新癀片用于口腔种植牙术后肿胀疼痛中的治疗效果观察

目的：探析口腔种植牙术后肿胀疼痛采取新癀片进行治疗的效果及对炎性因子的影响。方法：选取2015年1月至2019年12月北京中医药大学东直门医院收治的口腔种植牙术后肿胀疼痛患者300例作为研究对象，按照随机数字表法随机分为对照组和观察组，每组150例，对照组采用红霉素治疗，观察组采用新癀片联合红霉素治疗，比较2组患者术后肿胀和术后疼痛持续时间、牙槽骨吸收量、种植牙功能、种植体唇侧骨厚度、周围边缘骨吸收量、炎性反应因子水平、治疗优良率等指标。结果：与对照组比较，观察组术后肿胀持续时间、术后疼痛持续时间明显较短（P<0.05）；观察组种植牙功能评分等明显高于对照组（P<0.05）；观察组种植体唇侧骨厚度、周围边缘骨吸收量与对照组比较有明显差别（P<0.05）；观察组CPR、IL-6、PCT等炎性反应因子水平明显较低（P<0.05）；观察组治疗总有效率明显高于对照组（P<0.05）。结论：口腔种植牙术后肿胀疼痛应用新癀片进行治疗，能获得较为理想的效果，改善炎性反应因子水平，有着极大的推广价值。     

What Is Really Needed to Provide Effective,Person-Centered Care for Behavioral Expressions of Dementia? Guidance from The Alzheimer's Association Dementia Care Provider Roundtable

In April, 2019, the Alzheimer's Association Dementia Care Provider Roundtable convened to discuss common challenges faced when implementing person-centered, non-pharmacological practices in long-term care and other settings that provide care and programs for persons living with dementia, and to develop relevant, specific guidance from the perspective of administrative leaders from 23 long-term and community-based care provider organizations (representing home, community-based, and residential care). Guidance related to 5 practice areas emerged from the facilitated discussion: having a foundational person-centered culture, conceptualizing behaviors as expressions and focusing on behavioral support, identifying antecedents and placing person-centeredness before protocols, modifying training to promote person-centered culture, and valuing implementation flexibility. In developing the practice guidance, a related list of priority areas for research and policy were also identified.     

鄂托克前旗马场井村改水降氟15年病情防治效果分析

目的：了解改水降氟后地氟病的防治效果。方法：水氟，尿氟测定均为电极法，氟斑牙诊断为Dean‘s法。结果：该村自1985年改饮低氟水，水氟含量由改水前的6.05mg/L降至改水后的0.48mg/L。改水后未出现新的氟骨症患者，8-12岁儿童氟斑牙患病率呈逐年下降趋势，改水后7-15年间氟斑牙病率均已稳定，表明病情得到有效控制，且达到稳定控制状态，结论：坚持长年饮用低氟水，地方性氟中毒就能得到有效控制。     

颞下颌关节紊乱综合征(?)与龋因素的流行病学研究

目的:为探讨(?)因素、龋因素与颞下颌关节紊乱综合征(TMJDS)致病关系和作用机理。方法:以东北电力学院入学新生为研究对象。采用TMJDS、龋诊断标准和安氏分类等方法,对1065名大学生进行流行病学研究。结果:正常(?)TMJDS阳性率为6.81%,异常(?)TMJDS阳性率为48.32%,具有显著差异性。无龋者TMJDS阳性率为23.72%,龋病者TMJDS阳性率为39.58%,具有显著差异性。结论:异常(?)、龋病是TMJDS的致病因素之一。     

Risk behaviors and its association with caries activity and dental caries in Japanese children

The aim of this study was to assess risk behaviors and its association with caries activity and dental caries in Japanese children. The subjects were 392 young Japanese children who underwent dental health check-up at 18, 30 and 42 months of age. Oral examinations, Cariostat tests and dental health questionnaires were carried out at each time. The caries prevalence of children was 1.5% at 18 months, 9.9% at 30 months and 28.1% at 42 months. Caries activity based on the Cariostat scores of children was correlated with caries status (caries-free/carious) at 42 months. In children with caries during each examination period at 42 months, eating snacks while playing was ranked as the most important behavioral risk (P < 0.001), followed by breast-feeding (P < 0.01), non setting of time for snacks (P < 0.05) and frequency of snacks (P < 0.05) at 18 months old; non brushing by mother (P < 0.05) and eating snacks while playing (P < 0.05) were ranked highest at 30 months old. In addition, eating snacks while playing (P < 0.001) at 42 months old was the only a significant factor for children with caries. Caries activity and risk behaviors were associated with caries experience at different age periods of childhood.     

固定桥桥体龈底形态对接触区黏膜微生态影响的研究

目的探讨烤瓷桥桥体龈端不同形态设计对牙槽嵴顶黏膜微生态的影响。方法对60例磨牙烤瓷修复的患者采用常规细菌培养和计算机鉴定的方法进行检测。结果桥体龈端接触区细菌附着量和种类与牙体预备前相比,均有增多。其中,改良鞍式和改良盖嵴式桥体龈端接触区细菌附着量和细菌种类变化的差异有统计学意义(P<0.05);而舟底式桥体龈端接触区细菌附着数量和种类的变化,均无统计学意义(P>0.05)。戴用3个月后,各组链球菌和奈瑟菌的组成比例变化与牙体预备前相比,差异有统计学意义(P<0.05);其余各类细菌组成比例的变化无统计学意义(P>0.05)。结论从对桥体底黏膜微生态的影响考虑,烤瓷桥舟底式桥体优于改良鞍式和改良盖嵴式桥体,是值得临床推广应用的磨牙桥体设计。
