RESUMO

OBJECTIVE: Bibliometric analysis and citation counts help to acknowledge influence of publications. The aim of this study was to conduct bibliometric and citation analysis of top-cited articles, from low- and lower-middle income countries, on use and application of digital technology in dentistry. METHODOLOGY: A search strategy based on "Digital Dentistry", "Low Income Countries", and "Lower-Middle Income Countries" was used in October 2023 using Scopus database to retrieve articles relevant to digital dentistry, with citation count of 10 or more. From 44 included articles, bibliometric information was analyzed on SPSS version 23. Network analysis based on co-citations, keywords, and number of citations was conducted on VOS software (version 1.6.20). RESULTS: Most relevant articles were published in 2021 (n = 8), with 52.3% original articles, out of which 40.9% were in vitro studies. India had the highest number of articles (n = 24), with most publications in The Journal of Indian Prosthodontic Society (n = 4), and in the domain of General Dentistry (n = 15, 34.1%). Co-authorship network analysis was not significant, but country-wise co-authorship analysis revealed India with the greatest link strength (4.0). Highest occurring keyword was 3D printing (link strength 5.0), and the citation analysis revealed Journal of Prosthetic Dentistry with the most number of published documents (3), having a citation count of 275. Bibliographic coupling for sources revealed Journal of Indian Prosthodontic Society to have the highest link strength of 15.33. CONCLUSION: This analysis uncovers interesting bibliometric and citation based information including key thematic trends, emphasizing crucial role of technologies like 3D printing, CAD/CAM, and CBCT in digital dentistry. The study underscores the imperative for increased original research efforts in low- and lower middle-income countries.

RESUMO

Artificial intelligence (AI) has been integrated into dentistry for improvement of current dental practice. While many studies have explored the utilization of AI in various fields, the potential of AI in dentistry, particularly in low-middle income countries (LMICs) remains understudied. This scoping review aimed to study the existing literature on the applications of artificial intelligence in dentistry in low-middle income countries. A comprehensive search strategy was applied utilizing three major databases: PubMed, Scopus, and EBSCO Dentistry & Oral Sciences Source. The search strategy included keywords related to AI, Dentistry, and LMICs. The initial search yielded a total of 1587, out of which 25 articles were included in this review. Our findings demonstrated that limited studies have been carried out in LMICs in terms of AI and dentistry. Most of the studies were related to Orthodontics. In addition gaps in literature were noted such as cost utility and patient experience were not mentioned in the included studies.

RESUMO

OBJECTIVES: The objective of this study was to explore current trends in undergraduate fixed prosthodontics teaching at undergraduate dental level education. METHODS: This cross-sectional descriptive study included close-ended questions to inquire about the teaching practices of fixed prosthodontics at Bachelor of Dental Surgery level education. Electronic copies of the survey forms were sent to the heads or directors of department of prosthodontics responsible for undergraduate dental students teaching and learning in various institutes of Sindh by the help of Google forms in December 2020. The form included questions on sociodemographic details and questions inquiring the theoretical and clinical teaching practices in undergraduate fixed prosthodontics course. Data was entered and analyzed using SPSS 25. Frequency distribution and percentages of categorical variables were recorded. RESULTS: Out of total 18 dental institutes of Sindh, 15 returned the completely filled form, giving a response rate of 83.3%. Seven (46.7%) schools teach various fixed prosthesis in the preclinical years to their students. All 15 colleges carry out didactic teaching and provide exposure by live clinical demonstrations for various fixed prosthesis. Faculty of 12 (80%) dental colleges where fixed prostheses are being constructed in the dental outpatient department mentioned that their students observe or assist the clinical procedures during their clinical rotation; but none of the students fabricate any type of fixed prosthesis in the clinical setting during their undergraduate years. CONCLUSION: Didactic teaching and live clinical demonstrations of fixed prosthodontics is being carried out in all dental colleges of Sindh. Almost half of the dental schools teach crown preparation on phantom teeth during their preclinical course. Contrary to this, none of the students fabricate any type of fixed prosthesis in the clinical setting during their undergraduate years. As these procedures are not included in the current undergraduate curriculum, recommendations should be forwarded to governing educational body of the country to include cases of fixed prosthesis in their skill set prior to their graduation.

