This study aimed to estimate the prevalence of PD among 9th-grade teachers in the northern West Bank and examine its association with key behavioral and socioeconomic factors. Methods: A cross-sectional study was conducted among 920 teachers selected through proportional stratified random sampling from governmental and private schools. Periodontal health was assessed using the WHO Community Periodontal Index for Treatment Needs (CPITN), and oral hygiene status was measured with the Simplified Oral Hygiene Index (S-OHI). A structured questionnaire was administered to collect data on socioeconomic status, oral hygiene practices, dietary habits, and smoking behaviours. Data was analysed using descriptive statistics, bivariate and multivariate logistic regression. Results: Only 11.8% of participants exhibited completely healthy gingiva, with the mean condition ranging between calculus and shallow pockets. Oral hygiene practices were the strongest predictors of periodontal outcomes: frequent tooth brushing (Adjusted Odds Ratio: AOR = 0.015), morning brushing (AOR = 0.015), and regular toothbrush replacement (AOR = 2.514) were protective. Higher red meat intake was negatively associated with periodontal health (AOR = 0.032), while frequent nut consumption was protective (AOR = 0.227). The number of cigarettes smoked per week was positively associated with PD (AOR = 1.085). Conclusions: PD is highly prevalent among Palestinian adults, with significant behavioural and lifestyle-related determinants. Targeted oral health interventions are urgently needed to improve adults\u2019 oral health.<\/jats:p>","DOI":"10.3390\/dj14010053","type":"journal-article","created":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T10:13:51Z","timestamp":1768299231000},"page":"53","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Prevalence and Socio-Behavioural Determinants of Periodontal Disease Among Adults in the Northern West Bank: A Cross-Sectional Study"],"prefix":"10.3390","volume":"14","author":[{"given":"Sura","family":"Al-Hassan","sequence":"first","affiliation":[{"name":"Faculty of Public Health, Al-Quds University, Jerusalem 51000, Palestine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mazen","family":"Kazlak","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Health Sciences, An-Najah National University, Nablus 00970, Palestine"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2077-3257","authenticated-orcid":false,"given":"Elham","family":"Kateeb","sequence":"additional","affiliation":[{"name":"Oral Health Research and Promotion Unit, Faculty of Dentistry, Al-Quds University, Jerusalem 51000, Palestine"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,1,13]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"459","DOI":"10.1038\/sj.bdj.2014.908","article-title":"The prevalence of periodontal disease in a Romano-British population c. 200\u2013400 AD","volume":"217","author":"Molleson","year":"2014","journal-title":"Br.
