TOPIC: Arterial supply of the Head and Neck 🔎 INTRODUCTION The head and neck receive rich arterial blood supply from branches of the common carotid arteries and subclavian arteries. Major arteries: Common carotid artery (right from brachiocephalic trunk, left from aortic arch) Subclavian artery (both sides)
HEAD AND NECK IMPORTANT QUICK NOTES 🔍 INTRODUCTION: The head and neck region houses vital exocrine and endocrine glands that regulate saliva, hormones, tears, and more. These glands are important not only for physiology but also in clinical practice – think of swelling near the ear (parotitis), dry mouth, or thyroid nodules! 1. Salivary Glands […]
IMPORTANT NOTES ABOUT FULCRUM LINES 📍 INTRODUCTION: In removable partial dentures (RPDs), achieving stability and retention is crucial for patient comfort and function. One of the key biomechanical factors in RPD design is the fulcrum line—an imaginary axis around which the denture rotates due to functional forces. This blog post breaks down fulcrum lines, their […]
IMPORTANT REVISION NOTES 📌 INTRODUCTION: 🔹Surgical extraction of third molars (wisdom teeth) often requires carefully planned flap designs to ensure optimal access, visibility, and minimal trauma. A well-designed flap provides adequate exposure while preserving blood supply and ensuring smooth post-operative healing. 💡In this blog, we will discuss the most commonly used flap designs for third […]
TOPIC: CLASSIFICATION OF TEETH BASED ON THEIR NORMAL POSITION 📌 KEY POINTS FOR COMPLETE HUMAN DENTITION 🔷 DENTITION: Refers to all the teeth present in the mouth. 🔷 TWO SETS OF DENTITION Types of Dentition: Primary Dentition (childhood). Permanent Dentition (adulthood, also called secondary dentition). 🔷DENTAL ARCHES: Maxillary Arch: Formed by teeth in the […]
QUICK REVISION NOTES ON PARANASAL SINUSES 📌 POINTS TO PONDER 🔹Air-filled bony cavities located in the face and skull adjacent to the nose. 🔹Derive their nomenclature from the bones that they pneumatize. 🔹Occur as “paired” structures– Frontal sinuses– Maxillary sinuses– Ethmoid sinuses– Sphenoid sinuses 🔹Each sinus is connected to the nose by a small opening […]
Spillway Spaces (Interproximal Spaces/Embrasures) 📌 QUICK NOTES: 🔹 Spillway spaces are triangular-shaped spaces adjacent to the contact areas of teeth. 🔹 Spillway spaces, also known as interproximal spaces or embrasures, are the triangular spaces between adjacent teeth, located gingival to the contact point.
REPARATIVE DENTIN 📌 QUICK NOTES: Reparative dentin, also known as tertiary dentin, is formed in response to external stimuli such as trauma, caries, attrition, or dental procedures. It is produced by odontoblasts that survive the injury or by newly differentiated odontoblast-like cells.
OSTEOCLASTS: Osteoclasts are the cells which resorb the bone. Osteoclasts are derived from circulating monocytes. They are large giant cells with multiple nuclei. These cells occupy irregular resorption bays called Howship’s lacunae. ➡️ Histology of Osteoclasts Osteoclasts are large, multinucleated cells responsible for bone resorption. They derived from hematopoietic stem cells of the monocyte-macrophage lineage. […]
