Abstract

This paper presents two cases of late developing supernumerary premolars. Case 1 is a female patient with nonsyndromic multiple supernumerary teeth located in the maxillary right premolar-molar region, maxillary left premolar region, and the mandibular right and left premolar regions. In this patient surgical removal of all supernumerary teeth was carried out to avoid complications during orthodontic treatment. Case 2 is a female aged 19 years in whom formation of a mandibular supernumerary premolar was observed which was not present at age 13. The patient was made aware of the supernumerary tooth presence, and periodic radiographic assessment was planned.

Highlights

Excess in the number of teeth which is o en referred to as supernumerary is a developmental anomaly [1]
Orthodontists should be aware that late development of supernumeraries can occur any time in the course of orthodontic treatment or a er its completion
It is not a routine practice to screen for the late development of teeth during or a er orthodontic treatment, possibility of their complications should always be taken into consideration

Summary

Introduction

Excess in the number of teeth which is o en referred to as supernumerary is a developmental anomaly [1]. Supernumerary teeth can be categorized in terms of chronology, topography, and morphology. They can develop before deciduous teeth (predeciduous), simultaneous to permanent teeth or a er them (postpermanent dentition). E majority of supernumeraries in the permanent dentition develop later than normal teeth of that region and are supposed to form postpermanent dentition developing from hyperactivity of dental lamina [11]. In special situations removal of supernumeraries is preferred such as when the teeth need to be aligned orthodontically. F 1: Panoramic radiograph of the patient showing the presence of seven supernumerary premolars. Two further cases of late developing supernumerary premolars and two different approaches for their management are described in this paper
