Abstract
OBJECTIVES This study evaluates the endorsement of open science practices by dental journals. MATERIALS AND METHODS This was a meta-research study that included journals listed in the 2021 Journal Citation Reports under Dentistry. A comprehensive evaluation was performed by accessing journal websites to ascertain the availability of publicly accessible instructions to authors in Portuguese, English, or Spanish. A researcher extracted information from the "Instructions for Authors" section, encompassing the journal's impact factor, mention of any reporting guidelines, details on data sharing, acceptance of articles in preprint format, and information regarding study protocol registration. Descriptive data analysis was conducted using the Stata 14.0 program, and an Open Science Score (OSS) (ranging from 0 to 100 %) was calculated for each journal by considering five open science practices. Pearson's correlation test was conducted to determine the relationship between the OSS score and journal impact factor. RESULTS Ninety journals were included in the study. Most journals (70 %) indicated the mandatory use of reporting guidelines, while 60 % recommended data sharing. Conversely, 46.7 % did not provide information on study protocol registration, and 44.4 % stipulated them as mandatory for authors. Regarding preprints, 50 % of the journals did not provide any information, but 46.7 % confirmed their acceptance. The mean OSS was 52.9 % (standard deviation 26.2). There was a weak correlation (Pearson's correlation coefficient of 0.221) between the journal impact factor and OSS (P-value=0.036). CONCLUSION This study found varying degrees of endorsement of open science practices among dental journals. CLINICAL SIGNIFICANCE Dental practitioners rely on high-quality, evidence-based research for informed decision-making. By assessing the endorsement of open science practices, our study contributes to improving the quality and reliability of dental research, ultimately enhancing the evidence base for clinical practice.

Abstract
The integration of dentistry into primary health care is crucial for promoting patient well-being. However, clinical studies in dentistry face challenges, including issues with study design, transparency, and relevance to primary care. Clinical trials in dentistry often focus on specific issues with strict eligibility criteria, limiting the generalizability of findings. Randomized clinical trials (RCTs) face challenges in reflecting real-world conditions and using clinically relevant outcomes. The need for more pragmatic approaches and the inclusion of clinically relevant outcomes (CROs) is discussed, such as tooth loss or implant success. Solutions proposed include well-controlled observational studies, optimized data collection tools, and the integration of artificial intelligence (AI) for predictive modelling, computer-aided diagnostics and automated diagnosis. In this position paper advocates for more efficient trials with a focus on patient-centred outcomes, as well as the adoption of pragmatic study designs reflecting real-world conditions. Collaborative research networks, increased funding, enhanced data retrieval, and open science practices are also recommended. Technology, including intraoral scanners and AI, is highlighted for improving efficiency in dental research. AI is seen as a key tool for participant recruitment, predictive modelling, and outcome evaluation. However, ethical considerations and ongoing validation are emphasized to ensure the reliability and trustworthiness of AI-driven solutions in dental research. In conclusion, the efficient conduct of clinical research in primary care dentistry requires a comprehensive approach, including changes in study design, data collection, and analytical methods. The integration of AI is seen as pivotal in achieving these objectives in a meaningful and efficient way.

Abstract
OBJECTIVES New scientific knowledge is not always available to decision makers. Policy briefs are a way that dental researchers can communicate research findings to policymakers. This study compares usefulness of 2 types of policy briefs about sugar-sweetened beverage (SSB) intake and tooth decay. METHODS We developed 2 policy brief types (data focused and narrative focused) and emailed a randomly assigned policy brief to 825 policymakers and staff from 3 levels of government (city, county, and state) in Washington State. Participants completed a 22-item online questionnaire. There were 4 study outcomes: whether the brief was understandable, whether the brief was credible, likelihood of use, and likelihood to be shared (each measured on a 5-point Likert-like scale). The t test was used to evaluate whether outcomes differed by policy brief type and government level (α = 0.05). RESULTS There were 108 respondents (adjusted response rate 14.6%). About 41.6% of participants were in city government, 26.9% were in county government, and 29.6% were in state government. Participants reported that both data- and narrative-focused briefs were understandable (mean rating [MR] and standard deviation [SD]: 4.15 ± 0.68 and 4.09 ± 0.81, respectively; P = 0.65) and credible (MR and SD: 4.13 ± 0.70 and 4.09 ± 0.70, respectively; P = 0.74), but they were not likely to use (MR and SD: 2.71 ± 1.15 and 2.55 ± 1.28, respectively; P = 0.51) or share it (MR and SD: 2.62 ± 1.04 and 2.66 ± 1.30, respectively; P = 0.87). The likelihood of sharing briefs differed significantly by level of government (P = 0.017). Participants at the state level were more likely to share information from the briefs (mean rating and SD: 3.10 ± 0.80) than city- and county-level participants (MR and SD: 2.62 ± 1.27, and 2.24 ± 1.21, respectively). CONCLUSION Both data- and narrative-focused policy briefs may be a useful way to communicate dental research findings to policymakers, but additional steps are needed to ensure that briefs are used and shared. KNOWLEDGE TRANSFER STATEMENT Researchers should disseminate their research findings to maximize scientific impact. Our study findings indicate that policy briefs may be a useful way to communicate dental research findings to policymakers, but additional research is needed on the best ways to disseminate findings.

