Future Dental Journal

Aim of the study: Is to compare the effects of smoking T-cigs and vaping E-cigs on clinical periodontal parameters in patients.Materials and Methods: It consisted of a clinical examination of a total of 60 individuals aged between 29 and 39 years. They responded to a questionnaire about their smoking history, and they were divided into 2 groups as E-cig vapers and T-cig smokers. Full-mouth plaque index (PI),bleeding on probing (BOP),clinical attachment loss (AL),and probing depth (PD) were measured at six sites per tooth on all maxillary and mandibular teeth except third molars. Results: T-cigarette had significantly higher probing depth, …

Influence Of Etching Methods On The Shear Bond Strength Of A Universal Adhesive System To Sound And Artificial Caries-Affected Dentin, Omnia M. Sami, Essam A. Naguib, Rasha H. Afifi, Shaymaa M. Nagi

Future Dental Journal

Abstract:

This study tested the effect of different etching methods on the bond strength of a universal adhesive system to caries-affected (CAD)and sound dentin. Methods: forty premolars were wet grinded to expose flat occlusal midcoronal dentin. Specimens were equally divided according to the substrate; sound and (CAD) by exposing to pH-cycling for 14 days. Each dentin substrate was bonded with Single Bond^TM universal adhesive applied either after no etching or etching of dentin, then resin composite was built up. Specimens were tested for shear bond strength (SBS). The data was analyzed by two-ways ANOVA. Results: Single Bond^TM universal …
