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

Clinical Evaluation of Nano-Hydroxyapatite as an Adjunctive to Minimally Invasive Non-Surgical Technique in the Treatment of Deep Intra-bony Defects: A Randomized Controlled Clinical Trial
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.

- History of malignancy or chemotherapy/radiation in the past year.
- Use of bisphosphonates, corticosteroids, immunosuppressive antibiotics or anti-inflammatory agents within 6 months before periodontal therapy.
- Smokers (≥ 10 cigarettes per day).
- Pregnant or breastfeeding women, confirmed via medical history and/or test.
- Receipt of periodontal surgery or nonsurgical treatment within the last 6 months.
- Teeth with peri-apical pathology, acute abscess, or grade III mobility.

Deltakergruppe / Arm |
Intervensjon / Behandling |
|---|---|
|
Aktiv komparator: MINST alone
Participants receive the minimally invasive non-surgical technique (MINST) alone without adjunctive treatment
|
Subgingival debridement using thin ultrasonic tips and Gracey mini-curettes under magnification, deliberately avoiding subgingival rinsing to support blood clot stabilization
|
|
Eksperimentell: MINST + nano-hydroxyapatite
Participants receive MINST combined with the adjunctive application of nano-hydroxyapatite gel
|
Subgingival debridement using thin ultrasonic tips and Gracey mini-curettes under magnification, deliberately avoiding subgingival rinsing to support blood clot stabilization
A single dose of nano-hydroxyapatite (nHA) gel applied subgingivally directly into the periodontal pocket associated with the intrabony defect immediately following debridement

Patient Satisfaction
Tidsramme: 1, 3, and 6 months post-treatment.
|
Assessed via a structured questionnaire utilizing a Likert scale.
The scale ranges from 1 to 5, where 1 indicates "Very Dissatisfied" and 5 indicates "Very Satisfied," meaning higher scores represent a better outcome.

Assessed as a percentage (%) using the Visible Plaque Index (O'Leary et al.).
The index ranges from a minimum of 0% to a maximum of 100%.
Higher percentages indicate a greater presence of plaque, representing a worse clinical outcome.

The index ranges from a minimum of 0% to a maximum of 100%.
Higher percentages indicate more widespread gingival bleeding, representing a worse clinical outcome.
