Exonic and Intronic WNT10A Variants Isolated from Korean Children with Non-Syndromic Tooth Agenesis [PDF]

Diagnostics
Background/Objectives: Tooth agenesis (TA) is a developmental anomaly prevalent in humans. It is particularly significant in children and adolescents because it is related to esthetic, physiological, and functional problems, including malocclusion ...

Tooth Agenesis in Human Population: Treatment Considerations in Subjects with Tooth Agenesis

Pakistan Journal of Medical Research, 2023
Background: Tooth agenesis presents itself with one or more lost teeth and is one of the foremost common formative irregularities of the human dentition. Being polygenetic, it can occur entirely isolated or in conjunction with other syndromes. Methodology:Research papers published in English from 1950-2020 were searched. Studies on non-human subjects &

Genetic Basis of Nonsyndromic and Syndromic Tooth Agenesis [PDF]

Journal of Pediatric Genetics, 2016
Human dentition development is a long and complex process which involves a series of reciprocal and sequential interactions between the embryonic stomodeal epithelium and the underlying neural crest-derived mesenchyme. Despite environment disturbances, tooth development is predominantly genetically controlled.

Main genetic entities associated with tooth agenesis

Clinical Oral Investigations
Tooth agenesis refers to the absence of one or more of the deciduous or permanent teeth. Tooth agenesis results from a series of disrupted reciprocal ectodermal mesenchymal interactions taking place during the early stages of tooth development.A narrative literature review was performed to describe the main genetic syndromes associated with tooth ...

Patterns of tooth agenesis in individuals with Down syndrome

Special Care in Dentistry
AbstractAimsTooth agenesis (TA) is common in Down syndrome (DS). It is unknown whether this agenesis occurs in specific patterns, which is important regarding treatment planning and aetiological research. This study aimed to aggregate and analyze patterns of TA, excluding third molars, in individuals with DS using the tooth agenesis code (TAC).Methods ...

Small RNAs and tooth development: The role of microRNAs in tooth agenesis and impaction. [PDF]

J Dent Sci
Tooth development, or odontogenesis, is a complex process in which several molecular pathways play a key role. Recently, microRNAs, a class of approximately 20-nucleotide small RNA molecules that regulate gene expression, have been implicated in the odontogenesis process.

The Effects of Different Patterns of Tooth Agenesis on Tooth Dimensions [PDF]

Journal of Dentistry Indonesia, 2018
Objective: Tooth agenesis is a multifactorial condition accompanied by morphological differences. This study aimed to investigate the effects of different patterns of tooth agenesis on tooth dimensions. Methods: Records of children registered at the Department of Pedodontics and had tooth agenesis were reviewed, and those aged between 7 and 18 years of

Is Lateral Incisor Agenesis Associated with an Increased Occurrence of Tooth Agenesis Outside of the Cleft Region in Complete Bilateral Cleft Lip and Palate Patients? [PDF]

Iranian Journal of Orthodontics, 2022
Aim: This study compared the prevalence of tooth agenesis out of the cleft area in patients with complete bilateral cleft lip and palate (BCLP) with and without agenesis of maxillary permanent lateral incisors.Methods: Tooth agenesis was evaluated in ...

Exploring the Association Between Genetic Polymorphisms in Genes Involved in Craniofacial Development and Isolated Tooth Agenesis

Frontiers in Physiology, 2021
Tooth agenesis is a common congenital anomaly in humans and is more common in oral cleft patients than in the general population. Many previous studies suggested that oral cleft and tooth agenesis share a similar genetic background. Therefore, this study
