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.

Advances in research on layered double hydroxides for biomedical applications

Smart Molecules, EarlyView.
Layered double hydroxides (LDHs) are pH‐responsive nanomaterials with broad biomedical applications. This review summarizes LDH synthesis methods and compares their advantages. It highlights LDHs' progress in cancer therapy, including chemo‐photothermal, chemo‐immunotherapy, and photodynamic‐immunotherapy combinations and their potential in bone repair.

Zinc Oxide-Eugenol Cements: IV. Microstructure and Hydrolysis

, 1973
The microstructure of zinc oxide-eugenol cement and the water-leached product was examined by electron microscopy and scanning electron microscopy. Crystalline zinc eugenolate, which forms a reaction product, encases and binds unconsumed zinc oxide ...

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

VIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Effects of Calcium Hydroxide Paste and Access Cavities on Fracture Strength of Mature and Simulated Immature Human Teeth: Ex Vivo

Australian Endodontic Journal, EarlyView.
ABSTRACT The aim was to examine whether a Ca(OH)2 paste affects fracture strength of teeth. Sixty extracted maxillary central incisors were prepared to simulate immature teeth. Another 40 were used as mature teeth. The ten groups (n = 10) were: (1) immature control; (2) immature + access; (3) immature + access + 1 m Ca(OH)2; (4) immature + access + 12 ...

Influence of Tapered‐End and Round‐End Bristle Designs on the Abrasive Enamel Wear Using Toothpastes With High Discrepancies in Abrasiveness

International Journal of Dental Hygiene, EarlyView.
ABSTRACT Purpose The aim of this in vitro study was to investigate the influence of bristle end design of toothbrushes and the relative enamel abrasivity (REA) of used toothpaste on the resulting abrasive enamel wear. Materials and Methods A total of 160 bovine enamel samples were allocated into eight groups (n = 20) and surface topography was recorded

Endodontic Treatment of Apical Periodontitis Mitigates Systemic Inflammation and Restores the Blood–Brain Barrier Integrity in an In Vitro Model

International Endodontic Journal, EarlyView.
ABSTRACT Aim A growing body of research supports an association between periapical inflammation and an increased risk of various systemic effects. However, there is currently no scientific evidence demonstrating a causal relationship between this inflammation and changes in epithelial or endothelial permeability in patients with apical periodontitis ...

Prevention and Management of Tooth Discolouration of Endodontic Origin (DEO): A State‐of‐the‐Art Review

International Endodontic Journal, EarlyView.
ABSTRACT Background Tooth discolouration of endodontic origin (DEO) refers to an undesirable change in tooth colour arising from the pulp space as a result of reactive physiological processes, pathological processes or endodontic procedures and materials. As DEO frequently affects teeth in the aesthetic zone, it may substantially impair self‐esteem and
