The trends in antibiotic use by general dental practitioners in the Czech Republic (2006–2012)

Changes in Antibiotic Redemption Related to Hungarian Dental Care During COVID-19

INTRODUCTION AND AIMS

Antibiotic resistance is a global health problem that can affect individuals, health systems, and the economy. Our aim was to investigate how the redemption of antibiotics and the associated dental care changed during COVID-19 in Hungary.

METHODS

The ICD codes for the infections for which antibiotics should be prescribed in dental care were identified based on the professional recommendation. The database was provided by the National Health Insurance Fund Manager of Hungary. Pearson's chi-squared test with Bonferroni correction was used to compare both the redemption of antibiotics and the associated dental care based on the recommendations in the year 2020 of the COVID-19 and the 2 preceding years.

RESULTS

There were fewer antibiotic redemptions and associated dental care in 2020 than in 2018 and 2019. The ratio of professionally relevant and nonrelevant antibiotics redeemed did not change significantly between 2018 and 2019, but the proportion of antibiotics redeemed following recommendations increased significantly during the COVID-19 year of 2020 compared to the previous 2 years. The proportion of all dental care involving antibiotic redemptions increased significantly from 2018 to 2019, and then showed a further increase in 2020. The sex and age of the patient did not affect these findings, while the type of dental care did alter the trends in some cases.

CONCLUSIONS

Antibiotics in dentistry are required only for very low proportion of cases, due to the nature of dental care where most infections such as caries and periodontal disease could be managed without resorting to antibiotics. Antibiotic redemptions during COVID-19 pandemic period increased compared to the pre-pandemic period in Hungary. Therefore, Hungarian policy makers need to develop control systems to promote the correct use of antibiotics in dental care.

CLINICAL RELEVANCE

It is important to reduce unjustified use of antibiotics so as to curb the emergence of antibiotic resistance organisms.

Central and Eastern European Migrants in the United Kingdom: A Scoping Review of the Reasons for Utilisation of Transnational Healthcare

BACKGROUND

An estimated 2.2 million people from Central and Eastern Europe (CEE) live in the United Kingdom. It has been documented that CEE migrants underutilise health services in the United Kingdom and, as an alternative, seek healthcare in their home country. However, reasons for seeking healthcare abroad are not always clear. This review aims to identify the reasons for the uptake of transnational healthcare among CEE migrants resident in the United Kingdom.

METHODS

Informed by discussions with community members, medical stakeholders and academics, a systematic scoping review was undertaken following the nine-stage Joanna Briggs Institute framework for scoping reviews. A search strategy with MeSH terms, where relevant, was used and adapted in five academic databases, two grey literature databases and Google Scholar. Included records encompassed four concepts: migration, CEE nationalities, UK nations and healthcare utilisation, which were written in English and published between May 2004 and 2022. Data from the literature were coded, grouped and organised into themes.

RESULTS

A total of 16 publications fulfilled the inclusion criteria. There is evidence that some CEE migrants exclusively use healthcare services in the United Kingdom. However, many CEE migrants utilise healthcare both in the United Kingdom and their country of origin. Four themes were identified from the literature as to why migrants travelled to their country of origin for healthcare: cultural expectations of medical services, distrust in the UK NHS, barriers and transnational ties.

CONCLUSION

Push factors led CEE migrants to seek healthcare in their country of origin, facilitated by ongoing transnational ties. CEE migrants frequently combine visits to their country of origin with medical appointments. Utilising healthcare in their country of origin as opposed to the United Kingdom can result in fragmented and incomplete records of medications, medical tests and surgeries and risk of unnecessary treatments and complications. This review highlights the need for more targeted health outreach with CEE groups within the United Kingdom, as well as the need for further research on the impact of national events, for example, COVID-19 and Brexit, on transnational healthcare-seeking behaviours.

PATIENT OR PUBLIC CONTRIBUTION

The concept for this scoping review was informed by discussions with community members, medical professionals and academics, who identified it as a current issue. The results of this scoping review were discussed with healthcare stakeholders.

Trends and patterns of antibiotic using from 2014 to 2018 in stomatology hospitals of China

OBJECTIVE

To analyze trends of antibiotic consumption and expenditure in Chinese stomatology hospitals between 2014 and 2018 with a longitudinal study design, and show the impacts of the comprehensive policy on dental antibiotic use in China.

SUBJECT AND METHODS

Consumption was quantified as the number of daily defined doses (DDDs) and expenditure as the procurement costs, using medical institutions' drug procurement data from the Chinese Monitoring Network for Rational Use of Drugs. Descriptive statistics was employed and the compound annual growth rate (CAGR) was calculated to show the average annual growth rate.

RESULTS

Between 2014 and 2018, overall antibiotic consumption increased from 842.6 thousand DDDs to 1376.7 thousand DDDs (p < 0.001) and expenditure increased from 11.6 million RMB to 20.9 million RMB (p < 0.001), where other β-lactam antibacterials accounted for the largest proportion of total consumption (37.1%-50.1%) and expenditure (52.9%-66.6%), and also increase the largest (CAGR = 18.4%, p < 0.001). The proportion of oral antibiotics was nearly 9 times of parenteral antibiotics in consumption (CAGR = 0.3%, p = 0.023) and only 2 times in expenditure (CAGR = -1.7%, p = 0.112). The non-restricted group accounted for more than 90% of consumption (CAGR = 0.6%, p < 0.001). In 2018, oral first-generation cephalosporins (22.8%), oral imidazole derivatives (22.3%), and oral second-generation cephalosporins (19.2%) were the most frequently used antibiotic classification, while parenteral second-generation cephalosporins were top one (19.8%) for expenditure. At chemical substance levels, the consumption of oral cefradine ranked top one (21.4%) and parenteral cefuroxime accounted for the largest proportion of expenditure (14.5%) in 2018. Oral cefradine, oral metronidazole, and oral cefaclor were the top three frequently consumed antibiotics throughout the five years.

CONCLUSIONS

Despite the potential antibiotic overuse, the comprehensive antibiotic stewardship regulations of China got a satisfactory and better performance in dental practices. More effort is needed to establish more explicit guidelines to improve antibiotic stewardship, such as priority recommending amoxicillin and its derivatives for endodontic infections.

Antibiotics Prescribing Pattern and Quality of Prescribing in Croatian Dental Practices-5-Year National Study

PURPOSE

Antibiotic resistance is one of the biggest threats to global health today. The aim of this study was to analyze antibiotic prescribing patterns and quality of prescribing in Croatian dental practices over a 5-year period.

