The Lateral Pterygoid Muscle This is a short, thick muscle that has two heads or origin. It is a conical muscle with its apex pointing posteriorly. Origin: superior head—infratemporal surface and infratemporal crest of the greater wing of the sphenoid bone, inferior head—lateral surface of lateral pterygoid plate. Insertion: neck of mandible, articular disc, and capsule of temporomandibular joint. Innervation: mandibular nerve via lat…

Dental Amalgam and Direct Gold Restorations In restorative dentistry, understanding the properties of materials and the techniques used for their application is essential for achieving optimal outcomes.  . 1. Mechanical Properties of Amalgam Compressive and Tensile Strength Compressive Strength: Amalgam exhibits high compressive strength, which is essential for withstanding the forces of mastication. The minimum compressive strength of amalga…

MAGNESIUM The normal serum level of Magnesium is 1.8 to 2.2. mg/dl. Functions of Magnesium (a) Irritability of neuromuscular tissues is lowered by Magnesium (b) Magnesium deficiency leads to decrease in Insulin dependent uptake of glucose (c) Magnesium supplementation improves glucose tolerance Causes such as liver cirrhosis, protein calorie malnutrition and hypo para thyroidism leads to hypomagnesemia The main causes of hypermagnesemia includes…
