Self-ligating vs. conventional ligating orthodontic bracket systems (smile aesthetics perspective) : data from randomised clinical trials

Alarabi, Abdulghani Mustafa S. January 2018 (has links)
<b>Introduction</b>: Today one of the primary goals of any kind of dental treatment is the achievement of balanced smile aesthetics, as patients increasingly attend dental clinics to improve their appearance. The main aim of the present study was to assess and compare the smile aesthetics created by the use of two orthodontic bracket systems (self-ligating vs. conventional ligating) as a part of analysing secondary outcomes of two randomised clinical trials comparing between these two systems. <b>Methodology</b>: The assessment of smile aesthetics was done by analysing and scoring post-orthodontic treatment 125 frontal smile photographs subjectively and objectively. The subjective evaluation was performed by 20 dental professionals and 20 laypeople, while the objective assessment was done by one principal examiner using a group of smile aesthetics parameters. <b>Statistical analysis</b>: Multiple regression statistical analyses were performed to test the association between subjective and objective assessment of smile aesthetics in order to find the significant smile aesthetics predictors and assess the effect of the bracket type (self-ligating vs conventional) on the resulting smile aesthetics. <b>Results</b>: The finding from this research shows that the bracket type was not an important smile aesthetics factor in all the statistical models, although there are other important smile aesthetics factors as there was a significant correlation between the subjective and objective assessment of smile aesthetics parameters (Pearson’s correlation coefficients “r” > 0.50). <b>Conclusion</b>: There is insufficient evidence to reject the null hypotheses of no significant difference in the smile aesthetics created by the two orthodontic bracket systems. An Orthodontic Smile Aesthetics Rating (OSAR) tool has been developed.

Esthetics and Smile Characteristics Evaluated by Laypersons: A comparison of Canadian and US data

McLeod, Catherine E. 25 June 2010 (has links)
Objective: To collect data regarding Canadian laypersons perceptions of smile esthetics and compare these data to US data in order to evaluate cultural differences. Methods: Using Adobe® Photoshop® 7, a digital image of a posed smile of a sexually ambiguous lower face was prepared so that hard and soft tissue could be manipulated to alter Buccal Corridor (BC), Gingival display (GD), Occlusal Cant (OC), Maxillary Midline to Face Discrepancy (MMFD) and Lateral Central Gingival Discrepancy (LCGD). Adult Canadian laypersons (n=103) completed an interactive computer-based survey of 29 randomized images to compare smile preferences for these variable. The custom survey was developed to display fluid, continuously appearing modifiable smile variables using MATLAB® R2008 for presentation. These data were compared to previously published data for US laypersons. Statistical inference was determined using Wilcoxon Rank Sum tests. Results: Canadian laypersons were more sensitive in detecting deviations from ideal and had a narrower range of acceptability thresholds for BC, GD, OC, MMFD and LCGD. Ideal esthetic values were significantly different only for BC. Conclusions: It appears cultural differences do exist related to smile characteristics. Clinically significant differences in the preference of the smile characteristics were found between Canadian and US laypersons. Canadian laypersons, on average, were more discriminating to deviations from ideal and had a narrower range of acceptability.

Cell lineage, Zelldifferenzierung und engrailed-Expression in der Mittelinie der Höheren Krebse Orchestia cavimana und Porcellio scaber

