ABSTRACT Objective The purpose of the study was to verify the relationship between mandibular canine calcification and skeletal maturity, and mandibular canine calcification could be used as a first-level diagnostic tool to estimate the timing of the pubertal growth spurt. Materials and methods Data were obtained from hand—wrist radiographs and intraoral periapical radiographs of left mandibular canine. Totally, 221 boys and 191 girls, the age ranging from 7 to 15 years, were selected to depict varying stages of growth. Kappa and t test statistics were applied. Skeletal age was determined as described by Greulich and Pyle, and the maturational patterns of the indicators were evaluated using the 11-grade system of Fishman. The stages from E to H as described by Demirjian's stages of dental calcification were taken in this study instead of A to H. Results The epiphyseal widening for boys at 8.1 years and girls at 7.7 years, the ossification of the adductor sesamoid for boys at 12.2 years and for girls at 11.6 years, capping of epiphysis for boys at 11 years and for girls at 10 years, fusion of epiphysis in distal and middle phalanx in the third finger for boys at 13.8 years and for girls at 12.7 years, and fusion of epiphysis in the radius for boys at 14.4 years and for girls at 13 years were seen. The relationship between the various stages of calcification of mandibular canine with skeletal age are as follows: Boys: Stage E at 6.4, stage F at 8.9 years, stage G at 10.9, and stage H at 14 years Girls: Stage E at 6.1, stage F at 8.2 years, stage G at 10.46, and stage H at 12.94 years. The results showed stages E and F were coincident with the epiphyseal widening in the third finger proximal and middle phalanx and middle phalanx of the fifth finger. Stage G was coincident with the ossification of adductor sesamoid, capping of third finger middle phalanx, distal phalanx, and fifth finger middle phalanx, indicating its association with the accelerative phase of growth. Stage H was coincident with a fusion of proximal, middle, distal phalanx of the third finger, and fusion of radius, indicating its association with the decelerative phase of growth. Stage G was an ideal time for any orthodontic treatment, particularly functional appliances. Conclusion Based on the findings of this study, a close association existed between mandibular canine calcification stages and skeletal maturity indicators.

ABSTRACT Aims The purpose of this study was to assess the reliability of permanent mandibular canine tooth calcification as an indicator of skeletal maturity in Karnataka population by comparing it with the ossification stages of the middle phalanx of the left third finger and also to compare the sexual dimorphism in the timing of these events. Methods This study was performed on 100 subjects (50 boys and 50 girls) of South Indian origin aged 10 to 14 years. Radiovisiographs of the middle phalanx of the left third finger and Orthopantomographs were obtained and assessed for the stages of calcification using the methods described by Hagg and Taranger and by Demirjian et al respectively. The correlation between various stages of lower canine calcification and stages of MP3 ossification was assessed for both the sexes using Chi-square test and percentage distributions. Results The associations were statistically significant only between MP3-F and canine F stages in both sexes (88% for boys, 59% for girls) and MP3-H and canine H stages in boys (100%). Also girls showed an advanced trend in dental maturation. Conclusion The mandibular canine calcification stages alone are not as reliable an indicator as MP3 stages for assessing the skeletal maturity in Karnataka population.

Maturity Assessment

Assessment of skeletal maturity is an integral part of interceptive diagnosis and treatment planning. The present day methods of skeletal maturity assessment like the hand-wrist radiographs or cervical vertebrae radiographs are expensive, require elaborate equipment and accounts for high radiation exposure, especially for growing children. The present study was thus undertaken to provide a simple and practical method of skeletal maturity assessment using the developmental stages of the middle phalanx of the third finger (MP3) as seen on an IOPA film taken using a standard dental x-ray machine. The results of the study showed that this simple method was highly reliable and could be used as an alternative method to assess the skeletal maturity of growing children.

The aim of the study is a comparative analysis of the linear parameters of the length and width of the diaphysis of the middle phalanges in children and adolescents of Tajikistan and Western India, and also the possibility of using these linear parameters to establish the age of children of the compared ethnic groups. On 325 radiographs of the right hand in male children and adolescents of the Kanibadam region of the Republic of Tajikistan and the city of Mumbai (Western India) at the age of 6-17 years, the length of the middle phalanges and the width of their diaphysis were determined. To determine the relationship between the age of children of the compared ethnic groups and the linear parameters of the length and width of the shaft of the phalanges, Spearman's nonparametric correlation coefficient was used. Comparative assessment of the values ​​of indicators by age was carried out by the method of parametric and non-parametric analysis. In boys of Tajikistan, the closest correlation was established between the age of children and the length of the middle phalanx of the third finger, while in their Indian peers this ratio was determined evenly for the II-IV fingers of the hand. The width of the diaphysis of the phalanges of the fourth finger increased most significantly with age in boys of Tajikistan, and in the Indians, the width of the third finger, the smallest increase in the width of the diaphysis in the compared groups was determined for the phalanges of the second finger. The linear parameters of the middle phalanges of the hand can be used to identify the age of children and adolescents in Tajikistan and Western India at the age of 6-17 years. For Tajik children, the best predictor of age is the linear parameter of the length of the middle phalanx of the index, and for their Indian peers, the length of the middle phalanx of the II-IV fingers is equally.