METHODS

This is a retrospective observational study based on the analysis of the electronic prescriptions (medicines in ATC groups J01 and P01) from dental practices in Croatia prescribed from 1 January 2015 to 31 December 2019. Prescriptions were retrieved from the Croatian Health Insurance Fund (HZZO). The analyses included the number of prescriptions, type and quantity of prescribed drugs, indication, and the patient's and prescriber's characteristics.

RESULTS

The consumption increased from 1.98 DID in 2015, to 2.10 DID in 2019. The most prescribed antibiotic was Amoxicillin with clavulanic acid followed by Amoxicillin, Clindamycin, Metronidazole and Cefalexin. The analyses showed that 29.79% of antibiotics were not prescribed in accordance with the contemporary guidelines for the proper use of antibiotics. Additionally, 22% of antibiotics were prescribed in inconclusive indications.

CONCLUSION

The research showed an increase in antibiotic consumption over five years along with unnecessary prescribing of antibiotics in cases with no indications for its use. The development of national guidelines for antibiotic use is necessary.

Antibiotics Knowledge, Usage, and Prescription Patterns Among Dental Practitioners in Hyderabad, South India

BACKGROUND

Antimicrobial resistance is a pertinent issue in the healthcare sector, accounting for 1.27 million patient deaths worldwide. Dental practitioners account for 3% to 11% of total antibiotic prescriptions. Therefore, this study aimed to specifically assess their knowledge of antibiotic prescriptions, guidelines, and clinical practices.

METHOD

Before conducting this knowledge, attitude, and practice (KAP) survey, study approval was obtained from the Scientific Review Board of Saveetha Dental College and Hospitals, Chennai, India. A total of 200 participants were randomly selected from the list of Indian Dental Association (Hyderabad chapter), and dental colleges, dental conferences, and peer suggestions. We received a total of 130 responses by the end of the survey.

RESULTS

The survey revealed gaps in practitioners' KAP. Of those surveyed, 83 (63.85%) of the practitioners kept themselves updated about antibiotic guidelines and news, but many (94, 72.31%) were unaware of the WHO's access, watch, reserve (AWaRe) and antimicrobial stewardship concepts (103, 79.23%). A total of 111 (85.38%) practitioners considered cross-reactions with other medications, yet only 28 (21.5%) practitioners tested patients for antibiotic sensitivity. While 64 (49.23%) practitioners encountered patients who did not respond to antibiotics, 84 (64.62%) practitioners encountered patients who demanded antibiotics.

CONCLUSION

This study highlights the lack of awareness about the WHO's AWaRe classification and antimicrobial stewardship among the majority of dental practitioners across Hyderabad. Misuse or overuse of antibiotics was indicated in this survey by both patients and dental practitioners. Prioritizing updates on antibiotic knowledge and guidelines and awareness of their use is important. It is essential to educate patients about the ill effects of self-prescribing antibiotics. Dental practitioners need to consider cross-reactions and antibiotic-sensitivity testing before prescribing antibiotics. Labeling the sensitivity of a particular antibiotic for specific microbes on packaging can help reduce misuse and the use of antibiotics for the wrong indications.

Antibiotic prescription after tooth extraction in adults: a retrospective cohort study in Austria

BACKGROUND

Broad spectrum antibiotics are often used for the prophylaxis of infectious endocarditis and treatment of odontogenic infections, but there are limited data related to antibiotic use and adherence to prescription guidelines.  METHODS: Data from patients with tooth extraction between 2014 and 2018 were selected from a database of a regional health insurance fund. We created three data sets, one based on all tooth extractions, one on multiple teeth extractions, and one including only single tooth extraction. After data collection, descriptive analysis was carried out. The differences in prescription pattern of antibiotic medicine were tested by χ2 test, Student´s t-test or ANOVA.

RESULTS

From 43,863 patients with tooth extraction, 53% were female, and 3,983 patients (9.1%) filled a prescription for antibiotic medicine. From 43,863 patients, 157 patients (0.4%) had endocarditis risk, but only 8 patients of these (5.1%) filled an antibiotic prescription. In total, 9,234 patients had multiple and 34,437 patients had only one tooth extraction. Patients with more than one tooth extraction received more often antibiotic treatment (10.7%) compared to those with single tooth extractions (χ2 = 36; p < 0,001). Patients with more than one tooth extraction were older, however, younger patients received antibiotics more frequently (t = 28,774, p = 0.001). There was no relationship with endocarditis risk status. Clindamycin and amoxicillin/clavulanic acid were the most frequently prescribed antibiotic medicines.

CONCLUSIONS

In this retrospective cohort study, dentists did not discriminate prophylactic antibiotic prescription with regard to endocarditis risk status. A factor influencing prescribing behaviour of antibiotic medicines was the number of extracted teeth.

Attitudes towards Antibiotic Prescription and Antimicrobial Resistance Awareness among Italian Dentists: What Are the Milestones?

Antimicrobial resistance is a growing phenomenon, often associated with the improper prescription of antibiotics, prescribed by those who do not follow the guidelines for antibiotic stewardship. The aim of this study was to evaluate the current attitude towards antibiotic prescribing and antimicrobial resistance awareness among Italian dentists. An online questionnaire was distributed to Italian dentists from September to December 2021. The questionnaire was composed of three main sections. The first part was focused on demographic characteristics, the second part on prescription habits, and the third part on the dentists’ knowledge regarding the phenomenon of antimicrobial resistance. A chi-square test was used to find associations between different variables. The level of significance was set at p < 0.05. A total of 382 dentists completed the questionnaire. The main reasons for antibiotic prescribing were for abscesses (39.6%), extractions (24.5%), and pulpitis (14.1%). The majority of participants (85.3%) reported prescribing macrolides in the case of a penicillin allergy. Most dentists (98.9%) were aware of the antimicrobial resistance phenomenon, but only 7.4% of them consulted the guidelines for prescribing antibiotics. This study demonstrates that the same trend exists in Italy as in other countries in terms of the high prevalence of misuse and overuse of antibiotics, and that Italian dentists utilize a range of antibiotic management strategies.

Trends in Australian dental prescribing of antibiotics: 2005-2016

BACKGROUND

Prescribing of antibiotics by dentists for surgical prophylaxis or as an adjunct to managing dental infections is a substantial part of the overall landscape for prescribed antibiotics in health care settings.

