Evaluation of user experience and satisfaction with workplace-based assessments (WPBAs) in dental postgraduate programmes.

Objectives: To explore the experience of and satisfaction with workplace-based assessment tools among dental postgraduate trainees.

Methods: The cross-sectional study was conducted from March to October 2022 at the Aga Khan University Hospital, Karachi, and comprised all Operative Dentistry, Prosthodontics and Orthodontics postgraduate trainees. A questionnaire with both open-ended and closed-ended questions was used to record the experiences and satisfaction level of the dental residents who had earlier been subjected to workplace-based assessment.

Influence of dental midline deviation with respect to facial flow line on smile esthetics-A cross-sectional study.

Background/objective: A contemporary concept states that dental midline deviation towards the direction of facial flow line (FFL) can mask the compromised smile esthetics. This study aimed to identify a range of midline deviations that can be perceived towards or away from the FFL influencing smile esthetics.

Materials And Methods: A cross-sectional study was conducted using a frontal smile photograph of an adult female.

Does Local Aqueous Tobramycin Injection Reduce Open Fracture-Related Infection Rates?

Objectives: To examine the effect of local aqueous tobramycin injection adjunct to perioperative intravenous (IV) antibiotic prophylaxis in reducing fracture-related infections (FRIs) following reduction and internal fixation of open fractures.

Design: Retrospective cohort study.

Setting: Single academic Level I trauma center.

A Cadaveric Study: Does Ankle Positioning Affect the Quality of Anatomic Syndesmosis Reduction?

Objective: The objective of this study was to compare the quality of syndesmotic reduction with the ankle in maximal dorsiflexion versus neutral plantarflexion (normal resting position).

Methods: Baseline computed tomography (CT) imaging of 10 cadaveric ankle specimens from 5 donors was obtained with the ankles placed in normal resting position. Two fellowship-trained orthopaedic surgeons disrupted the syndesmosis of each ankle specimen.

UNETR++: Delving Into Efficient and Accurate 3D Medical Image Segmentation.

Owing to the success of transformer models, recent works study their applicability in 3D medical segmentation tasks. Within the transformer models, the self-attention mechanism is one of the main building blocks that strives to capture long-range dependencies, compared to the local convolutional-based design. However, the self-attention operation has quadratic complexity which proves to be a computational bottleneck, especially in volumetric medical imaging, where the inputs are 3D with numerous slices.

Nonoperative Treatment of Humeral Shaft Fractures With Immediate Functional Bracing Versus Coaptation Splinting and Delayed Functional Bracing: A Retrospective Study.

Objectives: To compare radiographic and clinical outcomes in nonoperative management of humeral shaft fractures treated initially with coaptation splinting (CS) followed by delayed functional bracing (FB) versus treatment with immediate FB.

Design: Retrospective cohort study.

Setting: Academic Level 1 Trauma Center.

Does Scheduled Low-Dose Short-Term NSAID (Ketorolac) Modulate Cytokine Levels After Orthopaedic Polytrauma? A Secondary Analysis of a Randomized Clinical Trial.

Objectives: To determine whether scheduled low-dose, short-term ketorolac modulates cytokine concentrations in orthopaedic polytrauma patients.

Design: Secondary analysis of a double-blinded, randomized controlled trial.

Setting: Single Level I trauma center from August 2018 to October 2022.

Talar Neck Fractures With Associated Ipsilateral Foot and Ankle Fractures Have a Higher Risk of Avascular Necrosis.

Objectives: To determine if talar neck fractures with concomitant ipsilateral foot and/or ankle fractures (TNIFAFs) are associated with higher rates of avascular necrosis (AVN) compared with isolated talar neck fractures (ITNs).

Design: Retrospective cohort.

Setting: Single level I trauma center.

Facial flow line and its effect on dental midline deviation on a female subject in an Asian population - A cross-sectional study.

Introduction: This study aims to understand the relationship between midline deviations and the inherent asymmetry that can be observed in a human face.

Materials And Methods: A cross-sectional study was conducted using a frontal smile photograph of a female which was altered on Adobe Photoshop software version 23.0 into eight different photographs by deviating the dental midlines by 2 mm, 4 mm, and 6 mm towards and away from the facial flow line (FFL).

Advancements in TiO-based photocatalysis for environmental remediation: Strategies for enhancing visible-light-driven activity.

Researchers have focused on efficient techniques for degrading hazardous organic pollutants due to their negative impacts on ecological systems, necessitating immediate remediation. Specifically, TiO-based photocatalysts, a wide-bandgap semiconductor material, have been extensively studied for their application in environmental remediation. However, the extensive band gap energy and speedy reattachment of electron (e) and hole (h) pairs in bare TiO are considered major disadvantages for photocatalysis.

ChatGPT: Transcending Language Limitations in Scientific Research Using Artificial Intelligence.

Health and scientific researchers in non-English speaking countries such as Pakistan, are not proficient in English, which limits their ability to communicate their ideas and findings to the international scientific community. ChatGPT is a large language model that can help non-native English speakers to write high-quality scientific papers much faster by assisting them in conveying their ideas in a clear and understandable manner, as well as avoiding common language errors. In fact, ChatGPT has already been used in publication of research papers, literature reviews, and editorials.

Comparison of mesiodistal root angulation of teeth by conventional panoramic and cone beam computed tomography images - A cross-sectional study.

Introduction: Accurate bracket positioning is required for proper root parallelism and for stable orthodontic treatment outcomes. This study aimed to determine the difference in mesiodistal root angulation of teeth measured on three radiographic images.

Material And Methods: A cross-sectional study was conducted using orthopantomogram (OPG), panoramic images of cone beam computed tomography (Pan-CBCT) and cone beam computed tomography (CBCT).

Soft tissue lasers: An innovative tool enhancing treatment outcomes in orthodontics - A narrative review.

Lasers have been utilised in the field of dentistry for over 40 years, but their use has been limited in the field of orthodontics. The advent of lasers with accompanying computer interfaces has made them significantly user-friendly, adding to their appeal in the orthodontic profession. Knowledge regarding the laser device's capabilities and limitations is essential to optimise patient care and to make a satisfactory investment return.

Graft Options for Hip Labral Reconstruction.

➢: Arthroscopic hip labral reconstruction is a complex procedure which is growing in use as indications, techniques, and surgical expertise advance.

➢: Graft selection is an important component of labral reconstruction based on relative advantages and disadvantages of available types of autografts and allografts.

➢: The ideal graft should mimic the native acetabular labrum form and function while also being affordable, readily available, and associated with low morbidity.
