Reducing dental fear would increase the number of regular attenders, especially among older age groups. Individuals for whom oral health services have been provided regularly since childhood seem to continue to use these services regularly despite high dental fear.
We studied the association between dental fear and anxiety or depressive disorders, as well as the comorbidity of dental fear with anxiety and depressive disorders, controlling for socio-demographic characteristics, dental attendance, and dental health. Nationally representative data on Finnish adults, ≥ 30 yr of age (n = 5,953), were gathered through interviews and clinical examination. Dental fear was measured using the question: 'How afraid are you of visiting a dentist?' Anxiety and/or depressive disorders were assessed using a standardized structured psychiatric interview according to criteria presented in the Diagnostic and Statistical Manual of Mental Disorders (4th edition) (DSM-IV).Those with depressive disorders, generalized anxiety disorder or social phobia more commonly reported high dental fear than did those without these disorders. When age, gender, education, dental attendance, and the number of decayed, missing, and restored teeth were considered, those with generalized anxiety disorder were more likely to have high dental fear than were participants with neither anxiety nor depressive disorders. The comorbidity of depressive and anxiety disorders also remained statistically significantly associated with dental fear; those with both depressive and anxiety disorders were more likely to have high dental fear than were those without these disorders. Our findings support the suggestion that some individuals may have a personality that is vulnerable to dental fear.
Dental fear is still common among adult Finns and it seems to depend on age. As the most obvious consequence of dental fear is avoidance of dental care, reducing dental fear should be taken into account when planning and reorienting oral healthcare services.
The aim of our study was to compare the changes in children's oral health-related behavior, knowledge, and attitudes obtained using an oral health-promotion approach, a risk-strategy and promotion approach, and reference area, and to report changes in the behavior of children between the experimental and the control groups of a randomized clinical trial (RCT). The study population consisted of all fifth and sixth graders who started the 2001-2002 school year in Pori, Finland (n = 1,691), where the RCT and program of oral health promotion were implemented for 3.4 yr. Children with at least one active caries lesion were randomly assigned to experimental (n = 250) and control (n = 247) groups. Children in Rauma (n = 807) acted as the reference. Changes in children's self-reported behavior, knowledge, and attitudes were compared between groups. The subjects in the oral health-promotion group and in the risk-strategy and promotion group in Pori tended to show greater improvement in most of their oral health-related behaviors than those in the reference group, and children in the RCT experimental group showed greater improvement in most of their oral health-related behaviors than those in the RCT control group. Children can be helped to improve their oral health-related behavior by intervention, including oral hygiene and dietary counseling, or by implementing a multilevel-approach oral health-promotion program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
