Clinical evaluation of color change and tooth sensitivity with in-office and home bleaching treatments.

Background: Among the number of vital bleaching techniques currently available to the clinicians, home bleaching and in-office bleaching are widely used in dental practice.

Aim And Objectives: The aim of this in vivo study was to compare the clinical performance, durability, and related tooth sensitivity with two vital bleaching procedures (in-office and at-home bleaching), in a split-mouth design.

Patients And Methods: Thirty adult participants having teeth shade mean of A2 or darker were selected for the study.

Effect of obturating materials on fracture resistance of simulated immature teeth.

Aim: The aim of this study was to evaluate the fracture resistance of simulated immature teeth, when the root canals were completely filled either with mineral trioxide aggregate (MTA) or Biodentine, comparing with that of roots filled with apexification procedure.

Materials And Methods: Sixty mandibular premolar teeth with single, straight canals decoronated at cementoenamel junction were divided into five groups ( = 12 each). Group 1 samples served as negative control and remaining four groups root samples were shaped and cleaned using ProTaper rotary files.
