Provided in the present disclosure is an oral cavity examination method, including: acquiring an oral cavity image; performing median filtering and region segmentation operations on the image to obtain a first intermediate image; converting the first intermediate image from an RGB color space to an HSV color space to obtain a second intermediate image; determining a comparison threshold based on a tooth color; and determining a ratio of pixels within the comparison threshold to pixels of the second intermediate image based on the second intermediate image and the comparison threshold. The oral cavity examination method can set different comparison thresholds according to tooth colors of subjects, so as to perform targeted examination conforming to the characteristics of different subjects, making the ratio of the pixels within the comparison threshold to the pixels of the second intermediate image determined based on the second intermediate image and the comparison threshold more accurate and effective than the ratio determined by the conventional method, and thus facilitating subsequent evaluation of oral cavity health condition.
