Digital scan over dental dam: workflow for successful clinical outcome.

Although the use of intraoral scanners is becoming more popular, dental professionals are still presented with the challenge of obtaining precise imaging of the preparation margins. Deep preparation margins, saliva contamination, or bleeding during the scanning procedures can impair the accuracy of the digital scan. Dental dam placement can significantly improve the quality and efficiency of the digital scan, while simultaneously providing a clean restorative field and serving as a barrier to the spread of infections for the protection of dental professionals.

Digital scanning under rubber dam: An innovative method for making definitive impressions in fixed prosthodontics.

Objective: To provide a comprehensive protocol for final impressions making under rubber dam isolation by using an intraoral scanner.

Clinical Consideration: Impression making after tooth preparation with rubber dam isolation are impossible with conventional physical impressions, which are not with intraoral scanners. Digital technologies have disrupted dentistry in the last decades, bringing new, straightforward, and more time-efficient protocols for dental practice.

Evaluation of Pink and White Esthetic Scores for Immediately Placed and Provisionally Restored Implants in the Anterior Maxilla.

Purpose: To evaluate the esthetic result of immediately placed implants with immediate provisional restorations in the anterior maxilla using the pink esthetic score (PES) and white esthetic score (WES).

Materials And Methods: The records of patients were evaluated retrospectively. The evaluation was carried out by two examiners using 12 evaluation criteria.

Reproducing Optical Properties of Anterior Teeth after Ultra-Conservative Preparation.

Objective: Selecting the appropriate material is essential when restoring color and appearance of esthetically compromised anterior teeth.

Clinical Considerations: Most of the conventional restorative techniques require tooth reduction in order to mimic optical properties of a natural tooth. Fortunately, bonding techniques associated with improvements on dental ceramics esthetics allow for highly conservative treatment options in which maximum preservation of dental tissues can be attained.

Fracture strength of flared bovine roots restored with different intraradicular posts.

Objective: The aim of this study was to evaluate the fracture strength and failure mode of flared bovine roots restored with different intraradicular posts.

Material And Methods: Fifty bovine incisors with similar dimensions were selected and their roots were flared until 1.0 mm of dentin wall remained.

A thermal investigation of dental bleaching in vitro.

Objective: Our goal was to investigate the surface temperature variations in the cervical region via infrared thermography, as well as the temperature within the pulp chamber via thermocouples, of mandibular incisors when subjected to dental bleaching using two different 35% hydrogen peroxide gels, red (HP) and green (HPM), when activated by halogen light (HL) and LED light.

Background Data: Temperatures increases of more than 5.5 degrees C are considered to be potentially threatening to pulp vitality, while those higher than 10 degrees C can result in periodontal injury.
