About this study

Official title: Clinical and Biochemical Evaluation of Ozone Gel Versus Chlorohexidine Gel as an Adjunct to Non-Surgical Treatment of Stage II Periodontitis Grade B Among Smokers Patients

The aim of the present study is to evaluate and compare the clinical and biochemical outcomes of Ozoral® and High Cure® (chlorhexidine gel) as adjuncts to non-surgical periodontal therapy in smoker patients with Stage II Grade B periodontitis, using non-smoker patients with the same diagnosis as a comparative control group.

Read the detailed description

Periodontal diseases are disease processes involving the periodontium, a term used to describe the supportive apparatus surrounding a tooth, which includes the gingival tissue, alveolar bone, cementum, and periodontal ligament.

Chlorhexidine (CHX) has been widely used in dentistry as an antiplaque and antimicrobial agent due to its broad-spectrum activity against Gram-positive and Gram-negative bacteria, fungi, and some viruses. The antimicrobial action of chlorhexidine is mainly attributed to its ability to alter bacterial cell membrane permeability, resulting in leakage of intracellular components.

Ozone (O₃) is a highly reactive oxidizing agent that has gained increasing attention in medical and dental applications because of its potent antimicrobial, anti-inflammatory, and wound-healing properties. Ozone exerts its antimicrobial effect through oxidative damage to microbial cell walls and intracellular components, leading to rapid microbial inactivation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in gingival crevicular fluid tumor necrosis factor-alpha level

    Change from baseline in gingival crevicular fluid tumor necrosis factor-alpha (TNF-α) level will be measured using enzyme-linked immunosorbent assay (ELISA) at baseline, 15 days, and 6 months after treatment..

    Measured: 6 months after treatment

Secondary outcomes (5)
  1. Change in gingival crevicular fluid Interleukin-1 level

    Change from baseline in gingival crevicular fluid Interleukin-1(IL-1) evel will be measured using enzyme-linked immunosorbent assay (ELISA) at baseline, 15 days, and 6 months after treatment..

    Measured: 6 months after treatment

  2. Change in Plaque Index

    Change from baseline in Plaque Index, scored from 0 (no plaque) to 3 (abundant plaque accumulation). Lower scores indicate better oral hygiene. Changes will be compared among the three treatment groups.

    Measured: 6 months after treatment

  3. Change in Gingival Index

    Change from baseline in Gingival Index, scored from 0 (normal gingiva) to 3 (severe inflammation with a tendency toward spontaneous bleeding). Lower scores indicate less gingival inflammation. Changes will be compared among the three treatment groups.

    Measured: 6 months after treatment

  4. Change in Periodontal Probing Depth

    Change from baseline in periodontal probing depth will be measured in millimeters from the gingival margin to the base of the periodontal pocket using a periodontal probe. A reduction indicates improvement. Changes will be compared among the three treatment groups.

    Measured: 6 months after treatment

  5. Change in Clinical Attachment Level

    Change from baseline in clinical attachment level will be measured in millimeters from the cementoenamel junction to the base of the periodontal pocket using a periodontal probe. A reduction in this distance indicates clinical attachment gain. Changes will be compared among the three treatment groups.

    Measured: 6 months after treatment

Questions about this trial

What is this clinical trial studying?

A study testing Conventional scaling and root planing, Conventional scaling and root planing in addition to chlorhexidine gel and Conventional scaling and root planing in addition to ozone gel in people with Ozone Gel and Chlorohexidine Gel, run by October 6 University at 1 site in Egypt.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 6 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Sara A Agha, B.D.S (00201025536848, Ahmedagha55aa@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in gingival crevicular fluid tumor necrosis factor-alpha level (time frame: 6 months after treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Nov 2026.
