Dou K, Shi Y, Yang B, Zhao Z. Risk factors for life-threatening complications of head and neck space infections: A systematic review and meta-analysis. JOURNAL OF STOMATOLOGY, ORAL AND MAXILLOFACIAL SURGERY 2024:101954. [PMID: 38908479 DOI: 10.1016/j.jormas.2024.101954] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/29/2024] [Revised: 06/17/2024] [Accepted: 06/20/2024] [Indexed: 06/24/2024]
Abstract
OBJECTIVE The present systematic review was performed to identify risk factors associated with life-threatening complications of head and neck space infections (LCHNSI) within the included studies and assess the magnitude of their impact on patients. METHODS We systematically searched PubMed, Web of Science, EmBase, Scopus and CNKI for articles that reported risk factors associated with life-threatening complications of head and neck space infections from inception to 14 December 2023. Only factors reported in at least three papers were considered in the meta-analysis. Pooled odds ratio (OR) and 95 % confidence interval (CI) were calculated using fixed effects model and random effects model. The between-study heterogeneity of effect size was quantified using the Q statistic and I2. In addition, subgroup analysis stratified by study characteristics and sensitivity analysis were performed to explore the potential sources of heterogeneity and the stability of the results. RESULTS The review included a total of 29 studies. The results revealed that the risk factors which associated with LCHNSI were included diabetes mellitus (OR = 3.31, 95 % CI: 2.49-4.40), total leukocyte count(≥15 × 109/L) (OR = 1.21, 95 %CI: 1.04-1.42), multiple space involvement (OR = 4.32, 95 %CI: 3.47-5.38), combined systemic diseases (OR = 9.94, 95 %CI: 6.30-15.67), advanced age(≥60) (OR = 3.90, 95 %CI: 2.80-5.44), dyspnoea (OR = 23.39, 95 %CI: 12.41-44.10), high temperature(≥39°C) (OR = 3.23, 95 %CI: 2.02-5.17), retropharyngeal space involvement (OR = 3.62, 95 %CI: 2.06-6.35), parapharyngeal space involvement (OR = 4.62, 95 %CI: 2.27-9.42). CONCLUSIONS According to the current analysis, diabetes mellitus, total leukocyte count(≥15 × 109/L), combined systemic diseases, multiple space involvement, advanced age(≥60), dyspnoea, high temperature (≥39 °C), retropharyngeal space involvement, parapharyngeal space involvement were the risk factors for LCHNSI. To mitigate the incidence of LCHNSI, clinical staff should carefully manage these risk factors, ensure prompt diagnosis, and implement timely preventive measures.

Abstract
BACKGROUND Despite multiple antibiotics being available to manage dental infections (DI), there is lack of data comparing commonly prescribed antibiotics in India. OBJECTIVES The aim of this study was to evaluate the real-world effectiveness and tolerability of cephalexin-clavulanic acid fixed-dose combination (cephalexin CV FDC) in contrast with amoxicillin-clavulanic acid (co-amoxiclav FDC) and cefuroxime among patients with dental infections (odontogenic) in India. METHODS This retrospective, multi-centric, observational, real-world electronic medical record (EMR)-based study was conducted between January 2022 and December 2022. The EMRs of 355 adults with DI receiving oral cephalexin CV, co-amoxiclav, or cefuroxime were categorized into two distinct groups: Group I (Test Group) with patients prescribed cephalexin extended release 375/750 mg along with clavulanic acid 125 mg; and Group II (Comparator Group) with patients prescribed co-amoxiclav 625 mg (500 mg amoxicillin + 125 mg clavulanic acid) or cefuroxime (250 mg/500 mg). RESULTS Toothache was the most common complaint, reported by 95.5% of patients, followed by swelling (46.8%), tooth sensitivity (35.5%), pus discharge (33.0%), redness and halitosis (30.4% each). Dental caries was observed in 81.1% of patients. Clinical improvement, defined as improvement/partial resolution of infection-related clinical signs and symptoms (composite measure of pain, swelling, fever, requirement of additional antimicrobial therapy) as per dentists' judgment, was recorded in 98.3% of patients with cephalexin CV, 96.8% of patients with co-amoxiclav, and 98.9% of patients treated with cefuroxime within 10 days. Time (days) to clinical improvement was numerically lesser among patients receiving cephalexin CV (4.6 ± 2.0) compared with cefuroxime (4.9 ± 2.1) and co-amoxiclav (5.0 ± 2.6). All treatments were well tolerated. CONCLUSION Cephalexin CV was as effective as co-amoxiclav and cefuroxime, with faster clinical improvement and better resolution of certain symptoms.

