Hypomineralized enamel defects frequently are manifest as a mottled-white appearance and can be associated with variable degrees of discrete yellow-brown intrinsic staining. Numerous treatment approaches have been proposed, ranging from bleaching to enamel reduction to restorative techniques. Bleaching of hypomineralized enamel lesions, using 1 to 2 applications (10 to 15 minutes each) of 5% sodium hypochlorite, has been applied clinically. Treatment using this approach has proven successful in removing yellow-brown discolorations from lesions in young permanent teeth. Young permanent incisors with yellow-brown intrinsic discolorations can often be treated by a simple and conservative bleaching protocol using sodium hypochlorite.
矿化不足的釉质缺损常常表现为斑驳的白色外观，并且可能伴有不同程度的散在性黄褐色内源性染色。已经提出了许多治疗方法，从漂白到釉质磨除再到修复技术。临床上已应用5%次氯酸钠1至2次（每次10至15分钟）对矿化不足的釉质病损进行漂白。使用这种方法的治疗已证明成功地去除了年轻恒牙病损中的黄褐色色素沉着。具有黄褐色内源性色素沉着的年轻恒切牙通常可以通过使用次氯酸钠的简单且保守的漂白方案进行治疗。
