發(fā)布時間:2018-08-27 11:59
【摘要】:目的通過比較不同類型的種植體周圍菌群的分布情況,探討不同種植體類型在健康和炎癥狀態(tài)下齦下菌群分布是否不同。方法選取40名患者的80枚種植體牙作為研究對象,其中FrialitⅡ種植體40例;Hoist種植體40例。采用自身對照配對設(shè)計,將種植體分為FrialitⅡ健康組(一組),Hoist健康組(二組),FrialitⅡ炎癥組(三組)和Hoist炎癥組(四組);比較兩種種植體在健康狀態(tài)下和炎癥狀態(tài)下牙周菌群的檢出及分布情況。結(jié)果兩種種植體炎癥組的PD值均高于健康組,差異有統(tǒng)計學(xué)意義(P0.05);健康組均以革蘭陽性兼性厭氧的口腔鏈球菌和放線菌屬為優(yōu)勢菌:分別占52.25%、16.45%、51.35%和17.46%;兩種種植體炎癥組均以革蘭陰性厭氧桿菌和革蘭陽性兼性厭氧口腔鏈球菌為優(yōu)勢菌:分別占41.44%、32.07%、45.69%和28.53%。健康組分別與種植體炎癥組相比,細(xì)菌構(gòu)成比差異有統(tǒng)計學(xué)意義(P0.05)。結(jié)論在健康或者炎癥狀態(tài)下,FrialitⅡ和Hoist種植體齦下菌群的構(gòu)成相似,不能認(rèn)為種植體周圍齦下菌群的構(gòu)成與種植體類型有關(guān)。
