A variety of surgical treatments are used for odontogenic keratocyst (OKC) depending on the clinical and radiographic presentation.

System Dynamics Modeling of Caries Severity States in Long-Term Care.

Dental caries among long-term care (LTC) residents is a persistent and complex problem driven by social and structural factors. Systems thinking may be useful in considering novel approaches to reducing disease. This study aimed to develop a system dynamics model to simulate the progression of dentate older adults in LTC through caries severity states and estimate the effects of 3 intervention scenarios on the progression of caries: preventive topical fluoride (TF), arrest of caries with silver diamine fluoride (SDF), and a combination of TF and SDF.

An Unusual Histopathological Presentation of Mandibular Osteosarcoma.

Jaw osteosarcoma (JOS) is a rare, distinct variant that differ from long bone osteosarcoma (LBOS) in several aspects. JOS typically appears about twenty years later than LBOS, displays a lower propensity for metastasis to other organs, and exhibits better survival rates. The dissimilarities in clinical and biological behavior between JOS and LBOS are likely due, at least in part, to variations in their respective microenvironments.

Efficacy of fluoride varnish containing casein phosphopeptide-amorphous calcium phosphate application and diode laser irradiation on white spot lesions remineralization: An in vitro study.

To describe the demographics of patients younger than 18 years of age who sought dental emergency visits during the COVID-19 pandemic, the treatment provided, the patients' payment sources and the impact of the pandemic on oral health. A retrospective electronic chart review was conducted for dental emergency visits between 2020 and 2023 at the University of Detroit Mercy School of Dentistry, Detroit, Mich., USA.

Comparison between selective laser melted and cast removable partial denture frameworks.

Statement Of Problem: Cast cobalt chromium (Co-Cr) frameworks for removable partial dentures may have undesirable micromechanical properties leading to clinical failures. Co-Cr frameworks made by selective laser melting (SLM) may have improved micromechanical properties, but comparative studies are lacking.

Purpose: The purpose of this in vitro study was to compare the micromechanical properties of SLM for Co-Cr alloys with those produced by conventional casting.

Nonionizing diagnostic imaging modalities for visualizing health and pathology of periodontal and peri-implant tissues.

Radiographic examination has been an essential part of the diagnostic workflow in periodontology and implant dentistry. However, radiographic examination unavoidably involves ionizing radiation and its associated risks. Clinicians and researchers have invested considerable efforts in assessing the feasibility and capability of utilizing nonionizing imaging modalities to replace traditional radiographic imaging.

Does orthodontic treatment using fixed appliances cause initial caries lesions?

Design: Systematic review and meta-analysis of randomized clinical trials (RCTs), non-randomized studies of intervention (NRSIs), cohort and cross-sectional studies. The systematic review was registered in advance on PROSPERO, and was conducted following the Cochrane Handbook of Systematic Reviews of Interventions and PRISMA checklist.

Data Sources: An electronic search in three databases (PubMed, Scopus, and Embase) was conducted by two authors to evaluate studies published from 1990 until May 2023.

Digitally guided root removal and simultaneous implant placement: A case study.

Background: Encountering a retained root tip post-extraction and prior to implant placement is a possible clinical complication. There are numerous approaches for removing retained roots that may be traumatic or atraumatic. Regardless of the approach, careful treatment planning is important to minimize complications, reduce morbidity, and preserve bony structures.

A Novel Diagnostic and Treatment Approach to an Unusual Case of Dens Invaginatus in a Mandibular Lateral Incisor Using CBCT and 3D Printing Technology.

Background: This case report demonstrates the use of three-dimensional (3D) models produced from a cone beam computed tomographic (CBCT) volume to develop a treatment strategy for a rare type of dens invaginatus (DI) in a mandibular incisor.

Methods: A patient with DI Type IIIa presented for endodontic treatment. Following CBCT evaluation, the complex morphologic nature of the invagination required additional diagnostic tools for treatment planning.

Association between dental visits during pregnancy and setting for prenatal care.

Objectives: Federally Qualified Health Centers (FQHCs) may be well positioned to facilitate dental visits during pregnancy for low-income women. We sought to compare receipt of dental visits during pregnancy for women who received prenatal care at an FQHC versus a non-FQHC setting.

Methods: We analyzed Michigan Medicaid administrative data for all live birth deliveries between April 2018 and December 2020.

A Potential Intracanal Medicament, 2-Hydroxyisocaproic Acid (HICA): Cytotoxicity, Genotoxicity, and Its Effect on SCAP Differentiation.

Intracanal medicaments with maximal antimicrobial efficacy and minimal damage to resident stem cells are essential for successful regenerative endodontic procedures. 2-Hydroxyisocaproic acid (HICA) could have the attributes of a potential intracanal medicament. This study evaluates its cytotoxicity, genotoxicity, and effects on the odontogenic and osteogenic differentiation of the stem cells of the apical papilla (SCAP).

Growth Factors Released from Advanced Platelet-Rich Fibrin in the Presence of Calcium-Based Silicate Materials and Their Impact on the Viability and Migration of Stem Cells of Apical Papilla.

Advanced platelet-rich fibrin (A-PRF) provides the scaffold and growth factors necessary for stem cells to proliferate and differentiate in successful regenerative endodontic procedures. This study investigates the release of transforming growth factor-β1 (TGF-β1), platelet-derived growth factor (PDGF), and vascular endothelial growth factor (VEGF) from A-PRF in cell culture media in the presence and absence of mineral trioxide aggregate (MTA) or Biodentine. Additionally, this research assesses the viability and migration of stem cells of the apical papilla (SCAP) in previously conditioned media.

Deer management influences perception of avian plumage in temperate deciduous forests.

Many animals use visual signals to communicate; birds use colorful plumage to attract mates and repel intruders. Visual signal conspicuousness is influenced by the lighting environment, which can be altered by human-induced changes. For example, deer-management efforts can affect vegetation structure and light availability.

ToxR activates the virulence genes by tethering DNA to the membrane through versatile binding to multiple sites.

ToxR, a transmembrane one-component signal transduction factor, lies within a regulatory cascade that results in the expression of ToxT, toxin coregulated pilus, and cholera toxin. While ToxR has been extensively studied for its ability to activate or repress various genes in , here we present the crystal structures of the ToxR cytoplasmic domain bound to DNA at the and promoters. The structures confirm some predicted interactions, yet reveal other unexpected promoter interactions with implications for other potential regulatory roles for ToxR.
