Disparities in dental health issues and oral health care visits in US children with tobacco smoke exposure.

BACKGROUND: The objective of the authors was to assess the relationships between tobacco smoke exposure (TSE) and dental health and dental care visits among US children. METHODS: The authors examined 2018-2019 National Survey of Children's Health data on TSE, dental health, and oral health care visits. Children aged 1 through 11 years (N = 32,214) were categorized into TSE groups: no home TSE (did not live with a smoker), thirdhand smoke (THS) exposure (lived with a smoker who did not smoke inside the home), or secondhand smoke (SHS) and THS exposure (lived with a smoker who smoked inside the home). The authors conducted multivariable logistic regression analyses, adjusting for child age, sex, race or ethnicity, prematurity, caregiver education level, family structure, and federal poverty threshold. RESULTS: Children with home SHS and THS exposure were at increased odds of having frequent or chronic difficulty with 1 or more oral health problem (adjusted odds ratio [AOR], 1.59; 95% CI, 1.07 to 2.35; P = .022) and carious teeth or caries (AOR, 1.74; 95% CI 1.14 to 2.65; P = .010) than those with no TSE. Compared with children aged 1 through 11 years with no TSE, children with SHS and THS exposure were 2.22 times (95% CI, 1.01 to 4.87; P = .048) more likely to have not received needed oral health care but at decreased odds of having had any kind of oral health care visit (AOR, 0.55; 95% CI, 0.32 to 0.95; P = .032), including a preventive oral health care visit (AOR, 0.60; 95% CI, 0.36 to 0.99; P = .047). CONCLUSIONS: TSE in children is associated with caries and inadequate oral health care visits. PRACTICAL IMPLICATIONS: The pediatric dental visit is an opportune time to educate caregivers who smoke about dental health to improve their children's teeth condition and increase oral health care visits.
