Objectives: The aim of this study was to evaluate a possible relationship between preferred chewing side (PCS) and the anterior guidance angle.
Subjects And Methods: Forty dental nurses and technicians, aged 24-46 years, were each given a piece of chewing gum, which they chewed for about 3 min. At 7 regular intervals (every 15 s), they were interrupted by the principal investigator (P.L.) in order to observe on which side of their mouths they had the bolus of chewing gum. Moulds of their jaws were made and the position of the maxillary arch relative to temporomandibular joints was recorded with a facebow and transferred to a semi-adjustable articulator. After mounting the stone casts of each subject, a measure of the anterior guidance angle was taken with an adjustable incisal table.
Results: Of the 40 subjects, 14 (35%) presented a PCS. Among the 14 subjects who preferred a chewing side, there was a correlation between the PCS and a low angulation of teeth constituting the anterior guidance on that side, but this correlation was statistically nonsignificant.
Conclusion: In this study, we found that unilateral chewing creates uneven wear on the anterior teeth and changed the anterior guidance angulation.

Purpose: to characterize mastication and electrical activation of the masseter and anterior temporalis muscles in children and adolescents with osteogenesis imperfecta (OI), and relate results to guided occlusion and occlusal interference.
Methods: This observational, analytical cross-sectional study included 22 subjects divided into mild OI (MOI) (type 1) (n=15) and moderate-to-severe OI (MSOI) (types 3, 4, and 5) (n=7) groups. The Orofacial Myofunctional Evaluation with Scores (OMES) form was used to evaluate the clinical aspects of mastication.

Anterior prostate cancers (APCs) are a group of impalpable neoplasms located in regions anterior to the urethra, which comprise the transition zone, apical peripheral zone and anterior fibromuscular stroma. These regions are typically undersampled using conventional biopsy schemes, leading to a low detection rate for APC and a high rate of false negatives. Radical prostatectomy series suggest prevalence rates of at least 10-30%, but transperineal systematic biopsy is ideal for diagnosis, particularly where multiparametric MRI is unavailable.

The efficacy of epidural blood patch (EBP) is highly variable, and often, clinicians are unable to identify the underlying reasons for treatment failure. A 36-year-old parturient underwent a "blind" epidural blood patch (EBP) without image guidance but failed to obtain relief from a postural headache related to the labor epidural. During the second EBP, an intact plica mediana dorsalis (PMD) was visualized in the anterior-posterior fluoroscopic view after injection of contrast, and autologous blood was injected on both sides of the PMD, leading to the complete resolution of headache symptoms.

Background: Transcatheter closure of large and complex atrial septal defect can pose challenges and complications during device placement. To improve stability, several assistive techniques have been developed.
Methods: This retrospective study evaluated the efficacy of the device-assisted device closure technique for large secundum atrial septal defects.

: Asymptomatic patellar tendon abnormality (APTA) is considered a precursor to patellar tendinopathy (PT), but its pathogenesis remains unclear, especially regarding changes in muscle coordination. Therefore, it is essential to explore the muscle synergy patterns in individuals with APTA. This study recorded sEMG data during stop-jump tasks in 8 APTA and 8 healthy amateur male basketball players in a simulated basketball game.
