Discovering our dental chart

A concept used by dentists, a dental chart is the numbering of permanent teeth. It makes it easy to locate the tooth(s) in the mouth that needs treatment. It has been around for several years and serves various roles for healthcare professionals. For patients, a dental chart helps them understand treatment estimates.

Teething

Until the age of 6, the dental pattern is very different; a child has 20 baby teeth spread over 4 quadrants of 5 teeth. As an adult, he or she has 32 permanent teeth spread over 4 quadrants of 8 teeth. Each quadrant is numbered from 1 to 8, starting from the middle to the back. For an adult, the number of central incisors ends with 1, that of lateral incisors with 2, that of canines with 3, that of permanent premolars and molars with 4 and 5, and that of permanent molars with 6, 7, and 8. For a child under 6, there is the central incisor, the lateral incisor, the canine, the 1st molar, and the ^2nd molar. The wisdom tooth is the 3rd molar, and it ends in 8. It is from this distribution that the dental chart appeared, and it gives each tooth a number (baby tooth or permanent tooth). The numbering is 2 digits, the first is the dial, and the second is the position of the tooth in relation to the center. In the absence of a tooth germ or agenesis, the dental chart is modified in the normal chronology, this is also the case when some baby teeth are never replaced. On average, between 6 and 12 years, baby and permanent teeth coexist together, and during this period, the dental chart considers the type of tooth to be identified in the numbering.

The importance of dental charting

The dental chart is universal, because to date, it is the easiest and safest way to identify a tooth. A tool for traceability, security and comfort, it is essential for oral health professionals in the exchange of information, but also for insurance companies, Social Security, mutual insurance companies, etc. Indeed, it helps avoid misunderstandings and minimize errors in written and verbal communications. Apart from the ethical obligation, the dental chart is established for each new patient. Its interest is multiple: the identification of victims, the settlement of disputes between the patient and the practitioner, proof for practitioners in the event of an expert appraisal, etc. For patients, it is a history of previous dental care. The dental chart is read from the front while looking at the patient. (you can discover our complementary article on the tooth chart: tooth chart )
