Previous studies have established that carious lesions can be imaged with high contrast using near-IR wavelengths coincident with high water absorption, namely 1450-nm, without the interference of stains. It has been demonstrated that computer-controlled laser scanning systems utilizing IR lasers operating at high pulse repetition rates can be used for serial imaging and selective removal of caries lesions. In this study, a point-to-point scanning system was developed integrating a 1450-nm diode laser with the CO ablation laser. This approach is advantageous since it does not require an expensive near-IR camera. In this pilot study, we demonstrate the feasibility of a combined NIR and IR laser system for the selective removal of carious lesions.
先前的研究已经证实，利用与高吸水性相匹配的近红外波长（即1450纳米），龋损能够以高对比度成像，且不受污渍干扰。已经证明，利用以高脉冲重复率运行的红外激光的计算机控制激光扫描系统可用于龋损的连续成像和选择性去除。在本研究中，开发了一种将1450纳米二极管激光器与CO消融激光器集成的点对点扫描系统。这种方法具有优势，因为它不需要昂贵的近红外相机。在这项初步研究中，我们证明了近红外和红外激光联合系统用于选择性去除龋损的可行性。
