Objective: Tetraacetylethylenediamine (TAED), a denture cleanser was reported to have a risk of acute side effects at high concentrations. This study evaluated residual TAED from denture cleansers after rinsing for different durations. Methods: The rinsing times of denture cleansers were investigated. Specimens made with the denture base-resin were immersed in a denture cleanser and rinsed with running water. The experimental groups were divided based on the rinsing time; G1 was rinsed for 10 s, G2 for 20 s, G3 for 30 s, and G4 for 60 s. No rinsing was performed in the control group. After the elution of TAED from the samples, quantification was performed using high-performance liquid chromatography and mass spectrometry. Results: Seven denture cleansers were investigated; however, the specific rinsing time was not confirmed. Conversely, the control group had a significantly higher amount of TAED (315.4±104.7 ㎍/L), whereas the other groups with > 10 s rinsing time showed significantly decreased residual TAED. Conclusions: To prevent the potential risks of TAED, users should rinse their dentures thoroughly for ≥ 10 s after using a denture cleanser.

... Previous studies on color changes of teeth associated with food have reported that foods such as red pepper paste, coffee, tea, and instant noodles can cause tooth discoloration [17][18][19][20] . According to a study by Kim et al. 18) , tannin compounds found in coffee and black tea can reduce bacterial plaque in the oral cavity; however, tannins' black pigments can bind to protein components, leading to tooth discoloration and reduced lightness. ...

... The results of this investigation are consistent with previous studies conducted by Põldma, et al. [77], Elkelish, et al. [64], and Hussain, et al. [72] who reported increased amounts of total soluble sugar in Se-treated plants under salt stress conditions. Salt stress increases the production of H₂O₂, which plays a crucial role in cellular contraction, apoptosis, and DNA damage [78]. Enzymatic and non-enzymatic antioxidants can reduce excess H 2 O 2 and diminish stress [79]. ...

... Foods with a pH concentration of 5.5 or below, particularly those with a pH of 4.0, are known to cause dental erosion by dissolving tooth enamel. Numerous studies have reported the impact of low-pH beverages such as energy-, carbonated-, and hangover-relief drinks on teeth and composite resin [8][9][10][11] . Based on these findings, kombucha is also likely to cause dental erosion, including the dissolution of tooth enamel. ...

... The results could act as a significant reference for future studies on M. taiwanensis, including species identification and evaluation of molecular variations between separate geographical locations. C. sinensis were successfully identified by amplification using the ITS gene (Oh et al., 2022). In the same way, the ITS2 gene has also been reported as a molecular marker in the analysis between Opisthorchis felineus and the genus Clonorchis spp. ...

... Thus, we confirmed the changing pattern of parasite infection prevalence throughout the Joseon period to 21st century in Korea reported by Seo et al. [1]. Briefly, the infection prevalence of the trematodes C. sinensis and P. westermani was lower than that of the Mummy parasitism results of (1)-(26) represent the existing corpus on Joseon mummy parasitism [1,8]. The current results are (27)-(30). ...

... Herbal medicines, in particular, have a variety of biological activities and fewer side effects and are thought to control and treat various diseases via different mechanisms 14,15) . Rosmarinic acid (-o-caffeoyl-3,4-dihydroxyphenyl-lactic acid; RA) is a natural phenolic substance contained in rosemary, basil, and mint, and has therapeutic potential with anti-oxidative, anti-bacterial, anti-viral, anti-inflammatory, and anti-mutagenic activities [16][17][18] . Recently, RA has been reported to increase alkaline phosphatase activity and bone mineralization for bone formation and prevent osteoporosis 16,19) , however, the cellular targets of RA in the bone are poorly understood. ...

... Previous studies have applied various methodologies, such as multiple regression, logistic regression, and machine learning, to identify determinants affecting the LOS [1][2][3][4], and to predict LOS [5][6][7][8][9][10][11]. However, these approaches often fail to account for censored data or the survival period of inpatients. ...
