Effects of the Presence of Adjacent Tooth and Material Type on the Marginal and Internal Adaptation of Endocrowns Fabricated by the Digital Impression Technique.
Article in Clinical and experimental dental research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
purposeTo assess the effects of the presence of adjacent tooth and material type on the marginal and internal adaptation of endocrowns fabricated by the digital impression technique. MATERIAL AND
methodsAn endodontically treated molar tooth was used for the fabrication of endocrowns in this in vitro study. Five groups of specimens (n = 17) were evaluated based on the material type and presence of adjacent tooth: three groups of monolithic zirconia (Zir), lithium disilicate (LDS), and zirconia-reinforced lithium silicate (ZLS) in the presence of adjacent teeth, and two groups of zirconia endocrowns, one in the absence of an adjacent anterior tooth (second premolar; Zir-no ant.) and one in the absence of a posterior adjacent tooth (second molar; Zir-no post.). Marginal and internal adaptation of endocrowns was evaluated by the silicone replica technique. Data were analyzed by ANOVA with Tukey test for pairwise comparisons and generalized estimating equation with Bonferroni correction for pairwise comparisons (α = 0.05).
resultsThe largest marginal gap was found in the ZLS, followed by the LDS and Zir groups (p < 0.05). The Zir group showed significantly higher internal adaptation than the ZLS group (p < 0.05); LDS had no significant difference with the ZLS and Zir groups (p > 0.05). The Zir group showed larger marginal and internal gaps than the Zir-no ant. and Zir-no post. groups (p < 0.05); the latter two groups had no significant difference (p > 0.05). All groups showed the largest gap at the pulpal and the smallest gap at the marginal and cervical areas (p < 0.05).
conclusionZirconia endocrowns showed the highest marginal and internal adaptation. Digital impression technique in absence of anterior or posterior adjacent tooth would result in higher marginal and internal adaptation of endocrowns.
