Is dental treatment of an infected tooth a risk factor for locally invasive spread of infection?

Oral hygiene prior to cardiac surgery to prevent infections: Randomized clinical trial

CONTEXT

It is not clear if an oral hygiene protocol to control biofilm applied before cardiac surgery can reduce infection rates.

OBJECTIVE

We aim to verify the effectiveness of an oral hygiene protocol in reducing postoperative infections when compared to usual practices, in patients admitted to a cardiology unit, prior to cardiac surgery.

DESIGN, SETTING AND PARTICIPANTS

Randomized, blind, controlled clinical trial, with 107 participants who expected to undergo cardiac surgery, randomized into two groups: Experimental Group (EG) standardized oral hygiene protocol (54) and Control Group (CG), usual practices performed in patients admitted (53).

INTERVENTION

a standardized oral hygiene protocol, 1 day before surgery: professional prophylaxis with a portable ultrasound device, tooth brushing and flossing plus a 0.12% chlorhexidine gluconate solution (0.12% CHX) mouth rinsing. When applicable, removable prostheses cleaning.

PRIMARY OUTCOME

the presence of infection.

RESULTS

The occurrence of postoperative infection was higher in CG = 7 (13.2%) than in EG = 5 (9.3%); but no statistical difference was found between protocols (p = 0.518). The length of stayed from surgery to discharge presented a statistical difference (p = 0.047; RR = 4.9; CI = 1.01-24.33); the percentage of postoperative infection was almost five times higher in those participants who stayed 11 or more days.

CONCLUSION

The standardized oral hygiene protocol with mechanical and chemical cleaning, 1 day before cardiac surgery, was not more effective than the usual practices performed regarding the reduction of postoperative infections. Other interventions regarding oral hygiene procedures before cardiac surgery must be studied to contribute to the reduction of adverse post-surgical events.

Prevalence of apical periodontitis and quality of root canal treatment in an adult Kuwaiti sub-population: a cross-sectional study

Objectives

This cross-sectional study evaluated the prevalence of apical periodontitis (AP) and the technical quality of root canal fillings in an adult Kuwaiti subpopulation using cone-beam computed tomography (CBCT) images.

Materials and Methods

Two experienced examiners analyzed 250 CBCT images obtained from Kuwaiti patients aged 15-65 years who attended government dental specialist clinics between January 2019 and September 2020. The assessment followed the radiographic scoring criteria proposed by De Moor for periapical status and the technical quality of root canal filling. Chi-square and Fisher's exact tests were used for statistical analysis, with significance level set at p < 0.05.

Results

Among the 2,762 examined teeth, 191 (6.91%) exhibited radiographic signs of AP, and 176 (6.37%) had undergone root canal filling. AP prevalence in root canal-treated teeth was 32.38%, with a significant difference between males and females. Most of the endodontically treated teeth exhibited adequate root canal filling (71.5%).

Conclusions

The study demonstrated a comparable prevalence of AP and satisfactory execution of root canal treatment compared to similar studies in different countries.

Brazilian dental consensus on dental management in hematopoietic stem cell transplantation - Part I - pre-HSCT

The oral involvement in the Hematopoietic Stem Cell Transplantation is well described in the literature. The goal of the dental treatment and management of the oral lesions related to the HSCT is to reduce the harm caused by preexisting oral infection or even the worsening of oral acute/chronic GVHD and late effects. The aim of this guideline was to discuss the dental management of patients subjected to HSCT, considering three phases of the HSCT: pre-HSCT, acute phase, and late phase. The literature published from 2010 to 2020 was reviewed in order to identify dental interventions in this patient population. The selected papers were divided into three groups: pre-HSCT, acute and late, and were reviewed by the SBTMO Dental Committee's members. When necessary, an expertise opinion was considered for better translating the guideline recommendations to our population dental characteristics. This manuscript focused on the pre-HSCT dental management. The objective of the pre-HSCT dental management is to identify possible dental situations that can worsening during the acute phase after the HSCT. Each guideline recommendations were made considering the Dentistry Specialties. The clinical consensus on dental management prior to HSCT provides professional health caregivers with clinical setting-specific information to help with the management of dental problems in patients to be subjected to HSCT.

