Introduction: Dentin dysplasia is a rare autosomal dominant inheriting disturbance of dentin formation characterized by normal enamel formation, but atypical dentin with abnormal pulpal morphology. There are two major patterns: type I and type II. Amelogenesis imperfecta is an autosomal dominant. X-link inherent disease that is classified by clinical manifestation into hypoplastic, hyp...

INTRODUCTION Osteogenesis imperfecta is a heritable disorder affecting bone and tooth development. Malocclusion is frequent in those affected by osteogenesis imperfecta, but this has not been studied in detail. The purpose of this study was to describe and quantify the severity of malocclusions in patients with osteogenesis imperfecta. METHODS Articulated dental casts were obtained from 49 pa...

The effects of dietary sucrose feeding, intragastric sucrose feeding and dietary calcium-deficiency on primary dentinogenesis of the pulp-dentin organ and caries progression were examined in an experimental rat model. The possible role of calcium balance and reduced mineralization of dentin organic matrix as a cause of reduced dentin formation in young, fast growing, rats were also studied. Dur...

Osteogenesis imperfecta is a genetic disorder of type I collagen. Although multiple genotypes and phenotypes are associated with osteogenesis imperfecta, approximately 90% of the mutations are in the COL1A1 and COL1A2 genes. Osteogenesis imperfecta is characterized by bone fragility. Patients typically have multiple fractures or limb deformity; however, the spine can also be affected. Spinal ma...

Amelogenesis imperfecta is a group of genetic disorders that affects both the morphology and quality of tooth structure. Although the disease entity is primarily associated with abnormalities of dental and oral structures, it has been reported to be associated with a few syndromes. A 9-year-old girl with minor thalassemia referred to the Department of Pediatric Dentistry of the Mashhad Faculty ...

Osteogenesis imperfecta is a disease characterized by increased fragility of the bones which are easily fractured by slight trauma. Patients suffering from this disorder usually have blue sclerae and flaccid ligaments; some of them become deaf later in life. Scattered reports of this disorder date back at least to 1678 (quoted by Seedorff in 1949). Vrolik (1849) described the disease in the new...

The dentin dysplasias (DD), which may be classified as type I (DD1) or type 2 (DD2), form a group of rare, inherited abnormalities that are clinically distinct from dentinogenesis imperfecta. Studies of affected families may help to distinguish different types of DD and provide further insight into their etiology and clinical management. This report describes a family that showed characteristic...

There are currently 67 dental schools in the United States and Puerto Rico. According to the 2014 edition of the Official Guide to Dental Schools For Students Entering in Fall 2015 published by the American Dental Education Association (www.adea.org), no dental schools currently require genetics prior to admission. Only one school, the University of Florida, requires one semester of molecular b...
