Many of Glycobyological aspects of human development remain still unclear, mainly in oral science, and this could be observed in a lack of literature with few and old papers about this subject. During tooth histo-morphogenesis changes occur in basement membrane composition, expression of signaling molecules and in localization of cell surface components, where glyco components could be involved. In this sense, this work aimed to analyze the ConA ligands commonly founded in glycoproteins cores and UEA-I ligands since fucolization is a Key event in many physiological and pathological processes. Therefore 15 jaws of human fetuses were ethically obtained, histologicaly processed and then submitted to lectin histochemistry with appropriated controls. The... |

This study investigated the immunodetection of PTCH in epithelial components of dental follicles associated with impacted third molars without radiographic signs of pathosis. One hundred and five specimens of dental follicles associated with impacted third molars with incomplete rhizogenesis (between Nolla's stage 6 and 9) were surgically removed from 56 patients. Epithelial cell proliferation was determined by using immunohistochemical labeling. Statistical analysis was performed using Fisher exact test and a level of significance of 5%. Of the 105 dental follicles collected, 3 were PTCH-positive. The specimens with squamous metaplasia and epithelial hyperplasia had higher rates of positivity for PTCH, as well as those with active remnants of odontogenic... |
