Hypomineralization represents one of the most common defects in tooth crowns. Thanks to a wide understanding of aesthetics, patients request a treatment to resolve these defects. Different techniques are available, such as crowns/veneers, traditional restorative treatments, microabrasion, whitening, remineralizing agents and infiltration technique. The objective of this trial is to assess the effectiveness of superficial infiltration with Icon (DMG, Hamburg, Germany) on the attenuation of crown hypomineralized lesions of various etiological origins with a 12-month follow-up. Seventeen patients with white defects of enamel in the aesthetic sector were selected. The infiltration procedure was carried out following the manufacturer's instructions. Intraoral photographs were taken before and directly after treatment in order to document the immediate change in colour. Check-ups were performed 1 and 12 months later. All the defects which were treated showed a degree of attenuation. The teeth affected by molar incisor hypomineralization (MIH) showed partial attenuation in 8 cases, and only in one case the defect disappeared. Regarding the post-trauma cases, 6 were partially attenuated and 2 disappeared. The post orthodontic defects disappeared in 6 cases and were attenuated in 5. All incipient caries defects were completely hidden. Four out of 6 cases of fluorosis disappeared. Diagnosis plays a key role in guiding the dental clinical selection of treatment. While it has always been possible to achieve a high level of attenuation in cases of fluorosis and lesions of caries origin, cases of MIH should probably be treated using more invasive techniques. Post-trauma lesions should be infiltrated with caution, and only after having informed the patient of the possible ineffective outcome.
釉质发育不全是牙冠最常见的缺陷之一。由于对美学有广泛的认识，患者要求治疗以解决这些缺陷。有不同的技术可供选择，如牙冠/贴面、传统修复治疗、微研磨、美白、再矿化剂和渗透技术。本试验的目的是评估 Icon（DMG，汉堡，德国）表面渗透对各种病因釉质发育不全病变的衰减效果，随访时间为 12 个月。选择了 17 名有美学区釉质白色缺损的患者。按照制造商的说明进行渗透程序。在治疗前和治疗后直接进行口腔内摄影，以记录颜色的即时变化。在 1 个月和 12 个月后进行检查。所有接受治疗的缺陷均显示出一定程度的衰减。受磨牙-切牙釉质发育不全（MIH）影响的牙齿在 8 例中显示部分衰减，仅在 1 例中缺陷消失。对于创伤后病例，6 例部分衰减，2 例消失。正畸后缺陷在 6 例中消失，5 例衰减。所有初期龋损完全隐藏。氟斑牙的 4 例中有 6 例消失。诊断在指导牙科临床治疗选择方面起着关键作用。虽然在氟斑牙和龋病来源的病变中一直可以达到较高的衰减水平，但 MIH 病例可能需要使用更具侵袭性的技术进行治疗。应谨慎对待创伤后病变的渗透治疗，并在告知患者可能无效的结果后进行。
