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 ...

OBJECTIVE To investigate the prevalence of impaction of permanent mandibular second molars and associated dental and radiographic characteristics of Chinese children in Hong Kong. MATERIALS AND METHODS Dental and radiographic records of a group of Chinese schoolchildren were studied retrospectively. Cases of impaction of 1 or both permanent mandibular second molars were selected. Demographic ...

Objectives We reassess the taxonomic assignment and stratigraphic context of a permanent upper first molar lower third premolar recovered from archeological site Lezetxiki in North Iberian Peninsula. Materials Methods assessed external internal morphology teeth using qualitative descriptions, crown diameters, dental tissue proportions, geometric morphometrics. The were compared with Middle Plei...

Background: The prevalence of dental anomalies in children with cleft lip and palate (CLP) has been said to be higher than in the normal children; however, such findings have not been expressed for different racial groups. Aim: To determine the prevalence of anomalies in children with CLP and to ascertain if there were any differences between the prevalence figures for CLP and non-CLP children....

BACKGROUND The aim of this study was to describe the pattern of inheritance and the clinical features in a large family with Waardenburg syndrome type I (WS1), detailing the dental abnormalities and screening for PAX3 mutations. MATERIAL AND METHODS To characterize the pattern of inheritance and clinical features, 29 family members were evaluated by dermatologic, ophthalmologic, otorhinolaryn...

The Ellis-van Creveld (EVC) syndrome is a chondroectodermal dysplasia and is characterized by the cardinal features of disproportionate short stature, polydactyly, hidrotic ectodermal dysplasia, and congenital heart malformations, along with other skeletal and dental abnormalities. It is a rare condition, with very few cases reported in the medical literature. It is inherited as an autosomal re...

Osteogenesis imperfecta (OI) is a rare hereditary condition caused by changes in collagen metabolism. It is classified into four types according to clinical, genetic, and radiological criteria. Clinically, bone fragility, short stature, blue sclerae, and locomotion difficulties may be observed in this disease. OI is often associated to severe dental problems, such as dentinogenesis imperfecta (...

Background Variants in DLX3 cause tricho-dento-osseous syndrome (TDO; MIM accession no. 190320), a systemic condition with hair, nail, and bony changes, taurodontism, amelogenesis imperfecta (AI) inherited an autosomal dominant fashion. Different variants found within this gene are associated different phenotypic presentations. To date, 6 have been reported TDO. The aim of paper is to explore d...
