脉冲CO2激光与氟化氨银联合处理对人牙本质超微结构的影响
脉冲CO2激光 氟化氨银 牙本质 超微结构
2012/6/25
观察脉冲CO2激光和38%氟化氨银联合处理对人牙本质超微结构的影响。方法 将人离体前磨牙预备成相同的4块牙本质标本,分为对照组（不处理）、激光照射组、氟化氨银组和联合处理组,采用扫描电镜观察牙本质的超微结构。结果 扫描电镜下可见,对照组的牙本质小管结构明显,切面不整齐呈杂乱锐利的断茬样结构;激光照射组牙本质表面熔融平坦,牙本质小管完全封闭;氟化氨银组牙本质表面有泡状结构隆起,覆盖牙本质表面,牙本质...
Chemical, Morphological and Thermal Effects of 10.6-μm CO2 Laser on the Inhibition of Enamel Demineralization
FT-Raman spectroscopy SEM Cross-sectional microhardness
2009/9/14
Studies have shown that enamel can be modified by pulsed CO2 laser to form a more acid-resistant substrate. This study evaluated the effects of a 10.6-μm CO2 laser on enamel surface morphology and che...

2009/5/15
Objective: This study compared the effect of CO2 laser + scaling and root planing (SRP) versus SRP alone in the treatment of chronic periodontitis.
Method: Fifteen healthy patients with moderate per...
Effects of CO2 Laser Irradiation on Bone Sialoprotein Transcription
bone sialoprotein osteoblasts transcriptional regulation
2009/5/6
Laser irradiation at low photon intensities has a stimulating effect on cell and tissues. Although the carbon dioxide (CO2) laser is a surgical rather than a therapeutic laser, we have attempted to us...

CO2 laser Pain Orthodontics
2008/10/29
Objective: To test the hypothesis that there is no difference in the pain associated with orthodontic force application after the application of local CO2 laser irradiation to the teeth involved.Mater...
Observations of pulpotomy in rats using in vivo Micro-CT—The changes after treatment of formocresol and calcium hydroxide pulpotomies or CO2 laser irradiation—
Calcium hydroxide CO2 laser, Formocreso Longitudinal changes Pulpotomy R_mCT®
2008/4/16
In general, pulpotomy is evaluated by pathological examination of sacrificed animals at each observing stage. Not only lots of small animals have to devote itself to experimentation, but also the resu...
