The teeth are formed during intrauterine life (i.e., gestation) during the odontogenesis stage. During this period, the teeth move until they enter the oral cavity. This course covers various stages of dental development, namely, initiation, proliferation, histodifferentiation, morphodifferentiation, and apposition. The talon cusp is an anomaly that occurs during morphodifferentiation, and this...

Introduction: Since crown lengthening surgery could be accompanied by stress, pain and discomfort, knowledge about its predisposing factors could reduce the demands for such surgery.The aim of this study was to identify the most important indications of crown lengthening surgery in order to present new ideas to clinicians on how to reduce the need for this surgery. Methods: This cross-sectio...

For an arbitrary even genus n we show that the subspace of Siegel cusp forms of weight k + n/2 generated by Ikeda lifts of elliptic cusp forms of weight 2k can be characterized by certain linear relations among Fourier coefficients. This generatizes the work of Kohnen and Kojima. We investigate the analogous subspaces of hermitian and quaternionic cusp forms. Introduction Ikeda [7] constructed ...

In this paper, we prove the boundedness of foliated surfaces $$(X,{{\mathscr {F}}})$$ which are minimal partial du Val resolutions canonical models $$(X_c,{{\mathscr {F}}}_c)$$ general type. For applications, show non-cusp singularities on type and effective generation complement cusp singularities.

An integrated experimental and theoretical approach is proposed for the evaluation of stress within a natural tooth during bruxing. A physical model was developed that used strain gauges bonded to the buccal and lingual heights of contour of extracted, intact maxillary premolar teeth for the validation of a two-dimensional finite element model of a natural, intact maxillary premolar tooth. Resu...

A 34 year old man presented with an inferior non-Q-wave myocardial infarction. Echocardiography showed a bicuspid aortic valve with aortic outflow obstruction. Left coronary cusp morphology was normal but the right coronary cusp was grossly distorted and replaced by a mobile echodense mass encroaching upon the aortic valve orifice. The aortic valve was replaced and pathological analysis of the ...

The aim of this study was to analyze the stresses that develop by oblique and vertical forces in endodontically treated maxillary second premolars that were restored with resin composite. Additionally, in our study the effects of the different restorative approaches and use of different base materials on stress formation were analyzed using three-dimensional finite element stress analysis. For ...
