近40年来,为评估牙龈炎的程度与范围,形成了多种牙龈记分指数,它们取决于术者的熟练程度、知觉及对牙龈状态的判断,因而具有一定的主观性。其中由L(?)e 和Silness 提出的牙龈指数(GI)获得广泛的承认与应用,但都需通过探查牙龈出血情况记分。本文作者提出一种改良的牙龈指数记分法(MGI)——非侵入性视觉观测法,同样能反映牙龈的炎症状态,且避免了一些人为因素。材料与方法对象;患有Ⅰ或Ⅱ度牙周疾病的99位18岁～55岁的志愿者,无肉眼可见的口腔病变,未使用过抗菌、抗炎治疗者。口内有20颗自然牙,不包括大部龋坏、修复体、第三磨牙。
In the past 40 years, in order to evaluate the extent and extent of gingivitis, a variety of gingival scoring indices have been formed, which depend on the proficiency, perception and judgment of the gingival condition of the surgeon, and thus have a certain subjectivity. Gingival index (GI) proposed by L (?) E and Silness has been widely recognized and applied, but it needs to be scored by examining the bleeding of gums. The authors propose a modified gingival index scoring method (MGI) - a noninvasive visual observation that also reflects the gingival inflammatory state and avoids some human factors. MATERIALS AND METHODS Subjects: Ninety-nine volunteers aged 18-55 with periodontal disease of grade I or II had no visible pathological changes of the oral cavity and no antibacterial or anti-inflammatory treatment was used. Mouth with 20 natural teeth, does not include most of the caries, prosthesis, the third molar.
