Abstract: This study aimed to analyze the role that psychosocial elements may play concerning dental attendance and oral health in children. In particular, we explored the associations among dental fear-related cognitive vulnerability perceptions, dental prevention beliefs, the pattern of dental visits, and the number of decayed teeth. A cross-sectional design was used to collect data from 250 Spanish schoolchildren who completed a questionnaire. Oral health status was evaluated by pediatric dentists. Statistical analyses were mainly based on binary logistic regression and multiple linear regression, which allowed us to test possible associations among variables as well as interaction and mediation effects. Children with more vulnerability-related cognitions (Adj. OR = 0.74 P < 0.05) and more unfavorable dental prevention beliefs (Adj. OR = 1.47 P < 0.01) were less likely to attend the dentist regularly. Moreover, the interaction between dental prevention beliefs and cognitive vulnerability perceptions was associated with more decayed teeth (β = -0.13 P < 0.05). The irregular pattern of dental visit, associated with fearful and unfavorable dental prevention cognitions, accounted for 20% of the effects of these variables on dental caries. The combination of greater cognitive vulnerability-related perceptions and low awareness of the benefits of dental prevention increased the risk of dental caries. Children with this profile also tended to demonstrate a more inadequate pattern of dental attendance. Preventive oral health programs would benefit from considering the role of children's cognitions on their oral health habits and dental health.

Abstract: Cognitive elements play a key role in dental anxiety. Nevertheless, relatively little is known about how dental treatments and frequency of visits to the dentist are related to dental fear and its cognitive antecedents. This study aimed to explore the relationships between dental visits, past treatment experiences, expectations on the aversiveness robability of negative dental events, and dental fear in children. The participants were 147 children (60% female mean age = 12.0 yr) who completed a questionnaire comprising measures of dental treatment-related experience (attendance, fillings, and extractions), perceived aversiveness and probability of dental events, and dental anxiety. Bivariate correlations and multiple linear regression analyses were used to analyze the data. A higher frequency of dental visits was associated with less dental fear and a decreased belief in the probability of negative events occurring during treatment. The type of treatments received was not directly linked to dental fear. However, having received fillings was significantly associated with the perceived probability of negative dental events, whereas extractions were positively associated with these expectations but negatively associated with the perceived aversiveness of possible dental events. Regular dental visits, as well as dental treatments, can influence, in different ways, cognitive elements associated with dental anxiety in children.

Abstract: To explore the mechanisms by which some children select disruptive behaviours to cope with stressful dental events. In particular, the relationships between dental fear, expected effectiveness of destructive coping, and intentions of displaying uncooperative behaviours were analysed. Participants were 170 children who filled out a questionnaire survey. Descriptive statistics by gender and group age as well as comparisons of means were calculated. Spearman's rho correlation coefficients and binary logistic regression analysis were used to test hypotheses of the relationships among variables. Both dental fear and the expected effectiveness of destructive coping strategies were significantly associated with children's uncooperative intentions at the dentist. In addition, children who strongly endorsed the effectiveness of destructive coping strategies had a higher probability of uncooperative intentions as dental fear increased. In contrast, this relationship was not statistically significant among children who did not expect negative behaviours to be effective. Children's expectations about the effectiveness of destructive coping behaviours can help explain variations in the use of these strategies in stressful dental situations. Dental fear as well as children's inadequate expectancies about coping alternatives should be explored and targeted to prevent and modify uncooperative behaviour intentions at the dentist.