Abstract
AIM To assess the status quo of outcome measures used in treatment studies in Endodontics, and potentially identify strategies for improvement, by (i) systematically assessing the outcome measures using a conceptual model and (ii) comparing these with measures used in corresponding studies in the adjacent fields. METHODOLOGY The International Endodontic Journal, Caries Research, The Journal of Clinical Periodontology and The Journal of Oral & Facial Pain and Headache were selected to cover four adjacent dental disciplines. In each journal, the 50 most recent consecutive publications fulfilling inclusion criteria were included. A hierarchical model for diagnostic imaging studies was modified to assess studies related to treatment. The model comprised six levels, with technical as the lowest level and societal as the highest. Extracted data included study origin, study type, and identified outcome measures. Fisher's Exact Tests with Bonferroni corrections compared studies. p < .05 was considered statistically significant. RESULTS Amongst 756 publications, the 200 most recent studies matching the inclusion criteria were identified. Less than half (36.5%) assessed the clinical, patient, or societal aspects of treatment; 10.0% in International Endodontic Journal, 28.0% in Caries Research, 38.0% in Journal of Clinical Periodontology, and 70.0% in Journal of Oral & Facial Pain and Headache (p < .001). CONCLUSIONS According to included publications, research on treatment within the endodontic field is mainly focusing on technical and biological outcomes. The benefits of patients and society were less frequently examined than in corresponding journals in adjacent disciplines. When designing studies, including higher-level outcomes should be considered.

Abstract
OBJECTIVES Low-frequency, low-intensity ultrasound is commonly utilized in various dental research fields to remove biofilms from surfaces, but no clear recommendation exists in dental studies so far. Therefore, this study aims to optimize the sonication procedure for the dental field to efficiently detach bacteria while preserving viability. MATERIALS AND METHODS Initial biofilm was formed in vivo on bovine enamel slabs (n = 6) which were worn by four healthy participants for 4 h and 24 h. The enamel slabs covered with biofilm were then ultrasonicated ex vivo for various time periods (0, 1, 2, 4, 6 min). Colony-forming units were determined for quantification, and bacteria were identified using MALDI-TOF. Scanning electron microscopic images were taken to also examine the efficiency of ultrasonications for different time periods. RESULTS Ultrasonication for 1 min resulted in the highest bacterial counts, with at least 4.5-fold number compared to the non-sonicated control (p < 0.05). Most bacteria were detached within the first 2 min of sonication, but there were still bacteria detached afterwards, although significantly fewer (p < 0.0001). The highest bacterial diversity was observed after 1 and 2 min of sonication (p < 0.03). Longer sonication periods negatively affected bacterial counts of anaerobes, Gram-negative bacteria, and bacilli. Scanning electron microscopic images demonstrated the ability of ultrasound to desorb microorganisms, as well as revealing cell damage and remaining bacteria. CONCLUSIONS With the use of low-frequency, low-intensity ultrasound, significantly higher bacterial counts and diversity can be reached. A shorter sonication time of 1 min shows the best results overall. CLINICAL RELEVANCE This standardization is recommended to study initial oral biofilms aged up to 24 h to maximize the outcome of experiments and lead to better comparability of studies.

