Comparison Of Dna Extracted From Pediatric Saliva, Gingival Crevicular Fluid And Site-Specific Biofilm Samples, Jason Emett, Roxanne David, Jaydene Mcdaniel, Steven Mcdaniel, Karl Kingsley

Dental Medicine Faculty Publications

(1) Introduction: Due to the non-invasive nature of saliva, many methods have been used to isolate and collect DNA from saliva samples for microbial screening. Many oral microbes also inhabit the oral biofilm, which may represent significantly different microbial constituents that may contribute to oral health and disease, including caries and periodontal disorders. Moreover, the biofilm may vary within the same patient at different sites. Few studies have evaluated the comparison between DNA isolated from saliva and DNA from site-specific biofilm, with virtually no studies addressing this analysis among pediatric patients. (2) Methods: An existing repository of paper point derived …

Three-Dimensional Bio-Printing And Bone Tissue Engineering: Technical Innovations And Potential Applications In Maxillofacial Reconstructive Surgery, Muhja Salah, Lobat Tayebi, Keyvan Moharamzadeh, Farhad B. Naini

School of Dentistry Faculty Research and Publications

Background

Bone grafting has been considered the gold standard for hard tissue reconstructive surgery and is widely used for large mandibular defect reconstruction. However, the midface encompasses delicate structures that are surrounded by a complex bone architecture, which makes bone grafting using traditional methods very challenging. Three-dimensional (3D) bioprinting is a developing technology that is derived from the evolution of additive manufacturing. It enables precise development of a scaffold from different available biomaterials that mimic the shape, size, and dimension of a defect without relying only on the surgeon’s skills and capabilities, and subsequently, may enhance surgical outcomes and, in …
