Evaluation of Void Volume and Blood Contamination-Induced Changes in Surface Microhardness of Calcium Silicate-Based Cement, Sealer, and Their Combination (Lid Technique) in Retrograde Filling.
Article in European endodontic journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectiveThis study aimed to compare the effect of blood contamination on the surface microhardness and void volume of a calcium silicate-based cement, sealer, and a combination of the two (Lid technique) when used for retrograde filling.
methodsThirty mesial roots of extracted human mandibular molars were divided into three groups: iRoot BP Plus (cement), iRoot SP (sealer), and a combination of the two (Lid technique). The root ends of the teeth were resected and prepared, and the roots were filled. The void volumes were evaluated using micro-computed tomography. Sixty clear resin replicas were created to assess the microhardness after exposure to phosphate-buffered saline and blood; measurements were obtained after 4 and 30 days.
resultsAll groups exhibited similar void volumes. The groups retrofilled with iRoot BP Plus and the Lid technique had higher microhardness values than the iRoot SP group. The iRoot SP group displayed similar microhardness values after exposure to PBS and blood. Blood contamination reduced the microhardness values in the iRoot BP Plus and Lid technique groups; however, no significant differences were observed between the measurement times (P > 0.05).
conclusionIn multi-canal roots, the lid approach is as effective as traditional root-end filling. Blood contamination reduced microhardness emphasizing the significance of handling materials with care during endodontic microsurgery. (EEJ-2024-10-159).
