Self-reported oral and general health in relation to socioeconomic position.

BACKGROUND: During the past two decades, several scientific publications from different countries have shown how oral health in the population varies with social determinants. The aim of the present study was to explore the relationship between self-reported oral and general health in relation to different measures of socioeconomic position. METHODS: Data were collected from a randomly selected sample of the adult population in Sweden (n = 3500, mean age 53.4 years, 53.1% women). The response rate was 49.7%. Subjects were interviewed by telephone, using a questionnaire including items on self-reported oral and general health, socioeconomic position and lifestyle. RESULTS: A significant gradient was found for both oral and general health: the lower the socioeconomic position, the poorer the health. Socioeconomic position and, above all, economic measures were strongly associated with general health (OR 3.95) and with oral health (OR 1.76) if having an income below SEK 200,000 per year. Similar results were found in multivariate analyses controlling for age, gender and lifestyle variables. CONCLUSIONS: For adults, there are clear socioeconomic gradients in self-reported oral and general health, irrespective of different socioeconomic measures. Action is needed to ensure greater equity of oral and general health.

Dental care attendance and refrainment from dental care among adults.

OBJECTIVE: The aim of this study was to analyse dental care utilization, refrainment from self-perceived needed dental care and the association with socioeconomic indicators among adult individuals. MATERIALS AND METHODS: This cross-sectional survey included 3500 randomly selected adult individuals. Telephone interviews were conducted and the participants answered a battery of questions regarding dental visiting habits, health, socioeconomic position (SEP), behavioural factors and lifestyle indicators. RESULTS: The outcome 'dental visits' was significantly correlated with SEP, especially with monetary dimensions, such as income and economic resources for unforeseen expenditures. However, educational level was not a significant predictor in the tested statistical models. Furthermore, other covariates that contributed significantly to the models were ethnicity, dental anxiety and lifestyle factors, albeit with a different pattern of impact on the two outcome dimensions. Important features of the SEP variables were the stepwise gradient relative to the outcomes, implicating that the lower the SEP status, the greater the risk of reporting irregular dental visiting habits and refraining from dental care due to financial problems. CONCLUSIONS: Dental care utilization and refraining from dental care for financial reasons clearly reveal associations with socioeconomic positions among adult individuals.

Translation and psychometric properties of the Swedish version of the Index of Dental Anxiety and Fear (IDAF-4C⁺).

Dental anxiety (DA) is a common condition, with significant medical, psychological, and social consequences. High-quality psychometric tools for the assessment of dental anxiety are necessary for clinical and research purposes. The aim of this study was to adapt the Index of Dental Anxiety and Fear (IDAF-4C(+) ) to the Swedish language and to explore the psychometric properties of the translated version. The study included a clinical sample (n = 414; 17-91 yr of age) and a non-clinical sample (n = 51; 19-47 yr of age). The scales used were the IDAF-4C(+) , the Single-Question Assessment of Dental Anxiety (SQDA), the Dental Fear Survey (DFS), and the Internal Health Locus of Control (IHLOC). The Swedish IDAF anxiety module showed a clear, one-dimensional structure, good internal consistency (Cronbach's alpha = 0.95), and adequate validity, as evidenced by strong correlations with the other DA measures (SQDA and DFS) and weak correlations with the IHLOC. In addition, the IDAF phobia module and the IDAF stimulus module were strongly correlated with the other DA measures. To conclude, the study shows promising findings for the reliability and validity of the Swedish translation of the IDAF-4C(+) , as a useful measure of dental anxiety in research and clinical practice.

Associations between dental anxiety, sense of coherence, oral health-related quality of life and health behavior--a national Swedish cross-sectional survey.

