| cusp angle | The angle made by the slopes of a cusp with the plane which passes through the tip of the cusp and which is perpendicular to a line bisecting the cusp, measured mesiodistally or buccolingually, the angle made by the slopes of a cusp with a perpendicular line bisecting the cusp, measured mesiodistally or buccolingually, one-half of the included angle between the buccal and lingual or mesial and distal cusp inclines.

| cusp height | The shortest distance between the tip of a cusp and its base plane, the shortest distance between the deepest part of the central fossa of a posterior tooth and a line connecting the points of the cusps of the tooth. Facial height, the linear dimension in the midline from the hairline to the menton. Nasal height, the distance between the nasion and the lower border of the nasal aperture. Orbital height, the distance between the midpoints of the upper and lower margins of the orbit. (05 Mar 2000) |
| cusp of Carabelli | A fifth cusp found on the maxillary first molars, usually located lingual to the mesiolingual cusp. (05 Mar 2000) |
| cusp of tooth | An elevation or mound on the crown of a tooth making up a part of the occlusal surface. Synonym: cuspis dentis, cuspis coronae. (05 Mar 2000) |
| semilunar cusp | One of the three semilunar segments serving as the three cusps of a valve preventing regurgitation at the beginning of the aorta; a similar valve guards the entrance of the pulmonary trunk; the segments are named, respectively, anterior, right, and left in the pulmonary valve, and posterior, right, and left in the aortic valve.

| talon cusp | An anomalous cusp that projects lingually from the cingulum of permanent incisors. Origin: Eng. Claw, heel, fr. O. Fr., fr. L. Talus, ankle (05 Mar 2000) |
| tricuspid | 1. Having three cusps, or points; tricuspidate; as, a tricuspid molar. 2. <anatomy> Of or pertaining to the tricuspid valves; as, tricuspid obstruction. <anatomy> Tricuspid valve, the valve, consisting of three triangular membranous flaps, at the opening of the right auricle into the right ventricle in the heart of most mammals; sometimes called the tricuspid valves, each flap being regarded as a valve. Origin: L. Tricuspis, -idis; tri- (see Tri-) + cuspis a point: cf. F. Tricuspide. Source: Websters Dictionary (01 Mar 1998) |
| tricuspid area | The region of the chest wall over the lower part of the body of the sternum, where the sounds produced at the tricuspid valve are heard most distinctly. (05 Mar 2000) |
| tricuspid atresia | Absence of the orifice between the right atrium and ventricle, with the presence of an atrial defect through which all the systemic venous return reaches the left heart. As a result, there is left ventricular hypertrophy (hypertrophy, left ventricular) because the right ventricle is absent or not functional. (12 Dec 1998) |
| tricuspid incompetence | Defective closure of the tricuspid valve permitting regurgitation into the right atrium during systole. (05 Mar 2000) |
| tricuspid insufficiency | See: valvular insufficiency. (05 Mar 2000) |
| tricuspid murmur | A murmur produced at the tricuspid orifice, either obstructive or regurgitant. (05 Mar 2000) |
| tricuspid orifice | An atrioventricular opening which leads from the right atrium into the right ventricle of the heart. Synonym: ostium atrioventriculare dextrum, ostium venosum cordis. (05 Mar 2000) |
| tricuspid stenosis | Pathologic narrowing of the orifice of the tricuspid valve. (05 Mar 2000) |
| tricuspid tooth | A tooth having a crown with three cusps. (05 Mar 2000) |
