The influence of text messages on the cooperation of Class II patients regarding the use of intermaxillary elastics.

Abstract

OBJECTIVES:

To evaluate the influence of text messages on cooperation of Class II patients with the use of intermaxillary elastics.

MATERIALS AND METHODS:

The sample consisted of 42 orthodontic patients (20 males and 22 females) aged between 14 and 34 years. They were randomly divided into one of the following two groups: a control group with 21 patients who did not receive messages and an experimental group with 21 patients who received motivational and reminder text messages. Messages were sent twice a week for a period of 3 months. The patients were instructed to wear the elastics all day, removing them only during meals and replacing them daily. All patients were instructed regarding the importance of cooperation. Measurements were performed with a digital caliper on plaster models at the beginning of elastics wear (T1) and 3 months later (T2). For intragroup and intergroup comparisons between T1 and T2, paired and unpaired t-tests, respectively, were used with a significance level of 5%.

RESULTS:

Statistically significant differences were observed in the intra- and intergroup comparisons between T1 and T2. Both groups showed a decrease in the sagittal distance between upper and lower arches from T1 to T2, demonstrating the effective use of elastics. However, the experimental group showed a Class II correction that was 3.7 times greater than the control group ( P = .001).

CONCLUSIONS:

Text messages had a positive influence on the cooperation of patients regarding the use of intermaxillary elastics in the orthodontic treatment of Class II malocclusion.
