Are there metabolic changes of dental pulp after rapid palatal expansion (RPE)?

This summary is based on the article published in the journal of Orthodontics and Cranofacial Research: Metabolic changes of human dental pulp after rapid palatal expansion (August 2013) F. L. Wei; J. Geng; J. Guo; Q. Y. Guo; H. Wang; D. X. Liu; B. J. Zhang; C. L. Wang. Metabolic changes of human dental pulp after rapid palatal expansion. Orthod Craniofac Res. 2013 Aug;16(3):185-92.  Context Rapid Palatal Expansion is (RPE) is an orthopedic technique frequently used to correct maxillary constriction and posterior cross-bite. High forces are produced during active expansion of the mid-palatal suture by RPE. Recently, the response of dental pulp tissue to orthodontic treatment ...

Is there evidence for the periodontal-systemic association?

In a Special Issue (April 2013), the Journal of Clinical Periodontology presented a series of articles that explored the association between periodontitis and some systemic diseases. The following is a summary of the article: Periodontal systemic association: review of the evidence Context The review aims to critically appraise recent research on the associations between periodontal disease and systemic diseases and conditions, specifically respiratory disease, chronic kidney disease, rheumatoid arthritis, cognitive impairment, obesity, metabolic syndrome, and cancer. Key Messages There was substantial heterogeneity in the definitions used to identify periodontitis and very few studies met a stringent threshold for periodontitis. There is a need ...

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 ...

Does local simvastatin-alendronate conjugate prevent periodontitis bone loss?

This summary is based on the article published in the Journal of Periodontal Research: Effects of local simvastatin-alendronate conjugate in preventing periodontitis bone loss (October 2013) Context Local host-modulation therapy is an emerging approach to prevent disease progression in sites with moderate periodontitis. The combination of simvastatin and alendronate would be an intriguing host-modulatory strategy because of the bone-anabolic properties of simvastatin and the antiresorptive/bone-targeting characteristics of alendronate. Purpose of the Study The objective of this study is to evaluate the effects of local administration of a simvastatin–alendronate–β-cyclodextrin (SIM–ALN–CD) conjugate for preventing experimental periodontitis bone loss. Key Message Locally applied SIM–ALN–CD ...

Is there an association between periodontitis and systemic diseases?

In a Special Issue (April 2013), the Journal of Clinical Periodontology presented a series of articles that explored the association between periodontitis and some systemic diseases. The following is a summary of the introductory article: Infections and inflammatory mechanisms Context The article examines the potential mechanisms that may play a role in the associations between periodontitis and some systemic conditions. Three basic mechanisms have been postulated to play a role in these interactions; metastatic infections, inflammation and inflammatory injury, and adaptive immunity. The potential role of each alone and together is considered in in vitro and animal studies and in human studies when available. The article is ...

Is there an association between periodontitis and obstructive sleep apnea?

This summary is based on the article published in the Journal of Periodontal Research: The association between periodontitis and obstructive sleep apnea: a preliminary study (August 2013) Context Periodontitis is becoming a highly prevalent disease worldwide. Obstructive sleep apnea is a common disorder that is characterized by repeated disruptions in breathing during sleep, and mouth breathing is a common characteristic among patients with obstructive sleep apnea. Purpose The study aimed to assess the hypothesis that obstructive sleep apnea is associated with the onset and progression of periodontal disease. Key Messages The study identified that there is a significant association between obstructive sleep apnea and periodontitis. ...

Are there underlying psychological factors for tooth wear?

This summary is based on the article published in Special Care in Dentistry: The psychology of tooth wear (January/February 2013) Context Tooth wear, also referred to as tooth surface loss (TSL) or non-carious TSL, has been defined as the “pathological loss of tooth tissue by a disease process other than dental caries”. The etiological factors of tooth wear include attrition, erosion and/or abrasion. Purpose of the Study Review the main psychological and mental conditions that are manifested dentally in the form of tooth wear. These conditions include depression, eating disorders, and alcohol and drug use disorders. Review the comorbidity of ...
