ABSTRACT
A proposta da presente revisão de literatura foi estabelecer as evidências existentes sobre etiologia, sinais e sintomas, métodos de diagnóstico e tratamento de dentes gretados. Segundo a American Association of Endodontists (AAE), o termo dente gretado (DG) foi definido como uma fratura em um plano que quebra a continuidade do esmalte e da dentina, sem separação das partes, geralmente no sentido mesiodistal, passando pela superfície oclusal, podendo envolver uma ou ambas as cristas marginais. Essa fratura, por apresentar profundidade e direção desconhecidas, pode se estender até a polpa e/ou ligamento periodontal, levando a um quadro de pulpite reversível, pulpite irreversível, necrose pulpar ou, até mesmo, evoluir para uma fratura completa. Atualmente, os DGs estão relacionados à terceira maior causa de dentes perdidos, após cárie e doença periodontal. Estudos indicam uma falta de consenso entre profissionais sobre como tratar dentes gretados, uma questão clínica relevante, que precisa ser priorizada e esclarecida. Nesse contexto, essa revisão abordou a etiologia, sinais e sintomas, métodos de diagnósti- co e tratamento de dentes gretados (AU)
The purpose of this literature review is to examine the existing evidence regarding etiology, signs, symptoms, methods of diagnosis, and treatment of cracked teeth. According to the American Association of Endodontists (AAE), the term cracked tooth (CT) is defined as "a fracture in a plane that breaks the continuity of the enamel and dentin, without separation of the parts, usually in the mesiodistal direction, passing through the surface occlusal, which may involve one or both of the marginal ridges." Due to its unknown depth and direction, this fracture can extend to the pulp and periodontal ligament, leading to reversible pulpitis, irreversible pulpitis, pulp necrosis, or even progress to a complete fracture. Currently, cracked teeth are related to the third largest cause of missing teeth, after caries and periodontal disease. Studies indicate a lack of consensus among professionals about treating cracked teeth, a clinically relevant issue that needs to be prioritized and clarified. In this context, this review addressed the etiology, signs and symptoms, diagnostic methods, and treatment of cracked teeth (AU).

OBJECTIVE：To provide reference for improving the equity of medicine in China ，and to provide reference for promoting the full coverage policy for essential medicine. METHODS ：Taking hypertension essential medicines full coverage policy in 4 areas of Taizhou in Zhejiang province as an example ，the electronic health records of patients in baseline year and the first ， second and third years after the implementation of the full coverage policy of hypertension were collected. The catastrophic expenditure of family drugs was used to measure the medicine cost burden ，and the effects of policy on the equity and change of local medicine cost burden were analyz ed by means of concentration index and its decomposition method. RESULTS ：With the increase of the proportion of patients taking free medicine ，the incidence of catastrophic expenditure on household medicines in the high，middle and low income group decreased year by year generally （decreasing from 6.3％，12.0％，16.4％ of baseline year to 4.7％，8.9％，12.4％ at the third year after the implementation of the policy ）；the gap among the three groups was in narrowed trendency. The concentration indexes of the baseline year and the first ，second，third year after the implementation of policy were －0.198，－0.186，－0.181，－0.202，the policy contribution rates of which were 0，－1.335％，－4.507％ and 1.936％；and the policy contribution rates in the change of the yearly concentration index were 20.8％，95.0％ and 57.6％. CONCLUSIONS ：The implementation of the full coverage policy for essential medicines is conducive to improving the equity of the medicine expenditure burden. The effect is affected by the implementation of policies and supporting systems ，but the comprehensive promotion of the equity of medicine requires multi-policy synergy.
