Clinicians often encounter the need for crown lengthening in the practice of dentistry and have to make treatment decisions taking into consideration how to best address the biological, functional, and esthetic requirements of each particular case. The concept of crown lengthening was first introduced by D.W. Cohen (1962) and is presently a procedure that often employs some combination of tissue reduction or removal , osseous surgery , and/or orthodontics for tooth exposure and increasing the extent of supra gingival tooth structure for restoration of aesthetic purposes . Gingivectomy and gingivoplasty considered kind of crown lengthening procedure. Gingivectomy is defined as the excision of the soft tissue wall of a pocket. The procedure is usually combined with the recontouring of hyperplastic tissue by gingivectoplasty to restore physiological gingival form . Gingivoplasty is a reshaping of the gingiva to create physiologic gingival contours, with the sole purpose of recontouring the gingiva in the absence of pockets. In doing so, the complete anatomical crown becomes exposed and pseudo pockets are eliminated creating a better environment for periodontal health. Treatment options for crown lengthening procedures include: Surgical, Electrocautery or by Laser. The aim of the present study was to compare the practical effectiveness and postoperative parameters of using diode laser and electrocautery for crown lengthening procedure.
