Beskrivelse
Inclusion Criteria:
- Systemically healthy adults aged 18-65 years.
- No history of systemic diseases affecting periodontal status or bone metabolism (e.g., uncontrolled diabetes, osteoporosis).
- Diagnosed with Stage III periodontitis according to the 2018 classification of periodontal diseases (with interdental CAL ≥5 mm, probing depth ≥6 mm).
- Presence of at least one deep intra-bony defect (≥3 mm defect depth) in a single-rooted or multi-rooted tooth.
- Willingness to participate and sign informed consent.
Exclusion Criteria:
- Immunocompromised patients, uncontrolled diabetics (HbA1c ≥ 7.0%), or individuals with autoimmune disorders.
- 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.
- Multi-rooted teeth with class II and class III furcation defects.
- Third molars.

Intervention / BehandlingIntervention / 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
|
|
Eksperimentel: 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

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Clinical Attachment Level (CAL)
Tidsramme: 1, 3, and 6 months post-treatment.
|
Measured in millimeters (mm) using a manual periodontal probe (UNC-15).
|
1, 3, and 6 months post-treatment.
|
|
Gingival Recession (GR)
Tidsramme: 1, 3, and 6 months post-treatment.
|
Measured in millimeters (mm) using a manual periodontal probe (UNC-15).
|
1, 3, and 6 months post-treatment.
|
|
Radiographic Defect Angle (RDA)
Tidsramme: 1, 3, and 6 months post-treatment.
|
Measured in degrees (°) utilizing standardized periapical radiographs and measurement software.
|
1, 3, and 6 months post-treatment.
|
|
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.
|
1, 3, and 6 months post-treatment.
|
|
Full-Mouth Plaque Score (FMPS)
Tidsramme: 1, 3, and 6 months post-treatment.
|
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.
|
1, 3, and 6 months post-treatment.
|
|
Full-Mouth Bleeding Score (FMBS)
Tidsramme: 1, 3, and 6 months post-treatment.
|
Assessed as a percentage (%) using the Gingival Bleeding Index (Ainamo & Bay).
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.
|
1, 3, and 6 months post-treatment.
|
|
Cost Effectiveness based on Clinical Attachment Level (CAL)
Tidsramme: 6 months post-treatment.
|
Evaluated using the cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER), based on the cost in USD per millimeter (mm) of CAL improvement.
|
6 months post-treatment.
|
|
Cost Effectiveness based on Probing Pocket Depth (PPD)
Tidsramme: 6 months post-treatment.
|
Evaluated using the cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER), based on the cost in USD per millimeter (mm) of PPD improvement.
|
6 months post-treatment.
