Contemporary skull development - palatal angle analysis.

OBJECTIVES: The palatal angle is an important angle of the craniofacial complex. It is significant for the diagnosis of craniofacial disorders mainly for nasopharyngeal soft-tissue patterns.Background The dentists and otorhinolaryngologists use this relationship to establish proper treatment mechanics and evaluate facial profile. The aims of this study were to provide comparative cephalometric analyses of historical and contemporary skulls. MATERIALS AND METHOD: A total of 190 cephalograms of 2 groups of subjects were evaluated. Dolphin Imaging 11.0 - Cephalometric Tracing Analysis was used for the analysis. Unpaired two-tailed t-test assuming equality of variances was used for all variables (at the significance level p = 0.0001). RESULTS: The -modern forensic skulls had larger palatal angle at average value of 8.60 degrees ± 4.35, than that of archeological ones, the average value of which was 6.50 degrees ± 3.92. The difference was found significant. Unpaired two-tailed t-test assuming equality of variances showed that historical and contemporary skulls had statistically significant results. The difference was -2.09 with standard error of 0.60 (95% confidence interval from -3.29 to -0.89). Two-tailed probability attained value of P was less than 0.0001. CONCLUSION: The difference between both groups was found significant. An increase in the palatal angle can be directly connected with anterior rotation of upper jaw(Tab. 2, Fig. 5, Ref. 19).

Forensic dentistry--identification from the dentist's point of view.

The paper deals with an identification of missing persons based on a dental documentation. The procedure of the identification is presented in two case reports with a new possibility of electronic imaging called Dental Cross in comparison with classical dental documentation, which is officially used for identification of the missing persons by Interpol.

Electronic health record for forensic dentistry.

OBJECTIVES: To identify support of structured data entry for electronic health record application in forensic dentistry. METHODS: The methods of structuring information in dentistry are described and validation of structured data entry in electronic health records for forensic dentistry is performed on several real cases with the interactive DentCross component. The connection of this component to MUDR and MUDRLite electronic health records is described. RESULTS: The use of the electronic health record MUDRLite and the interactive DentCross component to collect dental information required by standardized Disaster Victim Identification Form by Interpol for possible victim identification is shown. CONCLUSIONS: The analysis of structured data entry for dentistry using the DentCross component connected to an electronic health record showed the practical ability of the DentCross component to deliver a real service to dental care and the ability to support the identification of a person in forensic dentistry.

[Demonstration of amyloid using histological methods]. / Prukaz amyloidu histologickými metodami.

The authors present their personal experience with common histological methods for amyloid demonstration. For practical use, they recommend staining with Congo Red followed by differentiation in alkaline alcohol and another method using staining with a 2% solution of Saturn Red in 1% NaCl. The latter method permits to differentiate between amyloid and hyalin without employing polarized light.