Streptococcus anginosus: a stealthy villain in deep odontogenic abscesses

Odontogenic infections (OIs) occasionally spread to deep facial and neck tissues. Our study aimed to explore the role of Streptococcus anginous group (SAG) in these severe OIs. A retrospective study of patients aged ≥ 18 years who required hospital care for acute OI was conducted. We analysed data of OI microbial samples and recorded findings of SAG and other pathogens. These findings were compared with data regarding patients' prehospital status and variables of infection severity. In total, 290 patients were included in the analyses. The most common (49%) bacterial finding was SAG. Other common findings were Streptococcus viridans and Prevotella species, Parvimonas micra, and Fusobacterium nucleatum. Infection severity variables were strongly associated with SAG occurrence. Treatment in an intensive care unit was significantly more common in patients with SAG than in patients without SAG (p < 0.001). In addition, SAG patients expressed higher levels of C-reactive protein (p = 0.001) and white blood cell counts (p < 0.001), and their hospital stays were longer than those of non-SAG patients (p = 0.001). SAG is a typical finding in severe OIs. Clinical features of SAG-related OIs are more challenging than in other OIs. Early detection of SAG, followed by comprehensive infection care with prompt and careful surgical treatment, is necessary due to the aggressive behaviour of this dangerous pathogen.

A Knowledge and Practice Survey Among Dentists in Saudi Arabia Analysing Myths and Misconceptions in Dentistry and Oral Surgery: What Do Dentists Believe?

Introduction To ensure safe and effective practice, dental practitioners must stay up-to-date with all scientific updates involving their profession. In this regard, many outdated myths and misconceptions may be persistently believed and practiced. This study aimed to examine dental misconceptions circulating among dentists in Saudi Arabia. Methods An electronic survey was administered to Saudi Arabian dental practitioners classified and registered with the Saudi Commission of Health Specialties. It collected their demographics, career and experience details, and responses to 16 questions that targeted different myths. Logistic regression was used to analyze factors associated with their knowledge. Results A total of 519 dentists answered the survey, of which 54% were male with a mean age of 32 ± 9 years and a mean practice of 7 ± 8 years. More than half (57%) practiced general dentistry. In most (69%) of the questions, 40% of the respondents answered incorrectly. The proportion of incorrect answers to some questions reached 62%. Years of teaching, years in practice, and doctor rank had no association with the knowledge score. Conversely, the type of practice and specialty had multiple statistically significant associations (p < 0.05). Conclusion This study shows that many myths, despite being debunked for more than 20 years, are still circulating among Saudi Arabian dentists, including many young dentists. Academic institutions must urgently address these concepts and the science that disproves them; dentists must implement up-to-date, evidence-based knowledge in their practice.

Prognostic determinants in severe odontogenic space infections: a single-center retrospective analysis

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.

The inception of a hospital-based dental emergency department in a precarious region decreases the incidence of severe cellulitis of odontogenic origin

INTRODUCTION

Although most localized odontogenic infections can be managed successfully without complications, some can cause extensive morbidity through the onset of cervicofacial cellulitis. The management of these more severe infections generally requires emergency treatment, including surgical treatment under general anesthesia, and prolonged length of hospital stay.

MATERIAL & METHODS

In this work, we assessed the impact of the provision of a hospital-based dental emergency department on the regional incidence of severe odontogenic cellulitis in a socioeconomically precarious region. Monthly case rates of odontogenic cellulitis treated between January 2010 and December 2019 at the hospital-based dental emergency department of Lille Medical University Hospital were collected.

RESULTS

The mean number of monthly severe odontogenic cellulitis cases treated under general anesthesia was significantly higher before than after the inception of the hospital-based dental emergency service [14.07 (5.83) vs 8.79 (4.42); p<0.0001]. Conversely, the monthly mean number of collected odontogenic cellulitis cases treated under local anesthesia was significantly lower before the emergency service was set up [22.42 (12.73) vs 43.32 (23.41); p<0.0001].

CONCLUSION

The provision of a hospital-based dental emergency department resulted in a decrease in severe dental infections in a region with high indices of socioeconomic precarity, morbidity and mortality. Greater accessibility to dental care allows for the rationalization of care through more precocious and fewer burdensome procedures.

Urgent dental care use in the North East and Cumbria: predicting repeat attendance

Introduction Around one-third of the UK population are 'problem-orientated dental attenders', only seeking care when suffering with dental pain and often on a repeated basis to secondary care. Little is known about attendance in primary care. The aim here was to examine the period prevalence of repeat urgent care attenders and establish predictors of repeat attendance in primary care.

