    This study evaluated the effect of tooth preparation method (diamond bur vs. Er:YAG laser) on the microleakage levels of glass ionomers and resin composite. Human permanent premolars (N = 80) were randomly divided into two groups (n = 40). Cavities on half of the teeth were prepared using diamond bur for enamel and carbide bur for dentin and the other half using Er: YAG laser. The teeth were randomly divided into four groups according to the restoration materials, namely (a) ChemFil Rock (CFR), (b) IonoluxAC (IAC), (c) EQUIA system (EQA) and one resin composite (d) AeliteLS (ALS) (n = 10 per group). Microleakage (mu m) was assessed at the occlusal and gingival margins after dye penetration (0.5% basic fuchsine for 24 h). On the occlusal aspect, while the cavity preparation types significantly affected the microleakage for CFR (p = 0.015), IAC (p = 0.001) glass ionomer restorations, it did not show significant effect for glass ionomer EQA (p = 0.09) and resin composite ALS (p = 0.2). Er: YAG laser presented less microleakage compared to bur preparation in all groups except for EQA. On the gingival aspect, microleakage decreased significantly for CFR (p = 0.02), IAC (p = 0.001), except for EQA where significant increase was observed (p = 0.001) with the use of Er: YAG laser. Microleakage decrease was not significant at the gingival region between diamond bur and Er: YAG laser for ALS (p = 0.663). At the occlusal and gingival sites in all groups within each preparation method, microleakage level was not significant.

    Clinical Evaluation of a Fissure Sealant Placed by Acid Etching or Er: YAG Laser Combined with Acid Etching
    (QUINTESSENCE PUBLISHING CO INC, 2017) DURMUŞ, BAŞAK; Durmus, Basak; Giray, Figen Eren; Peker, Sertac; Kargul, Betul
    Purpose: To evaluate the efficacy of conventional acid etching alone (acid etching) and Er:YAG laser combined with acid etching (laser + acid etching) on fissure sealant (FS) retention of first permanent molars (FPMs) after 18 months. Materials and Methods: Using a split-mouth design in 51 children, a total of 204 FPMs were sealed with acid etching alone or laser plus acid etching (laser+acid). The retention of sealants and occurrence of caries were evaluated at 3, 6, 12, and 18 months. Statistical analysis was performed using Pearson's chi-squared tests. Results: The retention rate for FS in the laser+acid group was significantly higher than that of the acid-etch group at 12 (p = 0.0161) and 18 (p = 0.0227) months. Six FSs in the acid group and five FSs in the laser+acid group were completely lost after 18 months. The incidence of caries in the acid-etch group was 22% (n = 18) vs 10% (n = 8) in the laser+acid group at 18 months. The difference in caries development between the groups was not significant (p > 0.05). Conclusions: As enamel pretreatment, Er: YAG laser combined with acid etching significantly improves FS retention over conventional acid etching alone.
