简要总结
Evaluation of the response of gingival tissues to the use of mouthwash with chlorhexidine and chlorhexidine + hyaluronic acid in terms of healing of the surgical wound following third molar surgery.
详细描述
Wound healing following third molar surgery will be evaluated at the level of the flap incision. Surgical interventions will be performed following a standardized protocol by a single operator.
After surgery, patients will be randomly assigned to study groups corresponding to mouth rinse prescription. The mouth rinse will be assigned by an experimenter not involved in the following steps of the study, in order to maintain the examiner blind. The patient will receive a non-labelled mouth rinse to avoid biases both of the examiner and the patient. The patient will also be given a diary for the registration of the number of rinses per day, to be returned to the examiner at T14. The mouth rinse protocol assigned to each study participant includes a 10 ml-rinse for 60 seconds twice-a-day (every 12 hours) for 14 days.
The patients will be allocated in one of the three distinct study groups as it follows:
Group A: administration of 0.2% chlorhexidine + anti-discoloration system + hyaluronic acid mouth rinse (test group 1) Group B: administration of 0.2% chlorhexidine + anti-discoloration system mouth rinse (test group 2).
Group C: administration of placebo mouth rinse (control group)

结局指标
主要结局
Wound Healing Index (WHI) (Wachtel classification)
时间窗: Measured at day 3, day 7, and day 14
Changes in WHI, measured orally through clinical examination on all the incisions, assigning a score from 1 to 5. Score 1: complete wound healing: absence of fibrin line in the interproximal area Score 2: complete wound healing: presence of a thin fibrin line in the interproximal area Score 3: complete wound healing: presence of fibrin clot in the interproximal area Score 4: incomplete wound healing: presence of partial necrosis of the interproximal area Score 5: incomplete wound healing: total necrosis of the interproximal area
