What Researchers Did
Researchers evaluated the effect of hyperbaric oxygen therapy (HBO2) as an adjunct to scaling and root planing (SRP) in 20 patients with severe chronic periodontitis.
What They Found
The SRP + HBO2 group showed greater probing depth reduction and attachment gain than SRP alone three months post-treatment (p<0.001). The BANA test for bacterial presence was negative after one week only in the SRP + HBO2 group (p<0.05), though this difference was not significant after three months.
Canadian Relevance
This study is relevant to Canadian patients as periodontitis is a common oral health issue, and exploring adjunctive therapies like HBO2 could improve treatment outcomes.
Study Limitations
A limitation of this study is its small sample size of 20 patients, which may limit the generalizability of the findings.
