What is retromolar region?
The retromolar space or retromolar gap is a space at the rear of the mandible, between the back of the last molar and the anterior edge of the ascending ramus where it crosses the alveolar margin.
Where is the retromolar region?
The retromolar trigone (rTR) is a triangular region covered by gingival mucosa and is positioned between the lower third molar and the ascending ramus of the mandible. This anatomic area is critical from an oncologic point of view due to its spatial relationship with the surrounding structures.
What is the function of retromolar Trigone?
The mucosa covering the Retromolar Trigone is rigid as it is tightly adherent to the underlying alveolar bone. This is what is said to help malignant tumors infiltrate the mandible in a short period if time in the early stages. The rTR is known as the anatomic crossroad where muscular and nervous components converge.
What is the oral region?
It includes the lips, the lining inside the cheeks and lips, the front two thirds of the tongue, the upper and lower gums, the floor of the mouth under the tongue, the bony roof of the mouth, and the small area behind the wisdom teeth.
What is retromolar mucosa?
The retromolar trigone, sometimes called the retromolar fossa, is an oral cavity subsite that consists of the mucosa posterior to the last mandibular molar. It is roughly triangular shaped and extends superiorly towards the maxilla along the anterior surface of the mandible.
What is the retromolar triangle?
Description. The retromolar triangle, retromolar fossa, retromolar space or retromolar gap is a space at the rear of a mandible, between the back of the last molar and the anterior edge of the ascending ramus where it crosses the alveolar margin.
What is right retromolar Trigone?
The retromolar trigone (RMT) is a small triangular subsite of the oral cavity. It is the portion of mucosa that lies behind the third molar tooth covering the anterior ramus of the mandible.
What are the functions of the oral region?
Overview. The oral cavity represents the first part of the digestive tube. Its primary function is to serve as the entrance of the alimentary tract and to initiate the digestive process by salivation and propulsion of the alimentary bolus into the pharynx.
Is the tongue?

What is a Ramus artery?
The ramus intermedius is a variant coronary artery resulting from trifurcation of the left main coronary artery 1. It is present in ~20% (range 15-30%) 2-3 of the population.
What is the definition of Ramus?
Definition of ramus : a projecting part, elongated process, or branch: such as. a : the posterior more or less vertical part on each side of the lower jaw that articulates with the skull.
What are the anatomical terms for the retromolar area?
The anatomical terms of retromolar area, papilla, tubercle, trigone, triangle, fossa, dimple, are often confused in the literature. This article specifies the terminology as well as the anatomical organization of …
What is the function of the retromolar foramen?
The retromolar foramen (RMF) and retromolar canal (RMC) are the anatomical structures of the mandible located in retromolar fossa behind the third molar tooth. This foramen and canal contain neurovascular structures which provide accessory/additional innervation to the mandibular molars and the buccal area.
Where is the retromolar fossa located?
The RMF is an inconstant foramen situated in the central portion of the retromolar fossa which is bounded by the anterior border of ramus of the mandible and temporal crest ( Fig. 1 ).
What type of bifid is the retromolar nerve?
The retromolar nerve, which runs through the RMC, is a type 1 bifidity of the mandibular canal. The investigations of the RMF and RMC have been performed by dry mandible studies, the panoramic radiograph (PAN), computed tomography (CT), and the cone beam computed tomography (CBCT) studies.
