BACKGROUND The periodontal disease is a complex chronic progressive inflammatory and destructive process of the tooth attachment apparatus: gingiva, alveolar bone, desmodontium, cementum. Systemic osteoporosis has a potential influence on both the periodontal and gingival inflammation indices, on the gingival recession (GR) and teeth mobility. The aim of this study was to investigate the possib...

[1] Base flow recession information is helpful for regional estimation of low-flow characteristics. However, analyses that exploit such information generally require a continuous record of streamflow at the estimation site to characterize base flow recession. Here we propose a simple method for characterizing base flow recession at low-flow partial record stream gauges (i.e., sites with very fe...

Using the 2006 and 2010 Health and Retirement Study, we explore how the recent recession impacted the wealth holding and retirement plans of older households in the United States. Of particular interest to us is whether the impact on household asset ownership, asset wealth and household retirement behavior varied with the nativity of the household and its standing in the wealth distribution pri...

Gingival recession is defined as “Displacement of soft tissue margin apical to the cemento-enamel junction”. Gingival recessions require treatment for many reasons – impaired aesthetic appearance, root sensitivity, cervical caries or abrasion. Presence of gingival recession and gingival inflammation in areas with a lack or narrow band of attached gingiva is identified as a mucogingival problem....

Frenal attachments are thin folds of mucous membrane with enclosed muscle fibers that attach the lips to the alveolar mucosa and underlying periosteum. Most often, during the oral examination of the patient the dentist gives very little importance to the frenum. The frena may jeopardize the gingival health when they are attached too closely to the gingival margin, either due to interference in ...

PURPOSE Classic teaching suggests that surgery for intermittent exotropia should be based on distance/near differences. True divergence excess exotropia should be treated with symmetric lateral rectus recession. The aim of this study was to investigate the effect of large bilateral lateral rectus (LR) recession in large-angle intermittent exotropia. METHODS Thirty-three consecutive patients w...

Gingival recession is common in many patients, and generally is associated with periodontal disease, inadequate toothbrushing, and repeated periodontal instrumentation, among other etiologies. Gingival recession as a consequence of regular toothbrushing has been reported, and can be observed even in young populations with well-established habits of oral hygiene. Gingival recession also is assoc...

An enthalpy-balance fuel-grain regression model is presented. The regression model, based on the longitudinally averaged fuel recession rates, is shown to accurately predict the chamber pressure, thrust and specific impulse performance of small and medium scale hybrid rocket motors. The key to the model predictions is the longitudinal enthalpy balance between the fuel grain heat of ablation and...

Gingival recession is the most common mucogingival deformity and should be treated at its earliest detection. Exposed root surfaces are more likely to develop root sensitivity and root caries and pose esthetic problems. Among various procedures, laterally positioned pedicle graft (LPG) is widely used successfully to cover Miller’s class-I and Class-II recession defects. The main advantages of t...

Young People and the Great Recession This article reviews the effects of the Great Recession on youth labour markets. We argue that young people aged 16-24 have suffered disproportionately during the recession. Using the USA and UK as case studies, we analyse youth unemployment using microdata. We argue that there is convincing evidence that the effects of unemployment when young impose costs o...
