statement of the problem: recently allogenic mesenchymal stem cells are proposed to have multipotential progenitor cell capabilities to differentiate into cementoblasts, osteoblasts, and periodontal ligament fibroblasts. purpose: the aim of the present study was to compare the efficacy of human umbilical stem cells cultured on polylactic acid (pla), polyglycolic acid (pga) membrane with pla/pga...

PURPOSE To compare postoperative exodrift of the first unilateral lateral rectus (ULR) muscle recession with the exodrift of the second contralateral ULR muscle recession in patients with recurrent small-angle exotropia (XT). METHODS We evaluated the results of a second ULR muscle recession in 19 patients with recurrent XT with deviation angles under 25 prism diopter (PD), following a first p...

AIMS To compare the postoperative surgical outcomes and the changes in deviation achieved per millimetre of recession in patients treated by graded unilateral medial rectus (UMR) or bilateral medial rectus (BMR) recession for small to large angle esotropia with a minimum follow-up of 6 months. METHODS In a retrospective, consecutive and interventional case series, 102 patients underwent UMR r...

The aim of this study is examine trends in breast and colorectal cancer screening in the U.S. by race, healthcare coverage, and socio-economic status (SES) before the Great Recession (2003-2005), during the recession (2007-2009), and post-recession/Affordable Care Act (ACA) period (2010 - 2012). Data on a representative sample of U.S. adults was obtained from the Behavioral Risk Factor Surveill...

PURPOSE To suggest a surgical normogram for lateral rectus recession in exotropia associated with unilateral or bilateral superior oblique muscle palsy (SOP). METHODS We retrospectively reviewed the charts of 71 patients with exotropia who were successfully corrected over one year. Each patient had undergone unilateral or bilateral rectus recession associated with uni- or bilateral inferior o...

Gingival recession is the displacement of the gingival margin apical to the cemento-enamel junction resulting in the exposure of root surface which puts the patient at risk for dentine hypersensitivity, root caries, abrasion/erosion of roots etc. The etiology can be inflammatory periodontal disease, developmental anatomic abnormalities (aberrant frenal attachment, thin bony plate), toothbrush i...

Aims: to determine the prevalence of gingival recession and dentine hypersensitivity among the study population, and evaluate the distribution of dentine hypersensitivity among various types of teeth in mild, moderate and severe degrees of gingival recession. Relationship between the severity of gingival recession and dentine hypersensitivity was also evaluated. Materials and Methods: Clinical ...

OBJECTIVE During the Great Recession in America, African-Americans opted to forgo healthcare more than other racial/ethnic groups. It is not understood whether disparities in forgone care returned to pre-recession levels. Understanding healthcare utilization patterns is important for informing subsequent efforts to decrease healthcare disparities. Therefore, we examined changes in racial dispar...

background: gingival recession is the most common and undesirable condition of the gingiva. the aim of study was to investigate the aetiology and severity of gingival recession in a greek adult population sample.     methods: the study was performed on 165 males and 179 females, 18-68 years old who sought dental treatment in a private dental practice and showed gingival recession. all subjects ...

Hydrograph recession constants are required in rainfall-runoff models, base flow augmentation studies, geohydrologic investigations and in regional low-flow studies. The recession portion of a streamflow hydrograph is shown to be either an autoregressive process or an integrated moving average process, depending upon the structure of the assumed model errors. Six different estimators of the bas...
