Clinical Trial Summary

Background: Alveolar osteitis is one of the most frequent complications after lower third molar extraction, and is usually accompanied by inflammation, pain and poor wound healing. Several local interventions have been used to reduce these complications with limited effectiveness.

Purpose: To clinically evaluate the use of propolis extract, nanovitamin C and nanovitamin E gel for the prevention of surgical complications related to impacted lower third molar extraction.

Methods: A randomized, triple-blind, split-mouth, pilot study is being performed in patients needing bilateral lower third molar extraction with similar surgical difficulty. Surgical extractions are randomly being performed and NBF gingival gel (TG) or placebo (PBG) are randomly being applied inside postextraction sockets by a blinded surgeon. The patients are being instructed to apply it 3 times/day in the surgical wound for 7 days. One month later, the contralateral wisdom tooth is being extracted and the opposite gel is being applied. Alveolar osteitis (AO) is being diagnosed following Blum's criteria. Swelling is being assessed by measuring the facial perimeter. Wound healing is being evaluated with a semi-quantitative scale as good, satisfactory or insufficient. Postoperative pain is being recorded using a visual analog scale (VAS) for 7 days. Analgesic pill intake is being recorded by each patient. Variables are being registered by a blinded researcher to 3M extractions at one, two, three and seven postoperative days.

Related Conditions & MeSH terms

• Alveolar Osteitis
• Dry Socket
• Osteitis

Intervention

Drug:
• NBF
Once the molar is extracted, the socket is cleaned with water, NBF gel is introduced, and the flap is closed. Then, the patients are instructed to apply NBF Gel in the surgical wound 3 times per day for 7 days after brushing their teeth. Previously they have to dry the area of the wound with gauze.

Device:
• Placebo
Once the molar is extracted, the socket is cleaned with water, placebo gel is introduced, and the flap is closed. Then, the patients are instructed to apply placebo gel in the surgical wound 3 times per day for 7 days after brushing their teeth. Previously they have to dry the area of the wound with gauze.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Alveolar Osteitis: intense neuralgic pain in the post-extraction socket in the second or third postoperative day that do not disappear with analgesics beside a partially or totally disintegrated clot	yes or no	from baseline to 24, 48, 72 hours post intervention
Secondary	Swelling: it was evaluated with a flexible metric tape measuring the facial perimeter from trago to pogonion. A first measurement was made before surgery, which was compared with the measurements taken at 24, 48 and 72 hours of the extraction.	changes	from baseline to 24, 48, 72 hours and 7 days post intervention
Secondary	Trismus: it was assessed measuring the maximum opening from the inter incisive points.	changes	from baseline to 24, 48, 72 hours and 7 days post intervention
Secondary	Wound healing: it was assessed with a semi-quantitative scale (good, satisfactory or insufficient).	changes	from baseline to 1 week post intervention
Secondary	Post extraction pain: it was recorded using a visual analog scale, ranging from 0 (no pain) to 10 (the worst pain imaginable) at 9 pm of 7 consecutive days.	changes	from baseline to 1 week post intervention
Secondary	Number of rescue analgesic pills consumption: recorded for the first 3 days by the patients.	number	from baseline to 3 days post intervention
