现行的口腔照明灯一般采用卤素灯冷光源照明,避免了热光源照明所致的热传导给病员和操作人员带来的不适。但由于仍然沿用远距离(60～90cm)、宽照射野(16～18×6～8cm)投照,在洞状口腔操作环境里不免产生阴影,影响操作,尤其是对小范围的精细操作—诸如窝洞的制备,去湿、干燥和充填以及冠、桥类修复牙的准备等影响更大。为此,国外率先推出了将光导纤维置入手机头的导光手机,为牙体制备提供了更加清晰的照明。现在,美国MDT公司出的新一代防污染牙科综合治疗机首次将光纤纳入口腔照明灯源的设计,从而使口腔内的操作视野变得更加清晰无碍。此口腔光纤照明灯 The current oral lighting commonly used halogen lamp cold light illumination, to avoid heat conduction caused by the hot light source to the sick and the operator caused discomfort. However, due to still using the long distance (60 ~ 90cm), wide radiation field (16 ~ 18 × 6 ~ 8cm) projection, in the oral cavity operating environment inevitably produce shadows, affecting the operation, especially for a small range of fine operation - Such as the preparation of cavities, dehumidification, drying and filling and crown, bridge repair tooth preparation and other more influential. To this end, the first overseas introduction of the optical fiber into the phone’s head light guide phone for tooth preparation provides a more clear lighting. Now, a new generation of anti-contamination dental treatment machines from MDT Company of the United States is the first to incorporate optical fibers into the design of dental light sources to make the operating field of the oral cavity clearer.
