Purpose: The study aimed at evaluating the effect of wet and dry polishing systems on the resin composites’ surface roughness and color change. Materials and Methods: In the study, samples were prepared using nanoceramic (Ceram.x one) and nanohybrid (GrandioSO) resin composites. Two different finishing and polishing systems were used in the polishing of resin composites. Resin composite surfaces were finished and polished under wet and dry conditions. The initial surface roughness values (Ra) of the samples were measured using a profilometer, whereas the color changes were measured using a spectrophotometer. Then, the colors of the samples kept in coffee were measured on the 7th and 30th days. Surface roughness and color change values (ΔE00) were measured and statistically analyzed using the one-way analysis of variance (ANOVA) test (P < .05). Results: Wet or dry use of polishing systems did not show a statistically significant difference between the surface roughness values of the resin composite (P < .05). Wet and dry use of polishing systems showed similar color changes on the composite resins (P < .05). Diamond-containing spirals on composite resins showed statistically less color change than aluminum-oxide-containing discs (P < .05). Wet or dry use of polishing systems did not reduce the color change of the composite resins below the acceptability threshold (AT). Conclusion: Wet or dry use of polishing systems on composite resins did not affect surface roughness and color change. The use of diamond-containing polishing spirals that cause less color change can increase clinical success.

Aim: The aim of this study was to evaluate the influence of dentin surface preparation with coarse diamond, extra-fine diamond, and polishing discs on the shear bond strength (SBS) of two resin cements (RCs) to dentin. Materials and Methods: Sixty-six recently extracted human mandibular third molar teeth that were free of cracks, caries, or restorations were collected. Sixty teeth were used for the SBS test. The occlusal part of the crowns was cut to expose mid-coronal dentin. The teeth were divided into three dentin preparation groups: coarse diamond (Meisinger, Germany), extra-fine diamond, and polishing discs (SofLex, 3MESPE, USA), and further conventional RC combined with a self-etch adhesive (Panavia F2.0/ED Primer II, Kuraray, Japan) or self-adhesive RC (Maxcem Elite, Kerr, USA) subgroups (n = 10). Sixty composite resin blocks were prepared (diameter: 3 mm, height: 4 mm) and bonded to the teeth according to the groups. The SBS test was performed with a universal testing device. Six teeth were used for the observation of prepared dentin surfaces and the resin–cement dentin interfaces using field emission scanning electron microscopy (Mira 3 XMU, Tescan). Statistical analyses were performed using the Mann–Whitney U and Kruskal–Wallis tests (P < .05). Results: Panavia F2.0/ED Primer II exhibited significantly higher SBS values for coarse and extra-fine diamond than for the polishing discs (P <.05). Regarding Maxcem Elite, no significant difference was observed for the preparation methods (P > .05). Panavia F2.0/ED Primer II had higher bond strength than Maxcem Elite for the dentin surface prepared with the coarse diamond (P <.05). The differences were not significant for the extra-fine diamond and the polishing disc groups (P > .05). Conclusion: The use of polishing discs did not increase the SBS of the RCs to the dentin.
目的:评价粗金刚石、超细金刚石和抛光盘对两种树脂胶结剂与牙本质剪切结合强度(SBS)的影响。材料与方法:收集66颗近期拔除的无裂纹、无龋、无修复体的人下颌骨第三磨牙。用60颗牙齿进行SBS试验。切掉牙冠咬合部分，露出中冠状牙本质。将牙齿分为三个牙本质制备组:粗金刚石(Meisinger，德国)、超细金刚石和抛光片(SofLex, 3MESPE，美国)，以及常规RC结合自蚀胶(Panavia F2.0/ED Primer II, Kuraray，日本)或自粘RC (Maxcem Elite, Kerr，美国)亚组(n = 10)。制备60个复合树脂块(直径3mm，高度4mm)，按组与牙体粘结。SBS测试采用通用测试设备进行。采用场发射扫描电镜(Mira 3xmu, Tescan)观察6颗牙的牙本质表面和树脂-水泥界面。采用Mann-Whitney U检验和Kruskal-Wallis检验进行统计学分析(P < 0.05)。结果:Panavia F2.0/ED Primer II对粗粒和超细粒金刚石的SBS值显著高于抛光盘(P < 0.05)。Panavia F2.0/ED Primer II对粗金刚石制备的牙本质表面的结合强度高于Maxcem Elite (P . 0.05)。结论:磨光盘的使用并没有增加RCs对牙本质的SBS。

