Mandibular buccal bifurcation cyst treatment: report of two cases and literature review

The mandibular bifurcation cyst is an uncommon lesion that was first described by Stoneman and Worth in 1983. It is a site and age-specific lesion affecting the first or second permanent mandibular molar in children between 6 and 13 years old. Even if the clinical and radiological signs are well defined, this lesion can be misdiagnosed in particular with forms which would have a spontaneous resolution. The patient care is less well defined, the range of treatments being rather wide, from the simple follow-up to the extraction of the involved tooth. Both two clinical cases presented will illustrate the diagnostic criterias associated to the buccal bifurcation cyst. The etiopathogenesis and the therapeutic decision criterias will be discussed through a literature review
