Kerr I, Reed D, Brennan AM, Eaton KA. 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. Br Dent J 2021:10.1038/s41415-021-3008-x. [PMID: 34045677 PMCID: PMC8158458 DOI: 10.1038/s41415-021-3008-x] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2020] [Accepted: 08/12/2020] [Indexed: 11/29/2022]
Abstract
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.

Effect of Pulpotomy Procedures With Mineral Trioxide Aggregate and Dexamethasone on Post-endodontic Pain in Patients with Irreversible Pulpitis: A Randomized Clinical Trial. Eur Endod J 2020; 4:69-74. [PMID: 32161890 PMCID: PMC7006548 DOI: 10.14744/eej.2019.91885] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2019] [Accepted: 04/03/2019] [Indexed: 11/24/2022] Open
Abstract
Objective: Endodontic post-treatment pain continues to be one of the main problems encountered by dental professionals. Therefore, pain control during and after endodontic treatment is one of the most important issues in endodontics. The purpose of this clinical trial was to compare postoperative pain relief achieved with dexamethasone (DEX) and mineral trioxide aggregate (MTA) used as pulp coverage after pulpotomy in human molars with irreversible pulpitis. Methods: This prospective double-blind study was conducted on 54 patients complaining of dental pain due to irreversible pulpitis. The standard pulpotomy procedure was performed by the same dentist in all patients. At the time of the cotton pellet placement, patients were randomly divided into three groups: those in whom a sterile dry cotton (DC) pellet was used, patients treated with a cotton pellet soaked in MTA, and those who were treated with a cotton pellet soaked in DEX. After completion of the treatment, patients received rescue medication every 6 hours for the first day. Postoperative pain was assessed at 6-hour intervals for 24 hours, and then every day until day 7 using a visual analog scale. Results: In general, patients treated with MTA suffered the lowest levels of pain at all time intervals. Post-pulpotomy pain was significantly reduced at 18 and 24 hours and from days 2 to 7 post-treatment in the MTA group. DEX lowered the pain level more than the DC pellet. However, the differences observed in the mean pain scores of the DEX and DC pellet groups at all-time intervals were not statistically significant. Conclusion: Pulpotomy procedures can reduce pain related irreversible pulpitis. Pulpotomy with MTA-soaked cotton pellet significantly reduces pain intensity in patients with irreversible pulpitis.

Abstract
BACKGROUND Irreversible pulpitis, which is characterised by acute and intense pain, is one of the most frequent reasons that patients attend for emergency dental care. Apart from removal of the tooth, the customary way of relieving the pain of irreversible pulpitis is by drilling into the tooth, removing the inflamed pulp (nerve) and cleaning the root canal. However, a significant number of dentists continue to prescribe antibiotics to stop the pain of irreversible pulpitis.This review updates the previous version published in 2016. OBJECTIVES To assess the effects of systemic antibiotics for irreversible pulpitis. SEARCH METHODS We searched Cochrane Oral Health's Trials Register (to 18 February 2019); the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 1) in the Cochrane Library (searched 18 February 2019); MEDLINE Ovid (1946 to 18 February 2019); Embase Ovid (1980 to 18 February 2019); US National Institutes of Health Ongoing Trials Register ClinicalTrials.gov (searched 18 February 2019); and the World Health Organization International Clinical Trials Registry Platform (searched 18 February 2019). There were no language restrictions in the searches of the electronic databases. SELECTION CRITERIA Randomised controlled trials which compared pain relief with systemic antibiotics and analgesics, against placebo and analgesics in the acute preoperative phase of irreversible pulpitis. DATA COLLECTION AND ANALYSIS Three review authors screened studies and extracted data independently. We assessed the certainty of the evidence of included studies using GRADE. Pooling of data was not possible and a descriptive summary is presented. MAIN RESULTS No additional trials could be included in this update. One trial at low risk of bias evaluating oral penicillin in combination with analgesics versus placebo with analgesics, involving 40 participants was included in a former update of the review. The certainty of the evidence was rated low for the different outcomes. Our primary outcome was patient-reported pain (intensity/duration) and pain relief. There was a close parallel distribution of the pain ratings in both the intervention (median 6.0, interquartile range (IQR) 10.5), and for placebo (median 6.0, IQR 9.5) over the seven-day study period. There was insufficient evidence to claim or refute a benefit for penicillin for pain intensity. There was no significant difference in the mean total number of ibuprofen tablets over the study period: 9.20 (standard deviation (SD) 6.02) in the penicillin group versus 9.60 (SD 6.34) in the placebo group; mean difference -0.40 (95% confidence interval (CI) -4.23 to 3.43; P = 0.84). This applied equally for the mean total number of Tylenol tablets: 6.90 (SD 6.87) used in the penicillin group versus 4.45 (SD 4.82) in the placebo group; mean difference 2.45 (95% CI -1.23 to 6.13; P = 0.19). Our secondary outcome on reporting of adverse events was not addressed in this study. AUTHORS' CONCLUSIONS This Cochrane Review which was based on one low-powered small sample trial assessed as at low risk of bias, illustrates that there is insufficient evidence to determine whether antibiotics reduce pain or not compared to not having antibiotics. The results of this review confirm the necessity for further larger sample and methodologically sound trials that can provide additional evidence as to whether antibiotics, prescribed in the preoperative phase, can affect treatment outcomes for irreversible pulpitis.

