The aim of the study was to study clinical and histological changes in the treatment of discoloration using different systems for professional tooth whitening. The study involved 76 patients. Patients of group 1 had their teeth whitened by the Amazing White Universal Extra photochemical activation system, and group 2 had their teeth whitened by the Beyond Polus system. Each group was divided into 3 more subgroups depending on the method of remineralization and the applied toothpaste (SENSITIVE ULTRA and SENSODYNE Rapid Relief). To assess teeth hyperesthesia before, immediately after and 14 days after the bleaching procedure, we used the prevalence index of teeth hyperesthesia, the intensity index of teeth hyperesthesia, and the Schiff sample. We also used a digital rating scale for patients. 100 teeth extracted for orthodontic indications were subjected to histological examination. The occurrence of hyperesthesia of teeth during professional bleaching was revealed in 100% of cases. Significant structural changes were registered in the enamel and dentin of the teeth, most pronounced during photo-whitening. The treatment based on zinc-substituted hydroxyapatite carbonate in combination with laserophonophoresis against the background of use the toothpaste SENSODYNE Rapid Relief had the greatest remineralizing effect.
本研究的目的是研究使用不同专业牙齿美白系统治疗牙齿变色时的临床和组织学变化。该研究纳入了76名患者。第1组患者使用Amazing White Universal Extra光化学激活系统进行牙齿美白，第2组患者使用Beyond Polus系统进行牙齿美白。根据再矿化方法和所使用的牙膏（SENSITIVE ULTRA和舒适达速效抗敏牙膏），每组又分为3个亚组。为了评估漂白程序前、后即刻以及14天后牙齿的感觉过敏情况，我们使用了牙齿感觉过敏患病率指数、牙齿感觉过敏强度指数和席夫样本。我们还对患者使用了数字评分量表。对100颗因正畸需要拔除的牙齿进行了组织学检查。结果显示，在专业漂白过程中，100%的病例出现了牙齿感觉过敏。在牙齿的釉质和牙本质中记录到了显著的结构变化，在光美白过程中最为明显。在使用舒适达速效抗敏牙膏的背景下，基于碳酸锌取代羟基磷灰石联合激光超声透入疗法的治疗具有最大的再矿化效果。
