Study summary

Periodontitis is an inflammatory disease that destroys tooth-supporting structures through oral bacterial plaque. ozone gel's act as an antimicrobial effect as an adjunct to conventional periodontal therapy (scaling and root planning). exposure of bacteria to ozone leads to the oxidation of the phospholipids and lipoproteins that comprise the bacterial cell membrane. Ozone gel has the potential to play an anti-inflammatory role in the treatment of periodontitis by monitoring both clinical and biological parameters.

Read the detailed description

Periodontitis is an inflammatory disease that destroys tooth-supporting structures through oral bacterial plaque. Scaling and root planning are considered the gold standard treatment for periodontal disease. Antiseptics represent an aid to the gold standard nonsurgical treatment of scaling and root planning (SRP) for periodontal disease. Adjuncts to scaling and root planning have been introduced as ozone gel. This gel represents both antimicrobial and beneficial effects while expressing safe cytocompatibility toward host tissues, which is progressively developing.

The study aims to determine ozone gel's antimicrobial effect as an adjunct to conventional periodontal therapy (scaling and root planning).

Material and Methods: Twenty-one patients with periodontitis were enrolled in this study. There were 58 periodontal pockets divided into two groups by a blinded split-mouth design. The control group had 28 periodontal pockets treated with scaling and root planning only, while the test group had 30 with scaling and root planning and ozone gel. Two gel applications were applied at baseline and one month after the treatment. Plaque index, bleeding on probing, probing pocket depth, and relative attachment level were recorded. Gingival crevicular fluid samples were collected from the pockets at each site for both groups at different time intervals. The GCF sample was transferred into Eppendorf tubes containing 1.5 ml of PBS buffer, and the samples were stored in a freezer at -40˚C.

Study arms

  • Experimental
    ozone gel with conventional scaling and root planning

    administered ozone gel in the probing pocket depth after scaling and root planning by a disposable plastic syringe with a blunt tip until the access ozone became out of the pocket. this procedure is made at baseline and in the first month. instructed the patient not to eat or drink for at least 30 minutes

    Drug: ozone gel

  • No intervention
    only conventional scaling and root planning

    only scaling and root planning without any intervention.

Interventions

  • Drugozone gel

    the activity of omega-3 in the ozone gel may be advantageous as a host-modulating agent in the supplemental treatment of periodontitis

    Time frame: baseline to one and three months

  4. level of platelet-activating factor in gingival crevicular fluid

    change in level of platelet-activating factor in gingival crevicular fluid (Used ELISA kit to measurement level of PAF in gingival crevicular fluid) by ozone gel as an adjunct to non-surgical treatment

    Time frame: baseline to one and three months
