随着龋病患病率及龋病发展速率的逐年下降,龋病的早期诊断越显重要。光导纤维透照法在可见光照射影像技术中是一种比较切实可行的方法。作者在其基础上开发出光导纤维透照数字照相技术以克服原有方法中存在的主观因素干扰。 材料和方法 光导纤维透照数字影像技术(digital imaging fiber-optic transillumination,DIFOTI~(TM))的设备主要由以下几个部分构成:①低电压21W卤化金属短弧灯,接有可调稳压电源,②光波长为450～470nm的6张滤光片,间隔50nm,③单纤维或多纤维光导纤
With the prevalence of caries and the declining rate of caries development, the early diagnosis of caries becomes more and more important. Optical fiber transmission method in the visible light imaging technology is a more practical method. On this basis, the author developed optical fiber transmission digital photography technology to overcome the subjective factors existing in the original method. Materials and Methods The equipment of digital imaging fiber-optic transillumination (DIFOTITM) consists of the following parts: ① Low-voltage 21W metal halide short arc lamp with adjustable voltage regulator Power supply, ② 6 filters with 450nm ~ 470nm wavelength, 50nm spacing, ③ Single or multi-fiber optical fiber
