Antibiotic prophylaxis dysregulates dental implant placement surgery-induced osteoimmune wound healing and attenuates the alveolar bone-implant interface in mice. J Clin Periodontol 2023; 50:1670-1684. [PMID: 37667415 PMCID: PMC10840745 DOI: 10.1111/jcpe.13875] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 08/12/2023] [Accepted: 08/19/2023] [Indexed: 09/06/2023]
Abstract
AIM Antimicrobial-induced shifts in commensal oral microbiota can dysregulate helper T-cell oral immunity to affect osteoclast-osteoblast actions in alveolar bone. Antibiotic prophylaxis is commonly performed with dental implant placement surgery to prevent post-surgical complications. However, antibiotic prophylaxis effects on osteoimmune processes supporting dental implant osseointegration are unknown. The aim of the study was to discern the impact of antibiotic prophylaxis on dental implant placement surgery-induced osteoimmune wound healing and osseointegration. MATERIALS AND METHODS We performed SHAM or dental implant placement surgery in mice. Groups were administered prophylactic antibiotics (amoxicillin or clindamycin) or vehicle. Gingival bacteriome was assessed via 16S sequencing. Helper T-cell oral immunity was evaluated by flow cytometry. Osteoclasts and osteoblasts were assessed via histomorphometry. Implant osseointegration was evaluated by micro-computed tomography. RESULTS Dental implant placement surgery up-regulated TH 1, TH 2 and TREG cells in cervical lymph nodes (CLNs), which infers helper T-cell oral immunity contributes to dental implant placement osseous wound healing. Prophylactic antibiotics with dental implant placement surgery caused a bacterial dysbiosis, suppressed TH 1, TH 2 and TREG cells in CLNs, reduced osteoclasts and osteoblasts lining peri-implant alveolar bone, and attenuated the alveolar bone-implant interface. CONCLUSIONS Antibiotic prophylaxis dysregulates dental implant placement surgery-induced osteoimmune wound healing and attenuates the alveolar bone-implant interface in mice.

Efficacy and safety of using antibiotics to prevent post-operative complications in oral implant treatment: evidence-based review. BDJ Open 2023; 9:47. [PMID: 37907456 PMCID: PMC10618562 DOI: 10.1038/s41405-023-00174-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 09/25/2023] [Accepted: 09/25/2023] [Indexed: 11/02/2023] Open
Abstract
AIMS To identify and critically appraise available evidence on the efficacy and safety of antibiotics in preventing complications following oral implant placement treatment. METHODS An electronic search was performed using PubMed, Ovid MEDLINE and Cochrane Library databases up to July/21 for the purpose of answering the research question: In[healthy adults treated with dental implants]the use of[different antibiotics before or immediately after treatment]in comparison to[treatment without antibiotics]is safe and effective in terms of[infection, pain, swelling, wound dehiscence, soft tissue healing, early/late implant failure]? Following the Best Evidence Topic methodology, the included studies were categorised based on the Oxford Centre for Evidence-Based Medicine (OCEBM) ratings. The critical appraisal skills programme CASP checklist was used for the methodological analysis. The risk of bias assessment was performed according to the Cochrane Methodology for Systematic Reviews of Interventions. RESULTS 26 of the 245 initially identified articles met our inclusion criteria for analysis after applying rigorous filters. The included human studies demonstrated significant methodological heterogeneity, precluding meta-analysis. These studies spanned evidence levels II to IV, as per OCEBM 2011 classifications, with the United States contributing the most studies (19.2%, n = 5), all at level III. The United Kingdom and Spain followed with three studies each (11.5% each), two from the UK and one from Spain classified at level II. Most studies had less than 1 year of follow-up (21%). Our analysis included 26 studies, with 38 antibiotic patient groups totalling 7459 patients. Amoxicillin was the predominant antibiotic, with various dosage regimens. Complications were observed in studies across different amoxicillin regimens at a cumulative incidence of 5%. CONCLUSION The evidence on antibiotics to prevent implant failure presents uncertain and heterogeneous findings. High-risk bias and underpowered studies were prevalent. Future research should prioritise multicentre, double-blinded RCTs with larger samples and longer follow-ups. Structured methodologies, antibiotic stewardship, and adherence to guidelines are needed. Amoxicillin (2 g) was commonly prescribed, but guidelines recommend 3 g, which results in relatively low complications yet there is limited evidence to support it. Clindamycin was favoured for penicillin allergies, but caution is advised due to potential implant failure risk. Consistent use of antiseptic mouthwash was observed. Future research should explore alternatives to antibiotics and antibiotic stewardship. Establishing a well-funded research consortium could yield conclusive results for clinical practice.

