this study is aimed to evaluate the effect of covering exposed root surface by collagen membrane and to compare this method with coronoally advanced flap covering. 26 teeth in 20 patients (12m/8f) with miller1 gingival recession were selected. 14 teeth were allocated into test group and 12 teeth in control group. following first phase of treatment, clinical parameters including the height and w...

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...

statement of the problem: melanin pigmentation of the gingiva is a crucial esthetic problem. a variety of methods have been used for gingival depigmentation. purpose: the purpose of this study was to compare the results of two treatment modalities: scalpel technique and cryotherapy with liquid nitrogen in treatment of gingival pigmentation. materials and method: twenty patients with chief compl...

Little is known about how the overall employment conditions in a country impact the likelihood of employment of newly arrived refugees. In the current study, we compare employment and determinant of employment of highly educated Middle Eastern refugees to Michigan that arrived before and after the 2007 recession. We also look at self-reported barriers to employment. Results show that the genera...

purpose: to compare bilateral medial rectus advancement (bmra) and bilateral lateral rectus recession (blrr) for treatment of consecutive exotropia in terms of final alignment. method: this randomized clinical trial was performed on 14 patients with consecutive exotropia. inclusion criteria included history of bilateral medial rectus recession, exotropia ³20 pd and far-near difference <10 pd. e...

hydrograph analysis is a complex problem in a variety of water resources investigations and its estimate is critical in the assessment of low flow characteristics of river for use in water supply, water management and pollution assessment. the paper describes different methods of base flow separation based recession analysis from daily river flow records and distinguishes the most suitable meth...

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...
