Summary Background Retention of the maxillary anterior teeth is commonly recommended to maintain the teeth in their corrected positions. Both fixed and removable retention methods are used, but the certainty of evidence is low. Objective To evaluate post-treatment changes in irregularity of the maxillary six anterior teeth and single tooth contact point discrepancy (CPD) of three different retention methods. Trial design Three-arm parallel group single-centre randomized controlled trial. Materials and methods Ninety patients, 54 girls and 36 boys, were recruited to the study. The inclusion criteria were adolescent patients treated with fixed appliances at least in the maxilla. After gaining informed consent from the patient and their custodians, the patients were randomized to one of three groups: bonded retainer 13–23, bonded retainer 12–22, and removable vacuum-formed retainer (VFR) covering the maxillary teeth including the second molars. The randomization, prepared by an independent person, used blocks of 30. The primary outcomes were changes in single CPD and Little’s irregularity index (LII) measured on digitalized three-dimensional study casts before and after 2-year retention. The study casts were anonymized before assessment and the changes were blinded for the assessor. Data were evaluated on an intention-to-treat basis. Thus, all randomized patients were incorporated into the final analysis. Results The LII and CPDs increased slightly in all three groups without any statistically significant differences between the groups. The VFR group showed a small intercanine width increase and some more changes of canine rotations than in the other groups. Harms No harm was observed in any subjects and none of the patients needed retreatment. Limitations The trial was a single-centre study and short-term changes were evaluated. Conclusions All three retention methods showed equally effective retention capacity and all the changes found in the three groups were small and considered clinically insignificant. Thus, the null hypothesis was confirmed. All three methods can be recommended. Trial registration NCT04616755

Objectives: To evaluate the effect on post tonsillectomy pain control with IV and infiltrated dexamethasone and infiltrated bupivacaine. Methodology: This randomized controlled trial study was conducted in the department of ENT and neck surgery of Holy Family hospital, Rawalpindi, over a period of one year from May 2019 to May 2020. A total of 140 pediatric patients were selected and were divided into four equal groups randomly by lottery method. Patients in all four groups had endotracheal intubation with general anesthesia. As premedication, all the patients received intravenous midazolam (1mg). Intravenous fentanyl (1.5mg/kg) and propofol (2.5 mg/kg) followed by endotracheal intubation facilitated with atracurium (0.5 mg/kg) were used as general anesthesia in all patients. Results: There was no significant (p-value >0.05) difference in gender, age of children, postoperative heart rate, postoperative SPO2, and fentanyl consumption. The duration of surgery was significantly (p-value < 0.05) different in all four groups. According to the results, no significant (p-value >0.05) difference was found based on postoperative nausea and vomiting and the requirement of antiemetics. The requirement of analgesics was significantly (p-value <0.05) different among four groups. Minimum number (22.86%) of patients who required the analgesic were in IV dexamethasone group and highest requirement rate (60%) was found in local dexamethasone group followed by bupivacaine (48.57%) group. Conclusion: Intravenous dexamethasone was found to be more effective for early postoperative pain control and reduction in requirement of analgesics. The use of dexamethasone can be a preferred choice in patients undergoing tonsillectomy.