Methods Data on urgent and emergency dental care attendances in primary dental care in the North East and Cumbria were analysed from 2013-2019. Variables included: patient sex; ten-year age band; lower super output area; and Index of Multiple Deprivation. Period prevalence was calculated and data were considered year by year to identify trends in attendances. Analysis was with descriptive statistics and predictors of repeat attendance were identified using logistic regression modelling.

Results Over the six-year period, there were 601,432 attendances for urgent primary dental care, equating to a period prevalence of 2.76% for the geographic population studied. In total, 16.15% of attendances were repeat attendances (period prevalence 0.45%) and predictors included being a woman and residence in deprived and rural areas. All urgent care attendances decreased over the six-year period, with one-off attendances beginning to increase again in 2019, while repeat attendances stabilised.

Conclusion Interventions to encourage regular dental attendances should be targeted at patients from the most deprived and rural areas of the North East and Cumbria; however, a decrease in repeat attendance was noted in these areas.

Predictors of being a repeat attender for urgent and emergency dental care included being a woman and living in the most deprived and rural areas of the North East and Cumbria.

Over a six-year period (2013-2019), the number of one-off urgent and emergency dental care attenders to primary care in the North East and Cumbria decreased before beginning to increase.

Over the same period, the number of repeat urgent and emergency dental care attenders to primary care in the North East and Cumbria decreased before stabilising.

Health status in patients hospitalised for severe odontogenic infections

OBJECTIVE

Previous findings refer to certain predisposing medical conditions that compound the risk of developing severe and potentially lethal acute odontogenic infections (OI). The objective of this study was to clarify this rationale and infection severity in general.

MATERIAL AND METHODS

Records of patients aged ≥18 years requiring hospital care for deep OI were retrospectively investigated. The main outcome variable was need for intensive care unit (ICU) treatment. Additional outcome variable was occurrence of infection complications and/or distant infections. Several parameters describing patients' prior health and recent dental treatment were set as independent variables.

RESULTS

Of the 303 acute OI patients included, 71 patients (23%) required treatment in the ICU, with no significant difference between previously healthy and patients with disease history. OIs originating from teeth in the mandible compared with maxilla had 7.8-fold risk (p = .007) for ICU treatment in binary logistic regression analyses. Elevated levels of infection parameters at hospital admission predicted further ICU stay. Infection complications and/or distant infections occurred in 7.6% of patients, of which septicaemia and pneumonia were the most common. The mortality rate was 0.3%. Infection complications and/or distant infections occurred significantly more often in smokers (p = .001) and in patients with excessive consumption of alcohol or drugs (p = .025), however smoking showed 3.5-folded independent risk for infection complications and/or distant infections (p = .008) in logistic regression.

CONCLUSIONS

Severe OIs often occur in previously healthy patients. Smokers in particular are prone to the most serious OIs.

Correlation Between Clinical Course and Biochemical Analysis in Odontogenic Space Infections

OBJECTIVE

To correlate the clinical course and biochemical analysis in odontogenic space infections.

METHODS

A randomized prospective study was undertaken in 50 patients presenting with infections of odontogenic origin. The data were subjected to statistical analysis to co-relate the values of CRP, WBC count and ESR with the clinical course of odontogenic infections. The statistical analysis was carried out using SPSS Version 17.0 clinical parameters included pain, swelling, mouth opening, dyspnea, dysphagia, hoarseness, body temperature, active discharge, length of hospital stay and number of fascial spaces involved.

RESULTS

There was a significant correlation between all the clinical parameters and biochemical markers preoperatively as well as on various postoperative days.

CONCLUSION

According to the percentage rate of fall, CRP was considered as the best indicator of clinical course/recovery of the patient, followed by WBC count and ESR, respectively.

