核潜艇艇员长航前后牙周临床指数和牙周可疑病原菌的变化

目的 探讨核潜艇艇员长航前后牙周状况和牙周可疑病原菌的变化.方法 选择78名核潜艇艇员,于长航前后分别检查16、41牙位的菌斑指数、牙龈指数、探诊深度、探诊出血,并在颊侧龈沟底部采集龈下菌斑样本,采用PCR方法分别检测7种牙周可疑病原菌,比较枪出率.结果 与长航前相比,长航后菌斑指数(PI)、牙龈指数(GI)、探诊出血(BOP)虽有上升但差异无统计学意义(P＞0.05)；PD升高具统计学意义(P＜0.05).长航后牙龈卟啉单胞菌、福赛坦氏菌、中间普氏菌、齿垢密螺旋体的检出率有增加(P＜0.05).结论 核潜艇艇员长航可引起龈下菌斑中牙周可疑病原菌增加.

Clinical periodontal indexes and suspicious periodontal pathogens in officers and men of nuclear submarine before and after a long voyage

Objective To study the change of clinical periodontal indexes and suspicious pathogens in officers and men of nuclear submarine before and after a long voyage.Methods Seventy-eight officers and men of nuclear submarine were enrolled in this study.Dental plaque index(PI),gingival index(GI),probing depth(PD) and bleeding on probing(BOP) were detected in 16 and 41 teeth.Subgingival plaque samples were collected from the buccal gingival groove of the right mandibular incisor and the right maxillary first molar.Seven suspicious periodontal pathogens were detected by PCR and their detection rates were compared.Results The PI,GI and BOP officers and men of nuclear submarine were higher after a long voyage than before it but no significant difference was observed in them(P>0.05).The PD was significantly higher after a long voyage than before it(P<0.05).The detection rate of P.gingivalis,Tforsythia,Pintermedia,and Tdenticola was higher after a long voyage than before it(P<0.05).Conclusion The number of suspicious pathogens increases in subgingival plaques of officers and men of nuclear submarine after a long voyage.
