Cone beam computed tomography, labial access cavity
preparation, maxillary lateral incisor, root canal treatment, root dilaceration.
Caption: Figure 3: IOPA showing Root canals of 11 and 21 filled with Calcium hydroxide and iodoform (metapex) beyond the apex with the intention to resolve peri apical abscess and the access cavity
was restored with temporary restorative material
A small moist cotton pellet was placed over the MTA, and the access cavity
was sealed with temporary filling material.
Subjects of both groups underwent same procedure which included rubber dam isolation, access cavity
preparation and performing the preliminary filing of the canals.
The access cavity
was modified using a round bur (Dentsply- Maillefer, Ballaigues, Switzerland).
Inferior alveolar nerve block was considered successful if patient did not feel pain when cold test was performed after 45 min and on access cavity
After the biomechanical preparation, the root canals were dressed with Calcium Hydroxide (CaOH) paste and the access cavity
was sealed with a temporary restorative material.
In this procedure, the mixture was left in the pulp cavity for a few days, and the access cavity
was sealed with provisional cement.
17 A 25mm # 15 K file (Mani) was introduced into the tooth through the access cavity
till the point where the file just started to appear at the cervical border of the major foramen under 2.
preparation was performed by using Endo-Access diamond bur (Dentsply, Maillefer, Baillaigues, Switzerland).
1 It includes access cavity
preparation, canal instrumentation, irrigation, intracanal medication and root filling.
After the administration of local anesthesia and Rubber dam application, Access cavity
was made and canal location was done using magnifying loupes.
