Correlation of fillings on the tooth and changes in the tissues having direct contact with the tooth aroused keen interest amongst many professionals. Irregularly shaped fillings can damage the periodontal tissues. The primary indicator of the validity of the dental work is its ability to ensure the preservation of normal physiological status of the tissue, primarily gingival, alveolus and periodontum. The main purpose of this paper is to make histological assessments of the tissue of the interdental region before and after correction of irregular filling in experimental animals. The research was conseived as a histiological study with experimental animals ( rabbits). The tested teeth were divided into two groups: a) the experimental group consisted of teeth with irregular fills, and b)the control group consisted of teeth with regular fillings and healthy teeth. The experiment carried out under general anesthesia. The experiment was being monitored over 12-month period. Having been expired the first part of the experiment , after 6-month period, in experimental animals, it was carried out the second part of the one consisting of the correction of irregular fillings. The second part of thhe experiment was closely monitored a month, three and six months after the correction of irregular filings. After sacrificing the animals, tissue was prepared for histological analysis. Histological analysis showed changes in the periodontal tissues prior to correction of irregular fillings and significant improvementof the tissue of the interdental region after correction of the same ones. The pathological changes occuring in the periodontal tissues are not irreversible since after correction of irregular filligs are being lost mainly.

Introduction: Direct and indirect pulp capping is a therapeutic procedure to preserve the tooth's vitality. The aim was to scan electron and polarization microscopy: analyze changes in cellular and extracellular components of dental pulp after direct and indirect overlay with glass-ionomer cement (GIC), determine the appearance of the dentine surface after direct and indirect pulping overlap with GIC and forms a proposal for a clinical application of preparations if it provides good and effective dentingenesis. Methods: The experiment was performed on experimental animals (domestic swine). For this research, alkaline cement was used ALFAGAL* bejz. On the teeth of the experimental group, preparations of the V class were made from the vestibular side. Twenty-two teeth were made indirectly, and twenty –two teeth directly covered with pulp. After completion of the preparation, dentin is directly covered with glass-ionomer cement (GIC) Alfagal* bejz. Through the ALFAGAL material for definitively closing cavities (amalgam) is laid. On the teeth where the perforation of the pulp chamber was made, ALFAGAL bejz was loaded directly into the pulp chamber, and through this the cavity was definitely sealed with GIC FUJI IX (GC Japan). Suitably prepared teeth and pulp were observed by SEM and a polarization microscope. Results: By observing and analyzing the obtained results, on a polarization and scanning electron microscope compared to the control group, results were obtained which can have a significant clinical implication in the biological treatment of the pulp. Alfagalbejz is directly applied in the pulp chamber: the boundary between newly developed reparative dentine is detected in the normal dentine structure, amorphous dentine, reproduction of connective tissue cells without pro inflammatory reactions and initial dedifferentiation in odontoblast, young blood vessels and cells (fibrocytes, histiocytes and fibroblasts) are observed. Indirectly applied Alfagal* bejz indicates the presence of different maturation stages of dentin, dentinal canals are clearly visible with a normal dentin structure, zero amorphous dentine and immature dentine structure are observed as well. The presence of an amorphous calcite of the dentine structure indicates the initial creation of a solid tissue barrier, which is the goal of the experiment. Conclusion: The results obtained by experimental research suggest ALFAGAL bejz as a good material for the direct and indirect overlap of the pulp.

Teledentistry is an applied discipline of telemedicine in dentistry. In recent years, this area has been in the focus of interest of researchers. Their studies predominantly deal with the reliability of the methods of teledentistry and their feasibility in various conditions and situations. The studies based on photography and communication of visual information via smart mobile phones have been especially popular. This paper represents a review of the studies about teledentistry published in the last several of years, discuss them and puts forward the recommendations for future research.
