PURPOSE: To assess a) whether the quality of reporting of randomised controlled trials (RCTs) has improved since the formulation of the Consolidated Standards of Reporting Trials (CONSORT) statement and b) whether there is any difference in reporting of RCTs between the selected public health dentistry journals. MATERIALS AND METHODS: A hand search of the journals of public health dentistry was performed and four journals were identified for the study. They were Community Dentistry and Oral Epidemiology (CDOE), Community Dental Health (CDH), Journal of Public Health Dentistry (JPHD) and Oral Health and Preventive Dentistry (OHPD). A total of 114 RCTs published between 1990 and 2009 were selected. CONSORT guidelines were applied to each selected article in order to assess and determine any improvement since the publication of CONSORT guidelines. The chi-square test was employed to determine any statistical significant difference in quality of reporting of RCTs before and after the publication of the CONSORT guidelines. A comparison was also done to determine any statistically significant difference in quality of reporting of RCTs between the selected journals. RESULTS: Title, abstract, discussion and conclusion sections of the selected articles showed adherence to the CONSORT guidelines, whereas the compliance was poor with respect to the methodology section. CONCLUSION: The quality of reporting of RCTs is generally poor in public health dentistry journals. Overall, the quality of reporting has not substantially improved since the publication of CONSORT guidelines.
PURPOSE: This study was performed to assess the profile of Journal of Dentistry for Children and Pediatric Dentistry journal articles by evidence typology and measure their changes over a thirty-year period (1969-1998). METHODS: All issues of both journals during the study period (1969-98) were manually reviewed. The publications were ranked by the quality of the evidence. Editorials, letters to the editor, abstracts, and organization-related communications were excluded from consideration. The publications were analyzed by journal and also by decade of publication, i.e., 1969-78, 1979-88 or 1989-98. RESULTS: There were 2848 publications included in the data set with descriptive studies, case reports, etc. comprising the majority (71%). No distinctive trends in the evidence typology were detected over the decades in either journal. CONCLUSION: There is a need to improve the quality of the evidence in the two pediatric dental journals reviewed.
There has been an increase in both the quantity and quality of evidence published in Pediatric Dentistry articles between 1999 and 2018 versus the previous three decades (1969 to 1998).
PURPOSE: The objective of this study was to assess the risk of bias of randomized controlled trials (RCTs) published in prosthodontic and implant dentistry journals. MATERIALS AND METHODS: The last 30 issues of 9 journals in the field of prosthodontic and implant dentistry (Clinical Implant Dentistry and Related Research, Clinical Oral Implants Research, Implant Dentistry, International Journal of Oral & Maxillofacial Implants, International Journal of Periodontics and Restorative Dentistry, International Journal of Prosthodontics, Journal of Dentistry, Journal of Oral Rehabilitation, and Journal of Prosthetic Dentistry) were hand-searched for RCTs. Risk of bias was assessed using the Cochrane Collaboration's risk of bias tool and analyzed descriptively. RESULTS: From the 3,667 articles screened, a total of 147 RCTs were identified and included. The number of published RCTs increased with time. The overall distribution of a high risk of bias assessment varied across the domains of the Cochrane risk of bias tool: 8% for random sequence generation, 18% for allocation concealment, 41% for masking, 47% for blinding of outcome assessment, 7% for incomplete outcome data, 12% for selective reporting, and 41% for other biases. CONCLUSION: The distribution of high risk of bias for RCTs published in the selected prosthodontic and implant dentistry journals varied among journals and ranged from 8% to 47%, which can be considered as substantial.
INTRODUCTION: The speed of manuscript publication in reputable journals plays a crucial role in spreading scientific novelties and may influence the number of received citations. In the present study, the authors investigated the publication speed of dentistry journals. This is crucial for both authors, who desire rapid dissemination of their findings, and patients in need, who seek new therapies. MATERIALS AND METHODS: This was a cross-sectional bibliometric analysis of published dentistry journals. A list of dentistry journals featured in the 2021 Journal Citation Report was downloaded. A total of five random original articles were extracted from each of these journals. These articles were published between January and December 2020. Median and interquartile range (IQR) times from submission to acceptance, publication in print, online publication, time from acceptance to in print and online publication were calculated. The correlation between publication times and journal impact factor (IF) was examined. RESULTS: < 0.001) to in-print publication, and IF. There were no correlations between IF and time from submission to acceptance, acceptance to online publication, and submission to online publication. CONCLUSIONS: Publication times availability was revealed to be an indicator of higher impacted journals, which is a potential new exponent of journal quality. Higher IF values were associated with shorter times from submission to acceptance and in-print publication, which is consistent with current editorial policies.
