AI Article Synopsis
- Non-syndromic tooth agenesis (NSTA) is a common dental issue linked to genetic factors, particularly miRNA single nucleotide polymorphisms (SNPs).
- A study involving 625 NSTA cases and 1,144 healthy controls identified the SNP rs2043556 as having significant associations with various types of tooth agenesis, particularly upper canines.
- The findings suggest that rs2043556 influences miRNA function, contributing to the risk of developing non-syndromic tooth agenesis.
Article Abstract
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 non-syndromic tooth agenesis. Here, a total of 625 non-syndromic tooth agenesis cases and 1,144 healthy controls were recruited, and four miRNA SNPs (/rs2910164, /rs11614913, /rs2043556, /rs2682818) were genotyped by the TaqMan platform. Rs2043556 showed nominal associations with risk of non-syndromic tooth agenesis ( = 0.021) in the overall analysis, as well as upper lateral incisor agenesis ( = 0.047) and lower incisor agenesis ( = 0.049) in the subgroup analysis. Notably, its significant association with upper canine agenesis was observed ( = 0.0016). Rs2043556 affected the mature of and while dual-luciferase report analysis indicated that was the binding target of Our study indicated that rs2043556 was associated with risk of non-syndromic tooth agenesis.

A new clinical index scale for measuring secondary alveolar bone grafting success based on canine eruption.
Eur J Orthod
December 2024
The Cleft Surgical Service for Scotland, Royal Hospital for Children, 1345 Govan Road, Glasgow, G51 4TF, United Kingdom.
Objectives: To develop a reproducible, reliable clinical index of alveolar bone grafting (ABG) outcome based on the eruption position of the cleft canine tooth and determine the association between eruption position and radiographic outcome at 6 months post-grafting.
Methods: Children with complete, non-syndromic, unilateral/bilateral cleft lip and palate in the West of Scotland were identified. Post-ABG radiographic outcome (Kindelan index) and canine eruption position in children with a cleft of the alveolus who had undergone ABG were documented.

Article Synopsis
- Tooth agenesis is the congenital absence of one or more teeth due to failures during the normal dental development process, with unclear causes, particularly in non-syndromic cases.
- The study reviewed 53 articles linking specific genes, such as PAX9 and WNT10A, to non-syndromic tooth agenesis, highlighting their roles in tooth formation and signaling pathways.
- Understanding the genetics and molecular mechanisms behind tooth agenesis is crucial for improving diagnosis and developing personalized treatment options, emphasizing the need for ongoing research in this area.
Article Synopsis
- The Roma population, numbering between 10 to 14 million worldwide, faces unique genetic challenges due to a high level of consanguinity, resulting in specific hereditary diseases that are often underdiagnosed.
- Recent clinical evaluations at the ERN CRANIO center in Prague have highlighted various rare genetic disorders, including congenital cataract syndrome and non-syndromic deafness linked to specific genetic mutations.
- This study emphasizes the need for awareness and accurate diagnosis of dental issues that can aid in better treatment and management of these genetic conditions in the Czech Roma community.

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.
