چکیده
PURPOSE The aim of this study was to analyze the presence of the RMF in mandibles, considering gender and ethnic group. The RMC was also analyzed using periapical radiography. METHODS Eighty-six mandibles from adult individuals of both sexes, of white and black skin colours were analyzed. The presence of RMF (bilateral or unilateral) was observed, with the side and the number of foramina in each hemimandible. Five mandibles were selected for RMC evaluation by periapical radiography. RESULTS We observed at least 1 RMF in 16 mandibles out of a total of 86 (18.60%) and in 21 out of 172 sides (12.20%). The percentages were 27% in black individuals, 15.6% in white individuals, 23.8% in females and 13.8% in males. CONCLUSIONS The RMF is a reasonably frequent anatomical variation and shows no differences between sexes or ethnic group, can be unilateral or bilateral and presents no side preference. The RMC presents different types of course and can even establish contact with the alveolar cortical, which might further complicate surgical and anaesthetic procedures in this region.

Occurrence of the Retromolar Foramen in Dry Mandibles of South-Eastern Part of India: A Morphological Study with Review of the Literature
The retromolar foramen (RMF) is a rare anatomical structure situated in the retromolar fossa behind the third molar tooth. When it is present, the foramen is connected with the mandibular canal and is believed to transmit neurovascular structures that provide accessory source to the mandibular molars and the buccal area. Reports from the literature show that the presence of RMF could pose a cha...

INTRODUCTION The retromolar canal is an anatomic structure of the mandible with clinical importance. This canal branches off from the mandibular canal behind the third molar and travels to the retromolar foramen in the retromolar fossa. The retromolar canal might conduct accessory innervation to the mandibular molars or contain an aberrant buccal nerve. METHODS Patients referred for panoramic...

Background. The retromolar canal (RMC) is an anatomical variation that can cause complications in dental procedures. Method. The RMC was evaluated according to age, sex, and presence of accessory mandibular canal and accessory mental foramen, on both sides in 500 panoramic radiographs, belonging to individuals at the age of 7 to 20 years. The associations of interest were studied through Fisher...

A retromolar canal is an anatomical variation in the mandible. As it includes the neurovascular bundle, local anesthetic insufficiency can occur, and an injury of the retromolar canal during dental surgery in the mandible may result in excessive bleeding, paresthesia, and traumatic neuroma. Using imaging analysis software, we evaluated the cone-beam computed tomography (CT) images of two Korean...
