Rossi F, Lang NP, Ricci E, Ferraioli L, Marchetti C, Botticelli D. Early loading of 6-mm-short implants with a moderately rough surface supporting single crowns – a prospective 5-year cohort study. Clin. Oral Impl. Res. 00, 2014, 17 doi: 10.1111/clr.12409

 

Abstract

Aim

To evaluate prospectively the clinical and radiographic outcomes after 5 years of early loading of 6-mm implants with a moderately rough (SLActive®) surface supporting single crowns in the posterior regions.

Material and methods

Thirty-five consecutive patients received 40 SLActive® (Straumann) 6-mm implants with a diameter of 4.1 mm (n = 19) or 4.8 mm (n = 21). Insertion torque and resonance frequency analysis (RFA) were measured at implant installation. RFA was also measured at abutment connection. SynOcta abutments were tightened with 35 Ncm after 6 weeks of healing, and single porcelain fuse to metal crowns was cemented within 1 week. Implant survival rate and marginal bone loss were evaluated at various time intervals until 5 years after loading. The clinical crown/implant ratio was calculated as well.

Results

Two of 40 implants were lost before loading (incorporation rate 95%), and no further implant loss or technical complications were encountered during the 5-year follow-up period. A mean marginal bone loss of 0.7 ± 0.6 mm was found after 5 years of function. The clinical crown/implant ratio increased with time from 1.6 at the delivery of the prosthesis to 2 after 5 years of loading.

Conclusion

Six millimeter implants with a SLActive® moderately rough surface supporting single crowns in the posterior region and loaded after 6–7 weeks maintained full function for at least 5 year with low marginal bone resorption.

Role of Probiotics on Oral Health - A Randomized, Double Blind, Placebo-Controlled Microbiological Study

Shivani Dhawan and Rajan Dhawan (2013), "Role of Probiotics on Oral Health - A Randomized, Double Blind, Placebo-Controlled Microbiological Study," Journal of Research and Practice in Dentistry, Vol. 2013 (2013), Article ID 736993, DOI: 10.5171/2013.736993
Abstract


The aim of this study was to investigate commercially available combined probiotic formulation for its effect on plaque, gingivitis and salivary Streptococcus mutans levels in subjects with chronic gingivitis. A total of 36 subjects were finally enrolled in a double blind placebo controlled randomized trial. Selected subjects were randomly divided in two groups; Group A (Control group) with 17 subjects, receiving placebo tablets twice daily and Group B (Probiotic group) with 19 subjects receiving probiotic tablets twice daily. The study consisted of two 2 weeks periods, a two week intervention period (T1-T2) and a two week post treatment period (T2-T3). Clinical parameters and bacterial counts of salivary Streptococcus mutans, were evaluated at the baseline (T1), at the completion (T2) of medication and 2 weeks after medication (T3). On comparative evaluation between the two groups, results indicated that Group-B (Probiotic group) exhibited statistically significant reduction in Plaque Index, Gingival index and Streptococcus mutans level than Group-A (Control group) over the entire span of the study. Our results indicated that probiotic could be useful in the improvement/ maintainance of oral health.

3M™ True Definition Scanner and Straumann® CARES® Provide Easy-to-Use, All-Digital Process for Implant- and Tooth-Borne Restorations


New Trusted Connection lets dentists access Straumann solutions easily

ST. PAUL, Minn. – (April 23, 2014) – 3M is pleased to announce a Trusted Connection to dental labs with the Straumann® CARES® System[1] for the 3M™ True Definition Scanner. With this new connection, dentists can restore Straumann implants with original CARES® prosthetic solutions from a single intra-oral scan. This new digital restoration process is the latest addition to a growing network of Trusted Connections available to dentists with the 3M True Definition Scanner.
“This new connection gives dentists a simple but powerful tool to initiate a highly sophisticated workflow,” said David Frazee, vice president and general manager, 3M Digital Oral Care. “The final results are not only accurate and effective, but convey an impressive image to patients that lets them know their dentist is on the cutting edge.”
Using the new workflow, a dentist with the 3M True Definition Scanner simply captures a digital impression with the Straumann® CARES® Mono Scanbody. Within the scanner’s prescription screen, the dentist then selects the Straumann implant platform and the desired tooth-borne restoration or abutment. The digital impression and prescription are then sent to a dental lab using the Straumann® CARES® system.

