Evaluation of the effect of correct flossing technique on periodontal clinical indicators
Design
Clinical trial with control group, 2 arm parallel group, single-blinded, randomized, on 100 patients, randomization was done with random numbers table.
Settings and conduct
Location: General Department, Faculty of Dentistry, University of Isfahan. How to do: Select 100 patients from dental school referrals. Method: Random allocation of patients to two groups of control and intervention using random numbers table. Blindness: The therapist is blinded because the therapist who performs the examination and scaling and root planning knows the patients only through random codes.
Participants/Inclusion and exclusion criteria
Inclusion criteria:
At least 20 existing teeth
People having calculus on their teeth
People completely healthy physically and mentally
People who are not used to using dental floss (use less than 2 times a week)
Having the necessary cooperation to observe health
Presence of Ramford's teeth or replacement teeth؛
Non-inclusion criteria:
Moderate to severe periodontitis
Deep caries, overhang and crown
Gingival recession
Pregnancy
Mouth breathing
People who are taking antibiotics or aspirin
People who have gingival hyperplasia
Intervention groups
Intervention group: After the initial sampling, index recording and scaling and root planning, people were taught the technique of brushing once a day by the Rolling method using a soft toothbrush along with the use of thin fluoridated dental floss once a day.
Control group: After the initial sampling, index recording and scaling and root planning, people were taught the technique of brushing once a day by the Rolling method using a soft toothbrush.
Main outcome variables
Clinical attachment level; Bleeding on marginal probing; Approximal Plaque Index; Calculus Surface Index; Probing depth index

Randomization (investigator's opinion)
Randomized
Randomization description
Participants selection in the study will be performed by simple randomization method, individually and with random number table tools.
In this way, a number will be written in front of the name of each person from the list of clients, then a table will be designed based on the sample size of the study, and we'll blindly touch a number of table numbers. The selected numbers will be included in the study if they are eligible after the examination. The intervention will be performed in a parallel design, and the choice of individuals' quadrant for Intervention or Control will be randomly performed with coin instruments.In such a way that for both quadrants which their numbers are accidentally put in the list, we drop a coin and if it's head for the first quadrant brushing instruction and for the second, brushing and flossing will be taught and vice versa if it is tails.
Blinding (investigator's opinion)
Single blinded
Blinding description
Participant: He knows about using a toothbrush with dental floss (intervention group) or using a toothbrush alone (control group).
Care provider and investigator: The person who records the indices and then does the scaling and root planning, is unaware of the names and groups of the participants and communicates with them only through the code assigned to each patient.
Data analyst: The data is evaluated numerically without specifying the name and the intervention or control group.
