What is the FDI notation for the tooth charted as lower left first deciduous molar in the Palmer charting system?

In the FDI notation system, the first digit represents the quadrant of the mouth, and the second digit represents the specific tooth within that quadrant. In this case, the "lower left first deciduous molar" corresponds to the first quadrant in the lower left section of the mouth.

For deciduous teeth, the FDI notation uses numbers 5 to 8 for the primary molars. The lower left quadrant is designated as 7, and the first deciduous molar is classified as 4. Therefore, when combined, the correct FDI notation for the lower left first deciduous molar becomes 74.

In summary, the answer highlights the proper identification of the tooth within the framework of the FDI system by correctly applying the quadrant and tooth number, making it significant for maintaining clarity and accuracy in dental records and communications.
