Objective: This study aimed to investigate the effect of micro-osteoperforations (MOPs) on external apical root resorption (EARR) during the initial orthodontic alignment phase of maxillary anterior crowding. Methods: Thirty patients (25 females, 5 males; mean age, 22.66 ± 3.27 years) who presented with moderate crowding of the upper labial segment and underwent extraction-based fixed appliance treatment were recruited. They were randomly allocated to receive adjunctive therapy with MOPs (n = 15) or treatment with fixed appliances only (control group; n = 15). EARR was measured from long-cone periapical radiographs taken at the start and the sixth month of treatment. A correction factor for the enlargement difference was used to calculate EARR. Data were analyzed with descriptive statistics and repeated-measures analysis of variance. Results: The mean root lengths of 168 teeth were measured and showed no statistically significant difference (p > 0.05) after six months of fixed appliance treatment in the MOP (mean difference [MD] = 0.13 mm; 95% confidence interval [CI] = −0.10–0.35) and control group (MD = 0.14 mm; 95% CI = −0.10–0.37). Most of the roots in the MOP and control groups (42.86% and 52.38%, respectively) showed only mild resorption. Less than 8% of the roots in both groups (7.14% in the MOP group and 4.76% in the control group) showed moderate resorption. Conclusions Acceleration of orthodontic tooth movement with adjunctive MOPs therapy during the alignment phase does not exacerbate EARR in patients with moderate crowding of the upper labial segment in comparison with controls.

ABSTRACT This study aimed to determine the influence of dental aesthetics in finding a job as a dentist and the employer’s willingness to interact in personal and professional setting. Ten dental students’ smiling photographs were taken prior to the correction of their dental aesthetic problems. The images were digitally altered to an ideal smile. Two different questionnaires were prepared (Groups A and B) with the images with or without alteration (ideal and non-ideal smile). The images with an ideal smile and non-ideal smile were randomly allocated in each group and assessed by 84 private dental practitioners who has the authority of hiring another dentist in their practice. Four questions were asked on the likelihood of being hired, friendliness, intelligence, and good clinical skills. In general, the students with ideal smile were more likely to be hired (p < 0.05) except for those presented with buccally erupted canine and mild median diastema. Students with ideal smile scored higher in terms of friendliness and intelligence than the non-ideal smile. Most of them did not correlate a smile to an individual’s clinical skills and manual dexterity (p > 0.05). In conclusion, individuals with an ideal smile was graded more friendly and intelligent thus increases the employer’s willingness to interact personally and is more likely to be hired in contrast to a person with a non-ideal smile. Therefore, an aesthetically pleasing smile is one of the factors affecting the chances of a dentist to be hired and improve their personal interaction with people.