Abstract
This study aimed to analyze the 100 most-cited papers in Dentistry, with a focus on female leadership in dental research. Papers were retrieved from the Web of Science Core Collection (WoS- CC) in the category 'Dentistry, Oral Surgery & Medicine'. Gender was assessed through WoS-CC, Scopus, ResearchGate, social media, institutional websites, and software that assigns gender according to first names (https://genderapi.io). Characteristics of authors in leadership roles were retrieved, such as affiliation, publication history, citations, H factor, and i500. The 100 most-cited papers in Dentistry were authored by 394 researchers, 326 (82.7%) men, and 68 (17.3%) women - there were 4.8 male authors for each female. Among the lead authors, there were 11.3 males for each female. Among female senior authors, there were 7 males for each female. Among lead/senior authors of the 100 most-cited papers (first and last authors, respectively), 18 were women. There was an increase in the participation of women in the top cited papers regardless of authorship role across the six decades, with a peak of two female authors in the first decade of the 21st century. For female authors in leadership roles, their publication history shows the time between their first and last papers in WoS-CC ranged from 4 to 42 years for lead authors and 1 to 39 years for senior authors. Women were found to be largely underrepresented as leaders of the 100 most-cited papers, highlighting pervasive gender inequalities in dental research publications.

Abstract
OBJECTIVES Our aims are to describe the characteristics of dentists, members of the US National Dental practice-based research network (PBRN) in the United States, and determine how often these dentists provide specific dental procedures. METHODS Dentists completed a questionnaire when they enrolled in the Network about their demographic and training characteristics and characteristics of their practices and patients. Dentists also reported the frequency of providing specific dental procedures. Data were analyzed using descriptive statistics. RESULTS Of 4,483 dentists in active clinical practice, 34% identified as females, 70% as white, and 73% as general dentists. Most dentists practiced in large metropolitan areas (87%) and in solo or small practices (72%). On average, they reported about one-half of their patients were children or older adults, a third were from historically underrepresented racial and ethnic groups, and one-quarter were covered by public insurance. Most dentists routinely performed restorations and fixed prosthetics (78%), extractions (59%), removable (44%) and implant (40%) prosthetics, and endodontics on incisor and premolar teeth (44%). CONCLUSIONS Dentists participating in the National Dental PBRN have much in common with dentists at large. The network has a broad representation of dentists, practice types, patient populations, and treatments offered, including diversity regarding race/ethnicity, gender, insurance, and geography of its practitioners and patients. CLINICAL SIGNIFICANCE Characteristics of National Dental PBRN dentists suggest that a broad range of dentists is interested in participating in national-level research studies, thereby enabling an array of clinical study settings and topics that can optimize the generalizability of study findings.

Abstract
BACKGROUND The first steps towards gender equity in science are measuring the magnitude of inequity and increasing awareness of the problem. OBJECTIVES To describe trends in gender disparities in first and last authorship in the most cited dental publications and general dental literature over a 20-year period. METHODS Articles and bibliometric data were retrieved from the Scopus database for the period 1996 to 2015. Two groups of 1000 articles each were retrieved: a random sample and another sample of top-cited articles for each year. The gender of the first and last author of each publication was manually identified. When this was not possible, we used an online software platform (https://genderize.io/). Descriptive analyses identified the proportion of women first and last authors in both samples, stratifying by dental discipline and geographic region. Trends were ascertained by frequency metrics across years. Gender disparity was observed in both first and last authorship, with a larger gap being observed in the top-cited sample. RESULTS Women led 28.4% and 20.3% of articles in the random and top-cited samples, respectively. A similar pattern was observed for the last authorship group (22.1% and 16.1%, respectively). An increasing trend in the proportion of articles led by women over time was observed in both samples. This increase was larger in the top-cited sample (from 15.0% in 1996-2000 to 25.1% in 2015) than in the random sample (from 26.3% in 1996-2000 to 33.2% in 2011). CONCLUSIONS Clear gender disparities in dental research publications in the last 20 years were identified in both general and top-cited manuscripts, across dental disciplines, across countries, across first and last authorship, and over time. It is paramount that actions are taken to attract, retain and promote women in science, as well as to monitor and ensure progress towards gender equity.

Abstract
Time-to-event (survival) analysis is an integral tool in the wheelhouse of the dental researcher. While there are many references available for the study of time-to-event analysis, they tend to be written for audiences trained in statistical methodology. Moreover, the canonical examples offered by most time-to-event analysis references are focused on outcomes that do not translate directly to dentistry. This article provides a tutorial of time-to-event analysis for the specific context of dental research. Our tutorial assumes no statistical training or computing experience. Using real data from a dental study as our extended example, we explain foundational concepts, including median survival, Nth-year survival, the log-rank test, and the Cox model.

