Abstract

Background: Coronavirus disease-2019 (COVID-19) has substantially impacted oral health services in Malaysia. The Prime Minister of Malaysia announced the “Transition to Endemic” phase of COVID-19. Although the World Health Organization issued provisional guidelines to address considerations for essential oral health services during the pandemic and endemic phases of COVID-19, there are limited studies on dental professionals’ knowledge, attitudes, and perceptions regarding COVID-19. Purpose: To investigate the attitudes, perceptions, and preparedness of dental professionals in Malaysia during the transition from the pandemic to the endemic phase of COVID-19. Methods: This study was conducted among dental professionals practicing in Malaysia, either in the private or public sector. A cross-sectional online survey of 151 dentists was conducted between December 1, 2022, and January 13, 2023. A questionnaire was disseminated via Google Forms. The data were analyzed using IBM SPSS for Windows, v. 22.0. Descriptive statistics and the chi-square test were used, with p < 0.05 considered significant. Results: The response rate was 100%. The majority of participants displayed a positive attitude toward the transition. Most respondents reported continuing to implement some general standard operating procedures in their dental practices. This study provides insights into the preparedness of dental practitioners in Malaysia for the transition from the COVID-19 pandemic to the endemic phase. Conclusions: The participants demonstrated a positive attitude and mental preparedness for the transition from pandemic to endemic, though some anticipated impacts on clinical practices during the post-lockdown period. This reflects an overall optimistic outlook among dental practitioners during this transition.

Abstract

Introduction: Composite resin is a restorative material that bonds to tooth structure through micromechanical interlocking. Etching removes the smear layer and creates microporosities, enhancing mechanical retention. Although 37% phosphoric acid is the gold standard, it may cause inflammatory cell infiltration. Averrhoa bilimbi L. contains citric, oxalic, and lactic acids, which may serve as a natural alternative etching agent for enamel. This study aimed to analyze the effect of Averrhoa bilimbi L. extract gel as a natural enamel etching agent on the tensile bond strength of composite resin restorations. Methods: This was an in vitro laboratory true experimental study that employed a post-test-only control group design. Twenty-eight extracted human premolars were divided into four groups (n = 7): three experimental groups etched with 2.5%, 5%, and 7.5% Averrhoa bilimbi L. extract gel, and one control group etched with 37% phosphoric acid. After etching, bonding agent and microhybrid composite resin were applied. Tensile bond strength was tested using a Universal Testing Machine, and data were analyzed using the Shapiro–Wilk, Levene’s, and Kruskal–Wallis tests. Results: The highest mean tensile bond strength was observed in the 37% phosphoric acid group (7.56 ± 3.87 MPa), followed by 7.5% (6.71 ± 1.71 MPa), 5% (6.17 ± 1.39 MPa), and 2.5% (6.04 ± 3.01 MPa) Averrhoa bilimbi L. extract groups. The Kruskal-Wallis test showed p=0.874, indicating no statistically significant difference between the groups. Conclusion: Averrhoa bilimbi L. extract gel demonstrated a tensile bond strength comparable to that of 37% phosphoric acid. The extract gel demonstrated promising potential as a natural etching agent; however, further laboratory and clinical studies are required before it can be recommended for clinical application.

Abstract

Introduction: Oral health is an essential component of overall quality of life; however, the prevalence of dental caries in Indonesia remains high, particularly among elementary school children, partly due to inadequate toothbrushing skills. Various digital educational innovations, including mobile health applications and augmented reality (AR)-based interventions, have demonstrated positive effects on oral health education and behavioral change. Nevertheless, evidence regarding the effectiveness of the HI Bogi AR-based application, especially in improving children’s toothbrushing skills, remains limited. Therefore, this study aimed to analyze the effectiveness of the augmented reality-based HI Bogi application in improving toothbrushing skills among elementary school children using a quasi-experimental design. Methods: This study employed a quasi-experimental design with a one-group pre- and post-test design. A total of 170 elementary school students aged 9–12 years from Cimahi City were recruited using simple random sampling. The intervention involved the use of the HI Bogi AR-based application for 21 days. The research instrument was an observational questionnaire comprising 13 indicators of toothbrushing skills. Data were analyzed using a paired t-test for normally distributed data and the Wilcoxon signed-rank test for non-normal data. Results: Toothbrushing skills improved significantly following the intervention (Wilcoxon signed-rank test: Z = −15.192, p < 0.001). The mean toothbrushing skill score increased from 4.40 ± 3.77 at baseline to 12.62 ± 0.71 after the intervention, representing an average improvement of 8.22 points. These findings indicate that the HI Bogi AR application substantially improved children’s toothbrushing skills. Conclusion: The HI Bogi application integrated with augmented reality (AR) proved effective in improving proper toothbrushing skills among children aged 9–12 years in Cimahi City. This innovation has the potential to serve as an alternative, promotive, and preventive oral health education tool to support school-based oral health programs.
