Clinical Assessment of Injectable Flowable Composite with Giomer Based Technology Versus Smart Bioactive Restoration in Carious Class V Cavities: An 18 month Randomized Clinical Trial

Background Bioactive materials can stop caries progression through releasing fluoride. The challenge in restoring cervical cavities is the dentin in the cervical margin where the high organic content and fluid movement in dentinal tubules make it a complicated structure. This study was carried out to evaluate the clinical performance of two different bioactive injectable flowable resin composite materials in restoring class V cavities over 18 months. Methods Thirty four participants with class V carious lesions were enrolled randomly. The participants were assigned into two groups (n = 17): Group (1) Beautifil Flow Plus X. Group (2) ACTIVA bioactive restorative. The modified USPHS criteria were used to evaluate ehe restorations at baseline as well as after 6, 12 and 18 months. Categorical data was described as frequency and percentage, the Chi-Squared test was used for intragroup comparisons between intervention and comparator while Cochran’s Q test was used for intragroup comparison in each group followed by multiple comparisons. Results There was no statistically significant difference in the intergroup comparisons in all the USBH criteria that was evaluated. Both groups revealed statistically significant differences in surface texture and anatomical form over different follow-up periods. Conclusions Both Beautifil flow plus X and ACTIVA bioactive have acceptable clinical performance in class V cavities after 18 months follow up period. Clinical Significance: Beautifil Flow Plus X injectable composite could be a promising material for restoring cervical cavities.
