Brief summary

This observational cross-sectional study aimed to investigate the association between oral health literacy (OHL) and periodontal status among adult individuals attending Biruni University Faculty of Dentistry, Istanbul, Türkiye. A total of 108 adults were evaluated using the Turkish version of the Rapid Estimate of Adult Literacy in Dentistry (TREALD-30) to assess OHL levels. Periodontal examination included probing depth, clinical attachment level, bleeding on probing, and plaque index. The study sought to determine whether lower OHL levels are associated with poorer periodontal health and to highlight the importance of improving health literacy in oral disease prevention and management.

Detailed description

This cross-sectional observational study was conducted at Biruni University Faculty of Dentistry, Istanbul, Türkiye, to evaluate the relationship between oral health literacy (OHL) and periodontal status among adult individuals. A total of 108 systemically healthy adults aged 18 years or older were included. Individuals with fewer than 20 teeth, history of periodontal treatment in the past 6 months, or systemic diseases affecting periodontal health were excluded. OHL was assessed using the validated Turkish version of the Rapid Estimate of Adult Literacy in Dentistry (TREALD-30). Periodontal examination was performed by a calibrated periodontist and included full-mouth probing depth (PD), clinical attachment level (CAL), bleeding on probing (BOP), and plaque index (PI). Periodontitis was defined according to the 2018 World Workshop classification system. The primary objective was to determine whether limited OHL is associated with worse periodontal parameters. Secondary objectives included evaluating the relationship between OHL and sociodemographic variables such as age, education, and smoking habits. Statistical analyses were performed using regression models to identify independent predictors of periodontal disease. The findings of this study aim to emphasize the role of oral health literacy as a potential social determinant of periodontal health and to guide the development of literacy-based preventive strategies in dental public health.

Interventions

OTHERObservational Assessment

No intervention was performed. Participants underwent a non-invasive periodontal examination and completed the Turkish version of the Rapid Estimate of Adult Literacy in Dentistry (TREALD-30) questionnaire to assess oral health literacy.

Design outcomes

Primary

MeasureTime frameDescription
Association between oral health literacy and periodontal statusBaseline (single examination at enrollment)The primary outcome is the relationship between oral health literacy, measured by the Turkish version of the Rapid Estimate of Adult Literacy in Dentistry (TREALD-30), and periodontal status based on the 2018 World Workshop classification. Periodontal parameters include probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP).

Secondary

MeasureTime frameDescription
Association between oral health literacy and demographic factorsSingle time point (baseline examination)To assess the association between oral health literacy levels and demographic characteristics such as age, gender, and educational attainment among adult participants.
Relationship between oral health literacy and smoking statusSingle time point (baseline examination)To determine whether smoking habits are associated with lower oral health literacy scores and poorer periodontal parameters.
Association between oral health literacy and oral hygiene behaviorsSingle time point (baseline examination)To evaluate the relationship between oral health literacy (measured by the TREALD-30) and self-reported oral hygiene practices, including toothbrushing frequency, use of interdental cleaning aids, and frequency of dental visits.
