Association of depression and anxiety with different aspects of dental anxiety in pregnant mothers and their partners.

OBJECTIVES: The aim was to confirm the factor structure of Modified Dental Anxiety Scale (MDAS) and to investigate whether the association of these factors with general anxiety and depression varied across gender. METHODS: The FinnBrain Birth Cohort Study (www.finnbrain.fi) data from the first collection point at gestational week 14 were used. Of the invited participants (n = 5790), 3808 (66%) expectant mothers and 2623 fathers or other partners of the mother agreed to participate, and 3095 (81.3%) mothers and 2011 (76.7%) fathers returned the self-report questionnaire. Dental anxiety was measured with the MDAS, general anxiety symptoms with Symptom Checklist-90 (anxiety subscale) and depressive symptoms with the Edinburgh Postnatal Depression Scale. Multiple group confirmatory factor analysis (MGCFA) was conducted to test the equivalence of the factor structure and multiple group SEM (MGSEM) to test the configural invariance (unconstrained model) and metric invariance (structural weights model), across genders. RESULTS: Of those consenting, 3022 (98%) women and 1935 (96%) men answered the MDAS. The MGCFA indicated good convergent validity for the two-factor model for MDAS, but somewhat low discriminant validity (factors demonstrated 72% shared variance). The MDAS items loaded clearly higher for the assigned factor than to the other factor (differences in loadings >0.2), indicating that the 2-factor model has merit. According to the final MGSEM model, anxiety symptoms were directly related to anticipatory dental anxiety, but not to treatment-related dental anxiety. CONCLUSIONS: When assessing dental anxiety with MDAS, considering also its two factors may help clinicians in understanding the nature of patient's dental anxiety.

Attitudes towards tooth fillings in Tanzanian adults and its association with previous filling experience.

BACKGROUND: Tooth filling treatment is utilized at low levels in many low and middle-income countries (LMICs), further, little is known about the prevailing attitudes towards such treatment. This study aimed to assess attitudes towards tooth filling among Tanzanian adults and how previous tooth filling experience is associated with these attitudes. METHODS: A pretested structured questionnaire was distributed among 1522 out-patients in four regional hospitals in Tanzania in 2015-16. The questionnaire had eight statements on a 6-point Likert scale measuring attitudes towards tooth filling. Responses were analyzed independently and through a constructed attitude sum score. Linear regression analysis was used to assess the association of previous tooth fillings on attitudes towards tooth filling treatment. RESULTS: The respondents were mostly female (57.3%), with a mean age of 33.1 years (SD 11.3). About one third of the respondents (36.4%) had primary level of education. Attitudes towards tooth filling treatment were generally negative. Low levels of education and income were associated with more negative attitudes. A small proportion (11.5%) had a previous tooth filling. Having a previous tooth filling was associated with a more positive attitude towards tooth fillings regardless of socioeconomic status. CONCLUSIONS: This study shows that even in areas with limited resources and availability of services, previous experience of tooth fillings is related to more positive attitudes towards restorative treatment, which should be taken into account when planning oral health care programs.

The relative patient costs and availability of dental services, materials and equipment in public oral care facilities in Tanzania.

BACKGROUND: Patient charges and availability of dental services influence utilization of dental services. There is little available information on the cost of dental services and availability of materials and equipment in public dental facilities in Africa. This study aimed to determine the relative cost and availability of dental services, materials and equipment in public oral care facilities in Tanzania. The local factors affecting availability were also studied. METHODS: A survey of all district and regional dental clinics in selected regions was conducted in 2014. A total of 28/30 facilities participated in the study. A structured interview was undertaken amongst practitioners and clinic managers within the facilities. Daily resources for consumption (DRC) were used for estimation of patients' relative cost. DRC are the quantified average financial resources required for an adult Tanzanian's overall consumption per day. RESULTS: Tooth extractions were found to cost four times the DRC whereas restorations were 9-10 times the DRC. Studied facilities provided tooth extractions (100%), scaling (86%), fillings (79%), root canal treatment (46%) and fabrication of removable partial dentures (32%). The ratio of tooth fillings to extractions in the facilities was 1:16. Less than 50% of the facilities had any of the investigated dental materials consistently available throughout the year, and just three facilities had all the investigated equipment functional and in use. CONCLUSIONS: Dental materials and equipment availability, skills of the practitioners and the cost of services all play major roles in provision and utilization of comprehensive oral care. These factors are likely to be interlinked and should be taken into consideration when studying any of the factors individually.

Exploring the associations between somatization and dental fear and dental visiting.

While somatization has been investigated as an important variable in relation to excessive health-service utilization, its role in relation to dental visiting and dental fear has received limited attention. It was hypothesized that an excessive focus on physical symptoms might lead somatizers to experience dental treatment as more traumatic, resulting in greater dental fear. The aims of this study were to determine whether somatization was associated with dental fear, reduced dental visiting, and symptomatic visiting. Questionnaire data were collected from 5,806 dentate Finnish adults, with somatization measured using 12 items from the Symptom Check List (SCL-90). Dental fear was measured using a single-item question and dental visiting was assessed by questions relating to time since last dental visit and the usual reason for dental visiting. Multinomial logistic regression analyses indicated that somatization has a statistically significant positive association with both dental fear and symptomatic dental visiting after controlling for age, gender, and education. However, the association between dental-visiting frequency and somatization was not statistically significant. The results were consistent with the hypothesized role of somatization in the development of dental fear. Further investigation of how somatization is related to dental fear and dental-service utilization appears warranted.
