Supportive periodontal therapy: individual patients' perception of various professional interventions.
Observational study 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
backgroundEvidence on psychophysiological responses such as heart rate (HR) and electrodermal response (EDR) during long-term supportive periodontal therapy (SPT) is limited. This observational cross-sectional pilot study aimed to explore associations between patient-related factors and physiological stress markers during routine SPT visits, focusing on adherence-related variables.
methodsA sample of n = 75 patients was examined in a questionnaire-based, cross-sectional survey, indicating sufficient adherence to SPT of ≥ 2 years (a maximum deviation ± 6 months between SPT intervals) at a specialized department for periodontology. At the preliminary last SPT visit, in addition to dental parameters, we assessed socio-demographic, treatment-related (critical attitudes/complaints), psychological variables-such as dental fear, oral health-related quality of life, dental anticipatory trauma symptoms, childhood traumata, depression, and personality functioning-and vital parameters such as HR and EDR. The primary endpoint was the difference in HR and EDR across predefined procedural clusters reflecting varying invasiveness (three clusters: non-invasive (n-iC), minimally invasive (m-iC), and invasive (iC). Analyses were performed using non-parametric tests and exploratory correlation analyses.
resultsThe mean (standard deviation) of HR differed significantly across intervention clusters (n-iC/m-iC/iC: 73.06[11.96]/67.66[9.60]/69.46[10.00] bpm; p ≤ 0.001), while EDR revealed no significant differences (n-iC/m-iC/iC: 69.64[156.65]/61.72[172.20]/75.10[154.07] µS; p ≥ 0.075). EDR negatively correlated with the number of teeth m-iC-interventions (r = -0.423; p = 0.003). Moreover, EDR and HR were significantly related to certain variables such as long-term medication and number of general diseases (p < 0.001). Significant correlations included a positive association between Oral Health Impact Profile scores and dental anxiety (r = 0.233; p = 0.040) and a negative correlation with the total number of teeth (r = -0.378; p < 0.001).
conclusionSocio-demographic and treatment-related factors were intertwined with patient and dental parameters in SPT and appeared to influence adherence. HR varied across clusters, but no clear link between vital signs and psychological stress could be established.
