Antibiotic prescribing for endodontic infections: a survey of dental students in Italy

Antibiotic Over-Prescription by Dentists in the Treatment of Apical Periodontitis: A Systematic Review and Meta-Analysis

After pulp infection and necrosis, the passage of microbial antigens into the periapical space causes apical periodontitis (AP). Most of the clinical forms of AP can be managed without prescribing antibiotics, only with root canal treatment and abscess drainage or, where appropriate, tooth extraction. However, the scientific literature provides evidence of inappropriate antibiotic prescriptions by dentists in the management of apical disease.

OBJECTIVES

The aim of this systematic review and meta-analysis was to analyze the global pattern of antibiotic prescription in the treatment of apical disease.

METHODS

PRISMA Guidelines were followed to carry out this systematic review. The research question was as follows: What is the pattern of antibiotic prescription by dentists in the treatment of the different clinical forms of apical periodontitis? A systematic search was conducted on MEDLINE/PubMed, Wiley Online Database, Web of Science and Scopus. All studies reporting data about the pattern of antibiotic prescription by dentists in the treatment of apical disease were included. The meta-analyses were calculated using the Open Meta Analyst version 10.10 software. Random-effects meta-analyses were performed. The risk of bias was assessed using the Newcastle-Ottawa Scale. The certainty of evidence was assessed using GRADE.

RESULTS

The search strategy identified 96 articles and thirty-nine cross-sectional studies fulfilled the inclusion criteria. The overall percentage of antibiotic prescriptions by dentists in cases of symptomatic AP was 25.8%, and 31.5% in cases of asymptomatic AP with sinus tract present. The percentage of dentists prescribing antibiotics in cases of acute apical abscess with no/mild symptoms was 47.7%, whereas, in cases of acute apical abscess with moderate/severe symptoms, 88.8% of dentists would prescribe antibiotics. Endodontists prescribe antibiotics at a lower rate than general practitioners. The total risk of bias was considered moderate, and the final rating for the certainty of the evidence was low.

CONCLUSIONS

Dentists worldwide are over-prescribing antibiotics in the management of apical disease. It is necessary to improve antibiotic prescribing habits in the treatment of endodontic infections, as well as educational initiatives to encourage the rational and appropriate prescription of antibiotics in periapical diseases.

Systemic Antibiotic Use in Acute Irreversible Pulpitis: Evaluating Clinical Practices and Molecular Insights

This scoping review systematically evaluates the use of systemic antibiotics in treating acute irreversible pulpitis, integrating clinical practice patterns with recent molecular insights. We analyzed clinical evidence on antibiotic prescription trends among dental professionals and examined molecular research advancements in relation to pulpitis. This review is intended to bridge the gap between clinical practice and molecular research, guiding more evidence-based approaches to treating acute irreversible pulpitis. Electronic databases were searched for relevant articles published in English based on the objective of the review. A second search using all identified keywords and index terms was undertaken across all the included databases. In addition, a reference list of identified articles was searched. Studies including original research, systematic reviews, meta-analyses, clinical trials, and observational and retrospective studies, all written in English and published from 2010 onwards, were included, and an analysis of the text words contained in the titles and abstracts of the retrieved papers and of the index terms used to describe the articles was performed. A total of N = 53 articles were selected. Altogether, N = 43 (76.79%) articles were cross-sectional studies, N = 4 (11.11%) were systematic reviews, and N = 3 (5.36%) were guidelines. The most frequent level of evidence was level VI (N = 43 (76.79%). The mean percentage of dentists who prescribed antibiotics to treat acute irreversible pulpitis was 23.89 ± 23.74% (range: 0.05-75.7). Similarly, for specialists, it was 22.41 ± 15.64 (range 2.2-50.4), and the percentage for undergraduates was 17.52 ± 20.59 (range 0-62.6). The significant developments in research models for pulpitis research and the characterisation of biomarkers have led to better management strategies. Concurrently, significant advancements in molecular research provide new understandings of pulpitis, suggesting alternative therapeutic approaches. Although there are guidelines available, increased rates of antibiotic prescription are still prevalent around the globe.

Knowledge, attitudes and behaviours regarding antibiotics use among Cypriot university students: a multi-disciplinary survey

BACKGROUND

The present study aims to investigate the knowledge and attitudes towards antibiotics among students studying medicine, dentistry, and pharmacy at the Near East University in Northern Cyprus. The influence of personality characteristics on antibiotic use were also evaluated, in order to identify predictors of antibiotic misuse.

METHODS

Students were enrolled in the study during the 2020-2021 academic year. Study participants were asked to complete an online questionnaire that measured their knowledge, attitudes and practice (KAP) towards antibiotic use and antibiotic resistance. The KAP of students from the three faculties were compared using Kruskall-Wallis H statistics, Mann-Whitney U statistics, and Spearman's rho. The influence of personality traits on the propensity to use antibiotics without a prescription, as well as their attitudes and knowledge of antibiotic use and misuse, were also investigated.

