1 · What the graph read from 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.

2 · The registry

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

objectiveA 3D finite element model of the mandibular second molar and its periodontal ligament (PDL) was designed to study the impact of different occlusal contact points on tooth mobility and to identify more stable occlusal contact patterns for precise clinical adjustments and prosthesis design.

methodsA 300 N static load was applied vertically to the tooth’s occlusal surface. Two contact types were evaluated: cusp tip-fossa contact (Model 1) and cusp-fossa tripod contact (Model 2). The study focused on tooth mobility in 94 occlusal contact patterns.

resultsIncreased contact points reduced overall tooth displacement. Teeth showed greater movement with only mesial contact compared to distal contact. Some occlusal contact patterns proved to be more stable than those in Models 1 and 2.

conclusionsA uniform distribution of multiple occlusal contact points improved teeth stability. There were additional stable occlusal contact patterns in the mandibular second molars.