The dental lab can then design and order original prosthetics for implant-borne or tooth-borne restorations. For implant cases, Straumann® CARES® X-Stream™ provides a seamless process for designing and ordering the abutment and the final restoration in a single design. High precision resin working models with a socket for the Straumann® Repositionable Implant Analog can be ordered directly from Innovation MediTech (a DREVE company). The dental lab then receives the restoration, abutment and model for finishing, and the dentist receives the completed case in a single shipment from the dental lab.
“The Trusted Connection is a great example of how we have teamed up with leading providers of intraoral scanning technology to offer more options, simpler solutions, greater precision and higher productivity to dental professionals,” said Frank Hemm, executive vice president – customer solutions & education, Straumann. “Together with 3M ESPE, Dental Wings and Innovation MediTech, we offer a completely digital workflow – from digital impression to finished CAM prosthetic – with what we believe is an unparalleled level of choice, flexibility and precision.”
This new Trusted Connection is available to dentists who subscribe to the Advanced Data Plan offered with the 3M True Definition Scanner in North America. The Advanced Data Plan is a subscription to the 3M Connection Center, allowing dentists to send and store cases for a variety of indications including digital implant workflows and clear aligner treatment from Invisalign.  All of the affordable, subscription-based data plan packages for dentists or labs include unlimited software upgrades and updates, so users always have the latest software without unexpected fees. 
The Trusted Connection will be available in the U.S., Belgium, Canada, Spain, Portugal, and in the Netherlands in Summer 2014, with further European countries to follow in Fall 2014.

Adjunctive application of chlorhexidine and ethanol-wet bonding on durability of bonds to sound and caries-affected dentine

Available online 13 April 2014

 

Abstract

Objectives

To examine the effect of adjunctive application of chlorhexidine (CHX) and ethanol-wet bonding (EWB) on bond durability and nanoleakage of hydrophobic adhesive to sound (SD) and caries-affected dentine (CAD).

Methods

Dentine surfaces of molars were etched after caries removal and randomly allocated to four groups (n = 12). In Groups 1 and 2, dentine surfaces were saturated with either 2 ml of 100% ethanol or 2 ml of ethanol with 2% CHX for 60 s. In Groups 3 and 4, dentine surfaces were saturated with either 15 μL of distilled water or 15 μL of distilled water with 2% CHX for 60 s. Two coats of primer, followed by neat resin were applied and light-cured for 40 s. Resin composite build-ups were placed and bonded specimens were sectioned for bond strength testing after 24 h and 12 months’ storage in artificial saliva. Bond strength data were analyzed using 3-way ANOVA and SNK tests. Interfacial nanoleakage was evaluated after 24 h and 12 months using a field-emission scanning electron microscopy and data were analyzed using Kruskal–Wallis test.

Results

Significant differences were observed for the three factors: “substrate” (p < 0.001), “rewetting agents” (p < 0.001) and “time” (p < 0.001) on bond strength. Incorporation of 2% CHX to EWB preserved bond strength to SD and CAD and reduced interfacial nanoleakage after 12 months. Incorporation of 2% CHX to WWB also preserved bond strength to SD after ageing.

Conclusions

Incorporation of chlorhexidine to ethanol-wet bonding has an interaction effect on preservation of bond durability to sound and caries-affected dentine.

Clinical significance

Incorporation of chlorhexidine to ethanol-wet bonding with hydrophobic adhesive enhances the success rate of aesthetic bonded restorations.

American Academy of Periodontology Launches National Campaign, “Love the Gums You’re With”

-->


Educational campaign urges Americans take action against highly prevalent, yet seriously overlooked periodontal disease.

Chicago, IL – April 22, 2014 — In light of the recent prevalence data that finds almost half of American adults age 30 and older are suffering from periodontal disease, the American Academy of Periodontology (AAP) is launching a national consumer awareness campaign devoted to educating the public on the importance of prevention and early diagnosis of periodontal disease.

The campaign, “Love The Gums You’re With,” is aimed at teaching Americans to take better care of their gums by implementing simple steps into their routine, such as brushing twice a day, flossing daily, and receiving an annual comprehensive periodontal evaluation from their general dental professional or periodontist.

To gain national awareness and to help consumers better understand periodontal disease, the AAP is teaming up with Chris Harrison, host of ABC’s “The Bachelor,” to launch these efforts. In Harrison’s role as Bachelor host, he has become a love guru of sorts, having garnered the experience to know what goes into making a successful long-term relationship.  Harrison will help patients understand how to ensure a life-long relationship with healthy gums.

