Trevilatto

School of Dentistry Faculty Research and Publications

Background

Apoptosis is a programme of cell death which does not induce an inflammatory response. Recent previous research has suggested a correlation between temporomandibular internal derangement and apoptosis. Fas ligand (FasL) is an apoptosis‐inducing factor, known to trigger apoptosis through distinct signal pathways. This study aims to examine, by immunohistochemistry, the expression of FasL in temporomandibular joint (TMJ) articular discs of patients with anterior disc displacement with reduction (ADDwR) and without reduction (ADDwoR) in patients with and without osteoarthrosis (OA).

Methods

Forty‐two (n = 42) TMJ articular discs were divided into two cut‐offs: (i) 8 control, 17 ADDwR, 17 …

School of Dentistry Faculty Research and Publications

This study demonstrates that it is sometimes possible to replicate patterns of human teeth in pig skin and determine scientifically that a given injury pattern (bite mark) correlates with the dentitions of a very small proportion of a population dataset, e.g., 5 percent or even 1 percent. The authors recommend building on the template of this research with a sufficiently large database of samples that reflects the diverse world population. They also envision the development of a sophisticated imaging software application that enables forensic examiners to insert parameters for measurement, as well as additional methods of applying force to produce …

Management Of Dental Extraction In A Female Patient With Fanconi Anemia, Andre Peisker, Gregor F. Raschke, Arndt Guentsch, Korosh Roshanghias, Stefan Schultze-Mosgau

School of Dentistry Faculty Research and Publications

Oral surgery in patients with bleeding disorders is associated with a high risk of bleeding during and after surgery. This article is aimed to present the case of an eight-year-old girl suffering from severe Fanconi anemia with pancytopenia who underwent a dental extraction. The hemostatic effect of local administration of tranexamic acid in combination with a primary suture seems to be extremely helpful in order to reduce the necessity of blood products and the risk of postoperative bleeding.
