The present dental bleaching case report describes a new method that precisely quantifies the daily wearing-times of the bleaching product by inserting a microsensor in the acetate custom tray. The bleaching efficacy was also discussed since the patient was previously submitted to enamel microabrasion.
The patient was submitted to enamel microabrasion in 1987, and bleaching treatment was performed in 2005. In 2017, re-bleaching was executed using 10% peroxide carbamide. The electronic microsensor, TheraMon (TheraMon® microelectronic system; Sales Agency Gschladt, Hargelsberg, Austria), was embedded in the labial region of the upper and lower acetate trays to evaluate the wearing-times of the acetate trays/bleaching product. The patient was instructed to wear the tray for 6 to 8 h/day while sleeping. After 24 days of bleaching treatment, the data obtained from the TheraMon electronic devices was collected and interpreted.
The patient did not entirely follow the bleaching treatment as recommended, as there was no evidence of use of the upper and lower trays for some days; additionally, the bleaching product was used for shorter and longer periods than was instructed.
The TheraMon microeletronic device precisely measured the wearing-times of the acetate tray/bleaching product during the bleaching treatment. Teeth submitted to enamel microabrasion presented with a healthy clinical appearance after 30 years.
Measuring the length and frequency of use of an acetate tray/bleaching product can be important to clinicians and patients for obtaining a controlled and adequate bleaching treatment.
本牙科漂白病例报告描述了一种新方法，通过在醋酸酯定制托盘内插入微传感器，精确量化漂白产品的每日佩戴时间。由于患者先前接受过牙釉质微研磨，因此还讨论了漂白效果。
患者于 1987 年接受牙釉质微研磨，于 2005 年进行漂白治疗。2017 年，使用 10%过氧化脲进行再漂白。电子微传感器TheraMon（TheraMon®微电子系统；Sales Agency Gschladt，Hargelsberg，Austria）嵌入上、下醋酸酯托盘的唇侧区域，以评估醋酸酯托盘/漂白产品的佩戴时间。患者被指示在睡觉时每天佩戴托盘 6-8 小时。在 24 天的漂白治疗后，收集并解释来自TheraMon 电子设备的数据。
患者没有完全按照推荐的漂白治疗方案进行治疗，因为有几天没有证据表明上、下托盘被使用；此外，漂白产品的使用时间比规定的时间短或长。
TheraMon 微电子产品在漂白治疗期间精确测量了醋酸酯托盘/漂白产品的佩戴时间。经过 30 年，接受牙釉质微研磨的牙齿呈现出健康的临床外观。
测量醋酸酯托盘/漂白产品的使用长度和频率对于临床医生和患者来说，对于获得控制和充分的漂白治疗非常重要。
