The effect of surface roughness on the Weibull distribution of porcelain strength
Weibull modulus Surface roughness Flexural strength
2010/11/26
The purpose of the present study was to test the hypothesis that glazing will affect the Weibull modulus or the mean flexural strength of dental porcelain. Four groups (n = 30) of specimens were prepa...
Assessment in vitro of brushing on dental surface roughness alteration by laser interferometry
Tooth abrasion Dentifrices Toothbrushing
2009/10/16
Noncarious cervical lesions (NCCLs) are considered to be of multifactorial origin, normally associated with inadequate brushing. This study assessed the influence in vitro of simulated brushing on NCC...
