Background: Dentin hypersensitivity is described as “short sharp pain arising from exposed dentin in response to various stimuli typically thermal, evaporative, tactile, osmotic or chemical and cannot be ascribed to any other form of dental defect or disease.” Dentine hypersensitivity can be treated with various desensitizing agents ,where oral rinse has a promising effect in delivering the therapeutic effect all over the tooth surface including interproximal areas, as they can flow and reach areas where toothpastes are not much effective, hence the occlusion of dentinal tubules using Ayurdhantam medicated an herbal mouthwash was evaluated. Methodology: Twenty such dentinal blocks were obtained; the surfaces of each dentin block were polished using a silicon carbide disc for 30 s to create a basic smear layer. The smear layer is finally detached by applying 17% EDTA solution onto the dentin blocks for 5 min to ensure the patency of the dentinal tubules, following which they were rinsed with distilled water. The specimens were placed into the Ayurdhantam solution (medicated) for 2 min every day for 7 days. The specimens were stored in artificial saliva during the study. The specimens were analyzed under scanning electron microscope (SEM) for the occlusion of dentinal tubules. Results: SEM images showed the partial occlusion of the tubules and a large amount of smear layer. Conclusions: Based on this in vitro experiment carried out, it is shown that Ayurdhantam-medicated mouthwash can be used for treating dentine hypersensitivity effectively.

Introduction: Several studies have found that certain diseases are associated with ABO blood groups. The aim of the present study was to investigate the correlation of ABO Rh blood group with dental malocclusion in the population of Mysuru. Materials and Methods: In this study patients of 15–28 years of age will be selected, irrespective of gender from the hospital, Mysuru. It is an observational study with a duration of 3–4months. A total of 278 subjects between the age group of 15-28 years who visited the JSS hospital, Mysuru were recruited for this study. The maxillary and mandibular molar relation of teeth in maximum intercuspation using Angle’s classification were recorded. Blood group was evaluated using the ABO blood grouping system. Mean, Standard deviation, frequency, percentage were used for descriptive statistics. Chi-square test was used for inferential statistics. Statistical Package of Social Science (SPSS), version 16 was used for statistical analysis. Results: Out of 278 people ‘O’ blood group was found to be most commonly associated with Angle’s Class I malocclusion (71.3%). Class II div I and div II was found to be more common in ‘A’ blood group (42.68%) and (4.9%) respectively. Class III being most common in ‘B’ blood group (6.5%). Conclusions: A significant correlation exists between blood group and malocclusion. The prevalence of malocclusions being highest in blood group O, followed by A, B and AB in Mysuru. Class II div I malocclusion was more prevalent in ‘A’ followed by ‘B’ blood group.

Introduction: The various research studies conducted in India have shown the prevalence of malocclusion ranging from 20% to 55%. Aim: The aim of this study is to assess the orthodontic treatment need of school going children of Mysuru district and to assess the perceptive need of orthodontic treatment using mapping of malocclusion. Materials and Methods: A cross-sectional, descriptive survey was conducted among 12-year-old schoolgoing children of Mysuru district. The orthodontic need has been assessed with the Index of Orthodontic Treatment Need (IOTN), and the mapping of malocclusion has been done with the use ArcGIS software version 9.3. With SPSS Version 16, frequency, descriptive, cross-tabulations (Contingency table analysis), and Chi-square test have been applied. Results: Among 409 boys, 163 (39.9%) had a little need, whereas 125 (30.6%) had a moderate need and 121 (29.6%) had a definite need for orthodontic treatment. Among 436 girls, 190 (43.6%) had little, whereas 122 (28%) had moderate need and 124 (28.4%) had definite need for orthodontic treatment (P = 0.53). Moreover, the overall perceptive need for orthodontic treatment need was only 35.6%. Conclusion: The prevalence of malocclusion in the studied sample is 58.2%. There is a general lack of awareness regarding orthodontic treatment as assessed by esthetic component of IOTN index. This study also found that Geographic Information System is a valuable tool for mapping of malocclusion and thus must be considered for studies related to public health.