[PMID: 37452905 DOI: 10.1007/s40368-023-00824-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/12/2023] [Accepted: 07/08/2023] [Indexed: 07/18/2023]
Abstract
PURPOSE To analyse the epidemiology, treatment, and microbiological findings of hospitalised Lithuanian children and adolescents admitted due to maxillofacial infections over a 17-years period. METHODS 428 medical records of paediatric (under the age of 18) patients hospitalised at Vilnius University Hospital from 2003 to 2019 due to a maxillofacial infection were reviewed. The data concerning patient sociodemographic characteristics, aspects related to a hospital stay, treatment modalities, microbiological findings, and sensitivity to antibiotics, were collected and analysed. RESULTS The most prevalent condition was odontogenic maxillofacial space infection (28.7%), followed by lymphadenitis (21.7%). The mean (sd) age was 10.86 (4.8) years and the male-to-female ratio was 1.37:1. The majority of patients (83.4%) underwent surgical treatment. The mean (sd) hospital stay was 5.49 (2.9) days. The longest hospital stay was observed in the case of odontogenic maxillofacial space infections. A longer period of hospitalisation was generally associated with the presence of anaerobes and their resistance to antibiotics as well as multiple space involvement in deep neck space infections and a permanent causative tooth in odontogenic cases. The most commonly isolated microbiological species was Staphylococcus aureus spp. CONCLUSION The most common origin of maxillofacial infection was odontogenic among investigated Lithuanian children and adolescents. In the majority of cases, a penicillin group antibiotic was prescribed. Streptococci were the predominant bacteria in the cases of odontogenic infection, while Staphylococci were the most prevalent among non-odontogenic cases. Nearly 40.0% of isolated microorganisms were resistant to penicillin. High resistance to metronidazole was identified among anaerobic bacteria.

Abstract
PURPOSES To determine if the empirical use of aminoglycosides is justified in Ludwig's angina based on microscopy, culture and sensitivity results. METHODS A retrospective analysis was done on patients that presented with Ludwig's angina to the Maxillofacial and Oral surgery department at the University of Pretoria. Demographical data was extracted from patient files. Pus specimens that were submitted as part of the initial surgical intervention were analysed. RESULTS Sixty-three patients were included in the study with the majority, 76.19% (n=48/63), comprising males. The mean patient age was 38.6 years (range 6 months to 78 years). The majority of infections (87.3%) had an odontogenic aetiology (n=55/63). Forty-four percent of the patients had immunosuppressive co-morbidities (n=28/63). Streptococci contributed 71.26% (n=62/87) of the cultured bacteria. Similar bacteria were cultured in the immunocompromised and the immunocompetent patients (p=0.672). Ninety-two percent (n=57/62) of the streptococci cultured were sensitive to penicillin. The addition of aminoglycosides to the study sample would not have made a statistically significant difference (p=0.1556). CONCLUSION Based on the findings of this study, the empirical use of aminoglycosides is not warranted in either immunocompromised or immunocompetent patients with Ludwig's angina.

Abstract
PURPOSE This study aimed to evaluate deep odontogenic infection (DOI) spread and features utilizing head and neck computed tomography (CT) imaging. MATERIAL AND METHODS Patients with acute DOI and preoperative contrast-enhanced CT-imaging were included in the study. Infection spaces, radiological features of these infections, CT imaging-based compromised airway and patients' background factors were evaluated and associations between these and need for postoperative mechanical ventilation (MV) were reported. RESULTS Altogether 262 hospitalized patients were included in the final analysis. Typically affected spaces were submandibular (74%), mandibular buccal/vestibular (37%), and sublingual (26%). Retropharyngeal (1%), mediastinal (1%) and danger space (1%) involvements were unusual. The infections were quite evenly distributed between multispace abscesses (53%) and other infections (47%). In multivariate analysis, CT-based compromised airway (OR 5.6, CI 95%, 2.9-10.9, P <0.001), midline crossing (OR 3.3, CI 95%, 1.2-8.8, P = 0.018) and extension at the level or below hyoid body (OR 2.4, CI 95% 1.2-5.1, P = 0.016) predicted the need for MV. Other radiological findings and patients' background variables remained statistically non-significant for MV. CONCLUSION Anterolateral and superior spread to the neck is typical in DOIs, whereas caudal progression is rare. Postoperative need for MV can be well recognized from CT.

