Objectives: The present study aimed to compare microhardness of inactive proximal lesions treated by resin infiltration, Er:YAG laser + resin infiltration and Bioactive glass, and investigate the resistance of treated lesions to further demineralization challenge. Methods: In this in-vitro study, 30 human molars with inactive proximal lesions were selected and randomly divided into three groups of 10. In group 1 (resin infiltration), the lesions were treated by a resin infiltrant (Icon). In group 2, the surface was conditioned by an Er:YAG laser prior to resin infiltration. The specimens in group 3 were remineralized by bioactive glass. The treated specimens were kept in artificial saliva for 1 week and then immersed in a demineralization solution for 8 weeks. Surface microhardness was measured at baseline (T0), after remineralization (T1) and after exposure to the demineralization solution (T2), and the difference in microhardness between time points (ΔVHN) was calculated. Results: Microhardness after demineralization (T2) was significantly lower than those of other intervals (P0.05). The statistical analysis revealed no significant difference either in ΔVHNT1-T0 or in ΔVHNT2-T1 among the study groups (P>0.05) Conclusion: Pretreatment by the Er:YAG laser prior to resin infiltration was more effective that other treatments in enhancing microhardness and protecting the tooth against acidic challenge. However, the difference between groups did not reach a statistical significance, implying the need for further studies to achieve more conclusive results.

Aim: The aim of this study was to compare the shear bond strength (SBS) and adhesive remnant index of stainless-steel brackets bonded with different orthodontic adhesive systems. Materials and Methods: In our study performed on 60 premolar teeth extracted for orthodontic reasons, MBT prescription 0.022'' stainless-steel brackets (Discovery Smart®, Dentaurum, Germany) were used. In teeth randomly divided into 3 groups, bonding was performed with Group 1: Trulock Light Activated Bonding System (RMO, USA), Group 2: Bisco Ortho Bracket Paste LC (Bisco, USA), Group 3: Transbond XT Light Cure Adhesive (3M, USA). SBS and residual adhesive indexes (ARI) were evaluated by breaking the samples. Adhesive residues were cleaned with tungsten carbide burs from the surfaces of the teeth, rebonding was made after sanding the brackets’ surfaces. SBS and ARI values were re-evaluated. One-way ANOVA, two-sample t-test and Mann-Whitney U tests were used for statistical analysis of the data, p <0.05 was considered statistically significant. Results: Statistically significant differences were observed between Group 1 and Group 2 in comparison to the first SBS values of three different orthodontic adhesive systems to enamel (p <0.05). Among the adhesive systems, only a statistically significant difference was found between the first bonding values and the rebonding values of Group 2 (p <0.05). There was no statistically significant difference between the first and rebond strengths of the other two adhesive systems. Rebonding values of three different orthodontic adhesive systems were very close to each other. Conclusions: The results of this study suggest that the adhesive systems developed for the bonding of orthodontic brackets to the enamel can show clinically enough bond strength even if the rebonding strengths of the falling stainless-steel brackets to the same enamel surfaces decrease slightly.

Abstract: This clinical case report describes a prosthetic rehabilitation for a patient who had partial maxillectomy surgery following the diagnosis of maxillary squamous cell carcinoma in 1991. She was also previously diagnosed with parotid gland pathology on the right and required complete removal of gland along with facial nerve. Her previous prosthesis is 18 years old and claims it not as retentive as before. Intraorally there was a large oval shaped defect on the right side of the maxilla sparing the left alveolus. Defect extends more than 2/3rd of the palatal area with communication to the nasal floor. Presence of buccal frenal pull on the right side on the upper and lower jaws due to the wound contracture on that side of the face. The extraoral facial asymmetry and weakness of facial muscles in this patient may lead to improper denture border seal of the prosthesis. Patient was provided with maxillary acrylic obturator and mandibular acrylic complete denture as a definitive treatment with careful denture extension planning. She was reviewed multiple times till prosthesis stability intraorally was achieved. This improved the prognosis for this patient. The only option for retaining prosthesis in this case, without implants, is optimum engagement of the available soft-tissue undercuts found within the defect space and the non-affected side. Keywords: Completely Edentulous, Obturator, Facial Nerve, Prognosis, Case Report.

Abstract Objective: This study aimed to investigate the prevalence and dimensions of pineal gland calcification using cone-beam computed tomography (CBCT) in patients undergoing dental treatment. Materials and Methods: CBCTs that localized pineal gland in the fov range was selected in this retrospective study. The presence of pineal gland calcification (PGC) was noted. Vertical, horizontal and areal measurements were made by a single observer (M.S). Variables such as age, gender for each patient were recorded using previous clinical examination data. Results: The prevalence of pineal gland calcification was 33.64% (female to male ratio 3:2). The difference between males and females was not significant (p>0.05). PGC was highly seen in older patients when compared with younger patients (p:000). The average vertical and horizontal dimension of PGC was 2,56±0,98mm and 3,39±1,29 mm respectively. The average total calcified area was 5,45±3,75 mm2. Conclusion: This study did not find any correlation between age, gender, and linear measurements. However, the average calcified are in men was found to be significantly higher than in women.

