  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: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: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). Panavia F2.0/ED Primer II had higher bond strength than Maxcem Elite for the dentin surface prepared with the coarse diamond (P .05).Conclusion:The use of polishing discs did not increase the SBS of the RCs to the dentin.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  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.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  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.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  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.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  Aim:The present trend in health care is toward the use of natural products for curing diseases. “Propolis” or bees wax is a natural, nontoxic resinous material collected by bees from exudates and buds of the plant. It has many beneficial biological and pharmacological properties such as antimicrobial, anti-inflammatory, antifungal, antiviral, and anticancer activities. Propolis is widely applied in dentistry as an anticariogenic agent, hypersensitivity reducing agent, and endodontic disinfection to name a few. The diverse phytochemical constituents of propolis are responsible for its valuable properties. Considering its vast potential, propolis has gained the attention of many researchers. The aim of this study is to offer a comprehensive evidence which will enable the readers and researchers to appreciate the prospects of the application of Indian propolis in present-day dentistry.Material and Methods:In vitro and in vivo studies on Indian propolis and its application in dentistry searches were performed in PubMed, Scopus, and Cochrane library databases up to December 2020.Results:The search identified 31 records; 12 full-text articles which met the eligibility criteria were assessed. Based on the results of in vitro studies, further in vivo studies need to be carried out to prove the feasibility of Indian propolis as an anticariogenic agent, a desensitizing agent, and an intracanal irrigant/medicament in the field of dentistry.Conclusion:Indian propolis has shown an immense amount of potentiality which demands for more clinical research to have sufficient evidence-based literature for future usage in oral health care.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  Aim:To compare following the Cuban Revolution, Cuba’s economy and civil society was transformed by the initiation of a program of nationalization and political consolidation. The Cuban government operates a national health system and assumes fiscal and administrative responsibility for the healthcare of its citizens. Other industrialized nations continue to surpass the US in health-related outcomes indicating areas of improvement in its healthcare system. Assessing the successes and failures as well as the advantages and disadvantages of other countries’ healthcare systems may be instrumental in the development of modifications to the organization and delivery system of healthcare in the US. This paper aims to report the information attained from previous literature as well as from first-hand observations from a public health trip to Cuba in order to compare the healthcare systems in Cuba and the United States.Materials and Methods:A group of New York University College of Dentistry faculty and students traveled to Cuba in April 2019 for professional research and professional meetings (CFR 515.564). While in Cuba, the researchers took written notes of the lecture-based material and conversations. Upon return to the United States, published literature was searched for the collection of any additional data and all qualitative data and quantitative data was compiled and organized. Since 1959, Cuba has made continuous adjustments and improvements to its universal, free and accessible healthcare system.Results:There have been notable improvements to the country’s public health status, such as the implementation of an immunization program and subsequent eradication of communicable diseases, such as polio and rubella. Additionally, the implementation of the National Program on Dentistry guarantees dental care to all Cuban children under the age of 19. Today, the Cuban National Health System (NHS) initiatives have evolved to combat the novel coronavirus (COVID-19) pandemic.Conclusion:Recognizing the advantages as well as the disadvantages of the Cuba’s National Health System (NHS) would be useful for future policymakers in the United States. Cuban approaches to health could be tailored to the United States environment to improve healthcare effectiveness and population health status in the future.

  Aim:This study reviews the importance of selecting implant systems with connection designs that ensure better long-term prognosis of the prosthesis, thus placed.Materials and Methods:An electronic search on the PubMed database was done using MeSH keywords (“dental implant OR abutment OR connection AND microleakage OR bone loss”) to review English language articles published since the year 2011, which compared the crestal bone levels and microleakage around various implant–abutment connection designs (external hex, internal hex, and Morse taper). The search screened for articles on human trials and in vitro studies to be included within the review.Results:Based on the inclusion and exclusion criteria applied to the preliminary search, a total of four articles were included in the review for evaluating the influence of connection type on peri-implant bone loss, while nine articles were included to study the influence on bacterial leakage across the implant–abutment interface.Conclusion:Based on the studies reviewed, the conical connection design proved to be the most biologically stable junctional geometry because of the better microbial seal and the lesser micromovement observed in these types of implants during functional loading. Moreover, this review even emphasizes the need for more longitudinal clinical trials to assess the microbial seal of these connection designs within the actual oral environment to evaluate long-term changes in the peri-implant tissues, and subsequently even factor the prognosis of the planned prosthetic intervention.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  Aim:One of the main steps in a successful endodontic treatment is determining the correct working length (WL) of the root canal. In this regard, electronic apex locators (EAL) have been widely used for measuring the WL. The accuracy of EALs in determining the WL may be influenced by various factors. This study is aimed to evaluate the effects of apical patency, coronal preflaring, and calcium hydroxide on the accuracy of the EAL.Materials and Methods:In this in vitro study, 20 central incisor single-rooted human teeth with fully formed apex were considered. Then, samples were randomly divided into two study groups, ten samples in each group. The WL was determined and recorded at 0.5 mm distance to the apex using Root ZX apex locator before and after creating patency, coronal preflaring, and calcium hydroxide administration. All WLs were measured separately for each tooth and reviewed independently by two experienced operators with extensive experience in using EALs. Paired t test and Wilcoxon signed-rank test were applied and the significant level was at .05.Results:Statistical analysis of the obtained data showed a significant decline in the WL after apical patency and coronal preflaring (P < .05). Moreover, WL exhibited a significant enhancement after calcium hydroxide application (P < .05).Conclusion:Apical patency and coronal preflaring increased the accuracy of apex locators in determining the WL of the teeth. Besides, calcium hydroxide residues in the root canal reduced the accuracy of the apex locator.

