- Normal team
- description
- Subjects who have problem at third molar of impacted tooth need to receive a surgery with general anesthesia. Subjects must: Should have a blood exam (20ml) before the surgery. Site staff must: Collect subjects' saliva once a day (in the morning before breakfast) for 3 consecutive days. Collect a 0.5x0.5Cm2 tissue sample around third molar during the surgery.
- label
- Oral dysplasia
- description
- Subjects who are diagnosed with dysplasia of oral cavity. Subjects must: Should have a blood exam (20ml/each time) before the surgery and 3 months after the surgery. In the case the disease recurs after the surgery, subjects need to receive the surgery again and take another blood exam before the surgery and 3 months after the surgery. Before the surgery site staff must: Collect subjects' saliva once a day (in the morning before breakfast) for 3 consecutive days. Collect a 0.5x0.5Cm2 tissue sample of the tumor during the surgery.