RESUMO

OBJECTIVE: The aim of this study was to determine the perception of faculty of undergraduate medical and dental programmes in various private and public sector institutes regarding their Readiness, Attitude and Institutional support for developing high-quality one-best MCQs. METHODS: A validated questionnaire was designed for recording demographic data and responses related to Readiness, Attitude and Institutional support based on 5-point Likert scale and multiple options. Scores for items on Likert scale were categorised (Readiness: poor 0-12, good 13-24, Attitude: negative 0-12, positive 13-24, Institutional support: no support 0-12, highly supportive 13-24). The individual and overall scores related to Readiness, Attitude and Institutional support were compared to demographic characteristics using Independent samples and Paired samples t-test as appropriate. Data was analysed using SPSS version 25.0. P-value of <0.05 (two-sided) was considered significant. RESULTS: With a response rate of 87.5%, the mean scores for Institutional support were higher (14.45 ± 4.73) compared to those for Readiness (13.39 ± 4.51) and Attitude (12.54 ± 4.59). Responses to multiple choice items revealed that faculty considered MCQ writing workshops to be effective while facing most difficulty in formulating scenario and homogenous options. Most faculty reported no commitment issues but desired on-job protected time for item development. No significant association was found between the scores and age group, gender, qualification, institute type, department and designation of participants. CONCLUSION: Overall, the faculty were found to be motivated and committed to developing high-quality one-best MCQs. With continued institutional support, faculty can be expected to further engage in writing such items.

RESUMO

BACKGROUND: Bibliometric analysis of a particular specialty published in single journal allows the identification of publication trends, areas of focus and potential domains for future research that could be publishable within the scope of that journal. This study aimed to analyse the characteristics of dental literature published in JCPSP in order to determine the trend of publication of dentistry-related papers in this journal. METHODS: An electronic and hand search was conducted of all JCPSP issues from 1991 till June 2018. The selected articles were analysed for year of publication, field of study, type of article, the names of first author, their gender and affiliation (institute, country), number of authors in each publication and citation count. Data was statistically analysed using SPSS version 20.0. RESULTS: Out of approximately 5,400 published articles, 253 were included for analysis. Articles related to Oral and Maxillofacial surgery were in majority (n=54), followed by Operative Dentistry and Endodontics (n=38). Most (n=103) were original research articles. Pakistani authors contributed the majority of articles (n=184). The greatest number of dental articles were published in the year 2014 and 2017 (n=30). The institutions with the highest number of dental papers were Aga Khan University, Karachi and NIMS Dental College, Jaipur, India. The majority of articles were by Manas Bajpai as first author (n=22 articles). The highest citation count was found to be 55. CONCLUSIONS: Overall, the proportion of dentistry related articles published in JCPSP is low (4.6%). Researchers working in dental specialties where few publications were observed could be invited to submit relevant publications to JCPSP to broaden the scope of the journal. Foreign authorship should be encouraged to further elevate the standing of this journal. A separate journal for dental research in light of the continually increasing number of dental specialists and researchers is the need of the hour.

