ABSTRACT
Epidemiological studies involving twins are unique in nature as it aids the researcher to investigate the effects of genes and environmental influences for a particular trait. Twin researches are valuable tools as it enlightens the knowledge on the various aspects of the human genome through molecular research methods. The combination of environmental factors and genetics for the development of a particular trait or phenotypes in humans are best demonstrated through the studies involving monozygotic (Identical) as well as dizygotic (Non-identical) twins. An investigation with twins enables to elaborate the genetic effects on the traits or conditions that are multifactorial in nature. Dental characteristics or conditions have multi-factorial inheritance and there is significant evidence in the literature of the influence of genes on the expression of dental and occlusal variables or characteristics which are irrefutable. This case report illustrates about 12-year-old non-identical twin sisters from the unique village of twins who exhibits a near identical dentition status and occlusal characteristics.
