials with 138 patients in total could be included. The following techniques were compared in the six included studies: flapless placement of dental implants versus conventional flap elevation (2 trials, 56 patients), crestal versus vestibular incisions (1 trial, 10 patients), Erbium:YAG laser versus flap elevation at the second-stage surgery for implant exposure (1 trial, 20 patients), whether a connective tissue graft at implant placement could be effective in augmenting peri-implant tissues (1 split-mouth trial, 10 patients), and autograft versus an animal-derived collagen matrix to increase the height of the keratinised mucosa (1 trial, 40 patients). On a patient rather than per implant basis, implants placed with a flapless technique and implant exposures performed with laser lead to statistically significantly less postoperative pain than flap elevation. Sites augmented with soft tissue connective grafts had better aesthetics and thicker tissues. Both palatal autografts or the use of a porcine-derived collagen matrix are effective in increasing the height of keratinised mucosa at the cost of a 0.5 mm recession of peri-implant soft tissues. There were no other statistically significant differences for any of the remaining analyses. Conclusions: There is limited weak evidence suggesting that flapless implant placement is feasible and has been shown to reduce patient postoperative discomfort in adequately selected patients, that augmentation at implant sites with soft tissue grafts is effective in increasing soft tissue thickness and improving aesthetics, and that one technique to increase the height of keratinised mucosa using autografts or an animal-derived collagen matrix was able to achieve its goal but at the cost of a worsened aesthetic outcome (0.5 mm of recession). There is insufficient reliable evidence to provide recommendations on which is the ideal flap design, the best soft tissue augmentation technique, whether techniques to increase the width of keratinised/attached mucosa are beneficial to patients or not, and which are the best incision/suture techniques/materials. Properly designed and conducted RCTs, with at least 6 months of follow-up, are needed to provide reliable answers to these questions.

UCLA Dentistry receives major grant to develop saliva test to predict onset of PTSD

Each year, more than a million Americans are at-risk of developing serious mental health problems after experiencing a terrifying event or serious physical injury. Once manifested, these psychiatric illnesses, such as post-traumatic stress disorder and depression, can be extremely crippling and difficult to treat and are a leading cause of disability in civilian, military and minority populations.
Recognizing these emerging disorders early on provides health care professionals the best opportunity for preventive interventions.
Now, a team of researchers, led by Dr. Vivek Shetty, a professor at the UCLA School of Dentistry, has received a $3.8 million research grant to develop a salivary-biomarker approach for identifying individuals at future risk of developing post-traumatic stress disorder and depression following a traumatic event.
Co-funded by the National Institute of Dental and Craniofacial Research and the National Institutes of Health's Office of Behavioral and Social Sciences Research, the study seeks to develop a panel of salivary stress biomarkers that will allow early recognition of emerging mental health disorders and permit preemptive psychological care.
"Current assessment strategies rely on subjective reports of symptoms by trauma survivors," Shetty said. "The symptom-based nature of psychological assessments presents significant challenges for trauma-care specialists attempting to differentiate between temporary distress and the early stages of mental health illnesses.
"Moreover," he added, "the time and resource constraints of the acute-care setting do not allow for the structured screening required for psychological assessments. If successful, our salivary stress biomarker panel will allow the development of practical decision-aid tools to complement subjective clinical evaluation and allow timely referrals of 'at-risk' individuals."
For the new five-year study, Shetty and his colleagues will repeatedly conduct psychological assessments and obtain corresponding saliva samples over a six-month period among a group of 600 individuals who have recently experienced a serious physical injury or sexual assault.
The team will use sophisticated analytical techniques to determine the levels of the individual salivary biomarkers at different points over the six months and to compare the biomarker patterns of individuals who subsequently develop PTSD and/or depression with those who do not.
The association of the biomarkers with mental disease would be used to develop mathematical models that utilize early stress biomarker levels to predict later development of traumatic psychopathology.
"Utilizing easily accessible saliva for evaluating stress reactions would allow front-line care providers to become more involved and proactive in the management of post-traumatic stress disorders, moving the focus away from treatment of unmanageable, late-stage conditions toward early identification and targeted interventions of vulnerable individuals," said Shetty.
"Enabling health care providers to objectively and readily assess the risk for future psychological problems will set the stage for integrated post-trauma care that provides for essential and tailored mental health interventions in trauma care centers, as well as timely referrals for psychological after-care."
The current research study builds on and complements Shetty's ongoing development of mobile devices for point-of-care assessment and management of post-traumatic stress disorders using salivary diagnostics — a program funded through NIH's Transdisciplinary Gene and Environment Initiative.
"Beyond the civilian population, post-traumatic mental health disorders are a significant problem for our military," said Dr. No-Hee Park, dean of the School of Dentistry. "The scope of the mental health problem is increasingly manifest as thousands of soldiers are coming back from Iraq and Afghanistan. This grant allows Dr. Shetty to focus the skills and abilities of his team to help solve a very serious problem with advanced technology in the cutting-edge area of salivary diagnostics. I am hopeful that the results of this research will inform mental health efforts not only in civilian populations but also in military settings.
"Faculty from the UCLA School of Dentistry," Park added, "have been at the forefront of the emerging field of salivary diagnostics in recent years, conducting groundbreaking research on the use of saliva as a diagnostic tool for the detection of oral cancer, early-stage pancreatic cancer, Sjogren's syndrome and a variety of other maladies."
Shetty's collaborators on the project include Dr. David Elashoff of the UCLA departments of biostatistics and internal medicine; Dr. Theodore Robles of the UCLA Department of Psychology; Dr. Debra Murphy of the UCLA Department of Psychiatry and Biobehavioral Sciences; Dr. Grant Marshall of the RAND Corp.; Dr. Michael Lynes of the University of Connecticut; and Drs. Demetriades and Yamashita at the trauma center at Los Angeles CountyUSC Medical Center.

