Carestream Health’s Shipments of Innovative Wireless DRX Detector Reach New High

Affordable Digital X-ray Systems Provide Immediate Images in Diverse Patient Care Settings

ROCHESTER, N.Y., Jan. 24 — High-quality, affordable digital X-ray images in about four seconds— with wireless communication that allows clinicians to immediately view images from any location. This compelling workflow is the driving force behind the rapid adoption of Carestream Health’s flexible, wireless DRX detectors.

The company has shipped more than 3,300 DRX detectors since launching the CARESTREAM DRX-1, the radiology profession’s first wireless, cassette-size X-ray detector. Carestream’s comprehensive product portfolio serves diverse applications—from surgical suites, ER/ICU and radiology departments to clinics, imaging centers, nursing homes and field military hospitals.

The company’s family of DRX-based systems help streamline workflow, improve productivity and enhance patient care in both in-room and mobile environments. For example, these lightweight, digital X-ray detectors can be used in general radiology exam rooms and mobile units during the day, and are easily moved to serve the emergency department at night.

Carestream’s DRX-based portfolio includes the CARESTREAM DRX-1 System, CARESTREAM DRX-Mobile Retrofit kit, CARESTREAM DRX-Evolution suite, CARESTREAM DRX-Transportable System and CARESTREAM DRX-Ascend System.

The DRX family also includes a second detector, the cesium iodide-based CARESTREAM DRX-1C, that offers exceptional image quality and improved DQE (detective quantum efficiency). The DRX-1C detector’s superior image quality makes it an ideal fit for orthopedic, trauma, pediatric and other specialty environments, in addition to general radiography exams.

Patient care in ED, ICU, pediatric ICU and other environments is enhanced with an innovative Tube and Line Visualization feature that uses a single exposure to display an enhanced companion image with more precise visualization of lines and tubes, which are typically difficult to view. Allowing physicians to verify correct placements in seconds helps improve patient care and comfort, while simultaneously reducing the need for multiple imaging exams.

Carestream’s DRX detectors work with existing x-ray equipment and can easily be moved to any DRX room or mobile DRX system, a feature the company refers to as the “X-Factor.” Healthcare providers can also move the detectors to new imaging systems when existing x-ray systems become outdated.

Antioxidants Counteract Nicotine and Promote Migration via RacGTP in Oral Fibroblast Cells

Journal of Periodontology
2010, Vol. 81, No. 11, Pages 1675-1690 , DOI 10.1902/jop.2010.100187

Symone M. San Miguel,* Lynne A. Opperman,* Edward P. Allen, Jan Zielinski, and Kathy K.H. Svoboda*
indicates supplementary video in the online Journal of Periodontology.

Background: Smoking is associated with an increased risk of oral health and dental problems. The aim of this study is to address the hypothesis that nicotine impairs wound healing by increasing reactive oxygen species and inhibiting cell migration, and antioxidants (AOs) may counteract nicotine effects.
Methods: Primary human gingival fibroblasts (HGFs) and human periodontal ligament (HPDL) fibroblasts were grown to confluence, pretreated with 6 mM nicotine for 2 hours, and treated with AOs in the presence of nicotine. The pure AO compounds ferulic acid (F), phloretin (P), tetrahydrocurcuminoid Cockroft Gault (T), and resveratrol (R) were tested in single, double, or triple combinations (10−5 M). The migratory behavior at a scratch-wound edge was recorded every 15 minutes for 10 hours by using live-cell imaging. The active form of the Rho-associated protein (Rac) and guanosine triphosphate (GTP) (RacGTP) was immunolabeled and analyzed using confocal microscopy.
Results: Combinations of double and triple AOs had a greater effect than single AOs on migration rates and Rac activation. The triple combinations PFR and RFT clearly and unambiguously counteracted the effects of nicotine and significantly increased migration rates in HGF and HPDL fibroblast.
Conclusions: Treatment with AO combinations clearly counteracted the effects of nicotine by restoring and increasing cell-migration rates. We found the combination of PFR was the most effective in HGFs, whereas, RFT was the most effective combination in HPDL fibroblast. These results clearly demonstrate that PF, RFT, and PFR counteract the negative effects of nicotine on cultured oral fibroblasts via the RacGTP signal-transduction pathway.

