Forty pregnant women in each of three trimesters of pregnancy and forty nonpregnant women of comparable age, socioeconomic status and dietary habit have been examined to evaluate the gingival condition and the calculus and debris deposits. The study has shown that: There is a significant increase in the severity of gingivitis during pregnancy; The gingival changes progressively increase during the course of pregnancy; The gingival changes are more marked than the periodontal changes seen during pregnancy (increase in periodontal disease was seen in only a limited number of cases); There was an appreciable increase in the calculus and debris deposits in the pregnant as compared to the nonpregnant women; Increase in the calculus and debris deposits was apparent in all the trimesters of pregnancy; Gingival changes showed a greater correlation with the calculus and the debris index in the pregnant than in the nonpregnant women; The role of the irritant oral deposits either as a precipitating or perpetuating factor in the genesis of gingivitis during pregnancy can not be excluded.
对四十名处于孕期三个阶段的孕妇以及四十名年龄、社会经济地位和饮食习惯相近的非孕妇进行了检查，以评估牙龈状况以及牙结石和牙菌斑的沉积情况。研究表明：孕期牙龈炎的严重程度显著增加；孕期牙龈变化逐渐加剧；牙龈变化比孕期出现的牙周变化更为明显（仅在少数病例中观察到牙周疾病增加）；与非孕妇相比，孕妇的牙结石和牙菌斑沉积明显增加；在孕期的所有阶段，牙结石和牙菌斑沉积均有明显增加；与非孕妇相比，孕妇的牙龈变化与牙结石和牙菌斑指数的相关性更强；不能排除刺激性口腔沉积物在孕期牙龈炎发生过程中作为促发或持续因素的作用。