  Aim:To compare new design implant-supported removable partial dentures retained with anterior fixed prosthesis with a conventional locater and bar attached implant overdenture prostheses retained by two or four implants via photoelastic stress analysis.Materials and Methods:Seven edentulous mandibuler acryclic models prepared and divided into two main groups; two to four implant models, subgroup separation as stated; for two implant models overdenture with locator attachment, crown design retained removable prosthesis with clasp retention, bridge design retained removable prosthesis with clasp retention, bridge design retained removable prosthesis with precision attachment retention; and for four implant models prosthesis with bar attachment overdenture, fixed bridge design retained removable prosthesis with clasp retention, fixed retained removable prosthesis with precision attachment retention. A 300 N load was applied to the first premolars. Photoelastic stress analysis method that is a specific method concerning stress visualization, and does not require statistical analysis, was used. The stress distributions were seen in optically using a poloriscope.Results:In the models with two implant-retained removable partial dentures, the stress distribution was found to be lower than that with the four implant-retained removable partial dentures. Nonsplinted implants caused high stress around the distal implant on the loading side.Conclusion:The stress loads were transmitted to other implants by splinting. Implant-supported removable partial dentures with an anterior fixed prosthetic design show lower stress distributions compared with bar retained prosthesis. These dentures appear to be advantageous in terms of stress transmission.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  Aim:The aim of this study was to compare the effectiveness of different filling materials and obturation techniques for root canal obturation in primary teeth.Materials and Methods:Eighty maxillary primary incisors were included in this in vitro study. After biomechanical preparation, all samples were scanned using microcomputed tomography (micro-CT) and root canal volumes were calculated. Samples were grouped according to filling materials and obturation techniques, with ten samples in each group. The samples were filled with zinc oxide eugenol (ZOE) and Vitapex using four different obturation techniques (local anesthesia syringe, lentulo spiral, pastinject, and lentulo spiral–ultrasonic activation). After filling, samples were scanned a second time using micro-CT and root canal volumes were calculated. The statistical analysis was performed using SPSS version 24.0. Data were analyzed by Kruskal–Wallis and Mann–Whitney U tests.Results:When the ZOE and Vitapex were compared, it was observed that there were no significant differences between their postobturated volumes, percentage obturated volume (POV), internal void (IV), and percentage of internal void volume (PIV) (P > .05). The local anesthesia syringe group had a significantly lower postobturated volume and POV, and a significantly higher IV and PIV for both filling materials than that by the other groups (P < .05). There was no significant difference between the other obturation techniques (P > .05). For the local anesthesia syringe group, postobturated volume and POV were significantly higher and IV and PIV were significantly lower with Vitapex than with ZOE (P < .05). There was no significant difference between the other obturation techniques filled either with ZOE or Vitapex (P > .05).Conclusion:Except for the syringe technique, no difference was observed between the ZOE and Vitapex materials. The syringe technique used in the primary root canal filling was less effective than the other techniques, which had similar efficacy, and in this technique, more effective canal filling was achieved with Vitapex.