Abstract
BACKGROUND Endodontic treatment of root canals or root canal treatment is a frequently performed dental procedure and is carried out on teeth in which irreversible pulpitis has led to necrosis (death) of the dental pulp (nerve). Removal of the necrotic tissue remnants and cleaning and shaping of the root canal are important phases of root canal treatment. Treatment options include the use of hand and rotary instruments and methods using ultrasonic or sonic equipment. OBJECTIVES The objectives of this review were to determine the relative clinical effectiveness of hand instrumentation versus ultrasonic instrumentation alone or in conjunction with hand instrumentation for orthograde root canal treatment of permanent teeth. SEARCH METHODS We searched the Cochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and LILACS. We searched the reference lists of relevant articles in an attempt to locate additional published and unpublished trials. No language restriction was applied. The last electronic search was conducted in December 2007. SELECTION CRITERIA Randomised controlled trials involving people over 18 years of age with single and multiple permanent teeth with a completely formed apex and with no evidence of internal resorption requiring root canal treatment were included. Patients undertaking re-treatment of a tooth were excluded. DATA COLLECTION AND ANALYSIS Screening of eligible studies was conducted in duplicate and independently. Results were to be expressed as fixed-effect or random-effects models using mean differences for continuous outcomes and risk ratios for dichotomous outcomes with 95% confidence intervals. Heterogeneity was to be investigated including both clinical and methodological factors. MAIN RESULTS No eligible randomised controlled trials were identified. AUTHORS' CONCLUSIONS This review illustrates the current lack of published or ongoing randomised controlled trials and the unavailability of high level evidence, based on clinically relevant outcomes, for the effectiveness of ultrasonic instrumentation used alone or as an adjunct to hand instrumentation for orthograde root canal treatment.Future randomised controlled trials might focus more closely on evaluating the effectiveness of combinations of these interventions with an emphasis on not only clinically relevant but also patient-centred outcomes.