METHODS

We explored trends in the antibiotic prescribing patterns of Australian dentists over the 12-year period, 2005-2016. We obtained data on dispensed prescriptions of antibiotics from registered dentists subsidized on the Pharmaceutical Benefits Scheme.

RESULTS

Australian dentists were responsible for almost 7 million dispensed prescriptions of antibiotics over 12 years; an average of 24 prescriptions per year per dentist. The most commonly prescribed antibiotic was amoxicillin, followed by amoxicillin + clavulanic acid and metronidazole. These top three antibiotics constituted more than 80% of all antibiotics prescribed and their use increased dramatically over time. There was a large increase in the prescribing of broad-spectrum antibiotics over time, most of which occurred from 2011 to 2016.

CONCLUSIONS

Excessive prescribing of broad-spectrum antibiotics runs contrary to national antimicrobial stewardship (AMS) initiatives and guidelines. Multifaceted educational strategies are essential to align prescribing with current best practice. High-level evidence to inform clear guidelines on antibiotic prescribing in dental infections, with audit and feedback, should reduce the inappropriate use of antibiotics in dentistry.

Changes in Antibiotic Prescription After Tooth Extraction: A Population-Based Study from 2002 to 2018

OBJECTIVE

Microbial resistance due to antibiotic misuse is a worldwide problem. This study aimed to examine the trends in antibiotic prescription after tooth extraction in Korea.

METHODS

From the database of National Health Insurance Sharing Service, patients who underwent tooth extraction from 2002 to 2018 were selected as subjects, and 10% of them were selected via stratified sampling based on sex and age. Overall, 15,838,529 cases were observed for annual antibiotic prescription and broad-spectrum antibiotic prescription patterns. Additionally, standardized annual antibiotic use was calculated using a defined daily dose.

RESULTS

Prescriptions were issued in 13,429,770 (84.8%) of the tooth extraction cases, of which 12,179,185 (90.7%) included antibiotics. Logistic regression analysis revealed that the likelihood of prescribing antibiotics after tooth extraction decreased in 2003 compared to 2002 (odds ratio, 0.95) but increased from 2004 to 2018. In the case of the broad-spectrum antibiotic prescription rate, there was no clear trend between 2002 and 2012 (odds ratio, 0.89-1.07); however, over the last 5 years, the likelihood of broad-spectrum antibiotic prescription has steadily increased. The value of antibiotics based on the defined daily dose of 1000 patients per day was calculated to be 4.39 in 2002, exhibiting a steady increase later and reaching 6.97 in 2018, whereas that of broad-spectrum antibiotics was 1.68 in 2002 and has since been on the rise; the highest was 3.82 in 2018.

CONCLUSIONS

Antibiotic use after tooth extraction increased over the last 17 years; additionally, the rate of prescribing broad-spectrum antibiotics has increased over the last 5 years.

Medication Prescribing Practices in Croatian Dental Offices and Their Contribution to National Consumption

Objectives

The objective of this study was to analyse the pattern of medication prescribing among dental practitioners in the Republic of Croatia and to compare it with general medical practice patterns at the national level.

Methods

Data on drug prescriptions were obtained from the Croatian Health Insurance Fund. The number of dentist prescriptions, the cost of medicine denominated in the national currency (Croatian Kuna [HRK]), and the number of packages and days prescribed have been included in the analysis.

Results

Results indicate that there was an increase in medication prescribing(+5.7%) by dentists, with antimicrobials comprising the majority, whereas national medical antimicrobial prescribing had slightly decreased. Antibiotics accounted for 80% of all dentists’ prescriptions, with penicillins being the most commonly prescribed. In particular, amoxicillin with clavulanic acid accounted for 56.4% of all antibiotics prescribed. Such broad-spectrum antibiotics were prescribed more frequently than those of narrow-spectrum. Antibiotics were followed by nonsteroidal anti-inflammatory drugs, with prescribing frequency for ibuprofen increasing by 75%.

Conclusion

Current trends show an increase in the overall prescription rate for all medications prescribed by dentists. The largest increase was observed for the broad-spectrum amoxicillin with clavulanic acid, and ibuprofen. As the apparent widespread use of broad-spectrum antibiotics by dentists in Croatia is in contrast to national and international recommendations for antibiotic stewardship, there is a need for further prospective investigation and possible provider education and guidelines.

The prescribing of antibiotics for endodontic infections by dentists in Turkey: a comprehensive survey

AIM

To investigate the antibiotic prescribing patterns for endodontic infections based on the reports of Turkish dentists.

METHODOLOGY

A survey consisting of 20 questions on general information and 13 questions on antibiotic prescribing patterns for endodontic cases was delivered to the e-mail addresses of general dentists and specialists via the database of the Turkish Dental Association. Collected data were analysed using Mc-Nemar-Bowker Test and multivariate ordinal logistic regression tests at the significance level of 0.05.

RESULTS

A total of 1007 responses were obtained from 17 827 dentists. The majority of the participants were general dental practitioners (GDP, 80%) whilst 8% were Endodontists. Gender, clinical experience, affiliations and speciality were significant risk factors for antibiotic prescription (P < 0.05). GDPs prescribed antibiotics twice as much as all specialists and members of public hospitals prescribed antibiotics three times more than specialists and clinical academics (P < 0.05). Amoxicillin with clavulanic acid was the most prescribed antibiotic (90%), followed by Ornidazole (25%). Clindamycin was the drug of choice for the patients with penicillin allergy (59%). Infection and fever control (76%), prophylaxis (44%) and avoiding swelling and trismus during endodontic treatment (26%) were the most common reasons for antibiotic prescriptions. Completing a course of prescribed antibiotics was recommended by most (75%). Infective endocarditis, immunosuppression, artificial heart valve and mitral valve prolapse were the main causes of prophylaxis in descending order. Uncontrolled and extensive use of antibiotics by patients (62%) was mentioned as the most effective reason for antibiotic resistance. Up to 10% of participants prescribed antibiotics for symptomatic irreversible pulpitis, asymptomatic apical periodontitis with or without endodontic treatment (8, 12 and 11%, respectively). Up to 20% of dentists prescribed antibiotics for symptomatic apical periodontitis when the pulp was vital or necrotic (13 and 23%, respectively). Almost one third of the participants prescribed antibiotics for symptomatic apical periodontitis of previously treated teeth with or without radiographic lesions whilst 34% prescribed antibiotics for acute apical abscess with localized swelling without systemic involvement.

