Dental research in Iran: a bibliometric analysis of electronically available literature

Purpose : To carry out a bibliometric analysis of all electronically available dental literature in Iran from 1983 to 2006, in order to study availability and examine trends. Materials and Methods : Accessing all electronically available Iranian dental articles published in domestic journals, and comparing the results with Iranian dental articles published in Pubmed. The following data were collected from each article: name of journal, year of publication, number of authors, gender of corresponding author, academic levels of authors, main language of article, language of abstract, study environment, population studied, field of dentistry, type of article, design strategy, design of study, and analysis design. Results : In terms of publications in domestic journals, a total of 1,994 dental articles were electronically available, published in six different dental journals in Iran. Majority of articles, 84.5%, were original studies. In terms of design strategy, 49.7% of studies were cross‐sectional, 35.5% were prospective, and 14.8% were retrospective studies. The main language of 99.3% of articles was Farsi, and 0.7% was English. Majority of articles, 38.7%, were written by two authors. Gender of corresponding author in 66.7% of articles was male, and in 33.3% of articles was female. There was an increasing trend in percentage of original studies, clinical trials and female corresponding authors. In terms of publications in Pubmed, a total of 75 dental articles from Iran were electronically available. Significant differences were revealed in terms of number of authors, study types and design strategies when compared to publications in domestic journals. Conclusion : A number of encouraging trends were identified, which is a reflection of improvements in quality of domestic electronic dental literature. However, as the majority of articles are written in Farsi, availability of research evidence to the international community is limited. Overall, results of this study indicate the need for future bibliometric analyses which can be used to construct a comprehensive database that will assist in evidence‐based clinical decision making.     

Influence of prosthetic and implant therapy on satisfaction and quality of life: a systematic literature review. Part 1--Characteristics of the studies

PURPOSE: This study systematically searched the dental literature to identify and classify articles on the influence of prosthodontic and dental implant treatment on patient satisfaction and oral health-related quality of life according to their level of evidence. MATERIALS AND METHODS: A literature search was carried out for articles published between 1960 and February 2003 using an electronic key word search complemented by hand searching. The retrieved articles were subjected to inclusion and exclusion criteria. Only experimental studies were included; articles that did not focus on the effect of therapy on the patient were excluded from further processing. The levels of evidence of the articles were classified following the guidelines of the US Agency for Health Care Policy and Research. RESULTS: A total of 207 publications were identified, of which 114 reports investigating 24,863 patients met the inclusion criteria. Data from the studies were analyzed using SPSS 9.0. Two thirds of the publications showed a low evidence level of III; most were conducted in patients who were edentulous or restored with complete dentures (59% of all studies). Mostly, nonstandardized, custom-made questionnaires (80%) were used. On average, 9 (SD 4.2) outcome variables were used within each trial, but clinical criteria were more often used than psychosocial criteria. The most frequently used questions concerned "chewing function" (86%), esthetics (77%), speech (68%), and general satisfaction (67%). Validated instruments, such as the Oral Health Impact Profile, were increasingly used in recent studies, which were also methodically more sufficient. CONCLUSION: Few studies with high levels of evidence were found. Research in this field is still in a phase of development.     

Osseointegration and clinical success of zirconia dental implants: a systematic review

PURPOSE: Various ceramic implant systems made of yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) have become commercially available in recent years. A systematic search of the literature was performed to assess the clinical success of dental Y-TZP implants and whether the osseointegration of Y-TZP is comparable to that of titanium, the standard implant material. MATERIALS AND METHODS: The internet database MEDPILOT was searched cumulatively for the keywords zircon* and dent* and implant as well as for zircon* and osseointegration. The last search was conducted on January 31st, 2007. Subsequently, the reference lists of the relevant publications were searched. Furthermore, a letter was sent to the 5 identified manufacturers of zirconia dental implants to ask for peer-reviewed publications. RESULTS: Ninety-six articles were found by the search strategy. No controlled clinical studies in humans regarding clinical outcomes or osseointegration could be identified. Clinical data were restricted to case studies and case series. Only 7 animal studies fulfilled the inclusion criteria. Osseointegration was evaluated at 4 weeks to 24 months after placement in different animal models and sites and under different loading conditions. The mean bone-implant contact percentage was above 60% in almost all experimental groups. In studies that used titanium implants as a control, Y-TZP implants were comparable to or even better than titanium implants. Surface modifications may further improve initial bone healing and resistance to removal torque. CONCLUSIONS: Y-TZP implants may have the potential to become an alternative to titanium implants but cannot currently be recommended for routine clinical use, as no long-term clinical data are available.     