“On behalf of the AAP, we’re extremely excited to have the opportunity to educate the public about the high prevalence of periodontal disease,” shares Stuart J. Froum, DDS, president of the American Academy of Periodontology, clinical professor, and director of clinical research at New York University’s Department of Periodontics and Implant Dentistry. “We’re hopeful that increased awareness about this common disease and its link to other chronic diseases, such as diabetes, cardiovascular disease, rheumatoid arthritis, Alzheimer’s disease and even cancer, will drive more patients to visit their dental practitioner and focus on preventive care and early treatment, if necessary.”

Over the course of the campaign, patients may visit their dentist or a periodontal specialist for additional information about periodontal disease prevention and treatment. You may contact your referral periodontist or visit perio.org for more information.  

About the American Academy of Periodontology:
The American Academy of Periodontology (AAP) is the professional organization for periodontists – specialists in the prevention, diagnosis, and treatment of diseases affecting the gums and supporting structures of the teeth, and in the placement of dental implants. Periodontists are also dentistry’s experts in the treatment of oral inflammation. They receive three additional years of specialized training following dental school, and periodontics is one of the nine dental specialties recognized by the American Dental Association. The AAP has 8,300 members worldwide. For more information visit perio.org.

Comparative Evaluation of the Effects of Ozone, Diode Laser, and Traditional Cavity Disinfectants on Microleakage



ifa Güne, Emrullah Bahsi, Bayram nce, Hakan Çolak, Mehmet Dalli, zzet Yavuz, Cafer Sahbaz & Suzan Cangül (2014) Comparative Evaluation of the Effects of Ozone, Diode Laser, and Traditional Cavity Disinfectants on Microleakage, Ozone: Science & Engineering: The Journal of the International Ozone Association, 36:2, 206-211, DOI: 10.1080/01919512.2013.842888


Aim: This study aimed to evaluate the effects on microleakage of the application of ozone gas, laser and tra- ditional cavity disinfection under in vitro conditions. 

Material and Methods: Ninety third-molar teeth extracted for various reasons were used in this study. All the teeth were prepared with a standard V cavity on the buccal sur- face. Then the teeth were randomly allocated to one of 6 groups of 15 teeth; Group 1 benzalkonium chloride, Group 2 chlorhexidine gluconate, Group 3 sodium hypochloride, Group 4 diode laser, Group 5 ozone gas, Group 6 control group- no disinfection was applied. Primer was applied to the cavities, then bond and 10-s polymerization. Clearfil AP-X was used in the cavities as a hybrid composite and poly- merized for 20 s. The samples then underwent 1000 thermal cycles of 30-s application, in baths at temperatures between 5 ± 2 C and 55 ± 2 C. All the samples were stirred in 0.5% basic phuxine solution and the sections taken under stereomicroscope were examined and photographed at 15 × magnification. SEM analysis was made and the obtained results were statistically evaluated with the Kruskal–Wallis test. 

Results: No significant difference was seen between the groups in respect of the microleakage values of both the occlusal and gingival edges (p > 0.05). Comparison of the microleakage values of the occlusal and gingival edges of the groups determined the least leakage to be in the ozone group (p > 0.05). 

Conclusion: No statistical significance was determined between the groups. However, the mean least microleakage was found in the ozone group and the highest amount in the control group.

The effect of oral appliances that advanced the mandible forward and limited mouth opening in patients with obstructive sleep apnea: A systematic review and meta-analysis of randomised controlled trials

Cover image for Vol. 41 Issue 4
Journal of Oral Rehabilitation
Early View (Online Version of Record published before inclusion in an issue

 

