Revisiting Premolars Using Cone-Beam Computed Tomography Analysis and Classifying Their Roots and Root Canal Morphology Using Newer Classification.

Objective: The objective is to compare the internal morphology of premolars while applying the Vertucci and recent classification system for root canal variations in the Gujarat population using CBCT.

Materials And Methodology:  A sample size of 537 CBCT images collected from various diagnostic centers in Gujarat was analyzed. The root canal morphology was then classified by using two methods - Ahmed et al.

The Clinical, Radiographic and Histological evaluation of three different concentrations of Formocresol as a pulpotomy agent.

Background: Formocresol, though the center of much controversy is still the most widely used medicament for primary teeth pulpotomy and an intracanal medicament which has undergone a lengthy evolution to shorten the formocresol application time and reduce the concentration of formocresol exposure to the pulp tissue. Hence, the determination of the actual effective dose and concentration of formocresol for clinical application in primary teeth is an important area of research and a thorough clinical, radiographic and histological investigation in human subjects is very much needed.

Materials & Methods: The study was conducted on 45 primary molars for the Clinical, Radiographic study and 45 premolars orthodontically indicated for extraction for the Histological study.
