Abstract

In 1942, Stafne first described 35 cases of a radiographic abnormality just anterior to the mandibular angle such abnormalities showed oval or elliptical radiolucencies with welldefined, denser and thicker walls than those seen in odontogenic cysts. These lesions have been described as various terms; Stafne bone defect, mandibular salivary gland inclusion, static bone cavity, latent bone cyst. Usually they are asymptomatic and discovered accidentally from routine radiographic examination with 0.1-0.3% incidence rate and they have a predilection for men between age 50 to 70 and almost unilateral. Though these lesions are defined as well-defined depression in the lingual surface of the body of the mandible, the etiology is still unknown. In the present 2 cases, we experienced unusual bone defect in mandible, only radiographic study confirmed the diagnosis of this anomaly lesion and obviated the surgical intervention.
