Öğe Antibacterial and Smear Layer Removal Efficacy of Er:YAG Laser Irradiation by Photon-Induced Photoacoustic Streaming in Primary Molar Root Canals: A Preliminary Study(Mary Ann Liebert, Inc, 2018) Korkut, Emre; Torlak, Emrah; Gezgin, Onur; Ozer, Hazal; Sener, YagmurObjective: The objective of this study was to compare antibacterial and smear layer removal efficacy of the erbium:yttrium-aluminium-garnet (Er:YAG) laser irradiation by photon-induced photoacoustic streaming (PIPS), neodymium:yttrium-aluminium-garnet (Nd:YAG), and diode lasers and conventional irrigation agent in primary molar root canals. Background: The selection, application, and activation of the irrigant are important factors affecting the success of the endodontic treatment. Materials and methods: Distal root canals of human primary mandibular molar teeth used for antimicrobial efficacy evaluation were first inoculated with Enterococcus faecalis (n=25). Smear layer removal efficacy was evaluated on the noninoculated specimens (n=20). The root canals in the first treatment groups were irrigated with a conventional technique using 5% sodium hypochlorite (NaOCl). In the laser groups, the root canals were irradiated with either Nd:YAG (1064nm) or diode lasers (940nm) followed by NaOCl irrigation agent. In the fourth groups, the NaOCl irrigation agent was activated with an Er:YAG laser (2940nm) by PIPS tip using nonablative settings. Antibacterial efficacy was determined by viable counts of E. faecalis after treatments. The treated root canals were examined by scanning electron microscopy to determine the smear layer removal efficacy of treatments. Results: Statistically significant (p<0.05) reductions in the number of E. faecalis were achieved in Nd:YAG and diode laser groups and Er:YAG laser by PIPS-activated irrigation groups compared to the NaOCl group. Er:YAG laser by PIPS-activated irrigation resulted in more cleaning of the root canal walls and a higher quantity of open tubules. Conclusions: These findings suggest that Er:YAG laser by PIPS-activated irrigation can be considered as an effective irrigant agitation technique in pediatric endodontics.Öğe Antimicrobial and mechanical properties of dental resin composite containing bioactive glass(Wichtig Publishing, 2016) Korkut, Emre; Torlak, Emrah; Altunsoy, MustafaBackground: The aim of this study was to evaluate the antimicrobial efficacy and mechanical properties of dental resin composites containing different amounts of microparticulate bioactive glass (BAG). Methods: Experimental resin composites were prepared by mixing resin matrix (70% BisGMA and 30% TEG-DMA) and inorganic filler with various fractions of BAG to achieve final BAG concentrations of 5, 10 and 30 wt%. Antimicrobial efficacy was assessed in aqueous suspension against Escherichia coli, Staphylococcus aureus and Streptococcus mutans and in biofilm against S. mutans. The effect of incorporation of BAG on the mechanical properties of resin composite was evaluated by measuring the surface roughness, compressive strength and flexural strength. Results: Under the dynamic contact condition, viable counts of E. coli, S. aureus and S. mutans in suspensions were reduced up to 78%, 57% and 50%, respectively, after 90 minutes of exposure to disc-shaped composite specimens, depending on the BAG contents. In 2-day-old S. mutans biofilm, incorporation of BAG into composite at ratios of 10% and 30% resulted in 0.8 and 1.4 log reductions in the viable cell counts compared with the BAG-free composite, respectively. The surface roughness values of composite specimens did not show any significant difference (p>0.05) at any concentration of BAG. However, compressive and flexural strengths of composite were decreased significantly with addition of 30% BAG (p<0.05). Conclusions: The results demonstrated the successful utilization of BAG as a promising biomaterial in resin composites to provide antimicrobial function.Öğe Biofilm formation by Staphylococcus aureus isolates from a dental clinic in Konya, Turkey(Elsevier Science London, 2017) Torlak, Emrah; Korkut, Emre; Uncu, Ali T.; Sener, YagmurThe ability of Staphylococcus aureus to form biofilm is considered to be a major virulence factor influencing its survival and persistence in both the environment and the host. Biofilm formation in S. aureus is most frequently associated with production of polysaccharide intercellular adhesion by ica operon-encoded enzymes. The present work aimed at evaluating the in vitro biofilm production and presence of the icaA and icaD genes in S. aureus isolates from a dental clinic in Konya, Turkey. The surfaces of inanimate objects were sampled over a period of six months. S. aureus isolates were subjected to Congo Red Agar (CRA) and crystal violet (CV) staining assays to evaluate their ability of biofilm production, while the presence of the icaA and icaD genes was determined by polymerase chain reaction. S. aureus contamination was detected in 13.2% of the environmental samples. All the 32 isolates were observed to be positive for both the icaA and icaD genes. Phenotypic evaluations revealed that CV staining assay is a more reliable alternative to CRA assay to determine biofilm formation ability. A high percentage of agreement (91%) was observed between the results from CV staining and ica genes' detection assays. Phenotypic and genotypic evaluations should be combined to detect biofilm formation in S. aureus. Our findings indicate that dental clinic environments should be considered as potential reservoir for biofilm-producing S. aureus and thus cross contamination. (C) 2017 The Authors.

