Impact of Various Sleeve Materials on Temperature Variations During Guided Endodontic Access Cavity Preparation Utilizing Finite-Element Analysis.
Article in Clinical and experimental dental research, 2026. 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
purposeGuided endodontics allows precise access in challenging cases such as calcified canals; however, drilling can generate temperature increases that risk damaging periradicular tissues. This study aimed to evaluate the influence of different sleeve materials-zirconia, cobalt-chromium (CoCr), and titanium-on temperature changes during guided endodontic access using finite-element analysis (FEA). MATERIALS AND
methodsHigh-resolution three-dimensional (3D) models of a human central incisor and titanium sleeve were developed using micro-computed tomography (micro-CT), 3D Slicer, Meshmixer, and SolidWorks. FEA simulations were conducted in Abaqus under a 2° deviation and 700 rpm drilling, with thermal properties based on literature. Experimental validation employed thermocouples to determine the temperature changes under identical conditions.
resultsResults showed that zirconia sleeves produced the lowest temperature elevation (< 10°C) with localized concentration, while CoCr and titanium allowed more even heat dissipation.
conclusionZirconia is an effective insulator due to its thermal conductivity properties. CoCr has emerged as a promising alternative to titanium, offering more favorable thermal and mechanical characteristics.
