Table 1. Frequency Distribution of the Sample Number (Bone Defects) vs. Exposure to LLLT or Photodynamic Therapy Per Aspect Radiographics .

Models of Therapy	Hyperlucency	Radio-opaque	P
LLLT	5	3	0.038
PDT + LLLT	1	7

PDT, Photodynamic Therapy;LLLT, low level light therapy

Note: PDT, Photodynamic Therapy; LLLT, low level light therapy (emission of red (Arsenic and Gallium) laser, only one point (90s), pulsatile, λ = 660nm, 40mW and total dose of 2.3 J/cm2. Proximal bone defects were exposed to the laser in the postoperative period. Distal bone defects were challenged (PDT + LLLT) with methylene blue (10 μL to 0.01%), with transoperative laser exposure (PDT), and exposed to postoperative laser therapy. For statistical analysis was used Chi Square test (χ2); CI - confidence interval equal 95%; Degrees of freedom (df) = n-1.

For statistical analysis was used chi-square test.