Abstract
In our retrospective longitudinal study based on the data from 292 patients, we wanted to investigate whether there was an association between weather conditions and the occurrence of odontogenic abscesses (OA) requiring hospitalization. In the adult group (249 patients), the incidence of severe OA was highest in winter (32.9%) during January (11.6%), with the most common localizations being the perimandibular (35.7%) and submandibular (23.3%) regions. We found that changes in mean daily atmospheric pressure five days before hospitalization showed a positive association with the occurrence of OA, especially pressure variations greater than 12 hPa. Atmospheric pressure changes two and five days before hospitalization were also found to be moderate predictors of complications during treatment. Antibiogram analysis revealed resistance of streptococci to clindamycin in 26.3%. In the pediatric group, OA were also most frequent in winter (30.2%), and the perimandibular region (37.2%) and the canine fossa (20.9%) were the most frequent abscess localizations, while an association with meteorological parameters was not demonstrated. Clinical experience teaches us that weather change influences the occurrence of severe OA requiring hospitalization, which we confirmed in this research. To our knowledge, our study is the first to provide a threshold and precise time frame for atmospheric pressure changes.

Abstract
BACKGROUND Odontogenic space infections are a common presentation in oral and maxillofacial surgery units worldwide. Multiple patient and treatment dependent variables may be used predict the outcomes of the disease process. This study was aimed at a retrospective evaluation of significant predictors of prognosis in terms of length of hospital stay and the need for re-exploration in cases of odontogenic space infections. METHODS Patients who underwent incision and drainage of odontogenic space infections were identified from the hospital records of the Department of Oral and Maxillofacial Surgery, College of Dental Sciences, Davangere, Karnataka, India. The variables assessed included Diabetic status, pyrexia on admission, topical rubefacient agent application, hot fomentation, recent tooth extraction, trismus, dysphagia or dyspnea on presentation, white blood cell count, number of spaces involved, antibiotics used, organisms isolated, severity of the infection and the anesthesia technique used (local anesthesia [LA], conscious sedation or general anesthesia). RESULTS The sample consisted of 259 patients (110 male, 159 female) with a mean age of 41±16.9 years. Space infections were preceded by tooth extractions in 53 (20%) cases, rubefacient balm application in 130 (40%) and hot fomentation in 58 (22%) cases. Trismus was noted in 140 patients with an average mouth opening of 21±10.3 mm. Dyspnea and dysphagia were noted in 55 (21%) and 96 (37%) patients each. Sixty-six patients were diabetic. The average length of hospital stay was 5.8±3 days and re-exploration was required in 75 (29%) patients. Significant predictors of hospital stay were severity (P<0.001), number of spaces affected (P<0.001), hot fomentation (P=0.04), trismus (P<0.001), dysphagia (P<0.001) and dyspnea (P<0.001). Predictors of re-exploration are an increased primary surgery under LA (P<0.001), white blood cell count (P<0.001), rubefacient balm application (P=0.045), dysphagia (P<0.001), dyspnea (P=0.018), and reduced mouth opening (P<0.001). No significant correlation between diabetes and length of hospital stay or the need for re-exploration were found in this study. CONCLUSIONS Poorer outcomes can be predicted based on the severity of the infection, the number of spaces involved, an increased white blood cell count as well as clinical signs and symptoms like trismus, dysphagia and dyspnea. Hot fomentation and Rubefacient agent application were identified as significant determinants of poor prognosis in this study. The presence of these indicators warrants a more aggressive approach towards management of space infections.

