Objectives

This cross-sectional study aimed to examine the associations between parental acculturation level and strategies and children's caries experience and oral health (OH) behaviors.

Methods

Participants were immigrant parents of children aged 2–12 years. Data were collected by validated questionnaires gathering information on socio-demographics, child's OH behaviors, and parents'; acculturation and dental examinations determining child's caries experience using DMFT/dmft index. Univariate and multivariate regression analyses were used.

Results

Three hundred and thirty-six parent/child dyads completed the study. Length of residency (B = 0.103; 95% CI: 0.064, 0.141) parents' education (B = 1.691; 95% CI: 1.228, 2.155), and household income (B = −0.959; 95% CI: −1.566, −0.352) significantly predicted acculturation level. Parents with high Canadian cultural knowledge reported higher frequency of children's toothbrushing (p-value = 0.015). Parents of children who consumed sugar >1/day had higher mean scores of acculturation to Canadian culture (p-value = 0.016), English language proficiency (p-value = 0.024), and Canadian food adoption (p-value = 0.046). Parents of children who visited the dentist within last 12 months had significantly higher assimilation and lower separation mean scores. Parents of children who visited dentist because of dental problems had higher marginalization mean score than those who went for check-ups (p-value = 0.046). Parental acculturation was not significantly correlated with their children's dmft/DMFT level.

Conclusions

Children of highly acculturated parents reported higher toothbrushing frequency and were more likely to consume sugar than children of less acculturated parents. Assimilated parents reported more and marginalized parents reported less favorable OH behaviors than other categories. Parental acculturation level or strategy was not associated with children's caries experience.
