Comparative evaluation of envelope type of advanced flap with and without type I collagen membrane (NEOMEM™) in the treatment of multiple buccal gingival recession defects: A clinical study.

Gupta P, Gupta H - Indian J Dent (2014)

Bottom Line: Both the treatments resulted in significant recession depth reduction (P < 0.001), but the reduction was significantly greater (P < 0.01) for Group B than Group A.The probing depth changes were significant (P < 0.01) for both groups, but the difference was nonsignificant.The width of keratinized tissue was also significantly (P < 0.001) increased in both groups, but the increase was significantly greater (P < 0.001) in group B (2.30 ± 1.06 mm) than in group A (1.21 ± 0.67 mm).

ABSTRACT

Background: The aim of this study is to compare and evaluate the clinical outcome of the envelope-type of coronally advanced flap (CAF) alone versus envelope type of coronally advanced flap plus type I collagen membrane (NEOMEM) in the treatment of multiple buccal gingival recessions, using the split mouth study.

Materials and methods: Ten patients in the age group of 20-50 years showing bilateral gingival recessions were treated. The defects in each patient were randomly assigned as Group A, which were treated with the envelope type of CAF, and those in Group B were treated with envelope type of CAF along with the Type I collagen membrane (NEOMEM). The recession depth (RD), probing depth (PD), clinical attachment level (CAL), and width of the keratinized tissue (KT) were measured at baseline, at three and six month intervals.

Results: Forty-six Miller's class I and II gingival recessions were treated. In the CAF + Type I collagen membrane (NEOMEM)-treated (Group B) sites the baseline gingival recession was 2.34 ± 0.48 mm, while in the CAFtreated (Group A) sites it was 2.52 ± 0.84 mm. Both the treatments resulted in significant recession depth reduction (P < 0.001), but the reduction was significantly greater (P < 0.01) for Group B than Group A. The probing depth changes were significant (P < 0.01) for both groups, but the difference was nonsignificant. Similarly, a significant gain of CAL was seen in Group B (2.23 ± 0.75 mm, P < 0.001) as well as in group A (1.60 ± 0.86 mm, P < 0.001) showing a significant difference (P < 0.01) between the two groups. The width of keratinized tissue was also significantly (P < 0.001) increased in both groups, but the increase was significantly greater (P < 0.001) in group B (2.30 ± 1.06 mm) than in group A (1.21 ± 0.67 mm).

Conclusion: The envelope type of CAF along with Type I collagen membrane (NEOMEM) was more effective than envelope type of CAF alone, in producing root coverage in multiple gingival recession defects, associated with gain in CAL as also in the width of KT.