Antibiotics in Dentistry: A Narrative Review of the Evidence beyond the Myth. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2023; 20:6025. [PMID: 37297629 PMCID: PMC10252486 DOI: 10.3390/ijerph20116025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/08/2023] [Revised: 05/18/2023] [Accepted: 05/29/2023] [Indexed: 06/12/2023]
Abstract
Antibiotics have undoubtedly revolutionized medicine and the health and survival of patients with life-threatening infections, being nonetheless free from potential adverse effects, and the risk of intestinal dysbiosis, antimicrobial resistance, and the resulting consequences for the patient's health and the public purse. The present study narratively reviewed the epidemiological data on worldwide antibiotic consumption and administration in dental practice, patients' adherence to prescriptions, the antimicrobial resistance phenomenon in dentistry, and the evidence supporting and recommending appropriate antibiotic use in dental care. Eligible systematic reviews and original studies in humans published in the English language from January 2000 to 26 January 2023 were considered. A total of 78 studies, 47 on the epidemiology of antibiotic use and prescription in dentistry, 6 on antibiotic therapy in dentistry, 12 on antibiotic prophylaxis in dentistry, 0 on adherence of dental patients to antibiotic prescription, and 13 on antimicrobial resistance in dentistry, were presently considered. Retrieved evidence revealed that antibiotics are frequently overused and misused in dental practice, dental patients frequently do not adhere to prescriptions, and antimicrobial resistance in dentistry is a still rising phenomenon also secondary to improper oral antiseptics use. The present findings highlighted the need to establish more evidence-based and accurate antibiotic prescriptions to sensitize dentists and dental patients to minimize and rationalize the use of antibiotics only when it is indicated and necessary, improve patients' adherence, and enhance knowledge and awareness of the antimicrobial resistance in dentistry.

Antimicrobial prescription patterns among oral implantologists of Kerala, India: A cross-sectional survey. J Pharm Bioallied Sci 2022; 14:S712-S718. [PMID: 36110751 PMCID: PMC9469451 DOI: 10.4103/jpbs.jpbs_744_21] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 01/13/2022] [Accepted: 01/24/2022] [Indexed: 11/06/2022] Open
Abstract
Background and Objectives: Antimicrobial resistance is a grave public health concern, and it is important to optimize the use of antimicrobials in dental surgeries. Antimicrobial prescriptions in dental implant placements are often empiric and not guided by consensus or specific guidelines. The aim of this study was to elucidate antibiotic prescribing patterns among oral implantologists. The objectives were to identify the frequency of antimicrobial usage and preferences regarding the perioperative timing of prescriptions, type of antibiotic, dosage, and duration in different implant placement scenarios. Subjects and Methods: An anonymized web-based survey was carried out. Participants were drawn from the lists of oral implantologists from all local branches of the Indian Dental Association in the state of Kerala, India, until the required sample size was met. Responses were recorded using an Internet-based validated questionnaire sent via e-mail to the participants. The questionnaire contained five sections with both open-ended and closed-ended questions. Results: Among the 93 participants, 59% of the dental implantologists preferred 0.2% povidone-iodine as a preprocedural mouth rinse in the backdrop of the COVID-19 pandemic, and 68% prescribed 0.12%–0.2% chlorhexidine as the postoperative mouth rinse. The majority of the participants (73%) routinely prescribed systemic antibiotics perioperatively during implant placement surgery. Interestingly, while none of the participants preferred a solely preoperative regimen, 92.4% of the dentists in our survey prescribed both pre- and postoperative antibiotics. Antibiotics of choice as the preoperative agents were amoxicillin and amoxicillin plus clavulanic acid. The most preferred postoperative agent was amoxicillin plus clavulanic acid. The popularly reported rationale behind a preoperative antibiotic was to decrease or eliminate local or systemic infections (79%), and the majority of the participants (60%) prescribed postoperative antibiotics to prevent postoperative infection. Conclusions: Systemic antibiotic prescriptions in implant placement surgery are not based on currently available evidence. Most oral implantologists who participated in the survey prescribed systemic antibiotics to prevent perioperative infection, even in simple and straightforward implant placements. Specific guidelines need to be generated in complex implant placement situations and implant placement in medically compromised patients to prevent excessive prescriptions.

