Prof. İzim TÜRKER KADER Formulae for Mammalian Dental Formula The denomination and number of all mammalian teeth are expressed by formulae that are used to differentiate the human dentitions from those of other species. Dental Notation Systems & Parts of the Tooth DENT1001 Dental Anatomy © Assist. Prof. İzim TÜRKER KADER Formulae for Mammalian The denomination of each tooth is often represented by the initial letter in its name (e.g., I for incisor, C for canine, P for premolar, M for molar). Dental Notation Systems & Parts of the Tooth DENT1001 Dental Anatomy © Assist. Prof. İzim TÜRKER KADER Formulae for Mammalian Each letter is followed by a horizontal line and the number of each type of tooth is placed above the line for the maxilla (upper jaw) and below the line for the mandible (lower jaw). The formulae include one side only, with the number of teeth in each jaw being the same for humans. Dental Notation Systems & Parts of the Tooth DENT1001 Dental Anatomy © Assist.

As a general rule, mandibular deciduous teeth normally precede their maxillary counterparts in eruption. It can also be said that the deciduous teeth normally erupt in order from the front of the mouth toward the back, even though the canines in each quadrant normally erupt after the first molars.

Prof. İzim TÜRKER KADER Tooth Numbering Systems Dental Notation, is the systematic naming of the teeth in a dentition consisting of numbers, letters or symbols used to indicate their place in the mouth and instead of writing their names clearly (Dens incisivus lateralis, right mandibular central deciduous incisor) Dental Notation Systems & Parts of the Tooth DENT1001 Dental Anatomy © Assist. Prof. İzim TÜRKER KADER  Tooth Numbering Systems Universal (American) Notation The numbering system which enjoys the widest use in the US is the universal system. It employs a different number (1-32) in a consecutive arrangement for all permanent teeth, and a number- letter (ld-20d) for each of the deciduous teeth.

Prof. İzim TÜRKER KADER  Tooth Numbering Systems Zsigmondy (Palmer) Notation; The symbolic system for the permanent dentition was introduced by Adolph Zsigmondy of Vienna in 1861 and then modified for the primary dentition in 1874. Independently, Palmer also published the symbolic system in 1870. The symbolic system is most often referred to as the Palmer notation system in the United States and less frequently as the Zsigmondy/Palmer notation system.
