Abstract
Aim and Objective: The current finding is about to observe the presence of retromolar foramen (RMF ) bilaterally, on the right and on the left side and to look into the prevalance of RMF on retromolar triangle in cadaveric dry human mandible.
Materials and Methods: In this study all available 72 dry, fully ossified adult mandibles from the department of Anatomy, Shri Guru Ram Rai Institute of Medical and Health Sciences, Dehradun, Uttarakhand northernregion of India had been covered barring gender and age distinction. The mandibles were observed for the presence and absence of retromolar foramen.
Result: The retromolar foramen located at 24 (33.3%) of 72 mandibles of which 7 on the right side (9.7%),11 on the left side (15.2%),and 6 bilaterally (8%). From above statistics it is found that Retromolar Foramen located greater on Left side than the right side.
Conclusion: The knowledge about variations of the retromolar foramen is necessary for practising surgeons, it has been not properly mentioned in all textbooks so on this basis the presentstudy is achieved to consider the incidence of the retromolar foramen and its location in human mandibles.
Keyword: Dry adult mandible, Retro molar fossa, and Retro molar foramen.
