“…The adhesion at post-dentin and post-cement interfaces is also critical to avoid post-debonding, gap formation, and microleakage ( Alshahrani et al, 2020 ). As revealed in previous studies, incomplete polymerization of the resin cement increases shrinkage stress leading to post-debonding ( Ata et al, 2022 , Jamel, 2023 ). Conventional dual-curing resin cements have an acidic nature that protonates (tertiary amine) and prevents complete polymerization ( Lee et al, 2021 , Jitumori et al, 2023 ).…”

“…However, the pores occurred in fluoride diffusion are on the submicron scale (18,19). The expansion or contraction of micro-voids during the pressure cycle, due to pores and voids that may form during mixing, may cause deterioration and weakening of the cement layer (20). More studies are needed to evaluate the quantities and dimension of the air-voids and microcracks inside the cements.…”

“…Barodontalgia and barotrauma can mostly be seen at an altitude of 3000 m above sea level or over a depth of 10 m (3). Atmospheric pressure changes can influence the adhesion and durability of luting cements (2,(4)(5)(6)(7). Kielbassa et al (2018) assessed the impact of atmospheric changes on restorations (8).…”

Background and Purpose: The aim of this study was to evaluate the flexural strength values of five luting cements that are commonly used in dental restorations after exposed to hyperbaric pressure. Methods: Five luting cements (polycarboxylate cement, glass ionomer luting cement, manual-mixed resin cement, and two auto-mixed resin cement) were prepared. (25 x 2 x 2 mm3) (n=16 for each) The specimens were divided into two subgroups (n=8) and were exposed to hyperbaric pressure (3 ATM) 20 times for 30 minutes. The control groups stored in ambient pressure. Universal testing machine was used for flexural strength measurement with a crosshead speed of 1 mm/min. Results: One-way ANOVA test was used for statistical analysis, the differences in flexural strength values were additionally evaluated by Weibull Analysis. Glass ionomer and polycarboxylate cement were the most effected resins from hyperbaric pressure changes. Regardless of the pressure changes, the highest flexural strength values were seen for the self-adhesive resin cements and polycarboxylate cement showed the lowest strength value. Conclusion: Resin cements can be used for cementation of the dental restorations in divers and individuals who are subjected to hyperbaric pressure.

BACKGROUND: The purpose of this study was to evaluate the bond strength of fiber posts with different mixing methods and insertion into root canal techniques in long-term hypobaric pressure changes.METHODS: We chose and decoronated 42 teeth with straight and single root canals. After post-space preparation, the posts were cemented with hand-mixed and auto-mixed resin cements that were inserted into the canals with an endodontic file (lentilo), dual-barrel syringe, and root canal tip (14 for each group). After cementation, each group was divided into two subgroups (N = 7): the control (ambient pressure) group and the hypobaric pressure group. The samples were exposed to hypobaric pressure 90 times. They were cut into 2-mm-thick segments and the push-out bond strength test was performed using a Universal Testing Machine. One-way ANOVA tests, Bonferroni tests, and Student-t-tests were used for statistical analysis.RESULTS: The environmental pressure changes and insertion techniques affected the bond strength values. The auto-mixed with root-canal tip group showed the highest push-out bond strength values in both hypobaric (dual-barrel syringe group: 10.01 MPa; root-canal tip group: 11.61 MPa) and control (dual-barrel syringe group: 12.29 MPa; root-canal tip group: 14.58 MPa) group. In all root segments, the bond strength values of hypobaric groups were lower than atmospheric pressure groups. The most frequent failure type was adhesive between dentin and cement in all groups.DISCUSSION: Dentists should use auto-mixed self-adhesive resin with a root canal tip for post cementations in patients likely to be exposed to hypobaric pressure changes.Ozkan Ata S, Ata N, Yazgan E, Akkor T.