Aim: Intraradicular post systems have become an important treatment method for endodontically treated teeth as they provide retention for restoration to the remaining tooth structure. The objective of the present in vitro study was to evaluate the effect of different fiber post-application techniques on the fracture resistance of premolars with flared root canals and no ferrule. Materials and Methods: Sixty freshly extracted, single-rooted mandibular premolars with no ferrule were endodontically treated by an experienced endodontist, and their root canals were experimentally flared. The specimens with flared root canals were divided into five groups according to fiber post-application techniques (n = 12): a prefabricated fiber post (G1), G1 + two auxiliary posts (G2), i-TFC post system (G3), G1 + quartz splint (G4), and Ribbond (G5). The data were analyzed with analysis of variance and Tukey tests. Results: The findings were revealed that no significant difference was found among four groups, except G5 (P > .05), which demonstrated the lowest fracture resistance (P < .05). G2, G3, G4, and G5 exhibited dominantly restorable fracture pattern, whereas G1 exhibited nonrestorable fracture pattern. Conclusion: Within the limitations of this study, the placement of auxiliary posts, i-TFC post system, quartz splint placement, and Ribbond increased the incidence of restorable fracture compared with the controls.

Aim: Although the shelf life is a key property of dental composites and bonding agents, these materials may often be used in simple procedures after expiration. In this study, the microleakage of two year expired and non-expired dental composites (Filtek Ultimate Universal A2 Enamel, 3M ESPE, USA, and Tetric N Ceram A2, Ivoclar Vivadent, Schaan, Liechtenstein) and a universal bonding system (Single Bond Universal, 3M ESPE, USA) was examined. Materials and Methods: In 40 freshly extracted human molars, two standardized Class II cavities (buccolingual and mesiodistal width of 3 mm and 4 mm, respectively) were prepared (80 cavity preparations). The teeth were thermocycled in distilled water for 1000 cycles in a 5°C to 55°C water bath. Next, the teeth and their apical foramens were coated with water resistant nail varnish, except for 1 mm around the restoration–tooth interface, and retained in a 1% methylene blue solution. After 24 h, the specimens were cut into two halves and analyzed using a stereomicroscope. Scanning electron microscopy images of two samples of the groups were obtained. Results: The Kruskal–Wallis test indicated no significant differences between the groups (P < .05). The occlusal median scores were not significant (P = .99). Moreover, the gingival median scores were not significant (P = .48). No difference was found between the occlusal and gingival values in any group (P > .05). Conclusion: These findings indicated that two-year-expired dental composites and bonding agent, which were maintained under proper conditions, do not have any significant difference in terms of the microleakage.

Aim: The study aimed at evaluating the antibacterial activities of four adhesive systems against three bacterial species in two time periods. Material and Method: Four different antibacterial adhesive materials, a nonantibacterial adhesive (Clearfil SE Bond), and a vancomycin-impregnated antibiogram disc were used in the study. The antibacterial activities of Gluma 2 Bond, Clearfil SE Protect Bond (CPB) Primer, FL Bond II (FLB), and Peak Universal Bond (PUB) on Enterococcus faecalis, Streptococcus mutans, and Lactobacillus acidophilus were evaluated by the disc diffusion method. Antibiogram discs onto which the adhesive agent was dripped were placed on agar plates at intervals. Inhibition zone diameters around the discs, which were incubated, were measured. Statistical analysis was done with the one-way analysis of variance. Results: As a result of our study, it was concluded that the CPB Primer was the agent with the highest antibacterial activity, including the control group. One of the remarkable findings in our study was that CPB Primer showed the most significant effect against Streptococcus mutans among microorganisms. Although not statistically significant, the antibacterial effect of adhesive agents at the end of the 48th h was found to be higher than at the end of the 24th h (P > .05). Conclusion: The strong antibacterial activity of the CPB Primer on all three bacteria suggests that it is a preferable adhesive agent in deep dentinal caries as well as in initial caries lesions.
目的:研究四种胶粘剂体系在两个时间段内对三种细菌的抑菌活性。材料与方法:采用四种不同的抗菌胶粘剂材料，一种非抗菌胶粘剂(Clearfil SE Bond)和万古霉素浸渍的抗生素片进行研究。采用光盘扩散法评价Gluma 2 Bond、Clearfil SE Protect Bond (CPB)引物、FL Bond II (FLB)和Peak Universal Bond (PUB)对粪肠球菌、变形链球菌和嗜酸乳杆菌的抑菌活性。滴入黏合剂的抗生素片每隔一段时间放置在琼脂板上。测定了培养皿周围的抑制带直径。统计分析采用单因素方差分析。结果:我们的研究结果表明CPB引物是抗菌活性最高的药剂，包括对照组。在我们的研究中一个值得注意的发现是CPB引物在微生物中对变形链球菌的作用最为显著。虽然无统计学意义，但粘接剂在48h末的抗菌效果明显高于24h末(P > 0.05)。结论:CPB引物对三种细菌均有较强的抑菌活性，是治疗牙本质深部龋及初发龋的较好粘结剂。

