Clinical Study on the Effect of Removal of Porphyromonas Gingivalis on Prognosis of Esophageal Cancer After Radical Surgery

Ultrasonic teeth cleaning: After gargling with compound chlorhexidine gargle or 3% hydrogen peroxide gargle for 1 minute, the teeth were cleaned by ultrasonic wave. After the teeth were cleaned, the wound was rinsed with 3% hydrogen peroxide to stop bleeding. Immediately after the ultrasonic cleaning, two pieces of tinidazole oral composite microneedle patch were applied to the upper and lower gums close to the inside of the first molar, especially on the tooth loss or damage, and the mouth was kept closed for 15 minutes. After the microneedle was fully degraded, the room could be left.