ABSTRACT Effect of Self-cured Universal Adhesive System on Shear Bond Strengths of Conventional and Bulk-fill Composites Ihsan HUBBEZOGLU1, Serra KUTLU2, Ayşegül KARAARSLAN3 1 Sivas Cumhuriyet University, Faculty of Dentistry, Department of Restorative Dentistry, Sivas, Turkey 2 Niğde Oral and Dental Center, Niğde, Turkey 3 Sivas Oral and Dental Center, Sivas, Turkey Aim: The aim of this study was to investigate the effect of self-cured universal adhesive system on shear bond strengths of two conventional and two bulk-fill composites to dentin. Material-method: In this study, four groups were formed: two conventional condensable composites[G-aenial posterior(GC), Palfique Estelite Paste(Tokuyama)], and two bulk-fill composites[Estelite Bulk Fill Flow(Tokuyama), Beautifil Bulk Restorative(Shofu)]. Each group was divided into two subgroups; G-premio bond (control group) ve self-cured Universal Bond (Tokuyama). 32 human third molar human teeth were prepared to expose dentin surfaces. After the preparation, the teeth were randomly divided into 4 main groups and 2 subgroups (n = 8), composites were applied to the surfaces with the help of cylindrical silicone transparent mold with a diameter of 4 mm and a height of 4 mm. Results: In this study, when both adhesive systems are evaluated; the highest shear bond strength value was Palfique Estelite Paste, while the lowest shear bond strength value was Beautifil Bulk Restorative. While the difference between Palfique Estelite Paste and Estelite bulk-fill flow, Beautifil Bulk Restorative was found to be statistically significant (p<0.05), the difference with G-aenial posterior was not significant (p>0.05). The difference between G-aenial posterior and Beautifil Bulk Restorative was found to be statistically significant (p<0.05). When adhesive systems are compared; G-premio bond was found to be higher in all composite groups compared to self-cured Universal Bond, but the difference between them was statistically insignificant (p>0.05). Conclusion: While conventional composites exhibited high shear bond strengths, bulk-fill composites showed values close to these values. The self-cured adhesive system we used showed near values of shear bond strength to the light-polymerized adhesive system. In terms of bond strength self-cured adhesive systems can be recommended for use in areas where light can be difficult to reach in clinical applications. It is advisable to use self-cured adhesive systems for use in areas where light can be difficult to access in clinical applications.

