Abstract

A new sectional partial denture utilizing lock mechanism (lock denture) has been developed. Utilizing the lock mechanism, two parts of sectional partial denture are locked together easily and tightly. A lock denture has been constructed for an upper removable partial denture, has been worn for over three months and has clinically been proven to obtain good function and esthetics.

Maxillary ameloblastic carcinoma in a child.

We report an extremely rare occurrence of ameloblastic carcinoma located in the maxilla of a pediatric patient. Wide surgical resection was done along with adjuvant radiotherapy because of involved surgical margins. Histopathological diagnosis was established with morphological features of both ameloblastoma and carcinoma.

Claudins 1, 4, 5, 7 and occludin in ameloblastomas and developing human teeth.

BACKGROUND: To analyze the distribution pattern of claudins 1, 4, 5, 7 and occludin in benign and malignant ameloblastomas and developing human teeth. METHODS: Paraffin-embedded tissue specimens of 25 benign and four malignant ameloblastomas and two developing human teeth were examined immunohistochemically using antibodies against claudins 1, 4, 5, 7 and occludin. RESULTS: In ameloblastomas strongest expression was seen for claudins 1 and 7 while claudin 4 was expressed less frequently. Claudin 5 and occludin were seen only in a minority of cases. There were no evident differences in the expression of claudins or occludin neither between different histologic subtypes of ameloblastomas nor between benign or malignant cases. The strongest expression for claudins was present in the central stellatum reticulum-like cells surrounding the microcysts and in the areas with squamous differentiation of the ameloblastomas. In developing teeth both claudin 1 and 7 stained strongly in the enamel epithelium, ameloblasts, and enamel matrix, but staining for claudin 4 was relatively weak. Claudin 5 was preferentially expressed only in vessels, and occludin staining ranged from negative to weak in ameloblastomas and teeth germs. CONCLUSION: There were no clear differences in the expression levels between benign and malignant ameloblastic tumors. The overexpression of claudins in the areas with microcyst formation may indicate their attempt to maintain the interepithelial cohesion of the cells. The strong immunoreactivity of ameloblasts and newly synthesized enamel matrix for claudins 1 and 7 indicates that they may be involved in cell signaling influencing enamel formation.
