Objective: To investigate the oral health status of 35- to 44-year-old Iranians in relation to gender, place of residence and education. Subjects and Methods: In 2002, data (n = 8,301) were collected as part of a national survey using WHO criteria for sampling and clinical diagnoses across 28 provinces by 33 calibrated examiners who performed examinations under a dental light with a WHO probe. The study sample was 8,301; male: 3,625 and female: 4,676; urban: 4,854 and rural: 3,447. Oral health status was assessed by number of decayed (DT), filled (FT) and missing (MT) teeth and by DMFT and need for periodontal treatment [community periodontal index for treatment needs (CPITN)] indices. Gender, age, place of residence and level of education served as socio-demographic information. Estimates were adjusted for the 35- to 44-year-old provincial population. ANOVA, χ2 test and logistic regression analysis with odds ratios (OR) and their 95% confidence intervals (CI) were the methods of statistical evaluation used. Results: The mean number of teeth was 21.5 ± 6.2, with DMFT: 11.0 ± 6.4, DT: 2.6 ± 2.7, and FT: 1.8 ± 3.2. DT existed in 6,080 (73%) of the subjects and FT in 3,209 (41%). The mean number of FT was greater (p < 0.001) among urban residents, women and those with a higher level of education. Only 1% had a CPITN of 0; 6% exhibited bleeding, 40% had calculus, 43% shallow and 10% deep pockets. Illiterate subjects were more likely to have DT (OR = 1.6, 95% CI = 1.4–1.8) and calculus or periodontal pockets (OR = 6.3, 95% CI = 5.1–7.8). Conclusion: The findings indicate an impaired oral health status in Iranian adults, particularly those of low social status and educational level.
This study aimed to investigate the frequency of tooth loss and the magnitude of prosthodontic rehabilitation based on socio-demographic information among 35- to 44-year-old Iranians. Data (n = 8240) were collected by 33 examiners as part of a national survey using WHO criteria for sampling and clinical diagnosis. Gender, age, place of residence and level of education served as socio-demographic information. The number of teeth, functional dentition (subjects with 20 or more teeth) and prosthodontic rehabilitation were used as clinical variables. The chi-square test and logistic regression analysis were the methods of statistical evaluation. Of all subjects, 3% were edentulous. Of dentate subjects, 3% had 1-9 teeth, 21% had 10-19 teeth, 37% had 20-24 teeth and 39% had 25-28 teeth. In total, 76% of dentate subjects enjoyed a functional dentition. Among dentate subjects, 11% of the men and 16% of the women had prosthodontic rehabilitation with higher figures (P < 0.001) among women, older subjects and urban residents. Having a functional dentition was more likely among those with higher levels of education [odds ratios (OR) = 1.8, 95% confidence intervals (CI) = 1.6-2.1]. Women (OR = 2.4, 95% CI = 1.8-3.0) and urban residents (OR = 2.4, 95% CI = 1.8-3.3) were the most likely groups to have prosthodontic rehabilitation. Having prosthodontic rehabilitation was more likely among those lacking a functional dentition (OR = 6.0, 95% CI = 4.8-7.6). The greatest unmet treatment needs were found among those without a functional dentition. Functional dentition should be set as a primary oral health goal among working-age adults.
Objective: To investigate the oral health status of 18-year-old Iranians in relation to their gender, place of residence and level of education. Subjects and Methods: Thirty-three calibrated examiners in 2002 collected data as part of a national survey, according to World Health Organization criteria for sampling and clinical diagnoses, across 28 provinces. The study sample was 4,448; male: 2,021 and female: 2,427 made up of urban: 2,564 and rural: 1,884. Oral health status was assessed in terms of number of teeth, decayed teeth (DT), filled teeth (FT), decayed, missing or filled teeth (DMFT), community periodontal index and plaque index. Results: The mean number of teeth was 27.4, with DMFT: 4.3, DT: 3.0 and FT: 0.7. The mean number of sound teeth was higher (p < 0.01) in men (24.1 vs. 23.3 in women), FT in urban residents (1.0 vs. 0.2 in rural residents) and DT in women (3.3 vs. 2.8 in men). Three of 4 subjects were in need of restorative treatments. All subjects had dental plaque; 387 (8%) healthy gingiva; 1,016 (23%) exhibited bleeding; 2,025 (48%) calculus and 1,020 (21%) deepened pockets. Men’s periodontal status was worse than women’s (p < 0.002). Low level of education was associated with having 27 or fewer teeth (OR = 1.7), calculus (OR = 1.5) or deep periodontal pockets (OR = 2.7). Conclusion: A majority of 18-year-old Iranians seem to enjoy a full dentition. High prevalence of dental plaque, calculus, periodontal pockets and untreated dental cariesespecially among underprivileged groups may put them at risk for tooth loss in adulthood.
Objectives:To evaluate the association between dental service utilization and mental health in an adult population in the context of the socioeconomic status of the participants.Subjects and Methods:Multi-stage cluster random sampling was performed in Tehran, Iran, in 2011. Data were collected on dental service utilization, barriers of dental visit, self-perceived oral health, mental health, age, gender, education, and wealth status. The complex sample analysis method in SPSS and the survey data analysis menu in STATA were employed for statistical evaluation.Results:Of 20,320 participants, 25–36% suffered from disorders in at least one of the domains of somatization, anxiety, social dysfunction, and depression. Only 56% of the participants visited a dentist at least once during the last year. The main barriers to a dental visit were “no perceived need” and “high costs.” Females, the richest participants, subjects aged 25–64-year-old, and those with poor self-perceived oral health, mental health disorders, and higher education had more visits. The participants who perceived the need but did not visit a dentist due to some reasons mostly comprised females, those aged 25–44-year-old, those with a poor perceived oral health, disordered people in all domains of mental health, and poorer participants.Conclusion:Dental service utilization was influenced by socioeconomic factors and the mental health status of the adult population after controlling for multiple confounders. Reducing financial hardship and providing health education on the importance of preventive visits may decrease barriers to regular visits in countries with developing oral health systems.
