Clinical Evaluation of Nano-Hydroxyapatite as an Adjunctive to Minimally Invasive Non-Surgical Technique in the Treatment of Deep Intra-bony Defects

Sponsor: Cairo University

View on ClinicalTrials.gov

Summary

This randomized controlled clinical trial aims to evaluate the effectiveness of using nano-hydroxyapatite (nHA) gel alongside a minimally invasive non-surgical technique (MINST) to treat deep intra-bony defects in patients with Stage III periodontitis. While MINST is an effective method for cleaning deep periodontal pockets without the need for traditional surgery, the addition of nHA may further enhance soft tissue healing, improve cellular interaction, and promote bone regeneration. Participants in the study will be randomly assigned to one of two groups. The test group will receive the MINST procedure combined with the application of nHA gel directly into the periodontal pocket, while the control group will receive the MINST procedure alone. The primary goal of the study is to measure the decrease in probing pocket depth over a 6-month follow-up period to determine if the adjunctive use of nHA provides superior clinical outcomes compared to non-surgical treatment alone.

Interventions

PROCEDURE

Minimally invasive non-surgical technique (MINST)

Subgingival debridement using thin ultrasonic tips and Gracey mini-curettes under magnification, deliberately avoiding subgingival rinsing to support blood clot stabilization

BIOLOGICAL

nano-hydroxyapatite

A single dose of nano-hydroxyapatite (nHA) gel applied subgingivally directly into the periodontal pocket associated with the intrabony defect immediately following debridement