RESUMO

OBJECTIVE: To identify factors that influence the choice of specialty of dentistry postgraduate residents in an urban setting. METHODS: The cross-sectional analytical study was conducted from April to May 2020 at health centres approved for the Fellowship of the College of Physicians and Surgeons training in Karachi, and comprised dental postgraduate residents. Data was collected using a questionnaire distributed using Google Forms. Residents were asked to rate factors that influenced their decision to join their clinical specialty on a 3-point Likert scale. Items were based on the basis of anticipated clinical experiences, specialty-specific factors, personal preferences, and possible constraints. Data was analysed using SPSS 23. RESULTS: Of the 51 subjects, 39(76.5%) were females and 12(23.5%) were males. The overall mean age was 27.7±2.17 years. Besides, 27(52.9%) subjects were from public-sector centres and 24(47.1%) from private-sector centres. Of all the residents, 44(86.3%) chose their specialty because of inclination to treat complex cases, while 43(84.3%) were interested because of the broad range of cases, and 39(76.5%) made their choice because of the reputation of the respective supervisors and institutions. Also, 43(84.3%) residents did not consider the expiry of their fellowship part one exam deadline, or unavailability of a training slot as a specific reason to select a specialty. Compared to males, significantly more females opted for a specialty if it eventually provided career opportunity as faculty (p<0.05). CONCLUSIONS: Factors that greatly influenced the residents' choice for postgraduate training specialty were related to anticipated clinical experiences.

RESUMO

BACKGROUND: The perceptions and trends of magnification use in dentistry need to be determined since magnification significantly enhances clinical practice. OBJECTIVE: To assess perception and practices of Operative and Endodontic specialists currently working in Pakistan, regarding use of magnification. METHODS: A structured questionnaire administered for this analytical cross-sectional study recorded demographics, trends of magnification devices used in practice and their perceived advantages and disadvantages by the specialists with close-ended questions and three-point Likert scale. RESULTS: Out of 91 forms, 77 responses were received (response rate of 84%). Most participants had 1-4 years of practical experience, were employed at both faculty and clinical positions, were more interested in operative/restorative procedures and used TLL (through the lens loupes) at low magnification. Use of magnification devices was learnt mostly during post-graduate training and was used daily or weekly for complicated cases. Noteworthy perceptions included improved treatment quality and standard of care. However, they were also perceived as irritating, increasing treatment time, with adverse effect on eyesight with prolonged use. No statistically significant correlation was found between the variables recorded (p > 0.05). CONCLUSIONS: Most specialists used magnification devices in some form and were abreast with their advantages. Proper training and continued dental education courses can help dispel any observed misapprehensions.

RESUMO

OBJECTIVES: Blended learning (BL) combines conventional face to face (F2F) sessions with online educational resources. This method includes the advantages of online course delivery without the omission of conventional F2F interaction. The purpose of the present study was to evaluate students' satisfaction and educational outcomes in a BL course compared to traditionally administered dental anatomy course. METHODS: A prospective non-randomized study was conducted to compare the outcomes and perception of BL for teaching dental anatomy to dental students. First year dental anatomy students (n = 98) were included (48 in the conventional F2F learning and 50 in the BL group). Multiple choice questions were used to assess the achievement of learning outcomes and the Dundee Ready Education Environment Measure (DREEM) to determine the educational environment during the course. RESULTS: There was no significant difference in the pre-test scores of both groups; however the mean post-test score for the BL group (31.5 ± 4.5) was significantly higher than the F2F group (27.2 ± 4.9). The post-test scores were comparable across both genders in the BL group while females secured significantly higher scores than males in the F2F group. The DREEM scores were also significantly higher in the BL group (147.3 ± 15.5) than the F2F group (134.5 ± 15.1) (p < 0.002). A similar pattern was observed in DREEM subscales. CONCLUSIONS: The BL course is associated with improved students' satisfaction and learner achievement compared to a conventionally administered dental anatomy course. In addition, BL enhanced students' accessibility, self-assessment, and higher level of engagement compared to F2F delivery of the course.

