Tooth Agenesis and Associated Tooth Developmental Anomalies [PDF]

Česká stomatologie a praktické zubní lékařství, 2014
Aim of study: Tooth agenesis means absence or incomplete development of tooth. It is the most common developmental dental anomaly in man. The prevalence of agenesis in permanent dentition (excluding third molars) in common population oscillates between 2.6% and 11.3%. It is frequently associated with other dental developmental anomalies.

MSX1 variant causes nonsyndromic tooth agenesis in a Japanese patient [PDF]

Human Genome Variation
MSX1 variants are associated with autosomal dominant craniofacial developmental anomalies, including congenital tooth agenesis. Here, whole-exome sequencing in a Japanese patient with congenital tooth agenesis identified a novel de novo heterozygous ...

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 ...

Tooth Agenesis Patterns in Orofacial Clefting Using Tooth Agenesis Code: A Meta-Analysis. [PDF]

Dent J (Basel), 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 ...

Retrospective Evaluation of Tooth Agenesis in Different Regions of Turkey with Panoramic Radiography [PDF]

Acta Stomatologica Croatica
Objectives: Dental agenesis refers to the absence of one or more teeth, occurring in both primary and permanent dentitions. It can result in several complications, impacting functional aspects of the dentition, such as chewing and speech.

Novel MSX1 Gene Variants in Chinese Children with Non-Syndromic Tooth Agenesis: A Clinical and Genetic Analysis [PDF]

Children
Background: Tooth agenesis is the most frequently occurring genetic developmental anomaly in clinical dentistry. The MSX1 gene, essential for tooth development, has been associated with non-syndromic tooth agenesis. This study aims to identify novel MSX1

FGFR1 variants contributed to families with tooth agenesis [PDF]

Human Genomics, 2023
Background Tooth agenesis is a common dental anomaly that can substantially affect both the ability to chew and the esthetic appearance of patients. This study aims to identify possible genetic factors that underlie various forms of tooth agenesis and to
