    This overview was conducted to highlight the importance of adequate oral hygiene for patients severely affected by coronavirus disease 2019 (COVID-19) due to infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). These are patients who were admitted to the intensive care unit (ICU) to receive oxygen through mechanical ventilation due to severe pneumonia as a complication of COVID-19. Various dental plaque removal methods for ventilated patients were discussed with regard to their efficacy. The use of chemical agents was also considered to determine which one might be proposed as the best choice. Also, oral care programs or systems that can be implemented by ICU nurses or staff in the case of these ventilated patients were suggested based on evidence from the literature. These interventions aim to reduce microbial load in dental plaque/biofilm in the oropharynx as well as the aspiration of the contaminated saliva in order to prevent the transmission of the dental plaque bacteria to the lungs or other distant organs, and reduce the mortality rate.

    BACKGROUND: Athletes with disabilities may be at an even greater risk of orofacial trauma than their counterparts, and the risk may vary depending on the type of sports. This study aimed to assess the incidence of sports-related dental injuries and oral health status among Malaysian para-athletes.

    METHODS: A questionnaire survey was conducted to assess self-reported dental injuries and knowledge of their management. An intraoral examination was performed using the decayed, missing, and filled teeth (DMFT) index following the World Health Organization guidelines.

    RESULTS: A total of 61 para-athletes (men = 90.16%, n = 55; women = 9.84%, n = 6) from different sports categories with different disabilities randomly participated in this study. The incidence of self-reported dental injuries was 18.0% (n = 11), with the most common injury being crown tooth fracture (72.7%) and lip laceration (63.6%). However, the majority of the athletes (70.5%, n = 43) did nothing after experiencing dental trauma, and 82.0% (n = 50) were unaware of the immediate management of dental trauma. Based on the intraoral examination, only 9.8% (n = 6) of the athletes had perfectly sound teeth. The mean total DMFT index was 3.49 ± 2.371, while the mean DMFT index for decayed, missing, and filled teeth was 1.28 ± 1.293, 0.74 ± 0.705, and 1.48 ± 1.120, respectively. The mean DMFT index for decayed, missing, and filled teeth and total DMFT index significantly differed among the types of disabilities (P  .05).

    CONCLUSION: The most commonly reported injuries among para-athletes are crown tooth fractures and lip lacerations. The total DMFT index among para-athletes is moderate, emphasising the need for improvements.

    This study aimed to investigate the efficacy and durability of bioactive glass-based dental resin infiltrants. Resin infiltrants were formulated by combining photoinitiated dimethacrylate monomers with three variations of bioactive glass: 45S5 Bioglass (RIS), boron-substituted (RIB), fluoride-substituted (RIF), and pure resins (PR), whereby TOOTH group (TH) and ICON (CN) served as commercial control groups. Teeth samples were prepared, and experimental and control infiltrants were applied on demineralized human-extracted teeth. All the samples were subjected to immersion in artificial saliva and pH cycling for 30 days. The samples from another group underwent tooth brushing simulation for 9600 cycles. Following artificial saliva immersion, the samples' hardness values showed that RIB had the highest values (318.44 ± 3.83) while PR (212.52 ± 9.02) had the lowest values. After immersing into the pH cycling solution, the RIF showed the highest hardness (286.86 ± 5.11), while the lowest values for the CN (143.76 ± 3.50). After the tooth brushing simulation, the teeth samples with RIB showed maximum microhardness values (312.06 ± 16.30) and the weakest for the TH (189.60 ± 6.43). The commercial and experimental enamel resin infiltrants showed almost similar results overall, with RIB demonstrating better microhardness and comparable surface roughness. In contrast, RIF proved more resistant to pH cycling, exhibited higher microhardness, and performed better in surface roughness analysis. These findings suggest that resin infiltrant materials, especially RIF, have promising potential for effectively and esthetically managing white spot lesions.