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.Öğe Effect of Passive Tobacco Smoking Exposure on the Periodontal Status of Turkish Children(Univ Indonesia, Fac Dentistry, 2021) Alan, Raif; Gezgin, Onur; Korkut, Emre; Turkoglu, Sukriye; Celik, Esra; Haliloglu, SeyfullahObjective: This study aimed to assess the effect of passive tobacco smoking (PTS) through the comparison of the periodontal status and the C-reactive protein (CRP) and cotinine levels in the biologic fluids in children who are exposed and unexposed to PTS. Methods: A total of 148 participants, whom had smokers (PTS-exposed, n=82) and non-smokers (PTS-unexposed, n=66) in their families, respectively, were included in the study. Gingival index, plaque index, probing depth, and bleeding on probing were recorded. Moreover, saliva, urine, and gingival crevicular fluid samples were collected. CRP and cotinine levels in the biological fluids were determined by the enzyme-linked immunosorbent assay method. Results: Both groups exhibited similar values for periodontal parameters and salivary CRP levels were higher in PTS-exposed group but not significant. The mean urinary cotinine level was significantly higher in children exposed to PTS than in unexposed children. Conclusions: There was no evidence for causative role of PTS in periodontal disease in this study. Longitudinal studies including large populations should be conducted to provide stronger evidence for the causative role of PTS in periodontal disease. Also, further epidemiological studies on the social context of smoking should be performed to improve the quality of life and lifespan of the society.Öğe Effect of Passive Tobacco Smoking Exposure on the Periodontal Status of Turkish Children(Univ Indonesia, Fac Dentistry, 2021) Alan, Raif; Gezgin, Onur; Korkut, Emre; Turkoglu, Sukriye; Celik, Esra; Haliloglu, SeyfullahObjective: This study aimed to assess the effect of passive tobacco smoking (PTS) through the comparison of the periodontal status and the C-reactive protein (CRP) and cotinine levels in the biologic fluids in children who are exposed and unexposed to PTS.

The pain that occurs during theuse of caries removal instruments has a strong potentialof triggering dental anxiety and fear in most children andadults. This study aimed to evaluate and compare the painperceptions of children who underwent caries removal viaan Er:YAG laser and traditional rotary instruments.MATERIALS AND METHOD: Occlusal caries was removed fromthe permanent molar teeth of 120 pediatric patients whoreferred to the Department of Pediatric Dentistry, Facultyof Dentistry, Necmettin Erbakan University, usingan Er:YAG laser and high- and low-speed rotary instruments.All restorative procedures were performed by oneclinician. The participant children were asked to choose avalue or figure from the Wong-Baker FACES Pain RatingScale, and the data were analyzed using the Wilcoxon test(?0.05).RESULTS: A statistically significant difference was foundbetween the groups (p0.05). In the Er:YAG laser group,20.83% of the participants, and in the conventional group,6.66% of the participants selected the option ‘no hurt’.The option ‘hurts worst’ was selected in neither of thegroups.CONCLUSION: The use of Er:YAG laser for caries removalcauses less or no pain during the operations, comparedto traditional rotary instruments. Therefore, it can be arguedthat Er:YAG laser is a more comfortable and acceptablealternative for pediatric patients.