Abstract: The assessment of skeletal age is of utmost importance not only in the field of anthropology, forensic medicine, pediatrics, endocrinology but also in orthodontics and jaw orthopedics. Bone age refers to the individual’s biological development which can differ within a relatively wide range for the same chronological age. Therefore, accurate assessment of skeletal maturity and pubertal growth plays an important role in establishing a diagnosis for certain diseases. In addition, it is essential for proper timing and success of treatments in many cases. Currently, there are many methods available to determine skeletal age and pubertal growth spurt. During growth, bones undergo significant changes, the sequence of which is strongly determined. These changes can be measured by various methods including radiological examinations. More specifically, these classical methods are often based on the radiological evaluation of morphological changes in the hand bones and cervical vertebrae. Methods based on dental development also exist to assess the biologic maturity of an individual. However, thanks to three-dimensional imaging techniques and molecular diagnostic methods, even more accurate tests can be performed to determine biological maturity. These modern methods rely on the information obtained from the cone-beam computer tomograph records and on the measurements of biomarkers present in different circulatory or other body fluids. The purpose of this summary is to provide an overview of the various classical and modern methods for the assessment of skeletal age that could aid us in many fields of science.

Der Beitrag widmet sich der Frage historischer Folgeverhältnisse in der Kunst. Gegenüber dem Gedanken, dass es ein ursprüngliches Werk in der Reihe von Werken gibt, das späteren Werken seinen Sinn gibt, schlägt der Text vor, das Verhältnis umgekehrt zu denken: Im Lichte späterer Werke wird der Sinn früherer Werke neu ausgehandelt. Dazu geht der Text in drei Schritten vor. Im ersten Teil formuliert er unter der Überschrift ›Form‹ in kritischer Abgrenzung zu Danto und Eco mit Adorno den Gedanken, dass Kunstwerke eigensinnig konstituierte Gegenstände sind. Die im Gedanken der Neuverhandlung früherer Werke im Lichte späterer Werke vorausgesetzte Unbestimmtheit des Sinns von Kunstwerken wird im zweiten Teil unter dem Schlagwort ›Zeitlichkeit‹ anhand des Paradigmas der Improvisation erörtert. Der dritte und letzte Teil wendet diese improvisatorische Logik unter dem Label ›Neuaushandlung‹ dann dezidiert auf das Verhältnis von Vorbild und Nachbild an. The article proposes a new understanding of historical succession in the realm of art. In contrast to the idea that there is an original work in the series of works that gives meaning to the works that come later, the text proposes to think it exactly the other way round: in the light of later works, the meanings of earlier works are renegotiated. The text proceeds in three steps to develop this idea. Under the heading ›Form‹ it develops in the first part a critical reading of Danto’s and Eco’s notion of the constitution of the artworks and argues with Adorno that each powerful work develops its own language. In the second part, the vagueness of the meaning of works of art presupposed in the idea of renegotiating earlier works in the light of later works is discussed under the term ›Temporality‹ in terms of the logic of improvisation. The third and final part uses this improvisational logic under the label ›Renegotiation‹ to understand the relationship between model and afterimage in the realm of art.

Running is one of the most popular activities in the world. Runners’ attitudes and behaviors vary depending on their running style. This study aims to construct different measures of running specialization based on the theory of specialization. This study also tests a runner’s stage of specialization segmentation based on recreation specialization and examines the predictive relationship between a runner’s specialization and event attachment. Three groups of sampling data assess the performance of diverse specialization measures for running in three marathon events. First, two surveys were conducted with marathon participants to assess the performance of diverse specialization measures for runners. Second, the third dataset was used to examine the relationship between a runner’s recreation specialization and event attachment.The study results showed that the 15 measures of specialization showed a good fit to the data. Our research showed how runners’ recreation specialization is connected to their event attachment. In addition, this study suggested event management for subdivisions of runners. Its practical implication is that recreation specialization for running can help us understand event attachment.
