| Abstract: |
Oral lesions caused by habits can be of teeth only, of teeth and the soft tissues of the mouth or may be only of the soft tissues. Lesions of teeth are permanent and may remain even when there has been total destruction of soft tissues. Recognition of lesions due to habits such as betel chewing, snuff dipping, pipe sming and certain sexual practices may help towards establishing the sex, the ethnic grouping or even the place of origin of a person or their remains. Certain dental and gingival changes may indicate a person's working circumstances and even the type of treatment received. PMID- 5345
