Analysis of Occlusal Traits Through the Analysis of Twins and Inbred Population

The most of dental and occlusal traits are polygeneticly and multifactorially determined and hereditary analysis can provide valuable information regarding the etiology of malocclusions. Twins analysis is frequently used tool to obtain genetic influence into developing dental and facial characteristics as well as to evaluate interactions between "nature" and "nurture". In population that is characterized with high rate of inbreeding, if some of recessive genes are mutated and/or responsible for some disturbances in occlusal relationships, prevalence of such deteriorated traits is expected to be higher in inbred than in general population. Occlusal traits were recorded in the sample of monozygotic twins, siblings, inbred population and the panmictic reference population. All children were in the age of mixed or early permanent dentition. In monozygotic twins mirror imaging of occlusal traits was observed. Our findings suggest important genetic role onto development of occlusal traits, especially on arch width and length.
