Background: Data on the periodontal status of the adult population in the Arab world are scarce. The aim of this pilot study was to assess the prevalence, extent and severity of periodontal diseases in an adult group from Oman. Methods: This is a cross-sectional study of 319 teachers who were randomly sampled from the Muscat region schools' list of teachers in Oman. Dental caries, tooth loss, and periodontal attachment loss were recorded for each of the participants. A questionnaire collected data on participants' socio-demographic characteristics, dental care characteristics, self-rated periodontal status and self-rated wellbeing. Results: 99% of participants had at least one site with probing depth (PD) or clinical attachment loss (CAL) of 3+mm. More than one-third (36%) of participants had at least one site with 5+mm CAL, and 12% had at least one site with 6+mm CAL. For PD, the prevalence estimates were 26% and 8%, respectively, and a gradient by age group was evident across the different thresholds. Where the extent of disease was concerned, 17.6% of sites had 3+mm PD, and 21% of sites had 3+mm CAL. Conclusion: The prevalence, extent and severity of periodontitis were higher than estimates reported from industrialised countries such as Australia, New Zealand and the USA. This is of concern, especially when considering the relatively young age of the population under study. Because of this high prevalence, investigation of periodontitis in a national sample of Omanis is desirable to confirm the findings of this study.
