Location and Position - The maxillary second molar is located distally from the maxillary first molars. - It is mesial to the maxillary third molars. - In deciduous teeth, it is the last tooth in the mouth. - The permanent maxillary second molar does not have a third molar behind it. - Its position allows for efficient grinding during mastication.

Function and Anatomy - The primary function of the maxillary second molar is grinding during chewing. - There are usually four cusps on maxillary molars, two on the buccal side and two on the palatal side. - The deciduous maxillary second molar is more likely to have an oblique ridge compared to permanent molars. - The permanent maxillary molars do not have any teeth that precede them. - Despite similarities in function, there are significant differences between deciduous and permanent maxillary molars.

Notation for Deciduous Maxillary Second Molars - In the universal system of notation, the right deciduous maxillary second molar is designated as A, and the left one as J. - The international notation uses numbers, so the right deciduous maxillary second molar is known as 55, and the left one as 65.

Notation for Permanent Maxillary Second Molars - In the universal system of notation, the right permanent maxillary second molar is designated as 2, and the left one as 15. - The Palmer notation uses a number with a symbol to indicate the quadrant. Both second molars would have the number 7, but the right one would have the symbol ┘, and the left one would have └. - The international notation assigns the right permanent maxillary second molar as 17, and the left one as 27.
