1/81. Management of gingival overgrowth associated with generalized enamel defects in a child. gingival overgrowth is usually associated with systemic conditions or treatment (e.g. blood dyscrasias, anti-epileptic or immunosuppressive agents). A child is presented, who had enlarged gingiva associated with a generalized enamel defect (amelogenesis imperfecta (AI), hypoplastic type) and document the periodontal and restorative management of this case.

3/81. Supraoccluding cobalt-chrome onlays in the management of amelogenesis imperfecta in children: a 2-year case report. Children suffering from the inherited dental anomaly amelogenesis imperfecta frequently present with sensitive, discolored teeth and decreased lower facial height. The aim of treatment is to reduce sensitivity while maintaining the maximum amount of hard tissue possible until the patient reaches an age at which advanced restorative techniques can be used to rehabilitate the dentition. A case is presented in which amelogenesis imperfecta in the mixed dentition was managed by the placement of adhesive cast restorations. These restorations have been in place for 2 years. ( info) |
4/81. Hypomaturation amelogenesis imperfecta: account of a family with an X-linked inheritance pattern. amelogenesis imperfecta (AI) is a heterogeneous genetic disorder which affects the dental enamel. It can have an autosomal dominant, autosomal recessive or X-linked pattern. The authors describe a case of a family with hypomaturation X-linked AI and discuss the clinical and histopathological aspects of this disorder. ( info) |
5/81. Unusual indelible enamel staining following fixed appliance treatment. Two cases are described of indelible enamel staining following fixed appliance therapy. The acquired pigmentation occurred in patients with an identifiable enamel defect prior to treatment. The interaction of factors to cause the staining is discussed and it's prevention in future cases highlighted. Subsequent restoration of the affected teeth is shown. ( info) |
6/81. amelogenesis imperfecta: functional and esthetic restoration of a severely compromised dentition. The treatment of patients with severe forms of amelogenesis imperfecta presents an interesting challenge to the dental team. A 16-year-old girl presented with a severely compromised occlusion and poor esthetics that had lowered her self-esteem. Preoperative investigations included the determination of completion of growth, an accurate diagnostic waxup, and an evaluation of clinical crown lengths. Periodontal full-flap surgery was planned to lengthen clinical crowns and create gingival harmony. This was to be followed by placement of 28 complete crowns to restore occlusal function and gain a pleasing esthetic result. All-porcelain crowns were placed from premolar to premolar in each arch (20 crowns), and porcelain-fused-to-metal crowns were placed on each molar tooth in each arch (8 crowns). The final treatment result provided this patient with a mutually protective occlusion and with esthetics that greatly enhanced her self-image. ( info) |
| Morquio syndrome is a disorder of mucopolysaccharide metabolism with specific skeletal features. The clinical and radiographic appearance of the teeth resembles hypoplastic amelogenesis imperfecta with thin enamel of normal radiodensity. The dental practitioner has a part to play in collaboration with medical colleagues in the recognition and diagnosis of this condition. ( info) |
8/81. Microabrasion of teeth with discoloration resembling hypomaturation enamel defects: four-year follow up. Microabrasion with 18% HCl and pumice to remove enamel dysmineralization and improve esthetics is an accepted and effective treatment. This technique can probably be extended even to generalized defects resembling hypomaturation amelogenesis imperfecta that appear on all erupted teeth. Five children aged 9 to 11 with two types of enamel-hypomaturation probably due to developmental defects were treated successfully by microabrasion, with marked improvement of the discoloration. The patients were followed for up to four years. During this period, no tooth-sensitivity or staining was noted. The teeth looked healthier and shinier. ( info) |
9/81. A case of amelogenesis imperfecta of deciduous and all permanent teeth. We experienced a case with severe enamel defects of both the deciduous teeth and all the permanent teeth. In order to clarify the etiology of enamel defects in this patient, we performed a dna analysis in addition to conventional examinations. Although we suspected a variety of systemic factors causing enamel defects, there was no evidence suggesting disturbances of amelogenesis. In the present case, we suspected a mutation in the amelogenin gene and performed nucleotide sequencing of the exons of the amelogenin gene, but we could not find any evidence of mutation. We suggest that a mutation of some other gene related to enamel formation or the adventitious factors contributed to the amelogenesis imperfecta in this case. ( info) |
| A case of amelogenesis imperfecta in a Nigerian is presented. Although the patient had almost full complement of teeth, their structure was physically weak and many of them were discoloured. Many of the teeth had lost their enamel and worn down rapidly causing great sensitivity, pain and aesthetic problems for the patient. The clinical features and management of this case are discussed.
