Although a reasonably common dental condition, it can still be necessary to fix the gaps left by hypodontia. A. C. Lidral and B. C. Reising, The role of MSX1 in human tooth agenesis, Journal of Dental Research, vol. Among these genes, PAX9 (paired box gene 9), MSX1 (muscle segment homeobox 1), AXIN2 (axis inhibition protein 2), and EDA (ectodysplasin A) are the most frequently reported genes associated with nonsyndromic hypodontia [6, 5760]. Although numerous studies in the literature report on the prevalence, aetiology, and treatment of hypodontia, only few have investigated OHRQoL in individuals with hypodontia [73]. Notably, more adults are seeking orthodontic treatment. Hence, the identification of genetic and environmental factors may be particularly useful in the early prediction of this condition and the development of prevention strategies and novel treatments in the future. Hypodontia, also known as tooth agenesis, refers to a congenital condition where an individual is missing teeth. This will be followed by an outline of the theories surrounding hypodontia and a more detailed discussion of the specific factors, both genetic and environmental, that have been connected with this condition.

These terms include congenitally missing teeth, tooth agenesis, hypodontia, oligodontia, and anodontia. The term congenitally missing teeth is challenging because tooth development is completed after birth, so that the presence of most tooth germs can be proved only during childhood [46]. 8600 Rockville Pike Transposition of teeth is also seen more commonly in individuals with hypodontia [30]. It was also suggested that extractions did not impact the overjet, overbite, or incisor inclination [80].
