The participants are randomly distributed into two groups where Group I receive only standard oral hygiene instruction and Group II receive reminders via Brush DJ mobile application in addition to standard oral hygiene instructions. For the standard oral hygiene protocol received by participants of both groups, all of them are instructed to use soft-bristled toothbrushes, fluoridated toothpaste and interdental toothbrush or super floss. Proper oral hygiene education is provided to all the participants with the following 2-minute-long combined brushing technique.~For the evaluation of oral hygiene compliance of each orthodontic patient in each group, the gingival index according to Loë and Silness and Silness and Loe plaque index are measured at baseline (T0), 4th week (T1) and 8th week (T2). These indices are one of the standardized indicators of gingival health as it provides quantitative evaluation of the gingival status. GI and PI scores are measured by a single investigator who is calibrated. The reliability assessed by the intraclass correlation coefficient (ICC) suggested good agreement (0.85 & 0.88) for GI and PI respectively.~Data will be collected, cleaned, coded before doing the statistical analysis. The data will be checked for the range of Mean gingival index and Plaque index which should be within the range.~Sample size: The sample size was calculated to be 30 in each group, assuming a power of 80%, confidence interval of 95%, standard deviation (SD) of 0.5 and the aim of finding a 0.3 difference in the groups' means. All 60 volunteers were assessed for their eligibility before their participation.
In this day and age, smartphones are occupying big portions of our lives. Expanding development of mobile applications focusing on delivering behavioral health intervention have intrigued us to know better about their efficacy.~Hence the present study was conducted to determine the effectiveness of the Brush DJ app on improving the oral hygiene compliance of patients wearing fixed orthodontic appliances by assessing their gingival status.~Null hypothesis: There was no difference in the gingival status and oral hygiene status of patients between verbal oral hygiene instructions and oral hygiene instructions using the Brush DJ app.~Research hypothesis: There was a difference in the gingival status and oral hygiene status of patients between verbal oral hygiene instructions and oral hygiene instructions using the Brush DJ app
