Comparative Clinical Study of Coronally Positioned Flap with and Without Dehydrated Amnion Allograft in the Treatment of Gingival Recession

A pleasing smile involves a harmonious relationship among the teeth, the gingival scaffold and the lip framework. In dental profession, aesthetics of the patient is the main factor to be focused on along with treating the disease of the patient. The primary goal of esthetic dental treatment is the restoration to a natural, healthy, and esthetic appearance from an otherwise damaged dentition [1]. Today, gingival reconstruction has become a routine part of periodontal practice. The ability to cover exposed and sensitive roots and crown margins, to reconstruct lost ridges, and to enhance prosthetic reconstruction has undergone a rapid explosion [2]. Numerous surgical methods and materials have been used for the treatment of gingival recession. Some of the materials used in these techniques are autogenous free gingival grafts, autogenous connective tissue grafts and allograft dermis tissue [3]. Besides, biologic mediators such as enamel matrix derivative, hyaluronic acid gel and recombinant platelet derived growth factorhave been imported into surgical protocols with the intent of advancing and influencing the wound healing [4-6]. Coronally advanced flap procedure is currently seen as one of the most predictable technique available to achieve root coverage, while maintaining high aesthetics [7]. Clinical results with coronally advanced flap procedure have been promising showing improved root coverage, gain in clinical attachment level (CAL) and increased width of keratinized gingiva [8]. It also helps in overcoming the several disadvantages of free gingival grafts and connective tissue grafts, like the need of second surgical site, which is an additional discomfort to the patients.
