Abstract

This paper discusses the development of a wheelchair recliner for dental treatment that can accommodate users of different body mass index (BMI) categories. The study aims to identify the ergonomic angle for a dental chair, design a wheelchair recliner with appropriate reclining angles, and analyse its performance using simulations and user testing with different BMI subjects. The simulation of the wheelchair recliner was performed using the Motion of Inspiration (MOI) 3D to analyse the withstanding load, including the wheelchair load and subject load (2000 N). The displacement and safety factor for the long pin of the recliner was also analysed. The study's main findings indicate that the developed wheelchair recliner can withstand a load of 2000N, which includes both the wheelchair load and the subject's load. The study tested the wheelchair recliner with three reclined angles: 40º, 45º, and 50º. It found that regardless of their BMI category, all subjects were comfortable using the wheelchair recliner at these angles during dental treatment. Overall, the study suggests that the developed wheelchair recliner has the potential to provide comfort to wheelchair users with various BMI categories during dental treatment, eliminating the need for uncomfortable transfers from the wheelchair to the dental chair.

Abstract

Background: There is a limited number of studies on the prevalence of dental anxiety among the general population in Malaysia and its association with mental health. Purpose: This study aimed to assess the prevalence of dental anxiety and its association with mental health. Methods: This cross-sectional study was conducted among 474 adults attending a public hospital in Kuantan, Malaysia. Participants were required to answer validated, self-administered questionnaires that used the Modified Dental Anxiety Scale (MDAS) and Depression Anxiety and Stress Scale (DASS). Data were analyzed using chi-square and Mann-Whitney tests. Multiple logistic regression was used to determine the relationship between dental anxiety and other variables. Results: A total of 461 respondents completed the questionnaire, with a response rate of 97.3%. The prevalence of dental anxiety among respondents was very high (93.1%). We found that females were 2.3 times more likely to have dental anxiety than males. Meanwhile, an increase in age by one year reduced the likelihood of having dental anxiety by 3%. However, no significant association was found between dental anxiety and mental health. Conclusion: The majority of adults in Kuantan were found to have dental anxiety. Female and younger patients were more likely to have dental anxiety. Our study failed to find any association between dental anxiety and mental health.
