Description

Technical Field

[0001] The utility model relates to the technical field of dentistry, and particularly relates to a triple-purpose oral digital observation instrument. Background Art

[0002] At present, under the auxiliary illumination of LED lighting, a group of miniature lenses in an ordinary oral digital observation instrument transmit an object to a CMOS / CCD imaging surface, and through the processing of an ISP / DSP circuit, the signal is transmitted to a display or the signal is converted into an image recognizable by a computer through software.

[0003] Clinically, dentists usually need to rely on traditional oral digital observation instruments (white light) to detect early caries. The diagnosis of open caries lesions is relatively simple, but for hidden caries lurking under the intact tooth surface, the diagnosis is difficult. Due to the influence of the tooth anatomical structure and poor cleaning effectiveness, the incidence of adjacent surface hidden caries is higher clinically. However, since there are no symptoms in the early stage, and in addition, before the adjacent marginal ridge of the diseased tooth is damaged, the appearance of the diseased tooth is intact and it is difficult to be detected by the naked eye, so the clinical misdiagnosis rate is high.
