| endogenous creatinine clearance | A term distinguishing measurements based on the creatinine normally present in plasma; since no infusion is necessary, an average value may be obtained by collecting urine for a long period, e.g., 24 hours. (05 Mar 2000) |
|---|---|
| exogenous creatinine clearance | A term distinguishing measurements based on infusing creatinine intravenously to raise its plasma concentration and facilitate its accurate chemical determination. (05 Mar 2000) |
| urea clearance | The volume of plasma (or blood) that would be completely cleared of urea by one minute's excretion of urine; originally calculated as urine flow multiplied by urine urea concentration divided by concentration of urea in whole blood rather than plasma, representing blood urea clearance rather than plasma urea clearance. (05 Mar 2000) |
| urea clearance test | A test of renal function based on urea clearance. (05 Mar 2000) |
| free water clearance | The amount of water excreted in the urine beyond that which would accompany the excreted solutes if the urine were isosmotic with plasma; it represents the loss of body water in excess of solute tending to raise body osmolality and making urine hyposmotic. Unlike other clearance's, it is calculated by subtracting the osmolal clearance from the actual volume of urine excreted per minute. A negative value for free water clearance represents the amount of water that the body has reclaimed from isosmotic tubule fluid to make the urine hyperosmotic and to lower body osmolality.

| axio-occlusal | Pertaining to the line angle formed by the junction of the axial and occlusal walls of a tooth. (05 Mar 2000) |
| balancing occlusal surface | The contact's between upper and lower dentures on the balancing or mediotrusive side for the purpose of stabilizing the dentures, the contact's between upper and lower dentures at the opposite side from the working or laterotrusive side (anteroposteriorly or laterally) for the purpose of stabilizing the dentures, the contact's between upper and lower natural or artificial teeth at the opposite side from the working or laterotrusive side. Synonym: balancing occlusal surface. (05 Mar 2000) |
| bucco-occlusal angle | The line of junction of the buccal and occlusal surfaces of a tooth. (05 Mar 2000) |
| generated occlusal path | A registration of the path's of movement of the occlusal surfaces of mandibular teeth on a plastic or abrasive surface attached to the maxillary arch. See: functional chew-in record. (05 Mar 2000) |
| mesiobucco-occlusal | Relating to the angle formed by the junction of the mesial, buccal, and occlusal surfaces of a bicuspid or molar tooth. (05 Mar 2000) |
| mesiolinguo-occlusal | Denoting the angle formed by the junction of the mesial, lingual, and occlusal surfaces of a bicuspid or molar tooth. (05 Mar 2000) |
| mesio-occlusal | Denoting the angle formed by the junction of the mesial and occlusal surfaces of a bicuspid or molar tooth. (05 Mar 2000) |
| working occlusal surfaces | The surface's of teeth upon which mastication can occur. (05 Mar 2000) |
| deflective occlusal contact | A condition of tooth contact's which diverts the mandible from a normal path of closure to centric jaw relation. Synonym: cuspal interference, interceptive occlusal contact, premature contact. (05 Mar 2000) |
| denture occlusal surface | That portion of the surface of a denture that makes contact or near contact with the corresponding surface of an opposing denture or tooth. Synonym: facies occlusalis dentis, facies masticatoria, grinding surface, masticating surface, masticatory surface, occlusal surface. (05 Mar 2000) |
