AI Article Synopsis

  • - Tooth agenesis (TA) is a condition where tooth development stops early on and can be classified into two types: non-syndromic (NSTA) and syndromic (STA), based on whether it affects other body systems.
  • - Genetic factors are mainly responsible for TA, with many genes, especially WNT10A and EDA, linked to this condition; mutations in these genes are common in cases of NSTA and certain syndromes.
  • - The review details what is currently known about the genetic basis of NSTA and STA, particularly looking at how mutations in WNT10A and EDA are connected to the number of teeth that are absent in affected individuals.

Article Abstract

Tooth agenesis (TA) occurs when tooth development is disrupted at the initiation stage. It can be classified into non-syndromic and syndromic forms (named NSTA and STA), depending on whether it is accompanied by abnormalities of other organs and systems. Genetic factors play a predominant role in the pathogenesis of tooth agenesis, with dozens of genes implicated in both forms. Several genes have been identified, mutations in which can lead to both forms of TA. Among these, WNT10A and EDA are frequently mutated genes in this context, representing extensively researched and documented genes in human non-syndromic selective agenesis of permanent teeth and their association with ectodermal dysplasia syndromes. In this review, we present an overview of the current knowledge regarding genes associated with NSTA and STA, focusing on the distribution and nature of WNT10A and EDA gene mutations. We also explore how these mutations relate to the condition's both forms, including their association with the number of missing permanent teeth.

Objective: To evaluate the frequency of tooth anomalies (TA) in the deciduous and permanent dentition of patients with nonsyndromic orofacial clefts (NSOC), both inside and outside the cleft area.

Methods: The following databases were searched for the relevant literature: Cochrane, OVID, SciELO, Embase, Livivo, PubMed, Scopus, and Web of Science. The risk of bias was analyzed using the Joanna Briggs Institute.

Background: Morphological and structural abnormalities are common dental anomalies. Identifying DA and determining their prevalence can play an important role in reducing the risk of surgical intervention and improving occlusion, leading to successful dental treatments. Thus, this study aimed to determine the prevalence of DA using panoramic radiographs (OPG) in Makkah, Saudi Arabia according to gender.

Prevalence and root canal morphology of taurodontism analyzed by cone-beam computed tomography in Northern China.

BMC Oral Health

January 2025

Department of Endodontics, Beijing Stomatological Hospital, Capital Medical University, Tian Tan Xi Li No.4, Beijing, 100050, China.

Background: To evaluate the prevalence and characteristics of taurodontism in northern China by using cone-beam computed tomography (CBCT) and assisting the treatment.

Methods: The study involved CBCT scans of 8112 teeth from 507 participants of northern China, comprising 217 males and 290 females aged 18 to 60. Analysis was conducted using Shifman and Chanannel's criteria to assess the prevalence and attributes of taurodontism, examining differences based on tooth position (maxilla and mandible) as well as gender (P < 0.

Background: Molariform second premolar is a rare dental anomaly where the second premolar resembles a molar in size and shape. This condition is often linked to macrodontia, a rare enlargement of teeth that disrupts dental proportions and can manifest in isolated, relative, or generalized forms. Although mandibular second premolars are more prone to morphological variability, the occurrence of bilateral molariform premolars, induced by a unique form of gemination, is exceptionally uncommon and infrequently documented, thus making this case clinically significant.

Agenesis of maxillary lateral incisors: Bone formation by orthodontic tooth movement and long-term stability of the edentulous alveolar ridge at 12-15 years after treatment.

Am J Orthod Dentofacial Orthop

Department of Orthodontics, Faculty of Medicine and Dentistry, Palacky University, Olomouc, Czech Republic; Department of Dentistry, First Faculty of Medicine, Charles University and the General University Hospital, Prague, Czech Republic. Electronic address:

Introduction: The primary aim of this study was to assess the amount and long-term stability of orthodontically created bone in patients with agenesis of maxillary lateral incisors after canine distalization. The secondary aim was to explore the impact of patient age on the process of alveolar bone resorption.

Methods: A group of patients with agenesis of the maxillary permanent lateral incisor was examined at 4 time points: the beginning of orthodontic treatment (T1, n = 80), the end of treatment (T2, n = 80), 2-5 years after treatment (T3, n = 79), and 12-15 years after treatment (T4, n = 32).
