The prevalence and features of 3 types of exostoses commonly encountered during periodontal surgery were studied in a sample of 328 modern American skulls drawn from the collection at the American Museum of Natural History. Measurements were made of the height, width, and breadth of exostoses. The relationship to teeth or other skeletal structures was also recorded. Palatal tubercles were observed in 56% of all skulls (69% of all dentate skulls), with higher prevalences among males and African-Americans. Palatal tubercles were commonly associated with second and third molars, and were usually directly lateral to and a mean of 11.4 mm from the greater palatine foramen. Mandibular tori were observed in 27% of all skulls (42% of dentate skulls), with higher prevalences seen among African-Americans and males. The importance of these findings relates to the frequent need for exostosis removal to permit proper flap adaptation, especially in the posterior maxilla, and to the potential use of the mandibular and palatal tori as sources of autogenous cortical bone.
在从美国自然历史博物馆馆藏中抽取的328个现代美国头骨样本中，研究了牙周手术中常见的3种外生骨疣的患病率及特征。对头骨外生骨疣的高度、宽度和厚度进行了测量，并记录了其与牙齿或其他骨骼结构的关系。在所有头骨中，56%（所有有牙头骨的69%）观察到腭隆突，男性和非裔美国人的患病率更高。腭隆突通常与第二和第三磨牙相关，通常位于腭大孔的直接外侧，距腭大孔平均11.4毫米。在所有头骨中，27%（有牙头骨的42%）观察到下颌隆突，非裔美国人和男性的患病率更高。这些发现的重要性在于，经常需要去除外生骨疣以确保皮瓣适当贴合，尤其是在上颌后部，以及下颌和腭隆突作为自体皮质骨来源的潜在用途。
