DIAZ DEL OLMO MOREY, CARLOS ENRIQUE; ARISPE ALBURQUEQUE, CLAUDIA MILAGROS; DIAZ DEL OLMO MOREY, FERNANDO LUIS and BENITES CASTILLO, SANTIAGO. Dental anomalies of number in Peruvian pediatric patients during the years 2011-2020. Salud, Barranquilla [online]. 2023, vol.39, n.2, pp.465-476. Epub Mar 15, 2024. ISSN 0120-5552. https://doi.org/10.14482/sun.39.02.346.546.
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 analytical 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=0.001). 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=0.001).
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.
