Description for medicine or protocol of treatment in detail:

 

纳入标准:

(1)年龄为18-65周岁; (2)于2017年4月1日至2022年12月31日于浙江大学医学院附属口腔医院牙周科就诊,诊断为牙周炎并有初诊牙周大表; (3)初诊牙周大表前后3个月存在CBCT; (4)存在一侧上颌第一磨牙与第二磨牙均无缺失,且上颌第二磨牙未行根管治疗、无根折、牙根吸收或根尖周病变等。

Inclusion criteria

(1) Aged between 18 and 65 years. (2) Received treatment at the Periodontal Department of the Stomatological Hospital Affiliated to Zhejiang University School of Medicine between April 1, 2017, and December 31, 2022; was diagnosed with periodontal disease and had a preliminary periodontal examination at that time. (3) CBCT scans were taken within 3 months before and after the preliminary periodontal examination. (4) There is no absence of either the first or second maxillary molar on one side; in addition, the second maxillary molar has not undergone root canal treatment, and there are no signs of root fracture, root resorption, or periapical lesions.

排除标准:

(1)存在颌面部囊肿或肿瘤、上颌骨骨折; (2)CBCT图像不清晰,上颌后牙区存在影响图像质量及测量结果的修复体、种植体、金属充填体等; (3)抽烟、糖尿病、放化疗患者; (4)长期服用影响骨代谢或骨愈合的药物(如免疫抑制剂、苯妥英钠、双膦酸盐等);

Exclusion criteria:

(1) Presence of jaw and facial cysts or tumors, or maxillary fractures; (2) Unclear CBCT images, with restorations, implants, metal fillings, etc. in the posterior maxillary region that affect the quality of the images and the accuracy of the measurements; (3) Patients who smoke, have diabetes, or have undergone radiation or chemotherapy; (4) Patients who have been taking medications that affect bone metabolism or bone healing for a long time (such as immunosuppressants, phenytoin sodium, bisphosphonates, etc.).
