Perinatal factors associated with developmental defects of enamel in primary teeth: a case-control study

Abstract

The present study was designed to evaluate associations between developmental defects of enamel (DDE) in the primary dentition and aspects related to mothers and preschoolers in the city of Diamantina, Brazil. A case-control study was carried out involving children aged three to five years. The case group was composed of 104 children with at least one dental surface affected by DDE. The control group comprised 105 children without DDE, matched for gender and age. The diagnosis of enamel defects was performed using the Developmental Defects of Enamel Index. Information was collected through interviews investigating socio-demographic aspects, gestation, birth weight, prematurity and breastfeeding. Simple and multiple regression analyses were performed, providing unadjusted and adjusted prevalence ratios (Poisson regression). DDE were more prevalent among children who had not been breastfed (PR = 1.57; 95% CI: 1.1-2.2) and those whose mothers were under 24 years of age at the birth of the child (PR = 1.41; 95% CI: 1.1-1.9). The prevalence of DDE in the primary dentition was higher among children who had not been breastfed and those whose mothers were under 24 years of age at the birth of the child.

Defeitos de esmalte não fluoróticos em crianças: aspectos clínicos e epidemiológicos

“…Em relação ao baixo peso do recém--nascido, alguns estudos observaram que os defeitos de esmalte mais encontrados foram as opacidades demarcadas nos incisivos e molares 16,36,37 .…”

“…Crianças não amamentadas foram 3,2 vezes mais suscetíveis a serem afetadas por DDE quando comparadas com aquelas que foram amamentadas 5,37,38 . A ausência de amamentação é um importante fator predisponente ao aparecimento de DDE, porque faz com que a criança seja privada de substâncias nutricionais, como a vitamina D, necessárias para o seu desenvolvimento e, consequentemente, para a formação do esmalte 8 .…”

“…O leite materno é o primeiro veículo de oferta de nutrientes para o indivíduo, entretanto, nem sempre garante uma nutrição completa do neonato. A deficiência de cálcio está relacionada à hipoplasia do esmalte em crianças nascidas prematuramente abaixo do peso normal (menos de 2.500 gramas) 37,38 .…”

Preterm Birth and Breastfeeding Are Related to Gastroesophageal Reflux Onset: An Observational Cross-Sectional Study

“…International Publisher demonstrated that defects of enamel are deeply influenced by etiological factors that may be influencing already before the birth. 4 In preterm children, teeth are often more susceptible to caries and such alterations are often linked to an early onset GER: the severe hypocalcification of the dental tissues and the rapid onset of carious lesions strongly affect the esthetics of patients, with a negative impact also on social and psychological aspects. 5,6 In the light of this framework, our study has been aimed to investigate about the relationship between pediatric oral and systemic pathologies coexisting with preterm birth condition.…”

Hipomineralização molar incisivo (MIH) : uma correlação de fatores possivelmente desencadeantes

“…As interferências ocorridas durante a formação do esmalte são permanentemente registradas. Os defeitos de esmalte são definidos como distúrbios na formação e mineralização dos tecidos duros durante a odontogênese (21). As influências no desenvolvimento dentário podem afetar quantitativa e qualitativamente o desenvolvimento tanto do esmalte quanto da dentina (22,109 superfície lisa e espessura normal de esmalte (25,26).…”
