    What changed in the blood concentrates? Innovations and Current Clinical Applications
    (2019-09-30) Tunalı, Mustafa; TUNALI, MUSTAFA
    Kan Konsantrelerinde Ne Değişti? Yenilikler ve Güncel Klinik Uygulamalar Doç. Dr. Mustafa Tunalı Vücudumuzun orjinal tamir materyalini, kendi kanımızı, tamir ve rejenerasyonda kullanma felsefesine dayanan otojen kan konsantrelerinin geçmişi yarım asır’a yaklaşmaktadır. Bu ürünlerin tarihi, fibrin doku yapıştırıcıları ile başlayarak, günümüzde çok çeşitli Platelet Rich Plazmalar ve Platelet Rich Fibrinler ile devam etmektedir. Kan konsantrelerinin en güncel, gelişmiş ürünleri ise Platelet Rich Fibrinlerin injekte edilebilen tipleri ve klinik kullanım için modifiye edilmiş hibrit ürünlerdir. Otojen kan konsantrelerinin gelecekte de Tıp ve Diş Hekimliğinde önemli bir yere sahip olacaklarını düşünebiliriz. Bu yeni çalışmalar, doku mühendisliğindeki yeniliklerle de birleştiğinde farklı bir okuryazarlık ortaya çıkmaktadır. Biyolojik dil okuryazarlığı. Biyolojik dilde biyoloji ile diyalog önemli bir nokta olarak göze çarpmaktadır, sadece biyolojiyi anlamak değil, biyolojiye de kendimizi anlatmamız ve vücudumuzun da bizim ne yapmaya çalıştığımızı anlaması önemli bir aşama olabilir. Doç. Dr. Mustafa Tunalı, Bezmialem Vakıf Üniversitesi Diş Hekimliği Fakültesi, Periodontoloji Anabilim Dalında öğretim üyesi olarak görev yapmaktadır.

Prof. Dr. Mustafa Tunalı The history of autogenous blood concentrates, which is based on the philosophy of using our body-s original repair material, our own blood, in repair and regeneration, is approaching half a century. The history of these products, starting with fibrin tissue adhesives, continues today with a wide variety of Platelet Rich Plasmas and Platelet Rich Fibrins. The most current and advanced products of blood concentrates are the injectable types of Platelet Rich Fibrins and hybrid products modified for clinical use. Autogenous blood concentrates may still have an important place in medicine and dentistry in the future. When these new studies are combined with innovations in tissue engineering, a different literacy emerges. Biological language literacy. Dialogue with biology stands out as an important point in biological language, not only understanding biology, but also explaining ourselves to biology and our body. It may be an important step when our bodies understand what we are trying to do. Dr. Mustafa Tunalı, DDS, PhD, now is an Associate Professor of Periodontology, Bezmialem Vakif University School of Dentistry, Department of Periodontology.

An external root resorption at the tooth number 44 was detected on the 6th month follow-up of the operation.In this case, endodontic treatment of external root resorption was performed by removing the flap. The success of rootclosure and maintenance of the width and thickness of the keratinized tissue was aimed.Case Report: On the 6th month follow-up, the patient had pain on palpation and percussion and the tooth was devital. Accordingto clinical and radiographic examination of the relevant tooth had not carious and had periapical lesion associated with apicalin the root. During root canal treatment, cervical root resorption was seen in the buccal root cavity of the endodontic clinic.Since the resorption site was located below the gingival margin, it was predicted that restoration of the defect should be performedsimultaneously with the root canal filling. After the canal preparation was completed, themedicament of the canal wasinserted and temporary restoration was applied. Preoperative 40 cc venous blood from the patient was prepared by centrifugationat 2800 rpm-12minutes. The flap was removed to allow adequate visibility and operation. After root canal filling and restorationwith reinforced glass ionomer (GC equia), the region was closed primarily by Zuchelli suture by placing the T-PRF.Conclusion: After the simultaneous endodontic and periodontal treatment of the external root resorption site of the tooth toperformed the root closure operation, it was seen that the gingival thickness and the attachment gain increased according tothe results of 3 months. More and longer- term work is needed in this regard.Keywords: T-PRF, PRF, External Root Resorption, Glass IonomerTürk Dişhekimleri Birliği 25.

