摘要: Despite improvements in composite treatments over the past decade, postoperative sensitivity still remains a problem. Therefore, this clinical study evaluated appearance of after and stimuli that may have caused it. A total 600 teeth 231 patients was included study. All were performed by dental students working under close supervision following standard procedures using bonding system Optibond FL nanofilled Ceram X. At baseline (visit 1), restorations grouped according to criteria: use anesthesia, rubber dam, indication for restoration treatment, cavity class dimension cavity. After approximately two weeks (at visit 2), all assessed failure defined if one criteria occurred: negative reaction vitality test, pain from masticatory forces or reported patient. The specified with visual analogue scale into hot/cold-sensitivity, sweet/soursensitivity, sharp/dull-sensitivity, spontaneous blistering/stinging-sensitivity. Failure observed 6% restorations. statistical analysis showed depth turned out be only factor significant influence on sensitivity: caries profunda four times higher risk failure, while cavities pulp exposure had 14 compared localized dentin. With regard type sensitivity, no sweet/sour; most them described their as sharp/dull.
