Cheng De-sheng
Abstract：BACKGROUND:Because ofgood performance, beautiful and permanent color, andcertain compressive strength,light-cured composite resinhas beenwidely used in dental restoration. Butthere are less reports about its usage inadultcrown restoration during orthodontic treatment. <br> OBJECTIVE:To explore the feasibility of light-cured composite resin in the adult crownres to rationduring orthodontic treatment. <br> METHODS:300 adultcases of crown defectss cheduled for orthodontic treatmentwere enroled, including 160 males and 140 females, aged from16 to 41years. Al the crown defects were filed with light-cured compositeresins. After 36-month folow-up, the gross appearances of repaired teeth,repairingeffect and adverse reactions were statisticaly recorded and analyzed. <br> RESULTS AND CONCLUSION:Afterrestoration, patients exhibited normal occlusion,and thefiled crowns were fixed stably and firmlywhose appearance was symmetric withthat of thecontralateral isonym tooth of the adjacenttooth.In addition, patients complainedofno percussion pain, and no apical shade was shownby X-ray examination.At the end of the folow-up,crown restoration was successful in268of 300 cases,with a success rate of 89.33%, andthe filed crowns fel out inthe other32cases;271of 300 cases were satisfied with therepairingeffect, and the satisfaction rate was 90.33%. Besides, there were no serious adverse reactions in al the patients. These results show that light-cured composite resinfor adultcrown restoration duringor thodontict reatmen to btains ahigherrepair success rate and satisfaction rate,withno serious adverse reactions.
