Evaluation of Reliability and Validity of Occlusal Caries Detection by Direct Visual, Indirect Visual and Fluorescence Camera Using ICDAS II (Codes 0, 1, and 2): An In Vivo Study.

Introduction: Early detection of carious lesions paves the way for the preservation of tooth structures by remineralization strategies. Visual examination using international caries detection and assessment system (ICDAS) II has been validated with the gold standard of histological classification. A fluorescence camera is yet another diagnostic aid for the early detection of carious lesions based on the autofluorescence of the enamel and dentin. This study was done to evaluate the validity of the fluorescence camera (Soprocare and Acteone) in detecting early carious lesions. Materials and methods: A total of 690 occlusal surfaces of non-cavitated premolars and molars were examined by examiners 1 and 2, trained in the ICDAS II grading system. The photographs of the occlusal surface and the fluorescence images, which were taken using a Soprocare (Acetone) intraoral camera, were examined by examiners 3 and 4. The scoring was tabulated and correlated. Results: The κ values for interexaminer reproducibility of indirect visual was 0.841 (good), and his fluorescence camera was 1.00, which is very good. The correlation analysis revealed that there was a higher correlation between direct visual and indirect visual for both examiners when compared to direct and fluorescence cameras. There was a positive relationship between indirect visual and fluorescence cameras for both the experimenter). The indirect visual method for the detection of carries has high sensitivity and specificity irrespective of the examiner. Examination by fluorescence camera has a low sensitivity and high specificity. Conclusion: The specificity of the caries detection method by indirect visual examination based on ICDAS II coding that of the Soprocare fluorescence camera was consistent and reliable, whereas indirect visual examination had a high sensitivity for detecting ICDAS codes 1 and 2. Soprocare showed a very low sensitivity in detecting ICDAS code 1 and 2 lesions. How to cite this article: Dhanavel C, Sai CK, Neelamurthy PS, et al.

Knowledge, attitude and skills of dental practitioners of Puducherry on minimally invasive dentistry concepts: A questionnaire survey.

BACKGROUND: Minimally invasive dentistry (MID) encompasses early caries diagnosis through caries risk assessment (CRA), early detection of incipient carious lesion including primary and secondary prevention based on scientific evidence that remineralization of demineralized enamel and dentin is possible if detected early. Although the dental curriculum focuses on the advantages of MID in tooth preservation, this science is not usually translated into practice. AIM: This study aimed to evaluate the knowledge, attitude, and skills of dental practitioners of Puducherry regarding the concepts of MID. SUBJECTS AND METHODS: Data were collected through an online survey questionnaire based on awareness and practice of MID. Statistical evaluation was done on SPSS by Chi-square test. RESULTS: A total of 126 dentists responded of which only 55% were trained in MID during their undergraduate and internship period, mainly through lectures (49.6%). Nearly 81% agreed that CRA should be conducted for all patients. Almost 42.7% had heard about International Caries Detection and Assessment System, but only 25.9% used a blunt explorer for caries detection. About 13.7% use magnification (loupes/microscope), but majority (84.7%) use radiographs. More than 70% were unaware of newer methods of caries detection. Statistically significant differences were found (P < 0.05) regarding qualification and experience about the effectiveness of Atraumatic Restorative Treatment and sandwich technique for treatment of caries in permanent teeth and high caries-risk children. CONCLUSION: Although there is knowledge about advantages of MID among dentists of Puducherry, it does not benefit patients, as many practitioners still follow the traditional principles of total caries removal.

A comparative evaluation of the staining capacity of microhybrid and nanohybrid resin-based composite to indian spices and food colorants: An In vitro study.

INTRODUCTION: Resin composite restorative materials can mimic the natural color and shade of the tooth. However, exogenous colorants from food and drinks can stain them due to adsorption. The influence of Indian food colorants and spices on resin composite restorations has not been evaluated extensively. AIM: This study aims to evaluate the staining capacity of microhybrid and nanohybrid resin-based composites, to saffron extract, tandoori powder, and turmeric powder. SUBJECTS AND METHODS: Forty samples of microhybrid (Kulzer Charisma) and nanohybrid (3M Filtek Z350) resin composites were prepared using an acrylic template of dimension 5 mm × 3 mm. They were randomly divided into four groups and immersed into solutions of saffron extract, tandoori powder, and turmeric powder. Distilled water was used as the control group. Color values (LFNx01, aFNx01, bFNx01) were measured by colorimeter using the CIE LFNx01aFNx01bFNx01 system before and after 72 h of immersion. Color differences ΔEFNx01ab were statistically analyzed. STATISTICAL ANALYSIS USED: Two-way ANOVA and post-hoc Tukey (honest significant difference) test were done using IBM SPSS Statistics for Windows, Version 19.0. Armonk, NY: IBM Corp. RESULTS AND DISCUSSION: : All the immersion media changed the color of the resin composites to varying degrees. However, turmeric solution showed the maximum mean color variation ΔEFNx01ab of 14.8 ± 2.57 in microhybrid resin composites and 16.8 ± 3.50 in nanohybrid resin composites. CONCLUSION: Microhybrid and nanohybrid resin composites tend to stain to Indian food colorants, especially to turmeric powder.

Evaluation of the Shear Bond Strength of Composite Resin to Wet and Dry Enamel Using Dentin Bonding Agents Containing Various Solvents.

INTRODUCTION: Bonding of composite resin to dentin mandates a wet substrate whereas, enamel should be dry. This may not be easily achievable in intracoronal preparations where enamel and dentin are closely placed to each other. Therefore, Dentin Bonding Agents (DBA) are recommended for enamel and dentinal bonding, where enamel is also left moist. A research question was raised if the "enamel-only" preparations will also benefit from wet enamel bonding and contemporary DBA. AIM: The aim of this study was to compare the shear bond strengths of composite resin, bonded to dry and wet enamel using fifth generation DBA (etch and rinse system) containing various solvents such as ethanol/water, acetone and ethanol. MATERIALS AND METHODS: The crowns of 120 maxillary premolars were split into buccal and lingual halves. They were randomly allocated into four groups of DBA: Group 1-water/ethanol based, Group 2-acetone based, Group 3-ethanol based, Group 4-universal bonding agent (control group). The buccal halves and lingual halves were bonded using the wet bonding and dry bonding technique respectively. After application of the DBAs and composite resin build up, shear bond strength testing was done. RESULTS: Group 1 (ethanol/water based ESPE 3M, Adper Single Bond) showed highest bond strength of (23.15 MPa) in dry enamel. Group 2 (acetone based Denstply, Prime and Bond NT, showed equal bond strength in wet and dry enamel condition (18.87 MPa and 18.02 MPa respectively). CONCLUSION: Dry enamel bonding and ethanol/water based etch and rinse DBA can be recommended for "enamel-only" tooth preparations.

Dental caries - A complete changeover (Part I).

In spite of a knowledge explosion in cariology science, dental caries still remains a misunderstood phenomenon by the clinicians. In order to effectively use the wide range of preventive and management strategies, it is imperative to look beyond those black and white spots that manifest on the tooth surfaces. This paper focuses on the revised versions of the etiopathogenesis and definition of dental caries disease in the present century.
