Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The expected outcome is to obtain clinical success, achieving the reduction of microorganisms. We will collect dentin sample before and after the treatment (TFDa). Seven days after sample processing, we will done the colony forming units (CFU) count in these two moments. After applying appropriate statistical tests we will compare the frequency reduction of microorganisms related to the onset and progression of caries as microorganisms total, total Streptococcus, Streptococcus mutans and Lactobacillus. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary expected outcome is the reduction of microorganisms unrelated to the initiation and development of dental caries but in several studies are also found in carious lesions such as Candida and the Enterococcus faecalis. We also will collect dentin sample before and after the treatment (TFDa). Seven days after sample processing, we will done the colony forming units (CFU) count in these two moments. After applying appropriate statistical tests we will compare the frequency reduction of these microorganisms. | — |