    The impact of Er:YAG laser enamel conditioning on the microleakage of a new hydrophilic sealant-UltraSeal XT (R) hydro (TM)
    (2016-05-01) GÜÇLÜ, ZEYNEP ASLI; DÖNMEZ, NAZMİYE; TÜZÜNER, TAMER; ODABAŞ, MESUT ENES; HURT, Andrew p; COLEMAN, Nicola; DÖNMEZ, NAZMİYE
    UltraSeal XT hydro is a new hydrophilic, light-cured, methacrylate-based pit and fissure sealant which has been developed by Ultradent Products, USA. The sealant is highly filled with a 53 wt.% mixture of inorganic particles which confer both thixotropy and radiopacity. The principal purpose of this study was to investigate the microleakage of UltraSeal XT hydro as a function of different enamel etching techniques. The occlusal surfaces of sound, extracted human molars were either acid etched, Er:YAG laser irradiated or successively laser irradiated and acid etched. UltraSeal XT hydro was applied to each group of teeth (n = 10) which were subjected to a thermocycling process consisting of 2500 cycles between 5 and 50 °C with a dwell time of 30 s. Microleakage assessments were then carried out using 0.5% fuchsin dye and optical microscopy. The microleakage score data were analysed using the Kruskal-Wallis, Mann-Whitney U test with Bonferroni adjustment. No significant differences in microleakage were noted between the individually acid etched and laser-irradiated groups (p > 0.05); however, teeth treated with a combination of laser irradiation and acid etching demonstrated significantly lower microleakage scores (p < 0.001). Electron microscopy with energy-dispersive X-ray analysis revealed that the mineral filler component of UltraSeal XT hydro essentially comprises micrometre-sized particles of inorganic silicon-, aluminium- and barium-bearing phases. Laser etching increases the roughness of the enamel surface which causes a concentrated zoning of the filler particles at the enamel-sealant interface.

    The effect of surface treatments on the bonding strength of ceramic inlays to dentin
    (2017-01-01) Kara, Ozlem; Ozturk, Atiye Nilgun; KARA, ÖZLEM
    Aim: To compare and evaluate the effects of different surface treatments on surface roughness and the microtensile bonding strengths of four different ceramics to dentin. Methods: 160 human molar teeth were used. The teeth were divided into four groups (n=40). FC (Finesse), LC (IPS Empress Esthetics), LDC (IPS Empress e-Max) and MZC (Zirkonzahn Prettau) ceramic restorations were prepared. The specimens were divided into eight groups: (1) control, (2) air abrasion (AA), (3) HF acid etching (HF), (4) experimental hot etching (EHE), (5) Nd:YAG laser irradiation, (6) Nd:YAG laser+air abrasion, (7) Nd:YAG laser+HF acid, and (8) Nd:YAG laser+experimental hot etching. The surface roughness of the ceramics was determined with atomic force microscopy. After the cementation process, the specimens were thermal cycled and subjected to a microtensile bond strength (MBS) test. Two-way ANOVA and a Tukey-s test were used to analyse the surface roughness and MBS values of variance (p=0.05). Results: HF acid etching showed the highest surface roughness in FC (p<0.05). HF increased MBS in LC specimens where AA and HF increased MBS in LCD specimens. For the MZC specimens, AA and Nd:YAG+AA was effective in increasing the MBS (p<0.05). Conclusion: Different surface treatments must be applied to different ceramics to improve the mechanical retention and MBS.

    Mechanical properties of zirconia after different surface treatments and repeated firings
    (2014-12-01) Subasi, Meryem Gulce; Demir, Necla; Kara, Ozlem; Ozturk, A. Nilgun; Ozel, Faruk; KARA, ÖZLEM
    This study investigated the influence of surface conditioning procedures and repeated firings on monoclinic content and strength of zirconia before cementation. MATERIALS AND METHODS. Sintered barshaped zirconia specimens were subjected to no surface treatment (control), air abrasion, or grinding (n=21). Their roughness was evaluated using a profilometer, and microscope analysis was performed on one specimen of each group. Then, 2 or 10 repeated firings (n=10) were executed, the monoclinic content of specimens was analyzed by X-ray diffraction, and a three-point flexural strength test was performed. Surface roughness values were compared using one-way analysis of variance (ANOVA) and Tukey honestly significant difference (HSD) tests, the monoclinic content values were tested using Kruskal-Wallis and Mann-Whitney U tests, and the flexural strength values were tested using two-way ANOVA and Tukey HSD tests (P=.05). Spearman’s correlation test was performed to define relationships among measured parameters. RESULTS. Surface-treated specimens were rougher than untreated specimens and had a higher monoclinic content (P<.005), and the relationship between roughness and monoclinic content was significant (P<.000). Neither surface treatment nor firing significantly affected the flexural strength, but Weibull analysis showed that for the air-abraded samples the characteristic strength was significantly lower after the 10th firing than after the 2nd firing. CONCLUSION. After firing, a negligible amount of monoclinic content remained on the zirconia surfaces, and rougher surfaces had higher monoclinic contents than untreated surfaces. Multiple firings could be performed if necessary, but the fracture probability could increase after multiple firings for rougher surfaces

