Evaluation of the effect of two types of laser on the growth of streptococcus mutans.

This study was done to compare the antibacterial effect of Photodynamic therapy (PDT) on streptococcus mutans (S. mutans) using two different light sources and photosensitizers (PS). Materials and methods: Five groups were studied in this research:no light and no toluidine blue ortho (TBO) as PS for control group, irradiation only (CO2 laser or Nd:YAG laser), and irradiation with PS (CO2 laser and TBO or Nd:YAG laser and TBO). Standard suspensions of S. mutans, based on the type of group, were used in different PDTs. Bacterial suspension from each treatment was subcultured onto the surface of Mueller-Hinton agar plates, and bacterial growth was assessed. The results were analyzed by analysis of variance (ANOVA). Results: There was a statistically significant reduction in the viability of S. mutans in TBO with CO2 laser and TBO with Nd:YAG laser groups (p value

Humans have made many dietary mistakes over the years but two mistakes, in particular, stand out: close contact with animals, mostly ruminants, who conveyed their diseases to us and the adoption of the seeds of grasses as human food. These two practices not only changed the course of human history but also human disease. Over the last several centuries, Westerners have populated North America, South America, Pacific islands and other regions. Equipped with superior tools of warfare such as swords and muskets, contact with Westerners decimated indigenous people such as the millions of native Americans, Aztecs, and Amazonian...
