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

open access: yesJournal 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.

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

open access: yes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.

Novel WNT10A variant in a Japanese case of nonsyndromic oligodontia

open access: yesHuman 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]

open access: yesInternational 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.

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

open access: yesFrontiers 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 ...

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

open access: yes, 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 ...

Involvement of and interaction between WNT10A and EDA mutations in tooth agenesis cases in the Chinese population. [PDF]

open access: yesPLoS ONE, 2013
BACKGROUND: Dental agenesis is the most common, often heritable, developmental anomaly in humans. Although WNT10A gene mutations are known to cause rare syndromes associated with tooth agenesis, including onycho-odontodermal dysplasia (OODD), Schöpf ...