Abstract
BACKGROUND The incidence of endodontic infections is high. The contribution of Endodontics to the global problem of antibiotic resistance could be significant. The ESE, together with the World Health Organization, are promoting the World Antibiotic Awareness Week (13-19 November 2017) to promote the appropriate use of systemic antibiotics in Endodontics. The objective of this study was to determine the prescription pattern of antibiotics in the treatment of endodontic infections of Spanish dentists attending specialization programs in Endodontics. MATERIAL AND METHODS Dentists from five Spanish endodontic postgraduate programs were requested to answer a one-page questionnaire surveying about antibiotics indications. Seventy-three dentists were required to participate in this investigation, and 67 (91.2%) fulfilled satisfactorily the survey and were included in the study. Data were analyzed using descriptive statistics and chi square test. RESULTS The average duration of antibiotic therapy was 6.8±1.2 days. All respondents chose amoxicillin as first choice antibiotic in patients with no medical allergies, alone (40%) or associated to clavulanic acid (60%). The first drug of choice for penicillin allergic patients was clindamycin (72%). For cases of irreversible pulpitis, 22% of respondents prescribed antibiotics. For the scenario of a necrotic pulp, symptomatic apical periodontitis and no swelling, 37% prescribed antibiotics. A quarter of dentists prescribed antibiotics for necrotic pulps with asymptomatic apical periodontitis and a sinus tract. CONCLUSIONS The results of this study show that postgraduate training in Endodontics provides greater awareness of the correct indications of antibiotics. Dentists who have received specialized training in Endodontics have a prescription pattern of antibiotics more adjusted to the guidelines recommended by international organizations and by scientific societies. Key words:Antibiotics, apical periodontitis, dental curriculum, endodontic infections, postgraduate endodontic training.

Abstract
BACKGROUND Bacterial resistance is considered a consequence of misuse or overuse of antibiotics. Dentistry significantly contributes to this increasing public health problem. The aim of this cross-sectional study was to examine the pattern of antibiotics prescribed by Croatian dentists in Zagreb area. METHODS Out of 220 Doctors of Dental Medicine (DMDs) from Zagreb 110 responded to survey. Prior to the research an ethical approval was obtained. Participants were directly contacted. The questionnaire consisted of two parts: general data on DMDs and the part concerning indications, duration, type and dosage of antibiotic therapy. Data were processed using MS Excel and SPSS for Windows, Version 17.0. Statistical significance was tested by Fisher's exact test, chi-square test, Mann-Whitney U test and Spearman's rank correlation at the level of statistical significance p<0.05. RESULTS During the period of two months, the doctors prescribed antibiotics to 1,500 patients, 690 (46%) were men and 810 (54%) women. The most often prescribed antibiotics were penicillin (72.5% of patients), represented mostly by amoxicillin in combination with clavulanic acid (57.6%). The most common indication for the prescribed antibiotics was periapical or periodontal abscess (44%). Definite clinical indication (71.2%) was stated as the most common reason for antibiotic prescription. Antibiotic therapy usually lasted 7 days (62.9%). The doctors prescribed daily doses of antibiotics according to the instructions for the use of specific drugs. CONCLUSION The examined subjects prescribe antibiotics according to the curriculum taught at the School of Dental Medicine for majority of types, doses and duration of the treatments, although antibiotics over-prescription in cases without medical indication was observed. The national guidelines on antibiotic regimens are required in order to reduce unnecessary antibiotic use.

Abstract
OBJECTIVE The use of antimicrobial agents has been increased, leading to bacterial resistance. Therefore the health professionals should have a sound knowledge about the prescription of antibiotics to overcome the increasing bacterial resistance. The main objective of this study was to evaluate the attitudes of dentists towards the prescription of antibiotics during endodontic treatment in north of Saudi Arabia. MATERIALS AND METHODS This was a survey based descriptive cross-sectional study. This study has been done among the dentists of northern region of Saudi Arabia. A questionnaire was designed, regarding pattern of prescription of antibiotics by the dentists in the north of Saudi Arabia and the use of antibiotics in the treatment of different endodontic conditions during endodontic treatment. This questionnaire was distributed among 200 dentists in the north of Saudi Arabia. This study will encourage the dentists of the northern region of Saudi Arabia to be up to date about the current and prospective guidelines for the prescription of antibiotics and follow these guidelines for the antibiotic prescription. RESULTS The collected information was analysed by using a computer software SPSS version 18. Majority of the dentists were male accounting for 86%. The age range for 68% of the respondents was 25-35 years. Most of the dentists were having just a basic dental qualification i.e. 65.60%. Out of the total responding dentists, 50% were working in the ministry of health. 77% of the respondents prescribed the antibiotics for necrotic pulp with acute apical periodontitis; swelling present; mod/ severe preoperative symptoms. Out of the total responding dentists, 45.2% prescribed amoxicillin and clavulanic acid combination as the drug of choice. CONCLUSION It is concluded from the present study that the dentists should know the scientific basis for the prescription of antibiotics during endodontic therapy. They should follow and should not neglect the current guidelines for antibiotic prescriptions. There should be community awareness programmes for the dentists regarding the misuse of antibiotics and antibiotic resistance so that they can play a role in controlling these global problems.

