Buccal Bifurcation Cyst

The buccal bifurcation cyst was first identified and described in 1983 by Worth and Stoneman. This lesion is present on a specific location i.e., buccal surface of the mandibular first and second molar. It mostly occurs in the children of age 5 to 10. This infection is usually associated with pain. It is also called as a mandibular infected buccal cyst and paradental cyst.

There are some important radiographic features of this cyst:

LOCATION : Its region is furcation and mostly occurs in the permanent mandibular first molar.
EDGE : Its edge is well defined and well localized.
SHAPE : Oval or round.
INTERNAL : Unilocular and radiolucent.
NUMBER : Mostly single.

This cyst is associated with the vital tooth and when occurs it is very clear to identify as the lingual cusps appear higher than the buccal cusps due to tilting. When it enlarges, it resorbs or displaces the adjacent teeth. It may cause swelling of buccal cortex , pain and infection.

The former treatments of this cyst was extraction or root canal of the infected tooth. The current treatments are with the preservation of the infected tooth. There are 44 cases of the treatment of this cyst that are done only by enucleation without removal of involved tooth.
