    2014 IEEE Global Communications Conference, GLOBECOM 2014 -- 8 December 2014 through 12 December 2014 -- 110905The comprehensive treatment of a patient with cleft lip and palate requires an interdisciplinary approach for functional and esthetic outcomes. A 20-year-old woman with bilateral cleft lip and palate had a chief complaint of unesthetic appearance of her teeth and the presence of oronasal fistulae. Her clinical and radiographic evaluation showed a dolichofacial growth pattern, a Class II skeletal relationship with retroclined maxillary central incisors, 5 mm of negative overjet, maxillary constriction, maxillary and mandibular crowding, congenitally missing maxillary right incisors and left lateral incisor, and a transposed maxillary left canine. Her treatment plan included the extraction of 3 premolars, maxillary expansion, segmental maxillary osteotomy, repair of the oronasal fistulae, rhinoplasty, periodontal surgery, and prosthodontic rehabilitation. To obtain a better occlusion and reduce the dimensions of the fistulae, orthognathic surgery comprising linear and rotational movements of the maxillary segments (premaxilla, right and left maxillary alveolar segments) in all 3 axes was planned by performing 3-dimensional virtual surgery on 3-dimensional computerized tomography. At the end of the interdisciplinary treatment, a functional occlusion, a harmonious profile, and patient satisfaction were achieved. Posttreatment records after 1 year showed stable results

    Aim: The aim of this study was to evaluate the effects of prophylactic polishing protocols and mouth rinses on surface roughness of different tooth colored restoratives that were generally preferred for Class V cavities.Materials and Methods: A reinforced conventional glass ionomer, a resin modified glass ionomer, a flowable, and a nanohybrid composite were used. Forty specimens for each restorative materials were fabricated and polished and baseline surface roughness (Ra) measurements were obtained by a profilometer. Then the specimens were divided into two groups according to prophylactic polishing pro-tocols: ultrasonic scaling or ultrasonic scaling and air polishing. Following Ra measurements prophy-lactic polishing protocols groups were divided into two subgroups for two different mouth rinses im-mersion and Ra measurements were obtained afterwards. Finally the specimens were re-polished and Ra values were recorded. Results: Prophylactic polishing protocols, especially air polishing, resulted in significant increases in surface roughness (p<0.001) while mouth rinses had minimal effects (p>0.05). Re-polishing proce-dures decreased surface roughness values. Tested glass ionomers showed worse surface roughness values compared with resin composites. Conclusion: Result of this research indicated that prophylactic polishing protocols increased surface roughness values of restorative materials, especially glass ionomers.Amaç: Bu çalışmanın amacı profilaktik polisaj protokolleri ve ağız gargaralarının genellikle sınıf V kaviteler için tercih edilen farklı adeziv restoratif materyallerin yüzey pürüzlülüğü üzerine etkisini incelemektir. Gereç ve Yöntem: Güçlendirilmiş geleneksel cam iyonomer, rezin modifiye cam iyonomer, akışkan composit ve nanohibrid kompozit kullanılmıştır. Her restoratif materyalden 40 örnek hazırlanmış, polisaj yapılmış ve profilometre ile başlangıç yüzey pürüzlülüğü ölçümleri elde edilmiştir. Örnekler daha sonra profilaktik polisaj protokollerine göre iki gruba ayrılmıştır: ultrasonic temizleme; ultrasonic temizleme ve air polishing. Ra değerlerinin elde edilmesinin ardından gruplar iki alt gru-ba ayrılmış ve farklı iki ağız gargasına maruz kalmış ve Ra değerleri elde edilmiştir. Son olarak örnekler tekrar polisajlanıp son Ra ölçümleri alınmıştır. Bulgular: Profilaktik polisaj protokolları, özellikle air polishing, yüzey pürüzlülüğünde anlamlı derecede artışa sebep olurken (p0.05). Tekrar polisajlama uygulaması yüzey pürüzlülüğünü değerlerini düşürmüştür. Kompozitlerle karşılaştırıldığında test edilen cam iyonomerler daha kötü yüzey pürüzlülüğü değerleri vermiştir. Sonuç: Bu çalışmanın sonucu profilaktik polisaj protokollerinin restoratif materyallerin özellikle cam iyonomerlerin yüzey pürüzlülüğünü artırdığını göstermiştir

    Background and Aim: The purpose of this study was to understand and monitor the transition from primary to secondary stability of implants having sand blast large grit acid etched surface, for the timing of the prosthodontic treatment via using the Radio Frequency Analysis. Subjects and Methods: Forty-two dental implants were placed in 19 patients and Implant Stability Quotient measurements were performed at baseline, 1st, 2nd, 3rd, 4th, 6th and 8th weeks. The lengths and diameters of the implants were also correlated with Implant Stability Quotient values. Results: The present data showed no correlation between lengths, diameters and Radio Frequency Analysis at any of the measurement times. In each group, implant stability at the baseline and 8th weeks showed significant higher Radio Frequency Analysis (RFA) values than the 2nd, 3rd and 4th weeks (p<0.05). Statistically no difference was found between the baseline and 8th week measurements (p>0.05).Conclusion: Measuring Implant Stability Quotient values can help the clinician understand the condition of the implant without disrupting the healing implant-bone interface, allowing to decide the loading time.Amaç: Bu çalışmanın amacı, kumlanmış-asitlenmiş yüzeye sahip implantların primer stabiliteden sekonder stabiliteye geçişini, Radyo Frekans Analiz yöntemi kullanarak anlamak ve gözlemlemektir. Bireyler ve Yöntem: Ondokuz hastada 42 implant yerleştirilmiş ve başlangıç, 1, 2, 3, 4, 6 ve 8. haftalarda İmplant Stabilite ölçümleri (Implant Stability Quotient-ISQ) yapılmıştır. Bulgular: Elde edilen bilgiler, implantların boyu ve çapı ile Radyo Frekans Analiz ölçümleri arasında hiçbir zaman diliminde ilişki göstermemektedir. Tüm gruplarda implant stabilitesi, başlangıç ve 8. haftada 2, 3 ve 4. haftalara göre anlamlı derecede yüksek İmplant Stabilite ölçüm değeri göstermiştir (p0.05).Sonuçlar: İmplant Stabilite değerlerini ölçmek, iyileşen implantkemik bağlantısına zarar vermeden, implantın iyileşme durumu hakkında fikir vererek yükleme zamanının kararında hekime yardımcı olabilir

