Based on the observed data of groundwater level and chloride ion concentration, groundwater quality in the next 6 years in Zhoushan area is predicted and analyzed by using groundwater numerical simulation software GMS. According to the comparison of observed groundwater level and simulated groundwater level at the end time, it is found that the whole water level in the filling area has the small fluctuation, which is within the range of 1 m. And the highest concentration of chloride ion is in the eastern coastal area. The prediction results indicate that there is no obvious trend of sea water with high chloride ion concentration to land. Under the condition of the current groundwater utilization, the groundwater level in Donggang sea area of Zhoushan is stable, and the chloride ion concentration has a slight decrease trend.展开更多
目的研究不同根管冲洗方案对不可复性牙髓炎根管治疗术后患者疼痛及预后的影响。方法选取2019年1月-2022年3月万载县人民医院收治的72例不可复性牙髓炎患者,按照随机数字表法分为对照组(36例)与观察组(36例)。两组均给予根管治疗,对照...目的研究不同根管冲洗方案对不可复性牙髓炎根管治疗术后患者疼痛及预后的影响。方法选取2019年1月-2022年3月万载县人民医院收治的72例不可复性牙髓炎患者,按照随机数字表法分为对照组(36例)与观察组(36例)。两组均给予根管治疗,对照组应用注射根管冲洗方案,观察组则应用超声根管冲洗方案,比较两组根管充填质量(根充致密性、侧支根管充填率)、牙周指数[菌斑指数(PLI)、探诊出血指数(BI)、牙龈指数(GI)]、疼痛视觉模拟评分(VAS)、口腔健康程度量表(OHIP-14)评分、并发症发生率。结果观察组根充致密性优于对照组,侧支根管充填率高于对照组(P<0.05);两组术后3个月PLI、BI、GI均小于术后即刻,且观察组小于对照组(P<0.05);两组术后24 h VAS评分低于术后6 h,且观察组低于对照组(P<0.05);两组术后3个月OHIP-14评分低于术后1周,且观察组低于对照组(P<0.05);观察组并发症发生率为8.33%,低于对照组的27.78%(P<0.05)。结论超声根管冲洗方案与注射根管冲洗方案在不可复性牙髓炎根管治疗术中均具有确切应用效果,前者可改善根管充填质量,且术后疼痛轻、并发症少,对患者口腔健康具有积极改善作用,其效果优于注射根管冲洗方案。展开更多
