Ensuring clinical success begins with a careful discussion of treatment planning, comprehensively covering all variables in simple to complex cases. Procedures including the crown lengthening surgery, furcation treatment and mucogingival therapy and tooth restoration are essential treatment regimens requiring multifaceted expertise. The interplay of periodontics and restorative dentistry is present at many fronts including the response of the gingival tissue to the restorative preparations. Dental restorations and periodontal health are inseparably interrelated. The adaptation of the margins, the contours of the restoration, the proximal relationships and the surface smoothness have a critical biological impact on the gingiva and the supporting periodontal tissues. The different surgical procedures used for crown lengthening are gingivectomy/gingivoplasty, apically positioned flap with or without osseous resection and orthodontic extrusion. The paper presents crown lengthening of severely mutilated teeth to increase the clinical crown height for adequate restoration.
Endodontic treatment may sometimes fail because morphological features of the tooth adversely affect the treatment procedures. Many investigators have reported the anatomical variations associated with mandibular canines. Mandibular canines are recognized as usually having one root and one root canal in most cases. This case report describes a clinical case of mandibular canine with two canals. Human
INTRODUCTION: Bleaching, although considered as the first choice of treatment for discoloured teeth, can be utilized in conjunction with composite resin bonding or veneering and porcelain laminate veneers, to provide a more esthetic result. AIM: The aim of the ex-vivo study is to obtain a comparative analysis to evaluate the effectiveness of antioxidants on the immediate composite bond strength on bleached enamel surface.MATERIALS AND METHOD: Freshly extracted human permanent maxillary central incisors were selected and prepared for the respective study. All the specimens then were randomly divided into two control groups and three experimental groups, each group consisting of 20 specimens each. Among these were three experimental groups 10% Sodium Ascorbate, 5% Grape Seed extracts (Proanthocyanidin, PA) & 10% Green tea extracts (catechins and epigallocatechin gallate, CA and EG) and two control groups (Positive control & Negative control).RESULTS: When compared to Group 1 (positive control, 26.24 ± 0.90 MPa ), Group 3 (5%Grape seed extract; 32.17 ± 1.52 MPa), Group 4 (10% Sodium Ascorbate; 28.91 ±1.50 MPa ) and Group 5 (5% Green tea extract; 24.10 ± 1.21MPa ) showed significantly higher shear bond strength values.CONCLUSION: The present study indicated that the shear bond strength of the antioxidant group (Group3) is higher than all three experimental groups. In addition, the shear bond strength of the bleached group (Group 2) is significantly lower than all the other groups. This implies that immediate use of antioxidants, contributes in reversal the bond strength of bleached enamel.
The aim of this study is to compare oral-health knowledge, attitude and self-care practice behavior among medical students. Materials and Methods: A cross sectional study was carried out on 1 st year MBBS students. All the students present on the day of data collection were included in the study. Data was collected by pretested questionnaire and analysed using percentages. Results: Awareness among students about oral hygiene was good. All students in our study were brushing the teeth at least daily with toothbrush and paste. Only few students (6.92%) were using fluoride toothpaste and 93.07% were unaware of fluoride content. Nearly all students restrained from Alcohol Consumption and Tobacco Use. About 23.84% students had Pain /Discomfort in Past 12 Months and 16.15% consulted dentist. About 57% students visited dentist in last 5 years and most common reason was toothache. Conclusions: The better result among medical students could be due to their better knowledge and socioeconomic conditions. Developing countries show lack of awareness and poor oral hygiene habits among large sections of the population, increasing the risk of oral health problems. More awareness should be created among general population to improve the oral health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
