Association of periodontal status with patient-reported outcomes: oral health-related quality of life and dental anxiety in a cross-sectional study.
Observational study in BMC public 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
objectivesThis study aimed to evaluate oral health-related quality of life (OHRQoL) and dental hygiene fear across periodontal status groups, including periodontally healthy individuals and patients classified according to different stages of periodontitis, and to examine their associations with sociodemographic, behavioral, and clinical periodontal parameters. MATERIALS AND
methodsThis single-center, cross-sectional observational study included 999 participants recruited from the Periodontology Clinic of Zonguldak Bülent Ecevit University Faculty of Dentistry between December 2018 and December 2019. Participants were classified into three groups according to periodontal status: periodontally healthy individuals (n = 399), those with combined Stage I-II periodontitis (n = 300), and those with combined Stage III-IV periodontitis (n = 300). Sociodemographic characteristics, oral hygiene habits, dental attendance patterns, and smoking status were recorded using structured questionnaires. Periodontal parameters, including the plaque index, gingival index, probing depth, clinical attachment level, and tooth loss, were assessed clinically. Oral health-related quality of life and dental hygiene fear were assessed using the Oral Health Impact Profile-14 (OHIP-14) and the Dental Hygiene Fear Scale (DHFS), respectively.
resultsThe OHIP-14 total scores increased progressively with periodontal disease severity, with the highest scores observed in the combined Stage III-IV periodontitis group. Significant intergroup differences were found for most of the OHIP-14 domains, except for psychological discomfort. The DHFS scores also differed significantly among the groups and were highest in patients with combined Stage III-IV periodontitis. The OHIP-14 scores were significantly associated with marital status, education level, smoking status, tooth brushing frequency, dental visit frequency, and time since the last dental visit. DHFS scores were higher in females, married individuals, and those with lower educational levels. The OHIP-14 showed positive correlations with DHFS and clinical periodontal parameters, including plaque index, gingival index, probing depth, clinical attachment level, tooth loss, and age.
conclusionsPeriodontitis severity was associated with a poorer oral health-related quality of life and higher dental hygiene fear. These findings highlight the importance of incorporating patient-reported outcomes into periodontal assessment and care. Nevertheless, the possibility of residual confounding from unmeasured socioeconomic and systemic factors cannot be excluded.
