Oral health status and associated lifestyle behaviors in a sample of Iranian adults: an exploratory household survey

Abstract

Abstract Background Poor oral hygiene can lead to serious diseases, such as periodontitis, tooth decay, pain and discomfort in teeth or gums, infections, and loss of teeth. In Iran, adults aged 50 y and older are a high-risk group for oral health problems, and this age group will grow in the coming decades. Despite increasing attention on healthy aging, there is relatively less emphasis on oral hygiene and health-related problems. The present study investigated the oral health status of Iranian adults using the oral health self-assessment questionnaire (OHQ) developed by the World Health Organization (WHO). Methods A population-based household survey of a sample of adults aged 18–65 y was conducted. In this study, the participants were recruited between May and October 2016 in Tabriz, Iran, and the study population was sampled using a multi-stage cluster sampling design. The WHO’s OHQ for adults was used for measuring oral health status and oral hygiene behavior. Results In total, 2310 respondents completed the survey. The mean age (SD) of the participants was 41.6(23.4) y. Males accounted for 48.8% of the participants. Of the 2310 respondents,187 (8.1%) individuals were edentulous, 152(20.7%) of whom were aged 51–65 y. Furthermore, 72.3% of those aged 51–65 y were dentate, and 50% of adults aged 51–65 y said they had 20 or more teeth. About one-third of the participants reported that they did not brush their teeth daily (23% of those aged 18–35 y,35.9% of those aged 36–50 y, and 44.6% for those aged 51–65 y). In the sample, 39.4% of individuals aged 18–35 y,34.1% of individuals aged 36–50 y, and 26.6% of individuals aged 51–65 y had visited a dentist less than 6 month ago. One-third of the participants consumed sweets and sugary drinks daily. Conclusions Although the majority of Iranian adults considered their oral health status good, only a small percentage of the sample visited their dentist regularly. Furthermore, visits to the dentist declined in accordance with increasing age, a time when the incidence of oral health problems may increase. Poor oral health may increase the risk of adverse health outcomes, particularly among the aging population.
