Material and Methods: Thirty single-canal extracted teeth were used for the study. The root canals were prepared by using ProTaper nickel titanium rotary files. During preparation and between each file action, 1 ml of 5% sodium hypochlorite was used as an irrigant. After completion of the instrument operations all specimens received a final flush of MTAD combined with endosonic irrigation and dried with paper points. The specimens were obturated with Resilon/Epiphany SE and GuttaFlow2. All specimens were centrifuged at 3 G for 5 minutes in 2% Rhodamine B dye solution. Dye penetration was measured from the apical to the coronal part of the root canal using a stereomicroscope with an ocular micrometer. Results: GuttaFlow2 specimens showed less leakage than the Epiphany SE specimes. There is a significant difference in amount of leakage values between Epiphany SE and GuttaFlow2 groups (p<0.05). Conclusion: GuttaFlow2 filling material had higher sealing ability than Epiphany SE when the root canals were irrigated with endosonic irrigation of MTAD as a final irrigation..

Materials and methods: Fifty-six extracted premolar teeth were randomly divided into two main groups according to the presence or absence of radiotherapy. Specimens were divided into two equal groups. In the radiotherapy group, a total dose of 60 Gy was delivered with 1.8 Gy/d fractions, 5 days a week, for 35 days. The root canals were obturated with either gutta-percha/AH Plus or Resilon/Epiphany SE canal sealer. The samples were then evaluated for the coronal-sealing ability using a centrifuging dye penetration test at 3000 rpm for 5 min in a 2% Rhodamine B solution. The degree of dye penetration was evaluated with a stereomicroscope. Results: Although the sealing ability of both groups was not affected in radiotherapy, the coronal leakage values of Resilon/Epiphany SE slightly increased when radiation was applied (P > 0.05). Conclusion: Radiotherapy does not significantly affect the coronal-sealing ability of root canal obturation materials, gutta-percha/AH Plus and Resilon/Epiphany SE.

Methods: A 10 mL liquid solution was taken with syringe at 5, 10, 24, and 48 hour time intervals from freshly prepared hand-operated and automatic processing solution. The swab samples were taken from the surfaces of radiographic solution tanks, X-ray cone and its button. The specimens were inoculated into blood agar and Eosin Methylene-Blue (EMB) agar. The plates were incubated in an incubator for 48 hours at 37 °C. Becton Dickinson Phoenix Automated Microbiology System was used for determining the microorganisms. Results: Although the microbiologic analyses of the samples revealed no microbial growth in the hand-operated and automatic radiographic solutions in all observation periods, the microbial growth on the contact surfaces was observed. Staphylococcus epidermidis, metisillin resistant from the surface of radiographic solution tanks, X-ray cone and switch. Streptococcus mitis was found on the X-ray switch. Conclusion: Radiographic procedures can cause cross contamination; clinicians should therefore apply disinfection protocols in all radiographic procedures.

The 120 roots were instrumented by using the ProTaper rotary system under irrigation with 2.5% sodium hypochlorite and randomly divided into two major groups according to the final irrigation: 1.3% NaOCl + MTAD and 5% NaOCl + 17% EDTA. For controls, 10 roots from each of the final irrigations with NaOCl + MTAD and NaOCl + EDTA (20 roots) were not filled with Ca(OH)2. The intra-canal paste, Ca(OH)2 was applied to each of the 100 remaining roots and stored at 37°C for 7 days. Each group was sub-divided into five sub-groups (n = 10) according to the removal technique for the intra-canal dressing: Group-1: recapitulation with size 30 K file + 3 ml of saline solution, Group-2: recapitulation with size 30 K file + 3 ml of 5% NaOCl, Group-3: using 5% NaOCl + 17% EDTA, Group-4: using 5%NaOCl + 15% citric acid, and Group-5: using 1.3% NaOCl + 5 ml MTAD. The root canals were filled with Resilon and Epiphany SE sealer. The bond strength was measured. The mean bond strength of Epiphany SE to root dentine irrigated with NaOCl + MTAD was lower than that of NaOCl + EDTA. The highest bond strengths were 3.31 ± 0.057 and 2.60 ± 0.054 in the NaOCl + citric acid group when Ca(OH)2 was applied to roots treated with NaOCl + EDTA and NaOCl + MTAD, respectively (p &lt; 0.05). For root canals treated with NaOCl + EDTA or NaOCl + MTAD, the use of NaOCl + chelating agent for Ca(OH)2 removal does not adversely affect the bond strength of Epiphany SE to dentin.

Materials and methods: Forty primary molar teeth in 40 healthy children aged 5-9 years were treated by direct pulp capping. Teeth were randomly assigned to two groups (n=20) according to material used for capping, as follows: Group 1: calcium hydroxide cement (Dycal); Group 2: calcium sulfate hemihydrate (Dentogen). All teeth were restored with a conventional glass ionomer base (Fuji IX) and amalgam. Results: After 12 months, the overall success rate of direct pulp capping was approximately 75% (24/32 teeth, excluding exfoliations). The success rate did not differ significantly between calcium hydroxide and calcium sulfate hemihydrate treatment. Conclusion: Calcium sulfate hemihydrate was found to be as successful as calcium hydroxide for direct pulp capping of primary molars with Class I cavities. Further histological studies are needed to support these findings.
