To investigate in children the factors that influence the number of visits per tooth following traumatic dental injuries (TDI) to the permanent dentition.
A retrospective convenient sample of 100 children who had been treated for TDI at Leeds Dental Institute was identified. A multilevel negative binomial regression model was developed to identify factors influencing the number of visits per tooth. Data including age, gender, postcode, number of visits, treatment provided, number of teeth injured, type of periodontal and hard tissue diagnoses, healing modality, root maturity, pulp and tooth survival, and any history of previous or subsequent trauma to same tooth were analysed using SPSS 18.0 and MLWIN.
186 teeth were affected by trauma in 100 patients. Median total number of visits per tooth was six visits with a range of 1-22 visits. The factors that were found to influence number of visits included: distance travelled, hard tissue diagnosis, periodontal injury diagnosis and pulp survival (P < 0.05). A mile increase in distance travelled from home to clinic led to a 1.2% reduction in the number of visits per month (-0.012; SE 0.005), a diagnosis of a severe hard tissue injury was associated with 44% increase (0.362; SE 0.105) compared to no hard tissue injury, a diagnosis of a complicated periodontal injury compared to no periodontal injury was associated with a 30% increase (0.260; SE 0.124), a diagnosis of a uncomplicated periodontal injury compared to no periodontal injury was associated with a 31% increase (0.271; SE 0.124) and a diagnosis and treatment for a non-vital tooth in comparison to a vital tooth led to a 26% increase (0.230; SE 0.080) in the number of visits. There was a significant variation in the number of treatment visits at patient level (0.260; SE 0.048). CONCLUSION Complicated hard tissue injuries, complicated and uncomplicated periodontal injuries, diagnosis and treatment for pulp necrosis and the distance between clinic and patient's home all significantly influenced the number of visits needed to treat TDI.
调查儿童在恒牙外伤性牙损伤（TDI）后影响每颗牙就诊次数的因素。
本研究采用回顾性便利抽样法，选取在利兹牙科研究所接受 TDI 治疗的 100 名儿童。建立了多水平负二项回归模型，以确定影响每颗牙就诊次数的因素。数据包括年龄、性别、邮政编码、就诊次数、治疗方法、受伤牙齿数量、牙周和硬组织诊断类型、愈合方式、根尖成熟度、牙髓和牙齿存活情况以及同一牙齿是否有既往或后续创伤史等。使用 SPSS 18.0 和 MLWIN 进行数据分析。
100 名患者的 186 颗牙齿受到创伤。每颗牙的平均总就诊次数为 6 次，范围为 1-22 次。影响就诊次数的因素包括：就诊距离、硬组织诊断、牙周损伤诊断和牙髓存活情况（P < 0.05）。从家到诊所的就诊距离每增加 1 英里，每月就诊次数就会减少 1.2%（-0.012；SE 0.005）；与无硬组织损伤相比，严重硬组织损伤的诊断与就诊次数增加 44%（0.362；SE 0.105）；与无牙周损伤相比，复杂牙周损伤的诊断与就诊次数增加 30%（0.260；SE 0.124）；与无牙周损伤相比，简单牙周损伤的诊断与就诊次数增加 31%（0.271；SE 0.124）；与活髓牙相比，诊断和治疗非活力牙与就诊次数增加 26%（0.230；SE 0.080）。患者水平的治疗就诊次数存在显著差异（0.260；SE 0.048）。
复杂的硬组织损伤、复杂和简单的牙周损伤、牙髓坏死的诊断和治疗以及诊所与患者家之间的距离均显著影响 TDI 的治疗就诊次数。
