Everything about The Maxillary First Molar totally explained
The
maxillary first molar is the
tooth located laterally (away from the midline of the
face) from both the
maxillary second premolars of the
mouth but mesial (toward the midline of the face) from both
maxillary second molars. The function of this
molar is similar to that of all molars in regard to grinding being the principle action during
mastication, commonly known as chewing. There are usually four
cusps on maxillary molars, two on the buccal (side nearest the cheek) and two palatal (side nearest the
palate). There may also a fifth smaller cusp on the palatal side known as the
Cusp of Carabelli. There are great differences between the
deciduous (baby) maxillary molars and those of the permanent maxillary molars, even though their function are similar. It is important to note that the permanent maxillary molars are not considered to have any teeth that precede it. Despite being named molars, the deciduous molars are followed by permanent premolars.
In the
universal system of notation, the deciduous maxillary first molars are designated by a letter written in uppercase. The right deciduous maxillary first molar is known as "B", and the left one is known as "I". The international notation has a different system of notation. Thus, the right deciduous maxillary first molar is known as "54", and the left one is known as "64".
In the universal system of notation, the permanent maxillary first molars are designated by a number. The right permanent maxillary first molar is known as "3", and the left one is known as "14". In the
Palmer notation, a number is used in conjunction with a symbol designating in which quadrant the tooth is found. For this tooth, the left and right first molars would have the same number, "6", but the right one would have the symbol, "┘", underneath it, while the left one would have, "└". The international notation has a different numbering system than the previous two, and the right permanent maxillary first molar is known as "16", and the left one is known as "26".