BACKGROUND: Dental anxiety (DA) is a common condition associated with avoidance of dental care and subsequent health-related and psychosocial outcomes, in what has been described as the vicious circle of DA. Also, recent studies have found an association between the psychosocial concept of sense of coherence (SOC) and DA. More studies are needed to verify the relationship between DA and SOC, especially using population-based samples. There is also a need for studies including factors related to the vicious circle of DA, such as oral health-related quality of life (OHRQoL), in order to further establish the correlates of DA in the general population. Therefore, the aim of this study was to investigate the relationship between DA and SOC, OHRQoL and health-related behaviour in the general Swedish population. METHODS: The survey included a randomly selected sample of the adult Swedish population (N = 3500, age 19 - 96 years.). Data was collected by means of telephone interviews. Dental anxiety was measured with a single question. The SOC measure consisted of three questions conceptualising the dimensions of the SOC: comprehensibility, manageability and meaningfulness. The data collection also included the five-item version of the Oral Health Impact Profile (OHIP-5), as a measure of OHRQoL, as well as questions on oral health-related behaviour and socioeconomic status. Statistical analyses were made with descriptive statistics and inference testing using Chi-square, t--test and logistic regression. RESULTS: High DA was associated with low OHRQoL, irregular dental care and smoking. There was a statistically significant relationship between the SOC and DA in the bivariate, but not in the multivariate, analyses. Dental anxiety was not associated with oral health-related behaviour or socioeconomic status. CONCLUSIONS: This cross-sectional national survey gives support to the significant associations between high dental anxiety, avoidance of dental care and health-related outcomes, which may further reinforce the model of a vicious circle of dental anxiety. The results further indicate a weak relationship between dental anxiety and sense of coherence.

Orofacial esthetics and dental anxiety: associations with oral and psychological health.

OBJECTIVE: Severe dental anxiety (DA) is associated with both oral health and psychosocial consequences in what has been described as a vicious circle of DA. The aim of this study was to investigate self-rated orofacial esthetics in patients with DA and its relationship to psychological and oral health. MATERIALS AND METHODS: A consecutive sample of 152 adult patients who were referred or self-referred to a specialized dental anxiety clinic filled out the Orofacial Esthetic Scale (OES) as well as measurements on DA, self-rated oral health and general anxiety and depression. Clinical measures of dental status were also obtained. RESULTS: Compared with the general population, patients with DA had lower ratings of satisfaction on all aspects of their orofacial esthetics, which included the teeth, gingiva, mouth and face, as well as a global orofacial assessment. Furthermore, the perception of the orofacial appearance was related both to dental status and self-rated oral health, as well as to general anxiety and depression. The level of dissatisfaction with the orofacial appearance was similar for both genders, but women reported more regular dental care and better dental status. CONCLUSIONS: The results of this study clearly show less satisfaction with dental and facial appearance in patients with DA, and that the self-rating of orofacial esthetics is related to both oral and psychological health. The OES can be used to assess orofacial esthetics in patients with DA.

An explorative analysis of the recruitment of patients to a randomised controlled trial in adolescents with dental anxiety.

Randomised controlled trials (RCTs) are considered to provide the most reliable evidence on the efficacy of interventions. The aim of this study was to describe the recruitment process of an RCT study set up to evaluate a Cognitive Behavioural Therapy (CBT) intervention programme for adolescent patients with dental anxiety (DA). The participants were recruited from a consecutive sample of adolescent patients (12-19 yrs old) referred for DA to a specialised pediatric dentistry clinic. Age, gender, and reason for referral were recorded for the possible eligible patients as part of the drop-out analysis of the recruitment process. Participants were then randomized to the intervention (CBT integrated with dental treatment) or control (adapted dental treatment) condition. In the recruitment process, 138 possible eligible patients met inclusion criteria, of these 55 were enrolled, 44 declined participation and 39 patients were excluded.The patients enrolled in the RCT did not differ from the non-participants with regard to age, gender or cause of referral. As a result of difficulties in the recruitment process, the study period was extended. The considerable proportion of non-participants as evident from the recruitment process may pose a threat to the external validity of the clinical trial. From a clinical perspective, the reasons for the lack of motivation to participate in behavioural interventions and the failure to appear warrant further investigation.

Dental anxiety - a joint interest for dentists and psychologists.

This introductory article to the Symposium on Behavioral and Community Dentistry aims to describe the development of research and clinical work on dental anxiety, and includes a discussion of the historical background and the evolution since the 1970s. In view of its pioneering activities in this regard, special focus is placed on research and development at the Institute of Odontology of the University of Gothenburg, Sweden.

Psychological treatment of dental anxiety among adults: a systematic review.

