Internet Addiction, Oral Health Practices, Clinical Outcomes, and Self-Perceived Oral Health in Young Saudi Adults.

The study assessed the relationship between Internet addiction and oral health practices and clinical outcomes and whether this was affected by oral health perception. In 2017, a cross-sectional study included university students in the Eastern Province of Saudi Arabia. Questionnaires assessed demographic background, oral health practices (consuming sugar, tobacco use, and oral hygiene), perceived oral health, and Internet addiction. Caries experience and gingivitis were assessed using the World Health Organization criteria. The multivariate general linear analysis assessed the relationship between dependent variables (oral health practices, DMFT, and gingivitis) and exposure (Internet addiction). Data were available for 919 participants, 75.4% females, mean age = 19.8 years, and 1.6% with significant Internet use problem. The mean percentage of teeth with gingivitis was 8.5% and mean DMFT was 2.9. Among those with good perception of oral health and compared with participants with significant Internet use problem, average Internet users had lower consumption of sugar and tobacco (B = -6.52, P = 0.03 and B = -2.04, P = 0.03), better oral hygiene practices (B = 2.07, P = 0.33), higher DMFT (B = 2.53, P = 0.10), and lesser gingivitis (B = -15.45, P = 0.06). Internet addiction was associated with negative oral health practices and poor clinical outcomes among young Saudis. Holistic health promotion approaches need to address the negative impact of Internet addiction on health and oral health status for this at-risk age group.

Dental expenditure and catastrophic dental expenditure in Eastern Saudi Arabia: Pattern and associated factors.

BACKGROUND: Dental services have one of the highest expenses among health services. The aims of the study were to assess (1) dental expenditure (DE), (2) catastrophic dental expenditure (CDE), (3) dental services payment and (4) factors associated with DE and CDE. MATERIAL AND METHODS: A cross sectional study was conducted in 2018 in Saudi Arabia. Using convenience sample, participants were recruited from governmental and private dental clinics/hospitals. A questionnaire assessed (a) personal information, (b) dental background: payment methods, type of clinics visited, perceived oral health status, frequency of pain and (c) payment for dental services received. The number of remaining teeth was clinically assessed. Two outcome variables were assessed (1) total DE in linear regression and (b) CDE (DE exceeds 10% of income) in logistic regression. Personal and dental background variables were explanatory variables. RESULTS: The response rate was 83.8% (419/500) with 43% reporting expenditure, 16.5% facing CDE and 36.3% using multiple payment methods. The greatest DE was for crowns and bridges, root canal therapy, fillings and implants. Income, payment method and pain were associated with DE and CDE. CONCLUSIONS: Participants used multiple payment methods including out of pocket and faced CDE. The bulk of expenditure was for rehabilitative services. The availability and quality of health-insured primary care services may reduce the financial burden facing dental patients.