ABSTRACT
OBJECTIVE： To evaluate the economics of the full coverage policy for hypoglycemic essential medicines in Taizhou city， and to provide reference for improving medicine accessibility and essential medicine system in China. METHODS： The electronic health records and financial input data of diabetic patients were extracted from different districts and counties of Taizhou city during 2009-2016. In cohort study design， taking the implementation time of each district and county’s policies as the breakpoint， the data recorded annually were processed as annual data， forming the cohort data for 1 year before （baseline year） and 3 years after the implementation of the policies. According to the choice of free medicines after the implementation of the policy， they were divided into policy group and control group. Propensity score matching was used to balance the differences between two groups to get the final sample， and then the economics of the policy was evaluated with the methods of difference-in-differences. The cost and benefit of implementation policy were calculated. RESULTS： Totally 14 744 people of each group were got by propensity score matching. The mean annual financial expenses on free medicine per capita were 263.8 yuan. Compared with baseline year， mean annual medicine expenses per capita reduced by the policy were 649.2 yuan， and mean annual hospitalization expenses per capita were 624.7 yuan. Thus the input-output ratio of the policy was 1 ∶ 4.8. CONCLUSIONS： The implementation of the policy is beneficial to reduce the cost burden of patients and economical. It can be popularized and sustained through scientific design combined with relevant policies.
ABSTRACT
OBJECTIVE： To provide the empirical basis for improving full coverage policy of essential medicines in China and promoting the fairness and accessibility of medicine. METHODS： Taking Taizhou diabetes essential medicines full coverage policy as an example， the electronic health records of diabetic patients in Taizhou city from 2011 to 2017 were collected， and the cost burden of patients was evaluated by whether catastrophic expenditure of family drugs had occurred. The concentration index was used to analyze the fairness of catastrophic expenditure on household medicines， and the effects of various influencing factors on the fairness of local medicine expenditure affordability were evaluated by year-by-year comparing the relevant indexes from baseline year to the third year of policy implementation. RESULTS & CONCLUSIONS： The concentration index of catastrophic expenditure on household medicines is negative from baseline year to the third year of policy implementation， which indicates that catastrophic expenditure on household medicines for diabetic patients in Taizhou mainly occurs in low-income groups. From the result of decomposition of concentration index， among the factors that affect the fairness of catastrophic expenditure on drugs in diabetic families， the contribution rate of “taking free essential medicines” keeps at top five places year by year， and the contribution value is positive， which shows that the implementation of policies is conductive to reducing the unfairness of catastrophic expenditure on household medicines in low-income families. Full coverage policy of essential medicines effectively improves the fairness of medicine expenditure affordability. In addition， scientific and reasonable essential medicines selection mechanism， the guarantee level of the policy， collaboration with multiple factors should be promoted so as to improve the fairness and accessibility of essential medicines.
ABSTRACT
OBJECTIVE： To investigate the effects of full coverage policy for essential hypertension medicines on economic burden of hypertensive patients in Taizhou of Zhejiang Province， and to further provide reference for the practice and promotion of the policy for essential medicines. METHODS： By querying electronic health records database of hypertension patients and statistics of health bureaus in different districts and counties of Taizhou city， the data of electronic health records of hypertension patients were extracted 1 year before and during 3 years after the implementation of full coverage policy for essential medicines in all districts and counties. The patients who had consistently taken free medicines were included in the policy group； the patients who had never taken free medicines were included in the control group. The policy group and control group were matched 1 ∶ 1 by propensity score matching method. Per capita drug cost and per capita hospitalization cost of patients before and after the implementation of full coverage policy for essential medicines were calculated. The input-output ratios of the policy were calculated. RESULTS： During the 3 years after the implementation of the policy， each patient saved 91.3， 272.0 and 464.1 yuan respectively. The hospitalization cost for each patient increased by 65.6 and 46.2 yuan in the first and second year， and decreased by 352.8 yuan in the third year， respectively. A three-year per capita input of policy was 50.0， 147.2 and 278.5 yuan， with input-output ratio of 0.51， 1.28 and 2.25. CONCLUSIONS： The full coverage policy for essential hypertension medicines in Taizhou city demonstrates economic efficiency to some extent， but researches about the impact of policy on disease treatment needed to be conducted. It is necessary for the government departments to invest continuously for a long time and improve the supporting measures so as to make the policy more profitable.
