Five parapremolars in a non-syndromic patient: A case report

Abstract

Supernumerary teeth or hyperdontia are additional or an excessive number of teeth present in normal deciduous or permanent dentition. The prevalence of supernumerary teeth is between 0.1 and 3.8% in permanent dentition and between 0.3 and 0.8% in deciduous dentition. In Sabah, the prevalence of supernumerary teeth is 10.32% among orthodontic patients. The condition is more common in male patients. A case report involved a fit and healthy 19-year-old male student who presented with multiple supernumeraries. Upon clinical examination, there were three erupted supernumeraries on the bilateral mandibular premolar region, and additional two impacted supernumeraries being discovered after further radiographic investigation. This anomaly was found during an annual dental school checkup program. The patient had congenital absence of the lower left third molar. Primary dental care was carried out such as filling for carious teeth, scaling, oral hygiene reinforcement and regular monitoring. The patient declined any other dental treatment options such as extraction of the non-functioning supernumerary parapremolar teeth, or orthodontic treatment to improve his malocclusion. Currently, the patient is under oral hygiene maintenance with regular dental follow-ups. In a nutshell, the importance of regular dental follow-ups and review is crucial to monitor any signs and symptoms of pathology such as cystic formation of unerupted supernumeraries. Reinforcement of oral hygiene and caries risk assessment should be carried out during reviews to improve and maintain the patient’s quality of life.
