B Background: sex determination can be performed through bone morphology. however, morphological methods are often subjective. this limitation can be addressed by using measurement-based approaches, such as morphometric analysis. among various skeletal elements, the mandible is considered a reliable bone for sex identification. radiographic morphometry, particularly using panoramic radiographs allows for accurate assessment with the mandibular ramus serving as one of the key parameters for distinguishing between sexes. objective: this study aims to determine whether there’s a difference in mandibular ramus width between males and females through radimorphometric analysis. methods: this study used 160 panoramic radiographs consisting of 80 male radiographs and 80 female radiographs from the digital database of the radiology department in rsgm-p faculty of dentistry, trisakti university from january 2024 to may 2025, which met the inclusion and exclusion criteria. the obtained data were analyzed using spss by conducting descriptive analysis, a normality test using the kolmogorov-smirnov test, and a non-parametric test using the mann-whitney test. results: based on the kolmogorov-smirnov test, the distribution of data in females was not normal, with a significance value of 0.031, which did not meet the criteria of p ≥ 0.05. the mann-whitney test showed a significance value of < 0.001 (p ≤ 0.05). conclusion: the results of this study are in accordance with the hypothesis that there’s a difference in the width of the mandibular ramus between males and females through radiomorphometric analysis, in which the width of the mandibular ramus in males are greater than in females.
