The osteoinductive potential of different root-end filling materials in a rat femur model
Aksu, Seckin | Kucuk, Ayse Ozcan
In pediatric dentistry, the enduring success of root-end filling materials employed for the establishment of apical plugs in immature teeth undergoing endodontic intervention is contingent upon their possessing a robust osteoinductive capacity. Hence, the primary objective of this study was to histologically assess the osteoinductive potential of four distinct dental materials, specifically recommended for retrograde filling applications, utilizing an animal hard tissue model. Within the designed experimental model, two bone defects measuring 2 mm in diameter and 2 mm in depth were created in both femurs of a cohort comprising 21 male Wistar albino rats. The first defect in the right femur was left blank as the control group, and Neo MTA Plus was placed in the second defect. The EndoSequen...
Metaphorical perceptions of dental students toward dental education: a cross-sectional study from Türkiye
Aksu, Seçkin | Erturk-Avunduk, Ayse Tugba
Background Understanding the complex, multifaceted, and often subconscious emotional and cognitive perspectives of undergraduate dental students regarding their education is crucial. Personality types and stress levels are believed to play a significant role in shaping these perceptions. Employing metaphors—using a familiar and concrete concept to explain an unfamiliar or abstract one—is an effective cognitive transfer technique for exploring students’ views on dental education. This cross-sectional study aims to investigate dental students’ perceptions of their education through metaphor analysis. Additionally, it aims to examine the relationship between students’ personality types and stress levels, offering deeper insights into the factors influencing their educational experiences. Me...

Aksu, Seçkin
In recent years, esthetic expectations have come to the fore in pediatric dentistry, as in every field of dentistry. Therefore, to better meet patients’ expectations, the steps taken to determine and improve the current level of knowledge of pediatric dentists on tooth discoloration gain importance. This study aims to measure the knowledge levels of pediatric dentists regarding tooth discoloration. A 33-questioned survey created online was emailed to pediatric dentists between March and December 2021. The first part included four multiple-choice and two open-ended questions regarding demographic characteristics. The second part was to measure the participants’ knowledge of tooth discoloration. The last part was to evaluate the clinical approaches of the participants. Participants who agree...

Association between serum cytokine levels with pulp necrosis and apical periodontitis in sickle cell disease
Aksu, Seçkin
This study’s objective was to assess the relationship between serum cytokine levels and the occurrence of pulp necrosis (PN) and apical periodontitis (AP) in adolescents with Sickle Cell Disease (SCD). A total of 52 adolescents, including 29 individuals diagnosed with SCD, participated in the study. Serum cytokine levels including IL-1, IL-2, IL-4, IL-6, IL-1β, IL-8, IL-10, IL-17, and TNF-α were analyzed. Radiological and intraoral dental examinations were conducted on the same day. Electric pulp testing and cold tests were conducted on all intact crowned teeth to assess the presence of PN. Periapical index scores were derived from panoramic and periapical radiographs to identify teeth exhibiting AP. Statistical analyses were carried out using Student’s t-test, Chi-square test, Spearman co...

Shear bond strength of calcium silicate-based cements to glass ionomers
Aksu, Seckin
Background A shear bond strength between the biomaterial and restorative material is crucial for minimizing bacterial microleakage and ensuring a favorable long-term prognosis for vital pulp therapy. This study aimed to conduct a comparative evaluation of the shear bond strength between calcium silicate-based biomaterials utilized in vital pulp treatment and various glass ionomer cement materials, both with and without the application of adhesive agents. Methods A total of 270 acrylic blocks, each featuring cavities measuring 4 mm in diameter and 2 mm in depth, were prepared. Calcium silicate-containing biomaterials (ProRoot MTA, Medcem Pure Portland Cement, and Medcem MTA), following manufacturers' instructions, were placed within the voids in the acrylic blocks and allowed to set fo...
