Experimental Investigation of Dental Composites Degradation After Early Water Exposure
Abstract
International audience ; Abstract While dental composite long-term aging has already been studied in the past, no data exist about the early aging while it might be detrimental regarding the composites' longevity. This study aims to better understand the effects of early water exposure on dental composites. Dental resin composites with different fillers ratio were subjected to water exposure during 24h, 1 week, or 1 month. After photopolymerization, the samples were stored different conditions, whether in wet or dry condition (W, D, respectively) and in wet conditions after a first 24h storage in dry conditions (DW). Three-point bending tests were performed to measure the flexural modulus. The samples were then subjected to a sorption/desorption protocol. While the matrix alone did not undergo any mechanical degradation with exposure time, the composites matrices presented a decrease in elastic modulus. This decrease was the highest for the matrix with non-silanized fillers. Interestingly, the DW condition was detrimental for all the samples. Regarding the sample with non-silanized fillers in DW for 1 month presented an elastic modulus lower than the matrix alone. These results were assigned to the sorption capacity of the polymer matrix, suggesting that the diffusion mechanisms and the nature of water molecules are determinant in the composite degradation. This study showed that dental composite early degradation mechanisms after water exposure are involved in the polymer matrix post-polymerization process as soon as after 24h. Such mechanisms are detrimental in terms of the dental composite efficiency and have to be understood.
