Clinical Trial Summary

This randomized clinical trial study aims to investigate the impact of home-based differential learning on tooth brushing, in particular on the reduction of plaque and maintenance of gingival health in children aged 3 to 8 years, compared to the habitual tooth brushing and instruction/demonstration tooth brushing learning method.


Description:

This two-parallel arm single-blind randomized controlled clinical trial will be undertaken at the Department of Preventive and Pediatric Dentistry at the University of Greifswald. The examination of the patient will be undertaken in a dental chair set up using standard infection control guidelines for a dental examination used at the department. The allocation of the patients to the two groups will be done through asking the patients to pick up an envelope randomly from a box which contains the information and explanation for home brushing. In the first visit, the baseline dental examination and patient acceptance survey will be done to comprehensively assess each participant's oral health status, their oral hygiene status, caries experience and periodontal condition will be recorded. To assess oral hygiene status we will use plaque index (PI) (Quigley Hein, 1972) on a scale of 0 to 5. Dental caries experience will be recorded by counting the numbers of teeth that are decayed (dt/DT), missing due to caries (mt/MT), and filled (ft/FT) to generate a dmft/DMFT score. Periodontal condition will be recorded using the papillary bleeding index Index (PBI) on a scale of 0 to 4. One trained and calibrated examiner will perform the clinical examinations. The study and its objectives will be explained to the patients. For the control group, regular instructions and advice will be provided as in any regular prophylaxis session. For the test group, the exercises and movements to be performed when brushing the teeth will be explained. The patients in both groups will be also provided with explanation leaflet with the exercises and a free toothbrush. There will be no restriction on the type of the fluoridated toothpaste. The training sheet will include the following exercises: - Tooth brushing while lying down. - Tooth brushing with one eye covered (i.e. with the hand). - Tooth brushing wearing large gloves. - Tooth brushing with the non-dominant hand. - Tooth brushing using both hands. - Different sequence of tooth brushing compared to the practical demonstration (i.e. starting with cleaning the lingual surface instead of occlusal surface). - Tooth brushing while both eyes are closed. - Tooth brushing with an obstruction on the elbow of the dominant hand (i.e. wraps a piece of cloth/ scarf around the elbow). - Tooth brushing while watching 3-5 minutes video (i.e. using YouTube). The parent/ child will be requested to perform each exercise one time a day for 3 days in a row before moving to the next exercise. All parent/ child will be asked to do the exercises in the same sequence. After completing the exercise for each day, children will be asked to put a sticker in the calendar table, which will be provided to them as a motivation to perform the exercises. There will be 2 follow-ups; the first follow-up after one month will include dental re-examination, using the same methods and criteria as the baseline examination as well as a questionnaire for the parents to assess their experience and acceptance of the used method. The second follow-up will be after 3 months and it will include dental re-examination, using the same methods and criteria as the baseline examination.
