Calcium silicate-based materials are interesting products widely used in dentistry. The study was designed to compare the chemical reaction between analyzed two preparates and dentin during cavity lining. In our work, dentinal discs were prepared from human extracted teeth filled with Biodentine and MTA+. The samples were then analyzed by way of SEM, EDS and Raman spectroscopy. The obtained results revealed differences in elemental composition between both materials. Biodentine showed higher activity in contact with dentine. Moreover, the interfacial layer in the tooth filled by Biodentine was wider than that in the tooth filled with MTA+. The applied methods of analysis confirmed that both materials have a bioactive potential which is a promising ability.

Proximal surfaces are the second in turn after the occlusal surfaces, as being the most exposed places to the carious process. The specificity of changes and location makes the diagnostic of approximal cavities difficult. The aim of the study was to collect information on possibilities of detection, monitoring and assessment of carious lesions located on proximal surfaces, starting from the early stage. On the base of current literature, chosen methods of diagnosis, from conventional, to advanced technologies were presented. Current literature also suggests that none of the diagnostic methods exclude the possibility of misdiagnosis of proximal caries. Therefore, during the diagnosing of doubtful cases, it is advisable to employ several methods of assessment, with simultaneous individual appraisal of caries risk factors, such as oral hygiene, frequency of eating sweets or the number of active caries foci.

The diagnostic management is a very important and integral part of the entire treatment process and has a direct influence on the decision-taking on the choice of the most appropriate form of therapy consistent with current knowledge. Knowledge of the morphology of hard dental tissues lesions has led to the development of quantitative methods for diagnosis and monitoring of dental caries, which enabled the implementation of appropriate treatments aimed at repairing than replacing damaged tissue. The aim of the study was to compare selected diagnostic methods: visual (ICDAS), impedance spectroscopy (CarieScan PRO) and laser fluorescence (Diagnodent Pen) in detecting caries in grooves on the chewing surfaces of molars and premolars. The obtained results indicated a high concordance of measurements performed with the Diagnodent Pen with the results of visual examination and a lower compliance of visual examination with the results obtained using the CarieScan PRO. A combination of visual and tactile method with tests using advanced technology provides greater opportunity to confirm the diagnosis of carious lesions requiring medical intervention.
