Preservation of Posterior Mandibular Extraction Site with Allogeneic Demineralized, Freeze-Dried Bone Matrix and Calcium Sulphate Graft Binder before Eventual Implant Placement: A Case Series
Demineralized, freeze-dried bone matrix mixed with calcium sulphate graft binder was used for bone reconstruction at an extraction site before implant placement in 3 patients. Advantages and disadvantages of this approach are discussed. Read more
Dimensional Accuracy of 2 Irreversible Hydrocolloid Alternative Impression Materials with Immediate and Delayed Pouring
Two irreversible hydrocolloid alternative impression materials exhibited minimal dimensional changes with immediate and delayed pouring, differing statistically from a traditional impression material but still meeting established clinical standards. Read more
Esthetic Rehabilitation of Anterior Teeth with Porcelain Laminates and Sectional Veneers
This clinical report describes application of porcelain laminates and sectional veneers by a minimally invasive method, including a step-by-step protocol for cementation of these delicate restorations. Read more
Evaluation of Ocular Hazards from 4 Types of Curing Lights
Four curing lights were tested to assess the risk of ocular damage to dental practitioners. Effective UV irradiance was minimal, and maximum permissible daily exposure limits exceeded 8 hours. Read more
Classification of Extensively Damaged Teeth to Evaluate Prognosis
The detailed criteria and guidelines for assessment of severely damaged teeth provided in this article will help dentists avoid errors and develop an appropriate treatment plan. Read more
Inlay-Retained Zirconia Fixed Dental Prostheses: Modified Designs for a Completely Adhesive Approach
Although full-coverage metal–ceramic FDPs may be the standard for tooth replacement, inlay-retained all-ceramic FDPs offer many advantages, including less tissue loss. Read more
Fracture Resistance of 3 Types of Primary Esthetic Stainless Steel Crowns
In vitro testing revealed that esthetic stainless steel crowns are capable of resisting typical pediatric occlusal forces over short clinical periods. Read more
Effects of External Bleaching on Restorative Materials: A Review
Bleaching with peroxide agents may alter the surface roughness, microhardness or colour of some restorative materials. Patients should be made aware of these potential changes and the possibility that their restorations may need polishing or replacing after bleaching procedures. Read more
Effect of Distance on Irradiance and Beam Homogeneity from 4 Light-Emitting Diode Curing Units
Quantitative analysis of irradiance and beam homogeneity from 4 curing lights revealed differences between units and changes with increasing distance. These results have implications for the adequacy of curing of deep restorations. Read more
Surface Characteristics of Zirconia-Based Posterior Restorations: Clinical and Scanning Electron Microscopic Analysis
Zirconia-based posterior fixed dental prostheses were reliable over the medium term (4 years). However, surface alterations of the veneering ceramics could cause subsequent clinical problems. Read more
Orthodontic Alignment and Extrusion of a Periodontally Involved Lateral Incisor: Audiovisual Presentation
This audiovisual case report guides dentists through an orthodontic alignment and extrusion of a periodontally involved lateral incisor in preparation for replacement with an implant. Read more
Porcelain Laminate Veneer on a Highly Discoloured Tooth: A Case Report
The biomimetic characteristics of porcelain veneers make them useful for managing esthetic problems and minimizing dental tissue reduction. This detailed description illustrates these advantages in the restoration of a single discoloured tooth. Read more
Our Global Connection
CDA’s ongoing involvement with the FDI World Dental Federation culminates each year with participation at the FDI Congress. This year’s event included discussions regarding a United Nations policy on the mining of mercury that could have an impact on the availability of dental amalgam worldwide. Read more
Magnet-Retained Implant-Supported Overdentures: Review and 1-Year Clinical Report
Prosthodontic magnets made from alloys of samarium and neodymium have advantages over older types of magnets. Preliminary evidence is offered for the excellent potential of these newer magnets for retention of mandibular implant-supported overdentures. Read more
Study Examines BPA in Dental Materials
An article published in Pediatrics assessing the benefits and potential health risks of dental materials that may contain bisphenol A (BPA) has generated extensive media coverage in the United States. Read more
Factors Affecting the Energy Delivered to Simulated Class I and Class V Preparations
The energy delivered by a light curing unit in a simulated clinical environment was affected by the operator’s technique, the choice of light curing unit and the location of the tooth preparation. Read more
Light Energy Matters
The energy delivered by a light curing unit is key to the success of a resin restoration. Four variables determine how long a curing light should be used to adequately cure a resin: curing light design and condition; technique used by the operator; type and location of the restoration; and the energy requirements of the resin used. Read more
Comparative Translucency of Esthetic Composite Resin Restorative Materials
The translucency of 39 composites representing various shade-and-translucency combinations was measured. In general, “opaque” and “dentin” composites had low translucency, “universal” or “body” composites had intermediate translucency, and “enamel” composites had high translucency. Read more
