The first set of teeth in humans, consisting of 20 teeth.

Specific identifiable features on a tooth used for description.

The different sides of a tooth including buccal, lingual, mesial, and distal.

A system for identifying and recording primary teeth.

The timeline of when primary teeth appear in infants.

Begins around 3-4 months in utero.

Occurs at 4 months of age.

Typically erupts at 7.5 months.

Completed around 1.5 years of age.

Crown appears square; shorter and bulbous.

Crown is concave with pronounced marginal ridges.

Crown looks bulky with cervical undulation.

Begins at 4.5 months in utero.

Starts erupting at 8-9 months.

Upper lateral incisors are less square compared to centrals.

Timeline of upper canine tooth development stages: calcification, crown completion, eruption, root completion.

Initial calcification of the upper canine occurs at 5 months in utero.

Upper canine typically erupts between 16 to 20 months after birth.

Timeline for upper first molar: calcification at 5 months, crown completion at 6 months, eruption at 12-16 months.

Eruption of the upper first molar happens at 12 to 16 months of age.

The upper first molar has two buccal roots: mesio-buccal and disto-buccal.

The upper canine features a symmetrical crown with an enamel ridge creating fossae on either side.

The upper canine has one root with one canal and no pulp horns.

Has a large mesio-lingual and a small disto-lingual cusp.

Enamel ridge joining mesio-lingual and mesio-buccal cusps.

Forms a small mesial and a large distal fossa.

Two divergent roots: one mesial and one distal, flattened mesio-distally.

Contains three pulp horns: lingual, mesio-buccal, and disto-buccal.

Erupts around 1 ¾ to 2 ½ years of age.

Has three buccal cusps: mesio-buccal, disto-buccal, and distal.

Has four pulp horns, one for each cusp.

Initial calcification at 4 ½ months in utero, crown completion 4 months, eruption at 6 ½ months, root completion 1 ½-2 years.

Almost symmetrical with a sharp mesial incisal angle and rounded distal incisal angle.

Begins calcification at 4 ½ months, crown completion at 4 ½ months, erupts at 7 months, root completes in 1 ½-2 years.

Labial view shows a fan-shaped crown with a sharp mesio-incisal angle and a rounded disto-incisal angle.

Initial calcification at 5 months in utero, crown completion at 9 months, erupts between 16-20 months, root complete in 2 ½-3 years.

Labially convex crown with one root, triangular in cross-section, which curves distally and labially.

Initial calcification at 5 months, crown completion at 6 months, erupts from 12-16 months, root completes in 2-2 ½ years.

Buccal view has two cusps, mesio-buccal and disto-buccal; cervical region has a tubercle of Zuckerkandl.

The lower canine has one root canal and no pulp horns; root is roughly triangular.

Crown completion varies among teeth: 4 months for central incisor, 4 ½ for lateral incisor, 9 for canine, and 6 for first molar.

A bulge of enamel on the mesial aspect of the upper first molar.

The upper first molar typically has 3 root canals and 4 pulp horns.

The upper second molar erupts between 1¾ to 2½ years.

The upper second molar has 4 cusps: mesio-buccal, disto-buccal, mesio-palatal, and disto-palatal.

Upper second molar typically has 2 buccal roots and 1 palatal root.

In the upper second molar, the mesio-palatal cusp is the largest and the disto-palatal cusp is the smallest.

Initial calcification of the upper second molar occurs at 6 months in utero.

The upper second molar has 4 pulp horns.
