Remedies for dental diseases have been in use for as long as 4,000 years, and various materials and methods have been used over the millennia. Dentistry continues to change in response to changes in the age distribution, origins, financial means and health of the population, as well as to changes within the profession itself. The Canadian population is very unevenly distributed geographically and ethnically. Furthermore, it is aging rapidly and life expectancy is increasing. Although the average income of Canadians has increased, the increase was unevenly distributed, and the gap between rich and poor continues to expand. There has been a steady rise in the number of Canadians with dental insurance, although the proportion of the population with insurance varies from one province to another. Not surprisingly, people with dental insurance compared to those without are more frequent users of dental services. The rate of caries attack has diminished in industrialized countries, but people are keeping their teeth longer, so caries will remain a significant public health problem, particularly among elderly people. In addition, smoking tobacco is strongly associated with periodontal disease; thus, there should be more action within the dental community in support of smoking cessation programs. The composition of the dental care community is also changing. The ratios of dentists and dental hygienists to the population have increased, the services offered by dental technicians have expanded greatly, and the services offered by denturists have also increased as these services gain more widespread acceptance. Use of dental services in Canada remains reasonably broad; however, denture-wearers continue to regard uncomfortable dentures as a normal part of aging. The pattern of uneven distribution of disease and access to service remains the major challenge facing the dental profession.
治疗牙齿疾病的方法已经使用了长达4000年之久,在这几千年里人们使用了各种各样的材料和方法。牙科不断变化,以适应人口年龄分布、出身、经济状况和健康状况的变化,以及该行业自身的变化。加拿大人口在地理和种族上分布极不均衡。此外,人口正在迅速老龄化,预期寿命不断增加。尽管加拿大人的平均收入有所增加,但增长分布不均,贫富差距继续扩大。拥有牙科保险的加拿大人数量一直在稳步上升,不过各省拥有保险的人口比例各不相同。不出所料,与没有保险的人相比,有牙科保险的人更经常使用牙科服务。在工业化国家,龋齿发病率有所下降,但人们的牙齿保留时间更长,因此龋齿仍将是一个重大的公共卫生问题,尤其是在老年人当中。此外,吸烟与牙周病密切相关;因此,牙科界应采取更多行动支持戒烟计划。牙科护理群体的构成也在发生变化。牙医和口腔保健员与人口的比例有所增加,牙科技师提供的服务大幅扩展,随着这些服务得到更广泛的接受,假牙师提供的服务也有所增加。加拿大牙科服务的使用范围仍然相当广泛;然而,戴假牙者仍然将不舒服的假牙视为衰老的正常一部分。疾病分布不均和获得服务机会不均的模式仍然是牙科行业面临的主要挑战。
