The Herbst appliance –first presented to the dental community in 1909is a traditional fixed bite-jumping device aiming at skeletal and/or dentoalveolar correction of class II malocclusions. It is especially indicated in the permanent dentition at or just after the pubertal peak of growth (Pancherz, 1997). An upper age limit for successful treatment with the Herbst device is difficult to define ...

The $L$-fuzzy approximation operator associated with an $L$-fuzzy approximation space $(X,R)$ turns out to be a saturated $L$-fuzzy closure (interior) operator on a set $X$ precisely when the relation $R$ is reflexive and transitive. We investigate the relations between $L$-fuzzy approximation spaces and $L$-(fuzzy) topological spaces.

If orthodontists and restorative dentists establish the interdisciplinary approach to esthetic dentistry, the esthetic and functional outcome of their combined efforts will be greatly enhanced. This article describes satisfying esthetic results obtained by the distribution of space for restoration by orthodontic treatment and porcelain laminate veneers in uneven space between maxillary anterior...

Specimens of human immature permanent teeth after regenerative endodontic treatment (RET) are sparse. This case report describes the histologic and immunohistochemical findings of tissue formed in the canal space of a human immature permanent tooth with apical periodontitis after RET. A patient presenting with immature human permanent tooth #29 with apical periodontitis underwent RET. At the 10...

Under the axiom of choice, every first countable space is a FréchetUrysohn space. Although, in its absence even R may fail to be a sequential space. Our goal in this paper is to discuss under which set-theoretic conditions some topological classes, such as the first countable spaces, the metric spaces or the subspaces of R, are classes of Fréchet-Urysohn or sequential spaces. In this context, i...

The combined treatment of severe dentofacial deformities normally consists of at least three steps: The preand post-operative orthodontic treatment and the treatment between surgical correction. The accuracy of the surgical planning and especially the surgery itself are crucial for the duration of the postoperative orthodontic treatment. Main reason for the segmentation of the jaws is the accel...

Aim: Orthodontic treatment is routinely carried out in patients with the purpose of correcting various forms of dental malocclusions. Retraction of the canines can be achieved either individually or along with incisor. Pentraxin-3 (PTX-3) is regarded as the true independent indicator of disease activity. Hence, we undertook the present study to assess and compare the level of PTX-3 in patients ...