The UCLA School of Dentistry is dedicated to improving the oral health of the people of California, the nation and the world through its teaching, research, patient care and public service initiatives. The school provides education and training programs that develop leaders in dental education, research, the profession and the community; conducts research programs that generate new knowledge, promote oral health and investigate the cause, prevention, diagnosis and treatment of oral disease in an individualized disease-prevention and management model; and delivers patient-centered oral health care to the community and the state.

New Evaluation Method For Toothpaste

11 Oct 2012 

There are various types of toothpaste available on the market. They come as pastes and gels, there are some that guard against tooth decay or protect teeth from acid attack, others that are designed for sensitive teeth. But which toothpastes clean well? Which preserve the tooth enamel? A new evaluation method sheds light on the subject.

Everyone wants to have beautiful teeth. After all, a perfect set of teeth symbolizes health and youthfulness, and can even influence career prospects. If having pristine teeth calls for thorough oral hygiene, then how well or badly does a given toothpaste clean? How effective is it? What should it contain in order not to damage the structure of the teeth? Such questions are primarily of interest to manufacturers of dental hygiene products, and answers are being delivered by researchers from the Fraunhofer Institute for Mechanics of Materials IWM in Halle. Through close collaboration with the Microtribology Centre µTC in Karlsruhe they have developed a new process for testing the abrasive effect of toothpastes, allowing this 'abrasivity', as experts call it, to be compared and evaluated in the lab.

Dangerous abrasive effect

Cleaning particles are an important component of toothpastes. These abrasives, as they are known, mechanically remove dental plaque. Nevertheless, the paste should not be too strongly abrasive. Over the years the abrasion can cause damage to the tooth enamel, which does not regenerate itself. This damage is more visible and pronounced in the soft dentin. The German Dental Association recommends that people choose less abrasive toothpaste if the necks of their teeth are exposed.

The abrasive effect of a particular toothpaste on tooth dentin depends on the hardness, amount and particle size of the abrasive additives it contains, such as silica or alumina. Abrasivity is measured as the RDA value (radioactive dentin abrasion), ranging from 30 to over 200. This value is determined via a complex process that involves testers brushing over radioactively marked dentin samples. The abraded material is then measured via the resultant radiation intensity of the toothpaste slurry. Not all experts agree on the validity of RDA values, as test results have been known to vary partly from lab to lab.

Determining abrasion rates with microtribological tests

The researchers at the IWM have chosen an alternative method to this radiotracer system. "Our new approach enables us to determine realistic abrasion rates and characterize the interaction between brush, enamel and toothpaste. What's more, our tests are less laborious than the time-intensive radiotracer procedures carried out by only a handful of laboratories worldwide", says Dr. Andreas Kiesow, team leader at the IWM. The scientist and his team have successfully managed to determine the abrasion of various toothpastes on a microscopic scale and to measure the friction values using microtribological experiments. "Until now, tribological values such as friction coefficient, did not exist" says Kiesow.

