The objective of this research is to determine the prevalence of dental development abnormalities in number and position in patients aged 5 to 15 years with unilateral cleft lip and palate, treated at the Guillermo Almenara Irigoyen Hospital, Lima, 2017. This was an observational, retrospective, cross-sectional, and descriptive study. The population consisted of 44 panoramic radiographs taken from February 2016 to April 2017. The sample was probabilistic and was calculated using a formula, resulting in 40 panoramic radiographs. The collected data included: sex, age, location of the unilateral cleft lip and palate, and dental development abnormalities in number and position. The data entry and statistical analysis were performed using SPSS version 21. The results showed that 100% of patients with unilateral cleft lip and palate had dental development abnormalities. It was observed that the prevalence was higher in males (77.5%) and that the left side was the most prevalent location for the unilateral cleft lip and palate (52.5%). The study concluded that every patient with unilateral cleft lip and palate presents some form of dental development abnormality.

Cleft Lip and Palate (CLAP) is one of the most common congenital malformations, resulting from a disruption in the fusion of the tissues that form the upper lip and palate during embryonic development. This study aimed to determine the frequency of congenital dental anomalies related to variations in number, size, and shape in patients with cleft lip and palate treated at the Hospital Nacional Docente Madre Niño San Bartolomé, Peru, in 2015. The study was conducted with 52 patients aged 1 to 7 years with cleft lip and palate from June to November 2015, using clinical observation, panoramic radiographs, and medical history. It was a prospective, cross-sectional, descriptive, and observational study. The results showed that 19.2% of the sample had an incomplete unilateral left cleft, with a male predominance at 13.5%. The most common dental anomaly was dental agenesis, at 63.5%, followed by microdontia at 26.9%, and 30.8% of patients had dental alterations. Regarding cleft type, 15.4% had incomplete unilateral left and right clefts associated with dental agenesis, 9.6% had incomplete unilateral left clefts associated with microdontia, and 7.7% had bilateral clefts with shape alteration. It was concluded that there is a significant difference when associating the number of dental anomalies with cleft type, where dental agenesis was most prevalent in complete unilateral right and left clefts.