【摘要】自固化万能胶体系对常规和填充型复合材料剪切粘接强度的影响[ihsan HUBBEZOGLU1, Serra KUTLU2, ay eg l karaarslan] 31土耳其希瓦斯大学牙科学院修复牙科学系，土耳其希瓦斯2 Niğde口腔与牙科中心，Niğde，土耳其希瓦斯3口腔与牙科中心，土耳其希瓦斯目的:本研究的目的是研究自固化万能胶体系对两种常规和两种块状填充复合材料与牙本质剪切结合强度的影响。材料-方法:本研究分为四组:两种常规可凝性复合材料[g - enial posterior(GC)， Palfique Estelite Paste(Tokuyama)]和两种散装填充复合材料[Estelite Bulk Fill Flow(Tokuyama)， Beautifil Bulk Restorative(Shofu)]。每组又分为两个亚组;G-premio bond(对照组)i - self-cure Universal bond (Tokuyama)制备32颗人第三磨牙，暴露牙本质表面。牙体制备完成后，随机分为4主组和2亚组(n = 8)，利用直径为4 mm、高度为4 mm的圆柱形硅胶透明模具将复合材料涂抹在牙体表面。结果:在本研究中，当两种粘接剂体系均得到评价;抗剪强度值最高的是Palfique Estelite膏体，最低的是Beautifil Bulk Restorative。而Palfique Estelite Paste和Estelite Bulk -fill flow与Beautifil Bulk Restorative的差异有统计学意义(p0.05)。G-aenial posterior与Beautifil Bulk Restorative的差异有统计学意义(p0.05)。结论:常规复合材料具有较高的剪切结合强度，体块填充复合材料的剪切结合强度与之相近。我们使用的自固化胶粘剂体系显示出与光聚合胶粘剂体系相近的剪切强度值。在粘合强度方面，自固化粘合剂系统可以推荐用于临床应用中光线难以到达的区域。建议使用自固化粘合剂系统用于临床应用中光线难以进入的区域。关键词:剪切粘结强度，堆填复合材料，自固化胶systemsÖZETGeleneksel ve堆填Kompozitlerin Makaslama Bağlanma Dayanımlarına Işıksız Adeziv Sistemin EtkisiAmaç: Çalışmamızın amacyi, iki geleneksel, iki堆填Kompozitlerin牙质Makaslama bağlanma dayanımlarına ışıksız Adeziv Sistemin etkisinin incelenmesidir。材料-方法:Çalışmamızda iki geleneksel kondanse edilebilen kompozit [G-aenial posterior(GC)， Palfique Estelite Paste(Tokuyama)]， k tlesel yerle tirilebilen iki Bulk - Fill kompozit [Estelite Bulk Fill Flow(Tokuyama)， Beautifil Bulk Restorative(Shofu)] olarak 4 group olu turuldu。她的小组iki alt gruba ayrıldı;g - premium bond (control grubu) ve ışıksız Universal bond (Tokuyama)。32 adet insan üçüncü磨牙insan di牙本质y zeyleri açığa çıkacak ekilde制备edildi。制备yonun ardından di rastele 4 ana, 2 alt gruba ayrıldı(n=8)， y zeylere 4 mm çapında ve 4 mm yüksekliğindeki silindirik silicon effaf kalıp yardımıyla kompozitler uygulandyi。 m grupların makaslama bağlanma değerleri万能测试cihazında ölçüldü， kuvvet birimi ise“牛顿”(=N) olarak calibre edildi。bulbulular: Çalışmamızda her iki adeziv system kullanıldığında da, en y ksek makaslama bağlanma dayanım değerini Estelite Paste gösterirken, en d k makaslama bağlanma dayanım değerini Beautifil Bulk Restorative göstermiştir。Estelite pasteile;容积-填充流量:Beautifil Bulk Restorative arasındaki(统计学分析)(p < 0.05)。G-aenial后ile beaufil Bulk Restorative arasındaki fark统计学差异önemli bulunmu (p < 0.05)。声音:Geleneksel kompozitler, y ksek makaslama bağlanma dayanımları sergilerken, bulkfill kompozitler değerlere yakın değerler göstermiştir。Kullandığımız ışıksız adeziv系统，ışıkla聚合edilen adeziv系统yakın bağlanma değerleri sergilemiuretir。Işıksız adeziv sistemler, klinik kullanımlarda ışığın zor olabileceği bölgelerde bağlanma dayanımı açısından kullanılması önerilebilir。anhtar kelimeler: makaslama bağlanma dayanımı， bulkfill kompozitler， ışıksız adezivler

Each group was divided into two subgroups; G-premio bond (control group) ve self-cured Universal Bond (Tokuyama). 32 human third molar human teeth were prepared to expose dentin surfaces. After the preparation, the teeth were randomly divided into 4 main groups and 2 subgroups (n = 8), composites were applied to the surfaces with the help of cylindrical silicone transparent mold with a diameter of 4 mm and a height of 4 mm.\u0000Results: In this study, when both adhesive systems are evaluated; the highest shear bond strength value was Palfique Estelite Paste, while the lowest shear bond strength value was Beautifil Bulk Restorative. While the difference between Palfique Estelite Paste and Estelite bulk-fill flow, Beautifil Bulk Restorative was found to be statistically significant (p<0.05), the difference with G-aenial posterior was not significant (p>0.05). The difference between G-aenial posterior and Beautifil Bulk Restorative was found to be statistically significant (p<0.05). When adhesive systems are compared; G-premio bond was found to be higher in all composite groups compared to self-cured Universal Bond, but the difference between them was statistically insignificant (p>0.05).\u0000Conclusion: While conventional composites exhibited high shear bond strengths, bulk-fill composites showed values close to these values. The self-cured adhesive system we used showed near values of shear bond strength to the light-polymerized adhesive system. In terms of bond strength self-cured adhesive systems can be recommended for use in areas where light can be difficult to reach in clinical applications. It is advisable to use self-cured adhesive systems for use in areas where light can be difficult to access in clinical applications.\u0000Keywords: shear bond strength, bulk-fill composites, self-cured adhesive systems\u0000ÖZET\u0000Geleneksel ve Bulk-fill Kompozitlerin Makaslama Bağlanma Dayanımlarına Işıksız Adeziv Sistemin Etkisi\u0000Amaç: Çalışmamızın amacı, iki geleneksel ve iki bulk-fill kompozitlerin dentine makaslama bağlanma dayanımlarına ışıksız adeziv sistemin etkisinin incelenmesidir.\u0000Materyal-metod: Çalışmamızda iki geleneksel kondanse edilebilen kompozit [G-aenial posterior(","PeriodicalId":10781,"journal":{"name":"Cumhuriyet Dental Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71343139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
