1/2. Ultrastructural study of tooth enamel with amelogenesis imperfecta in AI-nephrocalcinosis syndrome.

    This paper describes the ultrastructure of the affected enamel and the clinical features in two siblings with the syndrome of nephrocalcinosis and amelogenesis imperfecta. nephrocalcinosis was diagnosed by intravenous pyelography, and confirmed by ultrasonography and CT scan. amelogenesis imperfecta AI was diagnosed clinically and histologically. light microscopy showed that the affected enamel surfaces were rough and the enamel was hypoplastic and mainly positively birefringent. Scanning electron microscopy revealed a rough and extensively cracked enamel surface covered with oval shaped blister-like protrusions. TEM showed porous enamel consisting of loosely packed and randomly oriented thin ribbon-like crystals with little or no prismatic structure. Observations showed that hypoplasia together with hypocalcification and/or hypomaturation defects were present in the same tooth, indicating the possibility of an abnormality in interstitial matrix, leading to dystrophic calcification in the kidney and abnormal tooth enamel formation, or alternatively an involvement of two separate but closely linked genes.

2/2. An alternative restorative method for regional odontodysplasia: case report.

    A 5-year-old Caucasian male presented with early loss of multiple deciduous teeth. All the characteristics were consistent with the diagnosis of regional odontodysplasia (ROD). Significant initial findings included premature loss of multiple primary mandibular teeth and some malformed permanent teeth. The affected teeth showed hypoplastic enamel and dentin, short roots, and wide pulp chambers, and were localized in the mandibular dentition. Treatment objectives for this patient were to provide improved esthetics, restored chewing function, and space maintenance by the construction of a temporary prosthetic restoration. However, with limited tooth support and an unusual occlusal pattern, it is difficult to obtain satisfactory retention and esthetics with traditional prosthetic techniques. In this article we introduce an alternative method for fabricating a custom removable denture and discuss the prognosis of the malformed permanent dentition and further treatment plan.
