Endodontics (from the Greek endo "inside"; and odons "tooth") is one of the dental specialties recognized by the American Dental Association, Royal College of Dentists of Canada, and Royal Australasian College of Dental Surgeons, and deals with the tooth pulp and the tissues surrounding the root of a tooth. Endodontists perform a variety of procedures including root canal therapy, endodontic retreatment, surgery, treating cracked teeth, and treating dental trauma. Root canal therapy is one of the most common procedures. If the pulp (containing nerves, arterioles, venules, lymphatic tissue, and fibrous tissue) becomes diseased or injured, endodontic treatment is required to save the tooth.

Training

Australia

Australian programs are accredited by the Australian Dental Council (ADC) and are 3 years in length and culminate with either a Master degree (MDS) or a Doctor of Clinical Dentistry degree (DClinDent). Fellowship can then be obtained with the Royal Australasian College of Dental Surgeons, FRACDS (Endo).

Canada

Canadian programs are accredited by the (CDAC) and are a minimum of two years in length to a maximum of 8 years in length and usually culminate with a master (MSc or MDent) degree. Graduates are then eligible to sit for the Fellowship exams with the Royal College of Dentists of Canada (FRCD (C)).

USA

In the United States after a dentist finishes his or her dental degree the dentist must undergo 2-3 additional years of postgraduate training to become an endodontist. The American Dental Association (CODA) accredited programs are a minimum of two years in length. Following successful completion of this training the dentist becomes Board eligible to sit the American Board of Endodontology examination. Successful completion of board certification results in Diplomate status in the American Board of Endodontology.

There are 50 endodontic training programs in the United States, in which roughly 400 students are enrolled. ^[1]

India

In India after a dentist finishes his or her Bachelor in Dental Surgery Programme, he or she must undergo 3 additional years of postgraduate training (Master in Dental Surgery) to become an endodontist.

Preparation, characterization, and antibacterial activity studies of silver-loaded poly(styrene-co-acrylic acid) nanocomposites.

Electronic address: lzdai@xmu.edu.cn.AbstractA simple method for preparing a new type of stable antibacterial agent was presented. Monodisperse poly(styrene-co-acrylic acid) (PSA) nanospheres, serving as matrices, were synthesized via soap-free emulsion polymerization. Field-emission scanning electron microscopy micrographs indicated that PSA nanospheres have interesting surface microstructures and well-controlled particle size distributions. Silver-loaded poly(styrene-co-acrylic acid) (PSA/Ag-NPs) nanocomposites were prepared in situ through interfacial reduction of silver nitrate with sodium borohydride, and further characterized by transmission electron microscopy and X-ray diffraction. Their effects on antibacterial activity including inhibition zone, minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), and bactericidal kinetics were evaluated. In the tests, PSA/Ag-NPs nanocomposites showed excellent antibacterial activity against both gram-positive Staphylococcus aureus and gram-negative Escherichia coli. These nanocomposites are considered to have potential application in antibacterial coatings on biomedical devices to reduce nosocomial infection rates.

Electronic address: yangf82@sina.com.AbstractOBJECTIVE: A growing body of evidence has implicated human oral microbiota in the aetiology of oral and systemic diseases. Nasopharyngeal carcinoma (NPC), an epithelial-originated malignancy, has a complex aetiology not yet fully understood. Chemoradiation therapy of NPC can affect oral microbiota and is usually accompanied by plaque accumulation. Thus, the study aimed to understand the diversity, divergence and development of the oral microbiota in NPC patients and their associated treatment, which might provide useful insights into disease aetiology and treatment side effects.

Electronic address: dr.hassan@gmx.de.AbstractThe presence and the involvement of cancer stem-like cells (CSCs) in tumor initiation and progression, and chemo-resistance are documented. Herein, we functionally analyzed melanoma stem-like cells (MSC)/CD133(+) cells on their resistance and response to taxol-induced apoptosis. Besides being taxol resistant, the CD133(+) cells demonstrated a growth advantage over the CD133(-) subpopulation. Taxol induced apoptosis on CD133(-) cells, but not on CD133(+) cells. In the CD133(-) subpopulation, the exposure to taxol induced the activation of apoptosis signal-regulating kinase1 (ASK1)/c-jun-N-terminal kinase (JNK), p38, extracellular signal regulated kinase (ERK) pathways and Bax expression, while in CD133(+) cells taxol was able only to enhance the activity of the ERK pathway. In CD133(+) cells, the direct gene transfer of Bax overcame the acquired resistance to taxol. Taken together, our data provide an insight into the mechanistic cascade of melanoma resistance to taxol and suggest Bax gene transfer as a complementary approach to chemotherapy.
