Jedná se o onemocnění systémového původu postihující jeden až čtyři první stálé moláry, které je často spojené poškozením stálých Toto nemá zcela objasněnou etiologii. literatuře jsou zmíněny vlivy vnějšího prostředí, ...

introdouction: esthetic demands of patients have led to the introduction of tooth-colored restorations wherecomposite resins are bonded to the enamel using acid etch techniques. total etch adhesion systems are still considered as the gold standard among bonding systems. however, clinicians have a tendency to use adhesive systems with simpler application procedures. the aim of the present study ...

Mouse incisors are regenerative tissues that grow continuously throughout life. The renewal of dental epithelium-producing enamel matrix and/or induction of dentin formation by mesenchymal cells is performed by stem cells that reside in cervical loop of the incisor apex. However, little is known about the mechanisms of stem cell compartment formation. Recently, a mouse incisor was used as a mod...

The development of the lower incisor in the mouse was investigated from histological sections using computer-aided 3D reconstructions. At ED 13.0, the incisor was still at the bud stage. At ED 13.5, the initial cap was delimited by a short cervical loop, the development of which proceeded on the labial side, but was largely retarded on the medial side. This difference was maintained up to ED 15...

     Osteosarcoma (OS) is a malignant tumor that induces formation of osteoid or immature bone and rarely occurs in maxilla. Maxillofacial OSs are reported to occur in the third to fifth decades that is 1-2 decades later than the mean age for OS of long bones. The present case is a 62-year-old man with facial asymmetry and pain in his left upper jaw. Intraoral examination showed a bony hard, te...

Open bite (OB) is a generalized term, which could incorporate subgroups that react differently to vertical correction. The objectives of the present study were to detect vertical treatment changes in incomplete bite (IB: inter-incisor overlap with no lower incisor contact with teeth or palate) and OB (no inter-incisor overlap) groups compared with a complete bite (CB: inter-incisor overlap with...

OBJECTIVE Evaluation of the presence of the maxillary lateral incisor in the cleft in patients with complete unilateral cleft lip and palate treated with the use of various surgical protocols. MATERIAL AND METHODS A retrospective analysis was conducted as regards diagnostic models, panoramic radiographs and tooth images of the cleft of 75 patients with complete unilateral cleft lip and palate...

in vitro maturation (ivm) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. this review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. the review is based on literature reports and the author’s experience. in ivm cycles,...

Any type of aesthetic correction in dental practice is always a challenging task, especially when it is complicated with cleft lip and alveolus. Careful examination and correct decision making at early stage of treatment and multi disciplinary approach is always necessary for long term success. This paper described a multidisciplinary approach in managing a 19-year-old female patient with unila...
