Talon cusp associated with other dental anomalies--a case report.

Talon cusp is an anomalous structure resembling an eagles talon which projects lingually from the cingulum area of an incisor. It is a rare anomaly which is commonly seen in maxillary incisors. This paper is a report of a case of Talon cusp associated with cross-bite and partial anodontia.

"Talon cusp-heredity origin"--a case report.

Talon cusp is a very unusual anomalous structure of tooth. The etiology is still unknown. It may be due to mal-interaction between ecto and mesoderm of epithelial bulgings present on premaxillary region at the time of complex odontogenesis. Genetics may have some role in the formation of Talon cusp. Talon cusp may cause clinical complications.

Treatment of the peg lateral incisor: a case study.

If guidelines are properly followed, porcelain laminate veneers can offer enviable and predictable results. Advantages of veneers include a highly esthetic outcome, durability and stability, all accomplished with a reasonably conservative approach. This case study illustrates the use of veneers to restore a peg lateral incisor of a young patient.

Dental anomaly: dens evaginatus (talon cusp).

Dens evaginatus is a developmental anomaly characterized by the occurrence of an extra cusp shaped as a tubercle projecting from the palatal or buccal surfaces (talon cusp). In the anterior dentition, dens evaginatus is more commonly found in the maxilla and on the palatal surface of the tooth. The authors present a case of dens evaginatus in a maxillary central incisor, in which the evagination was removed and routine endodontic treatment was performed.

Retrospective survey of dental anomalies and pathology detected on maxillary occlusal radiographs in children between 3 and 5 years of age.

PURPOSE: Radiographs play an important role in the diagnosis of anomalies and pathology of the oral structures of young children as well as in the interception and management of developmental problems in the dentition. The occlusal film, commonly indicated in the young child, is a helpful tool in establishing a baseline and in revealing certain region-specific dental concerns in a timely fashion. The purpose of this retrospective study was to perform a comprehensive examination of maxillary occlusal radiographs in a clinical pediatric population and to determine the prevalence of dental anomalies and pathology in the premaxilla in children between 3 and 5 years of age. METHODS: Radiographs of healthy preschool children (236 males and 264 females), who received their initial examination at the University of Texas-Houston Pediatric Dentistry Graduate Clinic during 1997 and 1998, were reviewed independently by two pediatric dentists, using a 2X magnifying lens and a standard dental light box. Interexaminer discrepancies were resolved by consultation and mutual agreement. RESULTS: Ninety-two (18%) showed no evidence of dental caries, restorations, current pathological conditions, or other anomalies. Frequencies of anomalies such as congenitally missing and supernumerary teeth were consistent with other reports. CONCLUSIONS: These observations emphasize the importance of obtaining intraoral radiographs on preschool children who are in apparent good dental health.

Preformed posterior stainless steel crowns: an update.

For almost 50 years, dentists have used stainless steel crowns for primary and permanent posterior teeth. No other type of restoration offers the convenience, low cost, durability, and reliability of such crowns when interim full-coronal coverage is required. Preformed stainless steel crowns have improved over the years. Better luting cements have been developed and different methods of crown manipulation have evolved. This article reviews stainless steel crown procedures for primary and permanent posterior teeth. Step-by-step placement of a primary molar stainless steel crown is documented and permanent molar stainless steel crown restoration is described. A method for repairing a worn-through crown also is reviewed.

Management of ectodermal dysplasia in children--an overview.

Oral rehabilitation is often difficult for the young child with ectodermal dysplasia. Most affected children require extensive dental treatment in order to restore their appearance and function. Early intervention also helps children develop a positive self-image. This paper will review the dental management and timing of different treatment modalities for children with ectodermal dysplasia.

True oligodontia with microdontia in monozygous twins: implications for reappraisal of Butler's Field Theory.

Oligodontia, which may be defined as the congenital absence of six or more teeth apart from third molars, affects less than 0.5% of the population and may occur in isolation or as part of a syndrome. This paper aims to clarify the role of genetic factors in this condition by reporting a case of a pair of identical twins and their mother who display similar patterns of oligodontia without medical problems. Each twin has 13 missing permanent teeth and their mother 16 missing teeth, but the patterns of agenesis do not conform with Butler's Field Theory according to which the distal teeth in each class are most likely to be absent. Unerupted third molars are present in both twins and all three family members display maxillary lateral incisors. Dental crown size profile patterns were computed for all three individuals and highlight a marked reduction in mesiodistal and buccolingual dimensions of the remaining teeth in each. In addition, erupted teeth showed simplified crown morphology. Oligodontia should not be viewed in isolation, but rather considered as one manifestation of a variety of dental changes in genetically susceptible individuals.

[Ectodermal dysplasia: a heterogenic deviation].

The 'problem' of ectodermal dysplasia is discussed in conjunction with a case report and a review of the literature. In a range of hereditary disorders all ectodermal structures can be effected in a variable way: reduction of the amount of hair, sweat glands and sebaceous glands, and a complete or partial anodontia of the deciduous and permanent dentition with malformation of the erupted teeth.
