Background:Mothers play a key role as transmitters of oral health behavior for their children. Hence increasing their knowledge about positive attitude toward desirable oral health behaviors regarding their children will lead to the better oral health of the children.Aim:The aim was to evaluate the effectiveness of oral health education program among mothers with 6-18 months old children in the prevention of early childhood caries.Materials and Methods:A total of 480 mothers with 6-18 months old children were selected using cluster randomization of the primary health center. The allocated mothers were assigned into three groups: Motivation group (group A), traditional health education group (group B) and control group (group C). Clinical examination was carried out to record the dental decay of the child.Statistical Analysis:The data was analyzed using SPSS 13. Evaluation of statistical significance between groups was made using the Chi-square test, ANOVA and Kruskal-Wallis.Results:Mean number of decayed teeth was 0.23 + 0.58 in group A that was significantly less as compared to 0.39 + 0.79 and 1.17 + 1.32 in group B and C, respectively.Conclusion:Motivational intervention was more effective in reducing dental decay in the children as compared to the other two groups.

Aim:The aim was to assess the knowledge, attitude and practices among undergraduate dental students about oral cancer.Materials and Methods:A cross-sectional questionnaire study was conducted among undergraduate dental students between the 3rd and 5th years in H.P Government Dental College, Shimla. The questionnaire consisted of 15 questions, five each on knowledge, attitudes and practices. The data were analyzed by Statistical Package for the Social Sciences (SPSS Inc., version 16 for Windows, Chicago, IL, USA).Results:The response rate of the study was 90.6%. There were 23 (21.5%) males and 84 (78.5%) females in the study. There was a predominance of females (78.5%). The average knowledge percentage for the entire population is 81.9% (excellent knowledge). Tobacco and alcohol were correctly identified by 63.5% of the subjects. Squamous cell carcinoma was described as the most common type of oral cancer by 105 (98.3%) of the students. 60.7% of the subjects strongly disagreed that their knowledge regarding the prevention and detection of oral cancer is current and adequate, and 99% agreed that there is a need for additional training/information regarding oral cancer. About 92.5% of the subjects used to educate their subjects about the harmful effects of tobacco and alcohol.Conclusion:The study implies that the knowledge, especially about the etiological factors of oral cancer needs to be reinforced throughout the undergraduate dental courses so that they can use the same in educating and motivating the masses to adapt healthy lifestyles.

Introduction Extraction of teeth is followed by resorption of the residual alveolar ridge that continues throughout life resulting in loss of alveolar height and width. Of the numerous techniques that have been used to arrest post extraction alveoloar ridge resorption, the placement of a graft material inside the socket immediately after extraction has been mostly followed. Type 1 collagen is one of the commonly used graft material that prevent resorption by providing dimensional stability to the socket.Bisphosphonates are an anti-osteoclastic drug that prevent resorption by disrupting the membrane ruffling of the osteoclasts. Alendronate a bisphosphonate, is primarily used in diseases with bone loss. It has been used to reduce active bone resorption significantly without interfering with bone mineralization and quality. The need for the study is to examine the inhibitory effect of alendronate on residual ridge resorption when applied locally in combination with type I collagen on alveolar bone immediately following tooth extraction. Materials and Methods Twenty patients with age between 30 and 65 years were selected from the out patient department of The Oxford Dental College and Hospital. The patients were divided into two groups. In the first group after extraction of teeth from premolar to midline the sockets were irrigated with saline and sutured. On the left side type I collagen sponge was placed and sutured. In the other group the right side was treated the same way after extraction as in first group where as in the left side sockets type I collagen soaked in 20 mg/ml of alendronate was placed and sutured. Patients were evaluated clinically for any local irritation as well as radiologically with orthopantomograph X-rays were taken immediately after the extraction, 1 month after extraction and 4 months after extraction to determine the amount of bone loss prevented. Results The statistically significant bone loss prevented by the collagen alone was 22.8 % and in collagen with alendronate group was 44.38 % at the end of 4 months. Conclusion Type I collagen soaked with alendronate when placed in the socket immediately after extraction of teeth prevents post-extraction alveolar ridge resorption.
