Are gingival cells a therapeutic solution?

This summary is based on the article published in the Stem Cell and Development journal: Gingiva as a source of stem cells with therapeutic potential (December 2013)  Benjamin P.J. Fournier, Hannu Larjava, and Lari Hakkinen Context Postnatal connective tissues contain phenotypically heterogeneous cells populations that include distinct fibroblast subpopulations, pericytes, myofibroblasts, fibrocytes, and tissue-specific mesenchymal stem cells (MSCs). These cells play key roles in tissue development, maintenance, and repair and contribute to various pathologies. Depending on the origin of tissue, connective tissue cells, including MSCs, have different phenotypes. Understanding the identity and specific functions of these distinct tissue-specific cell populations may allow researchers to develop ...

How safe is oral midazolam sedation in pediatric dentistry?

This summary is based on the article published in the International Journal of Pediatric Dentistry: Safety of oral midazolam sedation use in pediatric dentistry: a review (January 2014) Context Young children needing multiple procedures often cannot be managed using local anesthesia alone. General anesthesia (GA) is an alternative, but is associated with significant morbidity and expense.  Sedation is a possible alternative to GA for behaviour management but evidence in support of its use is weak. A recent systematic review noted that oral midazolam is one of the few agents available whose efficacy in dental procedures for children is supported by evidence. Midazolam is potentially an ideal sedative agent for pediatric dentistry because ...
