Enhanced Human Periodontal Ligament Stem Cell Viability And Osteogenic Differentiation On Two Implant Materials: An Experimental In Vitro Study, Engy Adel Ahmed Farag, Sara Fikry Dr, Shereen N. Raafat

Dentistry

Background: Surface roughness of dental implants impacts the survival of adult periodontal stem cells and rate of differentiation. This research was conducted to test how human periodontal ligament stem cells behaved on yttria stabilized tetragonal zirconia polycrystals and polyetheretherketone (PEEK) discs with different surface topographies.

Methods: Discs roughening was prepared by sandblasting. Stem cells were cultivated on zirconia discs with a polished surface, polyetheretherketone (PEEK) discs with a polished surface, sandblasted zirconia discs and sandblasted polyetheretherketone (PEEK) discs. Cells viability was assessed after 24, 48, 72 hours. Scanning electron microscopy was used to examine the adherence and attachment of cells. …

Effect Of Different Polishing Systems On Surface Roughness And Color Stability Of Lithium Disilicate Ceramics, Mahmoud Al Ankily, Fatma Makkeyah

Dentistry

Objective: This study aimed to investigate the effect of two polishing systems on the surface roughness and color stability of lithium disilicate ceramic. Materials and Methods: Forty disc-shaped lithium disilicate samples were constructed and cemented into a cavity prepared onto the labial surface of freshly extracted bovine teeth; The samples were divided into four groups (10 samples per group); C: Control, SS: Scaling only, SE: Scaling followed by polishing using Eve Diapro lithium disilicate polishers, SD: Scaling followed by polishing using Diatech ShapeGuard ceramic polishing plus kit. The surface roughness was measured before scaling, after scaling and finally after the …

An In Vitro Evaluation Of Surface Roughness, Color Stability And Bacterial Accumulation Of Lithium Disilicate Ceramic After Prophylactic Periodontal Treatment, Fatma Makkeyah, Tarek Salah Morsi, Marwa Mohamed Wahsh, Amr Saleh El-Etreby

Dentistry

Objective: To evaluate the effect of scaling procedures using different ultrasonic tips on the surface roughness, color stability and bacterial accumulation of lithium disilicate ceramic. Material and Methods: Scaling procedure was carried out using ultrasonic scaler (Satalec, Acteon, North America) with stainless-steel tip (US), titanium tip (UT) and plastic tip (UP), on disc shaped lithium disilicate samples cemented into a cavity prepared onto the labial surface of freshly extracted bovine teeth (10 samples per group). The samples were stored in coffee solution in an incubator at 37°C for 12 days, which is equivalent to 1 year of coffee consumption. The …

Assessment Of Physical Properties Of A Zno/E ~Sealer Modified By Adding Moringa Oleifera: An Experimental In-Vitro Study, Engy M. Kataia, `Maram E. Khallaf, Nada Omar, Yousra Aly, Nancy Elshafei

Dentistry

Aim: In an attempt to move toward exploration of the antibacterial properties of herbal products, this study evaluated the effect of how the addition of Moringa would affect the physical properties of the commercial Endofil sealer. Materials and Methods: An experimental in vitro study was performed using three experimental sealers. There were four groups in this study: Group A (ZnO/E sealer alone), Group B (ZnO/E and Moringa root), Group C (ZnO/E and Moringa leaf), and Group D (ZnO/E and Moringa leaf extract liquid). Measurements were carried out according to International Organization for Standardization (ISO) standardization 6876:2012. Moringa oleifera was added …

Effect Of Different Scaling Methods And Materials On The Enamel Surface Topography: An In Vitro Sem Study, Mahmoud Al Ankily, Fatma Makkeyah, Mohamed Shamel, Mahmoud Bakr

Dentistry

Aims and Objectives: Scaling is important for maintenance of gingival and periodontal conditions. These procedures have a harmful effect on the dental hard tissues. The aim of this study was to investigate the effects of hand and ultrasonic instruments made of stainless and titanium on the surface properties of enamel. Materials and Methods: Forty extracted premolars were used in this in vitro study and were randomly divided into four groups (n = 10). Group I received ultrasonic scaling with stainless steel tip, group II received ultrasonic scaling with titanium tip, group III hand scaling with stainless steel tip, and group …