Summary

Oral appliances (OAs) have demonstrated efficacy in treating obstructive sleep apnea (OSA), but many different OA devices are available. The Japanese Academy of Dental Sleep Medicine supported the use of OAs that advanced the mandible forward and limited mouth opening and suggested an evaluation of their effects in comparison with untreated or CPAP. A systematic search was undertaken in 16 April 2012. The outcome measures of interest were as follows: Apnea Hypopnea Index (AHI), lowest SpO2, arousal index, Epworth Sleepiness Scale (ESS), the SF-36 Health Survey. We performed this meta-analysis using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) system. Five studies remained eligible after applying the exclusion criteria. Comparing OA and control appliance, OA significantly reduced the weighted mean difference (WMD) in both AHI and the arousal index (favouring OA, AHI: −7·05 events h−1; 95% CI, −12·07 to −2·03; P = 0·006, arousal index: −6·95 events h−1; 95% CI, −11·75 to −2·15; P = 0·005). OAs were significantly less effective at reducing the WMD in AHI and improving lowest SpO2 and SF-36 than CPAP, (favouring OA, AHI: 6·11 events h−1; 95% CI, 3·24 to 8·98; P = 0·0001, lowest SpO2: −2·52%; 95% CI, −4·81 to −0·23; P = 0·03, SF-36: −1·80; 95% CI, −3·17 to −042; P = 0·01). Apnea Hypopnea Index and arousal index were significantly improved by OA relative to the untreated disease. Apnea Hypopnea Index, lowest SpO2 and SF-36 were significantly better with CPAP than with OA. The results of this study suggested that OAs improve OSA compared with untreated. CPAP appears to be more effective in improving OSA than OAs.

Anti-Streptococcal activity of Brazilian Amazon Rain Forest plant extracts presents potential for preventive strategies against dental caries

Journal of Applied Oral Science
Print version ISSN 1678-7757
J. Appl. Oral Sci. vol.22 no.2 Bauru Mar./Apr. 2014
http://dx.doi.org/10.1590/1678-775720130366 

Caries is a global public health problem, whose control requires the introduction of low-cost treatments, such as strong prevention strategies, minimally invasive techniques and chemical prevention agents. Nature plays an important role as a source of new antibacterial substances that can be used in the prevention of caries, and Brazil is the richest country in terms of biodiversity.

Objective:
In this study, the disk diffusion method (DDM) was used to screen over 2,000 Brazilian Amazon plant extracts against Streptococcus mutans.

Material and Methods:
Seventeen active plant extracts were identified and fractionated. Extracts and their fractions, obtained by liquid-liquid partition, were tested in the DDM assay and in the microdilution broth assay (MBA) to determine their minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs). The extracts were also subjected to antioxidant analysis by thin layer chromatography.

Results:
EB271, obtained from Casearia spruceana, showed significant activity against the bacterium in the DDM assay (20.67±0.52 mm), as did EB1129, obtained from Psychotria sp. (Rubiaceae) (15.04±2.29 mm). EB1493, obtained from Ipomoea alba, was the only extract to show strong activity against Streptococcus mutans (0.08 mg/mL

Conclusions:
The active extracts, discovered in the Amazon rain forest, show potential as sources of new antibacterial agents for use as chemical coadjuvants in prevention strategies to treat caries.

Histological changes within dental pulps in teeth with moderate to severe chronic periodontitis

Cover image for Vol. 47 Issue 4

Abstract

Aim

To investigate the effect of chronic periodontitis on dental pulps by assessing histological changes in the pulps of teeth with moderate to severe periodontitis.

Methodology

A total of 242 teeth from 162 patients with moderate to severe periodontitis were collected, and histological changes in pulps were investigated by staining with haematoxylin and eosin. Baseline data were taken from the patients’ records before extraction. The morphologic changes observed in the pulp were classified as degreeI, degree II, degree III, degree IV. Statistical analysis of the severity of periodontitis and histological changes with the pulps was applied to Mann–Whitney U rank sum test, while the contingency coefficient was used to analyze the interrelationship between the severity of periodontitis and histological changes in the pulps.

Results

The interrelationship between the severity of periodontitis and histological changes in the pulps was 0.274 (P<0 .001="" and="" between="" differences="" em="" existed="" group="" moderate="" periodontitis="" severe="" significant="" teeth="" with="">P

Liberia: 'One Dentist Serving 700,000 Patients in Liberia'