CONCLUSIONS

The majority of dentists reported they prescribed antibiotics inappropriately. It is necessary to improve the knowledge of dentists about antibiotics and their indications in endodontics.

Antimicrobial stewardship in dental practice

BACKGROUND

Antibiotic resistance is a global public health problem that is responsible for increased patient morbidity and mortality and financial burden. Dental antibiotic prescribing contributes to approximately 10% of all antibiotic prescriptions, and an estimated 80% of that prescribing is deemed inappropriate. Dental antimicrobial stewardship (AMS) has an important role to play in international efforts to tackle antibiotic resistance. The aim of the authors was to comment on the implementation of AMS strategies in outpatient dental practices.

METHODS

The authors included previous studies regarding outpatient antibiotic stewardship, longitudinal studies quantifying dispensed dental antibiotic prescription use, and interventional studies aimed at implementing AMS interventions in dentistry.

RESULTS

Researchers in several studies conducted trials regarding the use of various interventions, mostly comprising a combination of audit, feedback, dissemination of guidelines, and educational components to improve dental prescribing.

CONCLUSIONS AND PRACTICAL IMPLICATIONS

In regard to the establishment of an AMS strategy, aspects to be considered should include raising awareness about the risks of unnecessary use of antibiotics. Engaging and educating the entire dental team and patients, as well as collaborating with other specialized professionals, are important elements. Context-specific interventions with a methodical and measured approach are ideal.

Discrepancy in Therapeutic and Prophylactic Antibiotic Prescribing in General Dentists and Maxillofacial Specialists in Australia

There are concerns that general dentists (GDs) and dental specialists may be prescribing antibiotics inappropriately. This study explored the prescribing habits and decision-making processes of GDs versus oral and maxillofacial surgeons (OMFSs). A case-based online questionnaire was used to examine the prescribing of therapeutic and prophylactic antibiotics in two clinical scenarios. Stratified and systematic sampling strategies were implemented to provide a representative sample. The final valid sample was 60 GDs and 18 OMFSs. The majority of OMFSs (61.1%) routinely prescribed antibiotics for the surgical removal of third molars, which was significantly greater than for GDs (23.5%). For implant placement procedures, 72.2% of OMFSs and 62.1% of GDs prescribed antibiotics. Amoxicillin was the most selected agent for both scenarios. All OMFSs would prescribe antibiotic prophylaxis for patients with uncontrolled diabetes mellitus in both cases, but only 56.0–63.0% of GDs would do this. GDs based prescribing decisions primarily on information from prescribing guides, while OMFSs relied more on information gained from specialist training. Surgical prophylaxis protocols differed considerably between groups. Both groups used surgical prophylaxis for some situations that are outside current recommendations. Education with regards to discrepancies between clinical practice and current guidelines for antimicrobial therapy is needed to progress antimicrobial stewardship.

Trends in Systemic Antibiotic Therapy of Endodontic Infections: a Survey among Dental Practitioners in Lithuania

Objectives

Prescription trends to certain antibiotic classes in Lithuania have been observed. Considering the potential contribution to antimicrobial resistance and the evidence of inappropriate prescriptions highlights, the periodical assessment of antibiotic consumption trends is required. The aim of this study was to assess prescription behaviours of Lithuanian general dental practitioners concerning the systemic antibiotic therapy of endodontic infections.

Material and Methods

A sample of 198 Lithuanian dentists, registered on the database of the Lithuanian Dental Chamber, provided anonymous information about their clinical work by means of an online questionnaire.

Results

Among the participants, antibiotics were prescribed in less than 20% of endodontic cases. Most common diagnosis for the prescription was symptomatic apical periodontitis with periostitis (90%) and apical abscesses with systemic involvement (54%). Amoxicillin and co-amoxiclav were the preferred choices for the antimicrobial therapy. The preference of clavulanic acid combination over simple usage of amoxicillin is increasing relative to the participants age (P = 0.016) and working experience (P = 0.008). Clindamycin is prescribed in cases of allergy to beta-lactams. Practitioners with less years of clinical activity were more likely to prescribe antibiotics for spreading infections, than their associates with more than 10 years of practice (P < 0.001).

Conclusions

Clinicians of higher age were found to be more likely to prescribe broad-spectrum antibiotic combinations compared to their younger associates. The majority of practitioners were aware of the clinical recommendations.

Prescription of antibiotics after tooth extraction in adults: a nationwide study in Korea

Objectives

This study aimed to understand the nationwide patterns of antibiotic prescription after tooth extraction in adult patients.

Materials and Methods

This study analyzed dental records from the National Health Insurance Service–National Sample Cohort (NHIS–NSC) database on 503,725 tooth extractions performed in adults (≥19 years) during 2011–2015. Patient sex, age, household income, systemic disease (diabetes mellitus and hypertension), type of dental institution, region of dental institution, year of prescription, and type of tooth extraction procedure were considered. The antibiotic prescription rate and broad-spectrum antibiotic prescription frequency were analyzed using chi-squared tests. Factors affecting the prescription of broad-spectrum antibiotics were evaluated using multivariate logistic regression analysis.

Results

The rate of antibiotic prescription after tooth extraction was 81.85%. Penicillin was most commonly prescribed (45.25%), followed by penicillin with beta-lactamase inhibitors (18.76%), metronidazole (12.29%), and second- to fourth-generation cephalosporins (11.52%). The proportion of broad-spectrum antibiotics used among all prescribed antibiotics was 45.88%.

Conclusion

The findings of this study demonstrate that the rate of antibiotic prescription after tooth extraction is higher in Korea than in other countries. Furthermore, broad-spectrum antibiotics are used more frequently, which may indicate unnecessary drug prescription, an important contributor to antibiotic resistance.

Prophylactic antibiotics for staged bone augmentation in implant dentistry

Background: The objective of the study was to assess the effect of prophylactic antibiotics on the outcome of bone augmentation and subsequent dental implant placement by combining the recommended quality assessment methods for systematic reviews and primary studies.Materials and methods: This is a complex systematic review in which systematic reviews as well as primary studies are scrutinised. A search of Medline (OVID), The Cochrane Library (Wiley) and EMBASE, PubMed and Health technology assessment (HTA) organisations as-well as a complementary hand-search was carried out. Selected primary studies were assessed using GRADE. Each study was reviewed by three authors independently.Results: Abstract screening yielded six potential systematic reviews allocated for full-text inspection. A total of ten primary studies were read in full-text. No relevant systematic reviews regarding the topic of this article were found. The quality assessment resulted in two primary studies with a moderate risk of bias. Of the two studies with a moderate risk of bias, one compared a single dose of clindamycin 600 mg preoperatively with the same preoperative dose followed by four doses of 300 mg every 6 h. The second study compared a single dose prophylaxis of two different types of antibiotic compounds.Conclusion: In conclusion, the scientific evidence regarding the use of antibiotic prophylaxis for reducing the risk of infection in conjunction with bone augmentation procedures during dental implant placement is very limited. The infection rate as compared to nonusage of prophylactic antibiotics, selection of the most suitable compound, and the optimal duration of prophylactic treatment is still unknown.

