Surface sealants are widely used as a prevention strategy and are indicated for young patients with insufficient oral hygiene who also need plaque removal by professional tooth cleaning. The aim of this study was to evaluate discoloration of surface sealants by plaque disclosing solutions and to test to what extent this discoloration can be reduced again by professional tooth cleaning.
In all, 96 extracted lesion-free human teeth were randomly assigned to treatment with either Pro Seal® (PS; Opal Orthodontics, South Jordan, UT, USA) or Opal®Seal™ (OS; Reliance Orthodontic Products, Itasca, IL, USA). Color evaluations after application of the plaque disclosing solution Mira-2-Ton® (Hager & Werken, Duisburg, Germany) were performed using a clinical spectrophotometer. Staining and polishing were repeated once. Color differences (∆E) above 3.77 were regarded as clinically relevant.
All sealants showed high, clinically relevant ∆E values after the first staining. Polishing led to significantly decreased ∆E values on PS-treated teeth; however, the median ∆E value remained above the clinically relevant threshold. Polishing on OS-treated teeth only slightly reduced ∆E values. After professional tooth cleaning both PS and OS showed clinically relevant ∆E values.
Surface sealants show clinically relevant discoloration after exposure to plaque disclosing solution under in vitro conditions. Such discolorations could not be removed by professional tooth cleaning. Thus, in clinical practice, plaque disclosing solutions might cause esthetic deficits in surface sealant-treated teeth. The impact of plaque disclosing solutions under clinical conditions (e.g., in the presence of saliva and by various aspects of a person's nutrition) should be investigated in clinical studies.
表面封闭剂作为一种预防策略被广泛使用，适用于口腔卫生不足且还需要专业洁牙去除牙菌斑的年轻患者。本研究的目的是评估菌斑显示剂对表面封闭剂的染色情况，并测试专业洁牙能在多大程度上再次减少这种染色。
总共96颗无病变的拔除人牙被随机分配接受Pro Seal®（PS；美国犹他州南乔丹市的Opal Orthodontics公司）或Opal®Seal™（OS；美国伊利诺伊州伊塔斯卡市的Reliance Orthodontic Products公司）处理。使用临床分光光度计在应用菌斑显示剂Mira-2-Ton®（德国杜伊斯堡的Hager & Werken公司）后进行颜色评估。染色和抛光重复一次。颜色差异（∆E）大于3.77被视为具有临床相关性。
所有封闭剂在首次染色后均显示出较高的、具有临床相关性的∆E值。抛光使PS处理的牙齿上的∆E值显著降低；然而，∆E值中位数仍高于临床相关阈值。OS处理的牙齿上的抛光仅略微降低了∆E值。专业洁牙后，PS和OS均显示出具有临床相关性的∆E值。
在体外条件下，表面封闭剂在接触菌斑显示剂后会出现具有临床相关性的染色。这种染色不能通过专业洁牙去除。因此，在临床实践中，菌斑显示剂可能会导致表面封闭剂处理的牙齿出现美学缺陷。应在临床研究中调查菌斑显示剂在临床条件下（例如，在有唾液和个人营养的各种情况下）的影响。