The trends of dental biomaterials research and future directions: A mapping review

ObjectiveThis literature research aimed to compare, contrast and quantify the innovations in the most commonly used dental biomaterials.MethodologyOriginal research articles based on experimental dental biomaterials published between 2007 and 2019 were retrieved and reviewed. A search of electronic databases, PubMed, Scopus, and Web of Science indexed dental/biomaterials journals, has been conducted. The inclusion criteria in this research were: synthesis of experimental dental materials, whereas commercial dental materials, review articles, and clinical trials (case reports) were excluded.ResultsIt was found that the amount of publications related to dental subgingival implants, computer-aided modeling ceramics, aesthetic restorative materials, adhesives cements, ceramics, bioceramics, endodontic materials, bioactive scaffolds, stem cells, and guided-tissue membranes had increased significantly from 2007. At the same time, the number of publications related to dental cements, silver amalgam, and dental alloys has decreased. For characterization of dental materials it was noted that mechanical properties were tested mostly for restorative materials. On the other hand, biological properties were most assessed for dental subgingival implants and endodontic materials, however, physical properties predominantly for bioceramics.ConclusionIt is concluded that to meet clinical demands there was more focus on restorative materials that provided better aesthetics, including resin composites, adhesive resin composites (luting cements), zirconia, and other ceramics. The boost in laboratory and animal research related to bioceramics was attributed to their regenerative potential. This current literature study will help growing researchers to consider and judge the direction to which research might be guided in order to plan prospective research projects.

Immediate implant placement in endodontically infected sites: an alternative treatment for compromised teeth

In certain clinical conditions when endodontic treatment is either impractical or unlikely to improve the previous results, tooth extraction and replacement with a dental implant becomes a viable alternative. Although the presence of active infection has long been considered a major contraindication to the insertion of implants immediately following tooth extraction, several articles assessing this treatment modality reported excellent and promising results. The aim of this literature review is to evaluate and discuss the clinical outcome of implants placed immediately following extraction in endodontically infected sockets. A Medline and EMBASE search was performed to identify articles published from 1966 to 2010 using the keywords "dental implants", "immediate implant", "extraction socket", "infected teeth", "infected site", "infected socket". No restrictions were placed regarding the study design. Only clinical articles with at least 6 months of follow-up were included. The available relevant literature concerning this topic was limited, and based on relatively low level of evidence study designs with limited follow-up periods. However, the data analysis of the selected articles showed that an immediate implant insertion in endodontically infected sites following tooth extraction and careful debridement of the socket, could be a predictable viable technique. Additional large scaled, well-designed studies are required in order to further assess the clinical applications of this treatment alternative.     

Association between Orthopedic and Dental Findings: What Level of Evidence is Available?

OBJECTIVE: The aim of this systematic review was to provide comprehensive access to and an analysis of the specialist literature published through December 2005 describing a correlation between orthopedic (leg-length inequality, pelvis obliquity, column diseases and head posture) and dental findings (occlusion, mandibular position, temporomandibular joints, masticatory muscles). METHOD: Four medical and dental internet sources (PubMed; Medpilot.de; databases of the Deutsche Arzte-Verlag and Quintessenz-Verlag) were screened for relevant articles using carefully selected retrieval strategies and keywords. Bibliographies of relevant articles were examined for further pertinent publications. All relevant articles were tabulated according to their year of publication, the subject area discussed, and the levels of scientific evidence. RESULTS: Our electronic inquiry yielded 359 relevant articles (electronic search: 195, search in bibliographies: 164), 355 of which could be analyzed. A correlation between dental findings and spinal column diseases was described in 266 articles, head posture in 216, pelvis obliquity in 53, and leg-length inequality in 35 papers. In 131 publications, conclusions were drawn from dental to orthopedic findings, whereas they were drawn from orthopedic to dental findings in 171 articles. The number of relevant articles rose significantly, particularly since the 1980's. Classification in levels of evidence reveals three publications (0.8%) with level II (randomized controlled trials), 63 (17.7%) with level III (experimental studies with no randomization, cohort studies, or case-control studies), 178 (50.1%) with level IV (non-experimental studies, such as cross-sectional trials, case series, case reports), and 111 (31.3%) with level V (narrative review or expert opinion without explicit critical appraisal). CONCLUSIONS: 1) While there is great interest in possible correlations between orthopedic and dental findings in the specialist literature, most publications fail to provide the hard facts and solid evidence characteristic of high-quality research. 2) This literature analysis attests to the importance of searching electronic databases while making the inherent weaknesses of such searches obvious. Manual literature searches remain essential.     

