Children can be diagnosed with traumatic oral ulcers by a combination of disease history, oral trauma history, clinical symptoms, physical examination and pathological examination. Traumatic oral ulcers are more difficult to diagnose but have less diagnostic significance, and symptoms usually diminish quickly after removal of the persistent injury.
Therefore, the diagnosis of traumatic oral ulcers usually involves a three-step process of physical examination, etiological treatment and pathological examination.
The diagnosis of traumatic oral ulcers is made by first identifying whether the patient has had recurrent episodes of similar symptoms, then asking whether the patient has undergone surgery on the teeth or oral mucosa, and whether the patient has consumed irritating foods or medications of unknown nature. If these are present, an intra-oral examination is carried out to look for persistent physical and chemical irritants and remove them, i.e. treat the cause. If symptoms do not resolve, further pathology should be performed to identify the cause.
