Aim: The aim of this randomized, controlled, clinical study was to compare two
surgical techniques with the acellular dermal matrix graft (ADMG) to evaluate which
technique could provide better root coverage.
Material and Methods: Fifteen patients with bilateral Miller Class I gingival recession
areas were selected. In each patient, one recession area was randomly assigned to the
control group, while the contra-lateral recession area was assigned to the test group. The
ADMG was used in both groups. The control group was treated with a broader flap and
vertical-releasing incisions, and the test group was treated with the proposed surgical
technique, without releasing incisions. The clinical parameters evaluated before the
surgeries and after 12 months were: gingival recession height, probing depth, relative
clinical attachment level and the width and thickness of keratinized tissue.
Results: There were no statistically significant differences between the groups for all
parameters at baseline. After 12 months, there was a statistically significant reduction
in recession height in both groups, and there was no statistically significant difference
between the techniques with regard to root coverage.
Conclusions: Both surgical techniques provided significant reduction in gingival
recession height after 12 months, and similar results in relation to root coverage.
