Maxillary Distomolar Associated with Dentigerous Cyst: An Unusual Entity

Abstract

Supernumerary teeth may be encountered as an incidental finding on a radiograph. When impacted, they may be associated with clinical signs related to different problems such as failure of eruption, teeth displacement, root resorption or cystic lesions. They may occur in primary and permanent dentition, in both the maxilla and mandible and can be single or multiple in patients with syndromes. Mesiodens is the most commonly impacted tooth and appears between the central maxillary incisors in pediatric ages. Supernumerary teeth distal to the third molar are rare, usually impacted and referred to as a distomolar. A 46-year-old male consulted with the main complaint of pain on the left side of the maxilla. A panoramic radiograph revealed a right impacted maxillary fourth molar located posterior to the third molar associated with a pericoronal radiolucency. The supernumerary tooth was removed surgically under local anesthesia and the pericoronal lesion enucleated. Histopathological examination was consistent with the diagnosis of a dentigerous cyst associated with an impacted distomolar. Healing was uneventful, and the patients remained asymptomatic. The occurrence of a maxillary distomolar is rare and even rarer the association with a dentigerous cyst.

Oral manifestations and their management in Kindler's syndrome: An oral clinician's perspective

“…Distomolars can cause complications like impaction of teeth, root resorption, caries, infection, cysts, and tumors. 10 Distomolar in Case 1 was associated with impacted mandibular third molar is a novel finding. nutritional status, diet, and oral intake, as well as genetic counseling, was advised.…”

“…Distomolars are rare supernumerary teeth more commonly found in the maxilla, with a prevalence ranging from 0.32%–2.1% in non‐syndromic patients. Distomolars can cause complications like impaction of teeth, root resorption, caries, infection, cysts, and tumors 10 . Distomolar in Case 1 was associated with impacted mandibular third molar is a novel finding.…”

“…It is located in buccal or palatal next to a molar and most often occurs in the interproximal spaces of the upper second and third molars [8][9][10][11]. Distomolars are defined as supernumerary teeth that develop distally from the third molar [12,13].…”

Dentigerous Cysts with Diverse Radiological Presentation Highlighting Diagnostic Challenges

“…A dentigerous cyst (DC), also known as a follicular cyst, is a cyst of non-inflammatory odontogenic origin that develops from the pericoronal tissue (dental sac or dental follicle) of an impacted tooth, either permanent or deciduous or supernumerary [ 1 , 2 , 3 , 4 , 5 , 6 ]. Several factors have been investigated and are known to play an important role in tooth eruption [ 7 ].…”
