Correlation between dental anxiety, Sense of Coherence (SOC) and dental caries in school children from Bangalore North: a cross-sectional study.

BACKGROUND: Very few publications report on the relationship between 'salutogenesis', as measured by the concept of Sense of Coherence (SOC), and generally speaking an individual's overall oral health- related quality of life (OHRQL). To add to this, there is even lesser information regarding the behavioral aspect of dental anxiety. AIM: The aim of the present study was to evaluate the relationship between dental anxiety, SOC and dental caries in school children from Bangalore North. MATERIALS AND METHODS: The study had a sample of 529 children from various schools, age between 12-16 in Bangalore north. The study comprised of 17 questions which were handed over to them; and upon receival of the questionnaire the respective decayed, missing, filled tooth surfaces index (DMFS) score was checked which was then compared with dental anxiety and SOC. STATISTICAL ANALYSIS USED: One way analysis of variance (ANOVA) F-test and multiple comparison procedures (MCPs). RESULT: High dental anxiety predicted high dental caries index and low SOC predicted high dental caries index in association with advancing children's age from 12-16 years. CONCLUSION: Dental anxiety had a direct relationship with dental caries and SOC had an inverse relationship with dental caries.

Clinical Evaluation of Resin Composite and Resin Modified Glass Ionomer in Class III Restorations of Primary Maxillary Incisors: A Comparative In Vivo Study.

UNLABELLED: Restoration of primary teeth continues to be an important facet of restorative dentistry. In comparison to restorations in permanent dentition, the longevity of those in primary teeth is significantly different for all materials. This makes the assessment of these fillings as a separate group meaningful. As there is lack of supporting clinical data with regard to the restoration of primary incisors, it would be judicious to consider why this is so and determine if studies can be designed to gain new information. The purpose of this study was therefore to evaluate and compare the clinical efficacy of composite resins and resin-modified glass ionomer cement restorations of primary incisors, over a period of one year. METHODS: The study group consisted of 40 patients (3½- 5 ½ years of age) with at least one pair of similar sized lesions in the middle1/3 of the same proximal surface of contralateral primary maxillary incisors. Composite resin and resinmodified glass ionomer cement restorations were placed in primary maxillary incisors using split-mouth design. The restorations were evaluated at different intervals of 3,6,9, months and 1 year using Ryge's criteria. Data obtained was analyzed using Mann-Whitney test. RESULTS: The results revealed no statistical significance in the difference of clinical characteristics between the two restorative materials. INTERPRETATION AND CONCLUSION: (1) Resin-modified glass ionomer cement and composite resin restorative materials showed acceptable clinical performance after 1 year in primary teeth. (2) Resin-modified glass ionomer cement and composite resin restorative materials functioned well as class III restorative materials in primary teeth.

A compound composite odontoma associated with unerupted permanent incisor: a case report.

Odontomas are the most common type of odontogenic tumors and are generally asymptomatic. Frequently they interfere with the eruption of the teeth. This is the case report of a compound composite odontoma in an 11 years old girl, which resulted in failure of eruption of the permanent maxillary right central incisor while the contralateral tooth had erupted. A calcified mass was seen in the radiograph and was provisionally diagnosed as odontoma following which the odontoma was enucleated. Routine follow-up was done for 1½ years and no recurrence was seen.

The removal of the smear layer using EGTA: a scanning electron microscopic study.

The smear layer associated with endodontic instrumentation is currently thought to be a thin layer that occludes the orifices of the dentinal tubules and covers the intertubular dentin of the prepared canal wall. The purpose of this study was to compare the effect of ethylene glycol bis (beta-amino ethyl ether)-N, N, N', N'-tetra acetic acid (EGTA) and ethylene diamine tetra acetic acid (EDTA) on removal of the smear layer through the scanning electron microscopy. Twenty four single rooted teeth were selected, instrumented and irrigated with various solutions and the specimens were processed for scanning electron microscopy. It was found that though both EGTA and EDTA completely removed the smear layer, EDTA caused erosion and conjugation of the tubules, whereas, EGTA effectively removed the smear layer without inducing any erosion. It was thus concluded that EGTA can be effectively used as an alternative chelator for the removal of the smear layer.