Öğe Evaluation of temperature changes in the pulp chamber during polymerization of pulp capping materials(Taylor & Francis Ltd, 2018) Korkut, Emre; Tulumbaci, Fatih; Gezgin, Onur; Ozer, Hazal; Ozcan, MutluPolymerization of resin-based materials leads to temperature rise, caused by the exothermic nature of the reaction and energy absorbed during polymerization. This temperature rise is influenced by intensity of light, composition of resins, and type of light source. This study evaluated thermal insulating properties of four photo-polymerizing pulp-capping agents in primary and permanent teeth. Roots of 80 primary and permanent teeth were removed. Class-I cavities were prepared on the occlusal surfaces of teeth. Materials used were TheraCal LC, Biner LC, ACTIVA BioACTIVE, and Calciplus LC and light sources were 3M-Elipar and VALO LED. Temperature rise was measured using a J-type thermocouple. Data were statistically evaluated using ANOVA and Tukey`s tests (p=0.05). VALO LED exhibited significantly lower temperature rise in all groups and temperature rise in primary teeth was significantly higher with all experimental materials (p<0.05). The highest temperature change was observed in the Biner LC group (3.82 +/- 0.58) and the lowest change in the Activa-BioACTIVE group (1.78 +/- 0.34). The VALO LED light source caused a significantly lower increase in pulpal temperature compared with the 3M-Elipar source. All tested materials and light sources maintained pulpal temperature under safe limits, with temperature increases not exceeding 5.5 degrees C.Öğe Genel Anestezi Altında Yapılan Diş Tedavilerinin Çocukların Yaşam Kalitesi Üzerine Etkisi(2017) Korkut, Emre; Gezgin, Onur; Özer, Hazal; Alan, Raif; Şener, YağmurErken çocukluk çürüğü bulunan 0-72 ay aralığındaki çocuklarda, dental işlemlerin uygulanması sırasında yaşa bağlı kooperasyon bozukluğu, anksiyete gelişmesi, işlem seanslarının uzun olması gibi sebeplerden dolayı genel anestezi yöntemi sıklıkla tercih edilmektedir.

Methods: Experimental resin composites were prepared by a resin matrix (50% BisGMA and 50% TEGDMA) and inorganic filler with BAG (5, 10 and 30%). Each resin composite was placed in the tooth cavity (n=5). After polymerisation, samples were immediately immersed in 75% ethanol and 25% deionised water (6ml) at 37 degrees C. Residual monomers (Bis-GMA, TEGDMA, HEMA and UDMA) that were eluted from the composites for 10m, 1h, 1 d, 7 d and 30 d were analysed by high-performance liquid chromatography (HPLC). The data were analysed with one-way ANOVA and Tukey HSD at a p<0.05 significance level. Results: Among the time periods, the fastest released residual monomer was observed in the 10m elution. The highest amount of released residual monomer from all groups (except the control group) was TEGDMA, whereas this was HEMA for the control group. The amounts of residual monomers eluted from BAG30 were significantly higher than other groups (p<0.05). Conclusions: The release of the monomer increases in accordance with the increased BAG addition to the composite resins.Öğe İzole oligodonti: Olgu sunumu ve iki yıllık takip(2014) Yıldırım, Yasin; Botsalı, Murat Selim; Şener, Yağmur; Korkut, EmreOligodontia is defined as the congenitally missing of six or more teeth, excluding the third molars.

During this pandemic, teledentistry (TD) could be a novel way to resume dental practice. It was aimed to investigate the satisfaction of the parents who received teledentistry (TD) service in a pediatric dentistry clinic during the COVID-19 pandemic, as well as other factors that may have contributed to this satisfaction. MethodsIt was conducted using a telephone survey to interview the parents who used the TD system between June and December 2020. The survey includes participant demographics, COVID-19 anxiety, TD system, reasons for using TD, and Internet use in the field of health. Five-point Likert scale was used. A Chi-squared test was used and p ResultsMost of the participants stated that they had no trouble connecting to the TD system (82.5%), and 119 participants reported that the system helped them to solve their health problems. Significant relationships (p < 0.05) were found between overall satisfaction and parental job, level of education, anxiety level (3 questions), and use of the Internet in healthcare (4 questions), whereas no associations were found regarding the other variables (p > 0.05). ConclusionsParents benefited greatly from the TD system and would be open to using it after the pandemic. The education and parental job categories of parents, anxiety level, and use of the Internet in healthcare seem to have relationships with overall satisfaction.
