Surgical treatment of a cemental tear-associated bony defect using hyaluronic acid and a resorbable collagen membrane: a 2-year follow-up

Introduction A cemental tear (CeT) is a special type of surface root fracture that may cause periodontal and even periapical tissue destruction. Unfortunately, there is limited knowledge as to how these rare cases can effectively be treated. The present case is believed to be the first reported in the literature treating a bony defect caused by a cemental tear with hyaluronic acid (HA) and a collagen membrane.

Healing of intrabony defects following regenerative surgery by means of single-flap approach in conjunction with either hyaluronic acid or an enamel matrix derivative: a 24-month randomized controlled clinical trial

Objectives The aim of this randomized controlled clinical trial was to compare the clinical outcomes obtained in intrabony
defects following regenerative periodontal surgery using the single-flap approach (SFA) in conjunction with either hyaluronic
acid (HA) or enamel matrix derivative (EMD).
Materials and methods Thirty-two intrabony defects in 32 healthy subjects were randomly assigned: HA (test group) or EMD
(control group). Clinical attachment level (CAL), probing depth (PD), gingival recession (REC), and bleeding on probing (BOP)