Abstract
BACKGROUND It is estimated that up to 90% of head and neck infections have an odontogenic origin, which are considered among the most common in the oral cavity and maxillofacial region. Bacterial resistance has been 1 of the main problems related to the treatment of this type of infection in recent years. The frequency of this resistance is increasing, which is mainly due to patient self-medication and the mutations that bacteria present. Therefore, the objective of this study is to analyze the antimicrobial resistance of antibiotics commonly administered for the treatment of odontogenic infections. METHOD To carry out the study, PubMed, ScienceDirect, and Scopus databases were reviewed using the keywords "odontogenic infection", "pharmacological treatment", and "microbial resistance. Studies whose main objective was the pharmacological treatment of odontogenic infections were selected. Exclusions were review-type studies, systematic reviews, or in vitro or animal model studies. For the analysis of risk of bias, the Checklist for Analytical Cross-Sectional Studies of the Joanna Briggs Institute was used. The search and analysis of the studies was carried out by 2 researchers independently. RESULTS A total of 13 studies were included in this review. The mean age was 39.6 years; the location of the infection in the study subjects was in the submandibular and vestibular spaces; there were periodontal, periapical, and dentoalveolar lesions; the main microorganisms identified were Streptococcus, Staphylococcus, Prevotella, Peptostreptococcus, Clostridium, and Klebsiella; and finally, the main microorganisms identified for bacterial resistance were penicillin, clindamycin and amoxicillin. CONCLUSION The health professional is obliged to update their knowledge to avoid such antibiotic resistance and thus provide better patient care.

Abstract
Odontogenic purulent inflammatory diseases (OPID) make up about 20% of cases in the structure of general surgical pathology and are among the frequent diseases of the maxillofacial region (MFR) with a high (10-40%) mortality rate. Insufficient information about the source state of acute odontogenic inflammation of the peri-mandibular soft tissues significantly reduces the effectiveness of diagnostic measures of OPID in MFR, as evidenced by almost 50% of the diagnostic error rate.
Statistically, OPID in soft-tissue of MFR most often occur due to dissemination of pathogens of the necrotized pulp, periodontal pockets in periodontitis or pericoronitis during the difficult eruption of retained teeth. Previously, the quantitative dominance (about 70%) of Staphylococcus spp. among the microorganisms isolated from the odontogenic foci of inflammation was determined. However, in recent years, with the expansion of microbiological diagnostic capabilities, the presence of non-fermenting Gram-negative bacteria and anaerobes with a significant proportional proportion of the total microbiota of OPID in soft tissue of MFR has been increasingly indicated.
Recently, there has been a rapid acquisition of resistance of pathogens of odontogenic purulent inflammatory diseases of the maxillofacial region to various groups of antibiotics, which leads to ineffectiveness of their treatment and prompts the revision of existing protocols and treatment regimens in surgical dentistry

Abstract
Introduction Parapharyngeal space infection may lead to severe and potentially life-threatening complications. The aim of this study was to assess the odontogenic infection pathway to the parapharyngeal space using CT imaging. Materials and Methods Nineteen patients in mandibular odontogenic infections with abscess who underwent contrast-enhanced CT were evaluated in this study. We reviewed the location of abscess and spread of odontogenic infections to the different components of the buccal space, submandibular space, sublingual space, masticator space and parapharyngeal space using CT imaging. The location of abscess and spread of odontogenic infections were analyzed with the Pearson Chi-square test. Results Regarding the odontogenic infection pathway to parapharyngeal space, the masticator space (100%) was the most frequent, followed by the buccal space (85.7%), submandibular space (85.7%) and sublingual space (57.1%), while those without parapharyngeal space, the submandibular space (83.3%) was the most frequent, followed by the buccal space (75.0%), masticator space (58.3%) and sublingual space (33.3%). The masticator space was significant space in patients with/without parapharyngeal space infection (P = 0.047). Conclusion CT imaging could be an effective method in assessment of odontogenic infection pathway to the parapharyngeal space. The odontogenic infection in masticator space tends to display spread of parapharyngeal space.

[PMID: 35153434 PMCID: PMC8820308 DOI: 10.4103/njms.njms_1_20] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Revised: 06/21/2020] [Accepted: 01/01/2021] [Indexed: 11/10/2022] Open
Abstract
Introduction: Odontogenic infections are mixed aerobic-anaerobic microbial flora. Infections caused by anaerobic bacteria are serious and life-threatening. The microbial specificity in odontogenic infections is technique sensitive depending on the sampling and culturing of specimens. Materials and Methods: A prospective study was carried out on 100 consecutive cases of odontogenic infections treated at our institute over a period of 5 years by surgical intervention and intravenous antibiotics. This study evaluates the pathogenic potential and virulence factors of aerobes and anaerobes as well as its synergistic interrelations with other infectious flora, by culturing of specimens and testing antibiotic sensitivity in standard microbiological methodology in correlation with patient demographic factors. Results: Of the 100 patients of odontogenic space infection, males were more affected, between third and fourth decades. Caries is the most common etiology with involvement of mandibular molars. Submandibular and buccal space is commonly involved. The most common microorganisms isolated being Staphylococcus aureus and Streptococcus viridans are facultative anaerobes which belong to aerobes and Peptostreptococcus predominated among obligate anaerobes. The empirical antibiotic regimen followed is amoxicillin plus clavulanic acid with Metronidazole, followed by surgical treatment. Clindamycin was preferred as the second line of choice in patients resistance to penicillin drugs with comparable efficacy in it. Conclusion: Our study expanded the knowledge base of the microbial flora associated with odontogenic infections, with special reference to anaerobes. Successful management of odontogenic space infection lies in decompression, removal of etiological factors, and also in selecting appropriate antimicrobial therapy depending on microbial flora isolated, for recovery of patients and preventing complications associated with fascial space infection.

