Over the past years, immunotherapy remains an evolving treatment modality for these patients. This meta-analysis was performed to comprehensively evaluate the efficacy and safety of immune checkpoint inhibitors. For this purpose, 18 clinical trials comprising a total of 3,144 patients were identified from the PubMed database up to September 2020. Overall, the objective response rate (ORR) to PD-1/PD-L1 inhibitors was 0.20 [95% confidence intervals (CI) 0.17-0.23]. Furthermore, the pooled 1-year overall survival (OS) and 1-year progression-free survival (PFS) rates were 0.43 (95% CI 0.33-0.53) and 0.19 (95% CI 0.17-0.21), respectively. The summary rates of any-grade and grade ≥3 adverse events (AEs) were 0.66 (95% CI 0.58-0.74) and 0.13 (95% CI 0.09-0.18), respectively. Among the different subgroups, PD-1/PD-L1 inhibitors elicited a promising ORR in patients with lymph node-only metastasis compared to those with visceral metastasis (0.41 VS. 0.17). Additionally, patients with primary tumor in the lower tract had higher ORR compared to those with primary tumor in the upper tract (0.24 VS. 0.15). Briefly speaking, this immunotherapy protocol showed an encouraging efficacy and acceptable safety profile in the treatment of advanced UC. Moreover, our findings provided potential clinical significance for patients with lymph node-only metastasis or primary tumor in the lower tract. However, these exciting findings need further confirmation.The objective of this study was to evaluate the antibacterial effect of a green tea infusion used as a mouthwash. In this double-blind, randomized controlled study, simple randomization was used to divide 28 students, 18 to 40 years of age, into 2 groups (n = 14) green tea (intervention) or distilled water (placebo). A 13% green tea infusion was prepared with 13 g of green tea (commercially fractionated) in 100 mL of saline solution at a temperature of approximately 90°C. The liquid was poured into sterile glass containers, as was the distilled water for the control group. The antibacterial effect was determined by counting the colony-forming units in cultures of plaque and saliva samples, which were obtained before and immediately after the students rinsed their mouth once with 10 mL of the green tea or control solution. The data were subjected to t tests to analyze differences before and after the intervention and between groups (green tea versus distilled water) (P less then 0.05). The analysis showed statistically significant differences between the groups (P less then 0.05), with participants in the green tea group demonstrating greater reductions in the numbers of colony-forming units. Green tea mouthwash had an antibacterial effect on saliva and bacterial plaque, suggesting that green tea mouthwash could be a beneficial addition to standard oral hygiene measures. Trial registration ClinicalTrials.gov Identifier NCT04410666.The aim of this in vitro study was to evaluate the effect of different periods of intracanal calcium hydroxide (Ca[OH]2) dressing application on the compressive strength of root dentin. The roots of 80 human mandibular premolars were prepared via the crown-down technique and randomly distributed into 1 control group (Gc) and 4 experimental groups (n = 16). The experimental groups were based on the length of intracanal Ca(OH)2 dressing use 7 (G7d), 14 (G14d), 30 (G30d), or 90 (G90d) days. The prepared roots in the control group were left unfilled. The root canals in the experimental groups were dried, filled with the Ca(OH)2 dressing, and radiographed, and then the root canal entrance was sealed. All of the specimens were stored in saline solution at 37°C for the duration of their experimental period. After storage, the roots were sectioned with 2 cuts. The first cut was 1 mm below the cementoenamel junction, and the second was 6 mm apical to the first cut, creating 6-mm-long × 3-mm-diameter cylinders. At each test period, 4 specimens from Gc and all 16 specimens from the appropriate experimental group were submitted to compressive strength testing (1 mm/min). The groups demonstrated the following mean (SD) values of compressive strength Gc, 174.41 (56.10) MPa; G7d, 161.29 (39.10) MPa; G14d, 130.27 (57.53) MPa; G30d, 167.88 (34.24) MPa; and G90d, 129.62 (31.46) MPa. Statistically significant differences among the groups were found (P = 0.007; analysis of variance and Tukey test, α = 5%), with a significant difference between Gc and both G14d and G90d (P 0.05) among the mean compressive strength values of the experimental groups (7, 14, 30, and 90 days). The results indicated that the use of Ca(OH)2 as an intracanal medication for periods of 14 and 90 days reduced the fracture resistance of root dentin.The aim of this study was to evaluate the influence of the geometry of the screwdriver-screw connection on the reverse torque of UCLA screws after repeated cycles of tightening and loosening in an implant-supported prosthesis. Thirty sets of external hex titanium implants, UCLA abutments, and UCLA abutment screws were divided into 3 experimental groups (n = 10). In the square group, the implant and UCLA abutment system were mounted in an upright position using a screw with a square screwdriver-screw connection. In the hexagonal group, the implant and UCLA abutment system were mounted in an upright position using a screw with a hexagonal