Multiple Supernumerary Molars Mimicking Third Molars: A Rare Dental And Oral Surgery Case Of Seven Wisdom-Like Teeth Extractions

Abstract

Background: Supernumerary teeth are a dental anomaly that can be described using a dental formula, where there is an additional component above what is normally expected within the dental formula. Supernumerary molars, especially those appearing like third molars, are even rarer. In most cases, they occur in the anterior maxillary region.

Objective: To provide a review on supernumeraries that clinically and radiographically imitate third molars in relation to their occurrence, causes, presentation, diagnosis, and management.

Methods: A literature search was performed whereby case reports and studies were surveyed related to cases of supernumerary molars, especially distomolars and paramolars. Clinical and radiological information was gathered from various cases, both maxillary and mandibular.

Conclusion: Supernumerary molars have an incidence that ranges between 0.1% and 3.9% in the permanent dentition, with considerable geographical and morphological variation. Multiple supernumerary molars are found to be present in less than 1% of cases of hyperdontia. Most of the teeth are impacted and asymptomatic and are incidentally noticed during the course of the radiographic exam.

Conclusion: Cases of multiple supernumerary teeth resembling third molars can be classified as a very rare anomaly in dentistry. Accuracy in diagnosing such cases can be achieved using cone beam computed tomography. In cases where early detection and treatment are performed, possible complications such as impaction, crowding, cystic lesions, and adjacent tooth resorption may be avoided.
