Methods: A retrospective analysis of the DAP values of 3568 CBCT examinations taken from two different devices at the Prince Philip Dental Hospital, Hong Kong between 2016 and 2021 was performed. Patient- (age, gender, and imaging indication) and imaging-related (CBCT device, field-of-view (FOV), and voxel size) were correlated with the DAPs. The indication-oriented third-quartile DAP values were compared with DRLs from the UK, Finland, and Switzerland. The obtained third-quartile DAPs lower than the national DRLs and those for which no national DRLs have been proposed were used to establish institutional DRLs. Results: In the investigated CBCTs, the DAP value for large FOV scans was significantly lower than medium/small FOVs. CBCTs with...

Methods The orthogonal experimental design was used to investigate the effect of three factors on the bioeffects of four cell lines under three levels. Three factors included microbubble concentration, sound intensity, irradiation time. Human breast tumor (MCF-7) cells, ovarian tumor (A2780) cells, liver tumor (Bel7402) cells and thyroid tumor (ARO) cells were exposed to ultrasound in the presence of SonoVue. The cell survival rate was determined by MTT methods and the cell luminosity factor was detected by flow cytometry. Results The optimum parameters for Bel7402 and ARO cell were the same(A2B3C2), and they were different from those from MCF-7(A3B1C1) and A2780(A1B3C3) cell. The cell survival rates for 4 cell lines were above 75%, and the cell luminosity factors were different among 4 cell lines. Conclusions The optimum parameters by ultrasound-mediated microb...

Materials and Methods Cone-beam computed tomography (CBCT) scans exhibiting bilateral maxillary sinuses that were acquired from January 2016 to February 2019 were initially screened. A total of 227 scans (454 sinuses) that fulfilled the inclusion criteria were included. The presence, location, and volumetric characteristics of the diagnosed MRCs were evaluated on CBCT images using the 3D-Slicer software platform. The presence of MRCs was correlated with potential influencing factors including age, sex, and dentoalveolar pathology. For MRCs located on the sinus floor, factors with a potential impact on the volume, surface, and diameter were analyzed. Results An MRC was present in 130 (28.6%) of the 454 sinuses. Most MRCs were located on the sinus walls and floor. The mean MRC ...

MATERIALS AND METHODS The Collection originates from the 1980s and became officially established in 2017 for teaching and research purposes. Most of the Collection consists of unclaimed human remains of southern Chinese individuals exhumed from local cemeteries and donated to the Faculty in the last few decades. The demographic information was provided largely from burial records and forensic estimations. Since 2016, the Collection has undergone a process of reorganization into cranial and postcranial remains, followed by preservation procedures that included cleaning and classification. RESULTS The Collection currently consists of remains belonging to about 368 individuals (243 males, 54 females, 71 unknown), with ages ranging from 0.8 to 90 years (mean 57.4 years). It comprises cranial remains belonging to 260 individuals (169 males...
