高精度的选择性牙石去除最好是使用激光以高脉冲重复频率工作，聚焦到小光点大小，以限制对声音组织的损害。传统的闪光灯泵浦的Er：YAG激光器不太适合这一目的，但新的二极管泵浦的固态(DPSS)Er：YAG激光器已经可以在高脉冲重复频率下工作。这项研究的目的是确定是否可以使用图像引导激光消融来选择性地去除牙齿表面的结石，同时对潜在的牙骨质和牙本质造成最小的损害。采用DPSS Er：YAG激光系统，在1500~1750 nm波长连续扫描SWIR图像，对10颗拔除牙齿的牙石进行选择性去除。使用数字显微镜和光学相干断层扫描来评估去除的选择性。结石被移除，对底层牙骨质和牙本质的损害最小。
Selective removal of dental calculus with high precision is best accomplished using lasers operating at high pulse repetition rates focused to a small spot size to limit damage to sound tissues. Conventional flashlamp pumped Er:YAG lasers are poorly suited for this purpose, but new diode-pumped solid state (DPSS) Er:YAG lasers have become available operating at high pulse repetition rates. The purpose of this study was to determine if image-guided laser ablation can be used to selectively remove calculus from tooth surfaces with minimal damage to the underlying sound cementum and dentin. A DPSS Er:YAG laser system was used to selectively remove calculus from ten extracted teeth using sequential SWIR images at 1500-1750-nm. The selectivity of removal was assessed using digital microscopy and optical coherence tomography. Calculus was removed with minimal damage to the underlying sound cementum and dentin.
