Background: The occurrence of secondary caries is the most common reason for the restorations failures.
Aim: The aim of the study was to evaluate and compare the anticaries effect of copper ions on the teeth restored with glass ionomer cement (GIC) and composite restorations in the cavity prepared by galvanic and sintered burs.
Materials And Methods: A total of 40 premolars were divided into two halves buccolingually. Class V cavity was prepared with sintered diamond burs and galvanic diamond bur. Cavities were restored with either GIC or composite resin. The monospecies artificial microbial caries model was selected for induction of secondary caries. The lesions were measured at junction of restoration by confocal laser scanning microscope.
Results: The results were statistically significant ( < 0.001) and suggested that the width of lesion was lowest in cavity prepared by sintered bur and restored with composite resin.
Conclusion: The use of different burs in combination with various restorative materials influence the occurrence and width of caries lesion.

Introduction: Human amniotic membrane (hAM) has a highly biocompatible natural scaffold that is abundant in several extracellular matrix (ECM) components, including but not limited to platelet-derived growth factor (PDGF), transforming growth factor (TGF), and fibroblast growth factor (FGF). In our study, we have focused on a mixture of hAM and demineralized bone matrix (DBM) as an allo-hybrid graft to deliver it into the site of bone defect to decrease bone remodeling time.
Methods: Allo-hybrid grafts were prepared by coating the jelly made of decellularized and lyophilized hAM (AMJ) on the surface of DBM and subsequently underwent in vitro studies, such as alkaline phosphatase activity, MTT assay, and SEM analysis.

Methodology: One hundred mandibular premolars inoculated with Enterococcus faecalis were divided into two groups: the control group (CG: n = 10), which received no treatment; and the test groups (n = 30), which included saline (SS), sodium hypochlorite (2.5% NaOCl) and chlorhexidine (2% CHX).
Spatio-temporal segregation between sensory relay and swallowing pre-motor population activities by optical imaging in the rat nucleus of the solitary tract.

The nucleus tractus solitarius (NTS) contains neurons that relay sensory swallowing commands information from the oropharyngeal cavity and swallowing premotor neurons of the dorsal swallowing group (DSG). However, the spatio-temporal dynamics of the interplay between the sensory relay and the DSG is not well understood. Here, we employed fluorescence imaging after microinjection of the calcium indicator into the NTS in an arterially perfused brainstem preparation of rat (n = 8) to investigate neuronal population activity in the NTS in response to superior laryngeal nerve (SLN) stimulation.

Aiming toward a novel, noninvasive technique, with a real-time potential application in the monitoring of the complexation of steroidal neuromuscular blocker drugs Vecuronium () and Rocuronium () with sugammadex (, medication for the reversal of neuromuscular blockade induced by or in general anesthesia), we developed proof-of-principle methodology based on surface-enhanced Raman spectroscopy (SERS). Silver nanoparticles prepared by the reduction of silver ions with hydroxylamine hydrochloride were used as SERS-active substrates, additionally aggregated with calcium nitrate as needed. The and SERS spectra were obtained within the biorelevant 5 × 10-1 × 10 M range, as well as the SERS of , though the latter was observed only in the presence of the aggregating agent.
