To explore differences in possible bruxism, state anxiety, coping and parenting styles between a group of divorced parents and a group of cohabiting parents.Patients and Methods: A cross-sectional study was conducted, with data collected through self-report questionnaires filled in by 186 patients (8– 16 years) and their parents. Children completed State Trait Anxiety Inventory (STAI), Self-Report Coping Measure (SRCM) and Parenting Style Scale. The Self-Reported Bruxism Questionnaire (SBQ) was completed by their parents.Results: The results showed significant differences were seen between the group of divorced parents (n=93) and the control group (n=93), with higher levels of state anxiety and possible bruxism in the group of children of divorced parents. In addition, in terms of coping strategies, externalisation and problem-solving deficits stood out. In terms of parenting style, autonomy promotion was higher. Additionally, possible bruxism was influenced by coping strategies (seeking social support), attachment-based parenting style and communication, behavioural control and state anxiety. Finally, it was found that high anxiety may act as a moderating variable in the relationship between divorced parents and possible bruxism.Conclusion: Children of divorced parents showed more possible bruxism, anxiety, coping and behavioural problems.Keywords: divorced parents, anxiety, bruxism, coping
