Of the several pathologies that affect the oral cavity, malocclusion is the third most important problem in the world population. It not only affects the appearance but also affects the periodontal health. The aim of the study was to assess the association between periodontal health and different angle’s malocclusion. This retrospective study was conducted among outpatients reported to Saveetha Dental College and Hospitals, Chennai from June 2019 to March 2020. The study consisted of 300 patients (50 patients in each group). Patients were segregated into six groups based on Angle’s classification (Group 1: Class I; Group 2: Class II division 1; Group 3: Class II division 2; Group 4: Class II subdivision; Group 5: Class III; Group 6: Class III subdivision). The type of molar relationship was then correlated with the periodontal status. Out of 300 patients, the prevalence of gingivitis (92%) was higher among Class II subdivision patients and the prevalence of periodontitis (22%) was higher among Class II division patients. Also, the correlation between different types of malocclusion and periodontal health was assessed and found to be statistically not significant (p=0.306).

Supraeruption can be defined as a phenomenon whereby the crown of the tooth erupts beyond the occlusal plane. Occlusal plane disruption can result in improper distribution of occlusal force resulting in trauma from occlusion. Supraeruption of teeth with opposing missing teeth will lead to migration of the gingival margin and increase in the crown height. The aim of this study was to determine the association of supraeruption with relation to opposing missing teeth. A retrospective study was done in an institutional setting to study the association of supraeruption and opposing missing dentition. Among patients who have visited the dental facility, the records of the patients were obtained from a given time period of June 2019 to April 2020. The patients case sheets were analysed using parameters which are supraerupted teeth (upper posteriors & lower posteriors), opposing missing (upper posterior, lower posterior, & NIL) and gender. The data was sorted and was tabulated in excel. Analysis of data was done in SPSS software. The association of supraerupted teeth and its correlation to opposing missing teeth was evaluated. Total of 153 supraerupted teeth were noted. It was found most of the supraerupted upper posteriors had missing lower posteriors (81.05%) whereas some had no missing opposing teeth (12.42%). In all supra erupted lower posteriors, the upper posteriors were missing (6.54%). .Significant association between supraeruption and opposing missing teeth.

Oral habits such as finger and thumb sucking, lip sucking, mouth breathing when used excessively or continuously can lead to poor dental health or malocclusion.The use of habit breaking appliances will restrict oral habits and prevent malocclusion. The aim of this study was to evaluate the prevalence, gender and age distribution of usage of habit breaking appliances in the management of parafunctional oral habits. 44,100 patient records were reviewed from June 2019 to March 2020. Patients who had undergone treatment with habit breaking appliances were selected and their treatment details were obtained from the patient records to obtain the prevalence. Details on habits and habit breaking appliances were also noted and tabulated in excel and imported to SPSS. Descriptive statistics and chi square test were done. There was a statistical significance between age and habits breaking appliances (p<0.05). No statistical significance was noted between gender and appliance usage. Treatment with habit breaking appliances was more prevalent in males. Thumb sucking was the most prevalent habit among the studied population and tongue crib was the preferred choice of appliance.
