1. Factors associated with the development of dental defects acquired in the extrauterine environment
Abstract This study aimed to analyze the association of sociodemographic, child health, healthcare service, and access indicators with developmental defects of enamel (DDE) acquired outside the uterus, based on gestational factors. A cohort of births was carried out, and 982 children aged 12 to 30 months were examined. A total of 1,500 women were followed up

2. Demarcated opacity in primary teeth increases the prevalence of molar incisor hypomineralization
Abstract This cross-sectional study aimed to assess the prevalence of molar incisor hypomineralization (MIH) and its relationship with the number of primary teeth with developmental defects of enamel (DDE). A representative population-based sample of 731 schoolchildren was randomly selected from the public school system in Curitiba, Brazil. Schoolchildren ag

4. Amelogenin gene influence on enamel defects of cleft lip and palate patients
The aim of this study was to investigate the occurrence of mutations in the amelogenin gene (AMELX) in patients with cleft lip and palate (CLP) and enamel defects (ED). A total of 165 patients were divided into four groups: with CLP and ED (n=46), with CLP and without ED (n = 34), without CLP and with ED (n = 34), and without CLP or ED (n = 51). Genomic DNA

5. Microabrasion in tooth enamel discoloration defects: three cases with long-term follow-ups
Superficial irregularities and certain intrinsic stains on the dental enamel surfaces can be resolved by enamel microabrasion, however, treatment for such defects need to be confined to the outermost regions of the enamel surface. Dental bleaching and resin-based composite repair are also often useful for certain situations for tooth color corrections. This

6. Influence of deciduous molar hypomineralization on the development of molar-incisor hypomineralizarion
Defects similar to Molar-Incisor Hypomineralization (MIH) in second primary molars can be found in the literature, being recently named Deciduous Molar Hypomineralization (DMH). Researchers have stated that the presence of DMH in primary dentition represents a risk for MIH in permanent teeth. The explanation for this association is probably related to the et

7. Do the Clinical Effects of Enamel Matrix Derivatives in Infrabony Defects Decrease Overtime? A Systematic Review and Meta-Analysis
Revisões sistemáticas prévias tem demonstrado melhores resultados com proteínas derivadas da matriz de esmalte (PDME) em comparação a retalho de espessura total (RET) para o manejo de defeitos periodontais infraósseos (DPI). O objetivo desse estudo foi determinar se essas diferenças variam de acordo com o tempo de acompanhamento e com a qualidade dos

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

9. ESTUDO DOS SISTEMAS CeO2(1-x) :Pr6O11(x); CeO2(1-x):Fe2O3(x) E CeO2(0,95-x): Pr6O11(0,05):Fe2O3(x) PARA APLICAÇÃO COMO PIGMENTOS INORGÂNICOS DE BAIXA TOXICIDADE
This study focused on the Cerium oxide (CeO2) based pigmenting systems, doped with Praseodymium oxide (Pr6O11) and hematite (Fe2O3 iron oxide) synthesized through the solid state reaction (OM oxide mixture) and the Pechini method. Simultaneously, CeO2-Pr6O11-Fe2O3 ternary system pigments were synthesized through OM, with the addition of mineralizers. The sam

10. Prevalence of enamel defects and associated risk factors in both dentitions in preterm and full term born children
OBJECTIVES: The aim of this study was to evaluate the prevalence of enamel defects and their risk factors on primary and permanent dentitions of prematurely born children and full-term born children born at Regional Hospital of Asa Sul, Brasília, DF, Brazil. MATERIAL AND METHODS: Eighty 5-10-year-old children of both genders were examined, being 40 born pre