    AMAÇ: Bu çalışmanın amacı sistemik sağlık üzerinde et-kisi kanıtlanmış olan periodontal durumun infertil kadın-larda uygulanan in vitro fertilizasyon tedavisi sonuçları üzerindeki etkisini değerlendirmektir. GEREÇ VE YÖNTEM: İnfertilite tanısı konmuş kadın has-talardan sosyodemografik veriler bir anket yardımıyla toplanmıştır. Kan testi gününde plak indeksi, gingival indeks, cep derinliği, sondalamada kanama indeksi öl-çümleri yapılmıştır. Buna göre; sağlıklı, gingivitisli ve pe-riodontitisli olarak sınıflandırılan hastalar ile kullanılan human chorionic hormon gonadotropin (hCG) dozu, öst-radiol ve progesteron seviyeleri, transfer edilen embriyo sayıları, oosit sayıları ve gebelik sonuçları karşılaştırılmış-tır. Çalışmada, tek yönlü ANOVA, Tukey HDS, Tampane’s T2, Kruskal-Wallis, Mann-Whitney U ve ki-kare testleri kullanılmıştır. BULGULAR: Gruplar arasında oosit sayıları, transfer edi-len embriyo sayıları ve gebelik sonuçları açısından bir farklılık gözlenmemiştir. Gruplar arasında hCG günü öst-radiol seviyesi açısından bir farklılık gözlenmemesine karşın hCG günü progesteron seviyesi periodontitis gru-bunda sağlıklı ve gingivitisli gruba göre anlamlı şekilde yüksek bulunmuştur. SONUÇ:Periodontitis grubunda gözlenen progesteron seviyesindeki yükselme IVF sonucunu etkileyebilecek olan eşik değerin altındadır. Periodontal durumun inferti-lite tedavisi üzerindeki etki mekanizmasının belirlenmesi için geniş ölçekli ve uzun vadeli çalışmalara ihtiyaç duyul-maktadır.OBJECTIVE: This study aims to evaluate the effect of pe-riodontal status, which has been proven to have effects on systemic health, on the outcomes of in vitro fertiliza-tion (IVF) treatment which is applied to infertile women. MATERIAL AND METHODS: Sociodemographic data have been collected from female patients diagnosed with infertility through a questionnaire. On the day of the blood test, plaque index, gingival index, probing depth and bleeding index on probing were measured. Recruited patients were classified into the healthy, gin-givitis, and periodontitis groups according to the afore-mentioned criteria. These groups were compared with respect to human chorionic gonadotropin (hCG) dosage, estradiol and progesterone levels, the number of oocy-te and embryos transferred, and pregnancy outcomes. One-way ANOVA, Tukey HDS, Tampane’s T2, Kruskal-Wal-lis, Mann-Whitney U, and chi-square tests were used in this study. RESULTS: The three groups were statistically similar in the aspect of retrieved oocytes, transferred embryos and pregnancy outcomes. Although three groups had statistically similar in terms of estradiol levels on the day of hCG administration, progesterone levels were signifi-cantly higher in the periodontitis group compared to he-althy and gingivitis groups.CONCLUSIONS: This elevation in progesterone levels ob-served in the periodontitis group is below the threshold level which could affect the IVF outcomes. Large scale and long-term studies are needed to clarify the effects of periodontal status on IVF outcomes

    The excess cement not removed after the cementation of fixed implant-supported restorations may cause loss of peri-implant attachment or adjacent bone. The aims of this study were to evaluate the amount of residual cement at different abutment-crown connection levels and to test the cleaning efficacy of poly-ether-ether-ketone (PEEK) ultrasonic tips after cementation. One implant was placed in an anterior central tooth position 5 mm below the gingival margin in an acrylic model, and 32 stone models were obtained with implant analogs. Abutment heights of 1-2 and 2.5-4 mm were used on the vestibular and lingual sides, respectively. Crowns were cemented and cleaned, and half of the samples were cleaned again using PEEK tips. The abutment-crown suprastructure was then disconnected, and cleaning efficacy was evaluated. Varying amounts of excess cement were found on all specimens except for the PEEK group with abutment-crown connections 1 mm below the gingival margin. An increase of undetected cement remnants was observed when the restoration margins were located deeper subgingivally. Various amounts of excess cement associated with margin location were detected on the abutment-restoration complex despite meticulous cleaning efforts. Ultrasonic PEEK tips were effective at cleaning the cement remnants around implants to a certain depth
