Objective: To observe pattern and variation of root morphology of maxillary 1st premolar teeth in orthodontic extraction cases among local population. Study Design: Prospective Observational study. Setting: Dental College-HITEC Institute of Medical Sciences-Taxilla Cantt. Period: 1st January 2017 to 31st December 2019. Material & Methods: A total of 120 patients and 320 maxillary 1st premolars were studied clinically for gross root morphology after orthodontic tooth extraction, variation of gross root morphology was studied among extracted teeth, frequency distribution was observed on basis of gender and both quadrants in each patient, a critical analysis is also made about variation of root morphology among various populations across the world. Result: Out of 160 patients, 49 were males and 111 were females. 151 patients had bilateral similar root morphology, out of 320 clinically examined teeth 206 had two roots, and 123 teeth had fused root morphology, 83 teeth had two bifurcated (separate) roots while 114 teeth were single rooted. Conclusion: Maxillary 1st premolar is unique in terms of wide variation in root morphology which is evident among various population studies. Two roots with fused root morphology is most prevalent in Pakistani population.
Objective: The objective of this study was to determine the role of dexamethasone in mandibular third molar surgical extraction. Methodology: This cross sectional study was conducted in Oral & Maxillofacial surgery department, Liaquat University of Medical & Health sciences Hyderabad / Jamshoro. 50 cases were included in this study by using simple random sampling technique. All patients were divided into two groups. Patients in Group-A were given dexamethasone (DM)8 mg intramuscularly (IM) before surgery and 4 mg 24 hours after surgery and Augmentin tablet 625mg Q12 hrs. and Brufen 400 mg Q8 hrs. and patients in group-B were given Augmentin 625 mg BD and Brufen 400 mg TDS post operatively only. The facial swelling was checked before and after surgery.All information was collected and entered in a proforma. Results: The study sample was consisted of 62% men and 38% women. Mean age was 26.9±6.64.The mean preoperative swelling was 109.20 ± 1.190 mm in control group and 109.44 ± 1.083 in DM group. After 48 hours of surgery, post extraction swelling increased in both group with mean swelling 114.28± 1.242 mm in control group and 114.64± 1.350 in DM group, after a week of surgery more swelling was reduced in DM group as compared to control group. Conclusion: It is found that Dexamethasone group showed decrease in swelling as compared to control group.
… Introduction: Mandible is one of the most commonly fractured bones in maxillofacial trauma. Mandibular symphysis is a common site of mandibular fractures. Compare to conventional miniplates, three dimentional plates were found more effective in terms of post operative occlusion, post operative mobility of reduced fractured segments and the degree of anatomic reduction. Objectives: Compare the conventional 2.0mm mini plates versus 3D mini plates in the fixation of isolated mandibular symphysis fractures. Study Design: Interventional study.

Objectives: Compare the conventional 2.0mm mini plates versus 3D miniplates in the fixation of isolated mandibular symphysis fractures. Study Design: Interventionalstudy. Setting: Oral & Maxillofacial Surgery Department, Abbasi Shaheed Hospital Karachi.Period: Two years from 1st January 2013 to 2nd January 2015. Material & Methods: Onehundred and fifty four patients were randomly selected and allocated into two groups. Group‘I’in which patients were treated with conventional mini plates and group‘II’ where patients weretreated with 3D mini plates. Results: Mean (+SD) age of patients was 29.53 (±7.88) years.Among 154 patients in this study, majority (75.3%) of cases had age 20 - 35 years. Majority,124 (81.2)were males and 29 (18.8%) were females. In Group I, anatomic reduction at 3 monthpost-operative was observed in 30 (39%). In Group II (3D Plates) at 3 months post-operatively,ideal molar relationship was higher (89.6% Vs. 98.7%; p-value = 0.016), fracture mobility waslower (14.3% Vs. 2.6%; p-value = 0.009) and higher anatomic reduction. Conclusion: Threedimensional miniplates are more effective compared to conventional miniplates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
