Persistent numbness of the lower lip and chin due to inferior alveolar nerve injury after implant placement: A clinical report.

The number of dental implants placed and restored every year is increasing across the world. However, there has been an increase in the number of reports with implant-related surgical complications in which the inferior alveolar nerve injury is the most serious one. This surgical problem can be avoided by using cone beam computed tomography (CBCT), three-dimensional (3D) implant planning software, and computer-aided design and computer-aided manufacturing (CAD-CAM) technology such as stereolithographic surgical guides.

Subtle myocardial effects of rheumatic heart disease in children are revealed earlier with two-dimensional speckle tracking echocardiography.

Objective: Rheumatic heart disease (RHD) is the most common cause of acquired heart disease in developing countries and remains a serious public health problem. In the subclinical course of carditis, the absence of typical symptoms and the normal range of classical echocardiographic measurements used to evaluate cardiac functions have required new echocardiographic methods and parameters. Previous studies regarding rheumatic heart disease in children and adults have shown that strain patterns obtained by speckle tracking echocardiography, are in fact affected although left ventricular systolic functions are preserved, yet some studies have suggested otherwise.

The effect of different types of microplastic and acute cadmium exposure on the Mytilus galloprovincialis (Lamarck, 1819).

Microplastic (MP) pollution is a pressing issue for both environmental health and the safety of human food sources. This study provides a comprehensive analysis of the effects of MPs on Mediterranean mussels (Mytilus galloprovincialis, Lamarck 1819), focusing on the food safety risks associated with MP and cadmium (Cd) exposure in these organisms intended for consumption. The retention of different polymer types of MPs in mussels was specifically evaluated, and the influence of Cd on MP retention across these polymers was investigated.

Reversal of Valproate-Induced Major Salivary Gland Changes By Moringa Oleifera Extract in Rats.

This study aimed to explore the potential protective impacts of Moringa oleifera extract on major alteration in salivary glands of rats exposed to sodium valproate (VA). Groups were defined as control, control+moringa extract, sodium valproate, and sodium valproate+moringa extract. Antioxidant and oxidant status, activities of digestive and metabolic enzymes were examined.

Effect of different implant locations and abutment types on stress and strain distribution under non-axial loading: A 3-dimensional finite element analysis.

Background/purpose: Dental implants have been a popular treatment for replacing missing teeth.
