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 ...

Could green tea improve bond strength following bleaching?

  This summary is based on the article published in the European Journal of Oral Sciences: Can green tea be used to reverse compromised bond strength after bleaching? (August 2013)       Purpose of the Study  Evaluate the antioxidant effect of green tea on microtensile bond strength to bleached enamel. Key Messages Green tea catechins have been shown to possess potent antioxidant activity several times higher than that of vitamin C and vitamin E. The strong antioxidant properties of green tea have been attributed to catechins of EGCG and EGC which can donate hydrogens from the hydroxyl groups in their structure and have ...

Does gender matter in patient-provider interactions?

This summary is based on the article published in the Dental Clinics of North America: Interactions between patients and dental care providers. Does gender matter? (April 2013) Key Messages Gender differences exist both in verbal and nonverbal communication.
