Ectopic Compound Odontoma in the Buccal Mucosa: Report of a Rare Case

Abstract

Eruption of tooth into extraosseous locations is an extremely rare condition. We report a case of a six-year-old girl child with tooth-like structure erupting from the right buccal mucosa. Clinical, radiographic, and histopathologic examination suggested the diagnosis of compound odontoma. Very few cases have been reported so far, where tooth has been located completely in the soft tissue and a variety of names have been used for that condition. A brief review of the literature and the ambiguity in naming the situation is discussed.

Compound odontoma associated to permanent teeth impaction in jaw

“…Based on clinical and radiographic evaluation it was established the clinical initial diagnosis of odontoma. The patient received outpatient surgical indication under local anesthesia [3][4][5] .…”

“…Between the tissues may be observed enamel, cementum, small spaces containing pulp tissue and epithelial rest 3,4 . The Compound Odontoma is formed by all tissues of normal tooth neatly arranged 5 .…”

“…Odontomas have slow growth and are not aggressive; most are asymptomatic, being diagnosed in routine radiographs with a radiopaque aspect [1][2][3][4][5][6] . The differential diagnosis of odontoma may be presented in the initial and intermediate stages, such as ossifying fibroma, periapical cementum dysplasia, adenomatoid odontogenic tumor and epithelial odontogenic calcifying cyst 8 .…”

“…The odontome shows a slow growth exceeding the tooth size and sometimes it can cause expansion of the cortical bone. 7 …”

Impacted Mandibular Premolar Concomitant with Compound–Complex Odontome in a 13-year-old Girl: A Case Report

“…Compound odontoma epitomizes itself as aberrations with the presence of all types of dental tissues and showing an orderly distribution in the form of tooth-like structures; whereas complex odontoma describes itself as aberrations in which the presence of some or all dental tissues and in a disorganized distribution. 8 Based on morphology, compound odontoma is further classified into denticular, particulate, and denticuloparticulate. Denticular variety has two or more separate denticles, each resembling a tooth; particulate variety has two or more separate masses of particles with dental tissues abnormally arranged; denticuloparticulate variety has denticles and particles present side by side.…”
