TOPIC: HISTOPHYSIOLOGY & MOLECULAR INSIGHTS 🔍 What is Histophysiology? 🔸It is the study of tissue structure (histology) along with function (physiology). 🔸In tooth development, it refers to how specific cells differentiate, secrete, and organise to form dental tissues. 🔍 Histophysiological Changes in Tooth Development 1. Odontoblast Differentiation 🔹Origin: Dental papilla cells adjacent to Inner Enamel […]
TOPIC: TOOTH DEVELOPMENT & OSTEOGENESIS REVISION NOTES 👉 Tooth development is a highly organized and complex biological process that starts early in embryonic life. It involves a series of reciprocal interactions between the oral epithelium and the underlying ectomesenchyme, leading to the formation of highly specialized structures — our teeth. 👉 We’ll be focusing on: […]
TOPIC: TRIANGLES OF THE NECK – Concise Notes 📌 INTRODUCTION 🔺The neck is divided into triangles for anatomical understanding and surgical reference. 🔺Two main triangles: Anterior triangle Posterior triangle 1. POSTERIOR TRIANGLE ➡️ Boundaries Anterior: Posterior border of sternocleidomastoid (SCM) Posterior: Anterior border of trapezius
TRIGEMINAL & FACIAL NERVE – Concise Lecture Notes TOPIC: TRIGEMINAL & FACIAL NERVE I. TRIGEMINAL NERVE (CN V) 👉 Type: Mixed nerve (Motor + Sensory) 👉 Largest cranial nerve; Principal sensory nerve of face 1. ORIGIN Four nuclei in the pons: 1 Motor nucleus (pons) 3 Sensory nuclei (mesencephalic, main sensory, spinal) 2. DIVISIONS 👉 […]
QUICK REVISION NOTES 📌 Introduction to Osteology 🔸Osteology is the study of bones, which make up the skeletal system. 🔸The adult human skeleton has 206 bones. 🔸These bones are categorized into two main groups: Axial Skeleton: Skull, vertebral column, ribs, and sternum. Appendicular Skeleton: Limbs and girdles.
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 […]
