Association Between Fagerström Nicotine Dependence Score, Periodontal Disease Awareness, and Clinical Periodontal Parameters in Individuals With Gingivitis or Periodontitis: A Cross-Sectional Study

Cigarette smoking is a well-established risk factor for periodontal disease and has been associated with increased periodontal destruction and impaired healing responses. However, smoking may also influence the perception and recognition of periodontal disease symptoms. Previous periodontal research has primarily evaluated smoking exposure using quantitative measures such as daily cigarette consumption and duration of smoking. These measures may not fully capture the behavioral and psychological aspects of nicotine addiction.

Nicotine dependence represents a behavioral component of smoking behavior that may affect how individuals perceive symptoms and respond to disease-related changes in their oral health. The Fagerström Test for Nicotine Dependence (FTND) is a validated instrument widely used to quantify nicotine addiction levels. Despite its extensive use in smoking research, the relationship between nicotine dependence and periodontal disease awareness has received limited attention in periodontal literature.

The present study is designed as a cross-sectional observational investigation conducted among individuals diagnosed with gingivitis or periodontitis. Participants will be recruited from patients attending a periodontal clinic. After obtaining informed consent, participants will complete the FTND questionnaire and a brief questionnaire assessing periodontal disease awareness.

A comprehensive periodontal examination will be performed by an experienced periodontist. Clinical parameters including plaque index, bleeding on probing (BOP), maximum probing depth (PD), and maximum clinical attachment loss (CAL) will be recorded using standardized periodontal probes.

The primary aim of the study is to evaluate whether nicotine dependence level is associated with periodontal disease awareness. Secondary analyses will examine associations between nicotine dependence and clinical periodontal parameters, including PD, CAL, and BOP, in order to explore potential pathways linking nicotine dependence with periodontal disease perception.
