Orthodontic Alloy Wires and Their Hypoallergenic Alternatives: Metal Ions Release in pH 6.6 and pH 5.5 Artificial Saliva.

Legislative framework addresses the issues of alloy corrosion, demanding the restricted use of probable carcinogenic, mutagenic, and toxic-for-human-reproduction (CMG) metals like nickel, cobalt, and chromium and demanding the development of new biomaterials. The aim of this research was to evaluate and compare the ion release of standard dental alloys and their hypoallergenic equivalents. Six types of orthodontic alloy wires (nickel-titanium (NiTi), coated NiTi, stainless steel (SS), Ni-free SS, and cobalt-chromium (CoCr) and titanium-molybdenum (TMA) were immersed into artificial saliva of pH 5.

Antimicrobial Activity of Olive Leaf Extract to Oral Isolates.

Objectives: The aim of this study was to determine the antifungal activity of olive leaf extract (OLE) and the synergistic effect of standard antifungal therapy and OLE against clinical oral species' isolates.

Materials And Method: The susceptibility of 60 clinical isolates of the species (36 , 16 , 5 and 3 ) was tested with four concentrations of OLE (60 µg/µL, 120 µg/µL, 240 µg/µL and 333 µg/µL) and the synergistic effect of standard antifungal therapy and OLE (miconazole (MIC) + 333 µg/µL OLE and nystatin (NYS) + 333 µg/µL OLE). The antimicrobial activity was tested using the disk diffusion method.

PY Receptors Mediate Masseter Muscle Mechanical Hypersensitivity in Rats.

Purpose: PY receptors (PYRs) are among the various receptors that play an important role in nociception. The goal of this research was to investigate possible PYR expression changes in the trigeminal ganglion (TRG) in bilateral masseter muscle (MM) hypersensitivity following unilateral MM inflammation. The impact of unilateral intramasseteric administration of PYR antagonist on bilateral MM hypersensitivity was also explored.

Self Assessment of Dental students' Perception of Learning Environment in Croatia, India and Nepal.

Aim: The aim of this study was to assess dental students' perception of different learning environment in India, Nepal and Croatia.

Methods: The study was conducted during a period of academic year 2016/17. A total of 849 dental students participated in the study.

The role of P2X3 receptors in bilateral masseter muscle allodynia in rats.

Aim: To determine the relationship between bilateral allodynia induced by masseter inflammation and P2X3 receptor expression changes in trigeminal ganglia (TRG) and the influence of intramasseteric P2X3 antagonist administration on bilateral masseter allodynia.

Methods: To induce bilateral allodynia, rats received a unilateral injection of complete Freund's adjuvant (CFA) into the masseter muscle. Bilateral head withdrawal threshold (HWT) was measured 4 days later.
