    Objective. The aim of this study was to evaluate the effect of different surface treatments on the microtensile bond strength (mTBS) and shear bond strength (SBS) of resin-modified glass ionomer cement (RMGIC) to dentin. Materials and methods. Fifty-two extracted human molars were flattened to obtain dentin surfaces. For SBS assessment 40 teeth were divided into four groups according to their surface treatments (acid etching, Er: YAG laser QSP mode, Er: YAG laser MSP mode and control-SiC) (n = 10). A plastic cylinder was placed over the differently treated dentin surfaces and RMGIC was placed into the rings and polymerized. Twelve teeth were used for the mu TBS test. The treated dentin surfaces described above were restored with 4 mm high RMGIC and light cured; then, the specimens were sectioned into serial sticks (n = 15) and mu TBS and SBS were tested for failure in a testing machine with a 1 mm/min crosshead speed. The data were analyzed by one-way ANOVA and Tukey HSD tests (alpha = 0.05). Results. Acid etching showed significantly higher SBS than the other groups (p < 0.05). Er: YAG QSP and MSP-treated groups showed higher SBS values than the control group, but the difference was not statistically significant (p > 0.05). Er: YAG MSP showed the highest mu TBS value followed by acid etching, whereas the control group exhibited the lowest value (p < 0.05) and the differences between the control group and Er: YAG QSP were not significant (p > 0.05). Conclusions. The application of Er: YAG MSP mode and acid etching to dentin can be used for improving the bond strength of RMGIC.

    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.

    Treatment of post-orthodontic white spot lesions with CPP-ACP paste: A three year follow up study
    (Japanese Soc Dental Materials Devices, 2017) Karabekiroolu, Said; Unlu, Nimet; Kucukyilmaz, Ebru; Sener, Sevgi; Botsali, Murat Selim; Malkoc, Siddik
    To determine the efficacy of topical applications of 10% casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) paste in reverting white spot lesions (WSLs) after fixed orthodontic treatment. Forty one participants were randomly assigned to either the test group (CPP-ACP) or the control group (only fluoride toothpaste). All patients used regular fluoride-containing toothpaste. CPP-ACP paste or fluoridated toothpaste was applied on to tooth surfaces with WSLs twice a day during 36-month after de-bonding. The labial/buccal surfaces of teeth were assessed by use of DIAGNOdent pen (DD), Gorelick Index and ICDAS II criteria at baseline (T1) and 36-month (T2) follow-up visits. The total counts of Streptococcus mutans and Lactobacillus were obtained at T1 and T2. DMFT, DMFS, stimulated flow rate and buffer capacity were calculated in two appointments. Daily usage of CPP-ACP paste was not better than normal care for improving the appearance of WSLs after 36 months.
