Which symptom is the most important indicator of malignant lesions?

Paresthesia is considered the most important indicator of malignant lesions because it often signifies nerve involvement, which can occur when a tumor is invading adjacent tissues or affecting the nerves in the area. The presence of paresthesia can indicate that there is a more serious underlying pathological process at play, as malignant lesions can infiltrate local structures, including nerves, leading to sensations such as tingling, numbness, or a burning feeling in the tissues.

Pain, while also significant, is a less specific symptom since it can arise from a variety of dental or non-dental conditions, not just malignancy. Teeth movement and tooth resorption are generally associated with various dental issues, including periodontal diseases or other benign conditions, but they are not as direct indicators of malignancy as paresthesia. Therefore, the presence of paresthesia in a dental examination raises a red flag for possible malignant processes, making it a critical symptom to assess.
