| molar behaviour | <psychology> Behaviour described in large response units rather than smaller ones. Compare: molecular behaviour. (05 Mar 2000) |
| molar extinction coefficient | Absorbance (of light) per unit path length (usually the centimeter) and per unit of concentration (moles per liter); a fundamental unit in spectrophotometry. Synonym: absorbancy index, absorptivity, molar absorbancy index, molar absorptivity, molar extinction coefficient. (05 Mar 2000) |
| molar glands | Four or five large buccal glands in the neighborhood of the last molar tooth. Synonym: glandulae molares. (05 Mar 2000) |
| molar heat capacity | <chemistry> The amount of energy required to raise the temperature of one mole of a substance by one degree Celsius (or Kelvin). (09 Jan 1998) |
| molar mass | See: molecular weight. (05 Mar 2000) |
| molar pregnancy | Pregnancy marked by a neoplasm within the uterus, whereby part or all of the chorionic villi are converted into a mass of clear vesicles. (05 Mar 2000) |

| molar, third | The aftermost permanent tooth on each side in the maxilla and mandible. (12 Dec 1998) |
| 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) |
| mulberry molar | A molar tooth with alternating nonanatomical depressions and rounded enamel nodules on its crown surface, usually associated with congenital syphilis. (05 Mar 2000) |
| second molar | Seventh permanent or fifth deciduous tooth in the maxilla and mandible on either side of the midsagittal plane of the head following the arch form. (05 Mar 2000) |
| sixth-year molar | The first permanent molar tooth. (05 Mar 2000) |
| third molar | Eighth permanent tooth in the maxilla and mandible on each side, making it the most posterior tooth in human dentition; usually erupts between the seventeenth and twenty-third years; the roots are often fused, the separation being marked only by grooves; because it tends to erupt in an anterosuperior direction, the lower third molar often becomes impacted against the lower second molar; it is common for one or more third molar to fail to develop. Synonym: dens serotinus, molaris tertius, dens sapientiae, wisdom tooth. (05 Mar 2000) |
