RESUMO
Tooth and nail syndrome, an autosomal dominant condition, is characterized by hypodontia and nail dysplasia. Mandibular incisors, second molars and maxillary canines are the most frequently missing teeth. Tooth shape may vary and conical and narrow crowns are common. Nail dysplasia affects fingernails and toenails and is often more severe in childhood. Nails may be spoon-shaped, ridged, slow growing and easily broken. The clinical and radiographic features of a father and son presenting with this rare condition are described.

Anterior palatal tooth wear is easily recognized, but its precise pathogenesis remains unknown. Treatment of this condition with cast-alloy palatal veneers used in combination with an adhesive cement is described. Forty-eight patients, aged 11 to 71, were treated with a total of 210 cast metal veneers over a period of 56 months. Twenty-three of the restorations failed, resulting in an overall success rate of 89%. All failures were confined to 13 patients. A glass polyalkenoate cement was less effective than a chemically active resin composite luting agent. Nickel-chromium veneers cemented with activated resin composite recorded a survival probability of 0.74 at 56 months. Adhesive cast-alloy veneers provided a useful method of restoring maxillary anterior teeth affected by acid erosion.

A case is reported of an unusual cause of localized nasal discharge. A 6-year-old girl presented complaining of pain and discharge from the left nostril. Clinical and radiological evaluation revealed the cause of the symptoms to be a previously asymptomatic intruded primary incisor on the floor of the nasal cavity. The tooth was removed under general anaesthesia and healing occurred without complication.

Adhesive cast restorations placed without tooth preparation were used to restore the teeth of patients affected by either amelogenesis or dentinogenesis imperfecta. Twelve patients aged between 7 and 18 years were treated and in total 64 cast restorations were placed. At the time of cementation, the vertical dimension was increased by the thickness of restorative material placed on the functioning surfaces of the restored teeth. Full occlusion was restored for all individuals, with only one casting being lost. The castings have been placed for intervals between 10 and 54 months.

Composite and porcelain veneers offer a conservative method of masking discolouration of the teeth of younger patients. Composite veneers are the less destructive of tooth tissue, but also the less durable. This two-part article reviews the use of veneers in treating the adolescent patient. Part 1 described the clinical procedure for veneering with composites. Part 2 now gives a guide to porcelain veneer technique, and then draws some overall conclusions.

Composite veneers are the less destructive of tooth tissue, but also the less durable. This two-part article reviews the use of veneers in treating the adolescent patient. Part 1 examines indications for treatment and gives a step-by-step guide to the clinical procedure for veneering with composite. Next month, Part 2 will cover porcelain veneers and draw some overall conclusions.