A questionnaire-based crossover study on the association of microbiological testing with prescription of systemic antibiotics following initial periodontal therapy. J Clin Periodontol 2021; 48:618-626. [PMID: 33751614 DOI: 10.1111/jcpe.13453] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2020] [Revised: 02/23/2021] [Accepted: 02/25/2021] [Indexed: 11/30/2022]
Abstract
AIM (1) To assess prescription of systemic antibiotics following initial periodontal therapy with and without the availability of microbiological information; (2) To identify factors associated with prescription of systemic antibiotics following initial periodontal therapy. MATERIALS AND METHODS Twenty-four clinicians were invited to complete a questionnaire on 20 patient records with respect to periodontal treatment planning, once with microbiological information available and once without. Randomization determined when the microbiological information was provided, and a 3-month washout period was respected between scoring sessions. Regression analysis was performed to identify factors associated with prescription of systemic antibiotics. RESULTS Twenty-one clinicians completed both scoring sessions. Clinicians prescribed systemic antibiotics in on average 56% (95% Confidence Interval (CI) [0.51; 0.61]) of the cases having microbiological information, and in 52% (95% CI [0.47; 0.57]) of the same cases not having that information (p = 0.094). The odds for prescribing systemic antibiotics were 3.34 (95% CI [2.06; 5.42]) times higher when the clinician had at least 3 years of experience, 2.55 (95% CI [1.40; 4.66]) times higher for patients diagnosed with periodontitis stage IV when compared to stage III, 1.08 (95% CI [1.04; 1.11]) times higher for younger patients, 2.78 times (95% CI [1.37; 5.56]) times higher for non-smokers and 2.22 (95% CI [1.27; 3.85]) times higher when less than three teeth would require extraction. No significant associations with the prescription of systemic antibiotics were found for detection of A.actinomycetemcomitans (p = 0.287), grade of periodontitis (p = 0.499) and gender of the patient (p = 0.067). CONCLUSIONS Based on a limited number of cases and clinicians, several patient and clinician related factors were associated with prescription of systemic antibiotics following initial periodontal therapy. However, microbiological testing was not.

Preventive Antibiotic Prescribing Habits among Professionals Dedicated to Oral Implantology: An Observational Study. Antibiotics (Basel) 2021; 10:antibiotics10030301. [PMID: 33799411 PMCID: PMC7999193 DOI: 10.3390/antibiotics10030301] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2021] [Revised: 03/05/2021] [Accepted: 03/12/2021] [Indexed: 12/11/2022] Open
Abstract
The prescription of preventive antibiotics (PA) in oral implantology is a controversial issue. The study aimed to determine the prescribing habits of PA in professionals dedicated to oral implantology in various treatments in healthy and at-risk patients. This is a cross-sectional observational study based on the STROBE (Strengthening the Reporting of Observational Studies in Epidemiology) guidelines. An electronic survey consisting of 4 blocks of questions was sent to members of the Spanish Society of Implants. The data were analyzed using descriptive analysis. A total of 303 participants (20.8%) responded to the questionnaire. One percent never prescribed PA, 55.4% prescribed them always, and 43.6% prescribed them sometimes. Ninety-six percent administered them preoperatively, while 92.4% administered them postoperatively. The most commonly used antibiotic is amoxicillin followed by amoxicillin with clavulanic acid (875/125 mg). Clindamycin is the most commonly administered antibiotic in patients with allergies. Professionals dedicated to oral implantology frequently prescribe PA in both healthy and at-risk patients, especially perioperatively. Immediate implant placement, sinus lifts, bone regeneration, and multiple implant placement are the treatments in which PA are most commonly prescribed, as well as in patients with heart valve prostheses or a history of bacterial endocarditis and immunodeficiency.

