Objective To explore the effect of red lip defect repair using orbicularis oris muscles pedicle island flap disc.Methods 100 cases of unilateral pure red lip defect 1/3-2/3,lip lines full of patients were selected as the research subjects.They were randomly divided into two groups,50 cases in each group.Group A treated with debridement surgery to repair.Group B received red lip flap to promote repair treatment.The treatment effect of the two groups, satisfaction, lip survival rate and the degree of obvious scars were compared.Results he operation effect of the two groups was good.The satisfaction rates of group A and group B were 94.00% and 96.00%,respectively.For the lip shape treatment satisfaction, the difference was no statistically significant (P>0.05).The patients of the two groups with lip all alive, and 1 patient in group A with obvious scar, the scar was not obvious in group B.Conclusion For patients with red lip defect, take orbicularis oris muscles pedicle island flap of the oral mucosa or red lip flap to promote repair treatment has relatively significant clinical efficacy, with easy operation, less influence on the patients with facial form, it is worthy of popularizing.

Objective To analyze the living polymerization porcelain inlay restoration dental pulp large clinical efficacy of dental defects and infection prevention. Methods Forty-two cases patients with dental defects after the live pulp tooth of large teeth 48, were randomly divided into experimental group (24 teeth) and the control group (24 teeth). The experimental group tooth preparation, polymerization porcelain inlay restoration; Control group metal ceramic crowns, resin adhesive application RelyX Unicem 2-year follow-up and evaluated of the efficacy analysis infection prevention methods. Results The color matching, shape matching, secondary caries, marginal fit, wear and fracture strengths in the experimental group were better than the control group, the difference was statistically significant (P<0.05). Conclusion Living polymerization porcelain inlay restoration dental pulp excellent clinical efficacy large area of dental defects, pa-tients followed up show functions fine roles in shape, color matching after 2 years.
