Examining the association between untreated caries in children and parent fluoride treatment refusal.

ABSTRACT

BACKGROUND: In this case-control study, the authors examined the relationship between untreated caries in children and parent fluoride treatment refusal. The authors hypothesized that parents of children with a history of untreated caries would be less likely to refuse topical fluoride for their children than parents of children with no history of untreated caries. METHODS: The study included children (≤ 18 years old) who were patients at a university dental clinic from January 2016 through June 2020. Children whose parents refused fluoride treatment were age-matched with children whose parents did not refuse fluoride treatment (n = 356). The outcome variable was parent topical fluoride refusal for their children (no, yes). The predictor variable was a history of untreated caries (no, yes). Confounding variable-adjusted modified Poisson regression models were used to estimate the prevalence ratio of parent fluoride refusal by means of children's untreated caries status. RESULTS: Approximately 46.3% of children had a history of untreated caries. The prevalence of parent fluoride refusal for children with a history of untreated caries was significantly lower than that for children with no history of untreated caries (adjusted prevalence ratio, 0.79; 95% CI, 0.64 to 0.98; P = .03). CONCLUSIONS: Parents of children with a history of caries are less likely to refuse topical fluoride treatment, which suggests that untreated caries may motivate parents to accept preventive dental treatments like fluoride. PRACTICAL IMPLICATIONS Dental care professionals should assess caries risk and communicate a child's caries risk before making a recommendation regarding topical fluoride treatment.
