Root Canal System And Access Prep Flashcards
It is where the canal is pulp is located and found at the center of the tooth
Root canal system
It houses the coronal portion of the pulp
Pulp chamber
Pulp chamber consists of: (2)
Pulp horn
Root canal orifices
It is located directly below the cusp
Pulp horn
It is found at the floor of the pulp chamber
Root canal orifice
It is the floor of the pulp chamber and the roof of the root canal
Root canal orifice
It is the part of pulp that is housed by the anatomical root
Root canal
Root canal consists of: (3)
Root main canal
Lateral canals
Furcation canal
These are canals that are found at the sides of the main root canal
Lateral canals
These are canals found in the furcation
Furcation canals
What are the structures found at the apical 3rd of the root canal?
Apical foramen
Apical delta
Accessory foramina
This is the main exit point of the pulp
Apical foramen
This is the area occupying in between the apical foramen and accessory foramina
Apical delta
These are other exit points of the pulp and it is not limited to the apex
Accessory foramina
The shape of the root canal system corresponds to the:
Cross-sectional shape of the roots
It is found at the cervical third of the crown
Pulpal roof
It is found at the cervical third of the root
Pulpal floor
It is yellowish in color since it is made up of dentin
Pulpal roof
It is dark in color
Pulpal floor
It has no dentinal map
Pulpal roof
It has presence of dentinal map
Pulpal floor
It has no definite shape
Pulpal roof
It is smooth and convex but to completely flat
Pulpal floor
What are the 6 methods of studying root canal anatomy
Ground section
Histologic
Radiographic
Clearing technique
Acrylic cast/silicone injection
Computerized method
It is the method of studying the root canal anatomy by thinning down the tooth structure longitudinally or cross-section
Ground section
It is the method of studying root canal anatomy by decalcifying ground section using hydrochloric acid and is thinned down using microtomes
Histologic
It is a method of studying root canal anatomy by injecting root canal with methylene blue and cleared with methyl methacrylate
Clearing technique
It is a method of studying root canal anatomy by Injecting fast setiing fluid acrylic then the tooth is split to expose the hardened impression
Acrylic cast/silicone injection
What are the factors that affect root canal morphology?
Age
Caries
Developmental anomalies
Irritants
Attrition
Abrasion
Erosion
Trauma
Clinical procedures
