Patient: Description of condition (onset, main symptoms, hospital visited, etc.): After I had my right two wisdom teeth extracted last year, the right tooth became embedded. There was periodontal disease in the oral panoramic film, shallow caries in the lower right 6 distal to middle, and partial resorption of alveolar bone in the whole mouth. There is no treatment. Seeing that you are an expert in this field, with high medical skills and good medical ethics, I would like to ask you to help me. Beijing Stomatological Hospital, Department of Endodontics, Fang Bisong: First, go to our hospital periodontal department for systematic periodontal treatment, and then come to me to solve the problem of tooth blockage after the treatment. Patient: Hello Professor Fang, I am very happy to see your reply, I will do as you say, thank you in advance. Beijing Stomatological Hospital Endodontics Department Fang Bisong: You are welcome, I hope you can protect your teeth. Patient: Hello Professor Fang, I will arrive in Beijing tomorrow (Tuesday) and I am going to come to the evening to register for Wednesday’s periodontal cleaning. I am from out of town and would like to know how long the treatment will take. Thank you very much. Beijing Stomatological Hospital Endodontics Department Fang Bisong: Sorry, I just saw it today. You should clean your teeth first, and I will definitely help you solve the problem of dental congestion. Patient: Professor Fang: Hello, you have excellent medical skills and high medical ethics, you have many fans, I wonder if you still remember me, the out-of-town patient who came all the way to you and left due to an accident at home. Your seemingly simple words “I will help you solve the problem of dental congestion” made the patient feel warmth and hope, while for the doctor it reflected your profound professional knowledge, rich clinical experience and exquisite medical skills. I would like to send you my most sincere wishes on the occasion of Chinese New Year: I wish you and your family good health and happiness! Good luck in the Year of the Dragon! Fang Bisson, Department of Endodontics, Beijing Stomatological Hospital: Thank you for your blessing, I remembered, don’t worry! I will definitely give you an extra number. Patient: I’m so happy to see your reply today, thank you so much. I will probably come back to Beijing in August. I’m sorry for the trouble I caused you by delaying your rest time last time. In order to use less of your precious time when I come for treatment and to save a little more time for other patients, I would like to give you a brief report of my condition. Two years ago, I went to the doctor after eating barbecue, and the doctor said that the wisdom teeth were useless and there would be endless problems if they were not extracted, so I had both upper and lower right wisdom teeth extracted at the same time. The tooth was not an obstructed tooth and was not decayed. On the day of tooth extraction, I felt a foreign body in my cheek, but I did not see any foreign body in the film. I felt that the right tooth was close to my cheek and was on my cheek, and when I looked at it in the mirror, the lower right 7 was slightly sunken, and now the center of the crown surface of 7 had become black. If you are healthy and happy, the patients will not suffer, and millions of patients need you and like you.
