    Evaluation of temperature changes in the pulp chamber during polymerization of light-cured pulp-capping materials by using a VALO LED light curing unit at different curing distances
    (JAPANESE SOC DENTAL MATERIALS DEVICES, 2014) Savas, Selcuk; Botsali, Murat S.; Kucukyilmaz, Ebru; Sari, Tugrul
    The aim of this study was to evaluate temperature changes in the pulp chamber during polymerization of four different pulp-capping materials using a LED-light-curing-unit in the contact and noncontact positions. A pulpal circulation mechanism was simulated to measure increases in temperature in four pulp-capping materials that were applied to the occlusal dentin surface. Two different distances were used between the tip of the unit and the material surface during polymerization; 0 and 2 mm. The data were statistically analyzed using factorial-ANOVA, one-way-ANOVA, and Tukey's HSD test. There were statistically differences between contact and noncontact groups (p<0.05). Contact groups produced significantly lower temperature rise compared with noncontact groups. The highest and lowest mean temperature increases were calculated for the Biner LC and the TheraCal LC, respectively. Considering the effects of temperature rising, the distance of the light curing units from restorations should not be overlooked as well as the types of the materials.

    Periostitis Ossificans Managed with Endodontic Treatment
    (AMER SOC DENTISTRY CHILD, 2015) Kucukyilmaz, Ebru; Sener, Yagmur; Tosun, Gul; Savas, Selcuk
    Periostitis ossificans (PO) is a specific type of chronic osteomyelitis. Radiographically, it is characterized by the presence of lamellae of newly formed periosteal bone outside the cortex, giving the characteristic appearance of "onion skin." The most common cause of PO is periapical infection of the mandibular permanent first molar, which occurs primarily in children and young adults. Treatment in these cases is directed toward eliminating the source of the infection, either by extraction of the offending tooth or endodontic therapy. The purpose of this paper is to present a case of PO involving a permanent mandibular first molar managed with endodontic treatment.