Assessment of drug-prescribing perception and practice among dental care providers: a cross-sectional Lebanese study. Pharm Pract (Granada) 2021; 19:2234. [PMID: 33777263 PMCID: PMC7979316 DOI: 10.18549/pharmpract.2021.1.2234] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2020] [Accepted: 02/28/2021] [Indexed: 12/04/2022] Open
Abstract
Background: Dentists play an essential role in providing high-quality dental care, taking
into consideration the clinical context and concomitant medications taken by
the patients. Objective: This study aimed to assess drug-prescribing perception and practices in
addition to drug-related educational needs among Lebanese dentists; it also
evaluated the need for interprofessional collaboration between dentists and
pharmacists. Methods: An exploratory cross-sectional study using an online questionnaire targeted a
sample of dentists from all Lebanese districts. Participants gave their
consent by accepting to complete the survey (ethics approval reference:
USJ-2016-63). The questionnaire consisted of closed-ended questions
exploring: 1) drug-prescribing perception, 2) drug-prescribing practice, and
3) collaboration with pharmacists regarding their respective roles in
providing appropriate counseling to patients. Two indexes were created: the
first evaluated self-confidence in prescribing medications, and the second
assessed dentists’ confidence in pharmacists. Logistic regressions
were performed, taking each index as a dependent variable. Results A total of 137 dentists completed the survey (59% females; mean age:
42.17; SD: 13.78 years). The majority had a fair to good perceived knowledge
in pharmacology and therapeutics (80.3%), only 30.7% reported
to be sufficiently equipped to prescribe safely. Dentists exhibited
particularly low perceived knowledge about prescribing in elderly patients,
dosing, medication use in pregnancy, drug interactions, and adverse
reactions. Dentists specialized in periodontics had the lowest odds of
having self-confidence in prescribing drugs (aOR=0.25; p<0.001).
Also, 64.3% declared that they routinely check a reference source
before prescribing, and 78% relied on pharmaceutical companies and
medical representatives to get information on medications. While 61%
declared that pharmacists should provide oral care counseling, only half of
them encouraged their patients to talk to their pharmacists about their
medications. Only 15% considered that patients are getting enough
counseling from the pharmacist, with a global confidence index below the
median value, suggesting the need for more collaboration, especially with
periodontists who exhibited the lowest confidence in pharmacists
(aOR=0.45). Conclusions Lebanese dentists reported some lack of knowledge and confidence in
prescribing practices. Education, training, and close collaboration between
pharmacists and dentists are essential to overcome these problems and avoid
potential harm to patients.

Prescription of Antibiotic Prophylaxis for Dental Implant Surgery in Healthy Patients: A Systematic Review of Survey-Based Studies. Front Pharmacol 2021; 11:588333. [PMID: 33643035 PMCID: PMC7902906 DOI: 10.3389/fphar.2020.588333] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2020] [Accepted: 11/12/2020] [Indexed: 11/13/2022] Open
Abstract
Background: Systemic antibiotic prophylaxis is frequently prescribed by dentists performing dental implant surgery to avoid premature implant failure and postoperative infections. The scientific literature suggests that a single preoperative dose suffices to reduce the risk of early dental implant failure in healthy patients. Material and Methods: A systematic review was made based on an electronic literature search in the PubMed-Medline, Embase, Web of Science, Scopus and Open Gray databases. The review addressed the question: "which antibiotic prophylaxis regimens are being used in dental implant surgery in healthy patients according to survey-based studies?" The identification, screening, eligibility and inclusion phases were conducted according to the PRISMA statement by two independent reviewers. The following data were collected: country, number of surveyed dentists, number of dentists who responded (n), response rate, routine prescription of antibiotic prophylactic treatment (yes, no, or conditioned prescription), prescription regimen (preoperative, perioperative or postoperative) and antibiotic choice (first and second choice). Cohen's kappa coefficient (k) evaluated the level of agreement between the two reviewers. The analysis of risk of bias was performed follow the Joanna Briggs Institute checklist for observational studies. A descriptive statistical analysis was performed to calculate total target sample, sample size and total mean. Results: A total of 159 articles were identified, of which 12 were included in the analysis. Two thousand and seventy-seven dentists from nine different countries on three continents were surveyed. The median response rate was low and disparate between studies. About three-quarters of the surveyed dentists claimed to routinely prescribe systemic antibiotic prophylaxis for dental implant surgery. The prescription regimen was perioperative, postoperative and preoperative, in decreasing order of frequency. The most frequent first choice drug was amoxicillin, with amoxicillin-clavulanic acid as second choice. Conclusions: A majority of dentists from different countries do not prescribe systemic antibiotic prophylaxis for dental implant surgery following the available scientific evidence and could be overprescribing. Efforts are needed by dental educators and professionals to reduce the gap between the use of antibiotic prophylaxis for dental implant surgery as supported by the scientific evidence and what is being done by clinicians in actual practice.

