A model describing the relationship between self-reported quality of restorative dentistry and dentist characteristics for 119 Montana general dentists is presented. The best predictors formed a significant model explaining 22% of the variance of the quality measure. Results are contrasted with a previous estimation of the model for 102 Washington general practitioners. Evidence for the external validity of the model is presented. 相似文献

目的:研究、比较不同剂型玻璃离子水门汀的溶解性和表面微观形态改变,为临床使用提供依据.方法:将3M树脂加强型玻璃离子水门汀(水粉剂型)、GC玻璃离子水门汀(水粉剂型)及GC玻璃离子水门汀(双糊剂型)分别在人工唾液中浸泡30 d,冷热循环15000次,烘干测重,比较前后质量变化,计算溶解率,并用扫描电镜观察表面微观改变.结果:不同剂型的玻璃离子水门汀溶解率由高到低分别为3M树脂加强型玻璃离子水门汀(水粉剂型)、GC玻璃离子水门汀(水粉剂型)、GC玻璃离子水门汀(双糊剂型).3种玻璃离子水门汀经浸泡溶解后,SEM扫描表面微观形态可观察到GE玻璃离子水门汀(双糊剂型)表面形态改变较少,其他2组玻璃离子水门汀表面微观改变较多.结论:双糊剂型玻璃离子水门汀理化性能及溶解率均低于传统水粉剂型,是未来临床修复治疗的的良好选择. 相似文献

A study was carried out in Sancti Spiritus Province in the 1984-1986 period about the results of the treatment of lip cancer. Male patients were the most affected by lip cancer (CIE 8-140) in our series. The place of the tumor was predominantly the lower lip (p less than or equal to 0.001). Surgical treatment was used in 96.8% of the cases and the cuneiform (wedge-shaped) exeresis was the most commonly used method in the early stages of the disease (T1 y T2). Casta?ón keloplasty was the reconstructive procedure used in 18.7% of the patients. Local sepsis was present in 31.2% of the patients undergoing surgery, occurring most frequently in upper lip tumors. 相似文献

口底癌34例临床分析 总被引:1,自引:0,他引:1
目的探讨口底癌的临床特性、治疗方法及预后。方法对我院自1992—2002年住院治疗的34例口底癌患者进行回顾性分析。结果34例口底癌患者中,男28例(82.4%),女6例(17.6%),男女比为4.7∶1,平均发病年龄58岁。发病部位:前口底22例(64.7%),后口底12例(35.3%)。淋巴结转移率41.2%。单纯手术组、化疗加手术组、放疗加手术组、化疗加手术加放疗组的5年生存率分别为45.5%、60.0%、50.0%、62.5%。结论口底癌以中老年患者好发,男性居多。易发生淋巴结转移,综合疗法疗效较好。 相似文献

目的:探讨平阳霉素损伤血管内皮细胞的机制,为临床应用提供组织学依据。方法:选用成年Wistar大白鼠42只(其中6只为正常对照),经肠系膜静脉分别注入平骒霉素(24只)或鱼肝油酸钠(12只)后,分别于注药后0.5,1,2,4,8,24h,切取肝脏组织,通过酶组化染色法测定肝窦内皮细胞的5’-核苷酸酶,肝细胞的琥珀酸脱氢酶(SDH)及乳酸脱氢酶(LDH)活性,结果:注入药液后,肝窦内皮细胞的5’-核苷酸酶,肝细胞的SDH和LDH活性随时间逐渐下降,其中平阳霉素组下降较轻微,结论:平阳霉素和鱼肝油酸钠都可对血管内皮细胞产生损伤,损伤的性质一样,均为非特异性,但平阳霉素损伤程度轻微,而鱼肝油酸钠严重。 相似文献

大量的临床随机试验结果明确地证实了热疗联合化疗已成为癌症治疗的新的有效方法。热疗联合化疗治疗恶性肿瘤,其效果不仅仅是肿瘤细胞的热损伤和化疗引起的损伤作用之和,同时两者之间还有很好的协同作用,即热疗对化疗具有明确的增敏作用,达到提高化疗疗效的目的。本文就肿瘤热化疗的临床应用和基础研究近况作一综述。 相似文献