RESULTS

In total, 314 students completed the survey, 52% of which were female. The mean age of the students was 20.5 years. The results showed that among the different disciplines, medical students were significantly more knowledgeable about pharmacological agents, compared to dentistry and pharmacy students, while pharmacy students were more knowledgeable about the effectiveness of antibiotics against different pathogenic microorganisms. All student groups were aware of how antibiotic resistance develops and their role as healthcare personnel in implementing measures against resistance. Appropriate antibiotic use among the student community correlated with study year, highlighting the importance of knowledge and education in the prevention of antibiotic resistance. Personality traits were found to be a contributing factor in students' tendency to use antibiotics without a prescription.

CONCLUSION

This study demonstrates the importance of conveying knowledge about antimicrobials in the education programmes of future dentists, pharmacists and physicians.

Applying the Kirkpatrick model to evaluate dental students' experience of learning about antibiotics use and resistance

INTRODUCTION

"Antibiotic resistance" is of main concern in global health and that it could hinder the achievement of sustainable development goals. One of the reported contributing factors is the irrational prescribing behaviour of healthcare professionals including dentists. Efforts to design and evaluate effective educational programmes for undergraduate dental students about appropriate prescribing behaviour during their early educational years could mitigate the risk of antibiotic resistance.

MATERIALS AND METHODS

A total of 322 students participated in the study. Their knowledge of antibiotics and antibiotic resistance was assessed. Students received a specially designed, interactive educational programme. The success of the programme was assessed after the educational sessions and 2 years later using Kirkpatrick's four-level evaluation model.

RESULTS

This study is the first study to use Kirkpatrick model to evaluate an educational programme for dental students. The results of the first level of evaluation showed an overall satisfaction score of 82.1%. The second level revealed an increase in the percentage of correct answers after the educational sessions from 68.3% to 80%, and significant agreement with responsible antibiotics usage (p-value = .020, Effect size = 0.121). The third level showed that the percentage of correct answers 2 years later was 87.5%. The fourth level confirmed the success of the programme as 88.9% of participants reported using the knowledge gained from the programme when prescribing antibiotics.

CONCLUSIONS

Our study emphasises the success of the used educational programme and highlights the need for educational interventions in the under graduate dental curriculum.

Knowledge and attitudes of Croatian Dentists Regarding Antibiotic Prescription in Endodontics: A Cross-sectional Questionnaire-based Study

OBJECTIVES

To assess dentists' level of knowledge and practice concerning antibiotic usage in endodontics using the European Society of Endodontology position statement as a reference.

MATERIALS AND METHODS

A cross-sectional study was conducted in the form of an electronic questionnaire consisting of 23 questions, including dentists' demographic and professional characteristics, attitudes as well as experiences regarding antibiotics in endodontics. Data were evaluated by the Mann-Whitney test or the Kruskal Wallis 1-way ANOVA, α = 5%.

RESULTS

The overall mean self-reported knowledge of antibiotics usage in endodontics was 11.7±2.5 points, out of a maximum possible score of 23. The factors associated with a higher knowledge were: age (P≤0.001), clinical experience (P≤0.001), specialist training (P=0.008), and adherence to the guidance on the use of systemic antibiotics in endodontics (P=0.006). Dentists who specialized in endodontics (16.1±2.2) achieved higher levels of knowledge.

CONCLUSION

Knowledge on antibiotic usage in endodontics among dentists in Croatia is insufficient. There is a need for continuing education on the use of antibiotics among general dentists.

Cationic Antimicrobial Peptides Are Leading the Way to Combat Oropathogenic Infections

Oral dental infections are one of the most common diseases affecting humans, with caries and periodontal disease having the highest incidence. Caries and periodontal disease arise from infections caused by oral bacterial pathogens. Current misuse and overuse of antibiotic treatments have led to the development of antimicrobial resistance. However, recent studies have shown that cationic antimicrobial peptides are a promising family of antibacterial agents that are active against oral pathogenic bacteria and also possess less propensity for development of antimicrobial resistance. This timely Review has a focus on two primary subjects: (i) the oral bacterial pathogens associated with dental infections and (ii) the current development of antimicrobial peptides targeting oral pathogens.

