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.

Familial aggregation of maxillary lateral incisor agenesis [PDF]

, 2010
In spite of recent developments, data regarding the genes responsible for the less severe forms of hypodontia are still scarce and controversial. This study addressed the hypothesis that agenesis of maxillary lateral incisors (MLIA) is a distinct type of

Periodontal and orthodontic management of impacted canines

Periodontology 2000, EarlyView.
Abstract The maxillary and mandibular canines are described by many clinicians as the “cornerstone” of the arch. When in their optimal position, they play a critical role in providing a well‐balanced occlusal scheme that contributes toward functional as well as neuromuscular stability, harmony, esthetics, and dentofacial balance.

Local application of Usag-1 siRNA can promote tooth regeneration in Runx2-deficient mice

Scientific Reports, 2021
Runt-related transcription factor 2 (Runx2)-deficient mice can be used to model congenital tooth agenesis in humans. Conversely, uterine sensitization-associated gene-1 (Usag-1)-deficient mice exhibit supernumerary tooth formation.
