About

The primary course of periodontal treatment is non-surgical periodontal therapy followed by surgical therapy, if required, with an aim to arrest ongoing inflammatory periodontal destruction along with reconstruction of lost apparatus if possible. There is no protocol established for completing scaling and root planing (SRP) in patients with generalized advanced periodontitis. In some cases SRP is completed in single sitting whereas in other cases supragingival scaling is followed by subgingival SRP in the next appointment. It is hypothesized that presence of reparative components near the base of the pocket could result in better treatment outcomes after scaling and root planning done in single sitting when compared to supragingival scaling followed by sub-gingival scaling and root planning after one week.

Full description

The aim of this randomized controlled clinical trial is to clinically compare the outcomes of scaling and root planing (SRP) completed in single sitting vs supragingival scaling followed by subgingival scaling and root planing after one week in Stage II and Stage III generalised periodontitis patients.

OBJECTIVES:

1. To assess the improvement in clinical parameters viz. bleeding on pocket probing (BOPP), pocket probing depth (PPD), clinical attachment level (CAL), plaque index (PI), gingival index (GI), bleeding on marginal probing (BOMP), gingival marginal position (GMP) and gingival recession (GR) by single sitting scaling and root planning versus supragingival scaling followed by subgingival scaling and root planing after one week in Stage II and Stage III generalised periodontitis patients.
2. To assess the correlation between availability of Vascular Endothelial Growth Factor (VEGF) at the base of the pocket and treatment outcomes.

SETTING: Department of Periodontology and Oral Implantology, PGIDS, Rohtak, Haryana.

STUDY DESIGN: Split-mouth Randomized controlled clinical trial.

TIME FRAME: 12 months

POPULATION: Systemically healthy patients with Stage II and Stage III Generalised Periodontitis with more than 20 teeth present.

SAMPLE SIZE: To be able to detect a clinically meaningful difference of 1mm and 10% improvement in PPD and BOPP respectively between groups, assuming an effect size of 0.85 with a power of 80% and 5% level of significance, a minimum sample size of 22 patients are needed in each group. Accounting for a 20% drop out rate, 27 patients are needed in each group.

METHODOLOGY: Patients with stage II and III generalised periodontitis will be recruited from the outpatient Department of Periodontology, PGIDS, Rohtak. Patients fulfilling the eligibility criteria will be enrolled in the study after obtaining an informed written consent. A split-mouth design will be chosen using two contra-lateral quadrants per group being randomly assigned into test (single sitting SRP) and control (supragingival scaling followed by subgingival scaling after a week) group for each patient using a chit-method.

Enrollment: 27 estimated patients
