This study evaluates the effect on post space debridement in oval-shaped canals of an experimental ultrasonic tip with oval section (Satelec) compared with a circular ultrasonic tip (KaVo). Thirty teeth with an oval-shaped canal were endodontically treated and obturated and then randomly divided into 3 groups (n = 10) according to the procedure used for post space debridement: Satelec tip, Largo #2 drill + KaVo file, and Largo #2 drill + water. Debris and dentin tubules were evaluated by assigning scores to scanning electron microscope post spaces images; lower scores corresponded to fewer debris and higher number of open tubules. The Satelec group showed significantly lower debris and open tubules scores than KaVo group (p < .05) and control group (p < .05), which differed significantly between each other (p < .05). Also the debris and open tubules scores in different post space regions differed significantly among the experimental groups (p < .001). The oval ultrasonic tip resulted in a better post space debridement than a circular ultrasonic tip in oval-shaped canals.

Tarsal tunnel syndrome is an entrapment neuropathy of the tibial nerve and its branches in the tarsal tunnel. The literature on surgical release of the tarsal tunnel shows variable outcomes with no studies reporting validated patient reported outcomes. We aim to determine clinical response after tarsal tunnel release using the Patient-Reported Outcomes Measurement Information System (PROMIS).

Nickel complexes are a potential candidate for antibacterial and antifungal activity. A new Ni (II) complex, bis(2-methoxy-6-{[(2-methylpropyl)imino]methyl}phenolato)nickel (II) (2), was synthesised by reacting, bis(3-methoxy-salicylaldehyde)nickel (II) (1) with isobutylamine. It was characterised by single crystal X-ray diffraction (ScXRD), UV-Vis, NMR, IR, mass spectrometry, and thermogravimetry (TG) to study its structure and physico-chemical properties.

The retrospective study aimed to compare the space-maintaining effects of sticky bone (bone graft matrix enriched with injectable platelet-rich fibrin) and titanium mesh for bone augmentation in the aesthetic zone. Patients who underwent single implant placement and had type 2/4 alveolar bone defects (buccal bone wall loss is >50% of the expected implant length) were screened for inclusion in this study. The labial bone plate width was measured at 1, 3, and 5 mm below the apical implant platform on cone beam computed tomography images taken immediately and 6 months after surgery.

Context: Limited information exists regarding the immediate and short-term effects of scapula retraction exercises (SREs) on acromiohumeral distance (AHD) in subacromial pain syndrome (SPS). This study's 2 main objectives were to investigate (1) the immediate effect of the SRE on AHD at varying shoulder abduction angles in patients with SPS and healthy controls and (2) the effect of the 8-week SRE program on AHD in patients with SPS.
Design: Cross-sectional and pre-post intervention designs were utilized on this study.
