To investigate the evolution of resin infiltrated white spot lesions (WSLs) during 10 month of fixed orthodontic appliance therapy using the photographic examination method.
Twelve patients with mild decalcifications prior to the orthodontic treatment were examined once each month. At aggravation of the WSLs, by patients who fail to maintain good oral hygiene, the brackets were taken down, the lesions were infiltrated with resin (ICON) and the brackets were bonded in place. WSLs were evaluated from intraoral photographs taken before and during the treatment.
35.2% of existing lesions aggravated in the first 6 months of treatment. 41.2 % of the W.S.L. were considered severe and were infiltrated. In the next 10 month of orthodontic treatment 92.5% of the infiltrated WSLs were clinically stable.
This clinical study showed a positive evolution of the resin infiltrated WSLs during the fixed orthodontic therapy. This is especially important for patients with long periods of treatment like interdisciplinary orthodontic-orthognathic surgery cases or patients that are refractory to oral hygiene measures.
采用摄影检查方法，研究固定正畸矫治器治疗10个月期间树脂浸润性白斑病变（WSLs）的演变情况。
12例正畸治疗前有轻度脱矿的患者每月接受一次检查。对于因未能保持良好口腔卫生而导致WSLs加重的患者，拆除托槽，用树脂（ICON）浸润病变部位，然后重新粘结托槽。根据治疗前和治疗期间拍摄的口腔内照片对WSLs进行评估。
35.2%的现有病变在治疗的前6个月加重。41.2%的WSLs被认为严重并进行了浸润治疗。在接下来的10个月正畸治疗中，92.5%的浸润性WSLs临床稳定。
这项临床研究表明，在固定正畸治疗期间，树脂浸润性WSLs有积极的演变。这对于治疗周期长的患者，如正畸-正颌联合手术病例或对口腔卫生措施难以耐受的患者尤为重要。