An investigation into possible factors that may impact on the potential for inappropriate prescriptions of antibiotics: a survey of general dental practitioners' approach to treating adults with acute dental pain

Objective To investigate factors that might influence inappropriate prescriptions of antibiotics (ABs) by UK-based general dental practitioners (GDPs) in their management of acute dental pain in adults in primary dental care.Methods A questionnaire was circulated via social media to UK-based GDPs. The questionnaire examined GDPs' likelihood of issuing an inappropriate AB in two hypothetical clinical scenarios.Results A total of 205 questionnaires were completed, of which 198 were included for analysis. The resulting data were analysed to try and identify factors that correlated with an increased likelihood of an inappropriate AB prescription being issued for each clinical scenario. The results suggested the following factors as being associated with a statistically greater chance of the survey respondent issuing an inappropriate AB prescription: no postgraduate qualification; received their primary dental qualification from a non-UK university; scheduled appointments of less than 20 minutes; and low confidence in their ability to provide adequate local anaesthesia for the patients in the clinical scenario.Conclusions Four factors were shown to be associated with dentists' stated intention to prescribe ABs for acute dental pain, not in accordance with guidance. These results should guide further research to understand the significance of appropriate AB prescribing on the quality of urgent dental care. While the total number of respondents was too low to enable the results to be generalised, it is hoped that the results may help guide future research. Further studies could focus on these factors to understand more about their impact on the urgent care of adult patients in pain. The impact of the restrictions caused by the response to COVID-19 needs to be considered.

Antibiotic Prescribing Practices in Endodontic Infections: A Survey of Dentists in Serbia

The study goal was to provide an overview of antibiotic prescribing practices of Serbian dentists when treating endodontic infections and to disseminate the current ESE (European Society of Endodontology) recommendations to the study participants. A link to an online questionnaire was sent to 628 Serbian dentists whose email addresses were publicly available on the Internet, 158 of whom responded to the survey, resulting in a 25.16% response rate. The significance of possible associations was assessed via the Chi-squared test and Cramer’s V measure of association, with p < 0.05 considered as statistically significant. According to the study findings, 55.7% of respondents prescribed a 5-day antibiotic course. Moreover, Amoxicillin 500 mg was the first-choice antibiotic for 55.1% of the respondents, followed by Clindamycin 600 mg (18.4%). For patients allergic to penicillin, 61.4% of respondents prescribed Clindamycin. Statistically significant differences emerged only in relation to acute apical abscess with systemic involvement, whereby dentists aged 46–55 were least likely to prescribe antibiotics in these clinical situations (p = 0.04). Analyses further revealed that recommendations for safe antibiotic prescribing practices were not always followed, as in certain cases, patients were given antibiotics even when this was not indicated. These findings highlight the need for additional education on responsible antibiotic use to prevent bacterial resistance.

Evaluation of the knowledge of final-year dental students on the use of antibiotics in endodontics in Turkey

The knowledge of the final-year dental students on antibiotic use in endodontics in Turkey was assessed. The study was conducted at 20 Dentistry Faculties. A questionnaire was sent to the universities including the concerning several scenarios about endodontic cases. 1113 final-year dental students participated in the study. Respondents' significant choice was not to administrate antibiotics in endodontic treatments of symptomatic irreversible pulpitis, pulp necrosis, acute apical periodontitis, chronic apical abscess with or without sinus tract, retreatment, inadequate local anaesthesia and patient requests (P > 0.05). In acute apical abscess (AAA) with diffuse cases, choice of antibiotic administration was statistically higher (P < 0.05), while in AAA-localised cases, the ratio of antibiotic administration versus non-administration was similar. Amoxicillin was found to be the first-choice antibiotic in patients without medical allergies, whereas in allergic patients the first choice was clindamycin. Final-year dental students have fundamental knowledge on the antibiotic administration in endodontics.

Shift in antibiotic prescription at a University Dental Clinic in Norway 2013-2017

A considerable number of prescriptions for antibiotics are issued by dentists. Educational institutions have a special responsibility to promote informed attitudes among dental students towards prescribing antibiotics. The purpose of this study was to analyze the antibiotic prescriptions issued during a 5-year period (2013-2017) at a University Dental Clinic (UDC) in Norway. All patient records containing prescriptions for patients ≥18 yr of age as of 2013-2017 were identified through an electronic search. In total, 6,014 patient record lines containing prescriptions were obtained, 1,047 (17.4%) of which were prescriptions for systemic antibiotics. These patient record lines were analysed to identify the specific antibiotic prescribed, the indication or diagnosis for which it was prescribed, and whether microbiological testing (to determine antibiotic sensitivity) had been carried out. Acute infections were the most common context for prescribing antibiotics. Surprisingly, prophylaxis was the second most frequent reason stated. Disease related to pulp necrosis (43%) and postoperative infections (26%) was the most common diagnosis for therapeutic antibiotic prescriptions. Antibiotic therapy was more commonly used to treat peri-implantitis than to treat periodontitis. Only 60% of the clindamycin prescriptions were issued to patients with penicillin allergy. Further studies are warranted concerning antibiotic use at UDC because this can probably be more restrictive, in particular concerning usage related to antibiotic prophylaxis. Microbiological testing should be performed before administration of antibiotic therapy for periodontitis and peri-implantitis. The reason for prescribing antibiotics should always be stated in the patient's record lines.

