RESUMEN
OBJECTIVES: Tele-orthodontics is an important medium to use for diagnosis and treatment planning and to refer patients for specific treatment when deemed necessary. The effectiveness of the Tele-orthodontics Education Model serves to improve resident's knowledge, confidence, and skills in delivering tele-orthodontic patient care. The purpose of this educational single-arm pre-test-post-test interventional study was to assess and educate orthodontic residents (6 year-one, and 6 year-two) to appropriately use tele-orthodontics. METHODS: The Tele-orthodontics Education Model utilizes three learning modules, a questionnaire before and after the training to assess participant knowledge, confidence and skills levels, three online multiple-choice questionnaires, three explanatory videos and an in-person simulation session. The Blackboard Learning Management System (virtual learning platform) facilitates access to the various modules of the program. Within each learning module, a participant's knowledge level was determined by utilizing five multiple-choice questions before and after each module. The various modules were introduced to the participants and then evaluated by reviewing the participant's responses to the multiple-choice questions. RESULTS: Twelve orthodontic residents completed the model in one session. Everyone fully completed the questionnaire. Post-test results showed higher mean scores for all questions addresses knowledge, the mean confidence, and skills score for post-test showed no change when compared to pre-test. CONCLUSIONS: This education model was effective in improving basic knowledge in tele-orthodontics among first, and second-year orthodontic residents. We hypothesize that the residents are more informed and prepared for future tele-orthodontic practices.
RESUMEN
OBJECTIVES/HYPOTHESIS: The aim of this study was to compare the volume of nasopharyngeal airways of patients with unilateral cleft lip and palate (UCLP) with a control (noncleft) group of subjects. STUDY DESIGN: Retrospective case-control study. METHODS: The sample consisted of 45 subjects, 30 with UCLP who underwent cone beam computed tomography (CBCT) exams as part of their workups for alveolar bone graft and 15 noncleft subjects seeking orthodontic care who obtained CBCT for diagnostic purposes. The three-dimensional volumes of nasal (NV) and oropharyngeal (PV) airways of these subjects were assessed separately using Mimics software by one well-calibrated evaluator. The images were rendered, and the volumes were measured in cm(3). RESULTS: The mean PV of the UCLP subjects was 6.7 cm(3) and the mean NV was 10.3 cm(3). The control group presented with a mean PV of 8.1 cm(3) and a mean NV of 11.6 cm(3). Student t test showed no statistically significant difference for PV (P = 0.10) or NV (P = 0.23) when comparing cleft and noncleft subjects. CONCLUSION: Evaluation of the nasopharyngeal airways revealed that the NV and PV airways showed no difference between the cleft and noncleft subjects. It is interesting to postulate that the reported nasal abnormalities of the cleft patients do not produce a significant measurable effect on the overall volume, at least as shown in our study sample. In addition, the nasopharyngeal airways of patients are not larger than those of age-matched controls, at least at the ages that were sampled, after cleft palate repair.
