CARDP Meeting: Does Gold Still Hold A Place In Your Restorative Practice? Should It?

Dr. Randy Allan will be a speaker at the upcoming CARDP meeting which will take place in Halifax in September 2016. Highlights Dr. Randy Allan speaks to Dr. Suham Alexander about his presentation at the CARDP meeting and shares two of his many cases. Randy will be speaking about the use of gold as a restorative material. Gold has traditionally been a predictable and biocompatible restorative material in dentistry but, its use has declined over the years for several reasons: • Several tooth-coloured restorative materials are available • Patient perceptions about esthetics and how gold may show in the smile line ...

Exploring New Technologies: Eclipse Prosthetic Resin System

Anastasiya Sivkova, Denturist at Prosthodontic Associates, spoke with Dr. John O’Keefe about a new technology: the Eclipse Prosthetic Resin System. Highlights Eclipse, a denture based-resin composed of a composite and is similar to the white composite restorative materials. Acrylic is used prominently in dentures but some individuals have shown sensitivity to the monomers in acrylic denture materials. Eclipse is a fairly easy material to use and does not require the use of a blue light to set the material or the conventional processing as acrylic dentures. Once a final impression has been obtained, Eclipse can be used to build the ...

Rechargeable Anticandidal Denture Material with Sustained Release in Saliva

This summary is based on the article published in Oral Diseases: Rechargeable Anticandidal Denture Material with Sustained Release in Saliva (July 2016) A Malakhov, J Wen, B-X Zhang, H Wang, H Geng, X-D Chen, Y Sun, C-K Yeh Context Candida-induced denture stomatitis is a common debilitating problem among denture wearers. Previously, we described the fabrication of a new denture material that released antifungal drugs when immersed in phosphate buffered saline. Here, we use more clinically relevant immersion conditions (human saliva; 37°C) and measure miconazole release and bioactivity. Results HPLC was used to quantify miconazole levels in saliva. Miconazole-loaded disks released antifungal drug for up to 30 days. Higher drug ...

Rehabilitating Severely Worn Teeth: A Systematic Review

This summary is based on the article published in the Journal of Dentistry: Rehabilitation of severely worn teeth: A systematic review (May 2016) Mauro Elias Mesko; Rafael Sarkis-Onofre; Maximiliano Sérgio Cenci; Niek Johannes Opdam; Bas Loomans; Tatiana Pereira-Cenci Context Tooth wear is loss of dental hard tissue due to non-carious processes, and can be identified as attrition, abrasion, or erosion [1]. Irrespective of epidemiological concerns or even etiological factors, at an individual level, tooth wear may become severe requiring a restorative treatment to be considered, because severe tooth wear may result in loss of vertical dimension of occlusion, tooth sensitivity, decreased ...

Antibacterial monomers used in dental adhesive system: a systematic review

This summary is based on the article published in Dental Materials: A systematic review about antibacterial monomers used in dental adhesive systems: Current status and further prospects (November 2015) Alexandra Rubin Cocco; Wellington Luiz de Oliveira da Rosa; Adriana Fernandes da Silva; Rafael Guerra Lund, Evandro Piva Context There is a trend to use the minimally invasive dentistry approach to promote preservation of the tooth structure with conservative techniques in an effort to avoid damage to the dental pulp complex [1]. Incomplete removal of infected dentin is currently recommended, especially in clinical situations of deep carious lesions. However, viable bacteria that may ...

Review Article: Recent advances in bulk metallic glasses for biomedical applications

This summary is based on the article published in Acta Biomaterialia: “Recent advances in bulk metallic glasses for biomedical applications” (May 2016) H.F. Li, Y.F. Zheng, Department of Materials Science and Engineering, College of Engineering, Peking University Context With a continuously increasing aging population and the improvement of living standards, large demands of biomaterials are expected for a long time to come. Further development of novel biomaterials, that are much safer and of much higher quality, in terms of both biomedical and mechanical properties, are therefore of great interest for both the research scientists and clinical surgeons. Compared with the ...

What information do I need to communicate to my dental lab?

In order to optimize the final functional and esthetic result for patients, the dentist and dental laboratory must work as a team. As such, communication and common understanding is extremely important. Both parties must be able to interpret the other’s terminology effectively and accurately. Ideally and where possible, the dental and laboratory teams should meet and become familiar with one another. In the case where a practitioner uses a lab that is not local, electronic communication, such as email or Skype, may be used to convey critical information to the lab as long as appropriate patient consent is obtained. Prescriptions ...

What are THE key factors to consider when buying a new curing light?

In the following video conversation, a panel of experts, including Drs. Howard Strassler, Joe Oxman, and Fred Rueggeberg, spoke with Dr. John O’Keefe, Director of Knowledge Networks at CDA, about THE key factors to consider when buying a new curing light.    Panel Discussion Highlights All lights are not created equally and affect the quality of cure of composite restorations. Here’s what you need to know. Access and Ergonomics Light tips should access all aspects of the tooth’s surface easily and still emit light at right angles to the restoration’s surface. The light should also be easy to use in all patients (children and adults) ...
