Abstract

ABSTRACT A supernumerary tooth is one that is additional. The diagnosis is usually made by clinical exam and routine radiographs, and the majority of such teeth are impacted and asymptomatic, without affect others teeth. The supernumerary teeth, can occur included or impacted. An early diagnosis is important in order to implement a suitable plan of treatment and prevent such complications. Ectopic inclusions occur at about 1% of the general population and might be present at many diverse localizations. In this article the authors review the literature around the ectopic inclusions and report a case of an intranasal ectopic supernumerary inclusion. The prophylactic surgical removal of the supernumerary teeth is generally the treatment of choice.

Highlights

Supernumerary teeth are developmental alterations with regard to the number of teeth, where one or more extra teeth are formed
The diagnosis is commonly performed via routine X-rays[1]
On account of the rarity of the following reported case, and in the absence of similar cases in the literature reviewed, we present the case report of a cone-shaped supernumerary tooth embedded in the root of the zygomatic arch, where the treatment of choice was surgical removal

Summary

INTRODUCTION

Supernumerary teeth are developmental alterations with regard to the number of teeth, where one or more extra teeth are formed. The cause is still uncertain, though a number of hypotheses have been proposed, though they have not yet amassed sufficient material to prove the origin of these extra teeth Of these theories, the most widely accepted is that of the hyperactivity of the dental lamina in the initiation stage, resulting in a new tooth bud. The effects caused by the presence of extra teeth range from the non-eruption of teeth in the normal series, malposition, diastemas, development of dentigerous cysts, headaches, paresthesia, local disorders and resorption of the adjacent teeth They may cause several alterations in the development of occlusion, including complications such as crowding, impacted permanent teeth, root resorption, midline diastemas, eruption in the nasal cavity as well as the formation of periapical or follicular cysts[1,4]. Clinical judgment or the patient’s strength may contraindicate surgical removal, in which case regular radiographic checks are mandatory to prevent complications[1]