Antimicrobial prescribing by dentists in Wales, UK: findings of the first cycle of a clinical audit

Objective To describe the findings of the first cycle of a clinical audit of antimicrobial use by general dental practitioners (GDPs).Setting General dental practices in Wales, UK.Subjects and methods Between April 2012 and March 2015, 279 GDPs completed the audit. Anonymous information about patients prescribed antimicrobials was recorded. Clinical information about the presentation and management of patients was compared to clinical guidelines published by the Scottish Dental Clinical Effectiveness Programme (SDCEP).Results During the data collection period, 5,782 antimicrobials were prescribed in clinical encounters with 5,460 patients. Of these 95.3% were antibiotic preparations, 2.7% were antifungal agents, and 0.6% were antivirals. Of all patients prescribed antibiotics, only 37.2% had signs of spreading infection or systemic involvement recorded, and 31.2% received no dental treatment. In total, 79.2% of antibiotic, 69.4% of antifungal, and 57.6% of antiviral preparations met audit standards for dose, frequency, and duration. GDPs identified that failure of previous local measures, patient unwillingness or inability to receive treatment, patient demand, time pressures, and patients' medical history may influence their prescribing behaviours.Conclusions The findings of the audit indicate a need for interventions to support GDPs so that they may make sustainable improvements to their antimicrobial prescribing practices.

An unusual case of a brain abscess arising from an odontogenic infection

A brain abscess that originates from an odontogenic infection, although rare, can at times be difficult to diagnose, especially in the context of pain and trismus. We report a rare case of odontogenic infection as a result of an infected maxillary third molar, causing an infratemporal and temporalis collection, resulting in a brain abscess with concurrent cerebritis. This is a clinical case review documenting an uncommon but potentially fatal complication.

Fungal periapical abscess and the burn patient: A report of two cases of an unreported source for systemic infection

Fungal infections in the intensive care unit are becoming a more common occurrence, especially in the care of the burn patient. Fungal infections in the critically burned patient, who by nature have a heightened inflammatory state and impaired immune response, have been found to carry a profound degree of morbidity and mortality. We present our experience in the care of severe thermal injuries; a series of patients with endodontic fungal infection which, as we found, pose a significant risk for the development of systemic infection and sepsis. Fungal periapical abscesses are a rare and, yet undescribed, potential source of systemic sepsis in the burn intensive care unit.

Dental consultations in UK general practice and antibiotic prescribing rates: a retrospective cohort study

BACKGROUND

The frequency of consulting for dental problems in general medical practice, and antibiotic prescribing associated with these consultations, is poorly described.

AIM

To describe consultation rates and antibiotic use for dental problems in UK general medical practice, and explore factors associated with antibiotic prescribing for dental conditions.

DESIGN AND SETTING

A retrospective cohort study using Clinical Practice Research Datalink, a database of general practice patient records in the UK.

METHOD

All dental consultations between 2004 and 2013 were identified. The main outcome was the prescription of an antibiotic during a dental consultation. Multilevel logistic regression was conducted to examine factors associated with antibiotic prescription.

RESULTS

In all, 288 169 dental consultations were included in the cohort. The average rate of dental consultations was 6.06 consultations per 1000 patient-years. Rates of dental consultation decreased from 6.84 consultations per 1000 patient-years in 2008, to 4.23 consultations per 1000 patient-years in 2013. Consultation rates were higher among females than males and highest in patients aged 20-29 years. An antibiotic was prescribed in 57.1% of consultations. Significant predictors (P<0.001) of antibiotic prescribing included: patient middle age, male sex, and previous consultations for tooth-related problems. Antibiotics were more likely to be prescribed during consultations in December (odds ratio [OR] 1.18, 95% confidence interval [CI] = 1.13 to 1.24, P<0.001, reference month: June) and on a Monday (OR 1.10, 95% CI = 1.07 to 1.13, P<0.001) or a Friday (OR 1.15, 95% CI = 1.12 to 1.18, P<0.001, reference day: Wednesday).

CONCLUSION

Consultation rates for dental problems in UK general practice are relatively low but more than half result in the prescription of an antibiotic. This raises concerns about patient morbidity and contributions to antimicrobial resistance.

General practitioners' attitudes towards the management of dental conditions and use of antibiotics in these consultations: a qualitative study

OBJECTIVES

This study aimed to produce an account of the attitudes of general practitioners (GPs) towards the management of dental conditions in general practice, and sought to explore how GPs use antibiotics in the treatment of dental problems.

DESIGN

Qualitative study employing semistructured telephone interviews and thematic analysis.

PARTICIPANTS

17 purposively sampled GPs working in Wales, of which 9 were male. The median number of years since graduation was 21. Maximum variation sampling techniques were used to ensure participants represented different Rural-Urban localities, worked in communities with varying levels of deprivation, and had differing lengths of practising career.

