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).
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.
探讨影响恒牙外伤性牙损伤（TDI）每颗牙就诊次数的因素。
选择在利兹牙科研究所接受 TDI 治疗的 100 名儿童的回顾性便利样本。建立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。使用 SPSS 18.0 和 MLWIN 分析包括年龄、性别、邮政编码、就诊次数、治疗方式、受伤牙齿数量、牙周和硬组织诊断类型、愈合方式、根成熟度、牙髓和牙齿存活以及同一牙齿是否有既往或后续创伤史等数据。
100 名患者的 186 颗牙齿受到创伤。每颗牙的总就诊次数中位数为 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（P < 0.05）。从家到诊所的距离每增加一英里，每月就诊次数减少 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增加了 44%（0.362；SE 0.105），与无牙周损伤相比，复杂牙周损伤的诊断增加了 30%（0.260；SE 0.124），与无牙周损伤相比，简单牙周损伤的诊断增加了 31%（0.271；SE 0.124），与活髓牙相比，牙髓坏死的诊断和治疗增加了 26%（0.230；SE 0.080）就诊次数。在患者水平上，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和患者家之间的距离都显著影响 TDI 的治疗就诊次数。
