The sample consisted of 63 parents/guardians of schoolchildren from the municipal school system of Teófilo Otoni, MG. Remote and virtual data collection consisted of self-completion of personal data, socioeconomic questionnaire and the Brazilian short versions of the \"Parental-Caregiver Perceptions Questionnaire\" (16-P-CPQ) and the \"Family Impact Scale\" (4-FIS). The IPQ-RD was applied by telephone interview. Almost half of the sample belonged to socioeconomic classes C1 and C2. Approximately 1/3 classified their child's oral health as \"regular\" or \"poor\", while 11.1% reported \"strong\" or \"very strong\" impact on their child's well-being. The items most frequently cited as having an impact on the four domains of the 16-P-CPQ were: \"bad breath\" (23.8%), \"mouth breathing\" (20.7%), \"feeling anxious or afraid\" (20.7%), and \"paying attention at school\" (10%). In the 4-FIS, 11.1% \"had little time for themselves or the family\". There were higher IPQ-RD scores in the \"disease coherence\" domain for women and lower values of \"emotional dimensions\" for parents/guardians with incomplete education. The mean IPQ-RD score was 126.4 (±15.1), and domain scores were positively correlated. The internal consistency was \"almost perfect\" for the IPQ-RD total score, ranging from \"moderate\" to \"almost perfect\" for the \"child-control\" and \"child-consequences\" domains.
