Comparison of the effectiveness of two oral hygiene educational methods, oral and using video, in patients with gingivitis in terms of changes in plaque index and gingival index, a randomized clinical trial

Comparison of the effect of two oral health education methods, oral and using video, in terms of changes in plaque index and gum index in patients with gum disease.

Clinical trial with control group, with parallel groups, double-blind, randomized. Randomization is done by an independent person using the sealed envelope program to allocate people equally and randomly in the control and test groups.

All the patients referred to the International School of Dentistry, Tehran. Information on plaque index and gingival index of patients before and after phase one periodontal treatment is recorded. People are blindly and randomly placed into two control and test groups. In the control group, oral hygiene education is given face-to-face, which includes demonstration, and in the test group, oral hygiene education is done using video, which is taught the same content in both test and control groups. In the 4-week follow-up, in order to blind the results (outcome blinding), one of the professors who did not monitor the treatment stages of the patient, compares the relevant treatment group in terms of the effectiveness of the educational method.

Eligibility criteria - Minimum average PI and GI with a score of two - Adults over 18 years old - Absence of systemic disease - Presence of at least 20 permanent teeth exclusion criteria - Pregnancy and smoking - Physical and mental problems

In the control group, oral hygiene education is given face-to-face, which includes demonstrations, and in the test group, oral hygiene education is done using video. In both the test and control groups, the same content is taught.

Plaque Index = Quigley Hein Plaque Index gingival index=Silness and loe gingival index Examining these two indicators in health education by video and oral methods

People are blinded and randomized in two control and test groups. Matching of two control and test groups is done by frequency matching method, also regression model is used to eliminate the effect of potential confounding variables in the study. Blinding is done with the help of pre-prepared letters. Each letter determines an oral teaching method (control group) or with the help of video (test group). Sequence generation This process is done by an independent person using the sealed envelope program to allocate people equally and randomly in control and test groups. Concealment The obtained codes are printed on a paper inside the letter and arranged in a box in the periodontics department according to the same algorithm (without the students and professors knowing the order). Letters are kept separately after use.

All data can be shared, such as education, age, gender, amount of plaque and gingivitis.

The beginning of the access period is 3 months after the end of the results and conclusions.

The data will be applicable and accessible to all dentists.
