Abstract
BackgroundTo establish the prevalence of supernumerary canines (SNC) in a sector of the population of Madrid (Spain), as well possible complications associated with this unusual developmental variation.Material and MethodsThis observational study was performed between 2005 and 2017, among 21,615 patients seeking dental treatment at the Faculty of Dentistry, Complutense University of Madrid (Spain), and at the Virgen de la Paloma Hospital, Madrid (Spain); 22 patients with 26 SNCs were diagnosed. These 22 patients underwent clinical and radiological exploration, registering patient data.ResultsSNCs presented a prevalence of 0.10% of the study population. The supernumerary teeth (SNT) were located in the upper maxilla more frequently (61.54%) than the mandible (38.46%). 69.23% were found to be impacted, also causing the impaction of the permanent canine in 53.85% of these cases. In 15.38%, follicular expansion > 3mm was observed. SNCs were associated with other SNT in only four patients.ConclusionsDespite of the fact that the SNCs are usually diagnosed casually in the course of radiological exploration, in the present study over half of them (53.85%) caused impaction of the permanent canine. Early diagnosis allows optimal patient management and treatment planning, with intervention at an appropriate time to prevent complications in development and so reduce later treatment need.

Highlights
Hyperdontia, hypergenesis or the presence of supernumerary teeth (SNT) is defined as the existence of teeth in excess of normal dentition [1]
The present study set out to determine the prevalence of supernumerary canines (SNCs) in a sector of the population of Madrid, as well as the possible complications associated with hypergenetic canines
Imagebased diagnosis established whether location was maxillary or mandibular, the morphology of the SNC, the state of the follicular sac, and any association with other SNT