Abstract
BACKGROUND To achieve the ultimate therapeutic reality of disease prevention, we must first conduct a thorough review of periodontal and peri-implant diseases concomitant with their mechanistic, predisposing, and precipitating factors to address the present oral/systemic needs of our patients. METHODS An innovative dental research patient data repository (RPDR) named BigMouth was successfully launched in August 2012 with data on more than 4.5 million patients seen in 11 dental schools (members of the Consortium of Oral Health Research and Informatics, COHRI). RESULTS Level 1 data access allots researchers with count data that may be used to formulate and test initial hypotheses based on preliminary data trends. Level 2 access gives more detailed, patient-level information with full periodontal charts. Of note, radiographic data were not accessible at the time of writing this manuscript. CONCLUSION As we support the use of these innovative "big data" tools for exploratory use, we bring to the forefront the purposeful intention to (1) not overproject unsubstantiated relationships and (2) simultaneously pursue grounding of the mechanistic underpinnings of found associations.

Abstract
OBJECTIVE The use of phrases such as "data/results not shown" is deemed an obscure way to represent scientific findings. Our aim was to investigate how frequently papers published in dental journals use the phrases and what kind of results the authors referred to with these phrases in 2021. METHODS We searched the Europe PubMed Central (PMC) database for open-access articles available from studies published in PubMed-indexed dental journals until December 31st, 2021. We searched for "data/results not shown" phrases from the full texts and then calculated the proportion of articles with the phrases in all the available articles. From studies published in 2021, we evaluated whether the phrases referred to confirmatory results, negative results, peripheral results, sensitivity analysis results, future results, or other/unclear results. Journal- and publisher-related differences in publishing studies with the phrases in 2021 were tested with Fisher's exact test using the R v4.1.1 software. RESULTS The percentage of studies with the relevant phrases from the total number of studies in the database decreased from 13% to 3% between 2010 and 2020. In 2021, out of 2,434 studies published in 73 different journals by eight publishers, 67 (2.8%) used the phrases. Potential journal- and publisher-related differences in publishing studies with the phrases were detected in 2021 (p = 0.001 and p = 0.005, respectively). Most commonly, the phrases referred to negative (n = 16, 24%), peripheral (n = 22, 33%) or confirmatory (n = 11, 16%) results. The significance of unpublished results to which the phrases referred considerably varied across studies. CONCLUSION Over the last decade, there has been a marked decrease in the use of the phrases "data/results not shown" in dental journals. However, the phrases were still notably in use in dental studies in 2021, despite the good availability of accessible free online supplements and repositories.

Abstract
OBJECTIVE To analyse characteristics of literature related to dental research and education published in a single medical journal, The Journal of Pakistan Medical Association. METHODS The bibliometric study was conducted at the Sindh Institute of Oral Health Sciences, Jinnah Sindh Medical University from March till May 2020, and comprised electronic and hand search of scientific literature relevant to dentistry published in the Journal of Pakistan Medical Association from the first issue published in 1953 till March 2020. The selected articles were analysed for year of publication, field of study, type of article, institute and country of first author, number of authors and citation count. Keyword mapping was also carried out. Data was analysed using SPSS 19. RESULTS Of the 159 articles identified, 117(73.6%) were contributed from Pakistan. The most common specialties were Oral and Maxillofacial Surgery and Epidemiology with 20(12.6%) articles each, followed by Operative Dentistry and Endodontics 19(11.9%). Majority of articles were Original / Research 87(54.7%). The highest number of articles were published in 2019 26(16.35%). The Aga Khan University, contributed the most publications 30(18.9%), followed by Dow University of Health Sciences, 11(6.9%). Majority of the articles were contributed by three authors 48(38.4%). The top cited article was found to have 113 citations, followed by articles with 103 and 91 citations. CONCLUSIONS The contribution of scientific papers related to dentistry and dental education in the Journal of Pakistan Medical Association was significant. With growth of dentistry as a discipline along with a parallel increase in the publication of dental research papers, it is imperative that a dedicated indexed journal for dental research be commenced.

