The concept of no- or minimal-preparation veneers is more than 25 years old, yet there is no classification system categorizing the extent of preparation for different veneer treatments. The lack of veneer preparation classifications creates misunderstanding and miscommunication with patients and within the dental profession. Such a system could be indicated in various clinical scenarios and wo...

The degree of success in the elimination of bacteria during cavity preparation and prior to the insertion of a restoration may increase the longevity of the restoration and therefore the success of the restorative procedure. The complete eradication of bacteria in a caries-affected tooth, during cavity preparation, is considered a difficult clinical task. In addition to weakening the tooth stru...

Abstract The aesthetic result in the ceramic restoration of anterior teeth has always been a challenge clinical practice and, these cases, success depends on skills both clinician and dental technician. In current dentistry, main objective is to pursue results while preserving biological structures. Among various conservative techniques available for restorations, veneers are most advantageous,...

The purpose of this study was to compare, in vitro, by means of computerized analysis of digital radiographic images, the anatomic alterations produced in the mandibular molar tooth dentinal walls of mesiobucal canals with severe curvature by three different endodontic techniques: Progressive Preparation, Staged and Serial Preparation. A selection was made of 45 extracted, human, mandibular mol...

Traditionally, faculty assessment of preclinical crown preparations occurs by visualizing preparation features. However, contemporary CAD/CAM tools have the ability to more precisely evaluate preparation features, which is beneficial for psychomotor development. Taper is one of the most challenging features to objectively assess. The aim of this study was twofold: first, to validate the softwar...

When placing an indirect restoration such as a porcelain veneer, inlay, or onlay, the intaglio surface is typically treated in some fashion to ensure optimal bonding to the resin-based adhesives and luting cements required to affix it to the tooth tissues. A variety of surface preparation techniques have been advocated, including the use of acids, particle abrasion, various adhesives, and chemi...

Maxillectomy often leads to oralnasal or excessive oral-pharyngeal communication. The remaining teeth may need further preparation for various reasons, including crown or fixed dental prosthesis restoration. High-volume water is used in conjunction with highspeed tooth preparation to avoid the excessive heat generation that could endanger the health of the pulp. The water aerosol generated by t...

Coronal discoloration of endodontically treated teeth is a challenge in clinical dentistry. This study aimed to compare coronal induced by White Mineral Trioxide Aggregate and Calcium-enriched mixture cement. Fifty single-rooted, unrestored premolar extracted for orthodontic reasons were selected. After access cavity preparation, all the root canals instrumented with MTWO rotary files up #40.6%...

This paper aims to discuss the concept of canine guidance in light recent research with regard time extraction restored tooth, crowns representing worst performing restoration at 15 years (66% cumulative survival). Given that upper tooth may be considered 'cornerstone' arch, reasons for this poor performance are discussed by examination existing literature on and other aspects relating preparat...
