“…In the present study, fibreglass posts were customized due to the large diameter of the root canals of the simulated immature teeth. Customization of fibreglass posts aimed at avoiding a thick‐resin cement layer 18,19 . The presence of gaps and voids in thick‐resin cement layers is more common than in thin‐resin cement layers.…”

“…It may compromise the longevity of luted fibreglass posts. 18,19 Of note is that RelyX Ultimate resin cement was used in the total-etching mode. Ubaldini et al 18 reported that RelyX Ultimate creates a deep and wide zone of resin tags within the dentin substrate when used in the total-etching mode, ensuring greater adhesion than in the self-etching mode.…”

BackgroundThe literature is scanty regarding the effect of radiation therapy (RT) on the mechanical properties of immature permanent teeth.AimTo evaluate the effect of RT on the fracture resistance of simulated immature teeth submitted to different types of root reinforcement.DesignSixty‐four human teeth simulating the Cvek stage 3 of root development were distributed into eight groups (n = 8), according to exposure or not to RT (70 Gy) and the root reinforcement method: Group NR (control)—no reinforcement/no RT; Group NR + RT (control)—no reinforcement/RT; Group PO—tricalcium silicate‐based cement (TS) apical plug/canal obturation/no RT; Group PO + RT—TS apical plug/canal obturation/RT; Group TS—canal filling with TS/no RT; Group TS + RT—canal filling with TS/RT; Group FP—TS apical plug/fibreglass post/no RT; and Group FP + RT—TS apical plug/fibreglass post/RT. Fracture resistance was determined using a universal testing machine (0.5 mm/min).ResultsIn the intergroup comparison, nonirradiated teeth had higher fracture resistance (p < .05). Groups FP and FP + RT had higher fracture resistance (p < .001).ConclusionRadiotherapy affected the fracture resistance of simulated immature teeth. Reinforcement with fibreglass posts increased the fracture resistance, regardless of the radiation.

ObjectivesTo investigate the effect of cumulative doses of radiation on the pushout bond strength (BS) of a universal resin cement used in the self‐etch (SE) and self‐adhesive (SA) modes to the intraradicular dentin.Materials and MethodsForty‐eight human teeth were distributed into three groups (n = 16) according to the radiation therapy dose (RT): NoRT (no‐radiotherapy), 70RT (70 Gy), and 70 + 70RT (70 Gy + 70 Gy). The teeth were redistributed into two subgroups (n = 8), according to the adhesive mode: SE (NoRT‐SE, 70RT‐SE, and 70 + 70RT‐SE) and SA (NoRT‐SA, 70RT‐SA, and 70 + 70RT‐SA). Data were statistically compared after BS test (ANOVA, Tukey's post hoc test, and Fisher's exact test).ResultsIn the SA mode, BS was significantly higher in nonirradiated teeth compared with 70RT and 70 + 70RT (p < 0.0001). There were no significant differences between SE and SA modes in nonirradiated teeth (p = 0.14). In the 70RT group, SE mode increased BS compared with SA mode (p < 0.0001). Most specimens had adhesive and mixed failures in SA and SE modes, respectively.ConclusionsThe universal resin cement in the SE mode had greater BS to the irradiated dentin. When teeth were re‐irradiated, the universal resin cement had similar performance in terms of BS, regardless of the adhesive approach.Clinical SignificanceThere is no research establishing a correlation between radiotherapy and its impact on the BS of a universal resin cement used in SE and SA modes to intraradicular dentin.
