■应用氟化银二胺后,龋齿病变的变色降低了患者的接受度,并限制了其广泛用于龋齿阻止。
■评估2种新型氟化银(AgF)产品的病变和牙齿颜色变化及其与龋齿活动(临床视觉触觉评分)和细菌载量(使用激光荧光与DIAGNOdent)的关系。
■采用了分口设计,在有特殊需要的成年人中,在同一足弓中匹配的光滑表面龋齿病变,随机接受AgF/碘化钾(KI)治疗1分钟(RivaStarAqua,SDI)和AgF/氟化亚锡(SnF2)(龋齿状态披露溶液;Whiteley)。在基线拍摄的标准化图像,术后立即,并在3个月时进行数字图像分析,以计算delta-E并跟踪龋齿病变的光度变化。
■研究招募了12名参与者。总共包括56颗牙齿(28对)。与相邻的非龋齿天然牙齿结构相比,治疗后的病变明显更大的变化,治疗后立即和3个月时(P<0.0001)。颜色变化和龋齿活动不受牙齿类型的影响,牙齿位置,斑块状态,唾液状态,或特殊需要条件。AgF/SnF2在使用时立即导致短暂变暗,而AgF/KI导致立即形成黄色沉积物(碘化银)。两种产品均在3个月时导致治疗的病变明显变黑(P=0.0009;P=0.0361),它们之间没有差异(P=0.506)。应用AgF后,响应性病变立即显示更大,更明显的颜色变化(P=0.002;P=0.024)。
■两种AgF产品对该患者人群的龋齿阻止均非常有效。尽管在应用时治疗病变的外观有微小差异,这两种产品在3个月时导致治疗部位类似的变黑。
■这项研究表明,与碘化钾或氟化亚锡结合使用的氟化银对于有特殊需要的成年人在光滑表面病变中实现龋齿阻止的有用性。需要告知患者,两者都会发生病变的长期染色,类似于二氟化银。
UNASSIGNED: Discoloration of carious lesions after application of silver diamine fluoride lowers patient acceptance and limits its wider use for caries arrest.
UNASSIGNED: To assess lesion and tooth color changes from 2 novel silver fluoride (AgF) products and its relationship to caries activity (clinical visuo-tactile scores) and bacterial load (using laser fluorescence with the DIAGNOdent).
UNASSIGNED: A split-mouth design was followed, with matched smooth surface carious lesions in the same arch in adults with special needs randomized for 1-min treatments with AgF/potassium iodide (KI) (Riva Star Aqua, SDI) and AgF/stannous fluoride (SnF2) (Caries Status Disclosing Solution; Whiteley). Standardized images taken at baseline, immediately postoperatively, and at 3-mo review were subjected to digital image analysis to calculate delta-E and to track changes in luminosity of carious lesions.
UNASSIGNED: Twelve participants were recruited in the study. A total of 56 teeth (28 pairs) were included. Significantly greater changes were seen in treated lesions than in the adjacent noncarious natural tooth structure, both immediately after treatment and at the 3-mo review (P < 0.0001). Color change and caries activity were not affected by tooth type, tooth location, plaque status, salivary status, or special needs condition. AgF/SnF2 caused transitory darkening immediately on application, while AgF/KI caused the immediate formation of yellow deposits (silver iodide). Both products caused significant darkening of treated lesions at 3 mo (P = 0.0009; P = 0.0361), with no differences between them (P = 0.506). Responding lesions showed larger and more perceptible color changes immediately after either AgF application (P = 0.002; P = 0.024).
UNASSIGNED: Both AgF products were highly effective for caries arrest in this patient population. Despite minor differences in the appearance of treated lesions at the time of application, both products lead to similar darkening of treated sites at 3 mo.
UNASSIGNED: This study shows the usefulness of silver fluoride used in conjunction with potassium iodide or stannous fluoride for achieving caries arrest in smooth surface lesions in adults with special needs. Patients need to be informed that long-term staining of the lesion occurs with both, similar to silver diamine fluoride.
