Histological Evaluation and Management of Rare Case of Supernumerary "Ghost" Teeth.

Supernumerary teeth are teeth that exceed the normal dental formula. Their prevalence in the permanent dentition is 1-14% and they occur more frequently in maxilla with a sex ratio of 2 : 1 in favor of males. They are often associated with syndromes but there are examples of nonsyndromic multiple supernumerary teeth reported in the literature.

Possible causal relationships between competitive swimming in growing age and three-dimensional dentoalveolar development.

Background: The aim of this study was to investigate possible links between competitive swimming during the growth phase and the development of the dentoalveolar arches.

Methods: The study sample included 100 swimmers and a control group of 100 age-matched non-swimmers who had never practised swimming or related sports. Subjects who had had previous orthodontic treatment were excluded.

Age estimation in children by measurement of open apices in tooth roots: Study of a Mexican sample.

The aim of this cross-sectional study was to test the accuracy of Cameriere's European formula for age assessment in a large sample of Mexican children. The accuracy of dental age estimation was defined as how closely real age, measured as the difference between chronological age (CA) and dental age (DA), could be predicted. Digitalized orthopantomographs of 502 Mexican children (254 girls and 248 boys), aged between 5 and 15 years, were analyzed.

Adapting Häävikko's dental age for the assessment of Italian children: use of LMS and other models based on smoothing splines.

The expression 'dental age' (DA) denotes the mean age at which a given stage of dental development is achieved in a population chosen as calibrator. The rhythm at which the maturation occurs is a characteristic of a given population in a given period. When DA is determined on subjects of a population different from the calibrator, the shape of the relationship of DA to chronological age (CA) must be empirically determined to trace reference charts for DA that properly apply to this population.

Traditional plaster casts and dental digital models: intra-examiner reliability of measurements.

Unlabelled: The aim of this study was to compare the intra-examiner reliability of measurements made on plaster cast and dental digital models.

Material And Methods: Five young patients with different occlusal patterns were selected and their dental casts and corresponding digital models were obtained. Twenty expert orthodontists were asked to measure two times both the traditional and digital models.

Häävikko's method to assess dental age in Italian children.

The aim of this study was to determine if Häävikko's maturation standards are applicable to Italian children. The sample included 500 healthy Caucasian children 3.9-15.
