Root And Canal Morphology Of Maxillary Premolar Teeth In An Egyptian Subpopulation Using Two Classification Systems: A Cone Beam Computed Tomography Study, Shehabeldin Mohamed Saber Prof.Dr.

Dentistry

Aim: To investigate the number of roots and root canal configurations using two coding systems and the root canal diverging and merging levels in extracted maxillary premolars in an Egyptian subpopulation using cone beam computed tomography (CBCT). Methodology: A total of 700 maxillary premolars were examined using CBCT in an Egyptian subpopulation. The number of roots was identified, and root canal configurations were classified according to Vertucci's classification and a new system for classifying root and canal morphology. In addition, the position where roots bifurcated and the levels where canals merged or diverged were identified. Fisher's exact test and independent …

Postoperative Pain After Single Visit Root Canal Treatment Using Multiple Rotary Files And Single Reciprocating File Instrumentation Techniques In Asymptomatic Mandibular Molars With Necrotic Pulps: A Randomized Control Clinical Trial, Mostafa M.A. Elkholy, Kariem M. El Batouty, Ehab Hassanein

Dentistry

Aim This prospective clinical study compared postoperative pain following single visit root canal treatment in patients with asymptomatic mandibular molar teeth with necrotic pulps using two different instrumentation techniques: multi-file rotary (ProTaper Universal), and reciprocating single-file (WaveOne) techniques.

Methodology Forty patients, who fulfilled specific inclusion criteria were randomly and equally assigned to 2 groups according to the root canal instrumentation technique used. All treatments were performed in one appointment. Patients were asked to complete a numerical rating scale (NRS) for recording pain levels at 6, 12, 24, 72 h and at 1 week postoperative intervals. In addition, the Face Pain …
