Infections caused by N. meningiditis 1.  Bacteremia without sepsis.  Organism spreads to blood but no major reaction. 2.  Meningococcemia without meningitis.  Fever, headache, petechia, hypotension, disseminated       intravascular coagulation.  The Waterhouse-Friderichsen Syndrome is a rapid, progressive meningococcemia with shock, organ failure, adrenal necrosis, and death. 3.  Meningitis with meningo…

The Lateral Wall of the Orbit This wall is thick, particularly its posterior part, which separates the orbit from the middle cranial fossa. The lateral wall is formed by the frontal process of the zygomatic bone and the greater wing of the sphenoid bone. Anteriorly, the lateral wall lies between the orbit and the temporal fossa. The lateral wall is partially separated from the roof by the superior orbital fissure.…

Key Cephalometric Landmarks Sella (S): The midpoint of the sella turcica, a bony structure located at the base of the skull. It serves as a central reference point in cephalometric analysis. Nasion (N): The junction of the frontal and nasal bones, located at the bridge of the nose. It is often used as a reference point for the anterior cranial base. A Point (A): The deepest point on the maxillary arch, l…

Cementum & Cementogenesis Cementum formation is called cementogenesis and occurs late in the development of teeth. Cementoblasts are the cells responsible for cementogenesis. Two types of cementum form: cellular and acellular. Acellular cementum forms first. The cementoblasts differentiate from follicular cells, which can only reach the surface of the tooth's root once Hertwig's Epithelial Root Sheath (HERS) has begun to deteriorate. The cementobla…
