Dissecting the Genetic Contribution of Tooth Agenesis. [PDF]

Int J Mol Sci
Tooth agenesis (TA), the congenital absence of one or more teeth, is the most common manifestation of defective dental morphogenesis in humans. TA can occur as an isolated (non-syndromic) condition or as part of a broader syndromic presentation. In this review, we analyzed a total of 73 manuscripts to provide a comprehensive update on the genetic ...

Subphenotypes in Non-Syndromic Orofacial Cleft Patients Based on the Tooth Agenesis Code (TAC)

Children, 2022
Background: It was the aim of this study to investigate tooth agenesis patterns, which are expressed to different subphenotypes according to the TAC method in a spectrum of non-syndromic orofacial cleft patients.

Tooth Agenesis Patterns in Orofacial Clefting Using Tooth Agenesis Code: A Meta-Analysis

Dentistry Journal, 2022
Individuals with orofacial clefting (OFC) have a higher prevalence of tooth agenesis (TA) overall. Neither the precise etiology of TA, nor whether TA occurs in patterns that differ by gender or cleft type is yet known. This meta-analysis aims to identify the spectrum of tooth agenesis patterns in subjects with non-syndromic OFC and controls using the ...

Research progress on pathogenic genes and molecular mechanisms of nonsyndromic tooth agenesis

口腔疾病防治, 2020
Tooth agenesis is a common tooth number deficiency that occurs in the tooth-forming process or earlier period of tooth germ development and has a serious impact on the maxillofacial development, aesthetics and masticatory function of patients.

TOOTH AGENESIS - THE PROBLEM AND ITS SOLVING IN OUR PRACTICE, PREVALENCE AND RELATION WITH OTHER DEFORMITIES. [PDF]

Journal of IMAB, 2015
Tooth agenesis is an orthodontic abnormality affecting the number of teeth. This leads to various types of malocclusion, disturbance in the masticatory function and poor esthetics. This survey includes 1510 orthodontic patients treated by us.

Novel WNT10A variant in a Japanese case of nonsyndromic oligodontia

Human Genome Variation, 2023
Congenital tooth agenesis is one of the most common anomalies in humans. Many genetic factors are involved in tooth development, including MSX1, PAX9, WNT10A, and LRP6. Thus, mutations in these genes can cause congenital tooth agenesis in humans. In this

Effect of Tooth Agenesis on Mandibular Morphology and Position [PDF]

International Journal of Environmental Research and Public Health, 2021
Congenital missing teeth (OMIM #106600) is the most common dental abnormality. The aim of the study was to evaluate the effects of tooth agenesis on the total mandibular length, length of the mandibular body and alveolar process, and the mandibular anteroposterior position.

Estimation of dental age in children in a Turkish population with tooth agenesis

, 2023
Aim: The aim of this study was to investigate tooth development according to chronological age in children with tooth agenesis and to determine whether the severity of tooth agenesis (hypodontia and oligodontia) has an effect on tooth development ...

Genetic Variants in miRNAs Are Associated With Risk of Non-syndromic Tooth Agenesis

Frontiers in Physiology, 2020
Non-syndromic tooth agenesis (NSTA) is one of the most common dental abnormalities. MiRNAs participated in the craniofacial and tooth development. Therefore, single nucleotide polymorphisms (SNPs) in miRNA genes may contribute to the susceptibility of ...
