Bridging the perception-practice gap: a mixed-methods study on interprofessional collaboration for diabetes and periodontitis management.
Article in BMC oral health, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundDiabetes and periodontitis have a bidirectional association, yet interprofessional collaboration (IPC) for their management remains inconsistent in clinical practice. Notably, national and international guidelines often omit oral health assessment from routine diabetes management. This study aims to assess primary care professionals’ perceptions of this association and their related management practices, and to explore the underlying barriers to low bidirectional screening and referral rates.
methodsA sequential explanatory mixed methods design was used. Community medical practitioners, community nurses, and dentists were recruited via stratified sampling from relevant healthcare institutions. First, an online quantitative questionnaire assessed their knowledge of the diabetes-periodontitis association, clinical behaviors, and referral practices. Subsequently, semi-structured qualitative interviews were conducted with a subset of participants to explore the reasons for the perception-practice gap, based on the quantitative findings.
resultsA total of 319 participants completed the questionnaire, with 118 of them also taking part in semi-structured interviews. Over 90% of participants recognized the bidirectional association between diabetes and periodontitis, yet obvious gaps existed in clinical practice. Professional groups also differed in perceptions, particularly of screening responsibilities. Thematic analysis of interviews identified three key issues undermining IPC.
conclusionAlthough primary care and dental professionals widely acknowledge the bidirectional association between diabetes and periodontitis and show willingness to collaborate interprofessionally, a notable perception-practice gap remains in their collaborative management. To address this, targeted interprofessional training, clear referral protocols, and strengthened policy support are recommended to enhance the effectiveness of IPC in primary care.