Abstract
BACKGROUND Root canal treatment is carried out on teeth in which irreversible pulpitis has led to necrosis of the dental pulp. As a treatment option it is an alternative to dental extraction. Mechanical preparation and irrigation with antiseptic or antibacterial solutions destroys bacteria and cleans the infected root canal. Irrigants should be effective in deactivating bacteria in the entire root canal space without causing any adverse tissue reactions. Sodium hypochlorite (NaOCl) and chlorhexidine are commonly used but there is uncertainty as to which solution, concentration or combination is the most effective. OBJECTIVES To assess the effects of irrigants used in the non-surgical root canal treatment of mature permanent teeth. SEARCH METHODS We searched the Cochrane Oral Health Group's Trials Register (to 5 July 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2012, Issue 4), MEDLINE via Ovid (1950 to 5 July 2012), EMBASE via Ovid (1980 to 5 July 2012), LILACS via BIREME (1980 to 5 July 2012). There were no restrictions regarding language or date of publication. SELECTION CRITERIA Randomised controlled trials in single or multi-rooted permanent teeth with pulpal or periapical pathology or both, which require root canal treatment. Irrigants either against each other or against inactive irrigant or placebo. Combinations of irrigants were allowed and if used in conjunction with EDTA (ethylenediaminetetra-acetic acid) or similar chelating agents. DATA COLLECTION AND ANALYSIS Two review authors independently assessed risk of bias of included trials and extracted data. MAIN RESULTS We included 11 trials involving 851 participants with 879 teeth which had undergone root canal treatment and involved the use of irrigants. Two trials were assessed as being at low risk of bias, with six unclear and three high. Four trials compared sodium hypochlorite versus chlorhexidine, however, no primary outcomes and only one secondary outcome, bacterial growth cultures, was reported for two of these trials (20% and 50% of teeth in the control group had positive bacterial culture). The meta-analysis indicated no strong evidence of a difference in the existence of bacterial growth between the interventions (risk ratio 0.73; 95% confidence interval 0.34 to 1.56; P = 0.41). The seven remaining trials each compared different interventions and only two of these trials included useable data on the primary outcomes of swelling and pain. One trial compared sodium hypochlorite 5.25% alone versus sodium hypochlorite 5.25% combined with hydrogen peroxide 3%, and versus normal saline and reported pain at 3 to 14 days after the procedure. There was no evidence of a difference in pain between the three groups. The other trial compared sodium hypochlorite 5% versus sodium hypochlorite with 'proteolytic enzyme', and there was no evidence of a difference in swelling between the groups. Two further trials reported bacterial growth, and three trials failed to report any data which could be used in the review. None of the included trials reported any data on adverse effects nor radiological changes in periapical radiolucency. AUTHORS' CONCLUSIONS Although root canal irrigants such as sodium hypochlorite and chlorhexidine appear to be effective at reducing bacterial cultures when compared to saline, most of the studies included in this review failed to adequately report these clinically important and potentially patient-relevant outcomes. There is currently insufficient reliable evidence showing the superiority of any one individual irrigant. The strength and reliability of the supporting evidence was variable and clinicians should be aware that changes in bacterial counts or pain in the early postoperative period may not be accurate indicators of long-term success. Future trials should report both clinician-relevant and patient-preferred outcomes at clearly defined perioperative, as well as long-term, time points.