screwdriver-screw connection. In the hexalobular group, the implant and UCLA abutment system were mounted at 70° using a dynamic UCLA abutment and screw with a hexalobular screwdriver-screw connection. Ten alternating torque-reverse torque cycles were applied to each screw using a screwdriver fixed at the end of a digital torque meter. The screws with a square connection resulted in less loss of reverse torque than the other types. Screws with a hexagonal connection showed a statistically significant loss of torque initially but remained constant for the remaining cycles. For the screws with a hexalobular connection, the loss of torque was greater, and substantial deformation of the plastic in the microstructure was noted. The screwdriver-screw connection geometry had a direct influence on the reverse torque of UCLA screws, and the initial reverse torque of the abutment screws with a square connection was greater than that of the hexagonal and hexalobular designs.The finding of medial arterial calcification (MAC) on cone beam computed tomographic scans is more common than many clinicians realize. Medial arterial calcification is a specific pattern of vascular calcification that has been associated with diabetes mellitus. When MAC is identified on a scan, the clinician must refer the patient for evaluation of cardiovascular accident risk and for serologic evaluation to detect undiagnosed type 2 diabetes mellitus. This case report describes a patient with undiagnosed type 2 diabetes mellitus that was later confirmed by hemoglobin A1c levels after incidental detection of MAC on cone beam computed tomography. The article also reviews the literature on MAC and its relationship with diabetes and discusses radiographic features of MAC that are often unrecognized by clinicians.The endocrown is a ceramic restoration that combines a core and a crown into a single structure. This restoration can be useful for endodontically treated teeth, for which traditional crown preparation can be difficult. Although most of these restorations are fabricated using single-visit computer-aided design/computer-aided manufacturing technology, they can also be fabricated by a laboratory using traditional polyvinyl siloxane impressions. This article will review the concept of endocrowns and describe 3 clinical situations in which an endocrown was utilized for the restoration of a compromised endodontically treated tooth.The aim of this study was to evaluate the effects of different polishing techniques on the surface roughness and gloss of various composites. A total of 360 composite cylinders (6 mm in diameter and 2 mm in thickness) were made using a silicone matrix and 1 of the following 6 restorative materials (n = 60) Admira Fusion, GrandioSO, Filtek Supreme, Filtek Z250, TPH Spectra ST, and Herculite Classic. The composite specimens were cured and then immersed in water for 24 hours. The baseline roughness was standardized with 600-grit silicon carbide paper used in a polishing device for 30 seconds. The specimens were divided into 6 subgroups (n = 10) according to the polishing technique abrasive discs (Sof-Lex); abrasive discs (Sof-Lex) and diamond paste (Diamond Excel); abrasive rubber point (Dimanto); silicon carbide polishing brush (OptiShine); rubber spiral wheels (Sof-Lex Spiral Wheels - Diamond Polishing System); or sequential application of polishing pastes (Diamond ACI and ACII). After polishing was completed, the surface roughness and gloss were measured, and the data underwent 2-way analysis of variance and the Tukey test (P less then 0.05). Statistically significant differences were observed for roughness (P less then 0.001) and gloss (P less then 0.001) for both factors analyzed (composite material and polishing technique). Admira Fusion exhibited the highest roughness and lowest gloss values of all of the composites, and Filtek Supreme exhibited the lowest roughness and highest gloss values. Sof-Lex Spiral Wheels and OptiShine polishing brush exhibited lower roughness and higher gloss than the other polishing techniques. The effects of different polishing techniques were material dependent, but all systems tested provided clinically acceptable results. The use of a single polishing technique for all types of composite materials might result in undesirable clinical outcomes.This study aimed to evaluate the accuracy of smartphones for digitizing, sharing, and viewing conventional radiographic images. Eighty conventional radiographs of 40 teeth with metallic mesio-occlusodistal restorations (40 radiographs showing perfectly adapted restorations and 40 showing restorations with a 0.4-mm proximal gap) were digitized using a smartphone and then evaluated using 2 viewing methods a light box (LB) and a smartphone screen (SS). Three examiners assessed all radiographs for the presence of marginal gaps using a dichotomous yes/no scale. To analyze examiner reproducibility, 10% of the samples was reassessed. Smad inhibition The sensitivity, specificity, and overall accuracy were calculated for each examiner and viewing method. The McNemar test was used to compare examiners' diagnoses based on the 2 viewing methods. The level of statistical significance was set at P 0.05). The results achieved were promising, suggesting that the smartphone can be presented as a new aid for radiographic evaluation (LB accuracy, 0.
