The Effect of Occlusal Discrepancies on Gingival Width

Journal of Periodontology, 2004
Background: A relationship between occlusal forces and gingival recession has been postulated in the past. However, minimal data are available to demonstrate a causal relationship between occlusal forces and recession.Methods: The records from a private practice limited to periodontics were reviewed to find patients who had complete periodontal ...

Correction of finite slit width effects on Raman line widths

Spectrochimica Acta Part A: Molecular Spectroscopy, 1980
Abstract An equation is derived for the correction of the finite slit width effect on line widths of Lorentzian Raman lines. It holds for up to S/δa = 0.7, more applicable than those proposed previously. A method is also proposed for obtaining the true isotropic line width from observed parallel and perpendicular polarized spectra.
