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

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.
