Several studies highlighted how the ameloblasts, secretory cells responsible of the tooth enamel formation, are highly sensitive to changes in their environment. Due to enamel maturation, their dysfunctions during a limited period of tooth development may lead to permanent morphological consequences, namely Developmental Enamel Defects (DED). The aim of this study was to show the advantages of Er:YAG laser for DED treatment.
The case report presented describes the treatment, by Er:YAG laser, of some DED lesions present in the upper incisors of a young patient. The settings used were: 1W power, 100mJ energy, 10 Hz frequency corresponding to a Fluence of 0.318 J/cm per pulse or 3, 18 J/cm.
The patient, even in absence of local anesthesia, did not feel any pain or discomfort during and after intervention. Follow-up at 2, 6 and 12 months did not show any problems in an aesthetic point of view as well as regarding hypersensitivity.
The use of Er:YAG laser for the treatment of developmental enamel defects in frontal teeth is a safe, painless and minimally invasive; moreover, it is able to assure a good aesthetic result.
多项研究强调，成釉细胞作为负责牙釉质形成的分泌细胞，对其环境变化高度敏感。由于釉质成熟，它们在牙齿发育的有限时期内功能失调可能会导致永久性形态后果，即发育性釉质缺陷（DED）。本研究的目的是展示铒激光治疗DED的优势。
本病例报告描述了用铒激光治疗一名年轻患者上颌切牙存在的一些DED病变。所使用的参数设置为：功率1W、能量100mJ、频率10Hz，对应每脉冲能量密度为0.318J/cm²或3.18J/cm²。
患者即使在未进行局部麻醉的情况下，在干预期间及之后也未感到任何疼痛或不适。在2个月、6个月和12个月时的随访未显示在美观方面以及牙齿过敏方面存在任何问题。
使用铒激光治疗前牙发育性釉质缺陷是安全、无痛且微创的；此外，它能够确保良好的美观效果。
