Table 1. identification of teeth in old systems with new system (MICAP)
Tooth Class/TypesFDI SystemPalmer NotationUniversal SystemMICAP System
Maxillary right first premolar#14#4#5#1P
Mandibular right canine#43#3#27#1C
Maxillary left first molar#26#6#14#M1
Maxillary left third molar#28#8#16#M3
Maxillary right central incisor#11#1#8#1I
Maxillary left lateral incisor#22#2#10#I2
  • Note: Different numbers for the same tooth or vice versa may complicate the clinical scenario. For example, #14 is maxillary right first premolar (FDI system), and same digit is maxillary left first molar (universal system). Maxillary right first premolar in universal system is #5, and same tooth is #4 in Palmer notation. MICAP is simple, provides a unique identification, and differentiates clearly from other systems.