RESUMO

OBJECTIVES: The aim of this study was to evaluate the patient's knowledge, attitude, and practice of cross-infection control in dentistry during coronavirus diseases 2019 (COVID-19). MATERIALS AND METHODS: This cross-sectional observational study was conducted at Altamash Institute of Dental Medicine, Karachi from June 2020 to August 2020. A total of 775 patients participated to fill questionnaire. After scrutiny, 25 questionnaire forms were excluded due to incomplete information. Questionnaire was divided in to four sections. First section obtained patients sociodemographic information, while knowledge of patients regarding cross-infection control during COVID-19 pandemic was evaluated in second section. Similarly, the purpose of third section was to assess attitude and fourth section was designed to evaluate practice. Likert's 3-point scale was used for registration of participant's response. The reliability of questionnaire was assessed through Crohnbach's α (α = 0.74). Statistical analysis was performed after entering data in to SPSS version 25. Independent t-test was used to evaluate the difference in patients' knowledge, attitude, and practice. A p-value ≤ 0.05 was considered as statistically significant. RESULTS: Majority of the participants agreed that COVID-19 is a highly contagious disease (631, 97%) and daily screening of staff, dental assistants, dentists, and patients is necessary (568, 75.7%) along with proper sterilization of instruments and disinfection of dental operatory (650, 86.66%). A large number of participant also agreed that proper disposal of waste is utmost important for cross-infection control (601, 80.24%) and patient's waiting area should also be marked with social distancing sign (620, 82.66%). However, when asked about the common route of COVID-19 transmission in dentistry, 341 (45.5%) participants disagreed that it is not through aerosol (water droplets) generated during dental procedures. CONCLUSIONS: Dental health professionals should take additional measures to educate dental patients on mechanism of potential spread of COVID-19 through the aerosols and droplets generated during dental procedures. They should also encourage the dental patients to be vigilant and question the cross-infection control measures practiced by the dentist to whom they go for dental treatment, and to decrease their chances of acquiring an infection during their visit to the dental office.

RESUMO

An outbreak of novel coronavirus disease (COVID-19) in China has influenced every aspect of life. Healthcare professionals, especially dentists, are exposed to a higher risk of getting infected due to close contact with infected patients. The current study was conducted to assess anxiety and fear of getting infected among dentists while working during the current novel coronavirus diseases (COVID-19) outbreak. In addition, dentists' knowledge about various practice modifications to combat COVID-19 has been evaluated. A cross-sectional study was conducted using an online survey from 10th to 17th March 2020. The well-constructed questionnaire was designed and registered at online website (Kwiksurveys) and validated. A total of 669 participants from 30 different countries across the world responded. After scrutiny, completed questionnaires (n = 650) were included in the study. Statistical analysis was performed using SPSS version 25. Chi-Square and Spearman correlation tests were applied to control confounders and assess the relation of dentists' response with respect to gender and educational level. More than two-thirds of the general dental practitioners (78%) from 30 countries questioned were anxious and scared by the devastating effects of COVID-19. A large number of dentists (90%) were aware of recent changes in the treatment protocols. However, execution of amended treatment protocol was recorded as 61%. The majority of the dentists (76%) were working in the hospital setting out of which 74% were from private, and 20% were from government setups. Individually we received a large number of responses from Pakistan and Saudi Arabia, but collectively more than 50% of the responses were from other parts of the world. Despite having a high standard of knowledge and practice, dental practitioners around the globe are in a state of anxiety and fear while working in their respective fields due to the COVID-19 pandemic impact on humanity. A number of dental practices have either modified their services according to the recommended guidelines to emergency treatment only or closed down practices for an uncertain period.

RESUMO

Endodontic treatment of maxillary incisors may be considered straight forward. However, in some instances, they may exhibit aberrant morphology. One of these rare variations in tooth morphology is dens invaginatus. To improve the endodontic prognosis of such teeth, a detailed evaluation of the tooth under treatment is important, which requires comprehensive clinical and radiographic examinations, including periapical radiography and cone-beam computed tomography (CBCT), which is highly recommended whenever atypical root canal morphology is suspected on a periapical radiograph. The current case report discusses the diagnosis of type IV dens invaginatus in a maxillary lateral incisor using CBCT.