Medication knowledge among dental students in Australia-a cross-sectional study

PURPOSE/OBJECTIVES

Prescribing medicine is integral to clinical dentistry. Future dental practitioners need to have a thorough knowledge of how to prescribe safely and effectively. To date, medication knowledge among dental students in Australia has not been assessed at a national scale.

METHODS

Australian dental students were invited to undertake the survey comprising 12 multiple choice questions to investigate their medication knowledge. A total of 185 responses were received. The questions were 11 clinically relevant questions and 1 opinion-based question with 4 options from which to select. Results were analyzed using descriptive statistics.

RESULTS

The 185 respondents had a mean correct response of 6.77 ± 1.8 (range: 2-11 out of 11). Out of 185 students, 142 students (77%) answered more than half of the questions correctly. Only 1 student (1%) answered all 11 questions correctly. There were 135 students (73%) who either agreed or strongly agreed that they would feel confident to prescribe safe and effective medication for their patients after having completed dental school.

CONCLUSION

Most respondents answered more than half, but not all, of the clinical questions correctly. Despite this, many reported confidence in their prescribing skills. Future research needs to further investigate pharmacotherapeutic knowledge to determine detailed knowledge gaps in prescribing.

Application of a new system for classifying root canal morphology in undergraduate teaching and clinical practice: a national survey in Malaysia

AIM

To evaluate and compare the feedback of final year undergraduate dental students in eight Malaysian dental schools on the application of a new system for classifying root canal morphology in teaching and clinical practice.

METHODS

One PowerPoint presentation describing two classification systems for root canal morphology (Oral Surgery Oral Medicine Oral Pathology, 1974 38, 456 and its supplemental configurations, International Endodontic Journal 2017, 50, 761) was delivered to final year undergraduate dental students in eight dental schools in Malaysia by two presenters (each presented to four schools). To examine students' feedback on the utility of each system, printed questionnaires consisting of six questions (five multiple choice questions and one open-ended question) were distributed and collected after the lecture. The questionnaire was designed to compare the classification systems in terms of accuracy, practicability, understanding of root canal morphology and recommendation for use in pre-clinical and clinical courses. The exact test was used for statistical analysis, with the level of significance set at 0.05 (P = 0.05).

RESULTS

A total of 382 (out of 447) students participated giving a response rate of 86%. More than 90% of students reported that the new system was more accurate and more practical compared with the Vertucci system (P < 0.001). Overall, 97% of students reported the new system helped their understanding of root and canal morphology compared with the Vertucci classification (P < 0.001). Over 97% of students recommended the use of the new system in teaching, pre-clinical courses and clinical practice (P < 0.001). Except for two schools, no significant difference was detected between the responses of students for all questions at the different schools (P > 0.05). The students' responses for all questions were almost similar for both presenters (P > 0.05).

CONCLUSIONS

The new system of International Endodontic Journal 2017, 50, 761 for classifying root and canal morphology was favoured by final year undergraduate dental students in Malaysia. The new system has the potential to be included in the undergraduate endodontic curriculum for teaching courses related to root and canal morphology.

The Effectiveness of Online Course Intervention to Improve Knowledge of Antimicrobial Resistance among Dental Students, in Comparison to Reference Group Using a Randomized Controlled Trial

AIM

This study aimed to assess the effectiveness of a recognised antimicrobial resistance (AMR) online module on knowledge and perception among dental students, using a randomised controlled trial study design.

METHODS

Dental students (n = 64, aged 21-25 years) in clinical years agreed to participate in this triple-blinded, parallel, randomised controlled trial. There were 34 students in the study group and 30 students in the control group. The study group participated in an online course covering information about AMR, while students in the control group received another online course about microorganisms in dentistry. Both groups were assessed three times using online questionnaires: before the intervention (T1), after the intervention (T2), and two months later (T3). Each one of T1, T2 and T3 had 22 questions. The questions were repeated each time in T1, T2, and T3 asking about AMR but with different question format, to avoid the possibility of students to memorise the answers.

RESULTS

The mean (m) of correct answers for all students on T1 was 12.56, with standard deviation (SD) of 3.2. On T2, m = 14.03 and SD = 3.85, and on T3, m = 14.36 and SD = 3.71. Scores ranged from 0 to 22. The participants in the study and control groups showed significant score improvements from T1 to T2, immediately after the intervention, but there was no significant difference between T2 and T3. The study group students' scores did not improve significantly from T1 to T3, in contrast to the control group students' scores. More importantly, there was no significant difference in improvement from T1 to T2 when comparing the study and control groups.

CONCLUSION

Online courses might not be reliable learning methods for ensuring the optimal levels of AMR knowledge that are needed by dental practitioners.