An Antibacterial Strategy of Mg-Cu Bone Grafting in Infection-Mediated Periodontics. BIOMED RESEARCH INTERNATIONAL 2020; 2020:7289208.

Abstract
Periodontal diseases are mainly the results of infections and inflammation of the gum and bone that surround and support the teeth. In this study, the alveolar bone destruction in periodontitis is hypothesized to be treated with novel Mg-Cu alloy grafts due to their antimicrobial and osteopromotive properties. In order to study this new strategy using Mg-Cu alloy grafts as a periodontal bone substitute, the in vitro degradation and antibacterial performance were examined. The pH variation and Mg2+ and Cu2+ release of Mg-Cu alloy extracts were measured. Porphyromonas gingivalis (P. gingivalis) and Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), two common bacteria associated with periodontal disease, were cultured in Mg-Cu alloy extracts, and bacterial survival rate was evaluated. The changes of bacterial biofilm and its structure were revealed by scanning electron microscopy (SEM) and transmission electronic microscopy (TEM), respectively. The results showed that the Mg-Cu alloy could significantly decrease the survival rates of both P. gingivalis and A. actinomycetemcomitans. Furthermore, the bacterial biofilms were completely destroyed in Mg-Cu alloy extracts, and the bacterial cell membranes were damaged, finally leading to bacterial apoptosis. These results indicate that the Mg-Cu alloy can effectively eliminate periodontal pathogens, and the use of Mg-Cu in periodontal bone grafts has a great potential to prevent infections after periodontal surgery.

Abstract
This study aimed to assess the dosage and types of antibiotics prescribed in oral implant surgery, compare them among the different subpopulations (country and prescription regimens) and against the evidence-based recommended dosage: a 2-gram single preoperative dose of amoxicillin. A meta-analysis of cross-sectional surveys was conducted, which reports the overall dosage (and type) of antibiotics prescribed in combination with implant placement. PubMed, Cochrane, Science, Direct, and EMBASE via OVID were searched until April 2019. Three reviewers independently undertook data extraction and risk of bias assessment. The outcome variable was set on the average of prophylactic antibiotics prescribed per oral implant surgery. Overall, 726 participants from five cross-sectional surveys, representing five different countries were finally included. Amoxicillin was the most prescribed antibiotic. On average, 10,724 mg of antibiotics were prescribed per implant surgery. This average was significantly (p<0.001) higher than 2,000 mg. Overall, amoxicillin doses were significantly higher than 2,000 mg (9,700 mg, p<0.001). All prescribed amoxicillin regimens independently contained more than 2,000 mg, including those comprising only preoperative amoxicillin (2,175 mg, p = 0.006). Exclusive preoperative antibiotic regimens were the only subgroup with prescription dosages below this threshold (p = 0.091). Significant variations in antibiotic prescriptions were found among different countries and antibiotic regimens (p<0.001). In conclusion, the average dose of antibiotics prescribed per oral implant surgery was larger than the evidence-based recommended dose in healthy patients and straightforward conditions. In addition, variations in the average antibiotic dosages were found among different countries and prescription regimens.

Abstract
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.

Abstract
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.

BACKGROUND To describe antibiotic prescribing behaviors in dentistry, including clinical and nonclinical indications for their use, the type and regimen of antibiotics prescribed, and factors influencing their prescription, the authors conducted a scoping review. TYPES OF STUDIES REVIEWED The authors conducted a scoping review of published literature by searching multiple databases. Key search terms included dentist, antibiotic, antimicrobial, antibacterial, prophylaxis, prescription, pattern, habit, knowledge, and practice. Two authors independently reviewed titles and abstracts by using detailed eligibility criteria. The authors placed no restrictions on study design or publication year. The authors qualitatively assessed studies by using a modified version of the Center for Evidence-Based Management's critical appraisal of a survey checklist. RESULTS The authors identified 1,912 studies but considered only 118 studies eligible for review. Most included studies were either cross-sectional surveys (81 studies) or prescription audits (25 studies) from various geographic locations. Publication dates ranged from 1982 through 2017. The authors examined prophylactic and therapeutic antibiotic use in 48 and 29 studies, respectively. Another 29 studies examined the use of both prophylactic and therapeutic antibiotics in dentistry. Overall, dentists prescribed a wide variety of antibiotic regimens for various clinical and nonclinical indications. Dentists have acquired their prescribing knowledge from a variety of sources and have changed their antibiotic prescribing practices throughout their careers for various reasons. CONCLUSIONS AND PRACTICAL IMPLICATIONS Considering the seriousness of antibiotic resistance, the authors highlight trends in antibiotic prescribing practices, characterize factors contributing to the use and misuse of antibiotics in dentistry, provide insight into the importance of antibiotic stewardship in the oral health setting, and encourage dentists to reflect on their antibiotic prescription practices.

