Effect of different ceramic materials and dentin sealing on occlusal veneers bond strength and fracture resistance.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
backgroundThe effect of immediate dentin sealing (IDS) or delayed dentin sealing (DDS) on bond strength of different ceramic occlusal veneer restorations, was not examined yet, but the digital quantification of surface area of preparations helped in the calculation of the actual bond strength of these restorations, besides that, dentin sealing could influence the fracture resistance values of different ceramic occlusal veneer restorations. This study aimed to examine the effect of different dentin sealing strategies and different restorative materials on the debonding forces, bond strength and fracture resistance of occlusal veneer restorations. MATERIALS AND
methodsHuman mandibular molars (N = 64/test) were prepared for occlusal veneer restorations fabricated from Lithium disilicate ceramic (LS) (control group), Zirconia-reinforced lithium Silicate ceramic (ZLS), High translucent zirconia ceramic (HZ), and Resin nano ceramic (LU) (n = 16). Each material was subdivided according to IDS or DDS application, (n = 8). Bond strength testing and fracture resistance values were measured using universal testing machine. Two-way ANOVA was performed to investigate the effects of the two variables, dentin sealing and material selection, and their interaction (α = 0.05), followed by One-way ANOVA and post hoc or Student t-test for further determination of significance.
resultsFor debonding forces and bond strength testing there were significant differences regarding different materials and dentin sealing strategies, while for fracture resistance, the material selection had a significant effect on it with no significant effects of dentin sealing strategies. The interaction between materials and dentin sealing showed no significant differences concerning all tests. For debonding forces and bond strength there was a higher result related to IDS application than DDS (p < 0.001*), and there was a significant effect of material selection on them (LS > ZLS > HZ > LU), (p = 0.001
conclusionImmediate dentin sealing increased the required debonding forces of occlusal veneers made of different materials and their bond strength without significant effect on their fracture resistance, however this improvement was found to be material dependant. All the used materials can withstand lateral and occlusal forces higher than the values recommended for restoring posterior teeth.
