@Jason Wu: That’s a very good question. I don’t think there are any studies directly comparing Ca(OH)2 with TCA for resorptive defect repairs. I think TCA is much more aggressive than Ca(OH)2 in causing necrosis for the resorptive cells. Ca(OH)2 causes a think layer of tissue necrosis. So, I would use Ca(OH)2 for internal resorption that has perforated (direct contact necrosis only) but would use TCA for External resorption that has spread inside the tooth (requiring deeper reach). Cheers! 🙂
