Comparative clinical evaluation of laterally positioned pedicle graft and subepithelial connective tissue graft in the treatment of Miller's Class I and II gingival recession: A 6 months study.

AIM: The purpose of the study was to compare clinical outcomes of laterally positioned pedicle graft (LPPG) and subepithelial connective tissue graft (SCTG) for treatment of Miller's Class I and II gingival recession defects, at the end of 6 months.

MATERIALS AND

METHODS

Sixty Miller's Class I or II gingival recession defects (≥3 mm) (n = 30 each) on the labial aspect of anterior teeth were treated by either of the above techniques. Clinical parameters including recession depth (RD), width of keratinized gingiva (WKG), percentage of root coverage (%RC), and complete RC were recorded at baseline and 6 months postoperatively. Data were recorded and statistical analysis was done for both intergroup and intragroup.

STATISTICAL ANALYSIS USED: Paired t-test intragroup and Student's t-test intergroup.

RESULTS

In LPPG, RD decreased from 4.9 ± 0.99 mm to 1.1 ± 0.3 mm and WKG increased from 0.7 ± 0.87 to 4.5 ± 0.86 mm at 6 months, while in SCTG, RD decreased from 4.67 ± 1.12 mm to 0.46 ± 0.68 mm and WKG increased from 1.1 ± 0.99 to 5.33 ± 0.72 mm at 6 months postoperatively. The values of the soft tissue coverage remained stable for 6 months.

CONCLUSIONS

Highly significant and effective soft tissue coverage was obtained by both techniques. LPPG resulted in effective soft tissue coverage for isolated deep narrow defects while SCTG in isolated and multiple, deep narrow and wide defects.
