EFFECTS ON ORAL MICROBIOTA

Wolff, LF. et al: Phase Contrast Microscopic Evaluation of Subgingival Plaque in Combination with either Conventional or Antimicrobial Home Treatment with Periodontal Disease. J Perio Res 17: 537, 1982.

Purpose:

To compare the effect of phase contrast microscopy with topical antibacterial use of salt and peroxide to conventional home therapy for controlling the plaque and microflora and inflammation

Materials and Methods:

Group I consisted of patients that were given conventional oral hygiene with the use of floss and tooth brushing and toothpaste. Group II consisted of patients who were given Na Bicarbonate with 3% hydrogen Peroxide paste applied with a rubber point into the interproximal areas followed with tooth brushing x 1 min. Floss was also used and a gingival irrigation with 250 ml NaCl

1/2 of subjects was shown a video tape of their plaque. The patients had scaling and root planing (S/RP). Additional S/RP was performed if there was bleeding.

Additional S/RP in patients with plaque samples that were greater to equal to 15% spirochetes or motile bacteria.

Results:

Both groups showed drop in spirochetes and motile bacteria at 4 weeks and maintained though 8 weeks with motile bacteria and 16 weeks with spirochetes. The test group showed statistically significant decrease on the pocket depth > 4 mm vs. the conventional group. No statistically significant difference were seen at 8 and 16 weeks.

Conclusion:

Salt and peroxide regimen had a greater tendency to improve microbial and clinical criteria although these differences were not long lasting.
