Abstract

Objective: To determine the prevalence and association of number dental anomalies according to sex, type and location in the oral cavity in a Peruvian pediatric population during the years 2011 to 2020.

Materials and methods: Quantitative, retrospective and correlational study carried out in a universe of 8,000 panoramic radiographs of pediatric patients taken in a dental imaging diagnostic center in the city of Lima-Peru. There were 614 radiographic images selected by simple random sampling.

Results: Anomalies of number 13.5% of cases with 7.3% of agenesis and 6.2% of supernumeraries, 11.8% in women and 15.7% in men being 8.6% and 4.4% in the upper and lower jaw, respectively, with a statistically significant difference between both jaws (p=0.000). Agenesis was 7.5% in men and 7.2% in women, and supernumeraries were 8.2% in men and 4.6% in women. 51.1% of agenesis were in the lower jaw and 44.4% in the upper jaw. 86.8% of supernumeraries were in the upper jaw and 10.5% in the lower jaw, with a statistically significant difference between both locations (p=0.000).

Conclusions: The prevalence of dental anomalies of number is within what is reported in the literature without presenting an association with sex. Most frequently located in the upper jaw with a statistically significant difference between both jaws. The supernumerary pieces present a statistically significant relationship with their location in the upper jaw.