Longitudinal antibiotic prescribing trends among US dental specialists within a pharmacy benefits manager, 2013 through 2015

BACKGROUND

Reducing inappropriate antibiotic prescriptions (Rxs) is a major quality improvement initiative in the United States. Tracking antibiotic prescribing trends is 1 method of assessing improvement in antibiotic prescribing. The purpose of this study was to assess longitudinal antibiotic prescribing practices among dental specialists.

METHODS

This was a retrospective ecological longitudinal trend study. The authors calculated monthly systemic antibiotic Rx counts, and rates per 100,000 beneficiaries, from a pharmacy benefits manager in the United States from 2013 through 2015. The authors calculated average annual antibiotic Rx rates (AARs) for the 3-year study period. The authors used a quasi-Poisson regression model to analyze antibiotic Rx trends. The authors quantified seasonal trends, when present, via peak-to-trough ratios (PTTRs).

RESULTS

Dental specialists prescribed 2.4 million antibiotics to the cohort of 38 million insurance beneficiaries during the 3-year study period (AAR = 2,086 Rxs per 100,000 beneficiaries). Oral and maxillofacial surgeons prescribed the most antibiotics (1,172,104 Rxs; AAR = 1,018 Rxs per 100,000 beneficiaries), followed by periodontists (527,038 Rxs; AAR = 457 Rxs per 100,000 beneficiaries), and endodontists (447,362 Rxs; AAR = 388 Rxs per 100,000 beneficiaries). Longitudinal antibiotic prescribing trends were stable among all dental specialties in the regression models (P > .05). The authors observed substantial seasonal variation in antibiotic Rxs in 2 specialties: pediatric dentistry (PTTR, 1.18; 95% confidence interval, 1.13 to 1.25) and orthodontics and dentofacial orthopedics (PTTR, 1.41; 95% confidence interval, 1.21 to 1.71), with the highest rates of antibiotic Rxs in the spring and winter.

CONCLUSIONS

Antibiotic prescribing practices for dental specialists remained stable. The authors observed seasonal trends in 2 specialties.

PRACTICAL IMPLICATIONS

Public health efforts are needed improve antibiotic prescribing among dental specialties.

Evaluation of Drug Susceptibility of Microorganisms in Odontogenic Inflammations and Dental Surgery Procedures Performed on an Outpatient Basis

Bacterial infections are the most common cause of purulent soft tissue inflammations in the head and neck area. These bacteria are also responsible for the majority of inflammatory complications after third molar removal. The key to success of antibacterial treatment in both cases is the use of an appropriate antibacterial agent. The aim of the study was to evaluate the susceptibility profile of bacteria isolated from material collected from patients with intraoral odontogenic abscesses. The test material consisted of swabs taken from the odontogenic abscesses, after their incision and drainage. Another swab was collected from the lesion area, 10 days after the initial visit. Results were compared with an identical study conducted on a control group of healthy patients, who had undergone third molar removal. Bacteria identified in this study consisted of aerobic and anaerobic strains, both Gram-positive and Gram-negative. According to the EUCAST guidelines, none of the tested antibiotics was recommended for all identified bacteria. The percentage of bacterial strains sensitive to amoxicillin and clavulanic acid was 78.13% and 81.48% in the study and control groups, respectively, whereas, the percentage of those sensitive to clindamycin was 96.43% and 80.00%, respectively. For Gram-negative aerobic bacteria, gentamicin and ciprofloxacin were among medications affecting all cultured species. 100.00% of strains were found to be susceptible to these antibiotics. Statistically significant relationship between the presence of Gram-negative aerobic strains and the occurrence of complications was found. In the case of the most frequently occurring bacteria in the study, amoxicillin with clavulanic acid and clindamycin were shown to be very effective. In cases of severe purulent odontogenic inflammations, it is recommended to use a combination of antibiotics. Amoxicillin with ciprofloxacin and clindamycin with cefuroxime seem to be the proper choices based on the results of this study.

A survey of prescribing practices by general dentists in Australia

BACKGROUND

Numerous studies of dental antibiotic prescribing show that overprescribing is a worldwide occurrence. The aim of this study was to assess prescribing practices of general dentists in Australia for antibiotics, analgesics and anxiolytics and to determine the extent to which prescribing is in accordance with current guidelines.

METHODS

A structured questionnaire was sent to 1468 dentists in Victoria and Queensland in July-August 2018. The questionnaire covered demographics, clinical conditions where dentists prescribe antibiotics, non-clinical factors which influence prescribing, and medicines for anxiolysis and pain relief. Responses were scored using a system based on the current Australian therapeutic guidelines. Logistic regression was used to determine the relative importance of independent variables on inappropriate prescribing.

RESULTS

Three hundred eighty-two responses were received. Overall, 55% of overprescribing of antibiotics was detected, with a range of 13-88% on a routine or occasional basis depending on the scenario. Between 16 and 27% of respondents inappropriately preferenced analgesics over anti-inflammatories for dental pain; 46% of those who prescribed anxiolytic medicines did so inappropriately, with varying regimens and choices outside the guidelines. Years of practice was the main demographic factor influencing prescribing, with recent graduates (0-5 years) generally scoring better than their colleagues for antibiotic prescribing (p < 0.05).

CONCLUSIONS

Future interventions could be directed towards the appropriate role and use of antibiotics, shortfalls in knowledge and appropriate choices of medicines for pain relief and anxiolysis. Given that the most overprescribing occurred for localised swellings (88%), this area could be focused on in continuing education as well as ensuring it is addressed in undergraduate teaching. Continuing education on the appropriate use of medicines can be targeted at more experienced dentists as well as patients, especially those who expect antibiotics instead of treatment.

