https://www.readbyqxmd.com/read/28727999/drug-ion-co-delivery-multi-functional-nanocarrier-to-regenerate-infected-tissue-defect
#1
Jung-Hwan Lee, Ahmed El-Fiqi, Nandin Mandakhbayar, Hae-Hyoung Lee, Hae-Won Kim
Regeneration of infected tissues is a globally challenging issue in medicine and dentistry. Common clinical therapies involving a complete removal of infected areas together with a treatment of antimicrobial drugs are often suboptimal. Biomaterials with anti-bacterial and pro-regenerative potential can offer a solution to this. Here we design a novel nanocarrier based on a mesoporous silicate-calcium glass by doping with Ag ions and simultaneously loading antimicrobial drugs onto mesopores. The nanocarriers could controllably release multiple ions (silver, calcium, and silicate) and drugs (tetracycline or chlorohexidine) to levels therapeutically relevant, and effectively internalize to human dental stem cells (∼90%) with excellent viability, ultimately stimulating odontogenic differentiation...

REVIEW
Kelvin I Afrashtehfar, Mansour K Assery
It has been claimed that in order to decrease the gap between what we know and what we do, research findings must be translated from knowledge to action. Such practices better enable dentists to make evidence-based decisions instead of personal ideas and judgments. To this end, this literature review aims to revisit the concepts of knowledge translation and evidence-based dentistry (EBD) and depict their role and influence within dental education. It addresses some possible strategies to facilitate knowledge translation (KT), encourage dental students to use EBD principles, and to encourage dental educators to create an environment in which students become self-directed learners...

Although the risk of injuring the lingual nerve in the mandibular molar area during dental treatment is high, it can be repaired by nerve grafting. However, from the perspective of clinical dentistry, the pathway and histomorphometric characteristics of this nerve remain to be documented in detail. The purpose of the present study was to morphologically elucidate the pathway of the lingual nerve to clarify its significance in a clinical setting. A histomorphometric analysis was also performed in consideration of nerve grafting...

T M H de Jong, M L Laine
Halitosis or bad breath is a problem that affects many people and its source is generally found in the oral cavity (intra-oral halitosis). Bacteria in the oral cavity produce volatile sulphur compounds such as hydrogen sulphide and methyl mercaptan that not only emit an unpleasant odour, but may also have toxic effects on the periodontal tissues. Good oral hygiene, a healthy periodontium and healthy teeth are the basis for the prevention of intra-oral halitosis and dentists and dental hygienists therefore play an essential role in its prevention...

Yogendra Imran, Muhammad Raza, Muhammad Sartaj Khan, Yousaf Hayat
BACKGROUND: Re-use of dental casting alloy is a routine practice, which is carried out with the motive to conserve resources. There have been studies on the re-use of alloys but a controversy exists as to the proportioning ratio of fresh to used alloy and the number of time an alloy can be recast. The objective of the study was to measure the effect of addition of 50% by weight used alloy to the fresh Cobalt-Chromium alloy on the castability. METHODS: In the present in-vitro experimental study A total of 20 specimens were cast by flame centrifuge, using modified Whitlock's method...

Bernard J Moxham, Diogo Pais
Medical and dental curricula, together with anatomical sciences courses, are increasingly having to change, mainly because there is a drive to being what is termed, without adequate definition, 'clinically relevant'. The concept of 'clinical anatomy' has accordingly been invented and it is expected that, at all times, the teaching of anatomy is directly focussed on clinical scenarios, meaning almost invariably the 'disease-based model of medicine and dentistry'. Furthermore, students are not expected to have a detailed knowledge of gross anatomy and the time devoted to teaching and learning the subject has decreased significantly...

OBJECTIVES: Dental resin-based materials are widely used in modern dentistry. Especially, resin cements enjoy great popularity and are utilized in many applications. Nevertheless, monomers could be released from the resinous matrix, thus interact with surrounding tissues, cause adverse biological reactions and may lead in cases of implant retained restorations to peri-implant bone destruction. Hence, we performed an in-vitro study to determine cytotoxicity of resin monomers on osteoblast-like cells...
