Compositional Differences within the Human Molar Dentin Detected byMicro-FTIR

Arata Watanabe, Tetsuro Kôno, Toshiro Sakae, Hiroyuki Okada

Although numerous studies on dental caries have been reported, they have been inconclusive and have not clarified the mechanism of caries progression in a unified manner. Fourier transform infrared spectroscopy（FTIR）is one of the most convenient and reliable methods for quantitative and qualitative …

Lipopolysaccharides derived from Porphyromonas gingivalis and Escherichia coli: Differential and interactive effects on novelty-induced hyperlocomotion, blood cytokine levels and TLR4-related processes

Yuri Aono, Koji Saito, Hiroki Kawashima, Arata Watanabe et autres

Lipopolysaccharide (LPS), a component of the Gram-negative bacterial cell wall, activates Toll-like receptors (TLRs). Porphyromonas gingivalis (Pg) may be involved in the progression of periodontal disease. Mice exposed to a novel environment show hyperlocomotion that is inhibited by systemic administration of LPS …

Impact of Surgical Timing on Functional Outcomes after Anterior Cruciate Ligament Reconstruction

Tatsuhiro Kawashima, Hirotaka Mutsuzaki, Arata Watanabe, Kotaro Ikeda et autres

Objectives: Although acute anterior cruciate ligament reconstruction (ACLR) is often avoided because of postoperative joint stiffness, delayed ACLR can lead to a longer recovery time and can have a negative impact on physical function due to detraining. This study aimed to determine …

Use of Unidirectional Porous β-Tricalcium Phosphate in the Tibial Tunnel for Anterior Cruciate Ligament Reconstruction: A Case Series

Arata Watanabe, Naoya Kikuchi, Takumi Ichihara, Hiroshi Kumagai et autres

Bone defects in the tibial tunnel for anterior cruciate ligament (ACL) reconstruction can cause adverse events. The unidirectional porous tricalcium β-phosphate (UDPTCP) has the potential to be used as a filling substitute for bone defects. In this case series, we present the …

Compositional Changes after Heating of Enamel Crystals Demineralized by Soft Drink

Arata Watanabe, Tetsuro Kôno, Takahiro Ogawa, Yuya Togashi et autres

To date, significant research has been conducted on biological apatite, the composition of which deviates considerably from that of hydroxyapatit（eCa（POl0 4）（6 OH）2）. Our previous studies have shown individual differences in the composition of biological apatite in human enamel and diversity in enamel. …

Fractalkine’s dual role in inflammation and hard tissue formation in cultured human dental pulp cells

Natsuko GOMYO-FURUYA, Naoto Kamio, Takahiro Watanabe, Tomomi Hayama et autres

This study aimed to explore the potential roles of fractalkine/CX3CR1, primarily expressed in vascular endothelial cells and has recently been identified in dental pulp cells at sites of pulp tissue inflammation, not only in inflammation but also in pulp hard tissue formation. …

The Mechanism of Inflammation Caused by Oral Infection with Fusobacterium nucleatum in Periodontal Tissue

Miyuki Toda, Ryoki Kobayashi, Tomoko Kurita‐Ochiai, Tetsuro Kôno et autres

We have previously reported that oral inoculation with Fusobacterium nucleatum（F. nucleatum）caused horizontal bone resorption and increases the RANKL/OPG ratio. However, the mechanism of periodontitis induction by F. nucleatum was unknown. This study investigated how oral inoculation with F. nucleatum induced periodontitis. Mice …

Fusobacterium nucleatum Induces Gut Dysbiosis and Inflammasome and Promotes Colonic Inflammation

Miyuki Toda, Ryoki Kobayashi, Tomoko Kurita‐Ochiai, Tetsuro Kôno et autres

We previously reported that oral inoculation of the oral commensal bacteria Fusobacterium nucleatum（F. nucleatum）induced periodontitis and disrupts the intestinal im mune response. However, the effect of the intestinal microfloral balance, inflammation of the intestinal tract, and the mechanism of periodontitis induction by …
