Evaluation of Post-Operative Sensitivity of Bulk Fill Resin Composite versus Nano Resin Composite: A Randomized Controlled Clinical Study.

ABSTRACT: BACKGROUND:Despite recent advances in restorative dentistry adhesive restorations may cause postoperative sensitivity which leads to restoration failure. AIM:This study aimed to compare and evaluate the incremental and bulk fill resin Composite postoperative sensitivity in class II posterior restorations bonded with two adhesive systems (self-etch and etch-and-rinse). METHODS:Sixty patients were randomly selected, their age range from twenty-five to forty years old, divided into two groups according to the packing technique of resin composite material; incremental Tetric Evoceram and Tetric Evoceram bulk-fill resin composite. Thirty patients (n = 30) for incremental Tetric Evoceram resin composite restorations and according to the adhesive systems used they were equally divided (n = 15 teeth).Thirty patients (n = 30) for Tetric Evoceram bulk-fill resin composite restorations and according to the adhesive systems used (etch and rinse or self-etch), they were equally divided (n = 15 teeth). Post-operative pain assessed at 24 hours, 1 week and 1 month using the Visual Analog Scale Score (VAS). Each patient was instructed to put a mark on the VAS line at home to point out the intensity of pain at each assessment period. The problem of measuring the pain that pain tolerance of individuals may be different from the others. This may be due to different reasons, and it is not always because of a problem in the restoration. RESULTS:After 1 day, 1 week as well as 1 month, no statistically significant disagreement between the two resin composite types using self-etch adhesive strategy and total-etch adhesive strategy. Also, when the two adhesive systems were compared using Bulk Fill resin composite and incremental Nano resin composite no statistically significant disagreement between the two adhesive systems after 1 day, 1 week as well as 1 month. CONCLUSION:The post-operative hypersensitivity is related to many factors as the procedure of cavity preparation, adhesive approach, and type of resin composite used and placement technique of the resin composite.

Project description:Clinical studies are being conducted in less strict conditions in order to establish an adequate scientific basis for decision making. The aim of this pragmatic randomized clinical trial is to evaluate the effectiveness of single and multiple-surfaces restorations performed following the Atraumatic Restorative Treatment (ART) premises compared with Conventional Treatment (CT) using bulk fill composite restorations in primary and permanent teeth.A total of 1,214 5-to-13 year-old children with at least one single or multiple-surface dentin caries lesion in primary or permanent molars will be selected in public schools of Barueri-SP, Brazil. The participants will be randomly assigned into 2 groups: CT (caries removal with bur and restoration performed with Scotchbond™ Universal Adhesive system associated with Filtek Bulk Fill - 3 M/ESPE) and ART (Caries removal with hand instruments and restoration with high viscosity glass ionomer cement Ketac Molar Easy Mix - 3 M/ESPE). Ten untrained dentists will perform the treatment in in dental offices located at public schools. The restorations will be evaluated after 6, 12 and 24 months by an independent trained and calibrated examiner. The restoration and tooth survival, the cost-effectiveness analysis between the two groups and the operators' preferences regarding the techniques will be also evaluated. Kaplan-Meier survival analysis and log-rank test will be applied for the restoration and tooth survival. All the average event rates in the two groups will be modelled and compared with a Cox proportional hazard shared frailty model since there is an operator-cluster effect. The significance level for all analyses will be 5 %.Our hypothesis is that despite similar expected effectiveness between ART using high viscosity GIC and conventional treatment using bulk fill composite resin when treating single or multiple-surface in posterior primary and permanent teeth, ART will present superior cost-effectiveness. The results of this trial will support decision-making by clinicians and policy makers.NCT02568917 . Registered on May 10th 2015.
