Introduction: When a tooth's eruption path is blocked, it is said to be impacted, with the third molar being the most frequently impacted tooth. The third molar's eruption path has been observed to be obstructed by a number of variables, including soft tissue, bone, and neighboring teeth. Previous studies have reported significant differences in dimensions of ramus and third molar impaction, when compared to patients with normal fully erupted third molars. The aim of the current study is to assess the gender related variations in the dimensions of Mandibular ramus and its association with impacted lower third molars.
