    Cytotoxicity of Different Nano Composite Resins on Human Gingival and Periodontal Ligament Fibroblast Cell Lines: An In Vitro Study
    (MDPI, 2020-03-01) YILMAZ GÖLER, AYŞE MİNE; Kavuncu, Gamze; Yilmaz, Ayse Mine; Yilmaz, Betul Karademir; Atali, Pinar Yilmaz; Altunok, Elif Cigdem; Kuru, Leyla; Agrali, Omer Birkan
    The aim of this study is to determine the cytotoxicity of three different nano composite resins (CRs) on human gingival fibroblast (hGF) and periodontal ligament fibroblast (hPDLF) cell lines. These CRs selected were nanohybrid organic monomer-based Admira Fusion (AF), nanohybrid Bis-(acryloyloxymethyl) tricyclo [5.2.1.0.sup.2,6] decane-based Charisma Topaz (CT), and supra nano filled resin-based Estelite Quick Sigma (EQS). MTT assay was performed to assess the cytotoxicity of CRs at 24 h and one week. AF and EQS applied on hGF cells at 24 h and one week demonstrated similar cytotoxic outcomes. Cytotoxicity of CT on hGF cells at one week was higher than 24 h (p = 0.04). Cytotoxicity of CT on hGF cells was higher at 24 h (p = 0.002) and one week (p = 0.009) compared to control. All composites showed higher cytotoxicity on hPDLF cells at one week than the 24 h (AF; p = 0.02, CT; p = 0.02, EQS; p = 0.04). AF and EQS demonstrated lower cytotoxicity on hPDLF cells than the control group at 24 h (AF; p = 0.01, EQS; p = 0.001). CT was found more cytotoxic on hPDLF cells than the control (p = 0.01) and EQS group (p = 0.008) at one week. The cytotoxicity of CRs on hGF and hPDLF cells vary, according to the type of composites, cell types, and exposure time.

    Periodontal treatment in a generalized severe chronic periodontitis patient: A case report with 7-year follow-up
    (2015-04) AĞRALI, ÖMER BİRKAN; Agrali, Omer Birkan; Kuru, Bahar Eren
    The aim of the periodontal treatment is to provide healthy and functional dentition all through a lifetime. In this report, periodontal treatment of a 42‑year‑old male patient with generalized severe chronic periodontitis is presented. He received initial periodontal treatment together with adjunctive antimicrobials. The devital teeth were endodontically treated, and free gingival grafts were placed at the inadequate keratinized tissue zones before regenerative surgery. Following the surgical treatment using enamel matrix derivatives and xenogenic bone graft combination, the patient was put on a strict recall program. After 12 months, favorable clinical and radiographical improvements were obtained. The 7‑year maintenance of the present case with several initially hopeless teeth has been shown and discussed in this report. It can be concluded that optimum oral hygiene level as well as the positive cooperation of the patient enhanced the success of periodontal treatment results even in extremely severe periodontal destruction.

    Evaluation of gingival crevicular fluid transforming growth factor-1 level after treatment of intrabony periodontal defects with enamel matrix derivatives and autogenous bone graft: A randomized controlled clinical trial
    (MEDKNOW PUBLICATIONS & MEDIA PVT LTD, 2016) YARAT, AYŞEN; Agrali, O. B.; Kuru, B. E.; Yarat, A.; Kuru, L.
    Aim: The present study aimed to evaluate the effects of enamel matrix derivatives (EMD) either alone or combined with autogenous bone graft (ABG) applied to intrabony defects in chronic periodontitis patients on clinical/radiographic parameters and gingival crevicular fluid (GCF) transforming growth factor-1 (TGF-1) level and to compare with open flap debridement (OFD). Materials and Methods: A total of 30 deep intrabony defects in 12 patients were randomly treated with EMD + ABG (combination group), EMD alone (EMD group), or OFD (control group). Clinical parameters, including plaque index, gingival index, bleeding on probing, probing depth, relative attachment level, and recession were recorded at baseline and 6 months postsurgery. Intrabony defect fill percentage was calculated on the standardized radiographs. TGF-1 level was evaluated in GCF just before surgery and 7, 14, 30, 90, 180 days after surgery using enzyme-linked immunosorbent assay. Results: All treatment procedures led to significant improvements at 6 months (P 0.01). Gain in attachment level (P 0.01) and radiographic defect fill (P 0.05) of the combination and EMD groups were found to be significantly higher than those of the control group, while the use of EMD either with ABG or alone was observed to produce significantly less recession than the OFD (P 0.05). Conclusion: The findings suggest no clinical and radiographic differences between the combination and EMD groups whereas GCF TGF-1 level demonstrates an increase during the healing phase and is positively affected from EMD.

    (2014) DOĞAN, BAŞAK; Yavuz, Atacan; Ağralı, Omer Birkan; Calışkan, Zeynep Lale; Türkaydın, Dilek; Sertgöz, Atilla; Kuru, Bahar; Doğan, Başak
    Radiotherapy in NPC patients has side effects on the dentition, which affects quality of life dramatically. This case report presents multidisciplinary dental treatment approach in a 17-year-old male patient with a history of nasopharyngeal carcinoma (NPC), which was treated with chemotherapy and radiotherapy. The adolescent patient applied to dental hospital 4 years after the radiotherapy with aesthetic and functional problems on dentition affecting psychological, social, and physical aspects of his life. The dentition of the patient demonstrated the severe destruction as a devastating side effect of radiotherapy. With a successful multidisciplinary approach, our patient's aesthetics, function, and self-confidence were obtained. Well-established procedures, which include preventative care and maintenance, can reduce the duration and expenses of the treatment and help in challenging the life-long complications of radiotherapy.

    Peri-implantitis and Severity Level
    (2020-02) KURU, LEYLA; Elemek, Eser; Agrali, Omer Birkan; Kuru, Bahar; Kuru, Leyla
    Abstract Objectives Different diagnostic criteria were used for diagnosis of peri-implant diseases. The aim of this cross-sectional study was to explore prevalence of peri-implant diseases and subclassify peri-implantitis based on different levels of radiographic and clinical findings. Materials and Methods Two hundred patients having 655 dental implants were included in this study. In addition to clinical measurements, standard long-cone parallel technique was used to evaluate marginal bone level around implants. Following diagnosis of peri-implant diseases, peri-implantitis was further subclassified using a severity leveling in terms of marginal bone level and probing depth. Results Mean age of 200 subjects was 52.8 ± 12.2 years and 63% were females. In total, bleeding on probing was present in 93% and suppuration in 27% of implants. On subject basis, 2.5% were diagnosed as healthy, 28% with peri-implant mucositis (PM), and 69.5% with peri-implantitis, whereas on implant basis, 3.6% were healthy, 36% presented PM, and 60.4% peri-implantitis. Furthermore, when severity leveling was applied, peri-implantitis prevalence changed markedly and ranged from 14.5 to 31.0% at the subject level and from 10.0 to 22.0% at the implant level. Subgingival restoration margins were observed in 70.6% of patients for implants with PM and in 44% patients for implants with peri-implantitis. Most of the implants with peri-implantitis were with platform match (71.5%). Conclusions Applying different thresholds to the peri-implantitis definition yielded different prevalence rates ranging from 10 to 31%. As no established diagnostic criteria are being used today, results from clinical studies may not reflect the true disease prevalence.
