1. Relation of Dental Anomalies with Occlusal Alterations in the Pediatric Patients
Abstract Objective: To identify the dental anomalies that can modify the occlusal characteristics and their distribution in these occlusal alterations in the skeletal patterns of children. Material and Methods: We analyzed charts, panoramic and periapical radiographs of children aged 5 to 12 years from 2009 to 2012. The facial pattern was evaluated through

2. Diversity of clinical, radiographic and genealogical findings in 41 families with amelogenesis imperfecta
Abstract Amelogenesis imperfecta (AI) is a group of enamel development disorders that alter the structure and chemical composition of the tissue. There is great variability in the clinical presentation; according to Witkop, AI can be categorized into 14 subtypes, which makes its diagnosis extremely complex. Objective: This study aimed to describe and determ

3. Immediate Desensitization in Teeth Affected by Amelogenesis Imperfecta
Resumo O objetivo deste estudo foi descrever uma técnica de dessensibilização dental imediata, usando o adesivo universal em paciente adolescente diagnosticado com amelogênese imperfeita. O paciente afetado pela amelogênese imperfeita apresentava dentes extremamente sensíveis, e foi submetido a aplicações de adesivo universal para dessensibilizar os

4. Clinical and molecular analysis of the enamelin gene ENAM in Colombian families with autosomal dominant amelogenesis imperfecta
In this study, we analyzed the phenotype, clinical characteristics and presence of mutations in the enamelin gene ENAM in five Colombian families with autosomal dominant amelogenesis imperfecta (ADAI). 22 individuals (15 affected and seven unaffected) belonging to five Colombian families with ADAI and eight individuals (three affected and five unaffected) be

5. Amelogenesis Imperfecta, hypoplastic type associated with some dental abnormalities: a case report
Amelogenesis imperfecta (AI) é uma desordem hereditária que expressa um grupo de condições que causam alterações de desenvolvimento na estrutura do esmalte. A AI é um problema grave que compromete a qualidade de vida relacionada à saúde bucal e causa alguns problemas psicológicos. O tratamento de pacientes com AI pode melhorar sua qualidade de vida

6. Morphological analysis of the enamel organ in rats treated with fluoxetine
PURPOSE: Previous studies have evaluated the presence of serotonin in the dental epithelia and mesenchyme during odontogenesis, suggesting its participation in tooth development. MATERIALS AND METHODS: Here, we used fluoxetine, a selective serotonin re-uptake inhibitor, at a dose of 10 mg/kg, administered for 20 days during pregnancy in 12 Wistar rats to exa

7. Efeito do fluor sobre a matriz organica do esmalte dentario de camundongos / Fluoride effect in the secretory-stage enamel organic extracellular matrix of mice
Dental fluorosis is characterized by alterations in the aspect of mature enamel due to hypomineralization, it is caused by chronic ingestion of fluoride during tooth development. Fluoride seems to influence on formation of enamel organic matrix. Previous studies have shown that the organic extracellular matrix of the enamel secretory phase is birefringent, e

8. Efeito da radiação ionizante na formação da matriz organica do esmalte dentario / Effect of ionizing radiation in dental enamel organic matrix formation
The aim of this study was to evaluate the dental eruption rate, the organic enamel matrix birefringence, the odontogenic tissue morphology and the ultrastructure of secretory ameloblasts in incisor of rats submitted to high radiation doses. For this purpose, sixty male rats were used, the first thirty divided into three experimental groups: Control, 15Gy and

9. Desenvolvimento osseo e dentario : aspectos biologicos, bioquimicos e moleculares da remodelação da matriz extracelular regulada pelas metaloproteinases de matriz e seus inibidores / Dental and bone development : biology, biochemistry, and molecular aspects of the matrix metalloproteinases and their inhibitors during extracellular matrix remodeling
Our objective was to analyse the spatial-temporal distribution of MMP-2, MMP-9, TIMP-1, TIMP-2 and RECK during development of mineralized tissue (bone, enamel, and dentine) in embryos, newborn, and adult mice by immunohistochemistry and in situ hybridization. During rat amelogenesis, at the secretion phase, MMPs and RECK were immunostained in the ameloblast

10. Analysis of known gene for enamed development in families with amelogenesis imperfecta / Analise de gene relacionados a formação do esmalte dental em familias com amelogenese imperfeita
Amelogênese imperfeita (AI) representa um grupo de doenças hereditárias que causa defeito na formação do esmalte dental. Esse distúrbio afeta o esmalte em diferentes intensidades, promovendo desde a deficiência na formação do esmalte até defeitos no conteúdo mineral e protéico. O desenvolvimento do esmalte envolve a expressão de múltiplos genes

11. Mineralização do esmalte apos a remoção parcial dos ameloblastos pos-secretorios em incisivos inferiores de ratos / Enamel mineralization after partial removal of post-secretory ameloblasts in the rat lower incisors
The enamel organ of rat incisors at the maturation stage of amelogenesis (from the region were enamel rods are visible and the enamel is completely acid-soluble) was removed and the limits of the removal (surgical region) were marked by notches made at the labial face of the enamel. The enamel organ, from the incisal notch up to the alveolar crest, was damag

12. Efeitos da ingestão do alcool durante a gestação na imunoexpressão do EGF na amelogenese e dentinogenese do 1º molar inferior de ratos
Previous studies have reported that the maternal exposure to alcohol reduces the maxilo-fadal development, including a delay in the formation and eruption of the tooth, as well as, enamel anomalies. The mechanisms of these deleterious effects are not fully clarified. The objective of this study was to analyze using polyclonal antibody of the Epidermal Growth
