Dental anomalies of form and number in primary dentition in a Mexican population

Abstract

Abstract: To determine the frequency and distributionof dental anomalies of shape and numberin primary dentition.
 Methods: The study is retro-prolective, crosssectionaland descriptive. The sample was probabilistic,stratified for convenience by gender. Theclinical record of 1,568 patients was reviewed.These patients attended the Clinic of PediatricDentistry of FEBUAP during the period of 2012-2014, only 720 records of patients were includedin the study (321 girls and 399 boys) between theages of 1-10 years old, who provided complete,crisp radiographic studies with the presence ofdental anomalies of shape or number, the studywas divided into active and inactive patients.For inactive patients, photographs of x-rays withdental anomalies of shape and/or number weretaken. For cases with active patients, an interviewwith one of the parents was conducted andauthorization with informed consent was requested,also the child agreed to do a clinical examinationand take intraoral photographs.
 Results:A total of 63 children had anomalies (17girls and 46 boys). The total prevalence of dentalanomalies was 9%, of which 3.1% were (fusedand geminated teeth), 1.1% (agenesis) and 1.9%(supernumerary), 1.3% (supernumerary roots),0.27% (macrodontia), 0.11% (microdontia), andfinally 0.27% corresponded to (talon cusp).
 Conclusions: Although the prevalence of theseanomalies is not high, it is important to do a routineradiographic examination for early diagnosisand accordingly apply the correct preventivemeasures to establish the best treatment plan.
