Is the anatomy of the root canal system a challenge to effective disinfection?

This summary is based on information found in Disinfection of Root Canal Systems: The Treatment of Apical Periodontitis (Wiley Publishing, 2014)   Six biological factors that lead to asymptomatic radiolucencies persisting after root canal treatment: Intraradicular infection persisting in the complex apical root canal system; Extraradicular infection, generally in the form of apical actinomycosis; Extruded root canal filling or other exogenous materials that cause a foreign body reaction; Accumulation of endogenous cholesterol crystals that irritate apical tissues; and True cystic lesions, and (vi) scar tissue (1). The internal anatomy can be notoriously complex, especially in molars, and includes extra canals, recesses, fins, isthmuses, and accessory canals that provide space for the biofilms ...

What are some of the implant complications associated with systemic disorders and medications?

This summary is based on information found in Dental Implant Complications: Etiology, Prevention, and Treatment, 2 (Wiley Publishing, 2015) Key messages Patient selection is the critical factor for implant success and survival in any medically complex situation. When medical conditions are managed wisely, most patients have improved overall health with fixed replacements as opposed to removable appliances. Exceptional care must be taken so that any implants placed will be successful and safe for the clinician and the patient. It is essential to routinely review the literature and expect that protocols for patients with systemic diseases or taking medications will be regularly updated as our knowledge of dental implants advances.   Although ...

Implant Complications: What is the Scope of the Problem?

This summary is based on information found in Dental Implant Complications: Etiology, Prevention, and Treatment, 2nd Edition (Wiley Publishing, 2015) The introduction of endosseous dental implants as an option for restoring partially and fully edentulous patients has revolutionized dental treatment. High survival rates reported for single and multiple missing tooth replacements have validated the use of implant-supported restorations as a predictable method for oral rehabilitation (1–9). Problems with implant complications have grown in number and complexity and that is reflected in the increased number of articles, journals, and continuing education conferences that have recently been devoted to the topic of implant complications (12–31). Reasons for the increased numbers of implant complications The ...

Distinct Oral Neutrophil Subsets Define Health and Periodontal Disease States

Dr. Michael Glogauer, from the Faculty of Dentistry at the University of Toronto, recently published an article in the Journal of Dental Research titled: Distinct Oral Neutrophil Subsets Define Health and Periodontal Disease States. In this interview Dr. Glaogauer gives further details about this research and its significance for dentistry.  Highlights Neutrophils exit the vasculature and swarm to sites of inflammation and infection. However, these cells are abundant in the healthy, inflammation-free human oral environment, suggesting a unique immune surveillance role within the periodontium. We hypothesize that neutrophils in the healthy oral cavity occur in an intermediary parainflammatory state that allows them to interact ...

Patterns of Antibiotic Prescription in Implant Surgery in Sweden

Drs. Bodil Lund and Dalia Khalil spoke with Dr. Suham Alexander about their latest research into the patterns of antibiotioc prescription in Sweden. Highlights Antibiotic prophylaxis is often required to prevent bacterial infection pre- or post-procedure. Controversy exists regarding the benefits of prescribing antibiotics for routine implant placement surgery. The risks associated with improper or overuse of antibiotics is well-documented – emergence of resistant strains, side-effects, drug interactions and allergies. This investigation studied the prescription patterns of Swedish dentists before and after the publication of recommendations on dental implant procedures and antibiotic use (2008 and 2012, respectively). The study results ...
