This paper is intended to offer a theoretical basis for clinical appliance of preheating by comparing the properties of six different resin composites at room temperature and pre-heated temperature. The experiment is divided into two groups: one at room temperature (20 , the other at preheated temperature (60 ). At room temperature, the six resin composites were exposed to a LED light for 20 seconds. While in the other group, the resins were firstly put into an incubator which is elevated to 60 , and then taken out. After 60 seconds, they were exposed to LED light for 20 seconds. In each group, the compressive strength, micro Vickers hardness and the degree of conversion of six resin composites were tested. After being filled with resin composites, the extracted teeth were dyed and sliced. The microleakage of the restoration was observed and then recorded. All the data was analyzed by statistical analyses. Preheating has no apparent effect on compressive strength, hardness and degree of conversion of Filtek TM Z350, Surefil, Solitaire2, ESTELITE , BRILLIANT New Line, but significantly improved the compressive strength and the hardness of GRADIA DIRECT. And preheating also reduces the microleakage of resins, especially for Surefil and Solitaire2. Preheating has effect on the properties of resin composites, and different resins differ in the sensitivity to preheating due to their different components and contents. In clinical, we ought to fully consider the value of preheating according to requirement in order to obtain the benefit.

“…11 Composite resin preheating to 60°C prior to resin polymerization decreases the resin viscosity and allows for an increased free radical mobility. [12][13][14][15] Consequently, these materials achieve higher monomer conversion at high temperature than when they are achieved at room temperature. 12,13,[16][17][18] When monomer conversion is closely related to the polymer mechanical properties, [19][20][21] improved bond strength of indirect restorations to dentin would be expected even when LA polymerization relies solely on selfcuring components.…”

This study evaluated the effects of resin luting agents (LA) polymerized using increased temperature on the in vitro microtensile bond strength (µTBS) of indirect restorations to dentin. The occlusal dentin surfaces of 40 human third molars were exposed and flattened. The teeth were assigned to 8 groups (n = 5) according to the LA temperature (25°C or 50°C), curing mode (dual-or self-curing mode), and product (Excite DSC / Variolink II [VII] and XP Bond / Calibra [Cal]). The bonding agents were applied to the dentin surfaces according to manufacturers' instructions. For preheated groups, the LAs were heated to 50°C, subsequently mixed on a heated stirrer surface, and applied to the previously heated pre-polymerized resin discs (2 mm thickness, TPH-Spectrum). The discs were bonded to the dentin surfaces, and the LAs were either exposed to a curing light according to manufacturers' instructions or allowed to self-cure. Specimens were stored in relative humidity at 37°C for 7 days. Specimens were mesio-distally and bucco-lingually sectioned to obtain multiple bonded beams with a 1-mm 2 cross-sectional area for µTBS testing. Data (MPa) were analyzed by 2-way ANOVA and Tukey's post hoc test (α = 5%) for each product. Specimen failure patterns were analyzed using a scanning electron microscope. VII groups showed higher µTBS at 50°C than at 25°C regardless of curing mode (p = 0.05). Cal groups showed similar µTBS at 25°C and 50°C in all activation modes. The use of some dual-polymerizing LAs at 50°C may improve the µTBS of indirect restorations to dentin.

“…[5] Film thickness, which is normally limitation with restorative composites resins, can be resolved using preheating. [3][4][5][6]13,22,26,46,48] When using EMAX, group E presented a stable SBS values after aging but was still significantly inferior to that of E/S+. This emphasizes the synergetic effect of etching and silane on that specific ceramic.…”

Abstract:Aim:Evaluate surface treatments and silane application methods and their effect on shear bond strength (SBS) before and after aging. Materials and methods. Slices of IPS e.max CAD and Vitablocs Mark II, were embedded in acrylic resin. The block was randomly assigned to 5 groups; E:etching with hydrofluoric acid (HF), rinsing, followed by cleaning in ultrasonic bath; E/S:HFetching and cleaned as group E followed by silane application for 20s, air drying and hot drying; E/S+:HFetching and cleaned as group E, followed by silane application for 60s, air drying and hot air drying, rinsing with boiling water and hot air drying; S:silane application for 20s followed by air drying and hot air drying; S+:silane application for 60s followed by air drying, air drying and hot air drying, rinsing in boiling water and hot drying. Cylinders of composite resin (n=12) were bonded with adhesive. SBS testing was carried out after 24h or after thermocycling for groups E; E/S and E/S+. Results. For 24h SBS showed sign
