Preformed stainless steel crowns are used in pediatric dentistry to obtain full crown restoration of primary molar teeth. They are consider the best restoration in terms of durability and effectiveness. The purpose of this study is to evaluate microbial, cytological and physio-chemical properties to determine whereas stainless steel crown are biocompatible, safe for surrounding tissue and helpful in avoiding micro-organisms influence on the tooth tissue. Based on the results, it was determined that stainless steel crowns used in pediatric dentistry represent no cytotoxic risk to the surrounding tissues, have a low probability of developing hypersensitivity to the coronal material and also that their biological properties make them suitable to use in pediatric dentistry for the reconstruction of damaged primary molar tissue.

The basic form of pollution is characterized by a microscopic size and solid state and it is called particulates or particulate matter. Unfortunately, these forms undergo a variety of transformations, which consequently can sometimes be easily modified and even cause an increase in their toxicity. This work was devoted to join the composition of various materials being residues after different combustion processes with the distribution of elements and molecules within studied surfaces. The content of chosen elements was determined using ICP-MS and ICP-OES methods. Elemental and/or molecular distribution was studied using surface sensitive techniques, SEM-EDS and ToF-SIMS. The obtained results revealed that the composition and morphology of particles are strongly influenced by the type of material and combustion conditions.
