This in vitro study aims to evaluate various surface treatments on the shear bond strength and failure mode of CAD/CAM PMMA teeth to the heat-polymerized acrylic denture base. The study sample consisted of 100 teeth that were divided equally into five groups: Group 1: denture artificial teeth (control), Group 2: PMMA teeth without surface treatment, Group 3: PMMA teeth with MMA etching, Group 4: PMMA teeth with sandblasting (aluminum oxide particles), and Group 5: PMMA teeth with perpendicular grooves. The shear bond strength test was performed using a universal testing machine and the failure mode was recorded.

Background: Soft tissue specifications and facial values vary depending on the underlying skeletal structures. To achieve the ideal treatment result and patient satisfaction, one must know the attractive soft tissue specifications compatible with each type of malocclusion. This study aims to analyze the facial measurements that contribute to perceived facial attractiveness in patients with vertical growth patterns and skeletal class I malocclusion, focusing on gender-specific differences.

Background: Guillain-Barré syndrome (GBS) is an autoimmune disease that affects the peripheral nervous system leading to motor, sensory, and sometimes autonomic manifestations. Therapeutic plasma exchange (TPE), which involves the selective removal of pathological molecules, such as auto-antibodies, from plasma, has proven to be safe and effective in adults with GBS. However, its application in pediatric patients lacks sufficient evidence.

Head and neck cancer (HNC) represents a challenging oncological entity with significant morbidity and mortality rates. Despite advances in conventional therapies, including surgery, chemotherapy, and radiation therapy, the overall survival rates for advanced HNC remain suboptimal. In recent years, the emerging field of oncolytic virotherapy has gained attention as a promising therapeutic approach for various malignancies, including HNC.

Despite the large number of studies that have been done in this area, there is still a gap in the literature when it comes to comparing the orthodontic tooth movement (OTM) efficacy of Invisalign and fixed orthodontic appliances. The primary objectives of this study were to evaluate and compare the efficacy of Invisalign and fixed orthodontic appliances in terms of the amount and rate of OTM. Specifically, the study aimed to determine if there was a statistically significant difference between these two treatment modalities in achieving OTM and to assess whether treatment duration differs significantly between Invisalign and traditional fixed appliances.

Dentofacial deformities can significantly impact an individual's quality of life, affecting facial aesthetics, self-esteem, and overall well-being. The combined orthognathic surgery-orthodontic treatment is the preferred approach for correcting moderate-to-severe deformities. However, patient satisfaction following orthognathic surgery remains a crucial outcome measure, influenced by various factors, including the type of malocclusion, surgical procedure, and demographic characteristics.

Background And Objectives: Fixed orthodontic appliances interfere with daily oral care procedures, causing more plaque accumulation and thus increasing the risk of periodontal diseases. Probiotics have been suggested to maintain oral health using beneficial bacteria. However, the evidence to determine the clinical benefits of probiotics as a supplement to oral health in orthodontic patients is still insufficient.

With the innovation of three-dimensional imaging and printing techniques, computer-aided surgical planning, also known as virtual surgical planning (VSP), has revolutionized orthognathic surgery. Designing and manufacturing patient-specific surgical guides using three-dimensional printing techniques to improve surgical outcomes is now possible. This article presents an overview of VSP in orthognathic surgery and discusses the advantages and accuracy of this technique compared to traditional surgical planning (TSP).

Background: Gingival phenotype (GP), comprising gingival thickness (GT) and keratinized tissue width (KTW), plays a crucial role in preserving the integrity of gingival and periodontal tissues, thereby enhancing their resistance to trauma and mechanical irritation. This systematic review and meta-analysis aimed to evaluate the current evidence about the changes in GT and KTW following the injection of injectable platelet-rich fibrin (i-PRF) in patients with thin GP.
Methods: A thorough search was conducted up to April 2024 across the following nine databases: The Cochrane Central Register of Controlled Trials (CENTRAL), PubMed, Scopus, Web of Science, Google Scholar, Trip, CINAHL via EBSCO, EMBASE via OVID, and ProQuest.

Introduction: Many efforts have been made to shorten fixed appliance orthodontic treatment time by accelerating the rate of tooth movement. Low-intensity electrical stimulation (LIES) is one of the proposed physical methods that has not yet been well studied in the medical literature. This study aimed to evaluate the effectiveness of LIES in accelerating orthodontic tooth movement in cases of en-mass retraction of the upper anterior teeth.

Background and objectives Pediatric thoracic surgery has unique considerations due to the immaturity of the respiratory system anatomically and physiologically, which presents technical and pharmacological considerations, including the very common technique of one-lung ventilation (OLV), which causes serious complications in children. Therefore, we investigated the effects of dexmedetomidine on oxygenation and pulmonary shunt fraction (Qs/Qt) in high-risk pediatric patients undergoing OLV for thoracic surgery. This randomized controlled trial aimed to investigate dexmedetomidine's effect on the partial pressure of arterial oxygen (PaO) and pulmonary shunt fraction (Qs/Qt).
