White spot lesion (WSL) infiltration has been recommended immediately after debonding of orthodontic brackets. It is however not clear if established inactive WSLs can also be masked through infiltration. Orthodontic treatment of a 19-year-old patient had to be terminated prematurely due to development of multiple WSLs of varying severity. Three months after debonding, the patient presented for lesion infiltration. After etching with 15% HCl gel and re-wetting of the dried surfaces it seemed that a good outcome could be expected. Lesion infiltration led to complete masking of less severe WSLs. The visual appearance of moderate and severe WSLs was improved but they were still visible after treatment. Inactive WSLs may not represent an increased caries risk, but patients are often bothered esthetically. Infiltration by repeated etching might be a viable approach even for inactive WSLs. Controlled clinical trials are needed to investigate the long-term performance of this technique.
正畸托槽拆除后，建议立即进行白斑病变（WSL）渗透治疗。然而，对于已形成的非活动性WSL是否也能通过渗透治疗被掩盖尚不清楚。一名19岁患者因出现多个严重程度不同的WSL而不得不提前终止正畸治疗。托槽拆除三个月后，该患者前来进行病变渗透治疗。用15%盐酸凝胶酸蚀并重新湿润干燥表面后，似乎有望取得良好效果。病变渗透治疗使不太严重的WSL完全被掩盖。中度和重度WSL的外观有所改善，但治疗后仍可见。非活动性WSL可能并不意味着龋齿风险增加，但患者通常会受到美观方面的困扰。即使对于非活动性WSL，反复酸蚀渗透治疗可能也是一种可行的方法。需要进行对照临床试验来研究该技术的长期效果。
