Periodontal Regeneration With Hyaluronic Acid or Enamel Matrix Derivatives

Minimally invasive flap elevation and debridement of the intrabony defect with micro-curettes. Root surface debridement with ultrasonic debridement with periotip and mini-curettes. Application of cross-linked hyaluronic acid gel composed of a mixture of cross-linked (1.6%) and natural (0.2%) hyaluronic acid (hyaDent BG, Regedent, Germany) through a syringe over a bone xenograft (Smartgraft, Regedent, Germany). The mixture will be then compacted within the intrabony component of the defect.

Minimally invasive flap elevation and debridement of the intrabony defect with micro-curettes. Root surface debridement with ultrasonic debridement with periotip and mini-curettes. Enamel matrix derivatives gel (Emdogain, Straumann, Switzerland) will be applied on the dry root surfaces and left in place for at least 1 minute avoiding blood contamination. Subsequently, a bone xenograft (Smartgraft, Regedent, Germany) will be compacted within the intrabony component of the defect.