Resistance to compression of weakened roots subjected to different root reconstruction protocols

Journal of Applied Oral Science

Print version ISSN 1678-7757

J. Appl. Oral Sci. vol.19 no.6 Bauru Nov./Dec. 2011

OBJECTIVE: This study evaluated, in vitro, the fracture resistance of human non-vital teeth restored with different reconstruction protocols.
MATERIAL AND METHODS: Forty human anterior roots of similar shape and dimensions were assigned to four groups (n=10), according to the root reconstruction protocol: Group I (control): non-weakened roots with glass fiber post; Group II: roots with composite resin by incremental technique and glass fiber post; Group III: roots with accessory glass fiber posts and glass fiber post; and Group IV: roots with anatomic glass fiber post technique. Following post cementation and core reconstruction, the roots were embedded in chemically activated acrylic resin and submitted to fracture resistance testing, with a compressive load at an angle of 45º in relation to the long axis of the root at a speed of 0.5 mm/min until fracture. All data were statistically analyzed with bilateral Dunnett's test (
RESULTS: Group I presented higher mean values of fracture resistance when compared with the three experimental groups, which, in turn, presented similar resistance to fracture among each other. None of the techniques of root reconstruction with intraradicular posts improved root strength, and the incremental technique was suggested as being the most recommendable, since the type of fracture that occurred allowed the remaining dental structure to be repaired.
CONCLUSION: The results of this in vitro study suggest that the healthy remaining radicular dentin is more important to increase fracture resistance than the root reconstruction protocol.

Differences Between Reported And Actual Restored Caries Lesion Depths: Results From The Dental PBRN




The objectives of this research were to (1) quantify the discordance between the caries lesion depth at which dentists restored initial lesions during a clinical study (“actual depth”) and the lesion depth that they reported during a hypothetical clinical scenario (“reported depth”); (2) test the hypothesis that certain practitioner, practice, patient, and caries lesion characteristics are significantly associated with this discordance.


: Practitioner-investigators who perform restorative dentistry in their practices completed an enrollment questionnaire and participated in two consecutive studies on caries diagnosis and treatment. The first study was a survey asking about caries treatment. The second study collected data on restorations placed in routine clinical practice due to caries in patients over 19 years of age on occlusal surfaces only or proximal surfaces only. We report results on 2691 restorations placed by 205 dentists in 1930 patients with complete data.


: Discordance between actual depth and reported depth occurred in only about 2% of the restorations done due to proximal caries, but about 49% of the restorations done due to occlusal caries. Practice type, restorative material used and the diagnostic methods used were significantly associated with discordance.


: Dentists frequently restored occlusal caries at a shallower depth as compared to their reported depth, but the discordance was very small for proximal lesions. Discordance for occlusal caries was more common when radiographs were not taken or if a resin restoration was placed.

Association between chronic periodontitis and rheumatoid arthritis: a hospital-based case–control study

DOI: 10.1007/s00296-011-2284-1


Rheumatoid arthritis (RA) and chronic periodontitis are the most common chronic inflammatory diseases with remarkable pathological and clinical similarities. A lot of similarities exist between RA and periodontitis at cellular and molecular levels. The relationship between these two chronic inflammatory diseases is still unclear. This case–control study was undertaken to determine the possible association between chronic inflammatory diseases like RA and periodontitis. The case group consisted of 100 patients attending the Rheumatology clinic who have rheumatoid arthritis (RA group). Age- and gender-matched 112 patients without RA attending the Outpatient wing of Department of General Medicine formed the control group (NRA group). The number of missing teeth, gingival index (GI), oral hygiene index-simplified (OHI-S), probing pocket depth (PPD) and clinical attachment levels (CAL) were evaluated in both the groups. Rheumatoid disease activity was assessed by DAS-28 score system. Systemic markers of inflammation like erythrocytic sedimentation rate (ESR) and serum levels of C-reactive protein (CRP) were assessed. There was a statistically significant difference in GI, OHI-S, PPD, CAL, ESR and CRP levels between cases (RA group) and controls (NRA group) (P < 0.05). Among subjects with RA, there was no association between the rheumatoid disease activity and the severity of periodontal disease. The occurrence and severity of periodontitis was found to be higher in RA subjects as compared to subjects without RA, suggesting a positive relation between these two chronic inflammatory diseases.

