European way of arrangement – First we divide the teeth into 4 equal quadrants – First 2 teeth are called Incisor Teeth (Dentes Invisivi) – Next teeth are Canine Teeth (Dentes Canini) – Premolar Teeth (Dentes Premolares) – Molar Teeth (Dentes Molares) – 8*4=32 means we have 32 premanent teeth – Milk Teeth have two incisor teeth, one canine tooth and two molar teeth Anatomy of the Gums (Gingiva): – Alveolar Mucus Membrane (Covers at the level of root of the tooth. Contains a lot of submucosal Connective tissue) – Gum Proper (attached to the periosteum) – Gingival Papillae (papillae gingivales) – Gingival Margin (margo gingivalis) – Gingival Sulcus (sulcus gingivalis) Sources used in this video: – Memorix Anatomy 2nd Edition by Hudák Radovan (Author), Kachlík David (Author), Volný Ondřej (Author) – Biorender – University notes and lectures
