COMORAL® the Oral Irrigation Unit Clinical Trial (COMORAL)

August 26, 2021 updated by: Reuben Kim, DDS, PhD, University of California, Los Angeles

Effect of COMORAL® the Oral Irrigation Unit in Preventing Gingivitis and Plaque Formation

This is a clinical study to evaluate the safety and effectiveness of COMORAL®, the intraoral water-spraying cleaning device that is developed to remove plaque around teeth in the oral cavity. To do so, 42 healthy subjects, 21 control and 21 experimental, will be recruited.

To establish the baseline, all subjects will receive dental hygiene service. After 2 weeks, patients will be randomly assigned to either control or intervention group (21 individuals each). Both groups will be asked to brush their teeth once a day but without dental floss, mouth rinse, and gum chewing, throughout the 4 weeks of study period. During the study period, the experimental group will receive COMORAL® treatment three times a day every day for 4 weeks except Saturday and Sunday.

Subjects will get evaluated for the oral status(PI, BOP, GI, PD, GR, CAL) and the status of periopathogens on visit 1, visit 2 and visit 3.

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

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

Detailed Description

This is a randomized, open-labeled, single-centered clinical study to evaluate COMORAL® the intraoral water-spraying cleaning device that is developed to remove plaque around teeth in the oral cavity. The purpose of this clinical study is to evaluate the safety and effectiveness of COMORAL® the oral irrigation unit in preventing gingivitis and plaque formation in adult patients.

42 patients between 18 to 25 years old who have a periodontal probing depth of 3 mm or less will be recruited. To establish the baseline, all the patients will receive dental hygiene service.

After 2 weeks (Visit 1), patients will be randomly assigned to either control or intervention group (21 individuals each). They will be asked to do the following instruction; Control group (21 total) - The individuals in the control group will be asked to brush their teeth once a day at home throughout the 4 weeks of study period. They will be asked not to use the supplementary oral hygiene products including mouth rinse, dental floss and chewing gum.

Experimental/Intervention group (21 total) - The individuals in this group will be asked to brush their teeth once a day at home throughout the 4 weeks of study period. They will be asked not to use the supplementary oral hygiene products including mouth rinse, dental floss and chewing gum. Instead, they will be asked to come to the clinic to use COMORAL® three times a day, every day except Saturday and Sunday.

Subjects in both groups will be evaluated for clinical indices (PI, BOP, GI, PD, GR, CAL) and the status of periopathogens on visit 1(baseline, visit 2(after 2 weeks), and visit 3(after 4 weeks). To measure the status of periopathogens, 3ml of saliva will be collected from each subject.

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.

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

18 years to 25 years (Adult)

Accepts Healthy Volunteers