Dental staff doses with handheld dental intraoral x-ray units.

Health Phys. 2012 Feb;102(2):137-42.


A handheld portable dental intraoral x-ray system is available in the United States and elsewhere. The system is designed to minimize the user's radiation dose. It includes specially designed shielding of the x-ray tube housing and an integral radiation shield to minimize backscatter. Personnel radiation dose records were obtained from 18 dental facilities using both the handheld system and a wall mounted dental x-ray system, providing 661 individual dose measurements. Dental staff doses were also compared for the handheld and conventional systems using both film and digital imaging for the same facilities and staff members. The results indicate that the doses for the handheld systems are significantly less than for wall-mounted systems. The average monthly dose for the handheld systems was 0.28 μSv vs. 7.86 μSv (deep dose equivalent) for the wall-mounted systems, a difference that is statistically significant at the p = 0.01 level. Consequently, there should be no concern about the use of this handheld dental intraoral x-ray system. Additional shielding efforts, (e.g., wearing a lead apron) will not provide significant benefit nor reduce staff radiation dose.

Houston, Texas—January 11, 2012—ClearCorrect™, the manufacturer of orthodontic clear aligners (named America’s fastest-growing health company for 2011 by Inc. magazine), recently launched Phase Out™, a new project focused on making a difference.
In a post on the company’s blog, ClearCorrect CEO, Jarrett Pumphrey, said, “Five years ago, we started ClearCorrect out of a passion to help. Doctors had no choice in clear aligners, and we wanted to change that. Since then, we've remained focused on changing the clear aligner industry. Well, now our ambitions have grown. I’m very happy to announce Phase Out, a new ClearCorrect project we’re kicking off this year. The purpose of the project: To change the world.”
ClearCorrect’s unique phase-based approach to clear aligners is at the heart of the project: Every ClearCorrect case includes a certain number of phases (a phase is a box with 4 sets of clear aligners).  More often than not, a few phases are left over at the end of treatment. Starting January 1, 2012, for each leftover phase, $20 will go toward phasing out life-impacting issues for people in need. 
ClearCorrect is partnering with charity: water to launch the first of several Phase Out initiatives envisioned for the project:  phase out unsafe drinking water.
“It’s unbelievable that nearly a billion people on the planet still don’t have access to something so basic as clean drinking water,” says Pumphrey. “charity: water is an incredible organization working to change that. They have a big job to do, and we want to help them.”
Through Phase Out, every time a phase is left over at the end of ClearCorrect treatment, $20 will go toward building wells and other water projects in developing nations with charity: water. One phase = one person with access to clean, safe drinking water.
To learn more about this project or get involved, visit: http://clearcorrect.com/phaseout.
About ClearCorrect

About charity: water
charity: water is a non-profit organization bringing clean, safe drinking water to people in developing nations. 100%of public donations go directly to fund sustainable water solutions in areas of greatest need. Unsafe water and lack of basic sanitation cause 80 percent of diseases and kill more people every year than all forms of violence, including war. Children are especially vulnerable, as their bodies aren't strong enough to fight diarrhea, dysentery and other illnesses. Just $20 can give one person access to a clean water project.  Learn more at: www.charitywater.org.

Immediate Postextractive Dental Implant Placement with Immediate Loading on Four Implants for Mandibular-Full-Arch Rehabilitation: A Retrospective Analysis

Mozzati, M., Arata, V., Gallesio, G., Mussano, F. and Carossa, S. (2012), Immediate Postextractive Dental Implant Placement with Immediate Loading on Four Implants for Mandibular-Full-Arch Rehabilitation: A Retrospective Analysis. Clinical Implant Dentistry and Related Research. doi: 10.1111/j.1708-8208.2011.00412.x