Antibiotic prescribing practices in periodontal surgeries with and without bone grafting. J Periodontol 2019; 91:508-515. [PMID: 31398776 DOI: 10.1002/jper.19-0195] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2019] [Revised: 05/05/2019] [Accepted: 05/19/2019] [Indexed: 01/30/2023]
Abstract
BACKGROUND The prevention of postoperative infection is often the basis for antibiotic prescription; however, the risks of unwarranted antibiotics and lack of guidelines for procedures involving bone grafts creates additional difficulty in decision making for practitioners. This study aims to evaluate practices in antibiotics prescribed for periodontal surgeries with and without bone grafting and acceptability of guidelines. METHODS An anonymous survey was distributed to periodontists via the California Society of Periodontists e-mail listserv. The survey questioned prescribing practices for periodontal procedures, prescribing rationale, demographic and dental practice information, and acceptability of guidelines. Results were analyzed using McNemar tests and logistic regression. RESULTS Practitioners were significantly less likely to prescribe antibiotics for traditional periodontal surgeries without bone grafting compared with socket preservation, guided tissue regeneration, guided bone regeneration, and sinus augmentation (P < 0.0001). Practitioners were significantly more likely to prescribe antibiotics with more complex bone grafting such as guided bone regeneration and sinus augmentation compared with socket preservation (P < 0.0001). The most common rationale for prescribing antibiotics with bone grafting was to decrease the chances of developing an infection. Seventy-five percent of practitioners reported they would follow guidelines for antibiotic prescription if they were developed by the American Academy of Periodontology. CONCLUSIONS Practitioners are more likely to prescribe antibiotics with bone grafting and as complexity of the bone grafting procedure increases. Based on these results, the low incidence of infection in periodontal surgery cited in the literature, and willingness of practitioners to adopt guidelines, the establishment of evidence-based guidelines would be of benefit to the periodontal practicing community.

Abstract
BACKGROUND Periodontal disease is a polymicrobial infection characterized by inflammation of the gingiva, alveolar bone resorption and tooth loss. As periodontal disease progresses, oral treponemes (spirochetes) become dominant bacteria in periodontal pockets. Oral treponemes are anaerobes and all encode the enzyme pyruvate-ferredoxin oxidoreductase (PFOR) which catalyzes the oxidative decarboxylation of pyruvate to acetyl-CoA. Here we assess the susceptibility of oral treponemes to amixicile (AMIX), a novel inhibitor of PFOR. METHODS The minimum inhibitory concentration (MIC) of AMIX against several oral treponeme species was determined. The impact of AMIX on processes relevant to virulence including motility, H2 S production, and complement evasion were determined. RESULTS The growth of all oral treponeme species tested was inhibited by AMIX with MIC concentrations (MIC) ranging from 0.5-1.5 μg/mL. AMIX significantly reduced motility, caused a dose-dependent decrease in hydrogen sulfide production and increased sensitivity to killing by human complement (i.e., serum sensitivity). CONCLUSIONS AMIX is effective in vitro in inhibiting growth and other processes central to virulence. AMIX could serve could serve as a new selective therapeutic tool for the treatment of periodontal disease.

