Introduction Regenerative endodontic therapy (RET) has been suggested for treating immature necrotic teeth, and failures after RET may be observed during follow-up examinations, even two years after the initial treatment. The study aimed to examine the outcomes of RET and suggest a decision-making guide for the retreatment of failed cases. Methods Around 414 endodontically treated immature teeth from patients aged six and 17 were screened to identify eight patients who presented with a failed RET.

Nano-mupirocin is a PEGylated nano-liposomal formulation of the antibiotic mupirocin, undergoing evaluation for treating infectious diseases and intratumor bacteria. Intratumoral microbiota play an important role in the regulation of tumor progression and therapeutic efficacy. However, antibiotic use to target intratumoral bacteria should be performed in a way that will not affect the gut microbiota, found to enable the efficacy of cancer treatments.

In Vitro Effect of Streptococcus mutans Biofilm Produced in Sugar-Free Coca-Cola on Enamel.

Int Dent J

June 2024

Department of Prosthodontics, Hadassah Medical Center, Faculty of Dental Medicine, Hebrew University of Jerusalem, In Partial Fulfillment of DMD Requirements, Hebrew University-Hadassah School of Dental Medicine, Jerusalem 91120, Israel.

Article Synopsis
  • Sugary drinks can contribute to dental decay, but sugar-free options like Coca-Cola Zero Sugar (CZ) may seem safer; this study investigates CZ's impact on cavity-causing bacteria and tooth enamel.
  • In the experiment, enamel slabs were exposed to biofilms of Streptococcus mutans and treated with either CZ, hydrochloric acid, or sugar solutions; results showed that CZ supported bacterial growth and lowered pH, indicating harm to the enamel.
  • The findings suggest that sugar-free drinks like CZ might still promote tooth decay, warning dental professionals to inform patients that these beverages can be as damaging to dental health as their sugary counterparts.

Pregnancy trained decidual NK cells protect pregnancies from harmful Fusobacterium nucleatum infection.

PLoS Pathog

January 2024

The Lautenberg Center for General and Tumor Immunology, Institute for Medical Research Israel-Canada, The Hebrew University Hadassah Medical School, Jerusalem, Israel.

Natural killer cells (NKs) found during pregnancy at the maternal-fetal interface named decidual (d)NKs, show signs of education following first pregnancy, resulting in better placentation and fetus-growth, hence termed pregnancy trained dNKs (PTdNKs). Here we show that PTdNKs provide increased protection of the fetus from Fusobacterium nucleatum (FN) infection. We demonstrate that PTdNKs secrete elevated amounts of the bacteriocidal protein granulysin (GNLY) upon incubation with FN compared to dNKs derived from first pregnancies, which leads to increased killing of FN.

Ameloblasts are specialized epithelial cells in the jaw that have an indispensable role in tooth enamel formation-amelogenesis. Amelogenesis depends on multiple ameloblast-derived proteins that function as a scaffold for hydroxyapatite crystals. The loss of function of ameloblast-derived proteins results in a group of rare congenital disorders called amelogenesis imperfecta.

Objectives: To study the association between perforation dental implants into the maxillary sinus cavity and the development of sinus pathology.

Methods: We retrospectively examined 3732 computerized tomography (CT) scans to detect maxillary implants. The detected scans were grouped based on apparent or lack of perforated dental implants in the maxillary sinus (study and control group, respectively).

Studying TIGIT activity against tumors through the generation of knockout mice.

Oncoimmunology

June 2023

The Concern Foundation Laboratories at the Lautenberg Center for Immunology and Cancer Research, Institute for Medical Research Israel Canada (IMRIC), Hebrew University-Hadassah Medical School, Jerusalem, Israel.

The use of antibodies to block inhibitory receptors, primarily anti-PD1 and CTLA4 (known as checkpoint therapy) revolutionized cancer treatment. However, despite these successes, the majority of cancer patients do not respond to the checkpoint treatment, emphasizing the need for development of additional therapies, which are based on other inhibitory receptors. Human TIGIT is an inhibitory receptor expressed by Natural Killer (NK) and T cells and is mainly known to interact with PVR, Nectin-2, Nectin-3, and Nectin-4.

'Adaptable condylectomy' for acquired facial asymmetry and malocclusion caused by temporomandibular joint condylar hyperplasia.

Int J Oral Maxillofac Surg

November 2023

Department of Oral and Maxillofacial Surgery, Hadassah School of Dental Medicine, The Hebrew University, Jerusalem, Israel. Electronic address:

This article describes the 'adaptable condylectomy' and highlights two innovative treatment protocols for the variety of acquired facial asymmetry and associated malocclusion caused by condylar hyperplasia, as illustrated by the cases of seven patients presenting different manifestations of condylar hyperplasia. Protocol I (three cases) is applied for condylar hyperplasia with a normal occlusion and involves a high condylectomy, with the goal of guiding the mandible back to the original occlusion. Protocol II (four cases) is applied for condylar hyperplasia with diverse acquired malocclusions and involves condylectomy at a level adapted to the malocclusion, allowing the mandible to be guided back to the occlusion that pre-existed the active change caused by the condylar hyperplasia, or to a position as close to the midline as possible.

Over the past decades, the main techniques used to visualize bacteria in tissue have improved but are still mainly based on indirect recognition of bacteria. Both microscopy and molecular recognition are being improved, but most procedures for bacteria detection in tissue involve extensive damage. Here, we describe a method to visualize bacteria in tissue slices from an in vivo model of breast cancer.

Intestinal bacterial communities participate in gut homeostasis and are recognized as crucial in bowel inflammation and colorectal cancer (CRC). (), a pathobiont of the oral microflora, has recently emerged as a CRC-associated microbe linked to disease progression, metastasis, and a poor clinical outcome; however, the primary cellular and/or microenvironmental targets of this agent remain elusive. We report here that directly targets putative colorectal cancer stem cells (CR-CSCs), a tumor cell subset endowed with cancer re-initiating capacity after surgery and chemotherapy.
