Maxillary molar distalization in treatment of angle class II malocclusion growing patients: Uncontrolled clinical trial

This study was conducted to evaluate the clinical effectiveness treatment effects of a simple buccal technique for maxillary molar distalization using direct buccal skeletal anchorage.Materials and methodsAfter sample size calculation, fourteen female patients with bilateral Class II molar relationship (age 11–14 years) were selected from the clinic of the Department of Orthodontics, Faculty of Dentistry, Mansoura University, Egypt. After the application of the eligibility criteria, only eleven patients remained to final evaluation. The criteria included: erupted second maxillary molars, mild to moderate maxillary crowding not exceeding 6 mm with/without increased overjet and non-extraction treatment in the lower arch. After alignment and levelling, a miniscrew (1. 8 mm diameter – 0. 8 mm long) was placed buccally between the maxillary second premolar and the first molar in each side. The maxillary molar distalization was done using 250 grams of force produced from NiTi closed coil spring stretched to a buccal miniscrew. Records including cephalometric x-rays and study casts were taken for all patients before and after molar distalization. Statistical evaluation was performed for the data obtained from analysis of cephalometric tracing and cast photocopies.ResultsThe maxillary first molars were distalized with a rate of 0. 89 ± 0. 30 mm (95%CI 0.76–1.02) (P

In this study, patient dose optimization was implemented for a computed radiography (CR) system used in general x-ray examinations, considering physical and observer-based measurements as image quality metrics. An anthropomorphic phantom was used to simulate the patient under clinical conditions of chest and abdominal x-rays. Entrance surface doses (ESDs) were measured using a solid-state dose detector positioned at phantom entrance surface during simulated x-rays with different combinations of tube potential (kV) and tube current-time product (mAs), including the kV-mAs used clinically. Agfa's CR System with CR12-X digiti...

Early postoperative x-rays after long bone fixation in poly-trauma ICU patients rarely changes management, but adds risk and workload, especially for ventilated patients. Intra-operative fluoroscopy might be sufficient until the patient's general condition has improved. Radiographic imaging remains a cornerstone of orthopaedic practice, both in the preoperative assessment and postoperative follow-up of orthopaedic trauma patients [1]. Traditionally, control x-rays are routinely requested during the immediate postoperative period in order to evaluate the adequacy of reduction and fixation.

Conclusions: Surgical excision of forearm osteochondromas with ulnar tether release in the preadolescent patients improves carpal slip, may help to prevent subsequent surgical reconstruction and provides satisfactory clinical results at an average 7-year follow-up. Level of Evidence: Level III—therapeutic study.

Conclusions: We report a significant association between pediatric athletes who play basketball and soccer and the development of trochlear JOCD, suggesting that repetitive loading of the patellofemoral joint may play a role in the development of JOCD lesions. Patients with trochlear JOCD lesions were likely to undergo surgery, and repair and fixation of the lesions produced good outcomes at short-term follow-up. Level of Evidence: Level III—case-control study.

Authors: Szczęsny G, Ratajczak K, Fijewski G, Małdyk P Abstract An 86-year-old female was operated on due to a comminuted fracture of the right proximal humerus whose configu-ration necessitated over-screwing of the humeral head to improve stability, with the screws directed divergently: anteriorly and poste-riorly, to minimize their conflict with the acetabulum. 3.5 years later she sustained a corresponding fracture of the left shoulder which was stabilized without over-screwing. On both occasions, the fractures were stabilized with titanium interlocking plates (ChM, Poland) and the limbs were immobilized in a s...

Unstable distal metaphyseal and dia-metaphyseal fractures of the radius may have treated with a variety of operative techniques, Kirschner wires (K-wires), dorsally inserted titanium elastic stable intramedullary nailing (DESIN), and short titanium elastic stable intramedullary nailing (SESIN) in children. The aim of this study was to evaluate the differences in clinical and radiographic outcomes between these methods. Between January 2009 and December 2017 196 children were treated for forearm fractures in the distal third of the distal radius. Gender of the patients, different types of surgical techniques, number of po...

Qure’s scientists began investigating the algorithm’s mysteriously high performance on chest radiographs from a new hospital. To recap, the algorithm had an area under the receiver operating characteristic curve (AUC) of 1 – that’s 100 % on multiple-choice question test. “Someone leaked the paper to AI,” laughed Manoj. “I...
