Abstract Background: Orthodontic appliances complicate daily oral hygiene maintenance and enhance the formation of microbial biofilm on tooth surfaces and orthodontic appliances. Any tool that enhances the oral hygiene of patients during orthodontic treatment would be of imperative beneficial. This trial was conducted to assess the effect of message reminders on oral hygiene of patients during removable orthodontic treatment. Methods: In this 2-arm parallel randomized controlled trial, participants were randomly allocated to two groups; one receiving messages reminder and one as the control group. The patients in the messaging group received one or two message reminders and educational videos weekly during the course of treatment. The patients with removable maxillary appliance who were in the age range of 8 to 12 years old and had daily access to Internet to receive message reminders were recruited in this study. A single blinded examiner measured the plaque index (PI), gingival index (GI) and dental caries index of patients in both groups at baseline (T0) and one (T1), three (T2) and six (T3) months after the first day of treatment to assess their oral hygiene status during the course of treatment in both groups. Results: A total of 50 patients were enrolled and randomized to two even groups (n=25) but only 46 patients completed the study; 22 in control group, and 24 in message reminder group. The PI and GI scores were increased neither in control group nor in message reminder group during T0 and T1, significantly. The PI and GI scores in message reminder group were significantly lower than those in the control group at T2 (PI: P=0.003, GI: P=0.001) and T3 (PI: P=0.044, GI: P=0.012). However, slight significant increasing in the PI and GI score were found during T2 and T3 during in message reminder group. Caries index showed no significant difference between two group during study.Conclusion: It seems that message reminders can efficiently promote oral hygiene of patients undergoing removable orthodontic treatment. Although, this promotion wasn’t progressive.

ABSTRACT Background No randomized controlled trial has tried to compare transverse dental arch changes between the lingual and labial orthodontic fixed appliances in the early stage of treatment. Objective To compare upper dental arch changes between lingual and labial fixed orthodontic appliances after leveling and alignment. Design, setting Parallel-groups randomized controlled trial on patients with class I moderate crowding teeth treated at the University of Al-Baath Dental School in Hamah, Syria. Participants About 102 patients with crowded teeth and class I malocclusion were evaluated and 58 patients fulfilled the inclusion criteria. Randomization was performed using computer generated tables; allocation was concealed using sequentially numbered opaque and sealed envelopes. About 52 participants were analyzed (mean age 21.5 ± 3.2 years). They were randomly distributed into two groups with 26 patients in each (1:1 allocation ratio). Intervention Lingual vs labial fixed orthodontic appliances were used. Main outcome measure Intercanine width, interpremolar width, intermolar width, and arch length were measured on study models before brackets’ placement (T1), at the end of leveling and alignment stage (T2). Results Statistically significant increase was detected in the intercanine width in the lingual group (1.99 mm, p < 0.001) and in the labial group (1.22 mm, p < 0.001). The interpremolar width had a significant decrease in the lingual group (–0.70 mm, p < 0.001), whereas there was a significant increase in this width in the labial group (1.73 mm, p < 0.001). A significant decrease in intermolar width was detected in the lingual group (–0.79 mm, p < 0.001) whereas a significant increase was observed in the labial group (0.81 mm, p < 0.001). The differences between the two groups were significant for all comparisons (p < 0.001). Conclusion The labial appliance produced a significant increase in all horizontal transverse arch dimensions, whereas in the lingual appliance group the intercanine width increased significantly in conjunction with a significant narrowing of posterior segments.

Purpose This study reports on the treatment fidelity procedures implemented during a 5-year randomized controlled trial comparing intensive and distributed comprehensive aphasia therapy. Specifically, the results of 1 treatment, verb network strengthening treatment (VNeST), are examined. Method Eight participants were recruited for each of 7 consecutive cohorts for a total of 56 participants. Participants completed 60 hr of aphasia therapy, including 15 hr of VNeST. Two experienced speech-language pathologists delivered the treatment. To promote treatment fidelity, the study team developed a detailed manual of procedures and fidelity checklists, completed role plays to standardize treatment administration, and video-recorded all treatment sessions for review. To assess protocol adherence during treatment delivery, trained research assistants not involved in the treatment reviewed video recordings of a subset of randomly selected VNeST treatment sessions and completed the fidelity checklists. This process was completed for 32 participants representing 2 early cohorts and 2 later cohorts, which allowed for measurement of protocol adherence over time. Percent accuracy of protocol adherence was calculated across clinicians, cohorts, and study condition (intensive vs. distributed therapy). Results The fidelity procedures were sufficient to promote and verify a high level of adherence to the treatment protocol across clinicians, cohorts, and study condition. Conclusion Treatment fidelity strategies and monitoring are feasible when incorporated into the study design. Treatment fidelity monitoring should be completed at regular intervals during the course of a study to ensure that high levels of protocol adherence are maintained over time and across conditions.