OBJECTIVE: To assess the pattern of instructions regarding the ethical requirements given to authors in various Pediatric Dental Journals. MATERIAL & METHODS: A cross-sectional survey of 'instructions for authors,' for analysis of guidelines on ethical processes, was done. Instructions to authors in journals of pediatric dentistry across the globe were reviewed for guidelines with regards to fourteen key ethical issues. Descriptive statistics were used, and results were expressed in percentages as well as numbers. RESULTS: Of the 18journals of pediatric dentistry, all 14 ethical issues were covered by the instructions to authors in only three journals with only 50% of these providing clarity about authorship using ICMJE guidelines. Furthermore, COI declaration was found to be present as mandatory in about 44% of the journals. 38.9% of the sampled journals mentioned guidelines on research misconduct, publication issues such as plagiarism, overlapping/fragmented publications, and availability of raw research data from authors. Guidelines on handling of complaints about editorial team was provided to authors by slightly over 33% of the selected pediatric dentistry titles while handling of complaints about authors and reviewers were mentioned in 16.7%and 55.6% of the journals respectively. CONCLUSION: A significant proportion of Journals of Pediatric Dentistry did not provide adequate instructions to authors regarding ethical issues.
Objective: The aim of this study was to make a bibliometric analysis of orthodontics articles in national periodical dentistry journals in last 15 years. Material and Methods: In this study, publications were downloaded by scanning the internet archives of the journals of the faculties of dentistry that published regularly in Türkiye between 2005-2020, the Turkish Clinics Journal of Dental Sciences and the Turkish Journal of Orthodontics (TJO). Among the 367 publications published in TJO between the specified years and a total of 4,137 publications in other dental journals included in the study, 408 articles that met the inclusion criteria and a total of 775 publications were examined bibliometrically. Results: In the distribution of orthodontic publications by years, the highest number was between 2010-2014, and when the publications were examined in terms of type, it was seen that the most publications in all journals were original research and the least were case reports. When the publications are examined in terms of the title of the corresponding author, the title of the publications in TJO is Assist. Prof./Dr. Lecturer. It has been determined that the rate of authors with higher education is higher, the university that contributes the most is Gazi University. It was found that the departments which study the most with orthodontics were oral and maxillofacial surgery. Conclusion: As a result, a bibliometric analysis of national and international orthodontics articles are needed in order to examine the essays in the field of orthodontics in terms of different characteristics.
OBJECTIVE: To systematically assess the methodological quality of Systematic Reviews (SRs) and Meta-Analyses (MA) published in Paediatric Dentistry journals and to analyse the relationship between the authors, journals, country, review topic, and the year of publication to the methodological quality of SRs and MA. DESIGN: Paediatric Dentistry journals ranked in the top five of the h5 index of Google Scholar Metrics were selected. SRs with MA were searched independently by two reviewers using PubMed and Scopus databases until December 2017. Methodological quality was assessed using A Measurement Tool to Assess Systematic Reviews (AMSTAR) tool. Statistical significance was set at P < 0.05 and Mann-Whitney U test and Kruskal-Wallis test was employed for comparing the AMSTAR score with the journal characteristics. RESULTS: Finally, 24 SRs with MA were included. The overall AMSTAR score of SRs and MA published in paediatric dentistry journals was 7.08 ± 2.41. No statistically significant differences were found between the country, journal or focus of study to the quality of SRs except the number of authors and the year of publication (P < 0.05). CONCLUSIONS: The quality of SRs and MA in leading Paediatric Dentistry journals were evaluated with AMSTAR tool and areas where quality could be improved were identified.
