[The importance of a fixed dental notation system within the dental clinic].

A teenager began an orthodontic treatment. During his orthodontic treatment, the orthodontist refferd the teenager to an Oral and maxillofacial surgeon to extract tooth no. 25. The orthodontist used the Palmer notation method to mark the tooth - 5 - and the Oral and maxillofacial surgeon read it as the no. 15, which is a completely different tooth according to the FDI World Dental Federation notation system. As a result, the Oral and maxillofacial surgeon extracted a healthy tooth by mistake. The teenager submitted a claim in tort for the harm he had suffered as a result of the mistake.
