CALB2 and ameloblastoma: Alaeddini et al. [4] also found that calretinin immunoreactivity was positive only for ameloblastoma when compared to calcifying epithelial odontogenic tumour, adenomatoid odontogenic tumour, ameloblastic fibroma, and odontogenic myxoma, stating that this protein may have a role in the transition of the dental lamina remnants to ameloblastoma.
