**7. Concluding remarks**

At present, the clinical application of the effect of genetics in periodontics is minimal. Despite several researches revealing association of candidate gene polymorphisms with periodontal disease, lacunae lies owing to co-existence of multiple etiotrophic factors and the plausible role of epigenetics in the periodontal disease severity. Future research shall be directed towards multiple genes, their interactions and role of epigenetics in modifying the periodontal etiopathogenesis.