Abstract
Objectives Women in oral health science face similar societal issues and challenges as those in other STEMM careers, and gender disparities continue to exist as evidenced by fewer women represented as first and last authors in scientific publications. Pre-prints may serve as a conduit to immediately disseminating one’s work, bypassing the arduous peer review process and its associated inherent biases. Therefore, the purpose of this study was to 1] compare the gender of first and last authors in pre-print versus peer reviewed publications, 2] examine the composition of first and last author pairs as stratified by publication type, and 3] examine the correlation between woman authorship and institutional geographic location and publication metrics stratified by publication type. Methods The keyword “oral health” was used to search for publications in BioRxiv and Pubmed in the years 2018 and 2019. Gender of first and last authors were determined, and its frequency was considered as the primary outcome. Additionally, the geographic location of the author’s associated institution and publication metrics measured by Altmetrics score were extracted. Data was descriptively summarized by frequencies and percentages. Chi-square analysis was conducted for categorical variables which included the relationship between gender and publication type as well as gender and region of author’s associated institution. Binomial regression analysis was conducted to analyze the relationship between gender and Altmetrics. Results Woman first authors comprised 40.3% of pre-prints and 64.5% of peer reviewed publications [p<0.05]. Woman last authors comprised 31.3% of pre-prints and 61.5% of peer reviewed publications [p<0.05]. When analyzing the relationships between first and last author, the Man-Man pairing represented 47.7% of the pre-print publications and the Woman-Woman pairing comprised a majority of the of the peer review publications at 47.5%. All results were statistically significant with a p-value <0.05. No significant correlation was found between region of institution or Altmetrics and gender of first or last authors [p>0.05]. Conclusion For the first time in oral health science, it was found that women show higher representation as first and last author positions in peer reviewed publications versus pre-prints.

Abstract
Procedures and models of computerized data analysis are becoming researchers' and practitioners' thinking partners by transforming the reasoning underlying biomedicine. Complexity theory, Network analysis and Artificial Intelligence are already approaching this discipline, intending to provide support for patient's diagnosis, prognosis and treatments. At the same time, due to the sparsity, noisiness and time-dependency of medical data, such procedures are raising many unprecedented problems related to the mismatch between the human mind's reasoning and the outputs of computational models. Thanks to these computational, non-anthropocentric models, a patient's clinical situation can be elucidated in the orthodontic discipline, and the growth outcome can be approximated. However, to have confidence in these procedures, orthodontists should be warned of the related benefits and risks. Here we want to present how these innovative approaches can derive better patients' characterization, also offering a different point of view about patient's classification, prognosis and treatment.

Abstract
OBJECTIVES To determine whether librarian or information specialist authorship is associated with better reproducibility of the search, at least three databases searched, and better reporting quality in dental systematic reviews (SRs). METHODS SRs from the top ten dental research journals (as determined by Journal Citation Reports and Scimago) were reviewed for search quality and reproducibility by independent reviewers using two Qualtrics survey instruments. Data was reviewed for all SRs based on reproducibility and librarian participation and further reviewed for search quality of reproducible searches. RESULTS Librarians were co-authors in only 2.5% of the 913 included SRs and librarians were mentioned or acknowledged in only 9% of included SRs. Librarian coauthors were associated with more reproducible searches, higher search quality, and at least three databases searched. Although the results indicate librarians are associated with improved SR quality, due to the small number of SRs that included a librarian, results were not statistically significant. CONCLUSION Despite guidance from organizations that produce SR guidelines recommending the inclusion of a librarian or information specialist on the review team, and despite evidence showing that librarians improve the reproducibility of searches and the reporting of methodology in SRs, librarians are not being included in SRs in the field of dental medicine. The authors of this review recommend the inclusion of a librarian on SR teams in dental medicine and other fields.

Abstract
OBJECTIVE All soft and solid surfaces exposed to the oral cavity are covered by an acquired pellicle. While the pellicle adsorbed on enamel is well researched, only limited data are available on the dentin pellicle. The purpose of the present review is to summarize studies considering the composition, structure and properties of the dentin pellicle and compare them with the current state of research on enamel pellicle. METHODS The literature search was conducted using Medline database and Google Scholar, including checking reference lists of journal articles by handsearching. Thereby, 19 studies were included in the present review. RESULTS AND CONCLUSION The dentin pellicle has a similar ultrastructure to the enamel pellicle, which is up to 1 μm thick depending on pellicle formation time and localization in the oral cavity. In contrast, due to the lack of studies on the dentin pellicle regarding its composition and properties, a comparison to the enamel pellicle is difficult. So far, only one study showed anti-abrasive properties and data on anti-erosive properties were controversial. Despite becoming more and more clinically relevant due to the increasing frequency of dentin exposure, the dentin pellicle is largely unexplored. For further investigations it is not only necessary to standardize dentin specimens, but also to assess fundamental research on dentin itself, as its complex morphology and composition may have a crucial influence on pellicle formation. Furthermore, a more detailed knowledge of the dentin pellicle may also reveal target sites for modification in favor of its protective properties.

