Clinical and histological study for the effectiveness of lactic tactic in the extraction wounds

ABSTRACT

The polylactic acid surgical dressing material was used in fifty patients with bilateral soft tissue impaction, the right side as control group and the left side as study group. The results of this study showed that the polylactic acid has a significant ability to reduce the pain. On the other hand, the stability and the healthy condition of the blood clot was significantly obvious in the study group. Therefore the polylactic acid was significantly effective in the prevention of dry socket particularly in mandibular third molar wounds. Also in this study the experimental work was done in albino rat to show if the effect of this material on the sequence of healing of extraction wound and also to study any tendency for dry socket. The histological findings in the present work revealed that PLA dressing material significantly reduces the incidence of dry socket by supporting the wound's granulation tissue with available blood supply and in contact with that enhances new bone formation. Also this investigation showed that the rate of degradation PLA is very slow, but without any evidence of inflammation in one month study. So this can help very much in plastic surgery
