Influence of irrigation and laser assisted root canal disinfection protocols on dislocation resistance of a bioceramic sealer

The present study aimed to investigate the possible use of a non-instrumentation technique including blue light irradiation for root canal cleaning. Extracted human single rooted teeth were selected. Nine different groups included distilled water, NaOCl, intra-canal heated NaOCl, and NaOCl + EDTA irrigation after either instrumentation or non-instrumentation, and a laser application group following non-instrumentation technique. The chemical assessment of the root canal dentine was evaluated using energy dispersive spectroscopy (EDS) and Fourier transform infrared (FT-IR) spectroscopy. Surface microstructural analyses were performed by using scanning electron microscopy (SEM). The antimicrobial efficacy of different preparation techniques was evaluated using microbial tests. Light application didn’t change the calcium/phosphorus, carbonate/phosphate and amide I/phosphate ratios of the root canal dentin. The root canal dentin preserved its original chemistry and microstructure after light application. The instrumentation decreased the carbonate/phosphate and amide I/phosphate ratios of the root canal dentin regardless of the irrigation solution or technique (p < 0.05). The application of light could not provide antibacterial efficacy to match the NaOCl irrigation. The NaOCl irrigation both in the non-instrumentation and instrumentation groups significantly reduced the number of bacteria (p < 0.05). The use of minimally invasive root canal preparation techniques where the root canal is not instrumented and is disinfected by light followed by obturation with a hydraulic cement sealer reduced the microbial load and preserved the dentin thus may be an attractive treatment option for management of vital teeth needing root canal therapy.

Background: Dentin adhesion is a basic aspect to consider in a root canal sealer. Calcium silicate-based cements are materials that have excellent biocompatibility and bioactivity. Bioactivity is closely related to dentin bond strength. One of the tests that is most used to evaluate the adhesive property of a sealing cement is the “push-out bond strength” test, which consists of applying tensile forces to the root to measure the resistance of the bonding of a material to root dentin. Aim: The aim of this systematic review is to perform a qualitative synthesis of available evidence on the adhesion of calcium silicate-based sealers to dentin. Methods: An advanced search of the literature was performed in five databases, limited to in vitro studies on human teeth published in the last 5 years. Results: 42 studies were eligible for the review, and data were collected according to the number of teeth studied, the canal preparation, the irrigant used, the mechanical test used, the root thirds and the type of sealer studied. A qualitative synthesis of the evidence is presented. Conclusions: TotalFill BC sealer and EndoSequence Root Repair Material appear as the calcium silicate-based materials with the highest bond strength to dentin. In addition, using 17% EDTA as a final irrigant increases the bond strength of calcium silicate-based sealers.
