Comparision of the clinical effects of glass-fiber post on endodontically treated anterior teeth with varying ferrule heights and configurations

Objective To study the clinical effects of glass-fiber post on anterior teeth with varying ferrule heights and configurations.To compare the clinical effects of glass-fiber post following surgical crown lengthening or not on severe anterior teeth defect.Methods 295 anterior teeth with varying ferrule heights were divided into Ⅰ、Ⅱ、Ⅲdegree teeth defects.All teeth were divided into five groups:A、B、C、D、E.Group A:62 teeth with Ⅰdegree defect;Group B:77 teeth with Ⅱdegree defect;Group C:59 teeth with Ⅲdegree defect;Group D:48 teeth with Ⅲ degree defect;Group E:49 teeth withⅢ degree defect;The groups of A、B、C、D were restored with glass-fiber post;The teeth of group E gained ferrule no less than 2mm following surgical crown lengthening and were restored with glass-fiber post.Results The success rates of group A、B、C、D、E were 100%、100%、96.6%、85.4%、97.9%respectively.The difference between A、B;A、C;A、E;B、C;B、E;C、E was not significant(P0.05).The difference between D、E was significant(P0.05).Conclusions The clinical effect of glass-fiber post was satisfying in the restoration of anterior teeth defect,with ferrule no less than 2mm.Glass-fiber post crown restoration following surgical crown lengthening could effectively restore severe anterior teeth defect.
