Complications, especially delayed alveolar healing, are common following equine cheek teeth extraction, however, limited objective information is available on the prevalence and nature of these problems.
To document the type and prevalence of complications that occur following equine cheek tooth extraction and to identify possible risk factors for these complications that could be used to predict their occurrence and hopefully reduce their prevalence.
Retrospective cohort study.
Clinical records of all cheek teeth extractions performed between February 2004 and September 2018 were examined and written questionnaires sent to owners. Details of post-extraction complications were analysed and logistic regression was used to evaluate potential associations between the likelihood of post-extraction nonhealing alveolus managed by the authors and the variables: age, breed, reason for extraction, Triadan position and extraction technique.
Post-extraction complications were recorded following 58/428 extractions giving an overall complication rate of 13.6%, that caused a longer term clinical problem in 34/428 (7.9%) cases, with complications being asymptomatic or quickly self-resolving in the other 24 cases (5.6%). The most frequent complication was alveolar bone sequestration, including alveolar infection. Risk of developing a post-extraction alveolar disorder managed by the authors (n = 53) increased following extraction of the mandibular 06s, 07s or 08s compared with all other cheek teeth combined (P = .001); for cheek teeth with apical infections (P = .002) compared with those without; and following repulsion or minimally invasive transbuccal extraction (MTE) than following oral extraction (P = .01 and P = .02 respectively).
Length of time between exodontia and survey data collection for some cases, use of clinical records and survey data and biases associated with decision to treat.
In agreement with previous studies, oral extraction had the lowest risk of complications. This study provides new information regarding the prevalence, types and risk of development of post extraction complications. Knowledge of these risk factors may help reduce these complications.
马属动物颊齿拔除后，并发症（尤其是延迟性肺泡愈合）很常见，但有关这些问题的普遍性和性质的客观信息有限。
记录马属动物颊齿拔除后发生的并发症的类型和发生率，并确定这些并发症发生的可能危险因素，以便预测其发生并降低其发生率。
回顾性队列研究。
检查了 2004 年 2 月至 2018 年 9 月期间进行的所有颊齿拔除术的临床记录，并向所有者发送了书面问卷。分析了拔牙后并发症的详细信息，并使用逻辑回归评估了拔牙后非愈合牙槽作者处理的可能性与以下变量之间的关联：年龄、品种、拔牙原因、Triadan 位置和拔牙技术。
58/428 例拔牙后出现拔牙后并发症，总并发症发生率为 13.6%，34/428（7.9%）例出现长期临床问题，其余 24 例（5.6%）无症状或迅速自愈。最常见的并发症是牙槽骨骨块，包括牙槽感染。与其他颊齿组合相比，作者处理的拔牙后牙槽疾病的风险（n=53）增加了下颌 06s、07s 或 08s 的拔牙（P=0.001）；与无根尖感染的颊齿相比（P=0.002）；与经口拔牙相比，排斥或微创经颊拔牙（MTE）（P=0.01 和 P=0.02）。
一些病例拔牙和调查数据收集之间的时间长短、临床记录和调查数据的使用以及治疗决策相关的偏倚。
与以往研究一致，经口拔牙的并发症风险最低。本研究提供了拔牙后并发症的发生率、类型和发展风险的新信息。了解这些危险因素可能有助于减少这些并发症。
