This study aimed to compare polishing systems on color stability, surface roughness, and gloss of additively manufactured permanent and conventional resin composites. Totally 250 disc specimens (6 mm*2 mm) were prepared from resin-based materials [G-ænial Posterior (GP), Clearfil Majesty Esthetic (CME), SonicFill-2 (SF), Tescera (Tes), and Crowntec (CT)]. Following baseline color (ΔE00), gloss (GU), and surface roughness (Ra) measurements, the specimens were randomly divided into 5 groups (n= 10/group) according to polishing systems: Control (mylar strips); OneGloss; OneGloss + Platina Hi-Gloss; OptiDisc; and OptiDisc + Platina Hi-Gloss. Specimens were immersed in coffee for 144 h following polishing. ΔE00, GU, and Ra measurements were repeated. Atomic force microscopy images were taken in...

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, Spea...

This study aimed to evaluate the potential use of resveratrol on bone healing after tooth extraction in zoledronic acid-treated rats. Seventy-two Wistar rats were separated into 4 groups of 18: no drugs (control group), zoledronic acid (ZA), resveratrol (RES), zoledronic acid + resveratrol (ZA + RES). The first and second molars of each rat were extracted and nine rats from each group were sacrificed on days 14 and 28. The extraction sites and blood samples were analyzed histologically, immunohistochemically and biochemically. The epithelization, connective tissue, new bone formation in RES group was significantly higher compared to ZA and ZA + RES groups on day 28. The connective tissue in control group was significantly higher compared to ZA and ZA + RES groups on days 14 and 28. BMP-4 l...