Prescription of Antibiotics for Periodontal Disease among Dentists in the Region of Tirana. Open Access Maced J Med Sci 2018; 6:1486-1491. [PMID: 30159082 PMCID: PMC6108801 DOI: 10.3889/oamjms.2018.300] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2018] [Revised: 06/07/2018] [Accepted: 07/04/2018] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND: Periodontal disease has been and will be a challenge for dentists in the entirety of oral pathologies. To date, there is no data regarding the prescription of antibiotics for periodontitis in the district of Tirana. AIM: Evaluate aspects related to the pattern of prescription of antibiotics among dentists in Tirana region for periodontitis. METHODS: Prescriptions from dental practitioners were collected from 25 pharmacies, randomly selected. The only prescription containing a diagnosis of periodontitis, with at least one antibiotic given, was included in the study. Data analysis was done with SPSS 20. RESULTS: Out of 1159 initial prescriptions, only 314 met the selection criteria. The average age of patients was 39.91 ± 15.21 years. Mean duration of therapies was 5.57 ± 1.5 days. The most common form of prescription was one broad-spectrum antibiotic (74.5%), combined antibiotics therapy (22.3%) and narrow-spectrum antibiotic (3.2%). Combined antibiotics involved the use of Metronidazole with Amoxicillin (12.1%) and Metronidazole with Spiramycin (10.2%). Significant differences in the patterns of prescription were identified in relation with patient age and therapy duration (P < 0.05). No statistical difference was found in the patient’s gender and the typology of the therapy (P > 0.05). CONCLUSIONS: Our study shows prescription characteristics of antibiotics for periodontal disease by dentists in Tirana for the first time. Amoxycillin is the most prescribed antibiotic, followed by amoxicillin with clavulanic acid. We found variation in dosage, frequency and duration for all antibiotics used, and perceptible discrepancies between observed and recommended practice. Guidelines on rational antibiotic use are needed for dental practitioners in Tirana and the Republic of Albania for better management of periodontitis and resistance prevention.

Is there a consensus on antibiotic usage for dental implant placement in healthy patients? Aust Dent J 2017; 63:25-33. [PMID: 28543332 DOI: 10.1111/adj.12535] [Citation(s) in RCA: 38] [Impact Index Per Article: 5.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 05/18/2017] [Indexed: 11/30/2022]
Abstract
This systematic review aimed to determine whether there is consensus for antibiotic prescription in healthy patients undergoing implant placement. A search of PubMed, Embase and Medline databases was conducted in January 2016 to find published journal articles on the use of antibiotics in implant placement, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The inclusion criteria were prospective human clinical trials investigating antibiotic usage during implant placement. Fifteen studies were deemed suitable. In 13 studies, no statistical difference was found between antibiotic use and the incidence of prosthetic failure, implant failure and early postoperative infections. These were rated as having low to high risk bias. Contrary results were reported in two studies, both of which were rated as having a high potential for bias. In conclusion, antibiotic use in healthy patients for the prophylaxis of surgical infection associated with dental implant placement does not appear to improve clinical outcomes. Practitioners should apply principles of antimicrobial stewardship and not use antibiotics as a routine measure in healthy patients.

Prospective cohort study of dental implant success rate in patients with AIDS. Int J Implant Dent 2016; 2:20. [PMID: 27747712 PMCID: PMC5040648 DOI: 10.1186/s40729-016-0053-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2016] [Accepted: 07/12/2016] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Oral health care of patients with acquired immune deficiency syndrome (AIDS) due to human immunodeficiency virus (HIV) is a growing area of concern, taking into consideration the increased life expectancy of patients resulting from antiretroviral therapy. There is insufficient literature regarding the impact of dental implants in AIDS patients. This study investigated the long-term clinical outcome of implant placement in patients diagnosed with AIDS. METHODS This monocentric study included AIDS patients with CD4 <200 cells/μL, age 18 years or older, and a minimum of one edentulous space requiring implant. All patients in the study were undergoing highly active antiretroviral therapy (HAART). HAART includes nucleoside reverse transcriptase inhibitors (NRTIs), non-nucleoside reverse transcriptase inhibitors (NNRTIs), protease inhibitors (PIs), and integrase strand transfer inhibitors (INSTIs). Typical treatment includes two different NTRIs, along with a third drug, either an INSTI, a PI, or an NNRTI. Bicon dental implants were placed in the patients after medical clearance and were followed up for 5 years. Bicon system implants were chosen because of availability and previous experience with this brand. Implant success criteria are defined as implants that had no clinical mobility at uncovering, no radiographic radiolucency, and allowed for loading and abutment placement. Implant success in AIDS patients was measured over a period of 5 years. Descriptive statistics were used. RESULTS Sixteen adults met the inclusion criteria (12 males and 4 females) with mean CD4 count as 141.25 (sd 35.5). Thirty-three implants were placed in selected patients. Average time to uncovering was 151 days (sd 25 days). Two of the three failures were maxillary implants in the anterior arch, and the third was in the mandibular posterior arch. CONCLUSIONS The study found a slightly higher failure rate of 10 % in patients with AIDS, compared to widely accepted failure rates in healthy patients at 5-7 %. With the advent of new medical therapies, even AIDS patients should be offered the option of root-formed implants as a viable alternative to fixed and removable prosthetics.
