ABSTRACT
Abstract The purpose of the study was to investigate the association between single nucleotide polymorphisms (SNPs) in genes encoding estrogen receptors (ESR1 and ESR2, respectively) and delayed tooth emergence (DTE). This cross-sectional study was composed of biological unrelated children of both sexes, age ranging from 11 to 13 years old. DTE was defined when the successor primary tooth was still present in the oral cavity after its exfoliation time or the absence of the permanent tooth emergence into the oral cavity. Children were diagnosed with DTE when they had at least one delayed permanent tooth, according to age of exfoliation of each tooth proposed by The American Dental Association. Genomic DNA from saliva was used to evaluate the SNPs in ESR1 (rs9340799 and rs2234693) and ESR2 (rs1256049 and rs4986938) using Real-Time PCR. Chi-square or Fisher exact tests and Logistic Regression adjusted by age and gender were performed. SNP-SNP interaction was accessed by multifactor dimensionality reduction (MDR) analysis also adjusted by gender and age. The established alpha of this study was 5%. Among 537 included children, 296 (55%) were in the "DTE" group and the 241 (45%) were in the "Control" group. Age and gender were not statistically different among the groups (p>0.05). Genotype distribution of the SNPs rs9340799, rs2234693, rs1256049 and rs4986938 were not associated with DTE (p> 0.05). The models elected by MDR were not statistically significant either.

Conclusions:

The studied SNPs in ESR1 and ESR2 were not associated with permanent DTE.
RESUMO
RESUMO O objetivo do presente estudo foi investigar a associação entre polimorfismos de nucleotídeo único (SNPs) em genes que codificam receptores de estrógeno (ESR1 e ESR2, respectivamente) e o retardo na emergência dentária (DTE). Este estudo transversal foi composto por crianças biológicas não relacionadas de ambos os sexos, com idades entre 11 e 13 anos. O DTE foi definido pela presença do dente decíduo na cavidade bucal após seu tempo e também, quando as crianças apresentaram pelo menos um dente permanente com atraso. O DNA genômico foi usado para avaliar os SNPs em ESR1 (rs9340799 e rs2234693) e ESR2 (rs1256049 e rs4986938) usando PCR em tempo real. Foram realizados testes Qui-quadrado ou exato de Fisher e Regressão Logística ajustados por idade e sexo. A interação SNP-SNP foi acessada pela análise de redução de dimensionalidade multifatorial (MDR), também ajustada por sexo e idade. O alfa de 5% foi estabelecido. Entre 537 crianças incluídas, 296 (55%) estavam no grupo "DTE" e 241 (45%) estavam no grupo "Controle". A idade e o sexo não foram estatisticamente diferentes entre os grupos (p> 0,05). A distribuição de genótipos dos SNPs rs9340799, rs2234693, rs1256049 e rs4986938 não foi associada ao DTE (p> 0,05). Os modelos eleitos pelo MDR também não foram estatisticamente significativos.

Conclusões:

Os SNPs estudados na ESR1 e ESR2 não foram associados ao DTE na dentição permanente.
