![]() The crown of a tooth is the portion of the tooth that’s visible. The pulp cavity, sometimes called the pulp chamber, is the space inside the crown that contains the pulp. It’s made of tiny blood vessels and nerve tissue. Pulp is the innermost portion of the tooth. Gums, also called gingiva, are the fleshy, pink connective tissue that’s attached to the neck of the tooth and the cementum. It forms the line where the cementum (that covers the root) meets the enamel. The neck, also called the dental cervix, sits between the crown and root. The jaw bone, also called the alveolar bone, is the bone that contains the tooth sockets and surrounds the teeth’s roots it holds the teeth in place. Blood vessels supply the periodontal ligament with nutrients, while nerves help control the amount of force used when you chew. Along with the cementum, the periodontal ligament connects the teeth to the tooth sockets. It contains both nerves and blood vessels. The periodontal ligament is made of connective tissue and collagen fiber. It’s connected to the periodontal ligament. Also called cement, this bone-like material covers the tooth’s root. The root canal is a passageway that contains pulp. It makes up approximately two-thirds of the tooth. It would also be feasible to introduce additional alphabetic characters or other symbols, for example to denote supernumerary teeth or bridge pontics, to which a purely numerical method such as the FDI system does not lend itself easily.The root is the part of the tooth that extends into the bone and holds the tooth in place. One advantage of Palmer notation is that it can produce a very graphical image, akin to a 'map' of the dentition tooth transpositions or edentulous spaces can easily be depicted if desired. On a standard keyboard 'slash' and 'backslash' may be used as a crude approximation to the symbols with numbers placed before or afterwards hence 3/ is 3┘ and /5 is ┌ 5 With the move from written dental notes to electronic records, some difficulty in reproducing the symbols has been encountered. The designations "left" and "right" on the chart, however, nonetheless correspond to the patient's left and right, respectively. patient's right corresponds to notation chart left. Orientation of the chart is traditionally "dentist's view", i.e. Hence the left and right maxillary central incisor would have the same number, "1", but the right one would have the symbol, "┘", underneath it, while the left one would have, "└". ![]() Adult teeth are numbered 1 to 8, with deciduous (baby) teeth indicated by a letter A to E. The Palmer notation consists of a symbol (┘└ ┐┌) designating in which quadrant the tooth is found and a number indicating the position from the midline. This makes it less confusing and less prone to errors in interpretation. Adult teeth were numbered 1 to 8, and the child primary dentition (also called deciduous, milk or baby teeth) were depicted with a quadrant grid using Roman numerals I, II, III, IV, V to number the teeth from the midline. It was originally termed the Zsigmondy system after the Hungarian dentist Adolf Zsigmondy who developed the idea in 1861, using a Zsigmondy cross to record quadrants of tooth positions. Although supposedly superseded by the FDI World Dental Federation notation, it overwhelming continues to be the preferred method used by dental students and practitioners in the United Kingdom. Palmer notation is a system used by dentists to associate information to a specific tooth.
