We aimed to evaluate (i) changes in dental fear over time during pregnancy and after delivery among mothers and fathers and (ii) whether these changes inter-relate to changes in depression and anxiety. Longitudinal pilot data for the FinnBrain Cohort study were used. Of 254 pregnant families, 80% agreed to participate and 60% returned questionnaires at the first data-collection point. After three data-collection points [weeks 18-20 and 32-34 of pregnancy (H18-20 and H32-34, respectively), and 3 months after childbirth], 99 mothers and 74 fathers had filled out at least two out of three Modified Dental Anxiety Scale questionnaires and were included in this study. Other questionnaires used were the Edinburgh Postnatal Depression Scale, the State Trait Anxiety Inventory, and the Pregnancy Related Anxiety Questionnaire. All scales were analyzed as sum scores. Among mothers, dental fear decreased during late pregnancy and increased slightly after childbirth, but no statistically significant correlations between dental fear and depression or anxiety, except for fear of giving birth, were found. Among fathers dental fear increased and was correlated with depression and anxiety. Dental fear seems to fluctuate among women during pregnancy and could be affected by hormonal changes.
This study aimed to: (i) evaluate short‐term changes in dental fear during a 9‐month period among women and men, and (ii) evaluate whether the course and magnitude of changes in dental fear were associated with changes in depression and anxiety. The longitudinal data of the FinnBrain Birth Cohort Study were used. Out of 3808 women and 2623 men, 1984 women and 1082 men filled in the Modified Dental Anxiety Scale (MDAS) at gestational weeks 14 and 34, and 3 months after childbirth. Other questionnaires used were the Edinburgh Postnatal Depression Scale and the anxiety subscale of the Symptom Checklist‐90. All scales were analyzed as sum scores. The MDAS was also trichotomized to assess the stability of dental fear. Statistical significances of the changes in dental fear, depression, and general anxiety were evaluated using repeated‐measures Friedman tests. Correlation coefficients were used to describe the associations between measures (Spearman) and their changes (Pearson). Dental fear more often increased than decreased, but for the majority it was stable. On average, dental fear, depression, and anxiety symptoms correlated throughout the study. The correlations tended to be stronger with depressive symptoms. However, the relationships between changes in dental fear, depression, and anxiety were not systematic.
We aimed to determine whether adult dental fear is associated with traumas, life events, and perceived parental bonding. Pilot data for the FinnBrain Cohort study were used. Of the 254 families expecting a baby, 80% agreed to participate. At 32-34 wk of pregnancy, 125 women and 81 men completed a Modified Dental Anxiety Scale questionnaire and were included in this study. Other instruments used were the Trauma and Distress Scale (TADS), the Life Event Checklist, and the Parental Bonding Index. All scales were analyzed as summated rating scale scores. Associations between dental fear, TADS domains, and life events were evaluated using Spearman correlation coefficients. The association between dental fear and parental bonding was evaluated using the Kruskal-Wallis test. Among women, dental fear did not correlate with trauma measures, but among men dental fear correlated with emotional neglect and abuse. Dental fear correlated positively with the number of life events among women. Life events and dental fear did not correlate among men. Dental fear was not associated with parental bonding among women or men. The association between traumas, life events, and dental fear seems to be different in women and men.
This study aimed to evaluate (i) longitudinal fluctuations and considerable changes in adult fear at five data-collection points during a 2.5-yr period and (ii) the stability of symptoms of depression in dental fear-change groups. Pilot data from the FinnBrain Birth Cohort study, of 254 families expecting a baby, were used. Data-collection points (DCPs) were: 18-20 and 32-34 gestational weeks; and 3, 12, and 24 months after delivery. At baseline, 119 women and 85 men completed the Modified Dental Anxiety Scale (MDAS) questionnaire. At all DCPs, 57 (48%) women and 35 (41%) men completed MDAS. Depression was measured using the Edinburgh Postnatal Depression Scale. Changes in MDAS were analyzed using general linear modelling for repeated measures. Stability of dental fear was assessed using dichotomized MDAS scores. Dental fear among women decreased statistically significantly in late pregnancy and increased thereafter. Among men, dental fear tended to increase in late pregnancy and decreased afterwards. Depression scores varied in high and fluctuating fear groups but the differences diminished towards the last DCP. Dental fear among adults experiencing a major life event does not seem to be stable. Clinicians should take this into account. The mechanisms behind these changes need further research.
