Impact of Tooth Location on the Treatment of Multiple Gingival Recessions with Connective Tissue Graft Associated with A Coronally Advanced Flap

Abstract

Objectives: Coronally advance flap (CAF) effectiveness has been extensively evaluated, but little information is available regarding the effect of tooth position. This study aimed to evaluate the influence of tooth location on the outcomes of CAF with subepithelial connective tissue graft (SCTG) in the treatment of gingival recessions defects (GRs). Materials and Methods: Nineteen patients with a mean age of 36.3 ±7.6 years (11women, 8 men), each contributing Miller Class I and II GRs, were selected. Forty-four defects were treated with a combination of a CAF and a SCTG. Gingival recession depth (RD), gingival recession width (RW), probing depth (PD), and clinical attachment level (CAL) were recorded at baseline and 12 months postoperatively Results: The mean root coverage from baseline to 1year post-surgery was 89 % for the maxillary GRs and 68 % for the mandibular GRs. RD and RW were decreased in both groups from baseline to 12 months (p<0.001), but the difference between groups was not statistically significant. Both treatments showed satisfactory root coverage esthetic scores (maxillary teeth 8.2 ±1.3 and in mandibular teeth 7.6 ± 1.1). Conclusions: The findings of the current study have shown that the CAF is an effective procedure for the treatment of multible GRs. Besides, the two groups (maxillary and mandibular GRs) showed similar significant improvements from baseline to 12 months evaluations.
