Abstract:Objective To investigate the advantages and disadvantages of Glass ion and composite resin combined repair or repair alone in wedge-shaped defect.Methods Ninety wedge-shaped defect cases in our hospital from August 2015 to October 2016 were retrospectively analyzed,altogether 254 teeth.254 teeth were randomly divided into three groups according to the operation time.85 teeth in group A were filled with glass ions.89 teeth in group B were filled with composite resin.80 teeth in group C were filled with glass ions and composite resin.The dental pulp vitality,periodontal tissue stress and therapeutic effect before treatment and after treatment for 1 year were observed among the groups.Results There was no significant difference in pulp vitality between the three groups before treatment(P>0.05).The percentage of normal pulp in group C(91.3%)was significantly higher than that in group A(69.4%)and B(69.7%)after treatment for 1 year,the difference was statistically significant(P<0.05).The percentage of dental pulp degeneration in group C(1.2%)was significantly lower than that of group A(22.4%)and B(22.5%),the difference was statistically significant(P<0.05).There was no significant difference between the A groups and B(P>0.05).Conclusion The combination of glass ion and composite resin to repair wedge-shaped defects can effectively prevent the filler from falling off,protect the pulp,reduce periodontal stress.It is better than single use,which is worthy to clinical promotion.
