How do you Obturate C-shaped canals?
Obturation of C-shaped canals may require technique modifications. The mesiolingual and distal canal spaces can be prepared and obturated as standard canals. However, sealing the buccal isthmus is difficult if lateral condensation is the only method used.
What is 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.
Where is the location of C-shaped?
There is a presence of connecting slit which determines the location of “C” shape. If the buccal portion of the mesial and distal roots are fused, the slit goes through the area of fusion and so the “C” is close to lingual. If the lingual portion of the roots are fused, then the “C” is close to the buccal [11].
Which of the following teeth is most likely to exhibit C-shaped morphology?
Introduction. The C-shaped canal system may be observed in maxillary molars, maxillary and mandibular premolars, but most commonly detected in mandibular second molars.
What are the characteristics of a C shaped canal discuss your answer?
The main anatomic feature of C-shaped canals is the presence of a fin or web connecting the individual root canals. Roots containing a C-shaped canal often have a conical or square configuration (2, 3, 11).
What is Taurodontism of teeth?
Taurodontism is a developmental disturbance of a tooth in which body is enlarged at the expense of the roots. An enlarged pulp chamber, apical displacement of the pulpal floor and lack of constriction at the cementoenamel junction are the characteristic features. It appears most frequently as an isolated anomaly.
What are fins in root canal?
Authors studying roots with two canals commonly report an isthmus, fin, or corridor, which may be present between the two canals. Author Green has previously described this corridor as a “ribbon-shaped passage.” He had found that this ribbon-shaped passage is present in 22% of mandibular central and lateral incisors.
How do you identify taurodontism?
What is isthmus in tooth preparation?
The transition between the occlusal and proximal cavity is termed isthmus. This is the narrowest place of preparation and it is of fundamental significance for retention of the filling.
What is the ideal width of the isthmus?
The isthmus width is between 1/3 and ½ the labio-lingual intercuspal width of the tooth.
What is an isthmus in endodontics?
Root canal isthmus, a narrow ribbon-shaped communication between two root canals is an important anatomical feature because of the fact that it may contain pulp remnants, necrotic tissues, and micro-organisms and their byproducts.[1] An isthmus is also called a corridor, a lateral interconnection, and a transverse …
What causes Turner’s tooth?
If Turner’s hypoplasia is found in the anterior area of the mouth, the most likely cause is a traumatic injury to a primary tooth. The traumatized tooth, which is usually a maxillary central incisor, is pushed into the developing tooth underneath it and consequently affects the formation of enamel.
What is resistance and retention form?
He stated: “Resistance form is that shape given to a cavity intended to afford such a seat for the filling as will best enable it to withstand the stress brought upon it in mastication. Retention form is the provision for preventing it from being dislodged.”
What are marginal ridges?
An enamel elevation on the crown of a tooth which forms the mesial or distal border of the occlusal surface.
What is Turner’s spot?
Turner’s Tooth, also called Enamel Hypoplasia by professionals in the field, is a condition that reduces a tooth’s enamel thickness, increases tooth sensitivity, leaves the affected tooth more susceptible to decay, and results in an unsightly appearance.
What is a Cusp of Carabelli?
Put simply, the cusp of Carabelli is just an extra bump on one or two of your teeth. According to the Journal of Clinical and Diagnostic Research, these possibly form from overactivity of the dental lamina, one part of tooth development.
