“…Design Methods were tested on a target sample of 300 dental panoramic radiographs (age [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Diagnostic accuracy was assessed on separate reference data (n = 1,663, age [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Root stage was the diagnostic test predicting 18 years of age.…”

by accuracy? Do population differences in dental maturity infl uence accuracy? There is an urgent need for an evidencebased reference to address some of these questions. The fi rst aim of this study was to calculate the bias (difference between dental and real age) of age-estimating methods that use mandibular third molar (M3) root formation. The probability of being at least 18 given M3 root stage is also of interest. The second aim was to apply diagnostic tests of accuracy showing how root stage discriminates between individuals at least 18 years of age and those younger and to apply this knowledge to predict the likelihood of age 18 for a single individual. For this part of this study we used a separate reference sample of 1,663 radiographs. We propose an age interval for M3 root stages to aid interpretation of the term 'on the balance of probabilities' . We highlight the similarity in M3 apex maturity between world groups from published data and illustrate how a small group difference in average age has little impact on the confi dence interval of estimated age for an individual.

Por tal motivo, alguns estudos têm voltado sua atenção para a análise do estágio de desenvolvimento dos terceiros molares e sua relação com a idade cronológica de crianças, adolescentes e adultos jovens [4][5][6][7][8][9][10][11] .…”

ResumoIntrodução: Nos últimos anos, alguns estudos foram conduzidos com o objetivo de avaliar a aplicabilidade da análise de desenvolvimento dos terceiros molares na estimativa da idade humana. No entanto, há escassez de trabalhos em amostras populacionais da região Centro-Oeste do Brasil. Objetivo: Avaliar a relação entre estágio de desenvolvimento dos terceiros molares inferiores e a idade cronológica de indivíduos da região Centro-Oeste do Brasil. Material e método: Trata-se de um estudo observacional transversal, com uma amostra constituída por 120 prontuários de pacientes entre 5 e 22 anos de idade, dos gêneros masculino e feminino, atendidos entre os anos de 2007 e 2012 na nossa instituição. O estágio de desenvolvimento dos terceiros molares inferiores foi avaliado pelo método descrito por Nolla e relacionado à idade cronológica do indivíduo por meio de regressão linear, sendo considerados significantes valores de tendência linear entre 0 e 1. Resultado: Pode-se observar que tanto a amostra composta por pacientes do gênero masculino (R 2 = 0,7495) quanto do feminino (R 2 = 0,8507) apresentaram correlação linear entre o estágio de desenvolvimento dos terceiros molares inferiores e a idade cronológica. Notou-se, ainda, que os estágios de desenvolvimento coincidiram com idades semelhantes em ambos os gêneros. Conclusão: Há relação entre a idade cronológica e o estágio de desenvolvimento dos terceiros molares inferiores na amostra estudada. Estes dados sugerem que este tipo de análise deve ser individualizada, de acordo com as características populacionais da região.Descritores: Radiografia panorâmica; terceiro molar; determinação da idade pelos dentes. AbstractIntroduction: In recent years some studies have been taken to evaluate the applicability of the third molar development analysis in the estimation of human age. However, just a few studies with the population from Midwest Brazil were performed. Objective: The present study aim to analyze the relationship between the lower third molars development stage and the chronological age of individuals in Midwest Brazil region. Material and method: This cross-sectional observational study comprised a total of 120 panoramic radiographies of patients aged 5-22 yearold, males and females, attended between 2007 and 2012 at our Institution. The third molars development stage was analyzed based on the method described by Nolla and related with the chronological age of the individual by linear regression. It was considered significant values for linear tendency between 0-1. Result: It was observed that both, male patients (R 2 = 0.7495) and females (R 2 = 0.8507), showed a linear correlation between the third molars development stage and chronological age. It was also noted that the development stages coincided with similar ages in both genders. Conclusion: There is a relationship between chronological age and developmental stage of the third molars in the sample studied. These data suggest that this type of analysis should be individualized according to the population ...

Pôle Tête, Cou, chirurgie plastique, chirurgie des brûlés, service d'odontologie, CHR Metz-Thionville, hôpital Bel-Air, Thionville, France (Reçu le 5 juin 2014, accepté le 28 septembre 2014) Résumé -Introduction : Les tétracyclines sont des antibiotiques à large spectre, connues depuis les années 1960 pour provoquer des colorations dentaires lors de l'odontogenèse. Leur prescription est contre-indiquée chez les enfants de moins de 8 ans et les femmes enceintes. Depuis les années 1990, les traitements contre l'acné inflammatoire modérée à sévère chez l'adolescent et le jeune adulte font systématiquement appel aux tétracyclines et ses dérivés semi-synthétiques. Un cas de colorations radiculaire et coronaire de troisièmes molaires visualisées après avulsion est rapporté dans cet article. Observation : Nous rapportons ici le cas d'une patiente âgée de 17 ans présentant des colorations jaune d'or en bandes au niveau coronaire et radiculaire de ses troisièmes molaires découvertes après leur avulsion, non présentes chez sa soeur jumelle. Ces dyschromies ont fait évoquer la prise d'un traitement à base de tétracycline. L'interrogatoire médical a confirmé la prise d'un traitement contre l'acné à base de lymécycline, dérivé semi-synthétique des tétracyclines, non pris par sa soeur. Discussion : La localisation et la teinte de la dyschromie concordaient avec la prise du traitement ; tout ceci était étayé par l'absence de coloration chez la soeur jumelle. Même si les colorations dentaires dues aux tétracyclines sont connues depuis longtemps, aucun article dans la littérature ne fait référence à des colorations qui seraient dues à la lymécycline.Abstract -Root and coronary stainings of the third molars caused by tetracyclines: case report and literature review. Introduction: Tetracyclines are broad-spectrum antibiotics, known since the 60s to cause tooth staining during odontogenesis. Their prescription is forbidden in children until 8 years of age and pregnant women. Since the 90s, treatments for moderate to severe inflammatory acne in teenagers and young adults always involve tetracyclines and their semi-synthetic derivates. This article relates a root and coronary staining case involving third molars discernible after being removed. Case report: This case report concerned a 17-year-old female patient with golden yellow strips which stained the third molars' roots and the crown. The staining was discovered after their extraction and was not present on the wisdom teeth of her twin sister. These dyschromias called to mind the absorption of a tetracycline-based treatment. Medical interrogation confirmed the intake of lymecycline (a semisynthetic tetracycline)-based treatment for acne which her twin sister was not treated with. Discussion: The dyschromia's localisation and shade agree with the taking of the treatment. Moreover, the lack of staining on the sister's tooth backs this assertion up. Although dental staining caused by tetracyclines has been known about for some time, there are no articles in the literature which ref...
