Extensive Tooth Wear A Case Report
Non carious loss of dental hard tissue, generically termed as tooth wear, is caused by combine processes of erosion, abrasion and attrition. Clinically, dental erosion is used to describe the physical results of a pathologic, chronic, localised, painless loss of dental hard tissue chemically etched away from the tooth surface by acid, without bacterial involvement5,13,19. On the other hand, abrasion is used to describe the pathological wearing away of dental hard tissue through abnormal mechanical processes involving foreign objects or substances repeatedly introduced in the mouth and contacting the teeth, while attrition represents physiological wearing away of hard tissue as a result of tooth to tooth contact with no foreign substance intervening 5,8. This report presents a 25 year old female patient with clinical manifestations of a severe tooth wear caused by several reasons.