RESUMO

The number of citations an article receives is an important indicator to quantify its influence in its field. The aim of this study was to identify and analyze the characteristics of the 50 top-cited articles addressing dental education published in two journals dedicated to dental education (European Journal of Dental Education and Journal of Dental Education). The Web of Science database was searched to retrieve the 50 most-cited articles from the two journals in December 2018. The top-cited articles were analyzed for journal of publication, number of citations, institution and country of origin, year of publication, study type, keywords, theme and subtheme, and international collaborations. The results showed the 50 top-cited articles were cited between 24 and 146 times each. The majority of these top-cited articles (n=34) were published in the Journal of Dental Education Half (n=25) of the articles were by authors in the U.S. The most common study types were surveys (n=26) and reviews (n=10). The main themes of these top-cited articles were curriculum and learner characteristics. This bibliometric analysis can serve as a reference for recognizing studies with the most impact in the scholarship of dental education.

RESUMO

INTRODUCTION: Bibliometric analysis is a method for quantifying the research productivity, author performance, and manuscript impact. The citation count received by a scientific article is one of the indicators of its impact within a field. The purpose of this study was to identify the 100 top-cited articles published in regenerative endodontics and to analyze their main characteristics. METHODS: Thomson Reuters Web of Science was searched to retrieve the 100 most-cited articles in "regenerative endodontics" published from January 1991 to February 2018 in the category of "Dentistry, Oral Surgery and Medicine." Among the included top-cited articles, the following parameters were recorded and analyzed: journal name, authors, institution, country, publication title and year, number of citations and average citations, type of study, collaborations, and key words. The data were analyzed using SPSS version 19.0 (IBM Corp, Armonk, NY) and VOS viewer software (version 1.6.7; Leiden University Center for Science and Technology Studies, Leiden, Netherlands). RESULTS: Among the 100 top cited articles, the highest number of citations that an article received was 309. The top cited articles appeared in 14 different journals, and the Journal of Endodontics published the greatest number of these articles (66%). The majority of articles were published in the year 2014 (n = 17). The majority of articles originated from the United States (n = 51) with the most contribution from The University of Texas Health Science Center, San Antonio, TX. The most frequent first authors were Torabinejad (n = 4), Nosrat (n = 3), and Thibodeau (n = 3). In vitro studies were the most common study design (n = 29) followed by reviews (n = 21). "Regenerative endodontics" was the most frequently used key word. CONCLUSIONS: This bibliometric analysis reveals the progress and trend of research in the field of regenerative endodontics. The in vitro articles published in the field of regenerative endodontics had the highest number of citations and average citation rates.

RESUMO

BACKGROUND/AIMS: A wide variety of materials has been researched for their use as potential storage media for avulsed teeth, but it is essential to recognize the medium most recommended for improvement of the prognosis of avulsed teeth. The aim of this systematic review was to identify the most recommended medium to store and transport avulsed teeth based on the survival of periodontal ligament (PDL) cells as determined by in vitro studies. METHODS: Only laboratory-based experimental studies on PDL cells found on adult permanent teeth were included. Data were collected using PubMed, CINAHL plus (EBSCO host), and the Cochrane Library, along with Google Scholar and a hand search. The key terms employed were permutations of [avulsed permanent teeth* OR dental avulsion* OR knocked out teeth*] AND [storage media* OR transport media* OR biological transport* OR PDL cell viability* OR PDL cell survival*]. A customized data extraction pro forma was used to extract the data and to evaluate the quality and risk of bias. RESULTS: The initial search yielded 978 articles, but only 67 were selected. Milk was the most recommended individual medium followed by Hank's balanced salt solution. Among natural products other than milk, propolis and coconut water were most frequently recommended. Recommendations were based on maintenance of PDL cell viability followed by ease of availability, low cost, and long shelf life. CONCLUSIONS: Natural products are more effective in maintaining the PDL cell viability compared to synthetic products. Some storage media recommendations were also based upon practical aspects. Although natural products other than milk have more recommendations as a group, milk is the most recommended storage medium individually, based not only on PDL cell viability, but also practical considerations.

