How do you manage C-shaped canals?
Radiographic and clinical diagnoses can aid in identification and negotiation of the fan-shaped areas and intricacies of the C-shaped anatomy. Effective management of this anomalous canal configuration can be achieved with rotary and hand instrumentation assisted with sonics and ultrasonics.
What are the characteristics of a C-shaped canal?
The main anatomical feature of C-shaped canals is the presence of a fin or web connecting the individual root canals—the orifice may appear as a single ribbon-shaped opening with a 180° arc linking the two main canals (3).
How is C-shaped canal diagnosed?
CLINICAL DIAGNOSIS The pulp chamber in teeth with C-shaped canals may be large in the occlusoapical dimension with a low bifurcation. Alternatively, the canal can be calcified, disguising its C-shape. At the outset, several orifices may be probed that link up on further instrumentation (Fig.
Which of the following teeth is most likely to exhibit C-shaped morphology?
The C-shaped canal system may be observed in maxillary molars, maxillary and mandibular premolars, but most commonly detected in mandibular second molars.
What is the first molar?
The first molars are the first permanent teeth to erupt in the mouth and often play a pivotal role in the maintenance of the arch form and proper occlusal schemes.
How many canals are in a lower second molar?
Mandibular second molars usually have two roots with three root canals, two in the mesial root and one in the distal root; however, these teeth can present severe anatomical variations, such as the presence of three canals in the mesial root, two canals in the distal root, or supernumerary roots [2].
What is cusp of Carabelli?
The Cusp of Carabelli is a characteristic morphological trait often seen on the palatal surface of the mesiopalatal cusp of maxillary permanent molars and maxillary second deciduous molars [2].
Is it OK to remove first molar teeth?
Extraction of First Molars The permanent first molars are highly important in schemes of normal occlusion. However, in certain types of malocclusion cases, extraction of permanent first molars can be preferred over other teeth.
Is it OK to remove second molar?
It’s common for adults to lose a back molar, often to gum disease, tooth decay, or injury. Since back molars don’t affect the overall appearance of your smile, you might be tempted to skip replacing it. That’s not the best idea. Missing a tooth, even just one, can cause severe and permanent damage to your entire mouth.
What is a C-shaped canal configuration?
C-shaped canal configuration is a variation that has a racial predilection and is commonly seen in mandibular second molars. The intricacies present in this variation of canal morphology can pose a challenge to the clinician during negotiation, debridement and obturation.
What are the possible clinical problems associated with C-shaped canals?
C-shaped canal configurations present special clinical problems including relief of pain, copious bleeding, and difficulty in cleaning, shaping, and filling. A review of the literature, radiographic characteristics that make diagnosis possible before the canal is accessed, and suggestions for instrumentation and filling are provided here.
Is there a racial predilection for the C-shaped canal configuration?
The aim is to review and discuss the etiology, incidence, anatomic features, classification, diagnosis and management of the C-shaped canal configuration. C-shaped canal configuration is a variation that has a racial predilection and is commonly seen in mandibular second molars.
Where can I get a C-shaped endodontic canal?
1 Endodontic Section, Veterans Affairs Medical Center, 5901 East 7th Street, Long Beach, CA 90822, USA. C-shaped canal configurations present special clinical problems including relief of pain, copious bleeding, and difficulty in cleaning, shaping, and filling.
