In oral cavity, there are many information like angulation, occlusion, configuration, and dental fillings make teeth unique to a person so that the individual can be identified based on the precision and clarity of his teeth. Saliva is one of body fluids in the oral cavity that contains DNA. Individualization of DNA profiles is quite high. The use of DNA analysis lately has been widespread in the scope of forensic dentistry. In the field of investigation of forensic odontology, DNA can be extracted from epithelial cells contained in saliva and/or teeth. The orofacial region is a good source for sampling for DNA analysis because the oral tissues are more resistant to environmental degradation and damage from temperature, electricity, or mechanics. This article will review about evidence that can be obtained in forensic cases where the evidence is related to the oral cavity and how to collect the sample. DNA can be extracted from epithelial cells contained in saliva and/or teeth. Saliva can affect objects that we often use, especially those related to the oral cavity and have proven to be a good source for DNA analysis in forensic cases.
