Promoting Surface Energy and Osteoblast Viability on Zirconia Implant Abutments Through Glass-Ceramic Spray Deposition Technology.

Zirconia is used widely for high-precision custom abutments; however, stress concentration can compromise osseointegration. Although glass-ceramic spray deposition (GCSD) can enhance the surface properties of zirconia, its biological effects remain unclear. In this study, the biological responses of human osteoblast-like (MG-63) cells to GCSD-modified zirconia surfaces were evaluated to assess the potential application in zirconia abutments.

Impacts of surface characteristics on biological responses and biofilm formation of 3D-printed denture base resins: An in vitro study.

Background/purpose: With advancements in digital technology, fully digital workflow for complete denture fabrication using 3D-printed denture base resin (DBR) has gained increasing clinical acceptance in recent years. However, the surface characteristics, biocompatibility, and biofilm formation of 3D-printed DBR materials remain insufficiently understood. Therefore, in this study, we investigated and analyzed these aspects.

Comparative Evaluation of Dental Clinical Surface Treatments for Polyetheretherketone with Airborne-Particle Abrasion, Hydrofluoric Acid Etching, and Handheld Nonthermal Plasma Activation on Long-Term Bond Performance.

Polyaryletherketone (PAEK) materials, including polyetheretherketone (PEEK) and polyetherketoneketone (PEKK), possess excellent mechanical properties and biocompatibility; however, their inherently low surface energy limits effective bonding with resin cements. This study investigated the effects of hydrofluoric acid (HF) etching and handheld nonthermal plasma (HNP) treatment on enhancing the adhesive performance of PAEK surfaces. Disk-shaped PEEK (BP) and PEKK (PK) specimens were divided into four groups: APA (airborne-particle abrasion), PLA (nonthermal plasma treatment), LHF (5.

Effects of handheld nonthermal plasma on the biological responses, mineralization, and inflammatory reactions of polyaryletherketone implant materials.

Background/purpose: The handheld nonthermal plasma (HNP) treatment may alter the surface properties, bone metabolism, and inflammatory reactions of polyaryletherketone (PAEK) dental implant materials. This study tested whether the HNP treatment might increase the biocompatibility, surface hydrophilicity, surface free energies (SFEs), and the cell adhesion and mineralization capability of PAEK materials.

Materials And Methods: Disk-shaped samples of titanium (Ti), zirconia (Zr), polyetheretherketone (PEEK [PE]), and polyetherketoneketone (PEKK [PK]) were subjected to HNP treatment and termed as TiPL, ZrPL, PEPL, and PKPL, respectively.

A Narrative Review: Repurposing Metformin as a Potential Therapeutic Agent for Oral Cancer.

Oral cancer, particularly oral squamous cell carcinoma (OSCC), is a significant global health challenge because of its high incidence and limited treatment options. Major risk factors, including tobacco use, alcohol consumption, and specific microbiota, contribute to the disease's prevalence. Recently, a compelling association between diabetes mellitus (DM) and oral cancer has been identified, with metformin, a widely used antidiabetic drug, emerging as a potential therapeutic agent across various cancers, including OSCC.

Magnolol's Therapeutic Efficacy and Immunomodulatory Effects in Oral Squamous Cell Carcinoma.

Background/aim: Oral squamous cell carcinoma (OSCC) presents a significant health challenge, requiring effective treatments. Magnolol, a compound with potential anticancer properties, warrants investigation in OSCC treatment. Here, we aimed to assess the efficacy of magnolol in inhibiting progression of OSCC and to explore the underlying mechanisms of its action.

Court decisions in criminal proceedings for dental malpractice in Taiwan.

Background/purpose: Malpractice claims place heavy economic and emotional burdens on both dentists and patients. Recently, medical malpractice lawsuits are decreasing in prevalence but increasing in severity. The percentage of dental malpractice payments is also growing among the health profession.

Association between Periodontal Disease and Subsequent Sjögren's Syndrome: A Nationwide Population-Based Cohort Study.

Xerostomia (dry mouth) is the cardinal symptom of Sjögren's syndrome (SS), which is an autoimmune disease involving the exocrine glands and other organs. Xerostomia may predispose patients to periodontal disease (PD) and an association between SS and PD has been reported. This association may be bidirectional; therefore, we conducted this study to investigate the risk of SS in patients with PD using data from the National Health Insurance Research Database of Taiwan.

Associations between dental anxiety and postoperative pain following extraction of horizontally impacted wisdom teeth: A prospective observational study.

The aim of the study is to identify associations between dental anxiety and postoperative pain in patients undergoing extraction of horizontally impacted wisdom teeth.A total of 119 volunteers provided demographic data, and completed questionnaires, the State-Trait Anxiety Inventory (STAI), Chinese Index of Dental Anxiety and Fear (C-IDAF)-4C, and the Numeric Rating Scale (NRS) for pain.Mean SAI, TAI, and C-IDAF-4C scores were 42.

Reliability and validity of DS-ADHD: A decision support system on attention deficit hyperactivity disorders.

Background And Objectives: The purpose of this study is to examine the reliability of the clinical use of the self-built decision support system, diagnosis-supported attention deficit hyperactivity disorder (DS-ADHD), in an effort to develop the DS-ADHD system, by probing into the development of indicating patterns of past screening support systems for ADHD.

Methods: The study collected data based on 107 subjects, who were divided into two groups, non-ADHD and ADHD, based on the doctor's determination, using the DSM-IV diagnostic standards. The two groups then underwent Test of Variables of Attention (TOVA) and DS-ADHD testing.

Predicting the severity and prognosis of trismus after intensity-modulated radiation therapy for oral cancer patients by magnetic resonance imaging.

To develop magnetic resonance imaging (MRI) indicators to predict trismus outcome for post-operative oral cavity cancer patients who received adjuvant intensity-modulated radiation therapy (IMRT), 22 patients with oral cancer treated with IMRT were studied over a two-year period. Signal abnormality scores (SA scores) were computed from Likert-type ratings of the abnormalities of nine masticator structures and compared with the Mann-Whitney U-test and Kruskal-Wallis one-way ANOVA test between groups. Seventeen patients (77.

Clinical effectiveness, toxicity, and failure patterns of helical tomotherapy for postoperative oral cavity cancer patients.

Background: The outcome of postoperative high- and intermediate-risk oral cavity cancer (OCC) patients receiving helical tomotherapy (HT) remains limited.

Materials And Methods: Between November 2006 and November 2012, 53 postoperative high- and intermediate-risk OCC patients treated with HT were enrolled.

Results: The 4-year locoregional, local, and regional control rates were 66%, 76.
