RESUMEN
ABSTRACT Objective: To investigate the influence of parental depression and substance use in the oral health care of children with disabilities. Material and Methods: A cross-sectional study was conducted involving 151 children with disabilities and their parents/caregivers. To detect the presence of depression and alcohol or tobacco use, the parents/caregivers answered three questionnaires: two versions of the Patient Health Questionnaire (PHQ), AUDIT (Alcohol Use Disorders Identification Test), and the Fagerstrom Test for Nicotine Dependence (FTND). Then, the children with disabilities underwent oral examination to evaluate biofilm control, gingival condition and the dental carie index (decayed, missing, and filled teeth - dmft ̸ DMFT). Results: There was a statistically significant association between tobacco use and dental caries in deciduous teeth (p=0.046). The children of smokers had six times greater need for dental treatment than that of non-smokers (OR= 6.36; CI= 1.3-30.5). There was no statistically significant association between the oral health of the children with disabilities and parental alcohol consumption and depression (p>0.05). Children with medical condition had a higher need for dental treatment than children with intellectual disability (p=0.003). Conclusion: Parental smoking habits increase dental caries in the deciduous teeth of children with disabilities, but parental depression and alcohol use do not influence the oral health of children with disabilities. Children with medical condition have more treatment needs than children with intellectual disability.
