Background: Pit and fissure sealant is a micro-invasive modality for treating deep and retentive pits and fissures to prevent and/or stop occlusal caries. Every effort needs to be done to enhance sealant retention and survival. The aim of this research is to assess the retention rate of giomer S-PRG filler containing pit and fissure sealant applied with or without etching.
Methods: Overall, 52 patients were included in this trial and they were allocated randomly in 2 groups (n = 26). Group 1 (control group) received giomer sealant (Beautisealant, Shofu, Kyoto, Japan) without an etching step, and group 2 (intervention group) received the same but with a separate preparatory etching step before the sealant application. The retention rate of the sealant was assessed over one year at 3 months, 6 months, and 12 months. Intergroup comparison between categorical variables was done using the chi square test, while intragroup comparison was done using Cochran's q test followed by multiple comparisons. Relative risk was used to evaluate the clinical significance. Survival rate was analyzed using Kaplan-meier and Log-rank test.
Results: Intergroup comparison between both techniques revealed statistically significant difference within different follow up periods (P < 0.05). Intragroup comparison within both giomer sealant with etching group and giomer sealant without etching group revealed statistically significant difference between different follow-up periods (P < 0.001). There was 69% less risk for total loss or partial loss of giomer sealant with etching when compared to giomer sealant without etching after 12 months.
Conclusion: An initial preparatory step of etching to the enamel surface is crucial before giomer sealant application to enhance its bonding, increase its retention and promote its survival.

Objectives: To explore the role of newly emerging autoantibodies (AAbs) - peptidyl-arginine deiminase 4 (aPAD4), carbamylated proteins (aCarP), and anti-RA33 (aRA33) - alongside the traditionally assessed rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA), in predicting the response to abatacept (ABT) and its retention rate in rheumatoid arthritis (RA) patients.
Methods: Data from 121 consecutive ABT-treated RA patients were recorded. The RF and ACPA status were retrospectively assessed by reviewing the patients' clinical records.

NaV(PO), based on multi-electron reactions between V/V/V, is a promising cathode material for SIBs. However, its practical application is hampered by the inferior conductivity, large barrier of V/V, and stepwise phase transition. Herein, these issues are addressed by constructing a medium-entropy material (NaVTiAlCrMnNi(PO), ME-NVP) with strong ME─O bond and highly occupied Na2 sites.

With promises for high specific energy, high safety and low cost, the all-solid-state lithium-sulfur battery (ASSLSB) is ideal for next-generation energy storage. However, the poor rate performance and short cycle life caused by the sluggish solid-solid sulfur redox reaction (SSSRR) at the three-phase boundaries remain to be solved. Here we demonstrate a fast SSSRR enabled by lithium thioborophosphate iodide (LBPSI) glass-phase solid electrolytes (GSEs).

Objective: Erdheim-Chester disease (ECD) is a rare non-Langerhans cell histiocytosis that exhibits a wide spectrum of clinical manifestations. The recent identification of activating mutations in the MAPK-ERK pathway in patients with ECD has led to the introduction of targeted therapies. The most commonly used targeted therapies are BRAF- and MEK-inhibitors, which are highly effective but also carry significant toxicity.
