Abstract:

BACKGROUND: Light-cured composite resin is used for dental crown defective repair in terms of both function and morphology.
OBJECTIVE: To investigate the therapeutic effects of light-cured composite resins on crown defects.
METHODS: Relevant literatures concerning light-cured composite resins for repair of crown defects were retrieved. Literatures which met the study standard were deeply analyzed. Meanwhile, follow-up results and literature results were compared for patients receiving light-cured composite resins for repair of crown defects to identify the feasibility of light-cured composite resins for repair of crown defects.
RESULTS AND CONCLUSION: Based on the included data, the successful rate of light-cured composite resins for repair of crown defects was over 90%. Clinical follow-up of 12 patients undergoing light-cured composite resin showed that the repaired crowns were stable and fixed, and exhibited a symmetrical appearance with the contralateral namesake tooth of the adjacent tooth, and there was a normal bite relationship. During the follow-up study, 19 teeth repaired from 12 patients had no loosing, no shedding, no percussion pain and normal bite relationship. X-ray films showed no apical shadows. Light-cured effects were limited to the upper and middle parts but not to the apical part. Therefore, a better therapeutic effect can be obtained.