Perceptions, attitudes and factors that influence prescribing by general dentists in Australia: A qualitative study

BACKGROUND

Longitudinal studies of dental prescribing in Australia show that dentists make some inappropriate prescribing choices; literature has shown that dentists tend to overprescribe antibiotics and prescribe for incorrect indications. The unnecessary use of antibiotics is a contributing factor towards the development of antibiotic resistance. The aims of the study were to obtain a greater understanding of the perceptions, attitudes and factors that influence dental prescribing for all major relevant drug classes.

METHOD

Semi-structured interviews of 15 purposively sampled dentists practising in Victoria, Australia were conducted from June-September 2018. Two dentists practised in rural areas and the remainder in urban locations. The range of clinical experience varied from 2.5 to 37 years, with a mean of 13 years. The transcripts were analysed thematically.

RESULTS

Dentists generally preferred amoxicillin as first-line therapy for odontogenic infections, with some confusion about the spectrum and uses of antibiotics. Overprescribing was evident, mostly due to basing judgement for use of antibiotics on symptoms rather than clinical signs. Other factors, such as time pressure, patient expectations, pressure from assistant staff, concern about online criticism and medico-legal considerations, influenced prescribing. Of the dentists who prescribed anxiolytics, most did not have a care protocol for their sedated patients.

CONCLUSION

A variety of prescribing practices were described, and future interventions should target misconceptions around the appropriate use and choice of antibiotics, resources to address the shortfall in knowledge of therapeutics, patient education and staff training, as well as appropriate care and monitoring of sedated patients.

Analysis of essential gene dynamics under antibiotic stress in Streptococcus sanguinis

The paradoxical response of Streptococcus sanguinis to drugs prescribed for dental and clinical practices has complicated treatment guidelines and raised the need for further investigation. We conducted a high throughput study on concomitant transcriptome and proteome dynamics in a time course to assess S. sanguinis behaviour under a sub-inhibitory concentration of ampicillin. Temporal changes at the transcriptome and proteome level were monitored to cover essential genes and proteins over a physiological map of intricate pathways. Our findings revealed that translation was the functional category in S. sanguinis that was most enriched in essential proteins. Moreover, essential proteins in this category demonstrated the greatest conservation across 2774 bacterial proteomes, in comparison to other essential functional categories like cell wall biosynthesis and energy production. In comparison to non-essential proteins, essential proteins were less likely to contain ‘degradation-prone’ amino acids at their N-terminal position, suggesting a longer half-life. Despite the ampicillin-induced stress, the transcriptional up-regulation of amino acid-tRNA synthetases and proteomic elevation of amino acid biosynthesis enzymes favoured the enriched components of essential proteins revealing ‘proteomic signatures’ that can be used to bridge the genotype–phenotype gap of S. sanguinis under ampicillin stress. Furthermore, we identified a significant correlation between the levels of mRNA and protein for essential genes and detected essential protein-enriched pathways differentially regulated through a persistent stress response pattern at late time points. We propose that the current findings will help characterize a bacterial model to study the dynamics of essential genes and proteins under clinically relevant stress conditions.

Part 1. Current prescribing trends of antibiotics by dentists in Australia from 2013 to 2016

BACKGROUND

Literature has shown dentists tend to overprescribe antibiotics and do not always prescribe in accordance with recommended guidelines. Unnecessary prescribing is one major factor that contributes to the development of antibiotic resistance. The aim of the present study was to assess the antibacterial prescribing patterns of dentists in Australia from 2013 to 2016.

METHODS

Data on dental antibacterial prescriptions dispensed under the Pharmaceutical Benefits Scheme (PBS) from 2013 to 2016 was accessed and prescribing trends analysed. The prescribing rates were standardized to the dose and population.

RESULTS

There was a slight decrease in the dispensed use of most antibacterials from 2013 to 2016, but there was a significant increase in the dispensed use of amoxicillin/clavulanic acid of 11.2%. Amoxicillin was the most commonly dispensed antibiotic, accounting for approximately 65% of all antibacterials from 2013 to 2016, while phenoxymethylpenicillin accounted for only 1.4% of prescriptions in 2016. There were low but significant quantities of dispensed antibiotic prescriptions that do not fit with current guidelines.

CONCLUSIONS

The data suggest that dentists in Australia are prescribing some antibiotics inappropriately and there is a preference for moderate- to broad-spectrum agents. The current PBS dental schedule is inconsistent with prescribing guidelines and may contribute to inappropriate prescribing.

Assessment of inappropriate antibiotic prescribing among a large cohort of general dentists in the United States

BACKGROUND

The purpose of this study was to assess dental antibiotic prescribing trends over time, to quantify the number and types of antibiotics dentists prescribe inappropriately, and to estimate the excess health care costs of inappropriate antibiotic prescribing with the use of a large cohort of general dentists in the United States.

METHODS

We used a quasi-Poisson regression model to analyze antibiotic prescriptions trends by general dentists between January 1, 2013, and December 31, 2015, with the use of data from Express Scripts Holding Company, a large pharmacy benefits manager. We evaluated antibiotic duration and appropriateness for general dentists. Appropriateness was evaluated by reviewing the antibiotic prescribed and the duration of the prescription.

RESULTS

Overall, the number and rate of antibiotic prescriptions prescribed by general dentists remained stable in our cohort. During the 3-year study period, approximately 14% of antibiotic prescriptions were deemed inappropriate, based on the antibiotic prescribed, antibiotic treatment duration, or both indicators. The quasi-Poisson regression model, which adjusted for number of beneficiaries covered, revealed a small but statistically significant decrease in the monthly rate of inappropriate antibiotic prescriptions by 0.32% (95% confidence interval, 0.14% to 0.50%; P = .001).

CONCLUSIONS

Overall antibiotic prescribing practices among general dentists in this cohort remained stable over time. The rate of inappropriate antibiotic prescriptions by general dentists decreased slightly over time.

PRACTICAL IMPLICATIONS

From these authors' definition of appropriate antibiotic prescription choice and duration, inappropriate antibiotic prescriptions are common (14% of all antibiotic prescriptions) among general dentists. Further analyses with the use of chart review, administrative data sets, or other approaches are needed to better evaluate antibiotic prescribing practices among dentists.

The effect of interventions aiming to optimise the prescription of antibiotics in dental care-A systematic review

BACKGROUND

Abundant evidence in dentistry suggests that antibiotics are prescribed despite the existence of guidelines aiming to reduce the development of antibiotic resistance. This review investigated (1) which type of interventions aiming to optimise prescription of antibiotics exist in dentistry, (2) the effect of these interventions and (3) the specific strengths and limitations of the studies reporting on these interventions.

