Objectives: The aim of this study was to compare the bond strengths of Class V cavities prepared by laser treatment or conventional methods and restored with different adhesive systems. Materials and Methods: Fourty-eight premolars were randomly divided into two groups. In first group, cavities were prepared with Er:YAG laser; in the second group, cavities were prepared with the conventional method. Each group was divided in three subgroups according to the adhesive system (Clearfil Se Bond, Silorane, Futurabond). After termocycled for 1000 cycles, the microtensile test was performed in a universal testing machine. Data were analyze . . .d by two way ANOVA and post hoc Tukey's tests (p<0.05). Result: Results were as follows: Laser-Silorane (21.1±6.92 MPa); Conventional-Silorane (21.09±3.72 MPa); Laser-Futurabond (20.77±5.26 MPa); Conventional-Futurabond (19.01±3.89 MPa); Laser-Clearfil (24.14±5.4); Conventional-Clearfil (28.78±5.98). There are statistically significant differences between the adhesives for the tested parameters (p<0.05). Clearfil Se Bond presented significantly the highest, Silorane and Futurabond presented the lowest, wheras no significant differences were detected between these two (p<0.05). Regardless of the materials used, there were no significant differences between the laser and the conventional cavities.Conclusion: Er:YAG did not significantly improved the bond strength of adhesive systems. The application of Clearfil Se Bond to laser or conventional prepared dentin was found the most effective method Daha fazlası Daha az

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). SpO2was 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

Objective: To compare the effect of Ethylenediamine tetraacetic acid (EDTA) and calcium hydroxide [Ca(OH)2] in the removal of root canal filling material during retreatment procedure. Methodology: Eighty extracted, single-rooted human teeth were used. Root canals were shaped with a crown-down technique using Ni-Ti rotary instruments (ProTaper, Dentsply Maillefer, Switzerland) and filled with a cold lateral condensation method. AH Plus was used as a sealer. After filling, the teeth were divided into 4 groups and root fillings were removed by ProTaper Universal rotary retreatment system. In each group different irrigation and disinfec . . .tion protocols were followed; Group I. Sodium hypochlorite (5.25%) EDTA (17%- 1 min.) Group II. Sodium hypochlorite (5.25%) Group III. Sodium hypochlorite (5.25%) Ca (OH)2 Group IV. Sodium hypochlorite (5.25%) Ca(OH)2 EDTA (17%-1 min.). Irrigation with 17% EDTA was performed only before D3-Retreatment instrumentation in all groups. AutoCAD system was used to detect the amount of residual root canal filling material. The results were statistically analyzed by SPSS (Statistical Package for Social Sciences) for Windows 15.0, one way ANOVA and Tukey's HSD tests. The significance was evaluated at the level of p<0.05. Results: The amount of the remnant filling material in the root canals retreated in Group I was less than the amount of the material in Group II (p<0.01) and Group III (p<0.05). There was no significant difference observed between the other groups in terms of the quantity of the remnant root canal filling materials (p>0.05). Conclusions: Irrigating the canals with EDTA enhanced the removal of root canal filling during retreatment. However, disinfecting the canals with Ca(OH)2 had no effect in the removal of filling material Daha fazlası Daha az

Objectives: To determine the psychomechanical properties of primary teeth dentin surfaces after caries removal with Carisolv™ multimix gel versus conventional drilling methods. Materials and Methods: The dentin surface properties after using Carisolv™ gel and conventional drilling were determined with scanning electron microscope and surface roughness were determined using surface profilometer. Thirty extracted primary molars were sectioned parallel to their vertical axes and Carisolv™ gel was used to remove caries at one side, the other side were cleaned using conventional drilling methods. Results: A decrease at the surface roughn . . .ess values were observed at the samples which Carisolv™ gel was used but this result was not significant. One part that involves occlusal dentinal caries was evaluated. The SEM results of the samples which conventional drill were used revealed no progression of the collagen fibers at the dentinal surfaces and the smear like debris layer were all over the dentinal tubulles so that a uniform and smooth layer were formed. The SEM results of the samples which conventional drill were used revealed that collagen fibrilles showed continuity, no debris layer, more surface roughness and porous layer were formed when comparing with the samples which were treated with Carisolv™. Conclusion: It can be concluded that, the adhesion of the resin based restoration for the teeth treated with Carisolv™ gel would be preferable than the teeth treated with drills Daha fazlası Daha az

Son elli yılda implantoloji alanında büyük adımlar atılmıştır. Günümüzde implantın kemik ile bağlantısı kabul edilebilir derecede başarılı olmasına rağmen inflamasyon, trombozis, fibrozis ve enfeksiyon gibi komplikasyonlar görülebilmektedir. Genetik ve doku mühendisliği alanındaki gelişmelerle birlikte ileri çalışmalara ihtiyaç duyulmaktadır. Görülen komplikasyonları en aza indirmek için implantın yerleştirildiği dokunun yanıtının istenilen düzeyde ve şekilde olması ve immün reaksiyonun düzenlenmesi gerekmektedir. Ayrıca doku mühendisliği ile implantın yerleştirilmesi için, kaybedilen alveolar kemik dokusunun yeniden oluşturulması y . . .a da genişletilmesi mümkün hale gelmiştir. 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 Daha fazlası Daha az

Fusion and gemination are rare occurrences in the mandibular posterior teeth. Different treatment methods can be used according to the situation. The purpose of this case report is to show surgical treatment of these teeth and to prove the exact dental anomaly by examining them histologically. A report of two cases of fused and geminated teeth are presented. The first case was an 42 year old male referred with the complaining of pain originated from the right mandibular third molar fused with a supernumerary tooth. The second case was an 23 year old male having pain in the left mandibular third molar with bifid crown. Both teeth wer . . .e extracted surgically and then cut perpendicular to their long axis to investigate to name the type of the anomaly. The histological examination revealed fusion of cementum between the mandibular third molar and supernumerary fourth molar which is diagnostic for fusion of these teeth in case 1. In case 2, it was observed that the teeth were sharing same pulp chamber which is describing gemination of these teeth. We believe that diagnosing the condition will facilitate endodontic, prosthodontic, periodontic, orthodontic and surgical treatment of such teeth Daha fazlası Daha az

Objectives: New bio-active glass containing toothpaste (NovaMin) is one of the most effective cariostatic products when used as a daily application the aim of this in-vitro study is to evaluate the influence of NovaMin on enamel remineralization. Materials and Methods: Twenty-eight sound human enamel samples were randomly divided into four groups (A-D) each having seven samples as follows: A (Novamin), B (1450 ppm NaF and Novamin), C (CPP-ACP), D (1450ppm NaF). After inducing caries-like lesions, each group was maintained daily for demineralization-remineralization cycle for seven days. During this cycle, samples were treated by the . . . selected toothpaste for each group. Enamel mineral loss was assessed by surface microhardness. Surface enamel microhardness was determined on the enamel blocks. Non-parametric Kruskar-Wallis test compares the amount of surface microhardness recovery (SMHR%) across four different toothpastes. Results: PLM data revealed a mineral precipitation band on the surface layer of all toothpastes; however, when compared to treated lesions, no statistically differences among the groups (p > 0.05) were found. Conclusions: NovaMin containing dentifrice has similar remineralization potential on carious-like lesions when compared to fluoride containing dentifrices. © 2019 Cumhuriyet University Faculty of Dentistry.Amaç: Yeni biyo-aktif cam içerikli diş macunu (Novamin) günlük diş macunu olarak kullanildiginda etkili diş çürügü oluşumunu azaltan ürünlerden birisidir.

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.
