RESUMEN
Background: COVID-19 remains a major public health threat globally, and has challenged healthcare systems and services including oral health Objective: This study examines the key public health challenges posed by the COVID-19 pandemic in low resource settings. While healthcare services are learning to cope with the COVID-19 pandemic, dental care services, in particular restorative dental practice have been adversely impacted because of the closeness of caregivers to the patient's mouth as well as the generation of aerosols during most restorative procedures. This presents a challenge for low-and-middle-income countries (LMICs) such as Nigeria where weak and poor governance structures characterize healthcare systems in addition to paucity of economic resources. Another challenge in the form of COVID-19 conspiracy theories has threatened to undermine public health efforts designed to control the pandemic. Conclusion: The implementation of optimal guidelines and safety protocols for effective COVID -19 infection prevention and control is a major challenge for restorative dental care practice in low resource settings owing to paucity of key material resources and inappropriate behaviour associated with lingering doubts about COVID-19 reality among the majority of the populace. The Safer Aerosol-Free Emergent Dentistry concept offers a viable practical approach for restorative dental practice in LMICs during and in the post COVID-19 pandemic era. There is a need to deploy all resources, human and material, in the education and enlightenment of the populace regarding the reality of COVID-19.
