Abstract: This paper reports the effects of Hyperbaric Oxygen (HBO2) in a controlled study of periodontitis in 24 patients. The patients received either HBO2 or no HBO2, and study teeth were divided into 4 groups based on treatment: 1-HBO2 therapy, 2-HBO2 + scaling, 3-scaling, 4-control. We measured indices of periodontal disease and gingival blood flow (GBF). The microorganisms in a periodontal pocket were stained and the percentage of straight rods (Rods), curved rods (Cur), fusiforms (Fusi) and spirochetes (Spiro) were observed. The numbers of anaerobic organisms were measured by routine anaerobic culture. Highly significant differences in Gingival Indices (GI), Sulcus Bleeding Indices (SBI), Probing Depth (PD), Attachment Loss (AL), Plaque Index (PLI), and GBF were seen in the HBO2, the HBO2 + Scaling and the Scaling Groups compared to the Control Group (P < 0.01). The number of subgingival anaerobes as well as the number of Rods, Cur, Fusi, and Spiro were reduced markedly in these three treatment groups. Statistically greater differences in clinical indices, GBF, subgingival anaerobe number and number of Rods, Cur, Fusi and Spiro were found by comparison of HBO2 + Scaling and HBO2 Groups, as well as between the HBO2 + Scaling and Scaling Groups, but no significant differences were observed in GI, SBI, PD, or AL between the HBO2 and Scaling Groups. In conclusion, HBO2 had beneficial therapeutic effects on severe periodontitis. HBO2 therapy combined with scaling and root planing was the most beneficial in the treatment of periodontitis. Clinical follow-up suggests that this treatment effect could last more than 1 year.