Background: To date, only few studies have reported on the clinical outcomes of immediate postextraction implant placement and immediate loading.
Purpose: The purpose of this retrospective study was to report the results of immediately loading four implants placed in fresh extraction sockets in the mandible after a follow-up of 24 months.
Materials and Methods: Between January 2001 and January 2009, 50 patients (28 women and 22 men, average age 54 years), had 347 teeth extracted and a total of 200 dental implants placed in the mandible. The patients received a provisional fixed bridge the same day and a permanent one 3 months later. Clinical checkups were performed after 1, 2, 3, 6, 12, and 24 months. Marginal bone measurements were made in intraoral radiographs taken 1 day after surgery and after 1 year. A questionnaire was used to evaluate self-perceived factors related to comfort, aesthetics, and function.
Results: All bridges were stable and no implant failures were recorded during the follow-up, giving a survival rate of 100%, at 2 years. The marginal bone loss amounted to 1.33 ± 0.36 mm after 1 year and 1.48 ± 0.39 mm after 2 years. Ten patients showed prosthetic complications with the provisional bridge, but all the definitive prostheses remained stable throughout the study period without any complications. The patients reported satisfaction with the treatment.
Conclusions: The present retrospective study showed that immediate loading of four implants immediately placed in extraction sockets is a valid treatment modality for the totally edentulous mandible.

Reasons for replacement of restorations: dentists' perceptions.

Acta Odontol Scand. 2012 Jan 3. [Epub ahead of print]


Institute of Dentistry, Department of Oral Public Health, University of Helsinki , Helsinki , Finland.


Abstract Objective. This study aimed at evaluating dentists' perceived reasons for replacement of restorations and ascertaining the differences arising from dentists' gender, time since graduation and working sector (salaried vs private). Materials and methods. A postal questionnaire was sent to a total of 592 working-age general dental practitioners in Finland, 57% (n = 339) responded. The dentists were asked to rank in order of priority the six most common reasons for replacement of composite in the incisors and posterior teeth and amalgam in the posterior tooth from a list of 12 reasons. Ranking order 1 was worth six points and order 6 one point; the non-ranked reasons were equal to zero. Differences in the means of the summed scores of caries-related (RC), fracture- and failure-related (RF) and miscellaneous (RO) groups were evaluated by ANOVA. The level of significance was set at p = 0.05. Results. For each of three restorations, the RF group comprised 48-56% of the sum-scores. Of the single reasons, secondary caries predominated (20-24%). For composite restorations in the incisors, the mean sum-score of the RO group was greater for private-sector dentists (p = 0.04). For composite restorations in the posterior teeth, the mean sum-score of RF group was higher for male than female dentists (p = 0.009). For amalgam, mean score for RF was 10.2, followed by RC (8.5) and RO (1.1). Conclusion. Secondary caries and various fractures and failures predominate as dentists' perceived reasons for replacement of restorations. Private dentists included miscellaneous reasons as one of their six reasons more often than did the salaried dentists. The complex process of treatment planning and decision-making is influenced by many as of yet unknown factors, calling for emphasis on investigating of perceptions.

Chronic Maxillary Sinusitis Associated with an Unusual Foreign Body: A Case Repor

Case Reports in Otolaryngology
Volume 2012 (2012), Article ID 903714, 4 pages

Foreign bodies in maxillary sinuses are unusual clinical conditions, and they can cause chronic sinusitis by mucosal irritation. Most cases of foreign bodies in maxillary sinus are related to iatrogenic dental manipulation and only a few cases with non-dental origin are reported. Oroantral fistulas secondary to dental procedures are the most common way of insertion. Treatment is surgical removal of the foreign body either endoscopically or with a combined approach, with Caldwell-Luc procedure if endoscopic approach is inadequate for visualisation. In this case, we present a 24-year-old male patient with unilateral chronic maxillary sinusitis due to a wooden toothpick in left maxillary sinus. The patient had a history of upper second premolar tooth extraction. CT scan revealed sinus opacification with presence of a foreign body in left maxillary sinus extending from the floor of the sinus to the orbital base. The foreign body, a wooden toothpick, was removed with Caldwell-Luc procedure since it was impossible to remove the toothpick endoscopically. There was no obvious oroantral fistula in the time of surgery, but the position of the toothpick made us to think that it was inserted through a previously healed fistula, willingly or accidentally.

