摘要
目的:评价家用过氧化脲凝胶对氟斑牙着色斑漂白的临床效果。方法:将24例氟斑牙患者的108颗着色氟斑牙,根据着色区着色深浅分为轻、中、重度3组,用过氧化脲凝胶进行家庭漂白。在治疗前、治疗结束时及治疗结束1年后,采用CMYK色值表对氟斑牙着色斑进行比色,记录漂白前、后的色阶变化及疗程,计算漂白有效率并评价疗效稳定性;用数字化疼痛评判法记录受试者术中牙的敏感度。采用SPSS13.0软件包对结果进行χ2检验。结果:(1)轻度氟斑牙着色斑脱色效果显著,1个疗程内漂白有效率达100%;中、重度氟斑牙着色斑脱色效果稍差,有效率分别为94.29%和86.21%,3组间无统计学差异(P>0.05)。(2)治疗结束1年后复查,3组漂白有效率与治疗结束时比较均无统计学差异(P>0.05)。(3)用药时,部分患者有不同程度的牙酸痛症状,敏感率为56.52%,停止用药2~3h后,敏感症状消失。结论:家用过氧化脲凝胶治疗氟斑牙着色斑效果显著,具有一定的安全性和稳定性。
PURPOSE: To evaluate the clinical efficacy of carbarnide peroxide in-home tooth whitening for removal of stains caused by dental fluorosis. METHODS: One hundred and eight teeth, from 24 patients with diffuse opacities on the enamel surfaces due to effects of dental fluorosis, were assigned into mild, medium and heavy groups, and treated with carbarnide peroxide in-home tooth whitening. Before, immediately after bleaching and one year later, CMYK shade guide was used to record the change of color. Bleaching efficacy and course of treatment were calculated, and lightening stability was evaluated. The sensitivity of teeth was recorded during the treatment by Visual analogue scale (VAS).The results were analyzed with SPSS13.0 software package for χ^2 text. RESULTS: (1)Mild group had 100% decoloring efficacy after one course. The decoloring efficacy in medium and heavy groups was 94.29% and 86.21%. There was no significant difference among three groups(P〉0.05).(2)There was no significant difference on the treatment efficacy between the time of treatment completion and after one year in all three groups(P〉0.05).(3) The tooth sensitivity appeared during the treatment and disappeared in 2 to 3 hours after divorced from medicine. The sensitive rate was 56.52%. CONCLUSION: The bleaching efficacy of carbarnide peroxide in-home tooth whitening on dental fluorosis’s stains is good, safe and can maintain a period of time.
