The idea of such crime is to destroy any physical evidence of cause of death, time interval of death to body identification, and victim identification. Teeth are also good reservoirs for the identification of individuals by morphological as well as identification by mitochondrial DNA extraction. Aims and Objectives: To assess the morphological changes and duration of dissolution of teeth from different acids. Materials and Methods: Concentrated hydrochloric acid (HCl), nitric acid (HNO3), and sulfuric acid were employed for tooth. Results: Results showed that compared to sulfuric acid, HCl and HNO3 have more destructive capacity. Conclusion: Sulfuric acid, HNO3, and HCl criminals may be used to destroy the person identification; still, the individuals can be identified using teeth because it is the strongest structure of the human body and can preserve some structures even after exposure to the concentrated acids.
