Abstract

Introduction: The low level laser (LLLT) has been used in medicine and dentistry with different clinical effects, such as increasing the rate of healing of soft and hard tissues. While it is true the effects at the cellular level are not entirely clear. Objective: To evaluate the effect of therapy with low level laser (LLLT) on human osteosarcoma cells (SAOS-2), and observe changes at the level of viability or cell proliferation after application.

Material and methods: This is a study in different cell cultures, SAOS-2, where we have a control group and three groups in which the application of low level laser is different in time of energy application as received. For data analysis we used the statistical package SPPSS 18. For the descriptive analysis of the data was calculated indices of central tendency (mean and median), the index of dispersion (standard desviation), and extreme values (minimum and maximum).

Results: The use of low level laser does not show statistically significant effects at the level of cell proliferation in osteoblasts but a tendency to increase cell proliferation in cultures.

Conclusions: The effects should be better studied before it is considered as an accelerator of orthodontic movement stimulus.