Abstract: Negative experiences, cognitions, and family variables are involved in the etiology of child dental fear, but previous research has frequently considered them separately. This study uses the Cognitive Vulnerability Model to explore the influence of negative dental experiences and family members on children's dental anxiety. The participants were 185 children who completed a questionnaire comprising measures of dental fear and cognitive vulnerability-related perceptions. Measures were obtained for 88 of the participants' fathers and for 97 of the participants' mothers. Cognitive vulnerability perceptions had the strongest association with children's dental fear (β = 0.40), explaining 14-21% of the variance in dental fear scores beyond that explained by other variables. Furthermore, vulnerability perceptions mediated the relationship between negative dental experiences and dental fear. Children's dental fear and cognitive vulnerability perceptions were significantly associated with those of their fathers (r = 0.23 and r = 0.40, respectively) and mothers (r = 0.28 and r = 0.35, respectively). Moreover, fathers' (β = 0.24) and mothers' (β = 0.31) levels of cognitive vulnerability significantly predicted the children's levels of dental fear. The Cognitive Vulnerability Model offers a framework to understand child dental fear. Furthermore, this cognitive approach may help explain why some children develop dental fear problems after suffering a negative dental experience and how dental anxiety is passed on from parents to children.

Abstract: To determine if temporal changes in dental fear over a 4-month period are predicted by changed cognitive vulnerability-related perceptions of going to the dentist. Australian adults (n = 484) completed mailed questionnaires at baseline and follow-up, containing measures of dental fear, cognitive vulnerability-related perceptions, dental services received, and possible aversive experiences during the study period. Change in dental fear was the main outcome measure, categorized as decreased (Fear Across the study period, 15.5 percent of people had Fear This study found, across a relatively short 4-month period, that increased vulnerability-related perceptions of visiting the dentist predicted increased dental fear while decreased vulnerability-related perceptions predicted decreased dental fear. More appropriate study designs, such as longitudinal designs, and longer follow-up periods are needed to determine the possible causal nature of these associations.

Abstract: Although previous research has successfully tested the usefulness of cognitive and non-cognitive factors to predict dental anxiety, they have rarely been jointly analysed. This study therefore aimed to compare the relative predictive power of a set of cognitive and non-cognitive factors in accounting for dental anxiety scores. A s le of 167 Spanish undergraduate students (81.4% women mean age 21.2 yr) completed a questionnaire comprising measures of dental anxiety, non-cognitive antecedents of dental anxiety (i.e. past aversive dental experiences, exposure to dentally fearful relatives, and trait-based negative mood), and cognitive variables (i.e. dental-related cognitive vulnerability, probability/aversiveness expectancies, and dental cognitions and beliefs). In multiple linear regression analyses, cognitions were found to significantly increase the proportion of variance accounted for in dental fear scores (ΔR(2) = 0.15, maximum ΔR(2) = 0.35). Cognitive factors were found to be the best in idual predictors of dental fear (β-values ranging from 0.23-0.66). Furthermore, scores for past aversive treatment experiences and negative mood were not significant predictors of scores for dental anxiety when cognitive variables were included in the models. The analysis of cognitive mechanisms involved in dental anxiety is revealed as a potentially important point in better understanding this problem.

Abstract: Recently, cognitive approaches have been successfully applied to the understanding of child dental anxiety. Our study aimed to analyze the interplay between cognitive variables and their associations with dental fear. In particular, we proposed that the observed relationship between dental treatment-related cognitive vulnerability (i.e., uncontrollability, unpredictability, dangerousness, and disgustingness appraisals) and dental fear is moderated by the expectancies of the probability and aversiveness of negative events during dental treatments. A questionnaire survey was conducted with data obtained from 179 participants (8-18 years, 55.9% female) who attended 12 randomly selected educational establishments in Madrid (Spain). Dental fear was associated with an irregular pattern of dental visits. As expected, cognitive vulnerability was strongly linked to dental anxiety. For those children who expected a lower likelihood of negative dental events or appraised them in a less aversive way, the relationship between cognitive vulnerability and fear was attenuated. As dental fear and oral health are connected, the prevention and reduction of dental fear among children and adolescents might be a worthwhile target for public health interventions. Our study sheds some light on how this could be achieved, that is, by modifying the children's vulnerability appraisals as well as their fearful dental expectancies.
