Effects of ınjectable platelet-rich fibrin in experimental periodontitis in rats
AbstractInjectable platelet-rich fibrin (i-PRF) is an effective biological material that positively contributes to angiogenesis, wound healing, inflammation, regeneration processes, etc. This research aimed to evaluate the effect of i-PRF in rats with experimental periodontitis. Following the development of ligature-induced periodontitis, 24 Wistar albino rats were divided into three groups. Group-1: scaling and root planing (only-SRP); Group-2: SRP  + i-PRF; Group-3: only- i-PRF. Heart blood from six donors was used for the i-PRF application. i-PRF was administered as a subgingival injection in the relevant ...

Usefulness of MR imaging for odontogenic tumors
AbstractMRI has become an invaluable diagnostic tool in all areas of the body. However, it has not been widely used to image odontogenic tumors of the jaw. Major advantages of MRI include excellent soft tissue contrast in the absence of ionizing radiation. Furthermore, diffusion-weighted MRI and dynamic contrast-enhanced MRI can be used as functional imaging techniques for assessing tissue biology. In this review article, we present representative MR images of several types of odontogenic tumors, and discuss MR imaging characteristics useful for differential diagnosis. (Source: Odontology)

Effect of epinephrine on the distribution of ropivacaine and lidocaine using radioactive isotopes in rat maxilla and pulp
AbstractWe compared the effect of epinephrine on the distribution of ropivacaine and lidocaine by using radioactive isotopes in rat maxilla and pulp. Twenty microliters of 3H-labeled 0.5% ropivacaine, 14C-labeled 2.0% lidocaine, or epinephrine-supplemented isotopes were injected into the maxilla. The radioactivity was measured and autoradiography was obtained. Epinephrine led to increase in amounts of both anesthetics in the maxilla and pulp; however, each anesthetic did so in a different manner. Addition of epinephrine to lidocaine decreased radioactivity in maxilla and pulp with time. Conversely, when ropivacaine with ep...

Pain sensitivity after low-level clenching is influenced by preloading eccentric exercise
ConclusionsEccentric exercise may facilitate pain sensitivity induced by subsequent low-level clenching via the central nervous system. In addition, it was demonstrated that pain sensitivity after the low-level clenching could be influenced by the type of preloading exercise. These experimental results may suggest that eccentric exercise could act as one of the triggering factors in the mechanism by which tooth clenching leads to a chronic pain condition in susceptible individuals.

Effect of vasopressin as a local anesthetic in mice
AbstractWe sought to elucidate how the local administration of mepivacaine hydrochloride and vasopressin via the tail affects the peripheral blood flow volume, tissue dynamics, and mepivacaine ’s anesthetic effect in mice. Two-hundred and twenty-six male ICR mice were used in this study. Blood flow was measured after administering mepivacaine alone or mepivacaine with either 0.03, 0.3, or 3.0 U/mL vasopressin or 10 µg/mL epinephrine via the tail tissue. The tail tissue and blood dynam ics were measured using3H-labeled mepivacaine hydrochloride with vasopressin or epinephrine. The compound nerve action pote...

Mallampati test with phonation, tongue protrusion and supine position is most correlated with Cormack –Lehane test
In this study, we studied the correlation between eight types of protocol (standard and seven alternati ve protocols) of Mallampati test and Cormack–Lehane test. We newly designed assessment protocols as new Mallampati test. These are different protocols depending on the presence or absence of phonation, those of protrusion of tongue, and sitting position or supine position. The oropharyngeal struct ures visualized by these eight types of Mallampati test for total of 145 patients undergoing dental oral surgery were evaluated. The scores derived via eight types of Mallampati test were recorded. The influence of phonat...
