Abstract
Purpose: This study investigated the electromyographic activity and clinical performance for teeth restored with Activa Bioactive Restorative with or without using a liner. Materials and Methods: A total of 40 posterior teeth were selected for this study and grouped into 2 main groups (20 for each group)) according to presence of caries in one or both side in patient (unilateral or bilateral). Each group was divided into two subgroups according to site of caries (Class I and Class II) (10 for each subgroup), each subgroup was restored with Activa Bioactive Restorative with or without Activa Bioactive Base/liner (5 for each). Before cavity preparation and after restoration (immediate, one week, three months and six months), masticatory muscles activity was evaluated by using electromyography and all restorations were evaluated by using modified USPHS criteria. The data were statistically analyzed with Kolmogorov- Smirnov and Shapiro-Wilk tests. Results: There was no statistically significant difference between masseter and temporalis muscles activities with soft and hard food in the two groups pre-operatively, immediately post-operative, after 1 week as well as after 3 and 6 months and there was no statistically significant difference seen in the clinical performance of Activa™ bioactive composite with or without a liner. Conclusion: Under the limitations of the study, there was no statistically significant difference seen in the clinical performance of Activa™ bioactive composite with or without liner at immediately post oprerative,1 week, 3 months, and 6 months, and it can be successfully be used to restore Class I and II carious lesions
