“…The obtained results for temperature changes associated with light-curing of the Filtek Bulk Fill Posterior are in accordance with previous studies reporting on other bulk-fill composites and cavity designs [29][30][31]. Bulk-fill composites, when tested in a water bath at 36-37 °C showed temperature increases in the pulp chamber ranging from 2.8 °C in primary [29] to 5 °C in permanent molars [31]. A flowable bulk-fill composite in deep cavities with the 0.5 mm remaining dentin thickness without a liner resulted in temperature changes up to 40 °C at the pulp dentin even though the material itself showed temperatures exceeding 50 °C at the bottom of the restoration [30].…”

The objective of this study was to measure temperature changes in the pulp chamber induced by polymerization of resin-based dental restoratives following a simulated procedure of direct pulp capping. Class I cavities with a microperforation at the pulp horn were prepared in extracted human molar teeth. The complete procedure of direct pulp capping and cavity restoration was performed with the root part of extracted teeth fixed in a water bath at 37 °C. Mineral trioxide aggregate, bioactive dentin substitute or calciumhydroxide paste were used as pulp capping materials. Cavities were restored with a lightcured or chemically-cured resin-modified glass ionomer, universal adhesive and a bulk-fill composite, cured with a high-intensity LED unit. Pulp capping materials caused a slight temperature decrease. Lower temperature increase was recorded during light-curing of the glass ionomer liner after direct capping with mineral trioxide aggregate and calciumhydroxide than that recorded for the bioactive dentin substitute. Adhesive light-curing increased temperature in all groups with higher mean temperatures in groups with chemically-cured as compared to those for the light-cured glass ionomer liner. Direct pulp capping with mineral trioxide aggregate or calcium-hydroxide followed by the light-cured resin-modified glass ionomer liner and a bonded bulk-fill composite restoration induced temperature changes below the potentially adverse threshold of 42.5 °C.

“…High-viscosity bulk-fill composites 2 of 10 (such as QuixFil, Dentsply, Konstanz, Germany) can be used to fill cavities entirely with only one material up to the occlusal surface, whereas low-viscosity bulk-fill composites (such as SureFil SDR flow, SDR, Dentsply) equate a final capping layer by a regular hybrid composite material because of inferior mechanical properties towing to their reduced filler load and filler composition [7,8]. It was shown that bulk-fill RBCs had the lowest shrinkage stress and shrinkage-rate values in comparison to regular flowable and non-flowable nanohybrid and microhybrid methacrylate-based RBCs and a silorane-based microhybrid RBC and do not increase the intrapulpal temperature in primary teeth during the curing/setting [9][10][11][12]. They were also able to reduce cuspal deflection in standardized Class II cavities compared with a conventional RBC (GrandioSO, VOCO, Cuxhaven, Germany) restored in an oblique incremental filling technique [5,8].…”

Background: The aim of this split-mouth study is to compare the results of 24 months’ clinical performance of primary molar Class I restorations with a nano-ceramic composite, Ceram•X mono (Dentsply) with a flowable bulk-fill material regular viscosity, SDR (Dentsply). Methods: Following the ethical approval, 27 patients with at least two class I cavities in primary molars were included in the study. A total number of 54 restorations were conducted (n = 27 for Ceram X and n = 27 for SDR). Restorations were evaluated at baseline, 6, 18, and 24 months, according to the modified Ryge criteria. The cavosurface marginal discoloration and color match were evaluated visually after air-drying the tooth and after removing the plaque (if necessary). Results: At 24 months’ follow-up, 54 restorations showed similar clinical performance. The statistical analysis did not reveal any statistical significance in the values between the groups in 7 out of 7 modified Ryge criteria. However, two restorations in both groups received Bravo ratings in the cavosurface marginal discoloration scoring. No side effects were reported by the participants of the study. Conclusion: Restorations with both materials (Ceram•X mono and SDR) have provided almost identical results.

“…Resin based composites are universally used for all types of cavities in anterior and posterior teeth. They are considered to be the main option of countless dentists in direct restoration of carious lesions, because of their advantages as high strength, low thermal conductivity, modulus elasticity, hardness [1,2]. However, the drawbacks of this material are well known among the practitioners.…”

“…In literature microleakage is defined as the clinically undetectable passage of bacteria, fluids, molecules or ions between a cavity wall and the restorative material [4][5][6][7]. Therefore the bulk-fill composites have been developed, in order to minimize the time of work required by the incremental techniques and decrease micro-leakage [2,4].…”

This study evaluates and compares by dye penetration method and SEM photomicrographs the sealing obtained using two different classes of adhesive systems (etch-and-rinse and self-etch with selective etching) with SDR (Dentsply) bulk fill composite. 84 class V cavities were prepared on oral and vestibular face of 42 intact, freshly extracted wisdom teeth. The cavities were randomly divided in two groups and restored: Group 1 with prime &bond one select (Dentsply) and SDR (Dentsply) and Group 2 with prime&bond one Etch&Rinse (Dentsply) and SDR (Dentsply). Prime&bond one Select (Dentsply) is a single component adhesive and can be used in self etch mode, in selective enamel etch mode, or in etch-and-rinse mode. We chosen for this study the selective etch of the enamel mode. Prime&bond one Etch Rinse (Dentsply) is a universal etch-and-rinse one-bottle dental adhesive, designed to be used in two steps. The bulk fill composites are commonly used in modern dentistry due to their properties of low polymerization shrinkage and curing in layer of 4 mm depth, offering the practitioner a fast clinical procedure with good results. The results showed a good sealing at enamel and dentin margins with no statistically significant difference between adhesives, even though the mean of enamel infiltration was smaller for Group1. Furthermore the results show that there were differences between the two groups, for the infiltrations at the enamel, the values of microleakage being arithmetically higher for Group 1, but with no statistically difference between the two groups.SEM images showed for both groups a good adhesion surface with the tooth, but the hybrid layer of the total-etch adhesives is different from the hybrid layer formed by self etch adhesives, in terms of thickness, uniformity. In conclusion both adhesive systems have equivalent sealing qualities and can be successfully used with SDR.