METHOD

Literature search was based on Medline, Embase, Global Health, Cochrane CENTRAL, ClinicalTrials.gov and Current Controlled Trials. Studies with one of the two primary outcomes were included: (1) The number of antibiotics prescribed and/or (2) the accuracy of the prescription, commonly measured as a percentage of adherence to local clinical guidelines.

RESULTS

Nine studies met these inclusion criteria. Five studies reported on the prescription of antibiotics in primary dental care and four studies focused on outpatient dental care. Interventions used in primary dental care included a combination of audit, feedback, education, local consensus, dissemination of guidelines and/or academic detailing. Trials in the outpatient setting made use of expert panel discussions, educational feedback on previous acts of prescribing, the dissemination of guidelines and the establishment of internal guidelines. All studies successfully reduced the number of antibiotics prescribed and/or increased the accuracy of the prescription. However, most studies were confounded by a high risk of selection bias, selective outcome reporting and high variance across study groups. In particular, information relating to study design and methodology was insufficient. Only three studies related the prescriptions to the number of patients treated with antibiotics.

CONCLUSIONS

This systematic review was able to offer conclusions which took the limitations of the investigated studies into account. Unfortunately, few studies could be included and many of these studies were confounded by a low quality of scientific reporting and lack of information regarding study methodology. High-quality research with objective and standardised outcome reporting, longer periods of follow-up, rigorous methodology and adequate standard of study reporting is urgently needed.

Trends in antibiotic prescribing by dental practitioners in Germany

PURPOSE

To analyze the structure of antibiotic prescriptions by dentists in Germany during a time-period of four years in relation to medical antibiotic prescriptions.

MATERIALS AND METHODS

We collected nationwide data from all statutory health insurances on dental prescriptions of systemic antibiotics from 2012 to 2015. The annual reports of the "Research Institute for Local Health Care Systems" (WIdO, Berlin) provided the basis for this longitudinal data base analysis. The types of antibiotics, the number of prescriptions and the prescribed 'defined daily doses' (DDD) were analyzed. The results were compared to antibiotic prescriptions of German physicians.

RESULTS

An average of 8.8% per year of all antibiotic prescriptions is issued by dentists. The mostly prescribed antibiotic is amoxicillin. The share of amoxicillin on all dental prescriptions increased from 35.6% in 2012 to 45.8% in 2015 (p < 0.01). About three-quarters of all dentally prescribed DDD can be attributed to amoxicillin and clindamycin. On the part of the physicians the proportion of clindamycin is 18 fold lower than in the dental field.

CONCLUSIONS

Dental and medical antibiotic prescriptions in Germany show statistically significant differences regarding the shares of the prescribed antibiotics. In an international comparison the high proportion of Clindamycin in Germany is noticeable.

Rational use of medicine in dentistry: do dentists prescribe antibiotics in appropriate indications?

PURPOSE

There are concerns regarding appropriate use of antibiotics in dentistry practice. Data on dental antibiotic prescribing patterns by dentists is relatively limited. This nationwide study aimed to examine dentists' antibiotic prescriptions in a diagnosis-based manner in Turkey.

METHODS

This retrospective study on utilization of systemic antibiotics for dental problems was based on the national health data of the dentists obtained from Prescription Information System between January 2013 and August 2015. Only those prescriptions containing single diagnosis and at least one systemic antibiotic were included in the study. Antibiotic prescribing was compared by diagnoses and expertise of dentists.

RESULTS

A total of 9,293,410 antibiotics were detected in 9,214,956 prescriptions that contained "single diagnosis and at least one antibiotic." The number of antibiotics per prescription was 1.01. "Periapical abscess without sinus" (28.1%), "dental examination" (20.7%), and "dental caries" (16.2%) were the three most common indications in which antibiotics were prescribed by dentists. While only 3.4% of antibiotics were prescribed upon the single and appropriate "cellulitis and abscess of mouth" diagnosis, the remaining 96.6% was prescribed for irrational/uncertain indications. Consistent in all diagnoses, "amoxicillin + enzyme inhibitor" (58.6%) was the mainly prescribed antibiotic. Analysis of the most preferred "amoxicillin + enzyme inhibitor" prescriptions by expertise of dentists showed significantly much higher prescription rates among Group A specialists and Group B specialists (67.0 and 67.8%, respectively) than those in unidentified dental practitioners (58.2%, p < 0.0001).

CONCLUSIONS

This study showed that dentists prescribed antibiotics in an arbitrary and mostly unnecessary manner. In general, their antibiotic choices for examined diagnoses could be regarded as irrational. These results indicate the urgent need for improvement of rational antibiotic prescribing habits of dentists.

A survey to assess knowledge, practice, and attitude of dentists in the Western region of Saudi Arabia

Objectives:

To assess knowledge regarding the management of odontogenic infections by dentists in Jeddah, Kingdom of Saudi Arabia.

Methods:

In this cross-sectional study, 150 practitioners responded to a 26-item paper-based questionnaire between August and December 2014. The questionnaire evaluated knowledge and current clinical practices in managing odontogenic infections, as well as the attitude towards antibiotic use and resistance in the community. Basic medical knowledge (BMK) and critical knowledge (CK) scores were calculated from the dentists’ response to these questions and were compared according to educational level (bachelor and postgraduate degree holders).

Results:

The mean BMK score was 1.98 ± 0.4 and CK score was 1.89 ± 0.3. Dentists with bachelor’s degrees had higher BMK scores than those with a postgraduate degree (p=0.005), but CK was not significantly different (p=0.400). Most dentists (77%) would prescribe antibiotics after a routine dental extraction, and would undertake definitive surgical treatment (49.2%) only after a localized space infection developed. Although 82.2% agreed that routine prescription of antibiotics increases bacterial resistance in the community, 71% believe that prescribing an antibiotic after routine oral surgical procedures prevents odontogenic infections.

Conclusion:

Dentists in Jeddah require further education through lectures and workshops to stay up to date on current concepts in odontogenic infection management.

Prescribing patterns of dental practitioners in Australia from 2001 to 2012. Antimicrobials

BACKGROUND

The development of antibiotic resistance by bacteria is of global concern. Inappropriate prescribing has the potential to exacerbate this issue. We aimed to examine the patterns of prescribing of antimicrobial medicines by dental practitioners in Australia from 2001 to 2012.

