Universal notation systemUniversal notation systemADA officially recommended the Universal system in ADA officially recommended the Universal system in

1968. In this system for the permanent dentition 1968. In this system for the permanent dentition the maxillary teeth are numbered through 1 to 16 the maxillary teeth are numbered through 1 to 16 beginning with upper right third molar. The beginning with upper right third molar. The mandibular teeth are numbered through 17 to 32 mandibular teeth are numbered through 17 to 32 beginning with lower left third molar. The universal beginning with lower left third molar. The universal system notation for primary dentition utilises upper system notation for primary dentition utilises upper case alphabets. case alphabets.