Monrovia — "In Liberia, we have seven dentists, one to seven hundred thousand and we have fifteen counties and twelve out of those counties, do not have dentists. In JFK, we will have 10-15 deaths yearly," Dr. Ayele Ajavon Cox.
As a way of creating awareness, World Oral Health Day on Thursday was observed at the Ministry of Health & Social Welfare where school children teeth were cleaned and hundreds of toothbrushes and toothpastes were distributed among the pupils.
Celebrating the first world oral health Day in Liberia, Dr. Ayele Ajavon Cox, DMD Hygienist Dental Therapist/practitioner, known to be the foot soldier in collaboration with Smile for Liberia, observed the day through the reaction of awareness.
Looking at Liberia's statics of one Dentist to seven hundred Thousand and her own story of how she became a foot soldier, Dr. Cox said ninety percent of the world suffers toothache sixty percent have access.
"Why I am the foot soldier is because when I was 12 years old, my cousin Yede Baker and I lived in Grand Cape Mount County with her father and my Uncle JDK Baker. And one year he decided to bring my cousin and I to Monrovia because all during the year we were complaining about our teeth. There were no roads to Monrovia, only boats and canons, but we walked two days to come to Monrovia because my uncle said the boats and canoes were safe to travel. And we arrived in Monrovia to a Dentist called Dr. Townsend and he extracted our teeth."
She said it was then, that she realized that she and her cousin were lucky because they had the opportunity to see a Dentist. "There were several others in Cape Mount who would have never been able to afford a dental treatment. So I decided to become a dentist. This is why I am the foot soldier."
Mrs. Yah Martor Zolia, Deputy Minister of Planning and Research Development, Ministry of Health & Social Welfare, gave the keynote address under the theme: 'Do you know that your oral health could affect your overall body health?'
She said the aim of the day is to create a need for a robust sensitization campaign locally and internationally. According to her, ninety percent of the world population will suffer oral health problems in their lifetime, which could be avoided.
"The incident of oral cancer is between one to ten cases per hundred thousand in most countries, because oral cancer is the eighth most common form of cancer in the world and the most costly to treat. Therefore, we need a robust oral health sensitization campaign because the risk for oral cancer, is fifteen times higher when the two main risk factors which are tobacco and alcohol consumption which are common in Liberia."
She said Liberia needs this campaign because over ninety percent of children here have not seen a dentist or had a dental treatment. "We need it because we have only seven dentists in Liberia and the ratio is one dentist to seven hundred thousand persons. A free government support, health and association, societal support, forming of prevention, infections and treatment programs can help avoid these problems. We also need to create relevant social programs to sensitize the public."
At the program, little Daniel Ireland, gave a testimony of his friend who died from toothache.
"Our friend had teeth and we told our grandmother and she sent him to see Dr. Cox at JFK for treatment and after his treatment, he was due back to the hospital on Monday when Dr. Cox did not see him at the hospital, she called Grandma, and when Grandma called his home to find out what happened, she found out that he was taken to the sick bush. Grandma made them bring him back to the hospital, but sadly a few days later, he died. The people in the community said it was poison because tooth could not just kill people like that."
Kormassa Baysay, a baby mother who had toothache when she was pregnant, also gave her experience during her pregnancy but she survived. Dr. Cox said they don't normally give pregnant women antibiotic, but due to Kormassa's case that survived a surgery, she took very strong antibiotics and it did not harm the baby whom she named Mr. JFK.
Dr. Taylor Neal, who is another Dentist said he and Dr. Cox are the only two Liberians dentists in the country and they are nearing retirement because they are old and cannot go on forever. "We are fading out, so we need more dentists and many of the Liberian dentists are in the US, so the government will have to offer salaries that will attract them home to come and work."
Some recommendations at the end of the program included calls for the ministries of health and Education to infuse oral health into the school's curriculum. Thus, many believe to make more medical persons be trained locally and internationally to become a Dentist.

Soft tissue wound healing around teeth and dental implants.

J Clin Periodontol. 2014 Apr;41 Suppl 15:S6-S22. doi: 10.1111/jcpe.12206.Abstract

AIM:

To provide an overview on the biology and soft tissue wound healing around teeth and dental implants.

MATERIAL AND METHODS:

This narrative review focuses on cell biology and histology of soft tissue wounds around natural teeth and dental implants.

RESULTS AND CONCLUSIONS:

The available data indicate that: Oral wounds follow a similar pattern. The tissue specificities of the gingival, alveolar and palatal mucosa appear to be innately and not necessarily functionally determined. The granulation tissue originating from the periodontal ligament or from connective tissue originally covered by keratinized epithelium has the potential to induce keratinization. However, it also appears that deep palatal connective tissue may not have the same potential to induce keratinization as the palatal connective tissue originating from an immediately subepithelial area. Epithelial healing following non-surgical and surgical periodontal therapy appears to be completed after a period of 7-14 days. Structural integrity of a maturing wound between a denuded root surface and a soft tissue flap is achieved at approximately 14-days post-surgery. The formation of the biological width and maturation of the barrier function around transmucosal implants requires 6-8 weeks of healing. The established peri-implant soft connective tissue resembles a scar tissue in composition, fibre orientation, and vasculature. The peri-implant junctional epithelium may reach a greater final length under certain conditions such as implants placed into fresh extraction sockets versus conventional implant procedures in healed sites.