Abstract
OBJECTIVES The number of studies employing artificial intelligence (AI), specifically machine and deep learning, is growing fast. The majority of studies suffer from limitations in planning, conduct and reporting, resulting in low robustness, reproducibility and applicability. We here present a consented checklist on planning, conducting and reporting of AI studies for authors, reviewers and readers in dental research. METHODS Lending from existing reviews, standards and other guidance documents, an initial draft of the checklist and an explanatory document were derived and discussed among the members of IADR's e-oral network and the ITU/WHO focus group "Artificial Intelligence for Health (AI4H)". The checklist was consented by 27 group members via an e-Delphi process. RESULTS Thirty-one items on planning, conducting and reporting of AI studies were agreed on. These involve items on the studies' wider goal, focus, design and specific aims, data sampling and reporting, sample estimation, reference test construction, model parameters, training and evaluation, uncertainty and explainability, performance metrics and data partitions. CONCLUSION Authors, reviewers and readers should consider this checklist when planning, conducting, reporting and evaluating studies on AI in dentistry. CLINICAL SIGNIFICANCE Current studies on AI in dentistry show considerable weaknesses, hampering their replication and application. This checklist may help to overcome this issue and advance AI research as well as facilitate a debate on standards in this fields.

Abstract
Crocodilians exhibit continuous tooth replacement (i.e., polyphyodonty) and have been identified as suitable models for tooth regeneration research due to the similarity in dental cavity and tooth anatomy between these creatures and humans. Various studies reporting in ovo bird embryo manipulation exist, but such reports for reptiles are virtually non-existent. Egg windowing enables direct access to oviparous vertebrate embryos and is therefore an important component of in ovo embryo manipulation experiments. The aim of the present study was to window Nile crocodile, Crocodylus niloticus eggs and assess the potential of direct manipulations, targeting the pharyngeal region where the maxilla and mandible originates. Crocodylus niloticus eggs were successfully windowed, and a limited number of individuals survived the entire gestation period. The 1st trimester of gestation was the most sensitive, and 96.78% of the mortalities occurred within this period. Our data indicate the suitable window for embryo manipulation targeting the mandibular arch and maxillary process, without a risk of damaging the chorioallantoic membrane (CAM) (which may be fatal), was between day six and eight after laying for embryos incubated at 31°C. This data will be of use for future embryo-based experiments related to jaw and tooth development in crocodiles as well as human tooth regeneration research.

Abstract
The increasing use of three-dimensional (3D) imaging techniques in dental medicine has boosted the development and use of artificial intelligence (AI) systems for various clinical problems. Cone beam computed tomography (CBCT) and intraoral/facial scans are potential sources of image data to develop 3D image-based AI systems for automated diagnosis, treatment planning, and prediction of treatment outcome. This review focuses on current developments and performance of AI for 3D imaging in dentomaxillofacial radiology (DMFR) as well as intraoral and facial scanning. In DMFR, machine learning-based algorithms proposed in the literature focus on three main applications, including automated diagnosis of dental and maxillofacial diseases, localization of anatomical landmarks for orthodontic and orthognathic treatment planning, and general improvement of image quality. Automatic recognition of teeth and diagnosis of facial deformations using AI systems based on intraoral and facial scanning will very likely be a field of increased interest in the future. The review is aimed at providing dental practitioners and interested colleagues in healthcare with a comprehensive understanding of the current trend of AI developments in the field of 3D imaging in dental medicine.

Abstract
INTRODUCTION Undergraduate research projects have never been evaluated despite six decades of dental training in Nigeria. This study evaluated dental graduates' perceptions of the research project from 2013 to 2017. METHODS A cohort of 93 graduates from a Nigerian University was investigated through the use of self-administered questionnaires on a Google form platform. Analysis was done using descriptive and analytical statistics on SPSS version 16. Statistical significant level was set at P < .05. RESULTS The cohort showed a very good understanding of research project objectives during their undergraduate training with more male and older students independently choosing their research topics (P > .05). Students' research topics were changed by supervisors in about one-quarter and one-tenth of the male and female students, respectively. About one-third of the students met set deadlines with no significant differences amongst gender and age groups (P > .05). However, only two-thirds of the students submitted their projects before the deadline due to other contending academic works. More males and older age group sought assistance from other academic staff for information on their projects. About one-half of the students reportedly acquired additional knowledge as a direct benefit from the project. Of all the variables associated with the research project, only the level of preparedness to undertake the project was highly statistically significant (P < .05) and this varied significantly amongst gender and age group (P < .05). CONCLUSION The students demonstrated a good understanding of research project. The perceived level of preparedness to undertake the project was low but significantly higher in male and older age groups.

