目的：了解兰州地区人群的牙周健康状况，检测牙周健康者及牙周疾病患者口腔唾液中牙龈卟啉单胞菌（Porphyromonas gingivalis，Pg）的阳性率，为兰州地区人群防治牙周疾病提供科学依据。方法收集942例唾液标本，采用常规厌氧培养法，挑取产黑色素菌落进行革兰染色与生化鉴定。结果兰州地区人群牙周疾病患病率为78．45％，男女性别间差异无统计学意义（P ＝0．655）；农村人群（53．45％）高于城市人群（46．55％），差异有统计学意义（P＝0．029）；各年龄段差异有显著的统计学意义（P ＝0．001），随年龄增长患病率呈增长趋势。兰州地区人群唾液中 Pg 总阳性率为71．23％，牙周疾病组（82．22％）显著高于牙周健康组（27．57％），差异有显著的统计学意义（P ＝0．000）。结论兰州地区人群牙周健康状况与生活环境、年龄、性别有关；在不同的牙周健康状况人群中牙龈卟啉单胞菌的分布不同。

Objective To evaluate a healthy condition for pericementum and determine porphyromonas gingivalis (Pg) prevalence in saliva in populations in Lanzhou area,and provide a scientific basis in prevention of pericementum diseases. Methods Saliva samples were collected from 942 residents in Lanzhou.After anaerobic cultivation,the black-pigmented colonies were selected and identified by Gram staining and biochemical analysis.Results The incidence for pericenmen-tum was 78.45%.There were no statistical difference in the prevalence rate between male and female individuals (P =0.655).The incidence for residents living in urban area was 46.55%,which was less than that for residents living in rural area (53.45%,),with a statistical difference (P =0.029)in both populations.The prevalence rate of pericementum deseases was a statistically significant difference (P =0.001)in different age stages along with age growing.The positive rate for Pg in saliva from populations in Lanzhou was 71.23%.Pg was detected in 83.22% patients suffered from perice-mentum diseases more than in 27.57% from the healthy subjects,there was a statistically significant defference (P =0.000)in both of them.Conclusion The healthy conditions for pericementum are associated with age,gender,and living environment in populations in Lanzhou area and Pg distributions are different in different healthy conditions related to pericementum in the populations.
