Publication Metadata only Effect of topically applied hyaluronic acid on pain and palatal epithelial wound healing: An examiner-masked, randomized, controlled clinical trial(AMER ACAD PERIODONTOLOGY, 2018) DOĞAN, BAŞAK; Yildirim, Selin; Ozener, Hafize Ozturk; Dogan, Basak; Kuru, BaharBackground: This study aims to evaluate the effects of two different concentrations of topical hyaluronic acid (HA) on postoperative patient discomfort and wound healing of palatal donor sites after free gingival graft (FGG) surgery. Methods: Thirty-six patients requiring FGG were randomly assigned into three groups in an examiner-masked, randomized, controlled clinical trial. After harvesting palatal grafts, 0.2% and 0.8% HA gels were used in test groups 1 and 2, respectively. Gels were applied on donor sites and protected with periodontal dressing in the test groups, whereas the wound was covered only with periodontal dressing in the control group. On days 3, 7, 14, and 21, pain and burning sensation were recorded using a visual analog scale (VAS) as well as other parameters such as complete epithelization (CE) and color match on days 3, 7, 14, 21, and 42. Results: Test groups experienced less pain than the control group on days 3 and 7 (P < 0.001 and P < 0.001, respectively). Mean VAS score for burning sensation was higher in the control group on day 3 compared with test groups 1 and 2 (P = 0.03 and P = 0.02, respectively). CE in all patients was achieved on day 21 in both test groups, whereas it was achieved on day 42 in the control group. The test groups showed higher color match scores than the control group on days 21 (P < 0.001 and P < 0.001, respectively) and 42 (P = 0.004 and P = 0.002, respectively). Conclusion: Topical application of HA exhibits positive impact on postoperative pain and burning sensation, and accelerates palatal wound healing in terms of epithelization and color match.Publication Metadata only Oral squamous cell papilloma: a case report(AVES PRESS LTD, 2015) ÖZTÜRK ÖZENER, HAFİZE; Ozener, Hafize Ozturk; Kuru, Leyla; Kuru, BaharOral squamous cell papilloma (OSCP) is a benign proliferation of the stratified squamous epithelium, which results in a papillary or verrucous exophytic mass. OSCP is usually associated with human papilloma virus. Although any surface of the oral cavity can be affected, the sites of predilection for localization of the lesions include the tongue, lip and soft palate. In this report, treatment and histological findings of a local gingival enlargement at the vestibular side of the upper right central tooth of a 10 year-old systemically healthy girl are presented. The lesion was asymptomatic and had shown a slow growth. Solitary, exophytic lesion was clinically soft, pink-white in color and appeared as cauliflower. Dental and periodontal tissues were radiographically normal. One month after scaling and root planing, under local anesthesia the lesion was excised and this was followed by the use of Nd: YAG laser (1064 nm, 20 Hz, 3 W) to control bleeding, minimize pain and scarring in post-operative period, and provide sterilization. Macroscopic examination revealed that the lesion was 1.1x0.5x0.2 cm(3) in size, yellow in colour and had a rough surface, while histological examination showed multi-layer connective tissue underlying the squamous epithelium, numerous rete pegs and spinous cell proliferation at the papillary and OSCP was diagnosed. There was no evidence of viral cytopathic effect or malignancy of the lesion. No recurrence was observed during the 4-year follow-up period..Publication Open Access Klorheksidinin insan dişeti fibroblastları üzerindeki hücre canlılığı ve sitotoksisite etkinliğinin in vitro koşullarda değerlendirilmesi(2023-04-01) YILMAZ GÖLER, AYŞE MİNE; ÖZTÜRK ÖZENER, HAFİZE; Bayraktar G., YILMAZ GÖLER A. M., ÖZTÜRK H.Amaç: Bu in vitro çalışmada, % 0,2’lik klorheksidin (CHX) solüsyonunun, insan dişeti fibroblast (HGF) hücre canlılığı ve sitotoksisitesi üzerindeki etkilerinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntemler: Bu çalışma 30 saniye ve 2 dakikalık zaman aralıklarında, nötr pH değerindeki % 0,2’lik CHX solüsyonu ve hücre olarak