Root Coverage Clinical Trial
Official title:
Root Coverage With Connective Tissue Graft Associated With VISTA Versus Tunnel Technique in Miller Class I & II Recession Defects A Randomized Controlled Clinical Trial
Several techniques were proposed in the literature to solve the problems associated with
gingival recession. Root coverage was mainly indicated for esthetic concern, however, it
might also be indicated for treatment of root hypersensitivity and maintaining adequate
plaque control by keratinized tissue augmentation.
These proposed surgical techniques were well-documented with successful outcomes. Each
technique had its own advantages, disadvantages and indications. Various factors affected the
most suitable technique. These factors were either related to the dimensions of gingival
recession defect, or related to the surgeon experience or to the patient himself .
Nowadays, the scope of scientific research is concerned with designing surgical techniques
that are more predictable, high esthetic, less invasive and patient centered In this way,
continuous modification of surgical techniques aroused to result in a more reproducible
outcomes; such as the attempt to advance pedicle flaps without vertical releasing incisions,
as in the modified coronally advanced flap and the modified microsurgical tunnel technique.
However, controversy still exist in the literature regarding the best technique for root
coverage. Coronally advanced flap is the most commonly reported technique in research, with
lack of researches on tunneling techniques.

Other | Post-Operative Pain | post operative pain will be measured using visual analogue scale (VAS). Visual analogue scales (VAS) are used to measure the intensity or frequency of the symptoms and the pain. They are generally completed by patients themselves. The used scale in this study is a horizontal straight line of a fixed length (100 mm) and numbered every 10 mm ranging from "0 - no pain" to "100 - intolerable pain" | immediately post operative | |