BACKGROUND: The most-cited papers help to better understand important characteristics of this specific science field. OBJECTIVE: To analyse the 100 most-cited papers in the field of Paediatric Dentistry. DESIGN: A search of the most-cited papers in Paediatric Dentistry journals was performed using journals included in the category of 'Dentistry, Oral Surgery & Medicine' in the Thompson Reuters Web of Science citation indexing database up to December 2018. Two researchers performed the data extraction, which included: number of citations, title, authors, country, year, journals, study design, and thematic area. RESULTS: The number of citations of each paper included in the top 100 most-cited ranged from 42 to 182 (mean: 64.51). Seven papers were cited more than 100 times. Most of the papers were published in the International Journal of Paediatric Dentistry (36%), between 2006 and 2015 (55%), with a cross-sectional design (39%). Twenty-six authors participated in two or more papers. The countries with the highest number of most-cited papers were the United States (25%), Australia (11%), and Brazil (9%). Cariology was the most studied thematic area. CONCLUSION: The evaluation of the top 100 most-cited papers in Paediatric Dentistry journals allowed for a better understanding of the world scenario regarding this research field.
OBJECTIVE: The aim of this contribution is to determine what variables influence the position, by quartiles of the impact factor, as a quality indicator of a journal in the field of Dentistry. METHODS: To this end, 24 journals included in Journal Citation Reports, 6 pertaining to each quartile were selected by a stratified sampling and then an ordinal regression model was estimated stepwise considering the journal impact factor quartile as response variable. RESULTS: The estimation procedure concluded that the average number of papers published yearly by a journal and the percentage of systematic reviews are the most significant variables to be considered, along with the factor representing the journal's degree of adherence to recommendations by the International Committee of Medical Journal Editors. CONCLUSIONS/CLINICAL SIGNIFICANCE: Systematic reviews have significant effect on the Journal Impact Factor position of a journal as well as adherence to ICMJE recommendations, while papers publishing clinical trials bear no influence on this factor. Greater yearly average of published papers in a journal means a higher impact factor.
The resin-modified glass ionomer materials are hybrid materials of traditional glass ionomer cement with a small addition of light-curing resin, and hence exhibit properties intermediate to the two, with some characteristics superior to conventional glass ionomer materials. Generally, they have the advantages of both such as adhesion to tooth structure, esthetics, fluoride release and rapid hardening by visible light. Issues surrounding other physical properties, such as the mechanism of adhesion, sensitivity to water, long-term wear and strength, need to be addressed and substantiated. There are other considerations, which are not features of the conventional materials, but are of importance with the resin-modified glass ionomer cements i.e. light-curing, which require further research to provide evidence of their behavior. The future for this group of materials is unknown, but the currently available materials appear to be promising.
The growing use of NiTi rotary instruments in dental practice demands a good understanding of their concept of alloy and design in relation to improved properties and inherent limitations. Nickel titanium's super elasticity allows more centered canal preparations with less transportation and a decreased incidence of canal aberrations. Furthermore, the production of files with increased taper became possible. This is of special importance because of concerns on the achievement of adequate irrigation and close adaptation of the filling material during endodontic treatment. Unique shaft and tip designs should permit the use of a rotary handpiece allowing different tactile awareness. On the other hand, special attention is paid to maximize cutting efficiency and cutting control throughout instrumentation. NiTi rotary instruments are generally used in a crown-down approach and a continuous reaming motion. Consequently, rounder root canal preparations, with less straightening and a smaller amount of apical extrusion is achievable. In spite of their increased flexibility, separation is still a concern with NiTi files. The phenomenon of repeated cyclic metal fatigue and the variable of torsional loading are two important factors in instrument fracture. However, with awareness of the appropriate manipulation and special attention to the equipment used, NiTi systems are safe with a minimal incidence of instrument failure.
