Overview
The present study will be performed on fourty-five patients suffering from periodontitis according to the criteria of American academy of periodontology to evaluate clinically effect of topical application of insulin versus hyaluronic acid as an adjunct to non surgical periodontal therapy in stage Ⅲ periodontitis patients.
This will be done by:
- Clinical assessment.
- Biochemical analysis. - Dose the topical application of insulin or hyaluronic acid as an adjunct to non-surgical periodontal therapy improves periodontal condition in stage Ⅲ periodontitis patients? PICO P (Population): patients with stage Ⅲ periodontitis. I (Intervention): non surgical periodontal therapy (SRP) with topical application using insulin or hyaluronic acid in periodontal pockets.
C (Comparison): topical application of insulin versus hyaluronic acid and SRP alone in periodontal pocket.
O (Outcome): primary outcome: change in periodontal pocket depth (PPD) or clinical attachment loss (CAL). Secondary outcome: change in gingival index (GI) or bleeding on probing index (BOP) and levels of IL-1β in GCF of treated pocket.
Study type: Randomized controlled trials (RCTs).
Description
The design of this clinical trial will be randomized double blind technique; the randomization of the patients will be performed through a computer program.
The randomization of patients will form the following 3 groups:
Group (Ⅰ): control group including (15) stage Ⅲ periodontitis patients who will receive scaling and root planning (SRP) alone.
Group (Ⅱ): including (15) stage Ⅲ periodontitis patients who will receive topical application of insulin adjunct to SRP.
Group (Ⅲ): including (15) stage Ⅲ periodontitis patients who will receive topical application of hyaluronic acid adjunct to SRP.
