“…11,28,31,56 However, a recent systematic review stated that reported PH-RC film thicknesses were higher than the DC-ARC one's. 8 The current study has demonstrated that the pre-heating of conventional composites to 55 C does not produce lower values of film thickness than those produced by the dual-cured resin cements at room temperature, even when handled by an expert. As a result, the first null hypothesis of no difference between the film thickness of DC-ARC and PH-RC, independently of the operator's expertise, must be rejected.…”

“…The viscosity of resin composites affects their ease of handling and finally the thickness of the film after polymerization. 8,16,[28][29][30][31] Previous studies have shown that the composition of composite resins is one of the major factors affecting their viscosity and consequently their film thickness. 16,22,48,54 Thus, the highly filled composites tend to flow less and to therefore form thicker films.…”

“…1,2 However, the interest in rather using pre-heated resin composite (PH-RC) for this purpose is constantly growing. [3][4][5][6][7][8] This clinical option, which was proposed earlier in 1998, 9 is based on the fact that pre-heating resin composites improves their physical properties as it has been demonstrated for direct restorations. [10][11][12] While pre-heating DC-ARC is reported as clinically nonefficient, [13][14][15] several studies reported that the use of PH-RC provides various advantages compared to the resin cement, including: (1) better mechanical properties due to their fillers; (2) better color stability due to the absence of tertiary amine in their composition; (3) increased choice of colors; (4) ease of manipulation and ease of polishing.…”

Objective: There is a growing interest in using pre-heated composites instead of dual-cured cements when luting indirect restorations. This study evaluated the film thickness obtained from two pre-heated composites and two resin cements, by two different operators. The influence of the materials and the level of expertise of the operator were analyzed.Materials and Methods: Forty specimens of human dentin and composite discs were prepared and divided into four groups depending on the luting process. Each group was randomly equally divided to be handled by two operators with different levels of experience. Two of the initial four groups were luted using dual-cured cements and the two remaining groups using light-cured pre-heated composites. Specimen discs were cut after luting, and film thickness was measured using a Digital microscope.Data were analyzed using a 2-way ANOVA with the Holm-Sidak pairwise multiple comparison procedure (p < 0.05).Results: Mean film thickness ranged from 156.16 ± 4.7 to 33.82 ± 0.7 μm. Significant differences (p < 0.001) were noticed between expert and novice results with preheated composites. Conclusion:Within the limits of this study, using pre-heated composites as a luting cement requires a better level of expertise to achieve a clinically acceptable film thickness.Clinical Significance: Using pre-heated composites as luting agent for indirect restorations requires an experimented skill level to achieve a clinically recommended film thickness.

“…Regarding the inorganic composition, commercially available resin-matrix cements contain an inorganic content ranging from 57 up to 78 wt% [ 13 , 14 , 19 , 55 , 56 , 57 , 58 , 59 , 60 ]. As shown in Table 1 , colloidal silica, ytterbium, or barium glass are the most frequent inorganic particles used as fillers [ 19 , 61 ].…”

“…However, other combinations of fillers have also been used, such as fluoroaluminoborosilicate glass, strontium calcium aluminosilicate glass, quartz, or other glass fillers [ 13 ]. The inorganic filler content is responsible for enhanced mechanical properties, although resin-matrix cements usually have a lower filler content when compared with resin-matrix composites [ 58 , 61 ]. Resin-matrix cements reveal a high variability in shape, size, and content of inorganic filler particles [ 56 ].…”

A Scoping Review on the Polymerization of Resin-Matrix Cements Used in Restorative Dentistry

In dentistry, clinicians mainly use dual-cured or light-cured resin-matrix cements to achieve a proper polymerization of the organic matrix leading to enhanced physical properties of the cement. However, several parameters can affect the polymerization of resin-matrix cements. The main aim of the present study was to perform a scoping review on the degree of conversion (DC) of the organic matrix, the polymerization, and the light transmittance of different resin-matrix cements used in dentistry. A search was performed on PubMed using a combination of the following key terms: degree of conversion, resin cements, light transmittance, polymerization, light curing, and thickness. Articles in the English language published up to November 2022 were selected. The selected studies’ results demonstrated that restorative structures with a thickness higher than 1.5 mm decrease the light irradiance towards the resin-matrix cement. A decrease in light transmission provides a low energy absorption through the resin cement leading to a low DC percentage. On the other hand, the highest DC percentages, ranging between 55 and 75%, have been reported for dual-cured resin-matrix cements, although the polymerization mode and exposure time also influence the DC of monomers. Thus, the polymerization of resin-matrix cements can be optimized taking into account different parameters of light-curing, such as adequate light distance, irradiance, exposure time, equipment, and wavelength. Then, optimum physical properties are achieved that provide a long-term clinical performance of the cemented restorative materials.
