Effectiveness of Enoxolone on Oral Conditions of Patients With Periodontal Surgery (Enoxolone)

August 4, 2023 updated by: Kaohsiung Medical University Chung-Ho Memorial Hospital
Abstract Aim:The Enoxolone (18β-glycyrrhetinic acid; BGA) is a bioactive compound in licorice that exhibits potential anti-ulcer, anti-inflammatory, and anti-microbial activities, relieve oral ulcers, pain, improve gingivitis and dental plaque from past relevant experimental studies,but few clinical trials have evaluated its clinical effectiveness. Therefore, the purpose of this study is to evaluate the effectiveness of Enoxolone on oral conditions of patients with periodontal surgery. Methods:This study is a randomized controlled trial. Patients with severe chronic periodontitis who needed to accept periodontal surgery were randomly assigned to two groups, the experimental group was Enoxolone toothpaste, and the control group for Sensodyne toothpaste. After the operation, toothpaste was used three times a day to clean the mouth for 12 weeks . Clinical evaluation was using the patient-reported pain score, painkillers, wound healing index (complete epithelization and color matching score), periodontal pocket depth, gingiva index, plaque index and were recorded before operation and 1st, 2nd, 3rd, 4th, 8th, 12th week after surgery. Data set performs repeated-measures for the change in mean differences by using the two-tailed independent t tests and generalized linear model.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

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. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Enoxolone is a toothpaste containing 18β-glycyrrhetinic acid (BGA). In this study, the experimental group used Enoxolone toothpaste, and the control group did not contain BGA toothpaste (Sensodyne), which is used for oral cleaning of patients after periodontal disease surgery. The absorption rate is very low, and it will not cause any interaction with western medicine.

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.

Experimental: Enoxolone
The experimental group (N=15) returned home after the operation and used BGA toothpaste (Enoxolone) three times a day for oral cleaning for 12 weeks.
Other: Enoxolone
The experimental group returned home after the operation and used glycyrrhetinic acid toothpaste three times a day for oral cleaning.After the operation, toothpaste was used three times a day to clean the mouth for 12 weeks . Clinical evaluation was using the patient-reported pain score, painkillers, wound healing index (complete epithelization and color matching score), periodontal pocket depth, gingiva index, plaque index and were recorded before operation and 1st, 2nd, 3rd, 4th, 8th, 12th week after surgery. The control group used ordinary toothpaste for oral cleaning, and the rest of the research time, measurement time and measurement results were the same as the experimental group. During the study period, we will continue to monitor whether there is any adverse reaction, and if any adverse reaction occurs, the trial will be stopped.