Parents' ability to recall past injuries to maxillary primary incisors in their children*

Sheinvald-Shusterman K, Holan G. Dent. Traumatol. 2011; ePub(ePub): ePub.
Affiliation: Department of Pediatric Dentistry, The Hebrew University - Hadassah School of Dental Medicine, Jerusalem, Israel.
DOI: 10.1111/j.1600-9657.2011.01080.x 

Abstract -  Aim:  To evaluate the ability of parents to recall past injuries to their children's maxillary primary incisors. Materials and methods:  Clinical and radiographic trauma-related major and minor signs observed in the first dental visit of 727 preschool children were recorded. Major signs included crown fracture, coronal discoloration, internal resorption, pulp canal obliteration, swelling, fistula, and periapical lesion. Minor signs included enamel cracks, sensitivity to percussion, dull or metallic sound on percussion, increased mobility, and widened periodontal ligament. Children were divided into groups: CT = certainly traumatized (presenting with at least one major sign or a combination of three minor signs), PT = probably traumatized (presenting with one or two minor signs) and NT = not traumatized. Accompanying parents were asked to recall past injuries to their children's teeth. Possible replies were 'no', 'yes' and 'probably yes'. Disagreement when both parents were present was recorded as 'yes'. Crown fractures involving dentin, coronal discoloration, swelling and fistula were defined as 'observable signs of trauma'. Results:  One-hundred and eighteen children were accompanied by fathers, 411 by mothers and 198 by both. The CT group comprised 464 children; the PT group, 103; and the NT group, 160, with no statistically significant differences by gender. Parents' positive recall was similar for boys (33.3%) and girls (31.0%). Mothers recalled trauma in 32.6% and fathers in 27.1% of their children. Parents failed to recall trauma in 52.6% of the CT-group children and in 43.5% of the PT-group children. Parents failed to recall trauma in 37.6% of the children who had observable signs of trauma. Conclusions:  Parents' recall of dental trauma occurring in their children's maxillary primary incisors was reliable in <50% of the cases.

Dentists Could Screen 20 Million Americans For Chronic Physical Illnesses

Nearly 20 million Americans annually visit a dentist but not a general healthcare provider, according to an NYU study published in the American Journal of Public Health.

The study, conducted by a nursing-dental research team at NYU, is the first of its kind to determine the proportion of Americans who are seen annually by a dentist but not by a general healthcare provider.

This finding suggests dentists can play a crucial role as health care practitioners in the front-line defense of identifying systemic disease which would otherwise go undetected in a significant portion of the population, say the researchers.

"For these and other individuals, dental professionals are in a key position to assess and detect oral signs and symptoms of systemic health disorders that may otherwise go unnoticed, and to refer patients for follow-up care," said Dr. Shiela Strauss, an associate professor of nursing at the NYU College of Nursing and co-director of the statistics and data management core for NYU's Colleges of Nursing and Dentistry.

During the course of a routine dental examination, dentists and dental hygienists, as trained healthcare providers, can take a patient's health history, check blood pressure, and use direct clinical observation and X-rays to detect risk for systemic conditions, such as diabetes, hypertension, and heart disease.

The NYU research team examined the most recent available data, which came from a nationally representative subsample of 31,262 adults and children who participated in the Department of Health & Human Services 2008 annual National Health Interview Survey, a health status study of the U.S. population, which at that time consisted of 304,375,942 individuals. Physicians, nurses, nurse practitioners, and physician assistants were among those categorized as general health care providers for the purposes of the survey.

When extrapolated to the U.S. population, 26 percent of children did not see a general health care provider. Yet over one-third of this group, representing nearly seven million children, did visit a dentist at least once during that year, according to survey results.

Among the adults, one quarter did not visit a general healthcare provider, yet almost a quarter -- nearly 13 million Americans -- did have at least one dental visit. When combined, adults and children who had contact only with dentists represent nearly 20 million people.

Ninety-three percent of the children and 85 percent of the adults had some form of health insurance, suggesting that while many of those who did not interact with a general healthcare provider may have had access to general health care, they opted not to seek it.

In vitro study of the effects of fluoride-releasing dental materials on remineralization in an enamel erosion model

Journal of Dentistry



This study was conducted to compare the remineralization effects of five regimens on the loss of fluorescence intensity, surface microhardness, roughness and microstructure of bovine enamel after remineralization. We hope that these results can provide some basis for the clinical application of these materials.


