Brief Summary:
Evaluation of the clinical effect of hyperbaric oxygen therapy (HBOT) adjunctively to scaling and root planing (SRP) in the treatment of severe case of chronic periodontitis.

Condition or disease Intervention/treatment Phase
Periodontal Disease Other: oxygen Other: other Not Applicable

Detailed Description:

Materials and Methods: In 20 patients diagnosed with severe generalized chronic periodontitis (pockets>7mm) with bleeding on probing, SRP was rendered in all pockets. Additionally, five consecutive hyperbaric sessions were administered in 10 patients after random allocation (SRP+HBOT). Clinical parameters were assessed at baseline up to 6 months: plaque index (PI), bleeding on probing, probing depth, clinical attachment level and BANA test.

Results: SRP+HBOT resulted in greater probing reduction and attachment gain than SRP alone 3 months after treatment (p<0.001). The BANA test was negative after 1 week only for sites in the SRP+HBOT group (p<0.05). However SRP+HBOT failed to show a significant difference from SRP group after 3 months were all BANA sites became negative (p>0.05).

Conclusion: These preliminary data suggest that hyperbaric oxygen therapy had a short-term beneficial effect on pocket reduction and bacterial elimination, and may be considered a potential therapy option to improve the clinical outcomes of scaling in severe cases of chronic periodontitis.

Ages Eligible for Study:   30 Years to 65 Years   (Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   Yes

Inclusion criteria:

  • This preliminary (pilot) study was designed with twenty subjects (12 men, 8 women, mean age 37.3 years) selected from a pool of 360 patients referred to the Periodontal Clinic of the School of Dentistry at Bahian Science Foundation (FBDC, Bahia, Brazil).
  • The patients had an initial diagnosis of severe generalized chronic periodontitis (AAP 1999).

Exclusion criteria:

  • Patients were excluded according to the following criteria:

    • smoking
    • pregnancy or lactation
    • antibiotics or periodontal treatment within the last 6 months
    • a diagnosis of aggressive periodontitis
    • trauma from occlusion or endodontic lesions
  • According to an accurate clinical examination performed by a hyperbaric medical doctor (MD), the HBOT contra-indications (Iazzeti & Mantovani 1998) served as exclusion criteria.
  • The only absolute contraindication to hyperbaric oxygen therapy was from patients with untreated pneumothorax
  • Relative contraindications were considered:

    • upper respiratory infections
    • high fevers
    • emphysema with CO2 retention
    • historic of thoracic surgery
    • malignant disease and middle ear barotrauma
  • Patients taking or have recently taken the following drugs:

    • doxorubicin (Adriamycin®)
    • disulfiram (Antabuse®)
    • Cis-platinum and mafenide acetate (Sulfamylon®).