Gerberding, Matthias 26 March 1999 (has links)
Embryonen von Höheren Krebsen (Malacostraca) zeigen ein stereotypes Zellteilungsmuster im Ektoderm des Rumpfes, im Verlaufe dessen paarige seitliche Reihen von Zellen und eine unpaare mittlere Reihe von Zellen gebildet werden. Das Muster der seitlichen Zellen ist von Dohle (1970, 1976) und Mitarbeitern geklärt worden. Die vorliegende Arbeit untersucht die cell lineage und Zelldifferenzierung der Mittellinienzellen im Thorax. Diese Zellen sind von besonderem Interesse, weil sie bei Insekten bereits intensiv erforscht wurden. (i) Die DiI Markierungen von Mittellinienzellen von Orchestia cavimana zeigen: Die Bildung der Mittellinie beginnt mit einer Zelle, die sich zweimal in Längsrichtung teilt. Die resultierenden vier Zellen werden mit a0, b0, c0 und d0 bezeichtet. Aus den Zellen a0, b0 und c0 gehen Paare von Gliazellen hervor. Die Tochterzellen von a0 und c0 umhüllen die Kommissuren. Die Zelle d0 ist ein medianer Neuroblast, aus dem mehrere Neurone hervorgehen, unter anderem ein unpaares Neuron im medianen Fasertrakt, interneurone und ein Motoneuron. (ii)BrdU Markierungen von Porcellio scaber zeigen: In den Ganglienanlagen liegt in der Mittellinie je eine Zelle, die größer ist als die benachbarten, schneller proliferiert und deshalb vermutlich ein medianer Neuroblast ist. (iii) Die Expression von engrailed setzt bei Orchestia und Porcellio ein in der Zelle a0 und wird in den zwei Tochterzellen fortgesetzt. Für Orchestia wird gezeigt, daß diese Expression zurückgeht und die Tochterzellen der Zelle d0 de novo mit einer Expression von engrailed beginnen.Aus den Ergebnissen kann abgeleitet werden, daß der gemeinsame Vorfahr von Insekten und Höheren Krebsen eine Mittellinie differenziert, die Vorläufer für Glia der Kommissuren und einen medianen Neuroblasten umfaßt und eine Expression von engrailed in den Tochterzellen des Neuroblasten zeigt. / Embryos of higher crustaceans (Malacostraca) show a highly stereotypic cell division pattern in the ectoderm of the trunk region while forming paired rows of lateral cells and an unpaired median row of midline cells. By using nuclear dyes, the pattern of the lateral cells has been determined by Dohle (1970, 1976) an co-workers. This study addresses the cell lineage and cell differentiation of the midline cells in the thorax. These kind of cells are of particular interest as they have been investigated extensively in insects. (i) The DiI labelling of midline cells in Orchestia cavimana reveals: Formation of the midline starts with a single midline cell that divides twice in longitudinal direction. The resulting four cells are termed a0, b0, c0, and d0. The cells a0, b0, and c0 give rise to pairs of glial cells. The progeny of a0 and c0 enwrap the commissures. The cell d0 is a median neuroblast that gives rise to several neurons, among them an unpaired neuron in the median fibre tract, interneurons and probably a single motoneuron. (ii) BrdU labelling in Porcellio scaber shows: there is a single larger and faster dividing cell in the midline in each segmental ganglion anlage that is a putative median neuroblast. (iii)The expression of engrailed starts in Orchestia and Porcellio the cell a0 and continues in the two daughter cells during segmentation. In Orchestia it can be shown that this expression ceases and progenies of the cell d0 start de novo with the expression of engrailed. From the results can be concluded that the common ancestor of insects and higher crustaceans differentiated an unpaired midline comprising precursors for glial cells enwrapping the commissures and a single median neuroblast whose derivatives express engrailed.

Midline Catheter Use in the Newborn Intensive Care Unit

Romesberg, Tricia L 01 January 2014 (has links)
Ongoing evaluation of current practice and incorporation of evidence based research into guidelines and protocols is a requirement for the provision of high quality, cost efficient care. Despite some literature describing observational data, midline catheters (MCs) are not an appropriate vascular access device for Newborn Intensive Care Unit (NICU) patients due to insufficient high level evidence demonstrating safety and efficacy. In addition, national guidelines for MC use in neonatal and infant patients lacks sufficient information for safe and effective use of MCs. The results of this small, online survey indicate that while some neonatal nurses and Nurse Practitioners report the use of MC use in the NICU, there is a wide range of practice pertaining to MC unit-specific protocols, competencies, success with placement, and clinician agreement of appropriate use for this vascular access device (VAD). Multicenter, randomized control trials are needed to evaluate current MC practice in the NICU, and institutions must incorporates current, evidence based practice into policies, procedures, and guidelines.
