Evidence-based prosthodontics: what are the fundamental considerations, limitations, and guidelines?
This summary is based on the article published in the Dental Clinics of North America: Evidence-Based Prosthodontics: Fundamental Considerations, Limitations, and Guidelines (January 2014) Key Messages Prosthodontics is a unique specialty that offers numerous advantages and disadvantages for application of principles of evidence-based dentistry (EBD). An important difference between medical and dental models of care is the level of control a patient has about how, when, and whether it is necessary to treat a dental problem. This is especially true in the discipline of prosthodontics. Hence, an absolute extrapolation of evidence-based concepts from medicine to prosthodontics is not possible. Current lack of “strong” evidence for a particular ...Read More »
This case is presented by Dr. Emad Girgis I have a 66-year old patient, male Caucasian. Although on medications, these are not contributing to any health complications. The patient had a bridge, done on combined mini implants and teeth, tooth #42had been extracted prior to this X ray due to root fracture . #34 was extracted from under the bridge due to fracture as well. The bridge has been there for about 3 years and the gingiva seems to be healthy around the implants; so, I am assuming there is good integration. #33 has a large periapical radiolucency due to poor RCT ...Read More »
This summary is based on the article published in the International Dental Journal: Clinical efficacy of antibiotics in the treatment of peri-implantitis (August 2013) Context Various treatment regimes for Peri-implantitis (PI) have been proposed in the literature. As it is known that bacteria can transfer from periodontally involved teeth to an implant, and that the microbes associated with PI resemble those of periodontal disease, local or systemic delivery of antibiotics with traditional PI treatment regimes may eliminate periodontopathogenic bacteria to a greater extent compared with when these treatment regimes are performed alone. This in turn may facilitate healing of PI ...Read More »
What are the clinical considerations for dental implant therapy in irradiated head and neck cancer patients?
This summary is based on the article published in the Journal of Prosthodontics: Updated Clinical Considerations for Dental Implant Therapy in Irradiated Head and Neck Cancer Patients (August 2013) Context An increasing number of reports indicate successful use of dental implants (DI) during oral rehabilitation for head and neck cancer patients undergoing tumor surgery and radiation therapy. Implant-supported dentures are a viable option when patients cannot use conventional dentures due to adverse effects of radiation therapy, including oral dryness or fragile mucosa, in addition to compromised anatomy. However, negative effects of radiation, including osteoradionecrosis, are well documented in the literature, and early loss of implants in irradiated ...Read More »
This summary is based on the article published in Gerodontology: Clinical aspects of the use of dental adhesive materials in patients with chronic xerostomia (June 2013) Context Adhesives are commonly used by denture wearers to increase the retention and stability of the complete denture, to improve the chewing and masticatory abilities and to psychologically support the patient to make the complete denture more acceptable. Denture fixatives can be especially recommended for use and to aid retention for patients with dryness of the mouth, poor secretion of saliva and xerostomia (e.g. diabetes mellitus). Key Messages Adequately maintaining prostheses is influenced by a number of ...Read More »

This Urgent care Scenario (USC) is presented by the JCDA Oasis Team in collaboration with Dr. Samer Nuwwareh. The USC is also available through the Oasis Help system Food impaction is the forceful wedging of food into the periodontium by occlusal forces. It may occur as a consequence of gingival tissue recession or disease, caries, severe attrition, plunger cusp, or inappropriate interproximal contact and clearance.