Microbiome of Odontogenic Abscesses. Microorganisms 2021; 9:microorganisms9061307. [PMID: 34208451 PMCID: PMC8234849 DOI: 10.3390/microorganisms9061307] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 06/12/2021] [Accepted: 06/14/2021] [Indexed: 11/29/2022] Open
Abstract
Severe odontogenic abscesses are regularly caused by bacteria of the physiological oral microbiome. However, the culture of these bacteria is often prone to errors and sometimes does not result in any bacterial growth. Furthermore, various authors found completely different bacterial spectra in odontogenic abscesses. Experimental 16S rRNA gene next-generation sequencing analysis was used to identify the microbiome of the saliva and the pus in patients with a severe odontogenic infection. The microbiome of the saliva and the pus was determined for 50 patients with a severe odontogenic abscess. Perimandibular and submandibular abscesses were the most commonly observed diseases at 15 (30%) patients each. Polymicrobial infections were observed in 48 (96%) cases, while the picture of a mono-infection only occurred twice (4%). On average, 31.44 (±12.09) bacterial genera were detected in the pus and 41.32 (±9.00) in the saliva. In most cases, a predominantly anaerobic bacterial spectrum was found in the pus, while saliva showed a similar oral microbiome to healthy individuals. In the majority of cases, odontogenic infections are polymicrobial. Our results indicate that these are mainly caused by anaerobic bacterial strains and that aerobic and facultative anaerobe bacteria seem to play a more minor role than previously described by other authors. The 16S rRNA gene analysis detects significantly more bacteria than conventional methods and molecular methods should therefore become a part of routine diagnostics in medical microbiology.

Abstract
PURPOSE Infiltration techniques are used as an adjuvant to regional anesthesia. In this study, we evaluated the efficacy of the superficial cervical plexus nerve block, as an alternative to local infiltration techniques; in the management of mandibular fractures and peri-mandibular space infections. METHODS A prospective randomized controlled trial was conducted on 24 patients having either mandibular fractures or peri-mandibular space infections; and were scheduled for surgery under regional anesthesia (eg, inferior alveolar nerve block, long buccal nerve block). The control group involved delivering a combination of regional anesthesia along with local infiltration. The experimental group received regional anesthesia with a superficial cervical plexus nerve block. The following parameters were studied: pain, onset and duration of anesthesia, time interval until first analgesic request, pulse rate and blood pressure [at different time intervals]. RESULTS Intergroup comparison was done using unpaired t-test. Intragroup comparison was done using repeated measures ANOVA (for >2 observations), followed by a post hoc test. The superficial cervical plexus nerve block group showed highly statistically significant (P < .01) improvement in terms of intra-operative pain at 30 minutes, duration of anesthesia, intraoperative anesthetic requirement, time interval until first analgesic request and intraoperative diastolic blood pressure at 10 minutes. CONCLUSION It can be concluded that the combination of a regional anesthesia technique with a superficial cervical plexus nerve block is an alternative and safe technique for patients undergoing surgery for mandible fractures and perimandibular space infections, with clear advantages over local infiltration.