The role of pathophysiological explanations in clinical case representations of dental students and experts

Introduction:  Teaching of biomedical knowledge lays the foundations for the understanding and treatment of diseases. However, the representation of pathophysiological explanations in the management of clinical cases differs for various levels of medical expertise and different theories have been proposed to explain this phenomenon. The present study investigated for the first time how biomedical knowledge is used in clinical reasoning in dental medicine.
Materials and methods:  In an experimental study 20 experts in the field of Periodontology and 61 students of different levels of training produced written pathophysiological explanations after having studied three different clinical cases. By comparing the written protocols to a visualised expert-made 'canonical' explanation the concepts used in the pathophysiological explanation were counted and classified as well as the links between concepts.
Results:  The statistical analysis by MANOVA showed significant differences between third- and fourth-year students, students of intermediate expertise level (fifth-year) and experts for various parameters qualifying concepts or links of the written pathophysiological explanations. The participants of intermediate expertise level produced a high rate of concepts and links; however, characteristic findings for knowledge encapsulation in the different levels of expertise were not evident. The analysis showed that the design of the clinical cases and of the canonical explanations significantly influenced the outcomes.
Conclusion:  The present study demonstrated the pathophysiological representations of clinical cases in dental students and experts to be different from other medical disciplines. It could be assumed that this observation is based on different contents for teaching of practical skills and diagnostic procedures in dental compared with medical education.     

Influence of implant and conventional prostheses on satisfaction and quality of life: A literature review. Part 2: Qualitative analysis and evaluation of the studies

PURPOSE: To review the influence of prosthodontic and dental implant treatment on patient satisfaction and oral health-related quality of life (OHQOL) based on a systematic search of the literature. MATERIALS AND METHODS: A systematic literature search was carried out for articles published between 1960 and February 2003. Details of the search process and results were reported in Part 1 of the study (Int J Prosthodont2004;17:83-93). The included studies were categorized and evaluated according to their level of evidence, following the guidelines of the Agency for Health Care Policy and Research. The characteristics and content of the studies were analyzed and tabulated. RESULTS: Among the 114 included studies, there were 76 publications reaching evidence level III. The results showed that the effects of compromised oral health are not limited to traditional clinical aspects, but can considerably affect patients in various activities of daily life. Twenty-four of the 38 investigations with evidence levels I and II dealt with implant stabilization of complete mandibular prostheses, comparing implant prostheses to conventional complete dentures. Fully edentulous patients experience negative impacts on OHQOL from their condition. They benefit significantly from the use of dental implants to support mandibular prostheses. However, support by more than 2 implants does not appear to further significantly increase patient satisfaction and OHQOL. CONCLUSIONS: To date, research in the field of patient-based outcomes has concentrated on dental implant treatment for the edentulous patient. Other prosthetic treatments such as single crowns, fixed and removable partial dentures, or further treatment concepts (eg, the shortened dental arch concept) are not well represented. The use of patient-centered outcome measures can help to find an individual, patient-oriented prosthetic solution.     

Outcomes of Dental Implants in Osteoporotic Patients. A Literature Review

Purpose: This article reviews available data on the outcome of dental implants in osteoporotic patients.
Materials and Methods: A search was performed in PubMed and completed in July 2007. The keywords "dental AND implants AND osteoporosis,""dental AND implants AND age,""dental AND implants AND gender," and "dental AND implants AND bone AND quality," with no limitations for language or year of publication, resulted in 82, 598, 94, and 541 articles, respectively. After abstract scanning (in case of doubt the article was read), 39 nonreview articles studying dental implant outcomes in osteoporotic/osteopenic subjects remained for our review. The bibliographies of the 39 articles were also inspected, but no additional studies were identified.
Results: Thirteen of 16 animal studies found lower osseointegration rates in osteoporotic/osteopenic bone than in normal bone. Six in nine clinical reports mention success. Eight of 12 studies in humans support the applicability of dental implants in osteoporotic patients.
Conclusions: There are no data to contraindicate the use of dental implants in osteoporotic patients; however, a proper adjustment of the surgical technique and a longer healing period may be considered in order to achieve osseointegration. Data on the use of biphosphonates in osteoporotic patients and implant outcomes are very limited, and no conclusions can be drawn. In addition, large prospective studies investigating the long-term success of dental implants in osteoporotic individuals are required.
