最近的研究表明，近红外（IR）成像可用于获取高对比度的图像，根龋和结石的根表面上提取的牙齿在波长大于1450 nm。本研究的目的是确定图像引导的激光消融术是否可以用于选择性地去除牙齿表面的牙石，同时对下面的健康牙骨质和牙本质的损伤最小。在这项研究中，在1500-1700 nm的连续近红外图像被用来引导二极管泵浦（DPSS）的Er：YAG激光器的10个提取的牙齿的根面结石的去除。去除的选择性进行了评估，使用数字显微镜，光学相干断层扫描，和表面轮廓。结石被迅速清除，对下面的健康牙骨质和牙本质的损害最小。图像引导消融术具有高选择性，平均结石清除量是平均牙骨质丢失量的27倍以上。我们已经证明，近红外图像引导的激光消融可用于选择性去除牙结石从根表面离体。此外，我们已经证明，二极管泵浦的固态Er：YAG激光器是非常适合选择性去除。
Recent studies have demonstrated that near-infrared (IR) imaging can be used to acquire high-contrast images of root caries and calculus on the root surfaces of extracted teeth at wavelengths longer than 1450 nm. 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. In this study, sequential near-IR images at 1500–1700 nm were used to guide a diode-pumped (DPSS) Er:YAG laser for the removal of calculus from the root surfaces of 10 extracted teeth. The selectivity of removal was assessed using digital microscopy, optical coherence tomography, and surface profilometry. Calculus was removed rapidly with minimal damage to the underlying sound cementum and dentin. Image-guided ablation achieved high-selectivity, the mean volume of calculus removal was more than 27 times higher than the mean loss of cementum. We have demonstrated that near-IR image-guided laser ablation can be used for the selective removal of calculus from root surfaces ex vivo. Additionally, we have demonstrated that a diode-pumped solid-state Er:YAG laser is well suited for selective removal.
