Effect of periodontal disease on bite force and the temporomandibular joint disorders: a cross-sectional study.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundAlveolar bone loss (ABL), tooth mobility, tooth displacement, and tooth loss due to periodontitis can lead to temporomandibular joint (TMJ) problems and reduced masticatory function. While previous studies have examined the associations between periodontal disease, bite force (BF), and temporomandibular disorders (TMDs) separately, the combined impact of periodontal breakdown on both masticatory function and TMJ involvement has not been clearly established. Therefore, this study aimed to determine the relationship between ABL and BF and to evaluate the incidence and characteristics of TMDs in patients with periodontitis.
methodsThis cross-sectional study enrolled 50 patients with stage III generalized periodontitis and 50 periodontally healthy participants. Sociodemographic data and clinical periodontal parameters were collected. BF was measured and compared between periodontitis and periodontally healthy groups. The TMJ was assessed using an interview-based questionnaire and clinical examination.
resultsTMD pre-diagnostic classifications were not significantly different between the groups (p = 0.772, p > 0.05). Complaints of pain in the jaw upon waking (p = 0.044), clicking/locking of the jaw (p = 0.020), and daytime bruxism (p = 0.042) were significantly fewer in the periodontitis group than in the healthy group (p < 0.05). Meanwhile, TMJ-related symptoms were not significantly different between the periodontitis and healthy groups. However, BF was significantly lower in the periodontitis group than in the healthy group (p < 0.001).
conclusionsBF is decreased in patients with periodontitis. Periodontal treatment should be completed, and missing teeth, if any, should be rehabilitated to enable efficient masticatory function in these patients.
