Ridge preservation protocols reduce crestal remodeling after tooth extraction. Limited evidence supports the potential of different grafting materials to preserve the alveolar ridge. There is limited evidence to indicate advantage of bone replacement grafting in combination with platelet rich plasma (PRP), compared to grafting alone. A combination of recombinant human platelet derived growth factor (rhPDGF-BB) with beta tricalcium phosphate (ß-TCP) has recently been approved to aid wound healing. Aim: To evaluate early healing of grafted and non-grafted extraction sockets in the es-thetic zone, with or without PRP and rhPDGF-BB. Materials and Methods: Population consisted of 41 healthy adult patients whose …
In Vitro Wear Of Nine Cements Against Enamel, Mohamad Kyson
In Vitro Wear Of Nine Cements Against Enamel, Mohamad Kyson
All ETDs from UAB
The objective of this study was to measure and compare in vitro wear resistance of nine cements against human enamel cusps in glycerol media using UAB second generation wear machine (hit and slide). Six cements were dual cured polymer-based cements; total-etch: Variolink II (Ivoclar Vivadent), self-etch: Multilink Automix (Ivoclar Vivadent) and self-adhesives: Maxcem Elite (Kerr), RelyX Unicem 2 (3m ESPE), PANAVIA SA (Kuraray) and G-CEM LinkAce (GC America). Three cements were water-based chemical cured cements; Zinc-phosphate: Harvard Cement (Harvard) and resin modified glass ionomers cements: RelyX Luting Plus (3M ESPE) and GC FujiCEM 2 (GC America). Samples were scanned after …
Regional In Vitro Retention Of Fiber Posts, Shayma Kyson
Regional In Vitro Retention Of Fiber Posts, Shayma Kyson
All ETDs from UAB
The overall objective of this in vitro study was to determine the biomechanical retention along fiber post interfaces to root canal dentin of four different fiber posts systems combined with five different resin cements (total-etch, self-etch and self adhesive systems) tested within different regions of dentin (cervical, middle and apical levels) and the core material alone. Scanning electron microscopy (SEMs) was used to evaluate the failure characteristics of the systems for root canal dentin and core material interfaces. Roots of freshly extracted first mandibular premolars, without caries, cracks or defects were selected. Radiographs made from mesiodistal and buccolingual directions were …
