Oral and pharyngeal cancers are largely preventable and can be successfully treated when diagnosed at an early stage. Dentists in British Columbia and Nova Scotia were surveyed regarding their knowledge and opinions about oral and pharyngeal cancer. In February 1998 a pretested 41-item survey was mailed to a random sample of dentists in British Columbia and the population of dentists in Nova Scotia. A reminder postcard and one additional mailing were sent to nonrespondents. Of the 670 dentists supplying usable responses (response rate 55.2%) only 56.7% agreed that their knowledge of the subject was current. Most dentists correctly identified tobacco use (99.4%) and alcohol use (90.4%) as risk factors, but fewer correctly identified factors such as the use of spicy foods (57.0%) and poor oral hygiene (46.3%) as not being risk factors. Only 42.5% identified both erythroplakia and leukoplakia, in that order, as the conditions most likely associated with oral cancer. Indices of risk and diagnostic knowledge were constructed by summing the number of correct responses to items in each domain. On 16 risk factors the mean correct score was 9.2, and on 14 diagnostic procedures the mean correct score was 10.0. Only 38.5% of dentists had consistent levels of knowledge on both indices. Differences between the provinces were statistically significant (p < 0.01) for only 2 knowledge items. About three-quarters of all dentists (77.0%) were interested in taking continuing education courses. Dentists in British Columbia and Nova Scotia could benefit from undergraduate and continuing education courses to increase their knowledge of risk and diagnostic factors for oral cancer.
口腔癌和咽癌在很大程度上是可以预防的，若能早期诊断，也可成功治愈。我们对不列颠哥伦比亚省和新斯科舍省的牙医进行了调查，了解他们对口腔癌和咽癌的知识及看法。1998年2月，一份经过预测试的包含41个项目的调查问卷被邮寄给不列颠哥伦比亚省的随机抽取的牙医样本以及新斯科舍省的全体牙医。给未回复者寄了一张提醒明信片和再次邮寄了问卷。在提供可用回复的670名牙医中（回复率55.2%），只有56.7%的人认为他们对该主题的了解是最新的。大多数牙医正确地将吸烟（99.4%）和饮酒（90.4%）识别为风险因素，但较少有人正确地将食用辛辣食物（57.0%）和口腔卫生差（46.3%）等因素识别为非风险因素。只有42.5%的人依次将红斑和白斑识别为最可能与口腔癌相关的病症。通过对每个领域项目的正确回复数量求和构建风险指数和诊断知识指数。在16个风险因素方面，平均正确得分是9.2，在14个诊断程序方面，平均正确得分是10.0。只有38.5%的牙医在这两个指数上的知识水平一致。两省之间只有2个知识项目存在统计学显著差异（p < 0.01）。大约四分之三的牙医（77.0%）有兴趣参加继续教育课程。不列颠哥伦比亚省和新斯科舍省的牙医可以从本科和继续教育课程中受益，以增加他们对口腔癌风险和诊断因素的了解。
