OBJECTIVE: To determine the incidence of @entity4500 in @entity1 with @entity14783 ( @entity14783 ) syndrome. STUDY DESIGN: This study evaluated 34 individuals with @entity14783 (age range, 2-40 years). A comprehensive dental history and a head and neck evaluation were performed on all @entity1 . Dental age was assessed in @entity1 younger than 17 years by 2 methods: (1) clinical assessment of @entity203 and (2) a radiographic method. Relationships between the chronologic age, dental developmental age, and age at @entity203 were determined. Other @entity4500 were recorded. RESULTS: Of @entity1 older than 7 years, 75% reported problems with permanent @entity203 , as evidenced by retained primary teeth or the need for elective extractions of primary teeth to allow @entity203 . None of the @entity1 experienced problems with eruption of primary teeth. Eruption of the first and second permanent molars also occurred on time. Dental @entity2175 scores were established for 14 @entity1 17 years of age or younger. In each case, the difference between chronologic age and the estimated dental developmental age was less than 12 months; however, we found a significant discrepancy between the chronologic age and the mean age of @entity203 in 80% of these @entity1 when using a particular set of standardized values. Persistence of Hertwig's epithelial root sheath was observed on histologic examination. Chronic multifocal @entity5253 was a consistent feature in @entity1 with @entity14783 recurrent @entity281 . Other @entity154 were also noted. CONCLUSION: We confirmed that a disorder of @entity203 is part of the @entity14783 . This problem occurs because of delayed primary tooth exfoliation rather than a developmental delay in the formation of the permanent dentition. The persistence of Hertwig's epithelial root sheath is unusual and may be associated with the lack of resorption of the primary teeth. Dentists should be aware of this feature of @entity14783 because timely intervention will allow normal eruption to occur.
