lingual development groove

Occlusal View - Primary Maxillary Second Molar The transverse groove of the oblique ridge crosses the oblique ridge and connects the?

central pit with the distal pit

Distal View

Distal View - Primary Mandibular First Molar The facial crown outline is lingually positioned _______________, in comparison to the ___________

DF cusp, MF cusp

Distal View - Primary Mandibular First Molar The height of curvature of the cervical line is

Distal View - Primary Mandibular First Molar What roots are visible form this view?

Both

Distal View - Primary Mandibular First Molar The distal root slightly converges?

To the apex

Distal View - Primary Mandibular First Molar There is a developmental root surface depression on the?

Distal

Ecoptic Eruption

- A condition that is exhibited when a tooth erupts or emerges in the wrong position within the arch. - Usually seen in the F or L direction

Maxillary lateral incisors are ectopically erupted towards?

primarily the lingual side

Maxillary canines are ectopically erupted towards?

the facial side

A tooth is a different position then it is suppose to be

Transposition (seen in canines - maxillary the most)

Most common rotated tooth

maxillary second premolar > maxillary incisor > maxillary first premolar

Dens-in-Dente

Also known as dens invaginatus, is a condition found in permanent teeth - the outer enamel surface is folded inward - tissue is wrapped like a croissant

What for of dens-in-dente exist?

coronal and radicular

What is dens-in-dente considered?

a malformation of teeth probably resulting from an infolding of the dental papilla during tooth development

What tooth typically displays dens-in-dente?

maxillary lateral incisor

Dentinogenesis Imperfecta

Condition causes teeth to be discolored (most often a blue-gray or yellow-brown color) and may present with a translucent apperance

The teeth of dentinogenesis imperfecta

teeth have a weaker construct than normal teeth, making them prone to degradation and eventual loss - can affect both permanent and primary

Radiographically dentinogenesis imperfecta

exhibit a partial or total absence of pulp chambers and root canals

Facial Aspect Measurement & Geometry - Permanent Maxillary Central Incisor The __________ length (10.5 mm) is greater than the _________ width (8.5 mm) which is greater than the _________ depth (7.0mm)

CI > MD > FL

Facial Aspect Measurement & Geometry - Permanent Maxillary Central Incisor Crown outline?

Trapezoid with the shorter parallel side at cervix

are greater than at cervix

Lingual Aspect - Permanent Maxillary Central Incisor The cervical outline is more ____________ that what is seen on the ____________ aspect

apically-positioned, facial

Lingual Aspect - Permanent Maxillary Central Incisor The lingual fossa in the incisal one-half of the crown surface is described as?

wide, shallow "dish-shaped" depression

Lingual Aspect - Permanent Maxillary Central Incisor The lingual fossa is what shape?

trapezoidal

Lingual Aspect - Permanent Maxillary Central Incisor Explain the cingulum?

- well developed in the cervical 1/2 - often has two ridge projections that impinge on the lingual fossa in the middle third - greatest curvature lingually of the cingulum and the crest of the cervical line gingival will be slightly distal to the MD long axis bisector of the crown
