    Apically extruded debris associated with protaper next, protaper gold and trunatomy systems: An in vitro study
    (Tabriz University of Medical Sciences, 2021) Çirakoglu, N.Y.; Özbay, Y.
    Background. This research aimed to investigate and compare the amount of apically extruded debris after root canal preparation using ProTaper Next, ProTaper Gold, and TruNatomy systems. Methods. Forty-five extracted mandibular premolar teeth with single canals with similar lengths were used. The root canals were prepared using ProTaper Next (Dentsply Maillefer, Ballaigues, Switzerland), ProTaper Gold (Dentsply Maillefer, Ballaigues, Switzerland), or TruNatomy (Dentsply Maillefer, Ballaigues, Switzerland) files. Apically extruded debris during preparation was gathered into preweighed Eppendorf tubes. Then the Eppendorf tubes were incubated at 70°C for five days. The Eppendorf tubes were weighed again to determine their final weight plus the extruded debris. Results. The TRN system resulted in significantly less debris extrusion than the PTN system (P < 0.05). There was no significant difference between the PTN and PTG groups and between the PTG and TRN groups (P > 0.05). Conclusion. All the instrumentation systems caused apical extrusion of debris. However, the TRN system resulted in significantly less debris extrusion than the other systems. © 2021 The Author(s).

    Evaluation of apical crack formation associated with root canal preparation with ProTaper Next, ProTaper Gold, and TruNatomy systems
    (Wolters Kluwer Medknow Publications, 2021) Çirakoglu, N.N.Y.; Özbay, Y.
    Aim: The present study aimed to evaluate and compare the microcrack formation in apical root dentin as a result of root canal preparation with different nickel-titanium (NiTi) rotary systems. Materials and Methods: Sixty extracted mandibular premolar teeth with single canals were used. Apical 1 mm of roots was flattened perpendicular to the tooth axis. Forty-five teeth were prepared using ProTaper Next (PTN), ProTaper Gold (PTG), or TruNatomy files. Fifteen teeth were left unprepared as the negative control group. Images of apical surfaces of roots were obtained using a stereomicroscope at × 20 magnification. The presence of microcracks was noted with the help of the images. The data were analyzed with a Chi-square test using MiniTab 17 Statistical Software. Results: There was a statistically significant difference between the PTN and TruNatomy groups (P < 0.05). There was no statistically significant difference between the PTG group and other groups (P > 0.05). Conclusion: Whereas all rotary files created microcracks in the apical root dentin, TRN caused fewer microcracks than other NiTi rotary systems. © 2021 Endodontology. All rights reserved.

    Protective and Preventative Factors in Struggling with Addiction: The Role of Life Skills
    (AVES, 2019) Özbay, Y.; Büyüköztürk, S.; Tomar, I.H.; Esici, H.; Aliyev, R.; Yancar, C.; Kurnaz, Z.
    Drug addiction plays an important role in the problems experienced by children and adolescents in developmental risk groups. The programs developed to prevent drug addiction seem to be more on knowledge level. The aim of this study is to determine the relationship between drug addiction and life skills in adolescents. In this context, a qualitative research has been conducted in order to demonstrate the attitudes of young people and their families towards substance use/dependence, the motivations of considering and starting narratives, the reasons of starting to drug, the consequences of drug use and the importance of life skills in preventing drug addiction. The data were gathered from 10 separate interviews with a total of 87 people, consisting of parents (45) and young people (42) with the focus group interviews. The data were analyzed with qualitative data analysis technique using MAXQDA program. As a result of the research, it is found that young people who use drugs have problems with their families, do not have good relations with their families and friends, and they have low school achievement and school loyalty. Among the life skills that young people believe to be effective in preventing drug use are social skills, communication and nurturing relationships in affective domain;, problem solving, resistance to substance and goal setting, health in the field of managing emotions and self-discipline are the most important ones in cognitive domain. © 2019, AVES.
