Radicular Dentin Thickness and Root Canal Morphology of Mandibular Incisors in Indian Subpopulation Using Cone Beam Computed Tomography.

Aim Using two classifications, this study assessed root morphology and canal configuration and measured the Dentin thickness (DT) and canal shapes. Methods Cone beam computed tomography (CBCT) with 400 Mandibular Incisors was collected and assessed for the number, length, curvature of roots, number of canals, bifurcation level, configurations based on Vertucci's and Ahmed's classification, DT and canal shape at 3, 6, 9 mm from the apex. The collected data was subjected to statistical analysis with a level of significance at p<0.

Insights Into the Effects and Implications of Acidic Beverages on Resin Composite Materials in Dental Restorations: An In Vitro Study.

Background: Dental composite resins are commonly used due to their excellent physical and mechanical properties. However, exposure to beverages like Coca-Cola, Apple juice, and Black coffee can negatively impact these materials. This study examined the effects of these drinks on the surface microhardness and surface roughness of Nanohybrid, Giomer, and Dual-Cure Bulk-fill resin composites.

Evaluation of the Role of Myofibroblast and Fibronectin in the Aetiopathogenesis of Cholesteatoma.

Background: Primary acquired Cholesteatoma is a complex issue for otolaryngologists, with its development mechanisms still unclear due to the intricate anatomy of this region. It's aetiopathogenesis remains poorly understood and this aggressive clinical condition often leads to various complications. Recent research explores myofibroblast and fibronectin's potential roles in pathomechanisms of Cholesteatoma.

Anomalous Superfluid Density in a Disordered Charge-Density-Wave Material: Pd-Intercalated ErTe_{3}.

We image local superfluid density in single crystals of Pd-intercalated ErTe_{3} below the superconducting critical temperature T_{c}, well below the onset temperature T_{CDW} of (disordered) charge-density-wave order. We find no detectable inhomogeneities on micron scales. We observe a rapid increase of the superfluid density below T_{c}, deviating from the behavior expected in a conventional Bardeen-Cooper-Schrieffer superconductor, and show that the temperature dependence is qualitatively consistent with a combination of quantum and thermal phase fluctuations.
