流行病学研究表明:牙龈炎是流行性极高的疾病。在澳大利亚和中国的情况也是如此。在澳大利亚,牙科医生与总人口的比例为1:2100。即便这样也不可能使每个患有牙龈炎的人得到治疗。在中国,牙科医生与人口的比例为1:250000,要治疗每个龈炎患者就更不可能了。因此,需要适当集中地使用牙科医生。牙科医生的责任可能就在于:选择最可能发生破坏性牙周病的患者,提供预防或早期治疗措施。这一部分只占人群中较小的比例。许多国家是有人力给这部分人作预防和治疗工作的。为了能恰当地选择病人,应很好地理解整个疾病过程。这主要包括:①牙菌斑的致病力;②局部免疫反应;③个体对疾病的易感性。
Epidemiological studies have shown that: Gingivitis is a highly epidemic disease. The same is true in Australia and China. In Australia, the ratio of dentists to the total population is 1: 2100. Even then it is impossible for everyone with gingivitis to get treated. In China, the dentist to population ratio is 1: 250,000, and it is even more impossible to treat every gingivitis patient. Therefore, dentists need to be used appropriately and centrally. The dentist's responsibility may lie in selecting the patient who is most likely to have devastating periodontal disease and providing prevention or early treatment. This part accounts for only a small proportion of the population. Many countries have manpower to prevent and treat this group of people. In order to properly select the patient, the entire disease process should be well understood. This includes: ① plaque virulence; ② local immune response; ③ individual susceptibility to disease.