Faggion PI, Isoton G, Possa E, Tasso L. Is the penetration of clindamycin into the masseter muscle really enough to treat odontogenic infections? Clin Oral Investig 2020; 25:3257-3266. [PMID: 33128135 DOI: 10.1007/s00784-020-03656-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/12/2020] [Accepted: 10/20/2020] [Indexed: 11/25/2022]
Abstract
OBJECTIVES This study aims to determine the penetration of clindamycin into the masseter muscle of rats by microdialysis and correlate with the main microorganisms involved in odontogenic infections. MATERIALS AND METHODS Tissue concentrations of clindamycin in healthy muscle tissue were measured by microdialysis after administration of a single intravenous dose of 51 mg/kg and multiple doses of 17 mg/kg (8/8 h). It was quantified in plasma after a single administration of 51 mg/kg. Microdialysis samples were collected at 30-min intervals and clindamycin was assayed by LC-MS. Pharmacokinetic parameters and tissue penetration were determined. Pharmacokinetic/pharmacodynamic index (ƒ%T > minimum inhibitory concentration (MIC)) was considered to assess dosing regimens. RESULTS The pharmacokinetic parameters determined by non-compartmental plasma analysis for the dose of 51 mg/kg were similar to that determined by compartmental analysis. The maximum free interstitial concentration (Cmax) of clindamycin in muscle tissue was 14.20 (10.63-14.89) and 4.82 (3.35-6.66) mg/L for 51 mg/kg and 17 mg/kg 8/8 h, respectively. In addition, the area under the curve (AUC0-inf) for plasma and tissue of clindamycin were 44.78 (28.82-65.65) and 16.54 (13.83-18.35) h.mg/L for 51 mg/kg, respectively, and the tissue penetration factor determined was 1.10. Considering that the main bacteria that cause odontogenic infections generally present MIC ≤ 0.5 mg/L, the ƒ%T > MIC index is reached when the dose regimen of 17 mg/kg 8/8 h is employed. CONCLUSIONS This investigation showed that clindamycin excellently penetrates muscle tissue of rats. It provides effective antibacterial concentrations at the target site when 17 mg/kg 8/8 h is employed and can be applied to treat the main bacteria causing odontogenic infections. CLINICAL RELEVANCE It reinforces the use of clindamycin in odontogenic infections with significant tissue penetration.

Cefazolin versus ampicillin/sulbactam as an empiric antibiosis in severe odontogenic neck infection descending from the lower jaw-retrospective analysis of 350 cases. Clin Oral Investig 2020; 25:563-570. [PMID: 32779014 DOI: 10.1007/s00784-020-03492-1] [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: 03/20/2020] [Accepted: 08/03/2020] [Indexed: 10/23/2022]
Abstract
OBJECTIVES Odontogenic infections descending from the lower jaw may lead to severe health conditions. Commonly, a biphasic treatment of surgical drainage and antibiotic therapy is conducted. The choice of the administered empiric antibiotic agent remains debatable. MATERIAL AND METHODS Retrospectively, we analyzed 350 medical records of patients who were consecutively treated with odontogenic infections descending from the lower jaw. All patients received surgical drainage and either cefazolin or ampicillin/sulbactam as empiric antibiosis. In particular, the number of secondary operations, infectious parameters, and length of in-hospital stay were investigated. RESULTS The most frequently infected space was the perimandibular/buccal space for both groups followed by the submandibular space. Number of revision procedures, early recurrence, and length of stay presented no significant difference between both groups (p > 0.05). Inflammatory parameters (c-reactive protein, leukocytes) similarly decreased in both groups. CONCLUSION Cefazolin targets the majority of the pathogens detected in severe odontogenic neck infections descending from the lower jaw and reveals comparable results to AMP/S in regard to the inflammatory parameters and in-hospital stay. CLINICAL RELEVANCE Cefazolin is a feasible empiric antibiosis for odontogenic neck infections descending from the lower jaw if surgical drainage is performed.

