VIGUERAS GOMEZ, Olimpia; FERNANDEZ VILLAVICENCIO, Miguel Ángel  and  VILLANUEVA VILCHIS, María del Carmen. Prevalence of supernumerary teeth in children with cleft lip and/or palate. Rev. Odont. Mex [online]. 2015, vol.19, n.2, pp.81-88. ISSN 1870-199X.

The aim of the present study was to establish the prevalence of supernumerary teeth in children afflicted with cleft lip and/ or palate. A cross-sectioned study was conducted on 608 orthopantomographies from pediatric patients who attended the stomatology and orthodontics clinics of the <<Dr. Manuel Gea González>> Hospital in Mexico City. Cases in reviewed files revealed a ratio of 53.9% male and 46.1% female, with 7.2 year age average. Prevalence of supernumerary teeth was found to be 15.4%: 19.8% in males and 9.1% in females. 97% of all supernumerary teeth were found on the side of the cleft. Main location was the lateral incisor region (84.8%). Most cases occurred in primary dentition (51.5%). These patients experienced high prevalence of supernumerary teeth. Prevalence was observed to be higher in male patients, in primary dentition and the lateral incisor region.

Keywords : Cleft lip and palate; dental anomalies; supernumerary teeth.
