The Effect of Female Sex Hormones on Subgingival Plaque

Journal of Periodontology (1981)

James R. Jensen W. F. Liljemark Cynthia G. Bloomquist

T he periodontal status of three groups of women; pregnant, taking oral contraceptives, and nonpregnant, were evaluated clinically and microbiologically for changes in their gingiva and any corresponding changes in the subgingival microbial plaque, specifically the percentage of Fusobacterium species and Bacteroides species. Overall, the women had relatively good gingival health. However, statistically significant increased scores were observed in the Gingival Index and the gingival crevicular fluid flow in the pregnant group compared with the nonpregnant group. The most dramatic microbial changes were the increased proportions of Bacteroides species both in the pregnant group and the group taking oral contraceptives over the nonpregnant group. Increased female sex hormones substituting for the napthaquinone requirement of certain Bacteroides were most likely responsible for this increase. No statistically significant clinical difference was noted between the group taking oral contraceptives and the nonpregnant group, although a 16‐fold increase in Bacteroides species was observed in the group taking oral contraceptives.

Salt and Peroxide Compared with Conventional Oral Hygiene: II. Microbial Results

Journal of Periodontology (1987)

Larry F. Wolff Bruce Lee Pihlstrom M. Bashar Bakdash Erwin M. Schaffer James R. Jensen

This study was designed to investigate the effect of conventional oral hygiene ( n = 116 subjects) versus a salt and peroxide oral hygiene regimen ( n = 115 subjects) on subgingival microorganisms. Subgingival plaque for microscopic evaluation was obtained from eight index tooth sites in each of 231 adult subjects. Microbial forms were microscopically identified at baseline, 8, 16, and 24 months. For both oral hygiene groups, cocci were increased ( P < 0.05) and motile rods were decreased ( P < 0.05) at 8 months and returned to baseline by 16 months. Spirochetes were decreased ( P < 0.05) and remained low through 24 months in both oral hygiene groups. The frequency of agreement between clinical (bleeding) and microbial (>15% spirochetes or motile rods or >20% spirochetes + motile rods) criteria for instrumentation was 59.8%. It was also found that fewer total instrumentations for test subjects were observed when microbiological criteria were used as compared with clinical criteria. The greater number of instrumentations based on clinical criteria was highly significant ( P < 0.001). A significant change in microbial signs associated with periodontal disease may be obtained with either a conventional oral hygiene or a salt and peroxide oral hygiene home care regimen.
