Incisal

Full Definition

The term 'incisal' is specific to anterior teeth—incisors and canines—and describes the biting/cutting edge of these teeth, which is the equivalent surface to the 'occlusal' surface of posterior teeth. It appears in clinical charting, cosmetic dentistry reports, and orthodontic assessments when describing wear, fractures, or restorations at the tooth edge. Editors should flag incorrect use of 'occlusal' where 'incisal' is anatomically appropriate.

Usage

Usage note: 'Incisal' applies only to the cutting edges of incisors and canines. Using 'incisal' for premolars or molars is an anatomical error; the correct term for those teeth is 'occlusal'.
