Brief summary

Objective: To determine the effect of WhatsApp and Email reminders on oral hygiene compliance of orthodontic patients. Methods: A Randomized, parallel group, double blinded study was conducted on 54 patients undergoing orthodontic treatment at MAHSA University. They were randomized to 3 groups, namely WhatsApp (W) group, Email (E) group and Control (C) group with 18 subjects in each group. Group (W) and Group (E) received oral health messages once a week through WhatsApp and E-mail reminders respectively, while Group (C) did not receive any reminders. Plaque was measured at baseline (T0), after 4 weeks (T1), and after 8 weeks (T2). For each subject, two intraoral photographs were taken after application of plaque disclosing agent; and the area covered by plaque was measured on 12, 13, 43, 22, 23 and 33 teeth by planimetry.

Detailed description

Fifty-four patients undergoing orthodontic treatment were recruited from the dental clinic of MAHSA University between Jan 2018 to April 2018. Voluntary written informed consent was obtained from all the subjects before the start of the study. They were randomly assigned into 3 groups namely WhatsApp (W) group, Email (E) group and Control (C) group with 18 subjects in each group. Oral hygiene messages through WhatsApp and Email were sent once a week for 8 weeks.

Interventions

The WhatsApp group received oral health messages once a week for four weeks (totaling 4 messages) as a reminder to practice good oral hygiene The reminder included an image reminding them to maintain their oral hygiene.

BEHAVIORALEmail reminder

The Email group received oral health messages once a week for four weeks (totaling 4 messages) as a reminder to practice good oral hygiene The reminder included an image reminding them to maintain their oral hygiene.

BEHAVIORALControl

No messages sent.

MeasureTime frameDescription
Change in plaque from baseline to 4 weeksbaseline (T0) to end of 4 weeks (T1)Plaque disclosing solution was applied to the pre-selected teeth (12,13,43, 22, 23, 33) followed by measurement of plaque using planimetry. All photographs were taken using a Canon Electro-Optical System (EOS) 550D (camera specifications). Plaque was analyzed using Image J software. Change in plaque score is assessed from baseline to 4 weeks in all the three groups. In the photo, region of interest targeted by the study was manually outlined using Polygon selection tool, the total pixel present in this region is calculated by tracing tool. The pixel of the plaque area is determined by adjusting the color threshold to desirable range of value. The plaque sore was calculated in the form of percent covering tooth structure and the value of plaque on each tooth was determined and mean plaque was calculated.