METHODS

Data were collected from Medicare Australia on prescriptions from dental practitioners dispensed to concessional beneficiaries between 2001 and 2012. We examined patterns of use over time.

RESULTS

There was an overall increase in number of prescriptions and in dispensed use (standardized by dose and population) of antibiotics and antifungals for the concessional population over the 12-year period. The use of dentally prescribed antibiotics increased 50%. Amoxicillin was the most commonly prescribed antibiotic accounting for 66% of all prescriptions in 2012. Generally, there was preferential prescribing of the highest dose formulations. The use of the two antifungals increased 30% over the study period with a preference for amphotericin B (74%) rather than nystatin.

CONCLUSIONS

These data show a concerning increase in prescribing of antibiotics and antifungals by dentists in Australia. It would appear that Australian dentists may not be prescribing these medicines appropriately; however, further research is needed to understand prescribing behaviours and decision-making by dentists.

Antibiotic Prescription Knowledge of Dentists in Kingdom of Saudi Arabia: An Online, Country-wide Survey

AIM

Dentists are probably contributing to the development of bacterial resistance to certain antibiotics. Campaigns to promote prudent use of antibiotics in dentistry are, thus, needed but require proper identification of dentists' knowledge gaps. The objective here was to comprehensively evaluate antibiotic prescription knowledge of dentists in Saudi Arabia.

MATERIAL AND METHODS

A link to an online, previously validated questionnaire was emailed to 5199 dentists registered with the Saudi Dental Society. The questionnaire comprised 42 scorable items measuring antibiotics prescription knowledge in five different domains in addition to nonscorable questions regarding first-choice antibiotics and previous attendance of a course/workshop about antibiotic prescription. Each correct answer was given one mark. Mean scores were calculated as percentages and categorized as good (> 80%), intermediate (60-80%), or poor (< 60%).

RESULTS

The response rate was 9.4%; however, only 373 (7.2%) fully completed the questionnaire. Around half of the participants (52%) reported prescribing amoxicillin/clavulanate as the first-choice antibiotic; 62% reported attending a course/workshop in the last 5 years. The average knowledge score was 69%, being highest for nonclinical indications (79%) and lowest for prophylactic use (56%). The worst per-item scores were noted for rheumatic heart disease (19%), trismus (28%), surgical extraction (30%), apicectomy (31%), and periodontal abscess (33%). Female dentists, dentists in governmental sector, and those with higher qualifications had significantly better knowledge.

CONCLUSION

The level of knowledge was hardly intermediate and several deficits were identified, indicating an urgent need for educational campaigns and provision of guidelines promoting rational use of antibiotics by dentists.

CLINICAL SIGNIFICANCE

Irrational use of antibiotics by dentists can contribute to the problem of antibacterial resistance.

Antibiotic prescribing by dentists has increased: Why?

BACKGROUND

Although the overall rate of antibiotic prescribing has been declining in British Columbia, Canada, the authors conducted a study to explain the increased rate of prescribing by dentists.

METHODS

The authors obtained anonymized, line-listed data on outpatient prescriptions from 1996 to 2013 from a centralized, population-based prescription database, including a variable coding prescriber licensing body. Analyses used Anatomical Therapeutic Classification standard codes and defined daily dose (DDD) values. The authors normalized prescribing rates to the population and expressed the rates in DDDs per 1,000 inhabitants per day (DID). The Canadian Dental Association released a webinar that invited correspondence from dentists about the drivers of the trend.

RESULTS

From 1996 to 2013, overall antibiotic use declined from 18.24 DID to 15.91 DID, and physician prescribing declined 18.2%, from 17.25 DID to 14.11 DID. However, dental prescribing increased 62.2%, from 0.98 DID to 1.59 DID, and its proportionate contribution increased from 6.7% to 11.3% of antibiotic prescriptions. The rate of prescribing increased the most for dental patients 60 years or older. Communication from dentists in Canada and the United States identified the following explanatory themes: unnecessary prescriptions for periapical abscess and irreversible pulpitis; increased prescribing associated with dental implants and their complications; slow adoption of guidelines calling for less perioperative antibiotic coverage for patients with valvular heart disease and prosthetic joints; emphasis on cosmetic practices reducing the surgical skill set of average dentists; underinsurance practices driving antibiotics to be a substitute for surgery; the aging population; and more dental registrants per capita.

CONCLUSIONS

Emerging themes for dental prescribing should be explored further in future studies; however, themes already identified may guide priorities in antibiotic stewardship for continuing dental education sessions.

PRACTICAL IMPLICATIONS

Antibiotic prescribing should be reviewed to make sure that we are compliant with guidelines. Most practitioners will find opportunities to prescribe less often and for shorter durations.

Antibiotic prescribing in UK general dental practice: a cross-sectional study

OBJECTIVES

To assess the extent to which antibiotic prescribing in general dental practice conforms to clinical guidelines and to describe factors associated with antibiotic prescription in the absence of spreading infection or systemic involvement.

METHODS

A cross-sectional study of the management of adult patients with acute dental conditions by General Dental Practitioners (GDPs) in Wales, UK. Clinical information on the management of patients was compared to clinical and prescribing guidelines published by the Scottish Dental Clinical Effectiveness Programme and the Faculty of General Dental Practice (UK). Multilevel logistic regression was used to identify patient, practitioner and consultation characteristics predictive of antibiotic prescribing in the absence of infection.

RESULTS

Antibiotics were prescribed to 57.4% of 568 patients. Over half of antibiotics (65.6%) were prescribed in situations where there was no evidence of spreading infection, and 70.6% were used without the provision of an operative intervention. Only 19.0% of antibiotics were prescribed in situations where their use was indicated by clinical guidelines. Factors associated (P < 0.05) with antibiotic prescription in the absence of infection were failure of previous operative treatment (Odds Ratio (OR) 13.57), shortage of clinical time to undertake treatment (OR 10.21), patients who were unable or unwilling to accept operative treatment (OR 4.89), patient requests for antibiotics (OR 3.69) and acute periodontal conditions (OR 3.37).

CONCLUSIONS

A high level of inappropriate antibiotic prescribing was observed amongst the GDPs studied. Features of the healthcare environment, such as clinical time pressures, and patient-related characteristics, such as expectations for antibiotics and refusal of operative treatment, are associated with antibiotic prescribing in the absence of infection. Individuals responsible for the commissioning and delivery of dental services should seek to develop targeted interventions addressing these issues in order to ensure optimal antimicrobial stewardship within dentistry.
