Objectives: To determine mean change in sagittal and vertical skeletal dimension in patients undergoing orthodontic treatment with all four first premolar extractions. Study Design: Quasi-experimental study design. Setting: Department of Orthodontics, Dr. Ishrat-Ul-Ebad Khan Institute of Oral Health Sciences, Dow University of Health Sciences, Karachi. Period: Six months from 18th August 2015 to 18th February 2016. Material & Methods:  50 cases treated with all first premolar extractions were included in this study. The analysis was done on pretreatment cephalogram taken at time of enrolment and post treatment lateral cephalogram taken after 12 months of orthodontic treatment and then their measurements were compared to find out changes in the sagittal and vertical dimension. Results: Pre and post mean SNA, SNB, ANB and Pog-Nperp was not significant  while mean A-Nperp was significantly changed after 12 month treatment (p=0.002). Regarding angular measurement, pre and post mean SNMP, FHMP, MMA, Go-OP, SN-OP, Y axis was not significant while mean SN-PP, UI_SN, IMPA was significantly reduced after 12 month treatment. Similarly vertical measurement, pre and post mean LAFH, PFH was not significant while mean UAFH and, TAFH was significantly reduced after 12 months of treatment. Conclusion: Sagittal and vertical skeletal dimension showed no significant change in patients undergoing orthodontic treatment with all four first premolar extractions. Some degree of extrusion was noted in all orthodontic patients who have undergone all four first premolar extractions.

Background: The aim of the study was to compare the quality of life (QoL) of cancer survivors with a control group of healthy subjects before, during, and after the orthodontic treatment. Methods: Consecutive cancer survivors (40 people) who were looking for orthodontic treatment between 2008 and 2015 were enrolled into the study. Healthy orthodontic patients matched for age (±4 years), sex, and malocclusion served as controls. The 14-item version of the Oral Health Impact Profile was used to assess the effect of orthodontic treatment on QoL before, during, and after the orthodontic treatment. Results: There were no significant differences between both groups regarding the cast model, cephalometric analysis, and photographic documentation analysis. There was a significant worsening of QoL after the onset of the orthodontic treatment with a significant improvement after the treatment. Male cancer survivor patients reported significantly lower QoL during the treatment time, which was not observed in the male control group. Conclusions: The outcome of orthodontic treatment in cancer survivors did not differ from the healthy orthodontic patients. The orthodontic treatment had an impact on the oral health quality of life both in the cancer and the control groups with a significantly higher impact in male cancer survivor patients.

Abstract Objective: To assess the frequency of maxillary ectopic canine both buccally and palatally displaced with incisor root resorption and dental agenesis. Methods: The cross-sectional study was conducted from April 8 to June 29, 2019, at the Department of Orthodontics, Dr. Ishrat Ul Ebad Khan Institute Of Oral Health Sciences, and Dow Dental College, Dow University Of Health Sciences, Karachi, and comprised orthodontic patients diagnosed with maxillary ectopic canine eruption. Root resorption and agenesis were diagnosed on panoramic films. Root resorption was further confirmed by periapical radiographs. Data was analysed using SPSS 21. Results: Of the 98 subjects, 86(87.8%) had buccally displaced canines of which 38(44.2%) were associated with root resorption, while 12(12.2%) patients had palatally displaced canines of which 10(83.3%) had root resorption (p=0.011). Overall, 30(30.6%) lateral incisors were resorbed, 7(7.1%) both central and lateral incisors, 5(5.1%) premolars, and 6(6.1%) both lateral incisors and premolars were resorbed. Agenesis was detected in 10 (10.2%) subjects (p=0.62). Conclusion: There was found to be no association of maxillary ectopic canines with incisor root resorption and dental agenesis. Key Words: Root resorption, Agenesis, Ectopic canine, Buccally displaced canine, Palatally displaced canine.
