Accelerated sea level rise (SLR) in the twenty-first century will result in unprecedented coastal recession, threatening billions of dollars worth of coastal developments and infrastructure. Therefore, we cannot continue to depend on the highly uncertain coastal recession estimates obtained via the simple, deterministic method (Bruun rule) that has been widely used over the last 50 years. Furth...
Statement of Problem: Treatment of gingival recession defect and covering denuded root surfaces is one of the goals in periodontal therapy and several surgical techniques have been suggested in this field.Purpose: The aim of this study was to perform a comparison on coronaliy repositioned flap procedure with and without the use of ethylenediaminoteraacetic acid (EDTA. 24%, pH=7) in the treatmen...
It has been suggested that proclination of the lower incisors results in gingival recession. Proclination is, however, a valuable alternative to extraction especially when considering facial aesthetics in adult patients. The aim of this study was to evaluate the association between the extent of labial movement of the lower incisors and the prevalence and severity of gingival recession in ortho...
PURPOSE The hang-back suture technique has been advocated to decrease the risk of scleral perforation during strabismus surgery. In this study, we evaluated the muscle insertion site in rabbits 4 weeks after a hang-back recession was performed. METHODS Twenty-five eyes of 13 rabbits underwent hang-back recessions of between 5 and 8 mm of the superior rectus muscle. Four weeks later, the attac...
[1] Recession flows in a basin are controlled by the temporal evolution of its active drainage network (ADN). The geomorphological recession flow model (GRFM) assumes that both the rate of flow generation per unit ADN length (q) and the speed at which ADN heads move downstream (c) remain constant during a recession event. Thereby, it connects the power law exponent of –dQ/dt versus Q (discharge...
BACKGROUND The surgical techniques used to treat gingival recession have changed considerably in the last 50 years. The envelope technique described nearly 20 years ago still offers an excellent alternative for the problem of recession. The purpose of this retrospective study is to show the results of 115 recession sites treated in 50 patients using the envelope technique. METHODS One hundred...
BACKGROUND There have been passing references in history that excessive occlusal forces might be a causative factor in gingival recession. The purpose of the present cross-sectional study was to explore the role of trauma from occlusion on the development of gingival recession. METHODS Three hundred patients reporting to the department of Periodontics were screened for the presence of gingiva...
I propose a framework for the assessment of current business conditions using a factor-augmented autoregressive probit model where the dependent variable is the state of the economy as defined by the NBER. Results show that latent common factors estimated by principal components analysis from a large number of macroeconomic series have important predictive power for NBER recession dates. The mo...
This study evaluates the long-term cost of unemployment in Finland by focusing on the deep recession period of the early 1990s. The number of plant closures increased sharply during the recession and the unemployment rate rose over 13 percentage points. In the analysis, prime working age men who face unemployment due to plant closure are matched on those who remained employed during the recessi...