The researchers use human teeth as well as different toothpastes made by industrial partners for their experiments. These toothpastes were diluted with water and saliva in order to create a solution whose consistency corresponds to the mixture of toothpaste and saliva that is present when people brush their teeth. The friction and wear tests were each carried out with a single bristle - referred to as a monofilament. This is mounted in specialized tribological instruments, a microtribometer and a nanoindenter, and moved over the sample in both straight and circular motions, in the latter case up to 8000 times. Highly sensitive instruments then measure the depth of the resultant marks left on the surface of the tooth. "Our findings reveal that the RDA value of toothpastes correlates with the depth of abrasion; the higher the value, the greater the abrasion. By analyzing the friction value we also identified a clear relationship between the friction behaviors of the bristle on the dental enamel and the abrasiveness of the toothpaste", sums up Kiesow. The new process allows the researchers to not only characterize the abrasion more quickly and simply, but also to describe how different geometries of toothbrush filaments act upon the surface of the tooth and how the bristle shape should ideally be designed. The experts at IWM can use their know how to support manufacturers of dental hygiene with product development. At the end of the day it is the consumer who benefits most.

Swapping Germs: Bad for You and Dog

Here is an interesting article on periodontal pathogens in dogs and their owners.  It won't change my interaction with my dog but it is an interesting read. MJ

Dog owners and their pets may exchange harmful mouth bacteria that can cause gum disease and tooth decay in both humans and canines, according to a report in Archives of Oral Biology. Previous research has shown people can transmit oral bacteria to children through close daily contact. But few studies have looked at the bacteria exchanged between people and their pets.

Zirconia crowns and wear.

A discussion on the Internet Dental Forum brought up the discussion of the wear of opposing teeth when placing a Zirconia crown.  I place a lot of Zirconia crowns in the 1st and 2nd molar regions because of their strength and better (not great) esthetics compared to gold. 

So here is a wear study to backup the claim MJ

J Adv Prosthodont. 2010 Sep;2(3):111-5. Epub 2010 Sep 30.

A study on the in-vitro wear of the natural tooth structure by opposing zirconia or dental porcelain.


Advanced Prosthodontics, Graduate School of Clinical Dentistry, Korea University, Seoul, Korea.



This study was conducted to evaluate clinical validity of a zirconia full-coverage crown by comparing zirconia's wear capacity over antagonistic teeth with that of feldspathic dental porcelain.


THE SUBJECT GROUPS WERE DIVIDED INTO THREE GROUPS: the polished feldspathic dental porcelain group (Group 1), the polished zirconia group (Group 2), and the polished zirconia with glazing group (Group 3). Twenty specimens were prepared from each group. Each procedure such as plasticity, condensation, and glazing was conducted according to the manufacturer's manual. A wear test was conducted with 240,000 chewing cycles using a dual-axis chewing simulator. The degree of wear of the antagonistic teeth was calculated by measuring the volume loss using a three-dimensional profiling system and ANSUR 3D software. The statistical significance of the measured degree of wear was tested with a significant level of 5% using one-way ANOVA and the Tukey test.


The degrees of wear of the antagonistic teeth were 0.119 ± 0.059 mm(3) in Group 1, 0.078 ± 0.063 mm(3) in Group 3, and 0.031 ± 0.033 mm(3) in Group 2. Statistical significance was found between Group 1 and Groups 2 and between Group 2 and 3, whereas no statistical significance was found between Group 1 and Group 3.


Despite the limitations of this study on the evaluation of antagonistic teeth wear, the degree of antagonistic tooth wear was less in zirconia than feldspathic dental porcelain, representing that the zirconia may be more beneficial in terms of antagonistic tooth wear.

Properties of dental resins submitted to pH catalysed hydrolysis

Available online 26 September 2012



This study evaluated the surface microhardness (SM) and roughness (SR) alterations of dental resins submitted to pH catalysed degradation regimens.


