Effect of crosslinking/antioxidant agents as final irrigant on the fracture resistance of endodontically treated root after radiotherapy.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimTo investigate the effects of Epigallocatechin gallate (EGCG) and curcumin, as a final irrigant on the fracture resistance of irradiated root that obturated with an epoxy resin sealer. METHODOLOGY: Eighty mandibular premolars were randomly divided into non-irradiated (NIR) and irradiated (IR) groups. The teeth were irradiated at 2 Gy per fraction, 5 times a week for a total dose of 60 Gy over 6 weeks. All specimens were decoronated, remaining 13±1 mm root length. Two groups were subdivided into four groups (n = 10): 1) non-instrumented; the intact root served as control. The other roots were instrumented with a pro-taper NiTi rotary system. The final irrigation used was 17% EDTA, followed by three irrigation solution groups; 2) 2.5% NaOCl, 3) 0.02% EGCG, and 4) 0.1% curcumin. Root canals were filled with gutta-percha and AH plus. All specimens were embedded in self-curing acrylic resin and loaded vertically at 1 mm/min until fracture occurred. Also, sealer penetration was assessed by confocal laser scanning microscopy (CLSM). The data were evaluated statistically using two-way ANOVA and Tukey test (α = 0.05).
resultsIn irradiated roots, fracture resistance of EGCG and curcumin groups did not differ from non-instrumented roots, but they were higher than the NaOCl group (P = 0.006). However, NaOCl, EGCG, and curcumin in irradiated roots had comparable strength that was higher than in the non-instrumented group (p<0.001). Difference between irradiated and non-irradiated roots was observed only for NaOCl and non-instrumented groups (P≤0.004). In irradiated roots, a higher sealer penetration was observed in EGCG and curcumin groups compared to NaOCl.
conclusionEGCG and curcumin could be promising final irrigants to reverse the adverse effect of radiotherapy on the strength of irradiated roots obturated with AH Plus sealer.
