Objectives: The aim of this study was to evaluate the effects of rectal midazolam premedication on hemodynamic parameters and Bispectral Index Scale (BIS) values in children undergoing general anesthesia (GA) for dental rehabilitation. Materials and Methods: Records of 30 children aged 2 to 7 years were retrieved and divided into 2 groups. Group 1 received midazolam 0.3mg/kg body weight rectally and group 2 involved children who did not receive any presedative (control). Mean arterial blood pressure (MAP), heart rate (HR), oxygen saturation (SpO2), and BIS were evaluated for six times; before laryngoscopy(1); 1 min(2); 5 min(3); 10 . . .min after nasotracheal intubation(4); at the time of extubation (5) and at the time of recovery(6). Paired t-test was performed to analyze all data. p<0.05 was defined as statistically significant. Results: MAP and HR did not differ significantly between both groups before laryngoscopy (p>0.05) but increased significantly in control group 1 min after intubation (p<0.04). SpO2 was in the normal range in both groups, which was statistically insignificant (p>0.05). The BIS records of the midazolam group were slightly lower than the control group in general but this difference was insignificant (p>0.05). Conclusions: Midazolam premedication prior to GA induction resulted with lower MAP and HR than the control group 1 minute after intubation whereas it did not alter BIS values remarkably at all time intervals. Therefore, the midazolam sedation did not produce a significant change in reducing GA awareness in children undergoing GA for dental rehabilitation Daha fazlası Daha az

In the last fifty years great strides have been made in implantology. Recently, although implant and bone connection has an acceptable success, complications such as inflammation, fibrosis, thrombosis and infection still remains. With the progression in genetics and tissue engineering, advanced studies are needed. Tissue response of implant-bone contact area must be in a desired level and immune reactions must be promoted for complications to be minimized. Also remodeling or enlargement of alveolar bone for placement of implant becomes possible with tissue engineering.

Objectives: This study evaluated stress distrubitions formed by oblique forces in dental hard tissues, base materials and restorations of endodontically treated permanent mandibular first molars that were restored with different base materials and direct composite restorations by using 3D-FEA method. Materials and Methods: For two different restorative approaches; an MO cavity design and a MOD cavity design was created. Then root canal obturation was modeled. Composite resin (CR), conventional glass ionomer cement (GIC), fiber reinforced composite resin (FRC), resin modified glass ionomer cement (RMGIC), flowable composite (FC), and . . . bulk-fill composite resin (BF) were used as base materials. Von Mises, compressive and tensile stresses in enamel, dentin, base materials and final restoration were analyzed using finite element stress analysis method. Results: Regarding the resulting stresses, CR caused highest stresses and RMGIC caused lowest stresses in enamel, base material, and final restoration. RMGIC caused highest stresses and CR caused lowest stresses in dentin. It was noted that MOD cavity design caused more stress than MO cavity design for all analyzed materials. Conclusions: Materials with elastic moduli similar to dentin; FRC and GIC, may be better choice to avoid high stresses within the tooth and restoration. © 2019 Cumhuriyet University Faculty of Dentistry.Amaç: Bu çalişmada diş sert dokularinda, kaide materyalinde ve restorasyonda oblik kuvvetlerin oluşturduğu stres dağilimlari, farkli kaide materyalleri ve direkt kompozit restorasyonla restore edilen endodontik tedavili daimî mandibular ilk molar dişlerde 3B-SEA metodu ile değerlendirildi. Gereç ve Yöntemler: Iki farkli restoratif yaklaşim için; MO kavite tasarimi ve MOD kavite tasarimi oluşturuldu. Sonra kök kanal tedavisi modellenmiştir. Kompozit rezin (CR), geleneksel cam iyonomer siman (GIC), fiberle güçlendirilmiş kompozit rezin (FRC), rezin modifiye cam iyonomer siman (RMGIC), akişkan kompozit (FC) ve Bulk-Fill kompozit rezin (BF) kaide olarak kullanilmiştir. Von Mises, basinç ve çekme stresleri; mine, dentin, kaide materyalleri ve nihai restorasyonda sonlu elemanlar stres analizi yöntemi kullanilarak analiz edildi. Bulgular: Ortaya çikan stresler ile ilgili olarak; mine, kaide materyali ve nihai restorasyonda CR en yüksek streslere ve RMGIC en düşük streslere neden olmuştur. Dentinde, RMGIC en yüksek strese ve CR en düşük strese neden oldu. MOD kavite tasariminin, analiz edilen tüm materyaller için MO kavite tasarimindan daha fazla strese neden olduğu not edildi. Sonuçlar: Dentine yakin elastik modülüsü olan materyaller; FRCR ve GIC, diş ve restorasyonda yüksek streslerden kaçinmak için daha iyi bir seçenek olabilir. © 2019 Cumhuriyet University Faculty of Dentistry Daha fazlası Daha az

Objectives: The purpose of this study was to determine the oral health status of a group of students with vision impairment and to compare the changes of oral hygiene after oral health education. Materials and Methods: Dental examination of 6-19-year-old of 136 students with vision impairment in a Primary School for Individuals with Vision Impairment in Istanbul was performed. The students were divided into 6-9-year-age group (Group I) and 10-19-year-age group (Group II) and in the first visit, they were examined and their findings were recorded according to DMFT (Decayed, Missing, and Filled Teeth), DMFS (Decayed, Missing, and Fill . . .ed Surfaces) indices of permanent teeth, dft and dfs indices of primary teeth and in the first visit and 3rd follow up period, their Dental Plaque (PI), Calculus (CI) and Oral Hygiene (OHI) Indexes were recorded. They received one-to-one oral health education (OHE). Statistical evaluation was carried out with Wilcoxon and Mann-Whitney U tests and p < 0.05 was found as statistically significant. Results: Regarding the pre and post OHE results of periodontal indexes, PI and OHI scores statistically significantly increased after OHE in Group I (p < 0.05). On the other hand, CI results significantly decreased after OHE in Group II (p=0.042). Comparing post OHE results of PI and OHI, Group I showed statistically significantly higher scores than Group II (p < 0.05). Comparing the difference values of PI and OHI between pre and post OHE, Group I showed statistically significantly lower scores than Group II (p < 0.05). Conclusions: Students with vision impairment have a high prevalence of dental caries and poor oral hygiene. We emphasise the importance of providing proper dental education and regular dental visits to them. © 2019 Cumhuriyet University Faculty of Dentistry.Amaç: Bu çalişmanin amaci, bir grup görme engelli öğrencinin ağiz ve diş sağliği durumlarinin belirlenmesi ve ağiz-diş sağliği eğitimlerinden sonra ağiz hijyenindeki değişikliklerin değerlendirilmesidir.
