Leong's Premolar

What is Leong’s premolar?

Some permanent premolars have a projected portion of the tooth structure which is fragile; this kind of premolar is called 'Leong's Premolar'. If the projected portion fractures, the pulp inside the tooth may be infected and becomes necrotic, or even results in formation of abscess.
