A COMPARATIVE EVALUATION OF THE EFFICACY OF PORCINE COLLAGEN MATRIX AND CHORION MEMBRANE USING CORONALLY ADVANCED FLAP TECHNIQUE FOR ROOT COVERAGE IN MULTIPLE ADJACENT MILLER’S CLASS I AND CLASS II GINGIVAL RECESSION- A 24 WEEKS CLINICAL STUDY

Gingival recession (GR) is the term that designates the oral exposure of the root surface due a displacement of the gingival margin apical to the cemento-enamel junction (CEJ). It is the most common and undesirable condition of the gingiva and its prevalence commonly increases with age. GR either localized or generalized, is one of the clinical features of periodontal disease and is frequently associated with clinical problems such as root surface hypersensitivity, root caries, cervical root abrasion, erosion, plaque retention and aesthetic dissatisfaction. The etiology is multifactorial and includes excessive or inadequate tooth brushing, destructive periodontal disease, tooth malposition, alveolar bone dehiscence, aberrent frenal pull, occlusal trauma, iatrogenic factors.

Various root coverage procedures are pedicle grafts, free gingival grafts, connective tissue grafts and membrane barrier guided tissue regeneration technique. In this study we will be comparing chorion membrane with Porcine collagen matrix with coronally advanced technique.