  Aim:To investigate the effect of sodium ascorbate (SA), an antioxidant and calcium hydroxide (Ca(OH)2), a buffering agent mixture, on the shear bond strength of a luting resin to dentin, and pH changes of the extraradicular medium solution after intracoronal bleaching with hydrogen peroxide.Materials and Methods:In this in vitro study, 60 human maxillary central incisors were randomly assigned into six groups (n: 10): Group 1: restored, no bleach; group 2: bleached, bonded immediately; group 3: bleached, treated with 10% SA applications before bonding; group 4: bleached, treated with calcium hydroxide applications before bonding; group 5: bleached, treated with CaOH2 and SA mixture applications before bonding; group 6: delay bonding by seven days. For bleach treatment in groups 2 to 6, intracoronal bleaching was performed with 35% hydrogen peroxide for four days. SA or CaOH2 or mixture of SA and CaOH2 were left in the access cavity for four days. Hybrid blocks, 4 mm × 4 mm wide × 2–mm thick, were luted with resin cements on dentin surface and then the specimens were subjected to shear bond strength testing. Analysis of variance and Tukey post hoc multiple comparison tests were applied (P < .05).Results:G2 and G4 showed significantly low bond strength values and they were lower than the other groups (P < .05). There were no significant differences between G1, G3, and G6 (P > .05). The pH values had risen markedly in the groups containing calcium hydroxide (G4 and G5) after four days (P < .05).Conclusion:The application of 10% SA or 10% SA and CaOH2 mixture were effective at reversing bleaching effects on bond strength. CaOH2 or CaOH2 and 10% SA mixture increased the external medium pH and were effective for alkalinization after intracoronal bleaching.

  Aim:The aim of this study was to evaluate the effect of different cooling times on shear bond strength between cobalt–chromium metal frameworks fabricated by different techniques and veneering porcelain.Materials and Methods:One hundred twenty cobalt–chromium metal ceramic samples were obtained by three different techniques (casting, milling, and laser sintering). During the porcelain firing, fast and slow cooling protocols were applied. Ten specimens from each group were determined for all groups. The shear bond strength of the metal ceramic samples was measured by a universal testing machine with a constant crosshead speed of 0.5 mm/min. One sample from each group was evaluated by the scanning electron microscopy analysis in terms of surface change and fracture morphology. Variance analysis and Tukey test were used to analyze statistically significant differences between groups.Results:It was seen that the difference between the bond strengths of the metal frameworks obtained by different techniques was statistically significant (P < .05). All groups except for difference between the bond strengths of all the frameworks metal groups with G-Ceram porcelain were statistically significant (P < .05). The best bond strengths that were statistically significant were fast cooling G-Ceram (19.65 ± 2.65 MPa) with metal frameworks fabricated by laser sintering, fast cooling with metal framework fabricated by milling Noritake (19.17 ± 2.91 MPa), and the metal framework fabricated by casting was found to be slow cooling Noritake (12.99 ± 2.08 MPa) were seen.Conclusion:The porcelain cooling times had significant effect on the shear bond strength of porcelain to casting, milling and laser sintering alloys.

  Aims:To evaluate the color changes that occur after accelerated aging in feldspathic ceramic crowns cemented with three different dual-cured resin cements.Materials and Methods:For each of the A2-colored RelyX U200, G-CEM LinkForce, and Panavia V5 cement groups, 45 dies from A2-colored zirconia blocks and 45 crowns from CEREC blocks were prepared. Color measurements after 24 h of cementation (T1) and after cycles of aging of 1750 (T2), 3500 (T3), and 7000 (T4) in the thermal cycle device were made using SpectroShade Micro device. The coordinates of the color were used L*, a*, and b* as base and the color change was calculated with ∆E00 in determining the color. One-way analysis of variance test was used to compare the times in terms of ∆L*, ∆a*, and ∆b* values.Results:It was found that ∆L* value decreased significantly in period of the T2, T3, and T4 times compared to T1 in all groups (P < .05), whereas the change between period of T2, T3, and T4 times was not significant (P > .05). The ∆a* value increased significantly in the period of T3 and T4 times compared to T1 in the only G-CEM LinkForce group, whereas the ∆b* value increased significantly in the period of T4 time compared to T1 in the only Panavia V5 group. The changes in ∆E00 values, which were observed in all period of times, were found to be between 0.43 and 1.04, 0.43 and 1.43, and 0.40 and 0.97 in RelyX U200, G-CEM LinkForce, and Panavia V5 groups, respectively.Conclusion:After accelerated aging, it was found that the color of all cements became darker and the G-CEM LinkForce group turned red and the Panavia V5 group turned yellow. However, it was found that the color changes that occurred were within clinically acceptable visible levels.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  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.

  Abstract: Journal of Advanced Oral Research, Ahead of Print.
  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
