过去认为齿龈内阿米巴为非病原性原虫。而我们近年的调查研究中发现它常与牙周病共存,杀原虫药物治疗后有显效。 材料与方法一、检查对象 随机接诊口腔科初诊病人,作临床诊断的同时取样作镜检。二、方法将取得的牙龈袋(沟)内含物作生理盐水涂片,记录阿米巴感染与否及感染度。低倍镜(100×)下1～3视野发现阿米巴者为+++,4～5视野发现者为++,6视野以上发现者为+。涂片(范围为18mm~2)以火焰固定,革兰氏染色后任取4个视野(400×),每视野取一象限,四象限微生物数作为标本微生物数域指标。
In the past that the gingival amoeba non-pathogenic protozoa. In recent years, we found that it often coexist with periodontal disease investigation and investigation, killing the parasite drug treatment after markedly effective. Materials and methods First, the randomized patients admitted to the first visit to the Department of Stomatology, for clinical diagnosis of simultaneous sampling for microscopic examination. Second, the method will be obtained gingival pocket (groove) contents of saline as a smear record of amoeba infection or not and the degree of infection. Low magnification (100 ×) 1 to 3 field found amoeba was +++, 4 ~ 5 field of vision was ++, 6 field of vision was + above. The smear (range 18mm ~ 2) was fixed by flame. After Gram staining, four fields (400 ×) were taken and one quadrant per field of view. The four-quadrant number of microorganisms was taken as the index of the number of microorganisms in the specimen.
