The pressure pain thresholds of the subjects were measured. Patients were distributed equally by sex and randomly allocated into 3 groups: mechanical vibration, chewing gum, and control. The fixed orthodontic treatment was started in the upper jaw only. In the first and second groups, mechanical vibration was applied and sugar-free gum was chewed, respectively.

The arches were randomized into an equal number of recent and healed extraction groups. The orthodontic setup was instituted within 3-7 days and 5-6 weeks following first premolar teeth extractions in the recent and healed extraction groups, respectively. Orthodontic tooth alignment was carried out using 0.016-inch NiTi wires for 16 weeks. Study casts were made at baseline, 4, 8, 12-, and 16-week follow-up treatment. Little's Irregularity Index was used to assess orthodontic tooth alignment. Mann-Whitney U test was used to compare the alignment rates between groups, and multiple linear regression was used to predict the relationship of groups and sociodemographic factors to alignment rate. The statistical significance level was set at P < .05.Results: The mean daily incisor and canine alignment rates in the recent and healed extraction cases were 0.13 mm and 0.11 mm, respectively (P = .332), 0.12 mm in both males and females (P = .827), and 0.13 mm and 0.12 mm in the maxilla and mandible, respec- tively (P = .534). There was however a significant difference in the mean daily alignment rate between adolescents (0.15 mm) and adults (0.10 mm) (P = .019).Conclusion: The rate of incisor and canine alignment was not affected significantly by recent/healed post-extraction protocol, gen- der, and dental arch.

The degree of disease onset and severity varied from patient to patient, and most parameters indicated a greater degree of deterioration in older patients. It was found that all the muscular dystrophies studied showed altered craniofacial morphology, with malocclusion as the most consistent clinical characteristic. Particularly DM1 patients, who are the most studied, showed significant vertical aberration and post-normal occlusion. DMD patients are reported mainly with altered dental arch dimensions which influence functional capacities. Data for FSHD patients are very limited, but facial asymmetry and muscular weakness appear to be the most prominent findings. Patients with muscular dystrophies present deviations in growth and development as well as in orofacial morphology. Increased prevalence of malocclusions, of both skeletal and dental origins, characterize patients with muscular dystrophies. Different dentofacial characteristics are reported among patients with different types of muscular dystrophies.