Biology of soft tissue wound healing and regeneration - Consensus Report of Group 1 of the 10th European Workshop on Periodontology

J Clin Periodontol. 2014 Apr;41 Suppl 15:S1-5. doi: 10.1111/jcpe.12221.

Abstract

BACKGROUND:

The scope of this consensus was to review the biological processes of soft tissue wound healing in the oral cavity and to histologically evaluate soft tissue healing in clinical and pre-clinical models.

AIMS:

To review the current knowledge regarding the biological processes of soft tissue wound healing at teeth, implants and on the edentulous ridge. Furthermore, to review soft tissue wound healing at these sites, when using barrier membranes, growth and differentiation factors and soft tissue substitutes.

COLLECTION OF DATA:

Searches of the literature with respect to recessions at teeth and soft tissue deficiencies at implants, augmentation of the area of keratinized tissue and soft tissue volume were conducted. The available evidence was collected, categorized and summarized.

FUNDAMENTAL PRINCIPLES OF ORAL SOFT TISSUE WOUND HEALING:

Oral mucosal and skin wound healing follow a similar pattern of the four phases of haemostasis, inflammation, proliferation and maturation/matrix remodelling. The soft connective tissue determines the characteristics of the overlaying oral epithelium. Within 7-14 days, epithelial healing of surgical wounds at teeth is completed. Soft tissue healing following surgery at implants requires 6-8 weeks for maturation. The resulting tissue resembles scar tissue. Well-designed pre-clinical studies providing histological data have been reported describing soft tissue wound healing, when using barrier membranes, growth and differentiation factors and soft tissue substitutes. Few controlled clinical studies with low numbers of patients are available for some of the treatments reviewed at teeth. Whereas, histological new attachment has been demonstrated in pre-clinical studies resulting from some of the treatments reviewed, human histological data commonly report a lack of new attachment but rather long junctional epithelial attachment and connective tissue adhesion. Regarding soft tissue healing at implants human data are very scarce.

CONCLUSIONS:

Oral soft tissue healing at teeth, implants and the edentulous ridge follows the same phases as skin wound healing. Histological studies in humans have not reported new attachment formation at teeth for the indications studied. Human histological data of soft tissue wound healing at implants are limited.

CLINICAL RECOMMENDATIONS:

The use of barriers membranes, growth and differentiation factors and soft tissue substitutes for the treatment of localized gingival/mucosal recessions, insufficient amount of keratinized tissue and insufficient soft tissue volume is at a developing stage.

THE CANARY SYSTEM BOLSTERS CLAIMS TO DETECT INTERPROXIMAL CARIES


Quantum Dental Technologies (QDT) announced findings further confirming that The Canary System® can detect caries on interproximal surfaces. The findings were formally presented at the American Association of Dental Research (AADR) Meeting in Charlotte, North Carolina last week.
“Detection of interproximal caries is the final frontier in the detection of tooth decay”, said Dr. Stephen Abrams, President of QDT. “The sensitivity using X-rays and visual inspection methods is inadequate. By the time caries or decay is visible on a radiograph, the lesion is already at least 60% into the dentin, requiring a restoration or filling. Now with The Canary System, clinicians can make more informed decisions regarding diagnosis and treatment planning. By finding small lesions before they are visible on x-rays, the dentist can offer a more conservative restoration or possibly try to remineralize or stabilize these lesions.
The energy conversion technology, PTR-LUM, that powers The Canary System enabled investigators, blinded to the samples, to distinguish teeth that were healthy from those that had caries. The data presented at AADR indicates that The Canary System offers a sensitivity of 0.7 versus 0.2 when employing radiographic examination or 0.4 with visual inspection using the ICDAS II ranking system. Using polarized light microscopy as the validation tool, the status (caries/non-caries) of each examined interproximal surface was confirmed.
Unlike other devices, The Canary System detects tooth decay by examining the actual crystal structure of the teeth. In addition, the system’s interactive software and customized patient reports engage patients in their own oral healthcare, and help them understand and accept the prescribed treatment plan.