Abstract
INTRODUCTION Serious abscesses of an odontogenic origin occur frequently in the oral and maxillofacial surgery departments. Rapid surgical incision and drainage constitutes the most important therapeutic action. However, additional surgical therapy and supplementary administration of antibiotics is often carried out, such that the efficiency of this supplementary therapeutic option has been questioned. METHODS All patients with severe odontogenic infections who received surgical treatment under general anaesthesia were recruited to this retrospective study. We determined whether they received additional antibiotic therapy on the ward and if it was possible to improve therapeutic outcomes using this option. RESULTS A total of 258 patients with a severe odontogenic infection between January 2008 and August 2014 were included. The most frequent infection observed was a submandibular abscess (56%), followed by a perimandibular abscess (18%) and a submental abscess (9%). About 65% of the patients were treated with antibiotics in addition to surgery. The median CRP level prior to surgical treatment was 87.8 mg/l (Q1: 40.3 mg/l; Q3: 143.5 mg/l) in patients who were administered an additional antibiotic and 83.8 mg/l (Q1: 37.3 mg/l; Q3: 135.0 mg/l) in those who received no antibiotic treatment after surgery. The postoperative median CRP levels were 116.5 mg/l (Q1: 52.1 mg/l; Q3: 159.3 mg/l) and 106.5 mg/l (Q1: 40.6 mg/l; Q3: 152.6 mg/l), respectively. Neither the preoperative CRP level (p = 0.546) nor the postoperative CRP level (p = 0.450) differed significantly between the groups. But patients who received additional antibiotic therapy had a significantly longer hospital stay (median: 6 days; range: 1-22 days) than patients who had no additional antibiotic therapy (median: 4 days; range: 1-19 days) (p = 0.002). CONCLUSIONS This study did not show an improvement in the therapeutic outcome with administration of supplementary antibiotics in addition to surgery. Thus, surgically incising an abscess is the most important therapeutic action and administration of antibiotics must be critically scrutinised.

Abstract
Hexagonal nanocrystalline powders of the non-doped Ca10(PO4)6(OH)2 as well as activated with Ag+ and Eu3+ ions were synthesized by using different wet chemistry methods. Moreover, the obtained hydroxyapatite was loaded with Ag0, as well as nitroimidazole antimicrobials: metronidazole and tinidazole. The structural properties of the products were analyzed by X-ray diffraction (XRD), scanning (SEM) and transmission (TEM) electron microscopy as well as infrared (IR) and Raman spectroscopy. The photoluminescence properties of the Eu3+ and Ag+ co-doped Ca10(PO4)6(OH)2 were characterized via the PL emission, excitation spectra and the luminescence decay curve. The antimicrobial activity of the obtained materials against Prevotella bivia and Parabacteroides distasonis was studied. The cytotoxicity assessment was carried out on the human osteosarcoma cell line (U2OS) as well as human red blood cells (RBC). The choice of the in vitro model was based on the fact that U2OS is a cancer cell line derived from bone tissue which is rich in apatites that play a pivotal role in the extracellular matrix formation. RBCs are the most abundant blood cells and they are used as a cell model in the study of biocompatibility of new prepared biocompounds with potential medical applications. The obtained multifunctional materials do not exhibit the haemolytic activity, therefore, they could be used as a promising antimicrobial agent and for anaerobic bacteria.

Abstract
Suppurative head and neck infections of odontogenic origin are the most frequent type of head and neck infections. According to the literature, 7-10% of all antibiotics are currently prescribed for their treatment. Since penicillin was invented, the overall antibiotic sensitivity and resistance pattern of the isolated pathogenic microflora has continuously changed. The response of microorganisms to antibiotics and the development of resistance to their action is a purely evolutive process characterized by genetic mutations, acquisition of genetic material or alteration of gene expression and metabolic adaptations. All this makes challenging and difficult the correct choice of empirical antibiotic treatment for head and neck space infections even today. The aim of this paper was to evaluate the literature and to evidence the most frequent locations of odontogenic head and neck infections, the dominant pathogenic microbial flora, the genetic mutations and metabolic changes necessary for bacteria in order to aquire antibiotic resistance and as well its susceptibility and resistance to common antibiotics. We also aimed to highlight the possible changes in bacterial resistance to antibiotics over time, and to assess whether or not there is a need for fundamental changes in the empirical antibiotic treatment of these infections and show which these would be.

Abstract
This study aimed to identify the aerobic and anaerobic causal microorganisms of odontogenic infections and their antibiotic sensitivity. Purulent exudates were taken from patients with odontogenic infections by transdermal puncture, and aerobic and anaerobic microorganisms were identified using biochemical tests. Susceptibility to antibiotics was tested using the Kirby-Bauer method; the inhibition halos were measured according to NCCLS, and based on the results, the microorganisms were classified as susceptible, intermediate or resistant to each antibiotic. Frequencies of species and percentages of resistance were calculated. The microorganisms associated with odontogenic infections were principally anaerobic (65.3% anaerobic vs. 35.7% aerobic), and the susceptibility to antibiotics was higher in anaerobic than in aerobic microorganisms. The majority of isolated microorganisms (82%) showed susceptibility to amoxicillin/clavulanic acid. The causal agents of odontogenic infections were anaerobic microorganisms, which exhibited high resistance to antibiotics.
