Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2000; 100(1): 9-16
The authors describe abnormalities in the development of the cranium and soft tissues of the face in different types of facial clefts, their origin, consequences and importance for treatment.

Importance of Panoramatic Radiodiagnostics of Edentulous Maxillae and Mandibles
E. Mitrová, E. Ďurovič
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2000; 100(1): 17-22
The authors analyzed 200 panoramatic radiograms of edentulous maxillae and mandibles. They investigated the prevalence, frequency and site of pathological findings. They recorded the presence of pathological findings such as residual fragments of roots, unspecified shadows, retained teeth and light spots. The authors recorded pathological findings in 21.5 % patients. All assessed pathological findings were more frequently in distal parts of the maxilla and mandible as compared with the frontal parts. In the maxilla there were significantly more retained teeth in the mandible there were significantly more residual root fragments and other shadows. The...

Z. Broukal, J. Dušková, L. Bártová, J. Dolanský
Čes. stomatol. Prakt. zub. lék. (Czech Dental Journal) 2000; 100(1): 23-28
A group of 20 patients indicated for the replacement of impaired amalgam fillings were involved in this model study. In one session the two-surface amalgam filling to be repaired was removed and a new filling either from amalgam (Ana 2000) or from composite resin (Charisma) was inserted. Samples of saliva and urine were taken before and after treatment, and then 3, 24, 48, 96 hrs and one and two weeks after treatment. Mercury in saliva and urine was analyzed by the cold vapor mass absorption spectrophotometry. Mercury levels in salivarose during the treatment by roughly five logs (irrespective of the filling material used) whileurine mercury rose in...

Evaluating information published in scientific sources, the authors agreed on the fact that the quality of the hydroxyapatite coating is insufficiently explored and that the contemporary standard of since doesn't warrant to pronounce definitive judgement. It is necessary to take in consideration that effort to discreditation of coated implant have considerable commercial background.
