铒：钇-铝石榴石激光（Er：YAGL）治疗牙本质敏感症主要是利用其热效应，激光作用于牙体的敏感部位并产生高温，熔融的牙本质小管表面的有机物变性凝固并封闭牙本质小管，管内液体流动性降低而产生脱敏效果。激光照射改变神经纤维膜对钠和钾离子的通透性，使神经末稍动作电位增加，兴奋性降低，进一步起到镇痛的作用。Er：YAGL具有较高的抑菌和杀菌能力，止血作用强，可增加牙本质的抗酸性能，对牙髓组织损伤小。Er：YAGL有着较好的即刻及远期效果，且投照部位明确，收效快，适用于单颗牙、多颗牙甚至全口牙敏感症的改善和恢复。Er：YAGL的吸水性较钕：钇-铝石榴石激光和CO2激光高，可以有效地消融牙本质和釉质，因此，Er：YAGL在牙本质敏感症中的应用受到了越来越多的关注。本文就Er：YAGL的脱敏机制和特点等研究进展作一综述。