RESUMO

PURPOSE: The aim of this systematic review was to assess the gingival retraction methods in terms of the amount of gingival retraction achieved and changes observed in various clinical parameters: gingival index (GI), plaque index (PI), probing depth (PD), and attachment loss (AL). METHODS: Data sources included three major databases, PubMed, CINAHL plus (Ebsco), and Cochrane, along with hand search. Search was made using the key terms in different permutations of gingival retraction* AND displacement method* OR technique* OR agents OR material* OR medicament*. RESULTS: The initial search results yielded 145 articles which were narrowed down to 10 articles using a strict eligibility criteria of including clinical trials or experimental studies on gingival retraction methods with the amount of tooth structure gained and assessment of clinical parameters as the outcomes conducted on human permanent teeth only. Gingival retraction was measured in 6/10 studies whereas the clinical parameters were assessed in 5/10 studies. CONCLUSIONS: The total number of teeth assessed in the 10 included studies was 400. The most common method used for gingival retraction was chemomechanical. The results were heterogeneous with regards to the outcome variables. No method seemed to be significantly superior to the other in terms of gingival retraction achieved. Clinical parameters were not significantly affected by the gingival retraction method.

RESUMO

OBJECTIVE: To compare mean micro-leakage around 3 types of temporary restorative materials in-vitro, when placed adjacent to permanent restorations (amalgam) in complex endodontic access cavities. STUDY DESIGN: Randomized controlled trial. PLACE AND DURATION OF STUDY: Dental Clinics, Dental Laboratory and Research Laboratory at The Aga Khan University Hospital, Karachi, from January to June 2014. METHODOLOGY: After random allocation of 60 teeth into 3 experimental groups, each group had conventional class II cavities prepared and amalgam placed. After 14 days, endodontic access cavities were made in these teeth, followed by placement of Cavit, IRM and CLIP(depth of 4 mm each). After thermo-cycling and immersion in 0.5% methylene blue dye, the teeth were sectioned mesio-distally and observed under stereoscopic microscope (magnification x4) along 2 interfaces 'a' and 'b' (tooth-temporary restoration and temporary restoration-primary restoration), respectively. Depth of dye penetration was measured in millimeters. RESULTS: IRM was leakiest at interface 'a', cavit had highest dye penetration at interface 'b', while CLIP exhibited least micro-leakage at 'a' and 'b'. The mean dye penetration for Cavit was 0.80 ± 0.23 mm at 'a', and 2.24 ± 0.48 mm at 'b'. For IRM, it was 1.82 ± 0.09 mm at 'a', and 0.44 ± 0.13 mm at 'b'. For CLIP, the mean dye penetration was 0.43 ± 0.05 mm at 'a', and 0.32 ± 0.12 mm at 'b'. The difference in dye penetration observed between the 3 groups at both interfaces was statistically significant. CONCLUSION: In a complex access cavity made adjacent to a pre-existing amalgam restoration, CLIP exhibits the least micro-leakage, followed by IRM and Cavit.

Invasive cervical resorption is a condition that affects the root surface area below the epithelial attachment. Multiple treatment modalities are advocated, involving exposure of the invasive defect, removal of the granulation tissue and sealing with various restorative materials. This report demonstrates conservative treatment of a patient presenting with peri-apical periodontitis in upper right central and lateral incisors, along with Class II invasive resorption defect cervically on the mesial aspect of the central incisor, as a result of trauma. As the patient was not willing for any surgical intervention, only ortho-grade root canal treatment was carried out in both teeth, with Calcium hydroxide as intra-canal medicament. At three year follow-up, the patient remains asymptomatic demonstrating radiographic evidence of infilling of defect with bone-like tissue. Within the limitations of this report, it was seen that this conservative method for halting the progression of invasive cervical resorption could be under taken in patients who are un-willing for surgical intervention or in whom surgery is contra-indicated.
