molar (M)

[mō′lər]
Etymology: L, moles, mass
1 any of the 12 teeth, 6 in each dental arch, located posterior to the premolars. The crown of each molar is nearly cubical, convex on its buccal and lingual surfaces, and flattened on its surfaces of contact. Each of the upper molars can have three roots. The roots of each third upper molar are often fused. The lower molars are larger than the upper, and each has two roots. The roots of each third lower molar tend to fuse. Molars are used to crush and grind food.
2 (M) pertaining to the concentration of a solution, expressed as the number of moles of solute per liter of solution. See also mole2.

molar,

n 1. a reference solution in which the concentration is stated with regard to the number of gram molecular weights per liter of solution.

molar, mulberry,
n a malformed first molar with a crown, suggesting the appearance of a mulberry. It may be a manifestation of congenital syphilis, although other diseases affecting the enamel organ during morphodifferentiation may produce a similar lesion.

molars, second,

molar tooth cutter
long-handled, heavily constructed cutter, usually with a double-action scissor system of closing. The chisel-edged blades face each other and are brought together in parallel. They are operated from outside the mouth of the anesthetized horse and are sufficiently powerful to remove a protruding piece of tooth.

Segundo Moyers (1991), a perda prematura de qualquer dente decíduo pode facilitar a erupção precoce de seu sucessor permanente, ou retardá-lo de acordo com o estágio de formação dentária; além disso, o efeito da perda prematura dos primeiros molares decíduos não constitui grande importância clínica em relação à diminuição do perímetro do arco, mas a perda do segundo molar decíduo favorecerá a mesialização do primeiro molar permanente, principalmente se este não estiver irrompido quando ocorreu a perda prematura do molar decíduo.