The search for a material to replace amalgam continues as a major quest in materials science. Resin composites may offer one solution but an alternative class of material, the glass ionomer cements (GICs) may have some potential for fulfilling this role. GICs were first introduced to the dental profession in 1976, and have now become an accepted part of the dental armamentarium, especially for use in low load bearing situations. They possess a low coefficient of thermal expansion similar to that of tooth structure, physicochemical bonding to both enamel and dentin, and the release of fluoride ions into the adjacent tooth tissue. These properties help to reduce marginal leakage and may contribute to a reduced incidence of recurrent decay in the restored tooth. Fluoride released into the ambient fluids has a caries-preventive effect in neighboring teeth by enhancing remineralization and inhibiting demineralization of the dental hard tissues. The main criticisms of the GICs are their brittleness, poor surface polish, porosity and surface wear. To overcome some of these deficiencies, considerable attention has been directed at improving their physical properties, especially with the addition of metal powders, the metal-modified GICs. Different metal powders have been tried, including alloys of silver and tin, pure silver, gold, titanium, palladium and stainless steel. There is conflicting data as to whether or not these materials are sufficiently strong for use in high stress restorations, especially their potential use as replacement materials for amalgam fillings.
Since their introduction in the market, some 30 yrs ago, the biocompatibility aspects of glass-ionomer cements (GICs) have been intensively studied. In general, cytotoxicity of fully set conventional preparations in previous studies was shown to be minimal. However, a resin-modified preparation proved to be cytotoxic under these conditions. This product was also observed to be mutagenic, but data in this area are sparse and difficult to interpret. There is also evidence that certain GICs exert some antibacterial properties which is claimed to be related to the fluoride release; however, the mechanisms for this fluoride release are still unclear. Pulp response studies have shown conflicting results. However, unfavorable initial reactions, if present, resolved with time if a bacterial layer under the restoration and pulp exposures were prevented. Pain reactions after cementation of cast restorations with GICs have been reported in the past but there are no such reports in the more recent literature.
Most dental materials permit of microleakage because oral fluids and bacteria commonly gain access to dentin surfaces. Dentin is permeable and allows the bidirectional movement of materials from the oral cavity, across dentin to the pulp and vice versa. The pupal irritation associated with microleakage is often dictated by the permeability of dentin. Thick dentin covered with a smear layer is a better barrier than thin dentin with the smear layer removed, while coronal dentin is more permeable than root dentin. Carious dentin is less permeable than normal dentin, but freshly cut dentin is more permeable than previously prepared dentin. This is partly due to the movement of large plasma proteins from the pulpal blood vessels into dentin. The pulpal circulation contributes to the health of the pulp by supplying nutrients and by removing toxic material that diffuses across dentin via the microcirculation. Thus, there is a delicate balance involving the rate bacterial products diffuse around microgaps between restorative materials and dentin, the rate these materials permeate across dentin and the rate they are removed during pulpal circulation.

OBJECTIVES: The objective of this study was to evaluate the evolution of journal self-citation rates (SCRs) and impact factors (IFs) over time in the dental journals. MATERIALS AND METHODS: The journals listed under the category "dentistry, oral surgery, and medicine" in the Journal Citation Reports for the years 2014-2016 were screened for the following: citations and self-citations to years used in IF calculation, IF, IF without self-citations (corrected IF), SCR, and quartile of the IF distribution the journal occupied (Q1-Q4). Additional data regarding the number of issues published annually, journal's access options, and country of publication were extracted from the "Journal Profile Page." RESULTS: The median SCR significantly declined between 2014 and 2016 (13.725 [0-57.049], 12.687 [0-52.326], and 10.667 [0-53.208], respectively [P < .05]), while at the same time, IFs and corrected IFs significantly increased. SCR was significantly higher in subspecialty journals than that in general journals, as well as in the ones publishing more issues per year. Open-access journals tended to present lower SCR compared to journals requiring payment. No statistically significant differences in SCR were observed with respect to the origin and quartile. Nonsignificant correlations (r < 0.3, P > .05) were found for SCR-IF and SCR-corrected IF for all years. CONCLUSIONS: There was a statistically significant decrease in SCR during the observation period. SCR was not correlated to IF of dental journals. Subspecialty journals and journals publishing more frequently presented significantly higher SCRs. These findings suggest favorable publishing conditions and citation practices in the dental literature.
