Introduction: During the Coronavirus Disease-2019 (COVID-19) pandemic, the world has experienced many changes, including increased computer and internet usage. Spending more time on computers can lead to the development of various postural problems, resulting in pain and inefficiency in the workplace. Aim: To assess the knowledge of computer ergonomics among third and final year Bachelor of Dental Surgery (BDS) students at VSPM's dental college in Nagpur, Maharashtra, India. Materials and Methods: This cross-sectional, questionnairebased study was conducted on third and final year students between November 2020 and February 2021 in the Department of Oral Medicine and Radiology at VSPMDCRC, Nagpur, Maharashtra, India. Ethical clearance was obtained from the Institutional Ethical Committee (IEC/VSPMDCRC/15/2020). A self-administered questionnaire, formulated and validated by independent subject experts, was used. A total of 216 students were included in the study over a two-month period. Informed consent was obtained from the students. The questionnaire consisted of 34 questions on computer usage and knowledge of ergonomics, and the responses were recorded. Descriptive statistics were performed using Statistical Packages for Social Sciences (SPSS) version 20.0 for Windows. Quantitative data were expressed as mean and standard deviation. The association between categorical variables was checked using the Chi-square test, with a significance level set at 5%. Results: The mean age of the students was 22.20 years total of 216 students, including 158 females and 58 males, were included in the study. The results showed that 20.37% of third year students (44/96) and 31.48% of final year students (68/96) were aware of the term "ergonomics". The majority of students were unaware of the principles of ergonomics. However, 169 (78.2%) students knew the correct position of the head and neck while using a computer. Additionally, 164 (75%) students were aware of the need for lower back support, 167 (77.3%) were aware of the placement of input devices, and 174 (80.6%) were aware of the alignment of devices. Moreover, 168 (77.8%) subject knew that the monitor and working surface should be glare-free, and 120 (55.6%) were aware that a sloped desk surface is required for reading or writing. Furthermore, 157 (72.7%) subjects used a headset or speakerphone while writing, typing, or talking on the phone, and 164 (75.9%) subjects took regular eye breaks. Conclusion: The present study highlights a lack of practical knowledge and application of ergonomics among the participants. There is a need to prioritise creating awareness and developing healthy ergonomics practices among dental students through Continuing Dental Education programs (CDE). The authors also recommend that the curriculum for healthcare courses should incorporate healthy ergonomics practices as a part of the curriculum. [ABSTRACT FROM AUTHOR] |
