PREVALENCE OF CLASS III SKELETAL PATTERN AMONG PATIENTS SEEKING ORTHODONTIC TREATMENT

Abstract

AIM: The aim of the study is found prevalence of class 3 skeletal pattern among patients seeking orthodontic treatmentINTRODUCTION: Class III jaw relationship suggests that the mandible acquired a more mesial position in relation to maxilla or cranial base. Its prevalence varies greatly among and within different races, ethnic groups, and geographic regions. Class III malocclusion has a multifactorial aetiology, which is the expression of a moderate distortion of normal development as a result of interaction between innate factors or genetic hereditary with environmental factors.MATERIALS AND METHODS: A retrospective study was planned with data collection from June 2019 to February 2021 in a university setup. We reviewed the patient’s records and analyzed the data of 86000 patients. The data report includes patient details like gender, age and diagnosis. The records were manually verified by 2 reviewers and the data was tabulated in the Excel sheet followed by statistical analysis using SPSS software (Statistical Product and Service Solutions) in IBM and chi-square tests were performed.RESULTS: Total subject population was 86 in the age range of 11-70 years, males were (67.4%) and females were (32.5%), the majority of patients were in the 11-20 years age group. Mandibular excess was 26.7% highest in skeletal malocclusion among 11-20 years of age group and 40.7% in Males compared to females.CONCLUSION: Within the limitations of our study, it can be concluded that male have higher skeletal class III when compared with females and the most common age group affected by skeletal class III was under the age range of (11-20) years.