ATCC’den ticari olarak temin edilen HGF-1 (CRL2014) hücre hatları kullanılarak gerçekleştirildi. CHX’in HGF üzerindeki hücre canlılığı etkileri 3-(4,5-dimetiltiazol-2-il)-2,5- difeniltetrazolyum bromür (MTT) testi ile ve sitotoksik etkileri laktat dehidrogenaz (LDH) testi ile değerlendirildi. Sonuçlar ortalama ve standart sapma değerleri kullanılarak two way ANOVA testiyle istatistiksel olarak analiz edildi (p<0,05). Bulgular: MTT testi sonuçlarına göre, % 0,2 CHX solüsyonunun zamanla hücre canlılığını azalttığı görüldü (p<0,0001). LDH testi sonuçlarına göre ise % 0,2 CHX’in sitotoksik etkinliğinin kontrol grubuna kıyasla arttığı (p<0,0001) ancak zaman içinde istatistiksel olarak anlamlı bir fark göstermediği (p>0,05) gözlendi. Sonuç: Bu in vitro çalışmanın sınırları dahilinde, % 0,2 CHX solüsyonu, 30 sn ve 2 dk’lık kısa maruz kalma sürelerinde, HGF hücre canlılığını azalttı ve HGF üzerinde sitotoksik etki gösterdi.Publication Metadata only Yaşlı Bireylerde Cerrahi Olmayan Periodontal Tedavi Yaklaşımı(Türkiye Klinikleri Yayınevi, 2022-12-01) ÖZTÜRK ÖZENER, HAFİZE; AĞRALI, ÖMER BİRKAN; DOĞAN, BAŞAK; Öztürk Özener H., Ağralı Ö. B., Doğan B.Publication Open Access Periodontal treatment approach for dihydropyridine induced gingival overgrowth with or without drug substitution(2022-06-01) ÖZTÜRK ÖZENER, HAFİZE; KURU, LEYLA; Eroğlu O., YETİŞ E., ÖZTÜRK H., KURU L.Objectives: The aim of this study is to evaluate clinical effectiveness of nonsurgical periodontal treatment (NSPT) in patients with drug induced gingival overgrowth (DIGO) with or without drug substitution in comparison with patients presenting inflammatory gingival overgrowth (GO). Material and Methods: A total of 17 patients with generalized GO were included in this clinical trial. Based on the medical physicians consultation, DIGO patients who continued using dihydropyridine were allocated to the Group 1 (n=6), whereas patients whose drug substitution was carried out were allocated to the Group 2 (n=5). Group 3 (n=6) subjects had inflammatory GO. All study groups received NSPT for 4 sessions. At baseline and 6 weeks after NSPT, plaque index, gingival index, bleeding on probing (BOP), probing depth (PD) and, plaster model and photographic GO scores were measured. Results: NSPT resulted in significant decreases in periodontal clinical parameters in all groups (p<0.05). Intergroup comparisons of baseline measurements revealed no statistically significant differences (p>0.05) except PD value which was higher in the Group 1 compared to the Group 2 (p<0.05). Comparisons of post-NSPT data among groups exhibited statistically significant difference only between Groups 1 and 2 in the model and photographic GO scores (p<0.05). Conclusions: After the 6-week evaluation period, NSPT was found to be an effective method in reducing the severity of inflammation and size of overgrown gingival tissues in patients with DIGO and inflamatory GO. Substitution of drug causing GO provided further contribution to NSPT regarding the size of overgrown gingiva in the patients with DIGO.Publication Metadata only Yaşlı bireylerde cerrahi olmayan periodontal tedavi yaklaşımı(Türkiye Klinikleri, 2022-01-01) ÖZTÜRK ÖZENER, HAFİZE; AĞRALI, ÖMER BİRKAN; DOĞAN, BAŞAK; ÖZTÜRK H., AĞRALI Ö. B., DOĞAN B.Publication Open Access Different treatment approaches for the localized gingival overgrowths: Case series(2018-04) DOĞAN, BAŞAK; Ozener, Hafize Ozturk; Kundak, Kubra; Sipahi, Nimet Gul; Yetis, Ece; Dogan, BasakABSTRACT Localized gingival overgrowths belong to a common group of lesions designated as focal reactive overgrowths. They occur in response to chronic, low‑grade irritation caused by plaque or any other irritant. They have multifactorial etiopathology but exhibit similar clinical features with slight variations in patient complaints. Success of the lesions’ management depends on formation of healthy contours of the surgical area after excision of lesion and absence of a recurrence. The purpose of case series is to present 6 different cases of localized gingival overgrowths and their management with the following techniques: nonsurgical periodontal treatment, gingivectomy, flap