恒牙冠变色是由外伤、乳牙根尖周病变、药物和全身性疾病引起的。牙冠变色的治疗方法有漂白或牙冠修复。然而，这些方法不适用于儿童的生长发育时期。在这项研究中，我们使用了BeautiCoat (TM) (Shofu Inc., Kyoto, Japan)，这是一种牙齿表面涂层材料，含有高浓度的控释氟化物，可以暂时改善牙冠颜色。除了涂层剂的剪切结合强度、牙齿表面状况和附着时间外，我们还评估了底漆对牙齿表面特性的影响。此外，我们还调查了患者对颜色改善的满意度。结果表明，该处理剂对牙釉质表面无不良影响。涂层材料本身具有较高的剪切结合强度。根据临床应用中脱落和破裂的观察，我们发现涂层材料在严格防潮的条件下使用并避免了闭塞区域，可以保持长期附着。接受治疗的儿童及其父母对颜色的改善非常满意。这些结果表明，这种涂层材料适合改善儿童时期变色牙齿的颜色。(C) 2013日本儿科牙科学会。Elsevier Ltd.出版。版权所有。
Crown discoloration of permanent teeth is caused by trauma, periapical lesions of the deciduous teeth, pharmaceuticals, and systemic diseases. Crown discoloration has been treated with bleaching or crown restoration. However, these methods are not appropriate during the growth and development period of children.In this study, we used BeautiCoat (TM) (Shofu Inc., Kyoto, Japan), a tooth-surface coating material that contains high levels of controlled-release fluoride, that temporarily improves crown color. We evaluated the effect of the primer on tooth-surface characteristics in addition to the coating agent's shear bond strength, tooth-surface condition, and duration of attachment. Additionally, we surveyed patients' satisfaction with the color improvement.The results showed no adverse effects of the primer on the enamel surface. The coating material itself showed a high degree of shear bond strength. Based on observations of shedding and fracturing in clinical applications, we found that the coating material maintained long-term attachment if applied under conditions of strict moisture prevention and it avoided areas of occlusion. Treated children and their parents were highly satisfied with the color improvement. These results suggest that this coating material is appropriate for improving the color of discolored teeth during childhood. (C) 2013 The Japanese Society of Pediatric Dentistry.
