Developmental disturbances involving the oral cavity affect the growth and development of a child. Tooth agenesis may be associated with a number of documented syndromes or may present as an isolated entity. The presence or absence of teeth is decided by the influence of various genes and their signaling pathways.

Tooth agenesis in down syndrome
American Journal of Medical Genetics, 1995AbstractWe studied the frequency and pattern of tooth agenesis in a Danish population with Down syndrome, trisomy 21 (46 females and 54 males). The control group consisted of a normal Danish population (2424 females and 2431 males) [Rølling, 1980: Scand J Dent Res 88:365–369; Ravn and Nielsen, 1973: Tandlaægebladet 77:12–22].

Tooth agenesis in a Portuguese population
International Orthodontics, 2012The aim of this retrospective study was to evaluate the prevalence and pattern of hypodontia in the permanent dentition, including and excluding third molars, in a Portuguese sample.The study group comprised 2888 patients, observed between 2005 and 2009 at the Dentistry Clinic of the Instituto Superior de Ciências de Saúde-Norte (ISCSN, Portugal).

The role of MSX1 in tooth agenesis in Iranians
International Journal of Paediatric Dentistry, 2007Introduction. MSX1 gene has a critical role in craniofacial development, the aim of this case–control study is to test the hypothesis that MSX1 mutation contributes to congenital tooth agenesis in Iranians.Materials and methods. The study group consisted of 20 affected individuals with tooth agenesis of lower second premolars or upper lateral ...

Genetic basis of tooth agenesis
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, 2009AbstractTooth agenesis or hypodontia, failure to develop all normally developing teeth, is one of the most common developmental anomalies in man. Common forms, including third molar agenesis and hypodontia of one or more of the incisors and premolars, constitute the great majority of cases.

Rethinking the Genetic Etiology of Nonsyndromic Tooth Agenesis
Current Osteoporosis Reports, 2022Genetic studies in humans and animal models have improved our understanding of the role of numerous genes in the etiology of nonsyndromic tooth agenesis (TA). The purpose of this review is to discuss recently identified genes potentially contributing to TA.Despite research progress, understanding the genetic factors underlying nonsyndromic TA has been ...

[Correlation between the phenotype and genotype of tooth agenesis patients by tooth agenesis code].
Zhongguo yi xue ke xue yuan xue bao. Acta Academiae Medicinae Sinicae, 2013To analyze the correlation between the phenotype and genotype of tooth agenesis using the tooth agenesis code (TAC) and the traditional descriptor for missing teeth.Patients with isolated hypodontia caused by PAX9 or MSX1 mutation reported before May 2007 were enrolled. The teeth missing rate and TAC code were recorded.

Tooth agenesis and craniofacial morphology in an orthodontic population
American Journal of Orthodontics and Dentofacial Orthopedics, 2002Previous reports have produced conflicting conclusions regarding the relationship among tooth agenesis, the congenital absence of teeth, and variations in craniofacial morphology. Traditional cephalometric assessment and computer-assisted morphometric analysis of jaw size were used to reexamine this relationship in a white orthodontic population.

[Research advances in tooth agenesis].
Beijing da xue xue bao. Yi xue ban = Journal of Peking University. Health sciences, 2008Tooth agenesis constitutes one of the most common developmental anomalies in man. Oligodontia is defined as congenital absence of six or more teeth. Based on the studies of our team in cooperation with Peking University Center for Human Disease Genomics in the past five years, this article reviews the current research progress in clinical phenotypes ...
