Psychometric Properties of the Hebrew Modified Dental Anxiety Scale in Adult Israeli Population

Influence of experiencing SARS-CoV-2 infection on anxiety levels in Chinese patients undergoing third molar surgery

Background

In China, most of the citizens experienced SARS-CoV-2 infection since the end of 2022. The Coronavirus disease 2019 (COVID-19) pandemic affected people's physical health and also had a significant impact on mental well-being. The present study aims to discover if the experience of SARS-CoV-2 infection influences patients' anxiety toward third molar surgery in the Chinese population.

Materials and methods

The present study took the form of a questionnaire survey. From January 1, 2023, to June 30, 2023, patients who went to the Stomatology Center of China-Japan Friendship Hospital (Beijing, China) for the third molar extraction were included according to the inclusion criteria. The information on COVID-19 infection and the Modified Dental Anxiety Scale (MDAS) was collected. The software SPSS 22.0 was used for the statistical analyses.

Results

A total of 574 survey results were harvested in the present study. The infection rate of COVID-19 was 86.6% (p > 0.05). The Average MDAS scores between patients who had been infected with COVID-19 and patients who were never infected were not significantly different (11.65 ± 4.41 vs. 11.42 ± 4.41, p > 0.05). The subgroup analysis was conducted according to the length of time after the recovery of COVID-19 (Model 1), and the highest temperature during the infection (Model 2). In Model 1 and Model 2, the one-way ANOVA test did not find statistical significance between the groups (Model 1 p = 0.114; Model 2 p = 0.481). The MDAS scores in female patients were significantly higher than in male patients (12.29 ± 4.53 vs. 9.91 ± 3.80, p < 0.001). Patients who extracted double teeth got significantly higher MDAS scores than those who extracted single teeth before the surgery (12.03 ± 4.74 vs. 11.24 ± 4.18, p = 0.037).

Conclusion

The present study did not establish a significant impact of SARS-CoV-2 infection on the anxiety levels associated with third molar surgery among Chinese patients. The potential long-term biopsychological effects of the virus warrant further investigation.

Dental anxiety and ageing anxiety: Moderated mediation roles of Oral Health-Related Quality of Life and subjective accelerated ageing

BACKGROUND

Oral health and its relation to ageing is an important topic often neglected among geriatric populations. Proper oral rehabilitation may aid in alleviating mental health burdens in such populations.

OBJECTIVES

The present study aimed to explore the association between dental anxiety and ageing anxiety, with regard to the interplay of Oral Health-Related Quality of Life (OHRQoL) as mediator and subjective accelerated ageing as a moderator.

METHODS

A total of 577 participants with mean age 72.78 years (SD = 3.832, range = 68-87) were recruited via a survey company in Israel. They completed a self-report battery of questionnaires about dental anxiety, OHRQoL, subjective accelerated ageing and ageing anxiety, along with their informed consent.

RESULTS

The findings revealed that dental anxiety was positively associated with ageing anxiety (direct effect), and that OHRQoL mediated the link between dental anxiety and ageing anxiety (indirect effect). Additionally, subjective accelerated ageing moderated the positive link between dental anxiety and OHRQoL, as well as the positive link between OHRQoL and ageing anxiety.

CONCLUSIONS

The results provide insight for the roles of OHRQoL and subjective accelerated ageing among older adults between dental anxiety and ageing anxiety. Tailoring oral rehabilitation interventions that focus on these factors are warranted to improve older adults' dental health.

Unveiling the Association between Body Image Dissatisfaction and Dental Anxiety

Background: Increased demands for invasive and non-invasive treatments related to body image disturbances are seen worldwide. These demands may be related to body image dissatisfaction. No study to date investigated the relationship between body image dissatisfaction and dental anxiety (namely, anticipatory dental anxiety and treatment dental anxiety) among a non-clinical population. The current study aims to unveil such relationships. Methods: Dentally anxious people may choose to ‘cope’ with their anxiety via unnecessary invasive procedures related to their body image dissatisfaction. In the current study, 553 individuals completed an online survey assessing their dental anxiety, dental neglect, and body image via self-report questionnaires. Results: Body image dissatisfaction was significantly correlated with dental anxiety. In contrast to previous studies, dental neglect was negatively associated with dental anxiety. Additionally, no link was found between body image dissatisfaction and dental neglect. Conclusions: The current study highlights the importance of addressing these factors prior to invasive procedures.
