TOPIC: AMELOGENESIS, HA CRYSTALS & ENAMEL RODS 
Amelogenesis — the process by which enamel, the hardest tissue in the human body, is formed. The amelogenesis is a tightly regulated, multi-phase process carried out by specialized cells called ameloblasts. This process occurs in two key stages: Secretory Phase – where enamel matrix proteins are laid down. […]
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: […]
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: 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 […]
Spillway Spaces (Interproximal Spaces/Embrasures): 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: 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.
DENTAL ANATOMY, EMBRYOLOGY AND ORAL HISTOLOGY 
Long Essay Q. Write an essay about tooth development. Add a note on histological and morphological differentiation of odontogenesis. Ans. Tooth Development (Odontogenesis) Tooth development, also known as odontogenesis, is a complex, highly regulated process that begins early in embryonic life and continues through early childhood. […]
DENTAL ANATOMY, EMBRYOLOGY AND ORAL HISTOLOGY LONG ANSWERS: Q: Classify oral mucus membrane. Write in detail about histology of gingiva. (15marks) Ans. 
Classification of Oral Mucous Membrane The oral mucosa lines the inside of the oral cavity and is classified into three main types based on function and structure: 1. Masticatory Mucosa: Found in areas […]
TOPIC: TOOTH NUMBERING SYSTEM KEY POINTS: Tooth numbering systems were originally developed as a shortcut to minimize the effort of hand-written record-keeping in dentistry. To identify a specific tooth, arch, quadrant, and the tooth’s name. Currently, only three most popular systems are favored worldwide. These popular systems are as follows: • Zsigmondy/Palmer (the eight-tooth quadrant) […]
