Physio-Mechanic and Microscopic Analyses of Bioactive Glass-Based Resin Infiltrants.

This study aimed to investigate the efficacy and durability of bioactive glass-based dental resin infiltrants. Resin infiltrants were formulated by combining photoinitiated dimethacrylate monomers with three variations of bioactive glass: 45S5 Bioglass (RIS), boron-substituted (RIB), fluoride-substituted (RIF), and pure resins (PR), whereby TOOTH group (TH) and ICON (CN) served as commercial control groups. Teeth samples were prepared, and experimental and control infiltrants were applied on demineralized human-extracted teeth.

Angiofibroma of the Mandible: Report of a Rare Case.

Angiofibroma is an uncommon, highly vascular benign lesion that occurs in the head and neck region, typically arising in the nasopharyngeal area, potentially with a locally aggressive course. Angiofibroma with a primary intraoral presentation is extremely rare; few case reports have been published in the literature, with only three cases of angiofibroma in the mandible published to date. In this case, a 37-year-old man presented with swelling at the right mandible and underwent enucleation of the lesion under general anesthesia.

Caffeine Consumption Influences Lidocaine Action via Pain-Related Voltage-Gated Sodium Channels: An In Vivo Animal Study.

Several factors might influence the duration and efficiency of local anesthesia. This study investigates the effect of habitual caffeine intake on lidocaine action and explores the potential involvement of voltage-gated sodium channels in the interaction effect. Wistar rats were divided into four groups: (i) control (Ctrl), (ii) lidocaine intraplantar injection (LIDO), (iii) habitual caffeine intake (CAF), and (iv) lidocaine intraplantar injection and habitual caffeine intake (LIDO + CAF).

Unusual collision tumor with infiltrating ductal carcinoma and breast skin squamous cell carcinoma: A case report and literature review.

Introduction: Breast cancer is the most common diagnosed cancer among women worldwide. Invasive ductal carcinoma (IDC) is the most common type, on the other hand, squamous cell carcinoma of the skin (SCC) overlying the breast is a rare tumor. The co-presence of two tumor types in one organ is even a rarer entity, termed as collision tumor.

Salmonella bacilli negative image recognized on Diff-Quik stain from pleural fluid cytology.

Understanding the significance of cytopathological tests in evaluating various infectious processes have become very essential nowadays, as it is a safe, fast, and cost-effective procedure. We present a case of a 52-year-old male with Salmonella empyema where the causative organisms were initially identified on cytology, and subsequently confirmed by microbiological culture. Diff-Quik stained smears showed many colorless, slender, fat short bacilli, which were visualized against the blue-gray background of the smear.
