    Shear bond strengths of different adhesive systems to white mineral trioxide aggregate
    (Japanese Soc Dental Materials Devices, 2009) Bayrak, Şule; Sen Tunç, Emine; Saroğlu, Işıl; Eğilmez, Türkan
    This study was conducted to compare the shear bond strengths of different adhesive systems to White Mineral Trioxide Aggregate (WMTA). To this end, 40 cylindrical acrylic blocks with a hole in the middle measuring 4 mm diameter X 2 mm height were prepared. The hole was filled with WMTA, and the specimens were allocated into four groups: Group 1 Prime & Bond NT; Group 2 - AdheSE; Group 3 - Xeno III; and Group 4 - Adper Prompt L-Pop. In each group, a different adhesive system and a compomer (Dyract AP) were applied over WMTA. Shear bond strengths were measured using a universal testing machine, and then the data were subjected to one-way ANOVA and Scheffe's post hoc test (p < 0.05). Significantly lowest shear bond strength value was obtained with Adper Prompt L-Pop, whereas Prime & Bond NT revealed higher shear bond strength than the others (p < 0.05). In conclusion, an etch-and-rinse adhesive system which exhibited significantly higher shear bond strength than self-etch adhesive systems - could be a preferred choice when placing compomer materials upon WMTA.

    Spontaneous re-eruption of intruded permanent incisors: five case reports
    (Mosby-Elsevier, 2006) Saroğlu, Işıl; Sen Tunç, Emine; Sönmez, Hayriye
    This report presents 5 cases of intrusive luxation in immature permanent central incisors. The intruded incisors, with careful monitoring, were allowed to spontaneously re-erupt, which avoided the need to reposition the tooth either orthodontically or surgically. All of the teeth re-erupted spontaneously in a few months. The root development continued in all of the cases and all pulps remained vital. There were no other signs of pulpal and/or periapical pathology. It can be concluded that intruded immature permanent teeth can spontaneously re-erupt, conserve their vitality, and continue their root development without any surgical or orthodontic management.
