U literaturi su opisani neki slucajevi. U ovom je radu predstavljena izolirana pojava visestrukih prekobrojnih zuba u objema celjustima kod jedne pacijentice i njezina brata. Lijecnici su analizirali klinicke manifestacije te promjene i ucinke nastale zbog prekobrojnih zuba. Predložili su i mogucu terapiju te slucaj usporedili sa slicnim nalazima drugih autora.

The objective of the research was to obtain data on the values of salivary Streptococcus mutans and Lactobacillus spp. in 12 years old children and teenagers (13 - 18 years old children), and to compare the values of these cariogenic microoorganisms in children of various ages, for the purpose of valuating the risk of caries. The sample comprised 32 persons divided into two groups. The first group included 17 children of the age of 12. The second group included 15 teenagers. The specimen of stimulated saliva, needed for the purpose of establishing the quantities of Streptococcus mutans and Lactobacillus spp., was taken by the method of CRT-bacteria, according to manufacturers instruction. In the group of 12 years old children, the distribution of salivary Lactobacillus spp. was as follows: very low values 41,1%, low values 35,2%, high values 17,6%, very high values 5,8%, while in the group of teenagers, the results were the following: very low values 26,66%, low values 33,33%, high values 40%, very high values 0%. The levels of Streptococcus mutans were the following: 12 years old children had very low values in 41,7% cases, low values in 11,7% cases, high values in 41,7% cases, very high values in 5,8% cases, while the group of teenagers had very low values in 0%, low values in 33,3%, high values in 33,3%, and very high values in 33,3% cases. The levels of Streptococcus mutans are higher in our teenage children than in younger children, while the differences in levels of Lactobacillus spp. among children of various ages do not exist. In terms of global distribution, the levels of Streptococcus mutans and Lactobacillus spp. are higher in our population than in other countries in both control groups.

Antiresorptivni učinak intrakanalne aplikacije alendronata na eksperimentalnom modeluIntroduction The most frequent therapy used on patients with avulsed teeth is the method of replantation.Clinical and histological studies have shown that the main factors that have impact on replanted teeth are: the length of the extra-alveolar period, storage condition and maturation of the root (1,2,3). When the avulsed tooth is immediately replanted or stored in a solution capable of preserving the peri-odontal fibers attached to the root, the chances of success in replantation increase considerably (4-7).Nev-ertheless, in the majority of cases, the avulsed teeth are left exposed to a dry environment or extraalveolar for a long period of time. Thus, the treatment of the root surface and endodontic therapy of the avulsed

Introduction: In dental clinical practice, devices such as mobile phones and DSLR cameras (Digital Single Lens Reflex) are used to take intraoral and extraoral photographs. The existence of a large number of studies would allow the establishment of standards for the analysis of photographs and their wider use in daily practice in order to establish a rapid diagnosis, predictability of results and the development of teledentology during the COVID-19 pandemic. The aim of the pilot study was to determine the repeatability of point positioning in the analysis of facial symmetry in digital 2D photography. Materials and methods: One face was photographed using two different photography techniques. Points were positioned in one photo and used for each subsequent measurement. Two evaluators positioned 20 points in three time-separated periods. Results: The results suggest a relatively high degree of agreement of the point positioning provided by the two evaluators. Absolute matching of estimates was registered on 22 parameters (ICCs = 1.00), while on another 17 this value was high (ICCs >.96) Conclusion: This study shows that the values of the interclass of correlation coefficients calculated by the method of two-way random effects for each of the six indices are higher than the values of the lower limit of acceptability (ICC> 0.70). It is necessary to do additional research that will include a larger sample and different phone models to establish the diagnosis of facial asymmetry and the development of teledentistry.
