Are dental practitioners prepared to recognize stomatognathic movement disorders? A cross-sectional study of knowledge, diagnostic confidence, and educational needs.

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
backgroundStomatognathic movement disorders (SMDs) are uncommon but clinically significant neurological conditions that frequently present with orofacial manifestations. Because affected patients may initially seek care from dental practitioners, limited awareness of these disorders could contribute to diagnostic confusion with temporomandibular disorders (TMDs) and may have implications for timely referral and appropriate patient management. This study evaluated dental practitioners' knowledge, diagnostic confidence, and educational preparedness regarding SMDs.
methodsA cross-sectional survey was conducted among dental practitioners using a validated self-administered online questionnaire. Knowledge scores were calculated out of 25 points and expressed as percentages. Comparative analyses were performed across educational levels using one-way ANOVA, chi-square tests, and multivariable logistic regression.
resultsA total of 156 dental practitioners participated. Mean knowledge scores differed significantly across academic level (Bachelor: 44.05%, Master: 48.95%, Doctorate: 63.71%; p < 0.001). Doctoral-level education independently predicted adequate knowledge (OR = 8.54, 95% CI: 2.09-34.97; p = 0.003), whereas master's-level showed no significant effect. Knowledge gaps were observed in several domains, particularly in distinguishing SMDs from TMDs and in the management of oromandibular dystonia. Only a minority of participants correctly recognized that temporomandibular joint radiographs are not routinely required prior to treatment. Self-reported clinical confidence was generally low, with only 1.1% of general dentists reporting the ability to independently manage suspected SMD cases. Nevertheless, 94.9% of participants supported integrating SMD-related content into dental curricula.
conclusionThe surveyed dental practitioners demonstrated important knowledge gaps regarding SMDs. These findings highlight opportunities to strengthen undergraduate and continuing dental education in the recognition, differentiation from TMDs, and appropriate referral of patients with suspected SMDs.