surgery, free gingival graft, gingival unit, and connective tissue graft.Publication Open Access Evaluation of the Effectiveness of Esterified Hyaluronic Acid Fibers on Bone Regeneration in Rat Calvarial Defects(HINDAWI LTD, 2018-06-28) ÖZBEYLİ, DİLEK; Agrali, Omer B.; Yildirim, Selin; Ozener, Hafize O.; Kose, Kemal N.; Ozbeyli, Dilek; Soluk-Tekkesin, Merva; Kuru, LeylaHyaluronic acid (HA) constitutes one of the major components of the extracellular matrix domain in almost all mammals. The aim of this study was to evaluate the regenerative capacity of HA matrix in rat calvarial bone defects and compare with those of different combinations of resorbable collagen membrane (M) and bovine-derived xenograft (G). Twenty-four 3-month-old male Sprague-Dawley rats weighing 200-250 g were included. Control group was created by leaving one defect empty from 2 critical size defects with 5 mm diameter formed in the calvarial bones of 8 rats. In the same rats, the other defect was treated with HA matrix alone. One of the 2 defects formed in other 8 rats was treated with HA + G and the other with HA + M. One of the 2 defects formed in the remaining 8 rats was treated wilh G+M and the other with HA+G+M. The animals were sacrificed at 4 weeks. Histologic, histomorphometric, and immunohistochemical analyses were performed. Both HA matrix alone and its combinalions with G and M supported new bone formation (NBF). However, NBF was significantly greater in G+M and HA+G+M groups compared to control and HA alone (P < 0.00l). Bone morphogenetic protein-2 was expressed with varying degrees in all groups, without any difference among them. Within the limitations of the present study, HA matrix, used alone or in combination with G and M, did not contribute significantly to bone regeneration in rat calvarial bone defects.Publication Open Access Assessment of reliability of three indices measuring gingival overgrowth procjena pouzdanosti triju indeksa za mjerenje hiperplazije gingive(2023-06-01) ÖZTÜRK ÖZENER, HAFİZE; KURU, LEYLA; Alkateb A. S., ÖZTÜRK ÖZENER H., KURU L.Objectives: Numerous indices have been used to grade the severity of gingival overgrowth which led to suspicion regarding the results concerning its prevalence and pathogenicity. The aim of this study was to assess the concordance of three different gingival overgrowth indices, which were used wide-ly in previous studies, and check their reliability and reproducibility. Material and Methods: A total of 30 full-mouth plaster casts and 90 intra-oral photographs collected from 30 patients diagnosed with gingival overgrowth were included in our study. Three trained examiners performed measurements twice on plaster casts using gingival hyperplasia index (A index) and hyperplastic index (B index). In-traoral photographs were assessed also twice using (C index). Results: Concordance of intra-exam-iner and inter-examiner reliability of the recorded measurements was carried out for each index using weighted kappa (K), with a confidence interval of 95%. The A index revealed intra-examiner total kappa values between 0.724-0.876 for horizontal measurement and 0.512-0.823 for vertical mea-surement, and inter-examiner total kappa values between 0.255-0.626 horizontally and 0.235-0.279 vertically. The B index presented intra-examiner total kappa values between 0.587-0.868 horizontally and 0.653-0.855 vertically; and inter-examiner total kappa values between 0.393-0.595 and 0.372-0.635 for horizontal and vertical measurements, respectively. The C index achieved the highest intra-examiner concordance with total kappa values between 0.758-0.855 and inter-examiner total kappa values between 0.716-0.804. Conclusions: The C index evaluated through intraoral photographs is considered the most reliable and applicable method to be utilized. The C index is suggested to be used in large scale populations with its definite detailed criteria.Publication Metadata only Radiographic Evaluation of the Effect of Vitamin D3 Supplementation on Regeneration of Calvarial Bone Defects in Rats(2023-09-01) AĞRALI, ÖMER BİRKAN; YILDIRIM, HATİCE SELİN; KURU, LEYLA; ÖZTÜRK ÖZENER, HAFİZE; HANCILAR G.
