MICROORGANISMS IN HUMAN GI%GIVAL TISSUES,
Abstract
Gingival strip biopsies were taken from areas of obvious inflammation in 191 systemically healthy young adult males. For 72 of these subjects, a thorough oral prophylaxis was performed 24 hours prior to experimental participation. The remaining 119 subjects received no dental treatment of any type and served as controls. Serial sections were stained by four different methods: hematoxylin-eosin, the Brown and Brenn modification of the Gram stain, the Grocott modification of the Gomori's methenamine-silver nitrate technique and a combined Gram and Twort's staining technique formulated in this laboratory. Bacteria were found in the gingival tissues of approximately 10% of the nontreated subjects and 60% of those who received oral prophylaxis. These findings were held to be inconsistent with the premise of active bacterial invasion in gingival inflammation. (Author)
