A combined study including selective angiography of the liver and spleen, angioscintigraphy with 99mTc-TCK-5, polypositional scintigraphy with 99mTc-frosstimag-phytate, and ultrasonic scanning was conducted to detect specific liver and splenic involvement in 57 patients with Hodgkin's disease, CT was performed in 4 patients. A high diagnostic value of all methods was shown in macronodal liver involvement (node sizes over 3 cm); of ultrasonic scanning--in the detection of nodes in the liver (node sizes from 1 to 3 cm); of ultrasonic scanning, angiography and angioscintigraphy--in nodal splenic involvement. Signs of diffuse-infiltrative liver involvement detected in angiography and angioscintigraphy were described. The informative value of ultrasonic scanning and CT in this type of involvement was much lower.

Tooth autotransplantation is widely used to replace congenitally missing teeth or teeth with irreversible damage. This case report presents a personalized ultrasonic osteotome that enables precise preparation, minimizes bone trauma, enhances the initial stability of the transplanted tooth, and contributes to a favorable prognosis. The procedure is as follows: a 25-year-old female patient presented with a porcelain-fused-to-metal crown on Tooth #19, which had detached due to severe decay, rendering the tooth unsalvageable.

One area of technological advancement has been the shift from stainless steel hand tools to nickel-titanium (Ni-Ti) rotary tools. This paper aims to perform an in vitro comparative study to evaluate the efficacy of five endodontic manual and rotary instruments such as Kerr files, Orodeka Plex V, ProTaper Flydent NiTi super files, and ProTaper Flydent NiTi super files in combination with an ultrasonic endodontic E3D Diamantata EMS scaler used for root canal shaping. The following aspects were highlighted: effective removal of smear layer (SL) from the dentinal tubules in the coronal 1/3, middle 1/3, and apical 1/3 of the root canal, appearance of cracks in the dentinal walls by SEM analysis, and highlighting of dentin mineral content and remnant debris by EDX analysis.

Background: This work intended to assess the disinfection efficacy of hypochlorous acid (HA) and silver nanoparticles (AgNP) disinfectants in disinfecting the dental unit waterlines (DUWL) during comprehensive oral treatment and explore their potential applications in the oral medical environment.
Methods: Firstly, AgNP solution was prepared and evaluated through X-ray diffraction (XRD), field emission transmission electron microscope (FE-TEM), and stability tests. Subsequently, 15 dental units were selected and randomly assigned to three groups, each receiving a different disinfection method.

Polysaccharides from the dried tuber of Typhonium giganteum Engl. (TGEPs) were obtained by utilizing ultrasonic-assisted extraction (UAE) as the extraction method. The determination of optimal process parameters for the UAE of TGEPs (TGEP-U) was accomplished through the application of response surface methodology (RSM).

Objective: This study investigated the associations among endodontic instruments, ultrasonic tips and various final irrigation protocols for removing intracanal and intratubular biofilms in long oval canals.
Methodology: One hundred mandibular premolars inoculated with Enterococcus faecalis were divided into two groups: the control group (CG: n = 10), which received no treatment; and the test groups (n = 30), which included saline (SS), sodium hypochlorite (2.5% NaOCl) and chlorhexidine (2% CHX).
