Abstract	Heat-pressed lithium disilicate (LDS)-based glass–ceramic ingots are widely used for the fabrication of dental restorations. Repressing or repeat processing the remaining parts of these ingots has been reported to not adversely affect their mechanical properties. However, there is not enough information on the stainability of crowns constructed from these repeated heat-processed LDS ceramic ingots. Seventy-two identical ceramic crowns were constructed from three different repeated heat-processed LDS ceramic ingots representing three groups (n = 24): E-max (Ivoclare), Lisi (GC), and Celtra (Dentsply Sirona). Each group was subdivided into two subgroups (n = 12) representing experimental (coffee) and control groups. Color changes were assessed according to the CIE L * a * b * system and measured initially, after coffee staining and after brushing. All groups were susceptible to staining; however, they showed different behaviors with respect to the three axes of the CIE L * a * b * system. In general, immersion in coffee followed by brushing decreased the staining of all tested ceramic crowns to the acceptability threshold of color change (ΔE = 2.7). Routine brushing of coffee-stained ceramic crowns made from repeatedly processed LDS, LDS-HDM, and ZLS ceramic ingots restored their color to clinically acceptable levels.

Abstract	Background: Transurethral resection of bladder tumors (TURBT) is the standard management for urinary bladder tumors; however, new techniques as Thulium laser Objectives: In this study safety, efficacy, and tumor recurrence after TmLRBT and TURBT were prospectively compared in patients with primary (<4 cm) bladder tumors. Patients and methods: Between August 2019 and May 2021, patients with primary (<4 cm) bladder tumors were enrolled. Patients were randomized between the two procedures. All perioperative data were collected prospectively. Pathological specimen findings and recurrence rates were reported during follow-up visits. Results: Sixty patients underwent TURBT, and another 60 had TmLRBT. No significant differences were detected in patient demographics or preoperative tumor characteristics between the two groups. Operation time was less (28.2 vs. 38.9 min, Conclusion: In this study, TmLRBT showed reduced operative time with lower perforation rates. Higher detection of detrusor muscle and less tissue destruction in the pathological specimen were obtained with TmLRBT, as well as lower rates of tumor recurrence. These findings suggest that TmLRBT is a safe and efficacious substitute to TURBT in tumors <4 cm.

Abstract	Background: Scheduled maintenance appointments after periodontal treatment are very much critical for the success of the treatment. This is necessary for patients seeking to prevent disease recurrence and maintain oral health. Materials and methods: In this study, we conducted a comprehensive analysis to assess the efficacy of various maintenance intervals in preventing disease recurrence among patients with a history of periodontal treatment. We gathered data from a diverse group of patients who had undergone periodontal treatment and tracked their oral health over an extended period. Results: Our findings reveal compelling insights into the optimal maintenance intervals. Patients who attended maintenance appointments at three-month intervals showed a significant reduction in disease recurrence by 40%, compared to those at six-month intervals. Moreover, those on annual intervals experienced a disease recurrence rate of 60. Conclusion: In conclusion, our study underscores the importance of regular maintenance appointments after periodontal treatment. Patients who attend appointments every three months have a significantly lower risk of disease recurrence. These findings emphasize the need for tailored maintenance schedules to ensure long-term oral health.

Abstract	Statement of problem: Agreement on the perfect virtual cement space value for computer-aided design and computer-aided manufacturing (CAD-CAM) implant-supported resin-ceramic crowns with the best marginal adaptation is lacking. The range of cement gap settings in some CAD design software programs is wide (0 to 200 μm), and manufacturer recommendations regarding the best cement gap setting for certain types of ceramics is not specific. Purpose: The purpose of this in vitro study was to evaluate the effect of virtual cement gap settings on the marginal fit of cemented resin-ceramic crowns on implant abutments. Material and methods: Thirty implant analogs and matching stock abutments were coupled and implanted into autopolymerizing acrylic resin blocks. Three groups (n=10) of resin-ceramic molar crowns with 3 different virtual cement space settings (40, 60, and 100 μm) were designed by using a CAD design software program. The crowns were cemented over their corresponding abutments under a static load by using a specially designed cementing device. A scanning electron microscope was used to measure the mean vertical marginal gap (MG) for each group, where a total of 120 measurements for each of the 3 groups (12 sites per crown and 10 crowns per group) were evaluated. One-way analysis of variance and the post hoc Tukey pairwise comparison tests were used to analyze the data (α=.05). Results: A significant difference (P<.001) was found between the MG values of the resin-ceramic implant-supported crowns fabricated by using the 3 cement space settings. The smallest MG was obtained with the 60-μm setting as compared with the 40-μm and 100-μm settings. Conclusions: A limited inverse relation was found between the MGs of CAD-CAM-fabricated resin-ceramic implant-supported crowns and the cement gap settings in the exocad software program. The smallest MGs were obtained when a 60-μm cement space value was used (P<.001).