Aim: Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare, highly variable disease with significant oral health impacts. The aim of the study is to examine the existing evidence base surrounding the oral health impacts of APECED and consider the wider clinical significance of the condition relevant to the provision of pediatric dental care. Materials and Methods: The evidence surrounding APECED and the oral health impacts obtained from a review of multiple databases was qualitatively summarized in the form of a literature review. A case study was used to illustrate the relevance of literature in caring patients with APECED. Results: The literature describes a broad range of impacts from APECED, although it is characterized by chronic candidal infection, autoimmune hypoparathyroidism, and Addison’s disease. Oral manifestations of APECED appear frequently and can present early. Developmental defects of the teeth affect a large proportion of patients with APECED and together with candidiasis, characterize the key oral manifestations of the disease. An enhanced preventive and minimally invasive approach to oral health care is recommended for these patients in light of the complexities of their medical condition. Conclusion: Patients with APECED require careful multidisciplinary care to ensure that the optimal oral health outcomes are achieved.

Aim: The aim of this study is to assess the oral health conditions of 8- to 10-year-old students in the mixed dentition stage in Erzurum, Turkey, by determining their dental caries’ status and the soft tissue damages by untreated caries. Materials and Methods: The study was carried out in two randomly selected schools in the residential areas populated predominantly by families with mid-and-low socioeconomic levels. A total of 586 children, 275 girls, and 365 boys with a mean age of 8.95 ± 0.8 participated in the study. Number of decayed, missing due to caries, and filled teeth in the permanent dentition/number of decayed and filled teeth in the primary dentition (DMFT/dft) and visible pulpal involvement (P/p), ulceration caused by dislocated tooth fragments (U/u), fistula (F/f) and abscess (A/a) (PUFA)/pufa indices are included in the clinical examination section of the study. Obtained data were analyzed with SPSS (IBM Corp. 2013, IBM SPSS Statistics for Windows, Version 22.0. Armonk, NY). Results: Our research revealed a DMFT score of 2.43 ± 1.7, dft 4.12 ± 2.7, pufa 0.75 ±1.2, PUFA 0.05± 0.24, a caries frequency of 96.1, PUFA/pufa frequency of 40.9, and untreated caries PUFA/pufa ratio was found as 13.3%. A significant difference with positive correlation was found between d and pufa scores (P < .01). Increasing DMFT, decayed, missing, and filled surfaces (DMFS) in the permanent dentition, and decreasing dft, decayed, and filled surfaces (dfs) in the primary dentition, and pufa scores with the age increment were found to be significant (P < .05). Conclusion: The frequency of soft tissue damage associated with untreated caries, caries index scores, and frequency of dental caries was found to be quite high in the study population consisting of children belonging to families with similar socioeconomic status.

