PULP CANAL MORPHOLOGY

The size of the pulp cavity is larger in which of the following?

• elderly individuals

• teeth with greater secondary dentin formation

• Young individuals

• calcified teeth

Continuous formation of secondary dentin throughout life is primarily regulated by which of the following cell types?

• Ameloblasts

• Odontoblasts

• Cementoblasts

• Fibroblasts

Which statement is most accurate about the relationship between cusp prominence and pulp horn development?

• larger cusps correspond to smaller pulp horns

• more prominent cusps usually have more prominent underlying pulp horns

• pulp horns develop independently of crown anatomy

• no specific relation

In multirooted teeth, which of the following best describes the anatomical separation of the pulp cavity?

• Each root has its own pulp chamber

• pulp chamber includes both coronal and radicular pulp

• root canal is considered the entire pulp cavity

• the pulp camber is the coronal portion, root canals are the radicular extensions

Presence of mamelons is often associated with

• irregular canal morphology

• deep pulp horns in the incisal region

• shallow root canals

• wider apical foramina

which of the following is associated with permanent pulp?

• enlarged apical foramens

• wider root canals

• flaring of root canals

• restricted apical foramen

Which anatomical feature of the maxillary permanent central incisor determines the shape of the pulp cavity?

• crown and root outline

• enamel thickness

• crown outline only

• cementoenamel junction
