متن کاملPrevalence and patterns of tooth agenesis among Malay children.
Tooth agenesis in Malay children, hitherto unreported, was assessed retrospectively from orthopantomograms of 834 healthy children aged 12-16 years who attended the Dental Clinic of Universiti Sains Malaysia. All teeth, including third molars, were assessed for agenesis. On an average, 2.3 teeth were missing per child. Missing third molars were found in 25.7% of children with one or two third m...
متن کاملTooth Agenesis
Tooth agenesis denotes a condition where teeth are missing due to a developmental failure. According to severity, this malformation can be subdivided into hypodontia, oligodontia and anodontia. With a frequency of 20–30%, tooth agenesis is the most prevalent dental dysplasia, but not all teeth are equally affected. Familial occurrence and concordance in twins indicate potential genetic causes. ...
متن کاملRadiographic Evaluation of Dental Development in Patients With Tooth Agenesis
Introduction: Hypodontia is one of the most common developmental anomalies. This study aimed to evaluate the variations of radiographic dental development in a group of Iranian children with dental agenesis. Materials and Methods: This study evaluated 1230 Orthopantomographs (OPGs) for agenesis of permanent teeth obtained from the patients aged between 8 and 18 years. Then the difference betwe...
متن کاملGenetic basis of dental agenesis - molecular genetics patterning clinical dentistry
Tooth agenesis is one of the most common congenital malformations in humans. Hypodontia can either occur as an isolated condition (non-syndromic hypodontia) or can be associated with a syndrome (syndromic hypodontia), highlighting the heterogeneity of the condition. Though much progress has been made to identify the developmental basis of tooth formation, knowledge of the etiological basis of i...
