Introduction/Context

With aging, the physiologic function causes wear of teeth. Though, sometimes undue conditions prevail in the mouth causing them to wear faster. These conditions could be caused due to erosion due to acidic environment in the mouth, or parafunctional activity. Based on the pattern of the wear, they are of the following basic types: abrasion, abraction and attrition. Abrasion is usually seen in the cervical region of the teeth. Vigorous tooth brushing with high pressure is thought to be the cause of this. Abfraction is also caused in the facial cervical region due to flexural stresses caused by parafunction. It could be a c-shaped or a v-shaped defect based on the functional or non-functional cusps. Attrition is the most prevalent wear on the occlusal and incisal surfaces. It is physiological or could be accentuated by parafunction or erosive oral environment. All these conditions can be complicated by plaque accumulation and decay. Sometimes, presence of defected enamel or dentin can also affect the rate of wear and erosion, like, amelogenesis imperfecta, dentinogenesis imperfecta; and similar genetic syndromes.
