The influence of harvest period and drying method of Salvia officinalis L. leaves on the content of essential oils, polyphenols and antioxidant properties was investigated. Sage leaves were collected twice during plant blossoming (in June and July) and dried traditionally in natural conditions and at 35 °C. Antioxidant activity was assayed in methanol-acetone extracts and infusions of dried leaves with the use of free radical scavenging activity (DPPH) and ferric reducing antioxidant power (FRAP) technique. Total phenolic content in extracts as well as in infusions was determined by the means of Folin–Ciocalteu method. Based on the LC/MS analysis, the polyphenol compounds present in both extracts and in infusions were identified. The extracts contained more polyphenols and were characterized by higher antioxidant activity than infusions. In the extracts significant amount of ferulic acid was found, which was influenced both by the harvest period and drying method. The amount of ferulic acid found in extracts obtained from the June leaves dried traditionally was three times lower (6.185 μg/g DW) than in extracts from July leaves dried in the same conditions. Harvest period had a significant effect on the essential oils’ content, leaves collected in July contained 15% more oils than those collected in June.

Purpose: The purpose of the current study was to compare the effect of different surface treatments on the light transmission and adhesion of two types of posts. Materials and Methods: Two groups of glass Fiber post specimens (Glassix) Conventional glass fiber post and (Glassix plus) Translucent glass fiber posts were prepared 10 mm length and 1.5 mm diameter (n = 40). The groups were classified into four sub groups (n=5): Group 1: Did Not receive any treatment; Group 2: treated with hydrofluoric acid (HF) 9.6%. Group 3: treated with 110 μm Al 2 O 3 ; Group 4: exposed to (Er-Cr:ySGG) laser. The light transmittance of the specimens was compared using a spectrophotometer and bond strength measured for each post at (middle-apical-coronal) using universal testing machine. Results: there was no significant effect of surface treatments on light transmittance of posts (P > 0.001) control group had the highest values while the HF group had the lowest value. Surfaces treatment had significant effects on bond strength of posts (P < 0.001) translucent post had bond strength higher than conventional post. Conclusion: Application of surface treatments had no significantly effect on the translucence property of fiber posts but significatly Affected bond strength.

“…Unlike previous resin cement, SARC is simple, time-saving, and has the advantage of fewer clinical steps required for the bonding procedure along with better control of moisture in the root canal space because no smear layer removal or pretreatment of dentin is required [ 30 , 31 , 32 ]. Functional acidic monomer in self-adhesive resin cement helps in bonding by having a strong affinity towards calcium in hydroxyapatite [ 29 , 33 , 34 ]. Studies have proven that phosphoric acid ester functional monomer 10-MDP in newer adhesives forms nano-layer at the adhesive-dentin interface that imparts better clinical longevity and integrity of the bond [ 35 , 36 , 37 ].…”

This study aimed to evaluate the effectiveness of conventional and sonic activation techniques on push-out bond strength of fiber post cemented with two different monomers containing self-adhesive resin cement (SARC). Four groups (n = 19 each) were made based on the type of SARC (Rely X U200 and Panavia SA) and technique (conventional and sonic activation). After placing the fiber post, each root was sectioned into 2 mm coronal, middle, and apical portions, and a push-out bond strength test was performed using a universal testing machine. The least push-out bond strength (13.0 ± 0.9 MPa) was found in Rely X U200 conventional technique and highest with Panavia SA sonic activation technique (15.4 ± 0.9 MPa). A significant difference was found in push-out bond strength at coronal (p = 0.002), middle (p = 0.002), and apical (p = 0.001) root sections using Rely X U200 cement with sonic activation as compared to the conventional technique. However, no difference (p > 0.05) was noticed between conventional and sonic activation techniques in Panavia SA cement at any root level. Sonic activation can be used as an adjunct with a manual technique to increase bond strength. However, it was noted that 10-MDP monomer containing SARC performed well regardless of techniques.
