What are the clinical outcomes of implant abutments in the anterior region?

This summary is based on the article published in the Journal of Esthetic and Restorative Dentistry: Clinical outcomes of implant abutments in the anterior region: a systematic review (June 2013) Context Current paradigms for treatment success in implant dentistry are based not only on true clinical outcomes, such as implant survival, restoration survival, and patient satisfaction but also on surrogate clinical outcomes such as dentogingival esthetics, rate of mechanical complications, bone levels, and health of surrounding soft tissues. This is especially important for implant therapy in maxillary and mandibular anterior regions, where esthetics play a predominant role in treatment success. Purpose of the Study The clinical outcomes of ...

Does stepwise excavation enhance pulp preservation?

This is a summary of the article published in the Journal of Dentistry: Ways of enhancing pulp preservation by stepwise excavation. A systemic review (February 2011) Context  The best possible methods and materials in stepwise excavation for deep caries in permanent teeth were investigated. Purpose The  review considers the questions from many aspects including clinical success, effects of reducing cariogenic bacteria, possibility of hardening softened dentin, and likelihood of generating tertiary dentin. Data This systematic review includes the use of data from randomized controlled trials, controlled clinical trials as well as from case series in which pulp exposure resulted following the treatment and ...

What is the continuum of behaviour guidance?

This is a summary of the article published in the Dental Clinics of North America: The continuum of behaviour guidance (January 2013) Context Most treatments provided within the comprehensive dental care of children are relatively simple, yet many practitioners find that delivering high-quality care to young children is challenging simply because they are performed on a child. The provision of dental care to children presents unique challenges and opportunities. To effectively treat children, providers must be prepared to address child behavior and leverage appropriate behavior guidance techniques. Key Messages Behavior guidance is a continuum of skills spanning from basic to ...

This question was submitted to us by a general dentist: How should we manage a patient undergoing an allogeneic bone marrow transplant? Dr. Jeff Chadwick, at Princess Margaret Cancer Centre, Dental Oncology, Ocular, and Maxillofacial Prosthetics Group, provided a preliminary response to this question The allogeneic bone marrow transplant (BMT) is a medical procedure that may be employed for the treatment of several hematologic malignancies including, but not limited to, aplastic anemia, myelodysplastic syndrome, acute and chronic leukemias and lymphomas. BMTs typically involve the insertion of a central venous catheter (CVC), high dose chemotherapy and, in some cases, total body irradiation, prior ...

What is an alveolar fracture?

This post is an adaptation of the Alveolar Fracture article found in the Dental Trauma Guide Description A fracture of the alveolar process; may or may not involve the alveolar socket. Teeth associated with alveolar fractures are characterized by mobility of the alveolar process; several teeth typically will move as a unit when mobility is checked. Occlusal interference is often present. Etiology Diagnosis A fracture of the alveolar process; may or may not involve the alveolar socket. Teeth associated with alveolar fractures are characterized by mobility of the alveolar process; several teeth typically will move as a unit when mobility ...

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 ...

Opening the Conversation: Is Dental Caries an Infectious Disease?

This question is a conversation opener on the nature of the caries process Dentists agree that demineralization of tooth surfaces from bacterial acid production is the direct cause of caries. However, the concept of dental caries as an infectious disease is less clear: dental caries are caused by bacteria that are resident flora in the oral cavity, not by an infection of a specific, foreign microorganism—the classical notion of an infectious disease. If the infection is caused by bacteria that originate from the host, can tooth decay be considered an infectious disease and why does it matter? Many dentists were ...
