目的应用一种小型分光光度计对上前牙区种植支持式氧化锆全瓷修复与贵金属金瓷修复的牙冠颜色进行比较,为临床选择修复材料提供参考依据。方法纳入18例(男7例,女11例)行口腔种植修复后复查患者的上前牙区种植支持式单冠29颗进行研究,其中氧化锆全瓷修复单冠11颗,贵金属金瓷修复单冠18颗。采用小型反射型分光光度计型比色仪SpectroShadeTM采集图片并输入计算机,应用相关软件测量每个种植牙冠体1/3与对照天然牙的CIE L﹡a﹡b﹡颜色差异。应用统计学软件SPSS 17.0进行统计分析。结果氧化锆全瓷修复和贵金属金瓷修复的牙冠明度均高于天然牙,全瓷修复引起的明度差异(4.5±3.2)大于金瓷修复引起的明度差异(1.0±2.6),具有统计学意义(P=0.004);色相差异和饱和度差异均无统计学意义。全瓷修复和金瓷修复与天然牙的颜色差异(7.0±2.8和4.0±1.9)均高于人眼的分辨阈值(3.7),且前者差异大于后者,具有统计学意义(P=0.002)。氧化锆全瓷和贵金属金瓷两种修复方式的临床主观评分无统计学差异(P=0.977)。上前牙天然牙色由前向后明度渐低,色相变红黄。结论就本试验所选用的修复材料而言,分光光度计测量显示氧化锆全瓷修复与天然牙的牙冠颜色差异大于贵金属金瓷修复与天然牙的颜色差异,但两种修复方式的临床效果无明显区别。

目的:应用一种新的小型分光光度计,对上前牙种植支持式全瓷修复与金瓷修复的边缘牙龈的龈色改变进行比较,为临床选择修复材料提供依据。方法:选择口腔种植修复后复查患者18例(男7例,女11例),共计上前牙区种植支持式单冠29例(全瓷修复11例,钛合金基台金瓷修复9例,金合金基台金瓷修复9例)。通过仪器采集图片并输入计算机,应用相关软件测量种植冠颈部边缘牙龈与对照天然牙牙龈的CIELab颜色差异。另由医师对冠缘龈色改变进行临床牙龈变色指数(GDS)评价。采用SPSS 17.0软件包对数据进行统计学分析。结果:分光光度计测量结果显示,上前牙种植支持式全瓷修复组(3.4±1.8)与金瓷修复组(4.9±3.4)引起的龈色改变无统计学差异。其中,全瓷修复与钛基台金瓷修复方式(3.5±2.5)之间的差异和钛基台金瓷修复与金基台金瓷修复方式(6.3±3.8)之间的差异均无显著性,但全瓷与金基台金瓷修复方式之间的差异具有统计学意义(P=0.037)。此外,全瓷组与金瓷组间的主观牙龈变色指数(GDS)无统计学差异,临床牙龈变色指数与分光光度计测得的牙龈变色值之间具有相关性(rs=0.426,P=0.021)。天然中切牙、侧切牙和尖牙在牙龈色彩的明度上无显著差异,但在红绿色轴饱和度和黄蓝色轴饱和度方面,尖牙高于中切牙和侧切牙。结论:全瓷组与金瓷组的龈色改变在分光光度计评价和临床评价上均无显著差异,但高金合金基台联合金瓷冠修复方式引起的种植冠边缘牙龈色差显著大于全瓷修复方式。

目的探讨上颌中切牙进行种植支持式单冠修复后,采用牙龈乳头指数对种植牙周进行美学评价的可信度与有效性。方法纳入上颌中切牙种植支持式单冠修复后的患者25例。由两名观察者分别对每例患者的3个牙龈乳头位点进行牙龈乳头指数评分(PIS),计算两观察者的观察者自身前后对照一致性百分比和Cohen'sκ值,及观察者间对照一致性百分比和Cohen'sκ值,验证PIS指数应用的可信度。此外,在图片上测得每个位点的牙龈乳头实际长度(ST),得出该位点的牙龈乳头丰满度(PP)。用Spearman相关系数检验PIS与PP的相关性,验证PIS指数在种植支持式单冠修复后牙周组织美学效果评价中的有效性。结果两名观察者在三位点总计的可重复性均超过70%,Cohen'sκ值均达到了"较好"的程度。κ值显示三位点总计的观察者间对照一致性均达到"中等"水平。统计显示PIS指数与牙龈乳头丰满度(PP)有显著相关性(rs=0.567,P=0.000)。结论 PIS这一指数的可行性、可信度和有效性较高,可作为单牙种植修复后牙周软组织美学效果评价中的重要评价指标。

Group discussion teaching technique for small groups and encouragement of critical but constructive and creative thinking for finding new and efficient solutions can lead to provision of better health and medical services that is defined in clinical setting, as the clinical psychology finds a way for curing and education. The present study was conducted with the aim to compare the effects of creative group teaching and educational booklet on interpersonal skills of midwives in a clinical setting. The present study was conducted on 97 midwifery graduates working in hospitals in Kerman Province, in two groups of educational booklet (49 midwives) and educational workshop (48 midwives) who participated in a 3-day creative teaching workshop in summer 2015. Creative problem-solving teaching intervention group was taught through educational workshop method, including small group and team working, group discussion and mini lectures. Midwifery 1 intervention group was provided with an educational booklet validated by professors of Nursing and Midwifery School for independent and individual study by midwives working in Kerman Province hospitals. The two groups were matched in terms of personal details. Hospitals were randomly selected, and midwives were selected by quota sampling. Interpersonal communication skills of both groups were assessed before and after intervention, and two months later using Interpersonal Communication Skills Test. The results obtained were analyzed in SPSS-16 using descriptive statistics, including frequency and percentage, mean and standard deviation, and inferential statistics including U-Mann-Whitney, paired t, independent t, repeated measures ANOVA tests at significance level of P P P P P < 0.001). Both teaching methods improved midwives’ interpersonal communication skills. Therefore, standardized educational booklets which produce cost-effective similar results are recommended.
