In the group of teeth restored with BisBlock postoperative sensitivity was observed in 6.7% restorations, while in the group where desensitizer was not used, sensitivity was noted in 15.8% of cases. Results Teeth restored using Calcimol LC were the most sensitive after treatment whereas teeth restored with Fuji II LC showed the least postoperative sensitivity (Calcimol LC > ANA Liner > Fuji II LC). The following liners were used: Calcimol LC, ANA Liner, Fuji II LC desensitizer: BisBlock and composite material: Ceram-X Mono. In each patient, before the application of composite material in one tooth the liner was placed, while in the other tooth both the desensitizer and the same linerwere used. Patients were divided in three groups, depending on applied liner. ![]() Material and Methods This clinical study included 120 patients in which two homologous contralateral posterior teeth were restored with composite material and different liners. ![]() The aim of this study was to examine the clinical efficacy of different liners and oxalate-based desensitizer in preventing the occurrence of postoperative sensitivity. Abstract: Introduction Despite the development of restorative dentistry bond between materials and hard dental tissues is still not satisfying and often leads to marginal discoloration, microleakage, secondary caries and postoperative sensitivity.
