In Vietnam, evidence linking caregivers\u2019 oral health knowledge to children\u2019s oral health remains limited. Therefore, this study aimed to cross-culturally adapt and validate a caregiver oral health knowledge questionnaire for Vietnamese use and investigate its association with oral health status among children and adolescents with ASD.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods<\/jats:title>\n                    <jats:p>A questionnaire on caregivers\u2019 oral health knowledge was validated through a pilot study using Cronbach\u2019s alpha coefficient and exploratory factor analysis. A cross-sectional study included 170 children and adolescents with ASD and their caregivers. Participants received oral examinations assessing dmft\/DMFT, and DI-S. Group differences were analyzed using nonparametric tests. Multivariable negative binomial regression models were applied for dmft and DMFT, and linear regression for DI-S. Significance was set at p &lt; 0.05.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The questionnaire demonstrated acceptable reliability (Cronbach\u2019s alpha = 0.73) and mainly unidimensional structure. Higher caregiver knowledge was significantly associated with better oral hygiene (p &lt; 0.001), no association with dmft, and inconsistent associations with DMFT. Age was strongly associated with DMFT (p &lt; 0.001). Household income was the only sociodemographic factor significantly associated with outcomes.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>A caregiver oral health knowledge questionnaire underwent cross-cultural adaptation and validation for use in Vietnam.
