The purpose of this study was to investigate the fracture resistance, biocompatibility, hardness, and transverse strength of non-precious metal alloy (chromium-cobalt; Cr-Co), titanium (Ti), zirconia (Zr), polymethylmethacrylate (PMMA), and polyetheretherketone (PEEK) when employed as substructure materials according to the implant supported full arch fixed prosthesis treatment concept. ⋯ Within the limitations of this study, the most favorable materials in terms of biocompatibility were found as PEEK and Zr. When biomechanical properties are evaluated, the most durable materials can be specified as Cr-Co and Zr. Also, further studies are needed to improve material stability.

The aim of this study was to investigate prevalence and pattern of self-medication with alternative medicine (ALM) among oral submucous fibrosis (OSF) patients with emphasis on treatment-switch analysis. ⋯ ALM usage is common in OSMF patients with significant percentage of patient switched from modern medicine to ALM. Therapeutic efficacy of ALM in OSF needs exploration in future.

The aim of this study was to explore adolescents' (11-20 years) usage of, beliefs in, attitudes toward, and barriers to contact lens use in Riyadh, Saudi Arabia. ⋯ The percentage of contact lens users was relatively low. A substantial number of older adolescents and females were found to wear contact lenses, although without proper professional consultation. Knowledge of and attitudes toward contact lenses among adolescents were in acceptable levels. These results gave indications that contact lens usage in adolescents can be achievable and valuable for refractive error correction, especially for those who are non-compliant with glasses.

Observational Study
Pedicle Screw Fixation with Percutaneous Vertebroplasty for Traumatic Thoracolumbar Vertebral Compression Fracture.
This study aims to evaluate the clinical efficacy of percutaneous pedicle screw fixation (PPSF) combined with percutaneous vertebroplasty (PVP) for the treatment of the thoracolumbar vertebral compression fracture (VCF) without neurologic deficits. ⋯ PPSF combined with PVP procedure is a good choice for the treatment of traumatic thoracolumbar VCF; however, due to the lack of long-term follow-up data, concern still exists regarding the effects of pedicle screw procedure after PVP.

To investigate the prevalence and presentation of polypoidal choroidal vasculopathy (PCV) in Nigerians. ⋯ PCV is a cause of vision loss among Nigerians. Majority of the eyes were blind and 50% of blind eyes had vitreous hemorrhage. Since Indocyanine Green Angiography is the most appropriate imaging technology and is mostly unavailable in Nigeria, efforts should be made to address this need and improve the diagnostic accuracy.
