Abstract

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.

Keywords: Gingiva recession, Root coverage, Langer and Langer technique, Bruno technique
