 The study examined global trends in age standardized incidents and disability adjusted life years of oral disorders from 1990 to 2019 by region and social demographic index, finding that the global age standardized incidents rate increased slightly while regional age standardized Dali rates decreased in highest DI regions, but increased in lowest DI regions. The study highlights the need for controlling the increase in Dali and disease burden associated with oral disorders in low, low-middle and mid-less DI regions, particularly in South Asia and India.
