Apart from natural photosensitizers, TB (coronal 8.51±0.74 MPa, middle 6.95±0.91MPa, apical 5.18±0.74MPa) an artificial photosensitizer displayed bond values comparable to CP and P. A logical explanation for this outcome is TB at this concentration (100mg/l) when activated at 638nm wavelength, might have boosted cross-linking of collagen fibrils in the dentin to resin providing a better outcome.17,18 Moreover, diffusion capacity of TB, hydrophobic nature and light energy fluency of TB may have resulted in favorable EBS. The gene discussed is CP; the disease is tuberculosis.
