RESUMO
PURPOSE: The purpose of this study was to compare clinical effect of the Langer & Langer technique , the modified Langer & Langer technique and Bruno technique. MATERIAL AND METHODS: 30 patients who have gingiva recession(Miller class I or class II) were carried root coverage. Langer & Langer technique(14 patients/32 tooth), modified Langer & Langer technique(5 patients/10 tooth) and Bruno technique(11 patients/18 tooth) was carried. At baseline and average 3 months after operation, it was estimated clinical index(Pocket depth, gingiva recession, clinical attachment level, keratinized gingiva, scar tissue, root coverage rate) by Williams style probe. RESULT: Root coverage rate is indicated Langer & Langer technique(85%), Modified Langer & Langer technique(86%) and Bruno technique(90%). CONCLUSION: All three of the procedures were effective in gingival recession and improved clinical parameters.
