Sulcular Incision
A surgical cut made within the gingival sulcus along the tooth surface, used to initiate flap elevation while preserving the external gingival architecture.
Full Definition
A sulcular incision, also called a crevicular incision, is the primary incision in most periodontal flap procedures. The blade is inserted into the gingival sulcus and directed apically along the root surface to sever the junctional epithelium and the supracrestal fibres. Because the incision runs within the existing sulcus rather than through the external surface of the gingiva, the coronal gingival margin is preserved and post-operative aesthetics are generally favourable. This contrasts with an internal bevel incision, which removes the pocket lining by cutting from an external starting point. Editors of surgical technique manuscripts should verify consistent use of 'sulcular,' 'crevicular,' and 'intrasulcular' as the author's preferred synonym.
Usage
Usage note: The three synonyms — sulcular, crevicular, and intrasulcular incision — are used interchangeably by different authors. Flag inconsistency within a manuscript and standardise to one term.
