The study also provided comprehensive morphometric data on the retromolar canals (RMCs) and foramina (RMFs) observed in the study population. Key measurements included the distance from the buccal and lingual cortices to the RMCs, the distance from the mandibular foramen to the RMC origin, and the distances from the RMF to the mandibular canal and adjacent molars. These detailed spatial relationships were analyzed across different age groups and between genders. The data revealed trends, such as decreasing buccal distances and increasing lingual distances with advancing age.
