Case Report/Clinical TechniquesRoot Canal Treatment in a Mandibular Second Premolar with Three Root Canals

Case Report
A 31-yr-old Caucasian female patient was referred by her general dental practitioner for root canal treatment on a mandibular right second premolar. The reason for endodontic treatment was a symptom free necrotic pulp under a leaking composite filling with caries. The referring dentist initiated root canal treatment and succeeded in negotiating a distal root canal at a length of 24 mm. A calcium hydroxide paste was placed in the root canal. A cotton pellet was placed in the coronal third of the
DISCUSSION
The variability of the root canal system represents a challenge to both endodontic diagnosis and treatment. The identification of the internal morphology as precisely as possible is the primary step in root canal treatment. The only way to detect root canal morphology and anatomy is the use of proper preoperative radiographs. To enhance interpretation and alter the X-ray interpretation is to vary either the vertical or the horizontal cone angulation. Moreover, the sudden change in radiographic
CONCLUSION
Root canal treatment was carried out successfully and the 2-yr follow-up confirmed adequate healing without any complications.
In the cases where radiographic images are not clear or incomplete and do not help to predict exact root canal anatomy or root canal aberrations, it is recommended that magnification devices are used. Enhancement of color contrast by means of dye may also help to better visualize deeply situated orifices and aberrations when magnification alone does not suffice. In
