Purpose: Sealants are an effective method of prevention and treatment for early caries lesions. This study analyzed the 1-year clinical performance of resin-based and ionomeric sealants applied to permanent teeth under different humidity conditions.
Methods: The investigation was a triple-blind randomized clinical trial (RCT) with a four arms split-mouth design, divided according to the sealant protocol: (1) Resin-based sealant applied with rubber dam isolation, (2) Resin-based sealant applied with cotton rolls isolation, (3) Ionomeric sealant applied with rubber dam isolation and (4) Ionomeric sealant applied with cotton rolls isolation. Fifty-eight patients started the study (232 teeth), and 47 (188 teeth) remained until the 1-year recall. The modified USPHS criteria were used in the analyzes to investigate surface texture, retention and the presence of secondary caries lesions around the sealants; in the following periods: baseline, after 3, 6, 9, and 12 months by two calibrated examiners. Data were analyzed by the Mann-Whitney and Friedman tests.
Results: There was no difference between the types of sealants (p > 0.05). The type of humidity control influenced the superficial texture (p = 0.0012) and the retention of sealants (p = 0.0023). The sealant displacement was greater under cotton rolls isolation. Only one active caries lesion in enamel was found in the 9th month.
Conclusion: It may be concluded that sealants effectively prevented caries, even when they were partially or totally lost, regardless of the material. The rubber dam isolation with a rubber dam promoted lower surface roughness and improved the retention rates. International Clinical Trials Registry Platform: #1111-1215-2832 (07/26/2018).

Objective: The aim of the study was to evaluate the hemostatic efficacy of the fibrin sealant patch (TachoSil) after loop electrosurgical excision (LEEP) and its influence on other complications and quality of life (QoL).
Materials And Methods: This single-blind, prospective, randomized study involved patients undergoing LEEP with or without TachoSil (1:1) between August 2014 and August 2015 in Asan Medical Center, Korea. Primary outcome measures were bleeding duration and the frequency of additional treatment owing to vaginal bleeding within 2 weeks after LEEP.

Objective: To evaluate the influence of in situ acid erosion on the structural and optical properties of nanoparticulate bisacrylic resin with different surface treatments, evaluating surface roughness (Ra), knoop microhardness (KHN), color change (ΔE, ΔL, ΔC, ΔH), contrast (CR) and translucency (TP).
Methods: Eighty specimens were made (n = 10 per group) and the following surface treatments were applied: U-unpolished; A-polishing with Astropol rubber tips (Ivoclar); S-Biscover LV surface sealant (Bisco) and S-Palaseal surface sealant (kulzer). For the in situ experiment, 10 volunteers wore an intraoral appliance containing eight specimens (two specimens per experimental group), with only one specimen from each experimental group being subjected to the acid process.

The current research is devoted to integrating naturally renewable cardanol derivatives into one-component silyl-terminated-polyether-based prepolymer systems to improve climatic resistance and obtain materials with versatile mechanical properties that could be significant to various sectors of the economy. Various cardanol-type products are used in industries that require high climatic resistance, and thus combining cardanol with commercially available silyl-terminated polyether prepolymers would improve its material climatic resistance, maintaining its market and application value as well as improving material sustainability. The results obtained in this work show that depending on how the cardanol prepolymer Ultra Lite 513 is modified, it is possible to increase the elasticity (670%) or tensile strength (104%) of the material as well as significantly increase the climatic resistance of the material, thus improving the quality and sustainability of the adhesive compared to existing silyl-terminated-prepolymer-based adhesives on the market.
