Objective: the present study aimed to investigate whether dental wear depth perception has influence on the final quality of aesthetic direct restorations in the pre-clinical setting. Material and Methods: eighty one participants were assigned to one of three groups (n=27): G1, beginning dentistry students; G2, intermediate dentistry students; and G3, advanced dentistry students. All groups were required to prepare a tooth for facet of 1mm in depth. Subsequently, teeth were restored with opaque or translucent composite resin. Results: dental wear was different among the groups (p<0.05). G1 obtained a median of 1mm, G2 obtained a median of 0.5mm, while G3 obtained a median of 0.8mm. G3 presented more consistent accuracy in dental wear. Color values did not vary according to the dental wear depth or to the type of resin composite used in the restoration (p> 0.05). Conclusion: technical training and clinical experience contribute to the better dental wear depth perception of undergraduate dental students. No direct correlation between the dental wear depth perception and the quality of shade matching of restored artificial teeth could be performed in the pre-clinical environment.

Composite Restoration

Abstract Introduction. Midline gap (diastema) is a space between two teeth, commonly between two incisors. The treatment can be provided by orthodontic, conservative (restorative) or prosthetic methods. Aim. The aim of the study was an assessment of using direct composite restoration in aesthetic closing of diastema. Material and methods. The space correction between teeth was performed among female and male adult patients with diastema of 3 to 6 mm. The microhybrid resin composite was used for the composite build-ups with a help of celluloid or silicon matrix due to its good handling properties and shade matching, and polishability properties. Results. Depending on the size of diastema, the partial or total closing was done to achieve the cosmetic effect. The obtained clinical results were highly assessed both by dentists and patients. It was possible to obtain optimal aesthetic results with resin composite restorations only. Conclusions. The simple closure of diastema with direct composite reconstructions can result in successful outcome and patient's satisfaction.

Inorganic Precursors

Cellular organic structures such as wood can be used as scaffolds for the synthesis of complex structures of organic/ceramic nanocomposites. The wood cell is a fiber-reinforced resin composite of cellulose fibers in a lignin matrix. A single cell wall, containing several layers of different fiber orientations and lignin content, is separated from its neighboring wall by the middle lamella, a lignin-rich region. In order to achieve total mineralization, deposition on and in the cell wall must be achieved. Geological fossilization of wood occurs as permineralization (filling the void spaces with mineral) and petrifaction (mineralizing the cell wall as the organic component decays) through infiltration of wood with inorganics after growth. Conversely, living plants can incorporate inorganics into their cells and in some cases into the cell walls during growth. In a recent study, we mimicked geological fossilization by infiltrating inorganic precursors into wood cells in order to enhance the properties of wood. In the current work, we use electron microscopy to examine the structure of silica formed in the cell walls after infiltration of tetraethoxysilane (TEOS).
