| 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 solution | <chemistry> A solution made up of one mole of a compound in enough water to make a thousand millilitres of thesolution. (09 Oct 1997) |
| 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) |
| twelfth-year molar | The second permanent molar tooth. (05 Mar 2000) |
| first molar | First permanent molar, sixth permanent tooth or fourth deciduous tooth in the maxilla and mandible on either side of the midsagittal plane of the head following the arch form. (05 Mar 2000) |
