October 20, 2018 updated by: Zekeriya Tasdemir, TC Erciyes University

The Effects of Ozone Therapy on Wound Healing After Gingivectomy Operations: a Controlled Clinical Study

the aim of present study was to evaluate effects of ozone therapy on wound healing after gingivectomy and gingivoplasty operations as a model of secondary wound healing.. Twenty three systemically healthy individuals participated in this study. Ozone was applied immediately after surgery, at 1st day and 3rd day after gingivectomy surgery. In the photographs of the wounds, the difference in color were evaluated and measurements were performed at the baseline, 3rd, 7th, 14th days after surgery.

Detailed Description

Although ozone therapy has often been tried in medical science and has become more popular due to its antimicrobial, biocompatibility and healing properties, the effects of ozone therapy on surgeries that heals with secondary intention were not studied. In the lights of these informations, the aim of present study was to evaluate effects of ozone therapy on wound healing after gingivectomy and gingivoplasty operations as a model of secondary wound healing. Twenty three systemically healthy individuals participated in this study. All periodontal examinations were performed by one experienced examiner and non-surgical periodontal treatment of the patients were performed within two weeks after initial examination by the same clinician.Gingivectomy and gingivoplasty operations were performed by another examiner who was unaware of the study protocol.After gingivectomy and gingivoplasty, right quadrants of the surgical areas were assigned to receive ozone therapy in all patients. Ozone therapy was also performed by an experienced periodontist. As placebo application, left quadrants received regular air from the ozone generator.Postoperative pain was assessed at 3rd, 7th, 14th days after surgery with a visual analog scale At baseline and 3rd, 7th, 14th days after surgery, surgical area was disclosed by a plaque disclosing solution to visualize the epithelization degree of the surgical areas. Solution provided a clear vision to distinguish normal gingiva from the areas in which the gingival epithelium is absent, abraded or lacking sufficient keratinization. In order to evaluate epithelization degree of the wounds, standardized photographs were taken from each patient.In the photographs of the wounds, the difference in color were evaluated and darkly stained areas were considered as lack of enough epithelization. These measurements were performed at the baseline, 3rd, 7th, 14th days after surgery. The determinations were done by a calibrated examiner who was blind to test and control sites

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
36

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
wound healing change
Time Frame: At baseline and 3rd, 7th, 14th days after surgery, wound healing evaluation were performed.
surgical area was disclosed by a plaque disclosing solution to visualize the epithelization degree of the surgical areas. Solution provided a clear vision to distinguish normal gingiva from the areas in which the gingival epithelium is absent, abraded or lacking sufficient keratinization. In order to evaluate epithelization degree of the wounds, standardized photographs were taken from each patient
At baseline and 3rd, 7th, 14th days after surgery, wound healing evaluation were performed.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Pain change
Time Frame: Postoperative pain was assessed at 3rd, 7th, 14th days after surgery
Visual analog scale was used for the pain assesment. On the scale, the left end of the graphic represented the absence of pain (score 0) and the right end represented the most severe pain (score 10).
Postoperative pain was assessed at 3rd, 7th, 14th days after surgery