Abstract
BACKGROUND Proposal writing before starting research study is the key component of the any research project and quality of the research depends upon how the proposal was designed and planned. Objectives of this study was to determine the frequency of most common errors in proposal writing by post graduate medical residents of College of physician and surgery of Pakistan (CPSP) at Peshawar. METHODS A cross sectional study was carried at Khyber College of Dentistry (KCD) Peshawar from August 2017 to May 2018. We conducted the reviewed of Form "S" of 43 proposals through convenience sampling. Each Form S consists of 34 questions. All the questions were dichotomous which were presented in the form of frequency and percentages. Data were analysed by SPSS-22. RESULTS Out of 43 proposal, the result shows that 53.5% (n=23) of the candidates have not explained the introduction in their own words while suitable statistical tests were not mentioned in more than half of the 67.4% (n=29) proposal. References were not written in Vancouver style 51.2% (n=22) as well as hypothesis was not applicable in 62.8% (n=27) of the studies. However only 39.5% (n=60.5) of the trainees phrased the hypothesis properly. CONCLUSIONS Majority of the candidates were unable to write the proposal according to the recommended guidelines. Application of the appropriate statistical measures was found as a challenge for the candidates. Similarly, objectives were not clearly defined in terms of SMART concept.

Abstract
This volume of Periodontology 2000 represents the 25th anniversary of the Journal, and uses the occasion to assess important advancements in periodontology over the past quarter-century as well as the hurdles that remain. Periodontitis is defined by pathologic loss of the periodontal ligament and alveolar bone. The disease involves complex dynamic interactions among active herpesviruses, specific bacterial pathogens and destructive immune responses. Periodontal diagnostics is currently based on clinical rather than etiologic criteria, and provides limited therapeutic guidance. Periodontal causative treatment consists of scaling, antiseptic rinses and occasionally systemic antibiotics, and surgical intervention has been de-emphasized, except perhaps for the most advanced types of periodontitis. Plastic surgical therapy includes soft-tissue grafting to cover exposed root surfaces and bone grafting to provide support for implants. Dental implants are used to replace severely diseased or missing teeth, but implant overuse is of concern. The utility of laser treatment for periodontitis remains unresolved. Host modulation and risk-factor modification therapies may benefit select patient groups. Patient self-care is a critical part of periodontal health care, and twice-weekly oral rinsing with 0.10-0.25% sodium hypochlorite constitutes a valuable adjunct to conventional anti-plaque and anti-gingivitis treatments. A link between periodontal herpesviruses and systemic diseases is a strong biological plausibility. In summary, research during the past 25 years has significantly changed our concepts of periodontitis pathobiology and has produced more-effective and less-costly therapeutic options.

Abstract
Advancements in research and technology are transforming our world. The dental profession is changing too, in the light of scientific discoveries that are advancing biological technology-from new biomaterials to unravelling the genetic make-up of the human being. As health professionals, we embrace a model of continuous quality improvement and lifelong learning. Our pedagogical approach to incorporating the plethora of scientific-technological advancements calls for us to shift our paradigm from emphasis on skill acquisition to knowledge application. The 2017 ADEE/ADEA workshop provided a forum to explore and discuss strategies to ensure faculty, students and, ultimately, patients are best positioned to exploit the opportunities that arise from integrating new technological advances and research outcomes. Participants discussed methods of incorporating the impact of new technologies and research findings into the education of our dental students. This report serves as a signpost of the way forward and how to promote incorporation of research and technology advances and lifelong learning into the dental education curriculum.

