To evaluate the levels of acceptance and discomfort between two types of functional appliances. Study design: Randomised controlled trial.
A sample of patients who met the inclusion criteria were distributed randomly and equally into two groups: the Trainer for Kids™ made up of 26 patients with an average age of 10.3 years (Group A), and the modified Activator with 28 patients, with an average age of 10.6 years (Group B), as control. A special questionnaire including eight questions about tension, pressure, sensitive teeth, pain, impaired speech, impaired swallowing, oral constraint and lack of confidence in public caused by the appliance was administered at T1 (7 days), T2 (14 days), T3 (3 months), and T4 (6 months).
The sensation of pressure, teeth sensitivity, pain and impaired speech declined significantly in Group A. All complaints decreased significantly in Group B, but the changes in 'lack of confidence in public' were not significant. Moreover the sensation of pressure, teeth sensitivity, oral constraint and impaired speech were significantly higher in Group A than in Group B.
The modified Activator caused less discomfort than the Trainer for Kids™ and was more acceptable.

    ABSTRACT: Aim: To determine the degree of pain and discomfort during the orthodontic treatment of skeletal Class III malocclusion using the Removable Mandibular Retractor (RMR). Materials and methods: The sample consisted of 33 skeletal Class III patients (17 males and 16 females; average age: 7.5 ± 1.33 years) who had been assigned to the RMR treatment group in a randomised controlled trial comparing this treatment versus a control group of no treatment at the Orthodontic Department, University of Al-Baath Dental School in Syria. Pain and discomfort were assessed using standardised questionnaires at the following assessment times: 7 days (T1), 14 days (T2), 6 weeks (T3), 3 months (T4) and 6 months (T5) after appliance insertion. Results: Levels of pain and discomfort decreased gradually by time in general. No significant changes in the levels of pain, tooth sensitivity and soft tissues tension were detected, whereas a significant decrease in the levels of pressure, impaired speech, impaired swallowing and lack of confidence in public was observed two weeks following appliance insertion. Mandibular constraint feeling required three months to decrease significantly. No difference was found between males and females with regard to acceptance. Conclusion: The RMR is well accepted by Class III patients in the early mixed dentition.
