During 21 days of abolished oral hygiene and developing gingivitis the microbial changes were studied in buccal and interdental sites. The subgingival plaque of 6 dental students was analyzed by darkfield microscopy. The microbiota found in interdental sulci showed a higher complexity than that of buccal sites. Buccally and interdentally there was a significant increase in the total number of microorganisms between days 0 and 21. Yet, the development of gingivitis was slower in the buccal than in the interproximal sites. For all bacteria, but specially for more disease-associated morphotypes the accumulation rate was higher interdentally than buccally.
在为期21天的口腔卫生被废止并发生牙龈炎的过程中，对颊部和牙间隙部位的微生物变化进行了研究。通过暗视野显微镜对6名牙科学生的龈下菌斑进行了分析。在牙间隙沟中发现的微生物群比颊部部位的微生物群具有更高的复杂性。在第0天和第21天之间，颊部和牙间隙部位的微生物总数均显著增加。然而，颊部牙龈炎的发展比邻面部位要慢。对于所有细菌，尤其是与疾病关联度更高的形态类型，牙间隙部位的累积率高于颊部。
