Diagnosing periodontal disease: what is the periodontal classification system?

This question was submitted by a general dentist: What are the latest thoughts on periodontal disease and the classification used for its diagnosis? Dr. Sayed Mirbod, representing the Canadian Academy of Periodontology (CAP), provided this initial quick response The benefit of a classification system is to provide a framework to study the etiology, progression and treatment for a disease. The system can also be used by clinicians to organize their patients’ health-care needs. Diagnosing periodontal disease is directly related to the classification system that is used by the clinician and the variations in the definition of periodontal health, gingivitis and periodontitis ...

Posterior Partial Coverage Restorations: how fracture resistant and what is the risk of failure?

This summary is based on the article published in the Journal of Esthetic and Restorative Dentistry: Evaluation of fracture resistance and failure risks of posterior partial coverage restorations (April 2013) Context The interest in posterior partial coverage restorations has increased because these restorations provide a more conservative treatment option than traditional cohesively based restorations; however, material selection has been a controversial topic in the current literature. Purpose of the Study To evaluate the fracture resistance of posterior partial coverage restorations restored with different materials, examine their stress distribution, and calculate failure risks using three-dimensional (3D) finite element analysis. Key Messages Fracture resistance and ...

How to preserve coronal tooth fragments prior to reattachment?

This summary is based on the article published in the Australian Dental Journal: Preservation of coronal tooth fragments prior to reattachment (September 2013) Shirani F, Sakhaei Manesh V, Malekipour M. Preservation of coronal tooth fragments prior to reattachment. Aust Dent J. 2013 Sep;58(3):321-5. Context Crown fractures are the most common form of dental injuries caused by trauma. If the fragment is retrieved after the trauma, reattachment could be a viable treatment option. Reattachment of the tooth fragment is a well accepted treatment option in dealing with crown fractures. Hydration of the fragment is an important aspect in this treatment. Purpose of the Study The ...

What is the clinical evidence on approaches to caries removal?

This summary is based on the Critical Appraisal published in the Journal of Esthetic and Restorative Dentistry: Approaches to caries removal: what the clinical evidence says (April 2013) Context  It is very common that complete caries removal in vital, asymptomatic teeth with deep carious lesions ends in unavoidable exposure of the pulp. As a result, the complexity and cost of treatment increases dramatically and many patients are left with extraction as their only viable option.The review appraises evidence which supports alternative treatments designed to preserve the vitality of the tooth and thus avoid extraction. Studies Reviewed Evaluation of Atraumatic Restorative Treatment and Sealants under ...

Is the epidemiological scoring system for tooth erosion/wear useful?

This summary is based on the article published in the International Dental Journal: An epidemiological scoring system for tooth wear and dental erosive wear (June 2013) Context The prevalence and severity of tooth wear and dental erosion is rising in children and there is no consensus about an index to be employed.  Purpose of the Study The study aims to assess the reliability of an epidemiological scoring system dental wear index (DWI) to measure tooth wear and dental erosive wear.  Key Messages Tooth wear increases with age and males experience it more than females in primary teeth. No significant gender difference of ...

Is there a relationship between GERD and dental erosion?

This summary is based on the Critical Appraisal published in the Journal of Esthetic and Restorative Dentistry: Dental Erosion (June 2013) Context Dental erosion or erosive tooth wear not only can be caused by extrinsic (dietary) acids but also intrinsic acids. Historically, anorexic and bulimic patients have been the population dentists have had to be aware of, but with the increasing prevalence of gastroesophageal reflux disease (GERD) in the general population, another population must be monitored. Tooth wear is usually multifactorial, and it is often difficult to assign a specific etiology; abrasion, attrition, and erosion must all be considered as potential etiologies. This critical ...

How effective are antibiotics in the treatment of peri-implantitis?

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 ...
