In clinical practice, cervical erosion is divided into three degrees. It is considered first degree when the area of cervical erosion is within one-third; it falls under the second degree if it exceeds one-third but is within two-thirds; and it is classified as third degree if the area of cervical erosion exceeds two-thirds. Preliminary judgments can be made based on the results of the examination. Regardless of the degree of cervical erosion, timely treatment is necessary. Generally, normal condition can be restored with systematic treatment based on the attending physician's advice.
