DETERMINATION OF SEX USING SIGMOID NOTCH ON THE LEFT SIDE

BACKGROUND The mandibular notch, also known as the sigmoid notch, is a groove in the ramus of the mandible. It is the space bounded anteriorly by the coronoid process and posteriorly by the condylar process. The shape of the sigmoid notch depends on the morphological variations of the coronoid and condylar processes. AIM The aim of the present study is to determine the sex using sigmoid notch on the left side. MATERIALS AND METHOD This study examined 60 digital panoramic radiographs. The length of the mandibular notch was measured from the anterior surface of the head of the mandible to the posterior surface of the coronoid process. Descriptive statistics and the pearson Chi square test was used to analyse the relationship between sex and length of the mandibular notch using SPSS software version 26.0 RESULT The value of mean for the length of sigmoid notch for male was found to be 35.5667 and the value for females was 34.5667. The significance ( p value ) was found to be 0.433 CONCLUSION From the results of the present study, it can be concluded that the length of sigmoid notch was greater in males than in females, but the values were not statistically significant.
