Accurate root canal length determination is a crucial factor for successful root canal treatment. The study provides insight into the principles of operation of electronic apex locators. It showed that the accuracy of the ratio method varied depending on the set of frequencies used for evaluation as well as on the selected impedance ratio. With the obtained optimal measuring parameters, the impedance ratio method can be used to determine the working length with clinically acceptable accuracy. It was proven that the major apical foramen can be determined more accurately than the minor foramen.

Irregular orofacial functions and morphologic traits of malocclusion in children were clinically evaluated. Posterior crossbite at 5 years of age was found in 20% of the children. The relationship with incorrect orofacial functions was observed. Every clinical examination of children in the deciduous dentition with sucking habits should include assessment of orofacial functions, especially the swallowing pattern, which was found to be an important factor in the etiology for posterior crossbite development.

The aim of this study was to assess facial asymmetry and palatal volume in two groups of children, one with a unilateral crossbite (CB) and the other with no crossbite (NCB). The faces and dental casts of the children were scanned using a three-dimensional laser scanning device at baseline and after six months of treatment. Treatment of a CB in the primary dentition corrected the facial asymmetry, particularly the lower part of the face. The palatal volume of the CB children increased as a result of orthodontic intervention to similar levels exhibited by the NCB children.

With relative densitometric analysis we objectively confirm the spontaneous bone healing of big bone defects. Also the parameters of important influence of that healing were established like age of patients and the shape of bone defects.

We established that the immune response in periapical granulamas (chronical periapical parodontitis) and radicular cysts influence on development of that inflammatory lesions. We confirmed our hypothesis that immune parameters influence on development of inflammatory cysts in correlation with characteristical immune response of different bacteria. Our results lead to further hypothesis like what bacteria condition the etiology of inflammatory cysts from the nonspecific chronical inflammatory tissue like periapical granuloma.
