| molar | <mechanics> Of or pertaining to a mass of matter; said of the properties or motions of masses, as distinguished from those of molecules or atoms. Origin: L. Moles mass. <anatomy> Any one of the teeth back of the incisors and canines. The molar which replace the deciduous or milk teeth are designated as premolars, and those which are not preceded by deciduous teeth are sometimes called true molars. See Tooth.

| molar tooth | A tooth having a somewhat quadrangular crown with four or five cusps on the grinding surface; the root is bifid in the lower jaw, but there are three conical roots in the upper jaw; there are six molars in each jaw, three on either side behind the premolars in the permanent dentition; in the deciduous dentition there are but four molars in each jaw, two on either side behind the canines. Synonym: dens molaris, cheek tooth, molar, multicuspid tooth. (05 Mar 2000) |
