Convex – išgaubimas; Convex functions play an important role in many areas of mathematics Cingulum – emalio ketera danties karūnėlėje In zoology cingulum refers to this feature only in the upper teeth Slope – šlaitas  The distal cusp slope is longer than the mesial cusp slope.

Covered with enamel; Visible part; Above the gingiva; Various shapes.

Embedded in the jaw; Normally not visible; The number varies individualy.

The hardest substance in the body; Translucent; Can not regrow; Damage – painless;.

Calcium and phosphate ions; Proteins – enamelins; Water.

Hard and porous tissue; Underneath the enamel and cementum; Can regenerate; Chemical composition: 70% inorganic matter; 30% organic matter and water.

Soft tissue; Pulp chamber -> radicular pulp; Pulp contains: Odontoblasts; Cells for dentin creation; Nerves, vessels.

Bone-like tissue; Covers the roots; Chemical composition: 55% organic material; (mainly collagen); 45% inorganic material (mainly calcium salts);.

Central and lateral; One root; Chisle-shaped; Sharp; Function - cutting food.

Flat and thin; Closest to midline; Larger than lateral; No cusps, only ridges. Biting, cutting, shearing food; The support for lip shape; Certain sounds pronounciation (eg. ‘t’, ‘th’).
