Comparison of the Effectiveness of Interdental Aids in Reducing Plaque in Patient with Gingivitis

To determine the effect of interdental aids on plaque reduction in patients with gingivitis

Clinical trial, randomized, parallel, phase 2-3 on 54 patients

For 54 eligible patients referred to the Periodontics department of Yazd School of Dentistry who have gingivitis, a periodontal chart will be completed, including the following: probing depth, full mouth plaque index, and bleeding index will be recorded at the time of the examination. Then, all patients will receive Phase I Therapy, which includes scaling and oral hygiene instruction (OHI). Scaling will be performed using hand and ultrasonic instruments, based on the patient's treatment needs. OHI will be provided by the project's trained implementer, tailored to each group, and will include brushing twice a day and using an interdental cleaning device once a day for a duration of 4 weeks. The patients will be divided into 3 groups of 18 subjects each. Patients will be recalled after 4 weeks, and the variables of probing depth, full mouth plaque index, bleeding index, and patient-reported ease of use will be recorded. The data obtained from the 4-week examination will be compared with the initial examination data, and the data will be subjected to statistical analysis

inclusion: patient's age is between 18-50 years patient has generalized gingivitis no history of periodontal treatment in last 6 months No history of antibiotic consumption in the last 3 months exclusion: Failure of the patient to attend the follow-up session Identification of a systemic disease that affects periodontal conditions during the study

Group 1: Use a soft toothbrush and soft pick Group 2: Use a soft toothbrush and dental floss Group 3: Use a soft toothbrush and wooden toothpick

The randomization is performed using Simple Random Allocation. First, a sequence of random numbers from 1 to 54 is generated using the PASS 2021 software. The software output is a follow-up Excel file containing the numbers from 1 to 54 and a unique code for the study units. The patients who meet the criteria from numbers 1 to 54 are considered and allocated to one of the intervention groups (A, B, or C).

To ensure Blinding of the referrals (patients), we use the help of a third person who is unaware of the interventions, and the table is provided to them. When a study unit (patient) is referred and meets the criteria, the intervention group (A, B, or C) is asked from the third person by phone based on the patient's number, and the patient is assigned to one of the specified groups.
