Age And Gender Related Distribution Of Patients Undergoing Mandibular Third Molar Extractions- A Retrospective Study

Mandibular third molars are the most common teeth requiring removal for prophylactic or symptomatic reasons. It is important to be able to judge and choose the appropriate surgical approach for treating third molars requiring removal from the oral cavityWhether it needs a trans alveolar or intra alveolar approach. The aim of this study is to determine the frequency of mandibular third molars undergoing intra alveolar extraction and its correlation to age and gender of the patient. This is a single centre retrospective study done from June 2019 – March 2020. The study samples were collected from a pooled patient data of 21000 patients. Based on the set inclusion and exclusion criterias, 1683 patients who underwent extraction of their mandibular third molars were considered. The parameters were examined and processed with relevance to the extracted mandibular third molar teeth on the basis of age and gender of the patient. IBM SPSS Version 20 was used for statistical analysis. Out of a total of 1683 patients considered for mandibular third molar extraction, the most prevalent age group was 21-30 years of age (25.1%). 45% were over 30 years to 50 years of age and interestingly 28.1% were over 50 to 90 years of age. Out of a total of 1682 patients, (51.2%) 862 patients were female patients and (48.8%) 820 patients were male patients More than half the total patients considered required extraction of mandibular third molars on the left side (52.6%). The correlation of age and gender on the mandibular third molar seems statistically insignificant as p=0.926 > 0.05 and p=0.520 > 0.05 respectively. This study concludes to establish that though the predominance of mandibular third molar extractions arise in the age group of 21-30 years, they made only one quarter of the total sample population. The overall majority of patients requiring mandibular third molar extraction among our population were over 30 years of age. Gender predilection was females over males in our population
