Q

Explain how a tooth can be divided into 3rds for surface descritpion?

A

For purposes of description, the crowns and roots of teeth have been divided into thirds, and junctions of the crown surfaces are described as line angles or point angels

Q

What is the ridge? (tooth surfaces)

A

The linear elevation onthe surface of a tooth andis named according to itslocation

17
Q

What is the Marginal Ridge? (tooth surfaces)

A

The rounded borders of the enamels that form the proximal margins of the occlusal surfaces of premolars and molars and the proximal margins of the lingual surfaces of the anterior teeth

18
Q

What is the Tubercle? (tooth surfaces)

A

A smaller elevationon some portion of the crownproduced by an extraformation of enamel (deviationsform the typical form)

19
Q

What is the Cingulum? (tooth surfaces)

A

Lingual lobe of an anterior tooth. It makes up the bulk of the cervical third of the lingual/palatal surfaces

20
Q

What is the Lobe? (tooth surfaces)

A

One of the primarysections of formation in thedevelopment of the crown

21
Q

What is the Mamelon? (tooth surfaces)

A

Any one of the threerounded protuberances foundon the incisal ridges of newlyerupted incisor teeth

22
Q

What are the triangular ridges? (tooth surfaces)

A

Descend from the tips of the cusp of posterior teethtowards the central part of the occlusal surfaces. They are named after thecusps to which they belong(behind the front teeth)

23
Q

What is the transverse ridge? (tooth surfaces)

A

The union of two triangular ridges crossingtransversely the surface of a posterior tooth

24
Q

What is the oblique ridge? (tooth surfaces)

A

a ridge crossing obliquely the occlusal surfaces of maxillarymolars and formed by the union of the triangular ridge of the distobuccal (DB) cusp and the distal cusp ridge of the mesiopalatal (MP) cusp

25
Q

What is the Fossa? (tooth surfaces)

A

Irregular depression or concavity

26
Q

What is the lingual fossa? (tooth surfaces)

A

Lingual surfaces ofincisors

27
Q

What is the central fossae? (tooth surfaces)

A

Occlusal surface ofmolars. Formed by the convergence of ridges termination at a central point in the bottom of the depression where there is ajunction of grooves

28
Q

What is the triangular fossae? (tooth surfaces)

A

Found on occlusalsurfaces of posterior teeth mesial or distal to marginal ridges. Sometimes on palatalsurfaces of maxillary incisors at the edge of the lingual fossae where the marginal ridge (MR) and the cingulum (CI) meet

29
Q

What is the sulcus? (tooth surfaces)

A

The long depression or valley in the surface of a tooth between ridges andcusps, the inclines of which meet at an angle. A sulcus has a developmental groove at the junction of its inclines

30
Q

What is the developmental groove? (tooth surfaces)

A

Shallow groove or line between the primary parts of the crown or root

31
Q

What is the supplemental groove? (tooth surfaces)

A

Shallow lineardepression on the surface of a tooth (Supplemental to a developmental grooveand does not mark the junction of primaryparts)

32
Q

What is a pit? (tooth surfaces)

A

Small pinpoint depression located at the junction of developmental grooves orat terminals of those grooves.
