This study aimed to determine the criteria for quantifying developmental defects of enamel in primary teeth premature babies and investigate severity according gestational age, birth weight, systemic complications, treatments received after preterm birth. Birth information, a history duration parenteral nutrition, endotracheal intubation were investigated by retrospectively reviewing admission ...

Introduction:Uranium in drinking water and food is known to cause many medical problems. Several studies have been conducted to enquire about the health of people around limestone, coal etc mining areas. But little has been known about the people around uranium mines. Hence this study was done to evaluate the enamel defects present among the children residing near uranium mines in the Gogi Vill...

The aim of this study was to investigate the prevalence and psychosocial impact of enamel defects among 16-year-old school children on the island of Penang. The data were collected through a self-administered questionnaire survey and an oral examination, using the Modified Developmental Defects of Enamel Index (FDI, 1992). In all, 1024 subjects were selected using a multistage random sampling t...

Defective enamel formation is the defects occurring at the stages of enamel formation. Amelogenesis imperfect (AI) is a hereditary disorder that causes developmental disturbances in the structure of enamel. Quantitative defects in matrix formation leads to hypoplastic form of Amelogenesis imperfecta. Inadequate mineralization of matrix leads to hypocalcification and hypomaturationvariants. It i...

Developmental defects of enamel (DDE) are frequently observed. In both pediatric and orthodontic dental practices. DDE consist mainly of hypoplasia, diffuse and demarcated opacities.1 Often, a combination of enamel defects may be recognized in the same child (Fig. 1). Weerheijm et al. defined the term Molar Incisor Hypomineralization (MIH) to describe a more specific pattern of DDE: hypomineral...

Enamel hypoplasia is a defect in the enamel due to disturbance of ameloblastic function during amelogenesis. The etiology of such a disturbance may be either genetic or environmental in nature. This case report of undetected congenital idiopathic hypoparathyroidism emphasizes the importance of investigating the underlying cause of these enamel defects.

Abnormalities of enamel matrix proteins deposition, mineralization, or degradation during tooth development are responsible for a spectrum of either genetic diseases termed Amelogenesis imperfecta or acquired enamel defects. To assess if environmental/nutritional factors can exacerbate enamel defects, we investigated the role of the active form of vitamin A, retinoic acid (RA). Robust expressio...

This study of prematurely born children shows that the prevalence of enamel defects increases with decreasing birth weight. In very low birth-weight (VLBW, < 1500 g) children, the prevalence was 62.3 % compared to 27.3 % in the low birthweight (LBW, 1500-2500 g) group. In children with normal birth weight of > 2500 g, the prevalence was 12.8%. Both systemic and local factors contribute to the e...

This longitudinal study investigated the sequelae of enamel defects in a group of 25 white, very-low birthweight (VLBW), preterm children (mean birthweight 969 +/- 218 g, mean gestational age 27 +/- 1.9 weeks). Twenty-five race-, age-, and sex-matched, full-term normal birthweight (NBW) control children born at the same hospital, were selected randomly from hospital records. The children were e...
