CNTN2 Deficiency Disrupts Ascending Auditory Neuroglial Interactions and Redox Homeostasis in Neural Presbycusis

Advanced Science, EarlyView.
. ABSTRACT Neural presbycusis disrupts auditory timing and speech perception, yet its molecular basis remains poorly understood. This study identifies Cntn2 as the Ranvier's nodal molecule significantly downregulated in aged auditory nerves. Cntn2 heterozygous knockout (Cntn2+/−) mice showed elevated auditory brainstem response thresholds and prolonged

Comparative evaluation of depth of penetration of sealer after using EDTA, citric acid and R-EDTA as last irrigant under confocal laser microscopy

Endodontology
Aim: This original research examines potential of root canal sealers to penetrate the dentin. Movement of root canal sealer into dentinal tubules decreases the residual space for the entombing of bacteria and provides the hermetic seal.

Stereomicroscopic Dye Leakage Measurement of Six Different Root Canal Sealers [PDF]

Journal of Clinical and Diagnostic Research, 2017
Introduction: Hermetic sealing of the root canal is the most desirable outcome of any root canal treatment, but almost always the filling of the root canal is defective, which is a multifactorial outcome.

Evaluating the efficacy of Vibrospiral novel sealer placing instrument: a Confocal and Scanning Electron Microscope in-vitro study

BMC Oral Health
Background An endodontic sealer forms an interface between gutta-percha and root canal walls. Ideally, the sealer layer should be void-free, thin, uniform, well-adapted to the dentinal walls, and exhibit good tubular penetration, which contributes to a ...
