作者检查了525人(男、女均有),年龄由15岁到45岁,其中265人牙周组织健康,210例有慢性卡他性龈炎,50例牙周炎。按 N·Brill 和 B·Krasse 的方法,用标准的大小为15×4 mm~2 的滤纸条收取龈液,作定量检查。检查前仔细清拭牙及牙龈,用棉块隔湿,晾干。将滤纸条的尖端放入龈沟口,而不要放到龈沟底。收取龈液的时间为3分钟。用测量滤纸条浸湿面积的方法确定龈液量。用0.2%茚三酮酒精液染色,可使浸湿面积更加明显。此外,还用天秤称量取液前、后滤纸条重量的方法确定龈液量。可以确定:慢性卡他性龈炎时,龈液量、龈沟龈袋和牙周袋的深度,炎症和卫生指数,均较牙周组织健康者增高。牙周炎时检查的各项参数比慢性卡他性龈炎和牙周组织健康者均有很大的意义。各组之间的差别是可信的(P<
The authors examined 525 people (both men and women), aged from 15 to 45 years of age, of which 265 healthy periodontal tissue, 210 patients with chronic catarrhal gingivitis, 50 cases of periodontitis. Gingival fluid was collected by a standard filter paper strip measuring 15 × 4 mm ~ 2 according to the method of N. Brill and B. Krasse for quantitative examination. Carefully clean the teeth and gums before check, use the cotton pad to separate wet and dry. Place the tip of the filter paper in the sulcus rather than at the gingival sulcus. The time to collect gingivitis is 3 minutes. The amount of gingival fluid is determined by measuring the wetted area of the filter paper. With 0.2% ninhydrin alcohol liquid staining, wetting area can be more obvious. In addition, the weight of the gingival fluid is also determined using a method in which the scales are weighed before and after the filter paper is weighed. It can be determined: when chronic catarrhal gingivitis, the amount of gingival fluid, gingival sulcular gingival pocket and periodontal pocket depth, inflammation and health index were higher than that of healthy periodontal tissue. Periodontal examination of the parameters than chronic catarrhal gingivitis and periodontal tissue are of great significance. The difference between the groups is credible (P <
