The purpose of this study was to evaluate the effects of commercialized denture adhesives and mouth moisturizers using direct and indirect cell cultures for in vitro examinations with human fibroblast and epithelial cells. Denture adhesives (Faston, Poligrip Powder, New Poligrip Free, Tafugurippu Kurimu, Polident Adhesive, Tafugurippu Tomei) and mouth moisturizers (Concool Mouth Gel, Biotene Oral Balance Gel) were subjected to live and dead detection and pH level determination. The mouth moisturizers showed higher cytotoxicity effects comparing with control on every cell cultures and cells, and pH level did not show any significant differences. However, there was no correlation of type of denture adhesive or mouth moisturizer with cytotoxicity. We concluded that cytotoxicity affects human cells regardless of type of material, though some dependence was noted.

Article Synopsis
- A study investigated how nanosilica content and environmental pH affect the fracture resistance and moisture absorption of polymethyl methacrylate (PMMA) resin, revealing significant interactions between these factors.
- The research involved creating 90 resin specimens with varying nanosilica percentages and measuring their performance under different pH levels, following specific testing standards.
- Results showed that both nanosilica levels and pH significantly influenced fracture toughness, with a negative correlation found between moisture absorption and fracture toughness.

Background: The wet-bonding protocol has been used in the etch-and-rinse (ER) mode to maintain adhesive infiltration in demineralized dentin. This study answered the research question: "Do the retention rates and other secondary outcomes of composite restorations in non-carious cervical lesions (NCCLs) differ between dry- and wet-bonding techniques?"
Methods: The authors included randomized clinical trials in which NCCLs were restored with ER or universal adhesives applied under dry and moist dentin. Searches for eligible articles were performed in MEDLINE via PubMed, Web of Science, Cochrane Library, Brazilian Library in Dentistry, Latin American and Caribbean Health Sciences Literature, Scopus, Embase, and grey literature without language and date restrictions and updated in May 2024.
Relationship among cancer treatment, quality of life, and oral function in head and neck cancer survivors: A cross-sectional study.

Department of Preventive Dentistry, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, 2-5-1 Shikata-Cho, Kita-Ku, Okayama, 700-8558, Japan.
Purpose: Treatment for head and neck cancer (HNC), such as surgery and chemoradiotherapy, can reduce oral function and affect quality of life (QoL). However, whether HNC treatment affects QoL via the decline of oral function remains unclear. This study aimed to investigate the relationship among cancer treatment, QoL, and actual oral function in HNC survivors.

Article Synopsis
- The Japanese quail has been significant to humans since the 12th century, known for its high egg production, quality low-fat meat, and ease of management, making it valuable in both industry and research.
- A study focused on the development of the oropharyngeal salivary glands in Japanese quails, examining embryos and chicks at various ages using histological and electron microscopy techniques.
- Key findings included the early formation of sublingual and mandibular glands, which developed into mucous glands after hatching, playing important roles in food processing and moisture retention during feeding.

To explore the digital design and fabrication technology of personalized restorative matrix for dental filling, and to explore the feasibility of direct resin restoration for deep caries lesions in distal neck of mandibular second molar. For patients with deep caries lesions in the distal neck of the mandibular second molar who visited the Department of Cariology and Endodontology of Peking University School and Hospital of Stomatology from September 2023 to April 2024, after preparing the cavity and gingival retractor, a three-dimensional intraoral scanner was used to obtain three-dimensional data of the patient's dentition. In the dental restoration computer-aided design software, the inlay function was used to generate the restored tooth morphology.
