Objectives The aim of study is measurement of in vitro intrapulpal temperature increase when placing room temperature or preheated (54°C and 60°C) bulk‐fill composite. Materials and methods Extracted human lower third molars were selected and class II (MOD) cavities in each tooth were prepared, resulting in a remaining dentin thickness of 1 mm. A K‐type thermocouple was placed inside the pulp chamber. Teeth were placed in a 37°C bath, which simulated human body temperature. Teeth were restored with a bulk‐fill composite that was stored at room temperature and preheated at 54°C and 60°C. Data were subjected to two‐factor mixed‐design analysis of variance using a general linear model procedure for repeated measurements. Results Stage, composite temperature, and stage‐composite temperature interaction significantly affected the intrapulpal temperature values (P < .001). Conclusions Preheating does not represent significant problems in terms of intrapulpal temperature increase. Even Though the preheating process results in an increase in intrapulpal temperature, this temperature increase is not the critical factor that causes harm to the pulp. Clinical Significance Preheating can improve material features. Benefits of improved material features are desirable to practitioners. Temperature increase is not the critical factor that harms to the pulp even if the preheating process can result with an increase in intrapulpal temperature.

Aims: This study aimed to evaluate the effect of preheated nanoceramic resin-based composite (RBC) (Ceram-X-Mono) placed in Class I occlusal cavities over a period of 18 months. Settings and Design: This study involves split-mouth design, randomized controlled clinical trial (RCT) Materials and Methods: One operator restored 60 Class I occlusal cavities in 24 patients. Preheating of nanoceramic RBC to 60°C for 10 min was performed before insertion of the material into 30 prepared cavities, whereas 30 restorations in the nonpreheated group were placed according to the manufacturer's instructions. Two observers evaluated the restorations using Federation Dentaire Internationale (FDI) criteria at baseline, 6, 12, and 18 months. Statistical Analysis: Kappa index, Friedman and Wilcoxon matched pair test, and Krushal-Wallis and Mann-Whitney tests were used for statistical analysis. Results: 100% retention rates were seen in both the groups. In nonpreheated group, significant difference was observed for surface staining ( P = 0.0001), color stability ( P = 0.0277), anatomic form ( P = 0.0431), and marginal adaptation ( P = 0.0051), whereas in preheated group, significant increase in surface staining ( P = 0.0051) was recorded. There was a statistically significant difference observed between the preheated and nonpreheated groups at different time periods for the tested clinical parameters. Conclusion: Within the limitations of this RCT of 18 months, preheated nanoceramic RBC restorations showed better clinical performance compared to nonpreheated group.

“…It found that preheated resin composite to 54°C or 68°C increased the intra-pulpal temperature than the composite that was applied at room temperature but not to the critical level. The elevation was 1.5°C-2°C (18).…”

“…In Group III with the compothixo packing instrument, the vibration seemed to make the material more adherent to the instrument and more difficult to apply due to the high viscosity of bulk fill material leading to the poor adaptation between restoration and cavity walls. A variety of studies have shown that lower viscosity of composites can improve adaptation and reduce microleakage (18)(19)(20)(21)(22). In contrast to our results, Eunice et al (9), evaluated the marginal microleakage with SonicFillTM.…”

INTRODUCTION: Different placement techniques of resin-based composite (RBC) systems have been developed to improve the marginal adaptation and reduce microleakage. These techniques included preheating and vibration of resin composite materials. OBJECTIVES: The current study aimed to investigate the effect of preheating and placement techniques on microleakage and marginal gap formation of class V composite restorations. MATERIALS AND METHODS: A total of eighty sound extracted human molars were used in this study. Standard class V cavities were prepared on their buccal surfaces (4mm mesiodistally, 3mm occlusocervically, and 3 mm pulpal depth). The teeth were divided into 4 groups (n=20): Group I: restored with Filtek bulk fill flowable composite, Group II: restored with Filtek bulk fill composite after it was heated to 60°C using Calset device, Group III: restored with Filtek bulk fill composite adapted with a vibrating instrument (Compothixo), Group IV: restored with Filtek Z350 XT. Specimens were light cured, thermocycled between (5 ºC and 55 ºC in water) and marginal gaps assessment was measured under a stereomicroscope and measured in micrometers. Then teeth were dyed with 0.5% basic fuchsin dye for 24 hours. The dyed specimens were sectioned in the buccolingual direction and evaluated for microleakage (dye penetration) using a stereomicroscope. RESULTS: For marginal gap assessment, results revealed a significant difference between the tested groups, where flowable bulk-fill showed the lowest statistically significant marginal gaps compared to other groups at the occlusal and gingival margins (p<0.05). For the microleakage test, the groups showed more microleakage at gingival margins compared to occlusal margins, flowable bulk-fill and preheated bulk-fill showed the lower microleakage scores among groups. CONCLUSIONS: None of the placement techniques produced gap-free margins. Flowable bulk-fill composite and preheated composite preserved better marginal integrity and reduced microleakage.