Thirty discs of each TPH Spectrum (Dentsply), Z100 (3M-ESPE), or an unfilled experimental bis-GMA/TEGDMA resin were fabricated, totaling 90 specimens. Each specimen was polymerized for 40 s, finished, polished, and individually stored in deionized water at 37 °C for 7 days. Specimens were randomly assigned to the following pH solutions: 1.0, 6.9 or 13, and for SM or SR evaluations (n = 5). Baseline Knoop-hardness of each specimen was obtained by the arithmetic mean of five random micro-indentations. For SR, mean baseline values were obtained by five random surface tracings (Ra). Specimens were then soaked in one of the following storage media at 37 °C: (1) 0.1 M, pH 1.0 HCl, (2) 0.1 N, pH 13.0 NaOCl, and (3) deionized water (pH 6.9). Solutions were replaced daily. Repeated SM and SR measurements were performed at the 3-, 7- and 14-day storage time intervals. For each test and resin, data were analysed by two-way ANOVA followed by Tukey's test (α = 0.05).


There was significant decrease in SM and increase in SR values of composites after storage in alkaline medium. TPH and Z100 presented similar behaviour for SM and SR after immersion in the different media, whereas unfilled resin values showed no significant change.


Hydrolytic degradation of resin composites seems to begin with the silanized inorganic particles and therefore depend on their composition.


To accelerate composite hydrolysis and produce quick in vitro microstructural damage, alkaline medium appears to be more suitable than acidic medium. Contemporary resin composite properties seem to withstand neutral and acidic oral environments tolerably well.

Increased plasma and salivary cortisol levels in patients with oral cancer and their association with clinical stage

J Clin Pathol 65:934-939 doi:10.1136/jclinpath-2012-200695


Objectives Dysregulation of the hypothalamus–pituitary–adrenal axis has been observed in patients with cancer. This cross-sectional study investigated whether patients with oral and oropharyngeal squamous cell carcinoma (SCC) show changes in cortisol levels in saliva and plasma compared with three control groups, and evaluated its correlation with clinicopathological data.
Methods Salivary and plasma cortisol levels of 34 patients with oral SCC were compared with hormonal levels of 17 oropharyngeal SCC patients, 17 oral leukoplakia patients, 27 smokers and/or drinkers and 25 healthy volunteers. Multivariate analysis was used to evaluate the impact of clinical variables on the cortisol levels.

DentalEZ Group to Introduce RAMVAC® Osprey Compressors at ADA 2012

Malvern, PA (October 8, 2012) DentalEZ® Group, a supplier of innovative products and services for dental health professionals worldwide, will officially unveil its new RAMVAC® Osprey family of dental air compressors during the 2012 American Dental Association Meeting on October 18-20 at booth #1908. 

For any dental practice looking to increase productivity and decrease downtime servicing their utility room equipment, the RAMVAC Osprey Compressor is the #1 choice. The remarkable, quiet design of the new Osprey compressors provides clean, dry, oil-free air in even the busiest dental office environment. The unique blueprint of the new compressors has many inherent advantages over earlier compressors. 

With high quality air at a maximum pressure of 115 psi, the Osprey compressor operates at 100% duty cycle during peak operation times. The rocking piston design technology provides quiet operation while still producing more peak airflow than other compressors on the market. This is especially important with more dental equipment than ever requiring quality compressed air for optimal operation.

“Worry-free utility room equipment is the starting point for an efficient dental practice,” remarked Ryon Waddington, Senior Product Manager. “RAMVAC compressors provide the dental professional freedom to focus on patient care, not equipment repair. We are extremely confident that the Osprey will become a utility room staple of the dental practice.” 

Osprey compressors are available in either Basic or Smart control platforms:

• Basic control platform - employs a traditional pressure switch and contactor arrangement to control the cycling of the compressor heads. Basic controls are equipped with switches to isolate or turn off individual heads (as required by NFPA99C) and hour meters.
• Smart control platform (C2 Control) - utilizes a more modern digital technology, utilizing a pressure transducer and solid state relays to control cycling. Smart controls also feature head isolation, current sensing (head amperage draw), maintenance reminders, fault notifications, and average drain and recharge times.

The dual column desiccant dryer provides 100% continuous supply of dry clean free air. While one column is drying, the other is in operation.  Moreover, desiccant cartridges are replaced right in the office.

The Osprey is offered in the following user sizes:

  • OSP22 1-3 User - single head, 2 hp, and 12 gallon tank
  • OSP13 3-4 User - 115 volt option, dual head, 2½ total hp, and 12 gallon tank
