Evaluation of Root Coverage by Connective Graft and Different Root Conditioning Methods

Evaluation of Root Coverage by Subepithelial Connective Graft Associated to Root Conditioning by Citric Acid Plus Tetracycline and Antimicrobial Photodynamic Therapy: A Randomized Clinical Trial

The aim of this study was to evaluate the effect of two root-conditioning agents used in conjunction with subepithelial connective graft technique on root coverage outcomes. One is citric acid plus tetracycline and the other is antimicrobial photodynamic therapy.

Citric acid plus tetracycline has properties of root surface decontamination, surface demineralization and exposure of collagen fibers.

Antimicrobial photodynamic therapy has been widely used in Periodontics to obtain reduction of periodontopathogenic bacteria with absence of systemic side effects and minimal bacterial resistance. Also, it has properties of root demineralization and exposure of collagen fibers. These properties may enhance root coverage in procedures of subepithelial connective graft.

Inclusion Criteria:

• Indication of root coverage by dentin hypersensitivity or esthetic

Exclusion Criteria:

• Smokers
• Pregnancy
• Systemic medication use that could impair wound healing or surgery procedure
• Systemic diseases as diabetes, uncontrolled hypertension, coagulation diseases, kidney diseases.
