Cephalometric analysis of the relationship between temporomandibular joint disc displacement and occlusal plane.

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 temporomandibular joint (TMJ) is biomechanically complex, with disc displacement (DD) causing dysfunction and pain, while the occlusal plane (OP) influences TMJ mechanics. This study investigates the correlation between disc displacement and OP to inform DD.
methodsThis study included adult patients with temporomandibular disorder complaints. Participants were divided into three groups based on magnetic resonance imaging (MRI): normal position (N), disc displacement with reduction (DDwR), and disc displacement without reduction (DDwoR). The sagittal and vertical relationships, mandible morphology, dental relationships, and occlusal related index were evaluated using cephalometric measurements. A regression equation was then established after adjusting confounding factors.
resultsANOVA test showed that statistical differences (p < 0.05) could be seen in SNB, ANB, FMA angle, SN-MP, S-Go, Ar-Go and U1-SN among the three groups. As for the occlusal plane related index, FH-OP, FH-POP, MP-OP, FH-U6, FH-L6 had statistical differences with the position of articular disc. The exploration on the occlusal plane related index in sagittal skeletal pattern categorial showed that skeletal pattern did not affect the relationship between the articular disc and the occlusion plane. Additionally, binary logistic regression analysis indicated that the likelihood of DDwoR increases with a one-degree increment in FH-POP and decreases with a one-degree decrement in both FH-U6 and FH-L6.
conclusionsCompared with the other two groups, the DDwoR group possessed different craniofacial features. Additionally, the posterior occlusal plane, not anterior or the complete occlusal plane, and axis inclination of first molar is related to DD. In short, there exists an association between articular disc and OP. However, the causal relationship cannot be confirmed, further investigation is still needed between these factors.
