Abstract：
Unerupted teeth in dogs are fairly common and may develop an odontogenic cyst that causes destruction of the surrounding bone and affect adjacent teeth. We analyzed histological reports of cysts associated with unerupted teeth in a large population of dogs. Medical records and histopathological results of cysts associated with unerupted teeth were evaluated from all dogs treated at a private referral veterinary dental clinic over a 10-year period (2012-2022). A total of 192 dogs with 279 cysts associated with one or more unerupted teeth were included in the study. Brachycephalic breeds were overrepresented. The most affected were Tibetan Spaniels with 58 dogs (30%) and Boxers with 48 dogs (25%). The most common affected tooth was the mandibular first premolar tooth with 238 (84%) cysts. Of the total of 279 cysts, 208 (75%) were histopathologically examined. None of the cysts examined contained malignant changes. Based on these 208 cysts, the probability of finding a cyst with malignant changes in a population of dogs is 0-1.4% (confidence interval 95%).
摘要：
狗的未萌出的牙齿相当常见，可能会发生牙源性囊肿，导致周围骨骼的破坏并影响相邻的牙齿。我们分析了大量狗中与未萌出牙齿相关的囊肿的组织学报告。在10年期间（2012-2022年），从在私人转诊兽医牙科诊所治疗的所有犬中评估了与未萌出牙齿相关的囊肿的医疗记录和组织病理学结果。该研究包括总共192只狗，其中279只囊肿与一颗或多颗未萌出的牙齿有关。短脑品种过多。受影响最大的是有58只狗（30％）的西藏猎犬和有48只狗（25％）的拳击手。最常见的受影响牙齿是下颌第一前磨牙，有238个（84％）囊肿。在总共279个囊肿中，208（75％）进行了组织病理学检查。检查的囊肿均无恶变。基于这208个囊肿,在狗群中发现有恶变的囊肿的可能性为0-1.4％（置信区间95％）。
