ABSTRACT
The gradual relaxation of COVID-19 restrictions in China has increased the risk of imported dengue fever cases and may further prompt the outbreak. Systematic assessment of disease burden is crucial to improving prevention and control strategies， and resource allocation of dengue fever in China. After reviewing the definition， classification of disease burden， epidemiological evaluation methods such as potential years of life lost （PYLL） and disability adjusted of life years （DALY）， as well as economic evaluation methods such as step-by-step model method and human capital method， this article systematically summarizes the application of mixed models and catalytic models in quantifying the disease burden of latent dengue infected individuals， as well as the current research status and limitations of dengue disease burden in China， proposing suggestions for future assessment research on disease burden of dengue.
ABSTRACT
To analyze the global burden of periodontal disease and its relation with socioeconomic development. Data of global disability-adjusted life year (DALY) due to periodontal disease and human development index (HDI) from 1990 to 2019 were obtained from Global Health Data Exchange (GHDx) and human development reports. The trend of the global burden of periodontal disease from 1990 to 2019 was described. The correlation between age-standardized DALY rates and HDI were examined in 2019, and between-country periodontal disease burden inequality from 1990 to 2019 was measured using health-related Gini coefficients and concentration indexes. From 1990 to 2019, the global DALY rate due to periodontal disease increased from 78.63 to 85.48, and the epidemiological burden did not increase significantly. Statistical differences were found across different HDI categories for age-standardized DALY rates of periodontal disease ( 44.315, <0.01) in 2019. Linear regression analysis also revealed a negative correlation between age-standardized DALY rate of periodontal disease and HDI ( = -0.417, <0.01) . Gini coefficients decreased from 0.361 to 0.281 and concentration indexes fell from 0.0339 to -0.0538 between 1990 and 2019. The global burden of periodontal disease did not increase between 1990 and 2019, though the socioeconomic-associated inequality still existed. The burden of periodontal disease was more concentrated in less developed countries, and the socioeconomic-associated inequality has increased since 2000.

At present, it has been regarded that oral disease was one of the most prevalent problems for people's general health around the world. Oral disease burden study focuses on the pressure and effect of oral diseases to the whole social economy and people's health. Oral disease burden, as a public health problem, needs to be attached importance in China and foreign countries. By means of retrieving the literature, this review article summarizes the progress of domestic and oversea studies on oral disease burden, analyses the epidemiological burden through the indicators such as the prevalence rate, decayed missing and filled teeth, disability adjusted life years, disability weights, and illustrates the economic burden of oral diseases by using part of the data. Results shows that the oral disease burden is obvious in most countries and regions both in China and foreign countries. The study of oral disease burden in China has not been well developed. Giving priority to dental caries, periodontal disease and tooth loss, the prevalence of oral diseases in China is high. The rate of seeking dental treatments is low and the proportion of self-supporting treatments is high. In general, the epidemiological and economic burden of oral diseases is heavier in China than that in the rest of the world.
