什麽叫幹槽癥

 什麽叫幹槽癥?什麽叫幹槽症幹槽症又稱牙槽骨炎、纖維蛋白溶解性牙槽炎。它的病理過程是在拔牙後2~第3天牙槽窩內血塊分解脫落、感染、硬骨板壞死,有時也可出現碎小的死骨。臨床表現是拔牙後2~第3天開始自發疼痛,並向耳颞部或前牙放射,醫生檢查時發現拔牙窩內血凝塊脫落,骨壁暴露,並呈灰白色,有惡臭,探針碰到骨壁時十分疼痛,如果不及時治療,病程可持續半個月或更長。幹槽症可以發生在任何拔牙窩,但是以下颌阻生智齒拔除後發生率最高,可達10%~第30%。幹槽症發生的原因尚不十分明確,現普遍認爲與創傷、感染和拔牙窩大有關。幹槽症的治療以局部處理爲主,口服消炎藥物療效不滿意,所以需要到醫院由醫生治療。方法是:第一次治療須在局麻下徹底刮牙槽窩,然後用過氧化氫液棉球、鹽水棉球反複擦拭牙槽窩,填塞蘸有丁香油或地卡因的碘仿紗條,當天就可以止痛。過3天再換一次藥,這次不要再刮牙槽窩了,第二次換藥後如果不痛了,就可以不用再換藥,讓紗條自行脫落。