Aim: The aim of this study was to evaluate the effect of desensitizer, temporary cements, dentin cleaning methods on shear bond strength (SBS) of self-etch and self-adhesive resin cements to dentin. Materials and Methods: Four hundred eighty buccal or lingual/palatine coronal portions of human molar teeth were mounted in the acrylic blocks. Teeth surfaces were prepared until the dentin was exposed. Specimens were divided into four groups. One group separated as control and three groups of teeth were treated with a desensitizing agent containing calcium-phosphate desensitizer (Teethmate Desensitizer, TMD), resin-based self-reinforcing monomer (Shield Force Plus, SFP) and 2-hydroxyethyl methacrylate and glutaraldehyde (Gluma Desensitizer). Two different temporary cement containing calcium hydroxide (Dycall) and zinc oxide based (Rely X Temp NE) temporary cement were applied to the dentin surfaces. Temporary cement was removed with one of three cleansing techniques: 2% chlorhexidine digluconate and glass particles containing agent (Consepsis Scrub), cleansing bur (OptiClean), and ıntra/extracoronal rotary brush (Starbrush). All groups were further divided into two cementation subgroups (Panavia V5 and Panavia SA). The SBS (MPa) was measured using a universal testing machine at 0.5 mm/min crosshead speed. The data were analyzed statistically with a four-way analysis of variance and Tukey’s Honest Significant Difference test (α = 0.05). Results: Although SFP showed higher SBS, there was no statistically significant difference between other groups (P > .05). There were no significant differences between temporary cements (P > .05). OptiClean rotary bur showed higher mean SBS values in all groups. The dual-polymerized Panavia V5 showed the highest SBS values in all groups (P <.05). Conclusion: Cleaning of dentin surface from temporary cement remnants with a silicon bur and dual-cure resin cement showed the highest bond strength values.

Aim: The aim of this study was to evaluate the effect of calcium phosphate based desensitizing agent on shear bond strength of self-etch/adhesive resin cements to dentin. Materials and Methods: Eighty dentin specimens were prepared from freshly extracted human third molar teeth and were classified, randomly (n = 20). Half of groups were treated with calcium phosphate based Teethmate Desensitizer and then Panavia V5, RelyX Ultimate (containing self-etch primer), Panavia SA, and RelyX U200 self-adhesive resin cements were luted to all dentin surfaces. All specimens were stored in an incubator at 37°C for 24 h. Shear bond strength was tested by a universal test machine at a 0.5 mm/min crosshead speed. The data were analyzed with a statistical program. Two-way ANOVA was used for statistical differences (P <.05). Dentin surfaces were examined with scanning electron microscopy (SEM) at x5000 and x10000 magnifications. Results: The higher shear bond values were observed in the groups with Teethmate Desensitizer applied and cemented with self-etch (16.05 ± 6.24 and 14.73 ± 4.75), whereas the lowest bonding values were observed in the groups with self-adhesive resin cement without Teethmate Desensitizer (3.73 ± 0.77 and 5.85 ± 4.19; P <.001). As the main effect of the treatment, the bond strength was 9.39 ± 6.04 in the control group, whereas it was 13.49 ± 5.44 in the Teethmate applied groups (P <.05) Conclusions: Calcium phosphate desensitizer did not adversely effected shear bond strength of self-etch/adhesive resin cements to dentin. It even significantly increased the shear bond strength of self-adhesive resin cements.

Aim: Various methods investigating the bacterial content causing periodontal abscesses have been applied in studies conducted until today. However, these studies have focused on periodontopathogens. Our study was carried out to research whether different pathogens other than the known periodontopathogens are present in periodontal abscess formation. Therefore, dominant bacterial samples obtained from the periodontal abscess content using the culture-dependent method were identified by 16S rDNA sequencing. Materials and Methods: Samples were obtained using a syringe or a periopaper from periodontal abscesses of 20 volunteers who met the research criteria. The three different bacterial colonies that were observed most intensely in each sample were selected and purified, and the isolates obtained were kept until the next characterization. Genomic DNA was isolated from each isolate; 16S rRNA genes were amplified by polymerase chain reaction and identified using DNA sequencing analyses. Results: As a result of culture-dependent methods, bacterial species belonging to Streptococcus, Staphylococcus, Neisseria, Actinomyces, Morococcus, Moraxella, and Enterococcus genera were isolated from a total of 60 bacterial isolates, three of which were the most densely growing colonies from each periodontal abscess sample. Conclusion: In our study, most of the bacterial species detected were identified for the first time in the bacterial content of periodontal abscesses. In some previously done studies, most of these bacteria species were shown to cause abscesses in different parts of the body. It was concluded that further studies are needed to determine the number and proportion of these bacteria species in total bacterial content to evaluate whether they cause periodontal abscesses.