The aim was to investigate the efficacy of behavioural interventions as treatment of dental anxiety/phobia in adults, by conducting a systematic review of randomized controlled trials (RCTs). The inclusion criteria were defined according to the Patients, Interventions, Controls, Outcome (PICO) methodology. The study samples had documented dental anxiety, measured using validated scales [the Dental Anxiety Scale (DAS) or the Dental Fear Survey (DFS)], or fulfilled the psychiatric criteria for dental phobia. Behavioural interventions included were based on cognitive behavioural therapy (CBT)/behavioural therapy (BT), and control conditions were defined as information, sedation, general anaesthesia, and placebo/no treatment. The outcome variables were level of dental anxiety, acceptance of conventional dental treatment, dental treatability ratings, quality of life and oral health-related quality of life, and complications. This systematic review identified 10 RCT publications. Cognitive behavioural therapy/behavioural therapy resulted in a significant reduction in dental anxiety, as measured using the DAS (mean difference = -2.7), but the results were based on low quality of evidence. There was also some support that CBT/BT improves the patients' acceptance of dental treatment more than general anaesthesia does (low quality of evidence). Thus, there is evidence that behavioural interventions can help adults with dental anxiety/phobia; however, it is clear that more well-designed studies on the subject are needed.

Attention deficit hyperactivity disorder and dental anxiety in adults: relationship with oral health.

The aim of the present study was to investigate the presence of attention deficit hyperactivity disorder (ADHD) in adult patients with severe dental anxiety. Specifically, we analysed the relationship among ADHD, oral health, and dental anxiety. The World Health Organization Adult ADHD Self-Report Scale (ASRS) Screener was administered to a consecutive sample of patients referred to a dental fear research and treatment clinic. Patients completed questionnaires measuring dental anxiety (Dental Fear Survey) and self-rated oral health, and underwent a full radiographic examination. Of the total sample (n = 110), 16% scored above the established ASRS cut-off point, which is indicative of having ADHD. The ADHD group showed a higher level of dental anxiety and poorer self-rated oral health. There were also indications of poorer clinical oral health in the ADHD group, but these results did not reach statistical significance. In conclusion, the results of this study indicate an increased prevalence of ADHD in highly dentally anxious adults and the need to pay special attention to these patients because of greater treatment needs and increased dental anxiety.

General fearfulness, attitudes to dental care, and dental anxiety in adolescents.

The etiology of dental anxiety (DA) may involve a spectrum of factors related to past dental experiences, general and specific fears, and other personality factors, but is relatively unexplored in adolescents. The aim of this study was to examine how general fearfulness and attitudes to dental care/personnel were related to DA in 15-yr-old subjects. The sample included 263 randomly selected 15-yr-old adolescents living in the municipality of Jönköping in southern Sweden. Four questionnaires were used: one general questionnaire regarding background data and three psychometric instruments dealing with DA, general fearfulness, and dental beliefs. Of all participants, 6.5% were classified as having DA. Dental anxiety was moderately to strongly correlated both with attitudes to dental care/personnel and with general fearfulness and indicated the strongest impact for individuals with both high general fearfulness and high dental beliefs in relation to DA. The linear multiple regression analysis showed that the best predictors of DA were general fearfulness and dental beliefs. This suggests that both individual vulnerability in terms of generalized fear and apprehensions about dental staff, which is linked to experiences of dentistry, appear to be important factors for DA and may be considered as risk factors for DA in adolescents.

Dental anxiety and temperament in 15-year olds.

OBJECTIVE: The aim of the present study was to analyze the prevalence of dental anxiety and its association with temperament, sociodemographic factors and previous painful and unpleasant experiences of dental care among 15-year old individuals. MATERIALS AND METHODS: The sample included 263 randomly selected 15-year old individuals living in the municipality of Jönköping, Sweden. The school, parental and adolescent consent was acquired. Three self-reported questionnaires were used, one included items of sociodemography, while the others dealt with dental anxiety assessed by the Dental Fear Survey (DFS) and temperament assessed by an adapted version of The EAS Temperament Survey for Children modified for adults, the EASI temperament survey. RESULTS: The results showed that 6.5% of the adolescents were classified as dentally anxious and with girls proportionally more fearful than boys. The three temperaments activity, impulsivity and emotionality were significantly correlated with dental anxiety. A hierarchical multiple linear regression analysis showed that pain at the last dental appointment or previous pain experiences during dental care treatment were the strongest predictors regarding dental anxiety in 15-year olds. The temperament dimensions activity and impulsivity were also significantly predictive of dental anxiety. CONCLUSIONS: Although some of the temperament dimensions are correlated with dental anxiety, which may emphasize an important finding with regard to personality, this study showed that previous pain experiences during dental care treatment is a strong predictor for high dental anxiety in 15-year olds.
