Influence of Periodontal Phenotype on the Outcome of Non Surgical Periodontal Therapy

Abstract

Aim and Objectives: The present study was designed to examine and compare the influence of periodontal phenotype on the outcome of SRP done with manual and ultrasonic instruments.

Methodology: Forty patients with stage 1 and stage 2 periodontitis participated in this study. All patients underwent SRP either with hand or ultrasonic instruments. Study included 4 groups, viz., Patients with Thin Biotype undergoing SRP using hand instruments (TN-H) (n=10) and ultrasonic instruments (TN-U) (n=10) respectively. Patients with Thick Biotype who underwent SRP using hand instruments (TK-H) (n=10) and ultrasonic instruments (TK-U)(n=10) respectively. PPD and Gingival Shrinkage (GSH) of labial side of maxillary anterior teeth were evaluated at baseline and 3 months after SRP in all four groups. The results were statistically analysed using Analysis of variance followed by Pot-hoc analysis using Boferroni Test; and Paired-t-Test and Independent-t-Test.       

Results: With regard to PPD, no difference was between groups. However GSH were statistically significant in the thin biotype group who underwent NSPT using ultrasonic instrument.

Conclusion: Thin gingival phenotype is more prone to gingival shrinkage when ultrasonic instrumentation is performed in comparison with hand scaling. However there was no statistically significant change in PPD.
