Abstract:

BACKGROUND: Few reports are found with J-1 acellular dermal matrix to prevent postoperative complications after impacted mandibular third molar extraction.
OBJECTIVE: To evaluate the effects of acellular dermal matrix embedded in socket after wisdom tooth extraction.
METHODS: 400 patients with impacted mandibular third molar were divided into two groups at random with 200 in each group. In group A, the acellular dermal matrix was embedded in the sockets after wisdom tooth extraction; group B was the blank control. Postoperative complications of the two groups were observed after treatment.
RESULTS AND CONCLUSION: No acellular dermal matrix lost from wisdom tooth extraction sokets. Blooding after tooth extraction decreased when acellular dermal matrix was embedded in the sokets, hemorrhage incidence rate was lower in group A than in group B. Acellular dermal matrix could prevent blood clot lose from sockets, and also can prevent food residual entering into the sockets. Dry socket incidence rate was lower in group A than group B. Acellular embedded in the sockets had no effects on swelling incidence rate. Acellular dermal matrix embedded in socket after tooth extraction can prevent dry socket and hemorrhage, but can not prevent swelling.
