Dental Restoration Guide

Leong’s premolar (www.toothclub.gov.hk)

Dens evaginatus is the dental term for the condition where the surface of the teeth has a protruding bump or cusp. It is said that this is more common in Asians and occurs more frequently on premolars than on any other types of teeth. On premolars, it is also known as Leong’s premolar. In some cases, it also happens to anterior teeth and is known as a talon cusp or eagle’s talon. The outcropping can break and might lead to infection and abscess. To prevent this, two things may be done: either the cusp can is reinforced with composite or removed and then restored using composite.
