Background: There are limited data about the epidemiology and risk factors/indicators of gingivitis, aggressive\r\nperiodontitis (AgP) and chronic periodontitis (CP) in Jordan. The aim of this study was to assess the prevalence and\r\nrisk indicators of gingivitis, AgP and CP.\r\nMethods: A sample of 595 subjects was randomly selected from subjects escorting out-patients attending a\r\nMedical Center, a Dental Teaching Hospital, and 2 private dental clinics. The socio-demographic variables, oral\r\nhygiene habits, income, smoking and Body Mass Index (BMI) were recorded. Full mouth periodontal examination\r\nwas performed, and radiographs were taken for sites with probing depth > 3 mm.\r\nResults: About 76% had gingivitis, 2.2% had AgP and 5.5% had CP. Periodontitis was more frequent among males\r\nthan females with a M: F ratio of 1.6:1 and the prevalence increased with age. Subjects who reported not using a\r\ntooth brush, smokers and subjects with BMI > 30 kg/m2 had significantly higher prevalence of periodontitis. The\r\nrisk for periodontitis was greater among subjects who reported positive family history and subjects with = 12 years\r\nof education.\r\nConclusions: This is the first study to report on the prevalence of gingivitis, CP and AgP in North Jordanian. Age,\r\nlow education, low frequency of tooth brushing and family history were significantly associated with increased risk\r\nof periodontitis.
