اثر مداخلات مختلف بر مورفولوژی دندان Bleach شده با لیزر: ارزیابی با میکروسکوپ الکترونی روبشی
Objective: The aim of this study was to evaluate and compare the effect of dental surface treatment with Er:YAG , Nd:YAG ,CO2 lasers and sodium ascorbate to recently laser bleached enamel by scanning electron microscope (SEM). Methods: 15caries-free extracted human third molars were selected for this study. The samples were bleached by Heydent JW power activated by diode laser 810 nm. After 7 d...
متن کاملUnderstanding the response of dental enamel to mid-infrared radiation
Human dental enamel has a porous mesostructure at the nanometre to micrometer scales that affects its thermal and mechanical properties relevant to laser treatment. We exploit finite element models to investigate the response of this mesostructured enamel to mid infrared lasers (CO2 at 10.6 μm and Er:YAG at 2.94 μm). Our models might easily be adapted to investigate ablation of other brittle co...
متن کاملFT-Raman spectroscopic characterization of enamel surfaces irradiated with Nd:YAG and Er:YAG lasers
Background. Despite recent advances in dental caries prevention, caries is common and remains a serious health problem. Laser irradiation is one of the most common methods in preventive measures in recent years. Raman spectroscopy technique is utilized to study the microcrystalline structure of dental enamel. In this study, FT-Raman spectroscopy was used to evaluate chemical changes in enamel s...
