Comparison of Clinical Effects of Au-Pt Based and Ni-Cr Based Porcelain Crowns

Objective To compare the long-term clinical effects of two kinds of crowns and bridges made of porcelain fused to Au-Pt alloy and Ni-Cr alloy. Methods A total of 131 teeth (64 patients) were rehabilitated using porcelain-fused-to-metal crowns, among which 59 were rehabilitated with Au-Pt alloy metal ceramic crown and 72 with Ni-Cr alloy metal ceramic crown. The porcelain fracture, shade, marginal adaptation, gingival discoloration, and gingival status after finishing restoration and 36 months of follow-up were evaluated. Results After 36 months of restoration, porcelain fused to Au-Pt alloy crown showed better clinical effects than porcelain fused to Ni-Cr alloy crown in shade, marginal adaptation, gingival discoloration, as well as gingival status (all P<0.05). Conclusion The Au-Pt alloy ceramic crown is superior to Ni-Cr alloy ceramic crown in long-term clinical effects.

基于交互分析模式的同伴支持模式对青年乙肝患者疾病认知、被歧视心理及自我管理能力的影响

背景本研究以交互分析模式为理论框架,对青年乙肝患者展开同伴支持,以期为提高青年乙肝患者的疾病认知度,缓解被歧视心理,减轻自我感受负担,增强自我管理能力,从而使其保持乐观心理,积极面对生活、遵医科学治疗.目的分析基于交互分析模式的同伴支持模式对青年乙肝患者疾病认知、被歧视心理及自我管理能力的影响,以期为临床感染性疾病的护理工作拓展新思路.方法选取我院2019-01/2020-10感染科青年乙肝患者98例作为研究对象,按入院建档奇偶排序,以1:1配对原则分组,各49例,对照组采取常规护理,于此基础上观察组采取基于交互分析模式的同伴支持模式.比较分析两组干预前后疾病认知、自我感受负担(self-perceived burden scale,SPBS)、被歧视心理及自我管理能力(adult health self-management skill rating scale,AHSMSRS).结果干预后观察组疾病认知度各维度评分均高于对照组(P<0.05);干预后观察组被歧视心理各维度评分均低于对照组(P<0.05);干预后观察组SPBS各维度评分均低于对照组(P<0.05);干预后观察组自我管理能力各项评分均高于对照组(P<0.05).结论在青年乙肝患者管理工作中,基于交互分析模式的同伴支持模式有助于提高患者疾病认知度,减轻心理负担,纠正被歧视心理,同时可增强患者自我管理能力,这对病情控制具有积极作用.
