Overview

This study is to assess the impact of implementing subepithelial connective tissue graft (SCTG) in the treatment of periodontal intrabony defects with Entire Papilla Preservation Technique (EPPT) on the clinical and radiographic results after 6 and 12 months.

Detailed description

This randomized controlled clinical trial aims to evaluate the clinical, radiographic, and volumetric outcomes of periodontal regenerative treatment using the Entire Papilla Preservation Technique (EPPT) with or without the addition of a subepithelial connective tissue graft (SCTG) in the treatment of intrabony periodontal defects.

Patients will be randomly assigned to receive EPPT combined with enamel matrix derivative (EMD) either with or without SCTG. Clinical, radiographic, and digital volumetric parameters will be assessed at baseline, 6 months, and 12 months to evaluate treatment outcomes.

Exploratory analyses will be conducted to assess the relationship between selected genetic polymorphisms (NLRP2 and IL-1β) and clinical outcomes of periodontal regeneration, including clinical attachment level, probing pocket depth, and gingival recession.

Interventions

  • Procedure Entire Papilla Preservation Technique (EPPT)
    A microsurgical periodontal regenerative technique aimed at preserving the interdental papilla. The procedure includes flap elevation, defect debridement, root surface conditioning, application of regenerative materials, and primary wound closure.
  • Other EDTA root conditioning
    Application of EDTA gel to the root surface to remove the smear layer and enhance regenerative outcomes.
  • Drug Enamel Matrix Derivative (EMD)- Emdogain
    A biologically active material applied to the root surface after EDTA conditioning to promote periodontal regeneration.
  • Procedure Subepithelial Connective Tissue Graft (SCTG)
    An autogenous connective tissue graft harvested from the palate and placed at the surgical site to enhance soft tissue thickness and stability.
  • Other Bone substitute - Bio Oss Collagen
    A xenogeneic bone graft material used to support bone regeneration within the intrabony defect.

Primary outcome measures

  • Clinical Attachment Level gain (CAL, mm) [Time frame: 6 months and 12 months]
Secondary outcome measures (12)
  • Probing Pocket Depth (PPD, mm) [Time frame: Baseline, 6 months and 12 months]
  • Probing Pocket Depth reduction (PPD, mm) [Time frame: 6 months and 12 months]
  • Clinical Attachment Level (CAL, mm) [Time frame: Baseline, 6 months, and 12 months]
  • Gingival Recession (GR, mm) [Time frame: Baseline, 6 months and 12 months]
  • Keratinized Tissue Width (KTW, mm) [Time frame: Baseline, 6 months and 12 months]
  • Gingival Thickness (GT, mm) [Time frame: Baseline, 6 months and 12 months]
  • Soft Tissue Volumetric Change (mm³) [Time frame: 6 months and 12 months]
  • Radiographic Linear Defect Fill (LDF, mm) [Time frame: 6 months and 12 months]
  • Radiographic Percentage Defect Fill (%DF) [Time frame: 6 months and 12 months]
  • Early Wound Healing Score (EHS) [Time frame: 1 week and 2 weeks]
  • Full-Mouth Plaque Score (FMPS, %) [Time frame: Baseline, 6 months, and 12 months]
  • Full-Mouth Bleeding Score (FMBS, %) [Time frame: Baseline, 6 months, and 12 months]
