Studies of the chronological course of wisdom Tooth Eruption in a German population
Journal of Forensic and Legal Medicine, 2008Co-Authors: A. Olze, R. Schulz, C. Peschke, A. SchmelingAbstract:Forensic age estimation in living subjects has gained increasing significance in recent years. In dental age estimation, Tooth Eruption is a parameter of developmental morphology that can be analyzed by either clinical examination or by evaluation of dental X-rays. In the present study, we determined the stage of wisdom Tooth Eruption in 144 male and 522 female German subjects aged 12-26 years based on radiological evidence from 666 conventional orthopantomograms. The results presented here provide useful data on the age of alveolar, gingival, and complete emergence of the third molars in the occlusal plane that can be utilized for the forensic estimation of the minimum and most probable ages of individuals under investigation.

Comparative study on the effect of ethnicity on wisdom Tooth Eruption
International Journal of Legal Medicine, 2007Co-Authors: A. Olze, P. Niekerk, T. Ishikawa, B. L. Zhu, R. Schulz, H. Maeda, A. SchmelingAbstract:The current knowledge base for evaluating the influence of ethnic origin on wisdom Tooth Eruption is still inadequate. We therefore analyzed and compared the chronology of wisdom Tooth Eruption in three ethnic populations—German, Japanese, and black South African—based on evidence from 2,482 conventional orthopantomograms. The investigated German population ranked in the middle in terms of the age of wisdom Tooth Eruption. The black South African population was the fastest and the Japanese population the slowest in terms of reaching the respective Eruption stages. Population-specific reference data should be used when evaluating wisdom Tooth Eruption for the purpose of forensic age estimation.

Studies of the chronological course of wisdom Tooth Eruption in a Japanese population.
Forensic science international, 2007Co-Authors: A. Olze, T. Ishikawa, B. L. Zhu, R. Schulz, H. Maeda, A Heinecke, A. SchmelingAbstract:The importance of forensic age estimation in living subjects has grown over the last few years. In dental age estimation, Tooth Eruption is a parameter of developmental morphology that can be analyzed by either clinical examination or by evaluation of dental X-rays. In the present study, we determined the stage of wisdom Tooth Eruption in 549 male and 751 female Japanese subjects aged 14-26 years based on radiological evidence from 1300 conventional orthopantomograms. The results presented here provide useful data on the age of alveolar, gingival, and complete emergence of the third molars in the occlusal plane that can be utilized for forensic estimation of the minimum and most probable ages of investigated persons.

Nutritional status is associated with permanent Tooth Eruption chronology
Brazilian Journal of Oral Sciences, 2017Co-Authors: Juliana Arid, Mariana Cecília Vitiello, Erika Calvano Küchler, Alexandra Mussolino De Queiroz, Raquel Assed Bezerra Da Silva, Lea Assed Bezerra Da Silva, Paulo Nelson-filhoAbstract:Either obesity and underweight are public health concerns that affect the development of children. Aim: The aim of this study was to evaluate whether the nutritional status affects permanent Tooth Eruption chronology in Brazilian children. Methods: A hundred sixty children were examined by a pediatric dentistry and at the clinical examination, the number of erupted permanent teeth was evaluated. The anthropometric measurements of the children were determined, and they were divided into groups: underweight, eutrophic, overweight and obese. The association between delayed Tooth Eruption and nutritional status groups was evaluated using chi-square test. The Shapiro–Wilk test was used to verify the normality of the data. To compare the mean number of delayed teeth according to nutritional status’ groups Kruskal-Wallis test with multiple comparison by Dunn's test was performed. Results: Fifty-six children had delayed Tooth Eruption in at least one permanent teeth and delayed Tooth Eruption was more common in underweight children than in eutrophic children (p=0.0091). Conclusion: In conclusion, our study suggests that underweight Brazilian children have a higher incidence of delayed Eruption.

Tooth Eruption and cementum formation in the Runx2/Cbfa1 heterozygous mouse
Archives of Oral Biology, 2003Co-Authors: Shujuan Zou, Rena N. D'souza, T Ahlberg, Antonius L. J. J. BronckersAbstract:Abstract Cleidocranial dysplasia (CCD) is an autosomal dominant human disorder that affects development of bones and teeth. The dental disorders in CCD patients include formation of supernumerary teeth, delayed Tooth Eruption, and lack of formation of cellular cementum in permanent teeth. This disorder involves a mutation in the osteoblast-specific transcription factor Runx2/Cbfa1, leading to haploinsufficiency of the Runx2/Cbfa1 protein. Here, we examined if Runx2/Cbfa1 heterozygous mice (with one functional allele for Runx2/Cbfa1) exhibit similar changes in Tooth Eruption, and dental cementum formation as in CCD patients. Heads of Runx2/Cbfa1 heterogeneous and wildtype mice aged days 16–35 postnatally were serially sectioned and stained with hematoxylin–eosin or for tartrate resistant acid phosphatase (TRAP) to identify osteoclasts. The results showed that the Eruption pattern of the first and second molars in maxilla and mandible in Runx2/Cbfa1 +/− mice was the same as in wildtype animals. No clear difference in distribution or in the (estimated) number of osteoclasts was found. Cellular cement at the apical portions of the molar roots was present in both groups. The data suggests that in the mouse one allele for Runx2/Cbfa1 is sufficient for an undisturbed Tooth Eruption and an apparently normal formation of the periodontium.