    Effect of cleansers on denture base resins- structural properties
    (2019-02-01) Ozyilmaz, Ozgun Yusuf; Akin, Ceyda; ÖZYILMAZ, ÖZGÜN YUSUF
    Introduction: We assessed the effect of different available denture cleansers on the roughness and hardness of polyetherketoneketone, thermoinjection-molded polyamide, and polymethylmethacrylate. Materials and Methods: A total of 150 disc-shaped specimens were fabricated (10 mm × 2 mm) from these three denture base resins, and divided into five subgroups (n = 10) according to immersion procedures. One of these groups subjected to distilled water served as control, whereas other groups were subjected to daily cleansing with four denture cleansers (Corega, Protefix, Curaprox, and Perlodent) for 8 h a day for 140 days. The surface roughness and hardness values of specimens were recorded by measuring twice at baseline, and again after application of chemical solutions. Topography alterations after treatments were assessed with scanning electron microscopy. The data were subjected to statistical analysis and comparison among groups was done using Kruskal Wallis and Wilcoxon Signed Ranks tests. P-value <0.05 was considered significant. Results: The surface roughness of polyetherketoneketone, polymethylmethacrylate, and polyamide dentures was increased significantly by chemical solutions of denture cleansers. While the hardness value of polyetherketoneketone was not affected significantly after immersion in denture cleansers, those of polymethylmethacrylate and polyamide decreased significantly. Compared with Curaprox, the effervescent tablets significantly altered the surface hardness and roughness of polyamide. Conclusion: Denture cleansers can considerably alter the surface roughness and hardness of denture base resins and should be used carefully depending on the material.

    Schwannoma is a tumor which has neuroectoderm origins, is hard, well-circumscribed, encapsulated, and slow growing benign cranial tumor, and may autonomously grow out of the nerve sheath of peripheral nerves. It is mostly seen in the head and neck region. In the paranasal sinus and nose areas, it is seen at a rate of 4%. The diagnosis is mostly made after histopathological examination. In this paper, a Schwannoma case observed in the nasopharyngeal region was presented in a 20-year-old female who had complaints of sleeping with open mouth, snoring, foreign body feeling in throat, and swallowing difficulties. The tumor was extracted via transoral approach. No recurrence was observed during follow-up over the next year. This case presentation is presented for the first time in the literature in English.

Shallow vestibuledepth, long buccal muscle fibers, strong lip muscles, stubborn frenulum attachments significantly affect the prognosis of gingivalrecessions.The long-term success of many treatment of gingival recession depends on the correct removal and non-recurrenceof muscle fibers that may re-occur and create stress in the tissue.with the web coronale flap technique, these muscle fibers and frenulum attachments can be removed in a controlled mannerin case of multiple gingival recessions. It also allows for maximum tissue stabilization in early wound healing while maintainingadequate blood flow for tissue living. Shallow depth of vestibule and long frenulum muscle connections are eliminated andcontribute to clot organization. T-PRF applied to both the root surface and the deepened apical region creates a natural factoreffect that increases keratinization and soft tissue thickness (histoconduction).In this case series, web coronale flap surgical treatment and 12-month follow-up of 16 Miller class I multiple gingival recessiondefects are presented. Initial average gingival recession depth was 2,75mmand average keratinized gingival width was 3.68mm.The aesthetic and sensitivity problems of the patients were eliminated by web coronale flap and T-PRF surgical treatment of exposedroot surfaces. At the end of 12 months follow-up, 71.33% mean root coverage and 4.06 mm keratinized gingival widthwere obtained in the treatment of multiple gingival recession defects.T-PRF is an easy-to-obtain, fully autogenous, tight natural matrix biomaterial that can be successfully applied in the treatmentof multiple gingival recessions with a new technique, web coronale-positioned flap.Keywords: Gingival recession, T-PRF, root coverage, periodontal surgery, estheticTürk Dişhekimleri Birliği 25.

    Objective In the present study, the ability of posterior resin composite to repair aged bulk-fill resin composite and vice versa were assessed by shear bond strength testing. Materials and Methods Resin composite substrates were aged and surfaces were abraded with abrasive papers, then bulk-fill substrates were repaired with posterior resin composite and vice versa using different surface treatments (no surface treatment [control]; etching with 37% phosphoric acid [H3PO4] for 20 seconds; etching with 10% hydrofluoric acid [HF] for 20 seconds; etching with 37% H3PO4 for 20 seconds + adhesive application; etching with 10% HF for 20 seconds + adhesive application; adhesive application only). Shear bond strengths (SBS) were then measured and surface roughness values (Ra) were determined. Cohesive strengths of nonaged resin composites were measured and used as reference groups. Resin composite surfaces after acid etching were evaluated by SEM. Data were analyzed using ANOVA and Fisher-s LSD tests (P < .05). Results ANOVA showed that resin composite repair type did not affect SBS significantly (P = .850), while it showed that surface treatments significantly affected the SBS (P = .000). Only a combination of etching with 10% HF for 20 seconds with resin adhesive application provided similar SBS values with those of the positive control. Conclusions It was concluded that the aged bulk-fill resin composite would be effectively repaired with conventional posterior resin composite or vice versa if proper repair protocol was deployed. Clinical Significance The combination of 10% HF etching and adhesive application would provide efficient repair strength when the aged bulk fill resin composite is repaired with conventional posterior resin composite or vice versa.