One hundred bovine incisors were prepared and divided into the following five groups, which were treated with distinct dental materials: (1) Clinpro™ XT varnish(CV), (2) F-varnish(FV), (3) Tooth Mousse(TM), (4) Fuji ? LC® light-cured glass ionomer pit and fissure sealant(FJ), and (5) Base Cement® glass polyalkenoate cement(BC). Subsequently, they were detected using four different methods: quantitative light-induced fluorescence, microhardness, surface 3D topography and scanning electron microscopy.


The loss of fluorescence intensity of CV, BC and FJ groups showed significant decreases after remineralization (p < 0.05). The microhardness values of the BC group were significantly higher than those of the other groups (p < 0.05) after 6 weeks of remineralization. The CV group's surface roughness was significantly lower than those of the other groups after 6 weeks of remineralization (p < 0.05). Regarding microstructure values, the FV group showed many round particles deposited in the bovine enamel after remineralization. However, the other four groups mainly showed needle-like crystals.


GIC-based dental materials can promote more remineralization of the artificial enamel lesions than can NaF-based dental materials. Resin-modified GIC materials (e.g., CV and FJ) have the potential for more controlled and sustained release of remineralized agents. The effect of TM requires further study.

A practice-based study on the effect of a short sucrose/xylitol exposure on survival of primary teeth caries free

ANTTONEN, V., HALUNEN, I., PÄKKILÄ, J., LARMAS, M. and TJÄDERHANE, L. (2011), A practice-based study on the effect of a short sucrose/xylitol exposure on survival of primary teeth caries free. International Journal of Paediatric Dentistry. doi: 10.1111/j.1365-263X.2011.01205.x

Background.  In a randomized double-blinded clinical trial, preschool children used sucrose or xylitol chewing gum regularly for 2 months to study the preventive effect of xylitol on acute otitis media (AOM). Salivary mutans streptococci (sm) levels of the children were measured before the exposure. Those with ≥105sm CFU in 1 mL saliva were considered to have high sm levels (sm+); and those with <105 CFU low sm levels (sm−).
Aim.  This practice-based study aims to evaluate long-term dental effects of the sucrose/xylitol exposure on primary teeth.
Design.  For analyses, individuals were divided into sub groups according to their study group in the original AOM trial and baseline sm levels. Outcome events owing to dental caries of their all primary teeth were followed from dental records up to 12 years. Survival of teeth caries free was determined by Kaplan–Meier method and analysed statistically by Wilcoxon testing.
Results.  Survival of primary teeth caries free of children with high sm levels in the sucrose group was significantly shorter compared with all other groups when followed until shedding.
Conclusions.  Two months’ regular exposure to sucrose was sufficient to induce dental caries in primary teeth of children with elevated sm levels at baseline.

Trainee dentists 'left with no job' in NHS

Despite spending more than £30m on two new dental schools to increase the numbers of dental graduates and boost access to NHS dentistry there are too few training places for them to ensure they can work in the health service, it has emerged.
It costs £250,000 to put each graduate through dental school and around 100 have been left without a place on the postgraduate training course which is compulsory for them to work in the NHS.
Their only option is to enrol in a private postgraduate course which means they will not be able to work in the NHS or leave the country and practice elsewhere.

Updating the Management of the Dental Patient at Risk for Osteonecrosis of the Jaw Bone (ONJ) While Taking Bisphosphonates or Denosumab (Prolia®) - Latest Reports from the American Dental Association

Clinical Update From LexiComp

The American Dental Association (ADA) has released two reports which update previous reports on the management of the dental patient at risk for osteonecrosis of the jaw bone (ONJ) while taking bisphosphonates. The first is a 47-page report, dated December 2011 and posted on the ADA web site, entitled "Managing the Care of Patients Receiving Antiresorptive Therapy for Prevention and Treatment of Osteoporosis: Recommendations from the American Dental Association Council on Scientific Affairs." The second report was published as an executive summary on the same topic in the December 2011 issue of the Journal of the American Dental Association. Both reports update a 2008 report on the management and care of patients receiving oral bisphosphonate therapy, which was described in an earlier newsletter by this author. This month's newsletter describes and summarizes these latest reports.
