Factors associated with dental clinic use by clients in Nigeria during the COVID-19 pandemic.

BACKGROUND: Nigeria, like many other countries, faced challenges in dental care provision during the COVID-19 pandemic, necessitating limited care to emergencies only. However, the impact of restricted access to dental services on oral health remains a concern, particularly with preventive maintenance care. This study aims to identify the factors associated with dental service utilization during the COVID-19 pandemic among patients attending dental clinics in Nigeria, and their sources of information about COVID-19. METHODS: This cross-sectional study recruited 500 participants who had visited dental clinics before and during the pandemic. Data were collected through telephone interviews and online questionnaires between September and December 2021. Inferential analyses were conducted using ordered logistic regression models to assess the association between the independent (awareness of emergency dental treatments, knowledge of COVID-19 transmission routes in dentistry, awareness of required preparations in dental practice settings, fear of COVID-19 infection in dental settings), and dependent (utilization of dental services during the pandemic) variables after adjusting for confounding variables (age, sex, educational status, COVID-19 vaccinations status and COVID-19 status of live-in residents). The sources of COVID-19 information by dental patients was also identified. Statistical significance was established at 95% confidence level with a p value < 0.05. RESULTS: Many participants were males (51.2%) and had tertiary education (61.6%). Fear of COVID-19 infection in dental settings was significantly associated with lower odds of utilizing dental care services during the pandemic (Adjusted Odds Ratio: -0.06, 95% Confidence Interval: -0.08, -0.01). The main sources of COVID-19 information were mass media and social networks, with only 42% receiving information from dental professionals. CONCLUSION: Fear of COVID-19 infection in dental settings significantly influenced dental service utilization during the pandemic. Strategies to address fear and improve communication channels between dental professionals and patients are essential for promoting oral health during similar crises.

Oral health and treatment needs among 18-year-old Iranians.

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.

Oral health among 35- to 44-year-old Iranians.

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, chi(2) 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.