Abstract	Introduction: Oral domperidone is a prokinetic drug that enhances gastric emptying, which has a positive effect in decreasing gastric residual volume (GRV), subsequently decreasing the risk of pulmonary aspiration. This study aimed to assess the effect of preoperative oral domperidone on gastric residual volume, detected by ultrasound for patients undergoing elective surgery under general anesthesia. Material and methods: This randomized double-blinded controlled placebo trial was conducted in 40 patients who were randomly assigned to two equal groups: the domperidone group (D) ( n = 20): patients received 400 mL of apple juice as a clear fluid, two hours preoperatively, and an oral domperidone 10 mg tablet; and the placebo group (P) ( n = 20): patients received 400 mL of apple juice as a clear fluid two hours preoperatively with a placebo tablet. Gastric residual volume detected by ultrasound was the primary outcome and postoperative nausea and vomiting (PONV) was the secondary outcome. Results: There was no statistically significant difference in the mean gastric residual volume detected by ultrasound between groups after 1 hour ( P > 0.05). However, the mean gastric residual volume detected by ultrasound after 2 hours was statistically significantly lower with domperidone (55.95 ± 6.72 mL) than with the placebo group (70.22 ± 13.00 mL) ( P < 0.05). There was no statistically significant difference between groups regarding PONV, with a P -value > 0.05. Conclusions: Preoperative oral domperidone intake was effective in decreasing the GRV measured by ultrasound.

Abstract	Background: This study evaluates the implications of blood pressure homeostasis in bilateral vs. unilateral carotid surgeries, focusing on the incidence of postoperative hypertension, hyperperfusion syndrome, and stroke as primary outcomes. It further delves into the secondary outcomes encompassing major adverse cardiovascular events and all-cause mortality. Methods: Spanning two decades (2002-2023), this comprehensive retrospective research encompasses 15,369 carotid referrals, out of which 1,230 underwent carotid interventions. A subset of 690 patients received open carotid procedures, with a 10-year follow-up, comprising 599 unilateral and 91 bilateral surgeries. The Society for Vascular Surgery Carotid Reporting Standards underpin our methodological approach for data collection. Both univariate and multivariate analyses were utilized to identify factors associated with postoperative hypertension using the Statistical Package for the Social Sciences (SPSS) Version 22 (SPSS®, IBM® Corp., Armonk, N.Y., USA). Results: A marked acute elevation in blood pressure was observed in patients undergoing both unilateral and bilateral carotid surgeries ( Conclusion: The study identifies postoperative hypertension as a crucial independent predictor of perioperative stroke following bilateral carotid surgery. Moreover, the study elucidates the significant impact of bilateral CEA on the development of post-operative hyperperfusion syndrome or stroke, as compared to unilateral CEA. Currently almost 90% of our carotid practice is eversion carotid endartrerectomy.

Abstract	Introduction: Neural crest cells (NCCs) are multipotent and are attributed to the combination of complex multimodal gene regulatory mechanisms. Cardiac neural crest (CNC) cells, originating from the dorsal neural tube, are pivotal architects of the cardio-neuro-vascular domain, which orchestrates the embryogenesis of critical cardiac and vascular structures. Remarkably, while the scientific community compiled a comprehensive inventory of neural crest derivatives by the early 1980s, our understanding of the CNC's role in various cardiovascular disease processes still needs to be explored. This review delves into the differentiation of NCC, specifically the CNC cells, and explores the diverse facets of non-syndromic cardiovascular neurocristopathies. Methods: A systematic review was conducted as per the PRISMA Statement. Three prominent databases, PubMed, Scopus, and Embase, were searched, which yielded 1,840 studies. We excluded 1,796 studies, and the final selection of 44 studies formed the basis of this comprehensive review. Results: Neurocristopathies are a group of genetic disorders that affect the development of cells derived from the NC. Cardiovascular neurocristopathy, i.e., cardiopathy and vasculopathy, associated with the NCC could occur in the form of (1) cardiac septation disorders, mainly the aortico-pulmonary septum; (2) great vessels and vascular disorders; (3) myocardial dysfunction; and (4) a combination of all three phenotypes. This could result from abnormalities in NCC migration, differentiation, or proliferation leading to structural abnormalities and are attributed to genetic, familial, sporadic or acquired causes. Discussion: Phenotypic characteristics of cardiovascular neurocristopathies, such as bicuspid aortic valve and thoracic aortic aneurysm, share a common embryonic origin and are surprisingly prevalent in the general population, necessitating further research to identify the underlying pathogenic and genetic factors responsible for these cardiac anomalies. Such discoveries are essential for enhancing diagnostic screening and refining therapeutic interventions, ultimately improving the lives of individuals affected by these conditions.
