Comparative Efficacy of Hand Disinfection Potential of Hand Sanitizer and Liquid Soap among Dental Students: A Randomized Controlled Trial

Evaluation of the Efficiency of Hand Hygiene Technique with Hydroalcoholic Solution by Image Color Summarize

Background and Objectives: The HH (hand hygiene) technique is relatively simple. Even so, in practice there are still non-conformities regarding this aspect. Lack of knowledge or lack of compliance can be reasons for non-adherence with HH techniques. In this context, the purpose of this study was to follow the realization of the hand-washing technique with hydroalcoholic solution, applied before and after receiving the HH recommendations. Materials and Methods: A descriptive, cross-sectional study was conducted from May 2022 to June 2022. Students from a second year dental medicine class teaching in French 2021/22 “Grigore T. Popa” University of Medicine and Pharmacy in Iasi were included in the study. The approval of the ethics commission was received: No. 184/05.05.2022. The study was conducted in two stages. In the first stage, HH was performed without any recommendation. In the second stage, the antiseptic hand rubbing technique was presented following the WHO recommendations. The fluorescent Fluo-Add solution, Wood lamp for dermatology (4 × 5.5 W ultraviolet tubes with a wavelength of 360 nm), and photo camera were used. Subjects performed their HH movement before and after receiving instructions according to WHO. Images were initially taken from the backhand and palm and were finally analyzed with Image Color Summarizer. The data were analyzed by the Mann–Whitney U Test, t-test paired samples using IBM-SPSS version 26 (IBM, Armonk, NY, USA), and p ≤ 0.05 was considered statistically significant. Results: After analyzing the images, there were 70 subjects, 45.7% (32) female and 54.33% (38) male. Final average covered area of backhand was 60.89% (±17.17), 28.84:86.11, compared to 52.07% (±17.04), 9:85.23. Final average covered area for palm was 69.91% (±13.5), 31.61:93.41 compared to 59.74% (±16.64), 26.13:92.72. No statistical significance was obtained by gender. Conclusions: The study showed an improvement in hand hygiene technique without highlighting gender differences.

Knowledge and Practice of COVID-19 Infection Control Among Dental Students and Interns: A Cross-Sectional Survey

INTRODUCTION

To assess the knowledge and practice of dental students and interns regarding coronavirus disease (COVID-19) based on academic level and university.

MATERIALS AND METHODS

A cross-sectional survey was carried out among interns and dental students using self-administered, structured questionnaire regarding knowledge and clinical practice with respect to COVID-19 pandemic.

RESULTS

A total of 126 completed questionnaires were received. A majority of the study participants (98.4%) stated they were aware of the COVID-19 infection control policies. Most participants (83.3%) had attended training or lectures about COVID-19. Most of them stated that the N59 mask is the best mask against the disease (81.7%). Significant variations between academic years and genders were revealed regarding the clinical practice. Uncertainty existed regarding quarantining, preprocedural mouth wash, and handwashing versus desensitizing.

CONCLUSION

The level of knowledge of the participants was reasonable. Areas of deficiency in knowledge were observed among junior dental students. Further training in infection control measures and formulation of new guidelines are recommended to increase the knowledge and preparation of dental students regarding COVID-19 in dental settings, as well as reduce the transmission of infection.