Abstract
The world's population is aging, and it has been estimated that by 2050, the number of people 65 years of age and older will reach 1.5 billion. The aging population will be affected by noncommunicable chronic diseases, including diabetes mellitus, cardiovascular disease and cognitive impairment. This important demographic shift includes a reduction in tooth loss/edentulism, particularly in older adults of the developed countries in North America, western Europe and north-east Asia. Therefore, in the future, dental providers will be required to care for an expanded number of older adults who have retained teeth and are medically complex. As the linkage of oral disease and systemic disease has focused on the relationship of periodontitis and noncommunicable chronic diseases, a broad review of 'geriatric periodontology' is both timely and important. This volume of Periodontology 2000 covers a range of subjects under this heading. Included are the demographics of an aging world; the effect of aging on stem cell function in the periodontium; the periodontal microbiota associated with aging; the host response in the periodontium of aging individuals; an analysis of the prevalence of periodontitis in the USA on a national, state-wide and community basis; differentiation of physiologic oral aging from disease; treatment of periodontal disease in older adults; implant therapy for older patients; oral disease and the frailty syndrome; the relationship of tooth loss to longevity and life expectancy; and the relationship of periodontal disease to noncommunicable chronic diseases. Although 'geriatric dentistry' is not a recognized specialty in dentistry, and 'geriatric periodontology' is a descriptive title, the subject of this volume of Periodontology 2000 is critical to the future of clinical dentistry, dental public health and dental research. Any comprehensive focus on older patients can only be accomplished with an emphasis on interprofessional education and practice. If embraced, this shift will allow the dental profession to be more closely aligned with the larger health-care environment, and can improve both oral health and health outcomes for patients seen in the dental office.

Abstract
BACKGROUND To quantify participation in dental research activities in Malaysia, and investigate its association with socio-demographic and professional characteristics, and perceptions of research and development (R&D) culture. MATERIALS AND METHODS Dental academics in Malaysian dental schools were invited to complete a questionnaire by email and post. The survey comprised questions on research activities in the past 12 months, socio-demographic and professional characteristics, and the R&D Culture Index. Principal components factor analysis was carried out to confirm the factor structure of the R&D Culture Index. Chi-square test was used to identify association of research activities with R&D culture, and socio-demographic and professional characteristics. Binary logistic regression was carried to identify predicators of research activities. RESULTS Of 256 potential participants contacted, 128 (50%) useable responses were returned. Three R&D Culture factors accounting for 57.4% of variance were extracted. More positive perception of R&D Support was associated with Malaysians (0.025) and those employed in Government schools (0.017). R&D Skills and Aptitude were associated with older respondents (0.050), PhD qualification (0.014) and more years in academia (0.014). R&D Intention was associated with any of the socio-demographic characteristics. Thirty (23.4%) respondents reported a peer-review research publication in the past 12 months, which was associated with having a PhD (OR 12.79, CI 1.28-127.96), after adjustment in regression analyses. DISCUSSION Postgraduate research training should be encouraged to promote participation in research activities. R&D culture did not appear to impact on research productivity. Other factors such as individual attitudinal interests should be studied.

Abstract
AIMS To quantify the practice patterns of Japanese dentists in the management of pain related to temporomandibular disorders (TMD) and to identify specific characteristics that are significantly associated with the decision to perform occlusal adjustment for TMD-related pain. METHODS A cross-sectional study was conducted consisting of a questionnaire survey of dentists affiliated with the Dental Practice-Based Research Network Japan (JDPBRN) (n = 148). Participants were asked how they diagnosed and treated TMD-related pain. Associations between dentist characteristics and the decision to perform occlusal adjustment were analyzed via multiple logistic regression. RESULTS A total of 113 clinicians responded to the questionnaire (76% response rate), and 81% of them (n = 89) had treated TMD during the previous year. Dentists treated an average of 1.9 ± 1.8 (mean ± SD) patients with TMD-related pain per month. Most JDPBRN dentists used similar diagnostic protocols, including questions and examinations. The most frequent treatments were splints or mouthguards (96.5%), medications (84.7%), and self-care (69.4%). Occlusal adjustment for TMD-related pain was performed by 58% of the participants. Multiple logistic regression analysis identified two factors significantly associated with the decision to perform occlusal adjustment: dentist lack of confidence in curing TMD-related acute pain (odds ratio [OR] 5.60; 95% confidence interval [CI] 1.260 to 24.861) and proportion of patients with severe TMD-related pain (OR 0.95; 95% CI 0.909 to 0.999). CONCLUSION The most common treatments for TMD-related pain were reversible treatments; however, over half of the dentists performed occlusal adjustment for TMD-related pain. The results of this study suggest that an evidence-practice gap exists for occlusal adjustment for TMD-related pain.
