Comparative study of pulpal response following direct pulp capping using synthesized fluorapatite and hydroxyapatite nanoparticles.
BMC Oral Health
January 2025
Basic Dental Sciences Department, Faculty of Dentistry, Zarqa University, PO Box 2000, Zarqa, 13110, Jordan.
Objective: This study aimed to investigate and compare the histological response of rabbit dental pulp after direct pulp capping with 3 different materials: mineral trioxide aggregate (MTA), nanoparticles of fluorapatite (Nano-FA), and nanoparticles of hydroxyapatite (Nano-HA) after 4 and 6-week time intervals.
Material And Methods: A total of 72 upper and lower incisor teeth from 18 rabbits were randomly categorized into 3 groups)24 incisors from six rabbits each. MTA Group: teeth were capped with MTA.
Determination of streptococcus mutans retention in acidic and neutral pH artificial saliva environment of all-ceramic materials with different surface treatment.
BMC Oral Health
January 2025
Department of Basic Medical Science, Faculty of Medicine, Yozgat Bozok University, Yozgat, 66100, Türkiye, Turkey.
Background: Although surface finishing processes are effective against Streptococcus mutans biofilm, the mechanism of action of saliva with different acidity values has not been studied in detail. This study aims to produce four different all-ceramic materials in a single session with CAD/CAM devices and apply two different surface finishing processes, glazing and polishing, and then determine the retention of Streptococcus mutants on the surfaces of the materials in saliva with varying levels of acidity.
Methods: Zirconia-reinforced lithium silicate (Vita Suprinity, Vita Zahnfabrik, Bad Saöckingen, Germany), monochromatic feldspar (Vitablocs Mark 2, Vita Zahnfabrik, Bad Saöckingen, Germany), leucite glass ceramic (IPS Empress CAD, Ivoclar Vivadent, Liechtenstein), and monolithic zirconia (Incoris TZI (Cerec) Sirona, Germany) were used in the study.
Assessing the photodegradation efficiency of benzene, toluene, and xylene (BTX): A comparative investigation using activated charcoal (AC), zeolitic imidazolate framework-8 (ZIF-8), and zirconium metal-organic framework (Zr-MOF).

In this study, three different materials were investigated for their ability to degrade benzene, toluene, and xylene (BTX) using light energy. The materials studied were activated charcoal (AC), zeolitic imidazolate framework (ZIF-8), and zirconium metal-organic framework (Zr-MOF). Initially, AC, ZIF-8, and Zr-MOF were characterized using X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), Brunauer-Emmett-Teller (BET) surface area analysis, and spectroscopic analysis techniques.

The treatment of effluents from the pharmaceutical industry currently remains a major challenge due to their impact on the environment and public health along with the cost of treatments. Considering these issues, our work focused on the development of materials with effective adsorption properties to treat industrial effluents based on locally available and inexpensive clays and zeolite. Local Algerian kaolin (Djebel Debbagh), palygorskite (Ghoufi) and zeolite (Tinbdar) were treated thermally and chemically prior to synthesis into mesoporous materials of hexagonal structure using pluronic P123 as surfactant.

Room-temperature phosphorescent (RTP) carbon dots (CDs) demonstrate significant potential applications in the field of information anticounterfeiting due to their excellent optical properties. However, RTP emission of CDs remains significantly limited due to the spin-forbidden properties of triplet exciton transitions. In this work, an in situ nitrogen doping strategy was employed to design and construct strong spin-orbit coupling nitrogen-doped CDs with mesoporous silica with alumina (N-CDs@MS@AlO) RTP composites.
