The aim of the study was to compare the ICDAS, the CAST, the DMF, the Nyvad criteria and the SCI with respect to their ability in identification of caries in the individuals from six to twelve years of age and also the time required for recording each indices. Materials and Methods: A total of 47 children visiting the hospital were selected and examined. Examination was done in the dental chair with adequate light. Oral prophylaxis was done. Subsequently, examination was performed by the examiner according to DMFT system, ICDAS, CAST, Nyvad's criteria and SCI and the information forms were recorded. Chi square test and one way ANOVA were used for data analysis. Results: In this study, the no statistically significant difference was shown by number of sound teeth. For caries involving enamel, there was statistical difference seen. For caries involving dentin, Distinct/Active Cavity lesions, statistically significant difference was seen. For pulp involvement, statistically significant differences were observed. For, restored teeth, there was statistical difference but missing teeth due to caries did not show any statistically significant difference. The mean time taken to apply the DMF was 1mins 17secs; for ICDAS, 3mins 32secs, for CAST, 3min 30secs, for Nyvad's Criteria, 2mins 34secs and for SCI it took 1min 2secs. Conclusion: A common method for classification of caries identification is ambiguous. DMFT and SCI is the most simple and less time consuming method. ICDAS addresses the all the progressive stages of the caries.

Traumatic dental injuries are one of the commonly experienced dental emergencies. Missing anterior tooth in children due to any injury can be a source of considerable physical and psychological discomfort for the child. Aim: To evaluate by means of self administered questionnaire the level of knowledge of medical graduates and medical postgraduates in emergency management of tooth avulsion. Setting and Design: Questionnaire-based survey design was utilized to assess the knowledge. Materials and Methods: A survey was conducted among 50 medical graduates and medicalpostgraduates. A questionnaire was formulated to assess the knowledge and attitude among medical graduates and medical postgraduates regarding the management of avulsed tooth. A total of 50 medical graduates and 50 medical postgraduates consented to participate in the survey. Results: 28% 0f medical graduates and 18% of medical postgraduates prefer to wash with sterile saline and the rest prefer to do nothing. 34% of medical graduates and 20% of medical postgraduates prefer to take the broken tooth to the dentist whereas 16% of medical graduates and 32% of medical postgraduates do not know what to do. 45%0f medical graduates and 36% of medical postgraduates prefer to keep the tooth in correct medium whereas rest were wrong. 48% of medical graduates and medical postgraduates know that avulsed primary tooth should not be replanted. Conclusion: The study conclude that there is need for an educational lecture to widen the knowledge of the medical graduates and medical postgraduates about the emergency management of tooth avulsion which can be achieved by adding leaflets, posters about basic first aid treatment.

To evaluate the effect of virtual reality eyeglasses as a distraction technique in management of anxious paediatric patients undergoing dental treatment.: It is an in-vivo study which was performed on 148 patients with 37 in each four different groups. Children’s dental anxiety was measured using Modified Dental Anxiety Scale (MDAS) and Pulse oximeter which measures the pulse rate, oxygen saturation. After assessing the anxiety levels of the children, children who are found to be anxious were taken for the study. includes children who have to undergo extraction without virtual reality eyeglasses. includes children who have to undergo extraction with virtual reality eyeglasses. includes children who have to undergo restoration without virtual reality eye glasses. includes children who have to undergo restoration with virtual reality eye glasses. Children’s anxiety was again evaluated using the Modified Dental Anxiety Scale (MDAS) and Pulse oximeter during dental treatment. The results obtained were then compared. The data was collected, tabulated, Descriptive statistics and paired t test was used for statistical analysis. Group A: There were statistically significant changes in pulse rate, oxygen saturation (SPO) and modified anxiety scale (p<0.05). Group B: There were statistically significant changes in pulse rate and modified anxiety scale (p<0.05), but there were no statistically significant changes in the oxygen saturation (SPO)level (p>0.05). Group C: There were statistically significant changes in pulse rate and modified anxiety scale (p<0.05), but there were no statistically significant changes in the oxygen saturation (SPO) level (p>0.05). Group D: There were statistically significant changes in pulse rate and modified anxiety scale (p<0.05), but there were no statistically significant changes in the oxygen saturation (SPO)level (p>0.05)Within the limitations of this study we conclude that virtual reality eyeglasses used in the present study is an effective distraction technique in management of pediatric patients undergoing dental treatment.

To compare the clinical success rate of Prefabricated Zirconia crowns and stainless steel crowns on primary molars: It is an in-vivo study which was performed on 52 pulpally treated primary molars of children aged 4–9 years were randomly divided into two equal groups of stainless steel crown and Prefabricated Zirconia crowns. Tooth preparation was done according to the manufacturer’s recommendations and crowns were cemented. All crowns were cemented with Type I Glass ionomer cement (GIC) luting cement. Crowns were evaluated clinically for its crown retention, marginal integrity and gingival health at 3 months and 6 months.: Clinical success for stainless steel crowns and Prefabricated Zirconia crowns towards crown retention and marginal integrity were similar with no statistical difference between them. All Prefabricated Zirconia crowns showed healthy gingiva whereas 53.8% (14 out of 26) Stainless Steel crowns showed mild gingival inflammation at 3 and 6 months which was statistically significant (P ≤0.01). Both prefabricated zirconia and stainless steel crowns showed no statistical difference for crown retention and marginal integrity throughout the study. Gingival health was significantly higher for Prefabricated Zirconia crowns compared with stainless steel crowns. Therefore clinical success rate for Prefabricated Zirconia crowns were better when compared to stainless steel crowns. So Prefabricated Zirconia crowns can be considered as an esthetic alternative in future.
