The aim of the survey was to estimate the prevalence of chronic periodontitis among Saudi nationals in Aljouf Province, Kingdom of Saudi Arabia. 310 subjects were selected by stratified cluster sampling technique. They were examined in preselected areas of Aljouf region by using community periodontal index of treatment need. The impact of known risk factors for periodontal disease, e.g., oral hygiene habits, age and smoking. 53% of the subjects and 15.8% of the sextants. Shallow pockets were observed in 39.4% of the subjects and 38.4% of the sextants. Calculus was found to be present in 9.8% of the subjects and 48.8 % of the sextants. Calculus was maximum (53%) in group I (30-40 years) and minimum (21%) in Group IV (60 years and above). Periodontal disease was found to be highly prevalent in the study population (90%) and the periodontal treatment needs increased with advancing age.
