Prevalence of ectopic eruption and intercanine distance in children aged 6 to 12 years. Cycle 2019-2020

Abstract

The development of permanent teeth and their eruption is of utmost clinical importance, it is also useful in anthropology, demography, forensic medicine and paleontology studies. When the eruption sequence and the mechanisms are not adequate, it causes an ectopic eruption that must be detected in time in order to avoid damage to the occlusion that affects the aesthetics, function, self-esteem and quality of life of the child. Objective: To identify the prevalence of ectopic eruption and intercanine distance in children aged 6 to 12 years. Methodology: An epidemiological, cross-sectional, descriptive study was carried out in order to clinically detect this eruption anomaly. The selection of the sample was 77 children who met the selection criteria, during the 2019-2020 school year. In a rural primary school in a municipality of Zacatecas, the intercanine distance measurements were subsequently carried out with the help of a Vernier, after calibration and informed consent, the information was processed through the statistical program SPSS V 24 and Excel. Results: The prevalence of ectopic eruption was 22%, the female gender the most frequent age was 7 years. The average upper intercanine distance was 26.76mm * - and in the lower jaw it was 33.4mm + _: the tooth that presented the most frequent ectopic eruption was No. 22, the least frequent was 32 and 15. It was observed a decrease in the intercanine distance 26.7mm. In children with multiple ectopic eruption, the intercanine distance decreased, the lower lateral incisors were detected between the teeth with the highest prevalence of ectopic eruption. Conclusions: It is necessary to intervene in the early stages in order to avoid the installation of malocclusion and costly, long and more difficult orthodontic treatments. Prevention is better than cure.
