The Impact of Fissure Depth and Enamel Conditioning Protocols on Glass-ionomer and Resin-based Fissure Sealant Penetration
(Quintessence Publishing Co Inc, Hanover Park, 2011)
Purpose: To evaluate the effect that fissure depth and enamel conditioning protocols have on penetration abilities of resin-based and glass-ionomer fissure sealants. Materials and Methods: Fifty extracted human molars were ...
The difference in miR-21 expression levels between invasive and non-invasive breast cancers emphasizes its role in breast cancer invasion
(Humana Press Inc, Totowa, 2014)
MicroRNA-21 (miR-21) overexpression is characteristic for various types of tumors, but it is still unknown whether its expression levels differ between invasive and non-invasive breast carcinomas. The main goal of the study ...
Application of Replica Technique and SEM in Accuracy Measurement of Ceramic Crowns
(Versita, Warsaw, 2012)
The paper presents a comparative study of the measuring values of the marginal gap related to the ceramic crowns made by dental CAD/CAM system using the replica technique and SEM. The study was conducted using three ...
In Vitro Radiographic Detection of Cement Overhangs on Cement-Retained Implant Restorations
(Quintessence Publishing Co Inc, Hanover Park, 2013)

Correlation between different genotypes of human cytomegalovirus and Epstein-Barr virus and peri-implant tissue status
(Wiley, Hoboken, 2011)
Background: The purpose of this study was to estimate the prevalence of different genotypes of human cytomegalovirus (HCMV) and Epstein-Barr virus (EBV) in peri-implantitis and mucositis sites, and to evaluate the correlation ...
Quantitative micro-Raman assessment of dentine demineralization, adhesive penetration, and degree of conversion of three dentine bonding systems
(Wiley, Hoboken, 2008)
Unreacted monomers in adhesive systems may cause a reduction in material properties, an increase in the long-term instability of the restoration, and pulpal irritation. The degree of dentine demineralization, adhesive ...
Microtensile vs Microshear Bond Strength of All-in-One Adhesives to Unground Enamel
(Quintessence Publishing Co Inc, Hanover Park, 2010)
Purpose To determine the bond strength to unground enamel of all in one adhesives in comparison with an etch and rinse system and to compare the reliability of microtensile and microshear methods in providing such measurements ...

Implant stability in posterior maxilla: bone-condensing versus bone-drilling: a clinical study
(Mosby-Elsevier, New York, 2011)
Objective. The aim of this clinical trial was to compare primary and secondary stability of implants placed by bone condensing versus the standard drilling technique in the posterior edentulous maxilla. Study design. ...
Comparison of clonidine and epinephrine in lidocaine anaesthesia for lower third molar surgery
(Churchill Livingstone, Edinburgh, 2005)
The admixture of clonidine or epinephrine to lidocaine for inferior alveolar nerve block was studied with regard to onset, duration, intensity of anaesthesia, postoperative analgesia, systolic blood pressure (SBP), diastolic ...