RESULTS

Most GPs reported regularly managing dental problems, with more socioeconomically deprived patients being particularly prone to consult. Participants recognised that dental problems are not optimally managed in general practice, but had sympathy with patients experiencing dental pain who reported difficulty obtaining an emergency dental consultation. Many GPs considered antibiotics an acceptable first-line treatment for acute dental problems and reported that patients often attended expecting to receive antibiotics. GPs who reported that their usual practice was to prescribe antibiotics were more likely to prioritise patients' immediate needs, whereas clinicians who reported rarely prescribing often did so to encourage patients to consult a dental professional.

CONCLUSIONS

The presentation of patients with dental problems presents challenges to GPs who report concerns about their ability to manage such conditions. Despite this, many reported frequently prescribing antibiotics for patients with dental conditions. This may contribute to both patient morbidity and the emergence of antimicrobial resistance. This research has identified the need for quantitative data on general practice consultations for dental problems and qualitative research exploring patient perspectives on reasons for consulting. The findings of these studies will inform the design of an intervention to support patients in accessing appropriate care when experiencing dental problems.

A review of complications of odontogenic infections

Life-threatening infections of odontogenic or upper airway origin may extend to potential spaces formed by fascial planes of the lower head and upper cervical area. Complications include airway obstruction, mediastinitis, necrotizing fascitis, cavernous sinus thrombosis, sepsis, thoracic empyema, Lemierre's syndrome, cerebral abscess, orbital abscess, and osteomyelitis. The incidence of these "space infections" has been greatly reduced by modern antibiotic therapy. However, serious morbidity and even fatalities continue to occur. This study reviews complications of odontogenic infections. The search done was based on PubMed and Google Scholar, and an extensive published work search was undertaken. Advanced MEDLINE search was performed using the terms "odontogenic infections," "complications," and "risk factors."

Effect of Causative Tooth Extraction on Clinical and Biological Parameters of Odontogenic Infection: A Prospective Clinical Trial

PURPOSE

To prospectively compare changes of body temperature, white blood cell count, fibrinogen, and C-reactive protein between odontogenic infections in which the responsible tooth was removed and odontogenic infections in which the treatment included no extraction.

MATERIALS AND METHODS

The sample was composed of patients admitted to the authors' maxillofacial unit for odontogenic infection from 2010 through 2013. One hundred seventy-nine patients were categorized into an extraction or a non-extraction group based on whether the causative tooth was non-restorable or restorable, respectively. Non-restorable teeth were extracted at admission of the patient. Otherwise, the treatment protocol, including incision of the involved space in conjunction with intravenous antibiotics, was the same for the 2 groups. The parameters were measured and recorded at admission and 2 days later. Data records were statistically analyzed by comparing the change of the parameters studied between the extraction and non-extraction groups. P values less than .05 were regarded as statistically significant.

RESULTS

One hundred seventy-nine patients fulfilled the inclusion criteria and were enrolled in the study. The mean age of the patients was 39.1 years (minimum, 14 yr; maximum, 81 yr; standard deviation, 15.4 yr). One hundred nine patients (60.9%) were male, and 70 (39.1%) were female. Differences in the mean decrease of axillary temperature, white blood cell count, fibrinogven, and C-reactive protein between the 2 groups were 0.178, 2,300, 1.01, and 0.64, respectively. All these differences were statistically significant (P =.02, .001, .001, and .001, respectively). Also, the mean hospital stay in the extraction group was 1.05 days shorter than in the non-extraction group, with the difference being statistically significant (P = .006).

CONCLUSIONS

In odontogenic maxillofacial infections, extraction of the causative tooth is associated with a faster clinical and biological resolution of the infection.

Reporting of dental status from full-arch radiographs: Descriptive analysis and methodological aspects

AIM: To identify standards, how entities of dental status are assessed and reported from full-arch radiographs of adults.

METHODS: A PubMed (Medline) search was performed in November 2011. Literature had to report at least one out of four defined entities using radiographs: number of teeth or implants; caries, fillings or restorations; root-canal fillings and apical health; alveolar bone level. Cohorts included to the study had to be of adult age. Methods of radiographic assessment were noted and checked for the later mode of report in text, tables or diagrams. For comparability, the encountered mode of report was operationalized to a logical expression.

RESULTS: Thirty-seven out of 199 articles were evaluated via full-text review. Only one article reported all four entities. Eight articles reported at the maximum 3 comparable entities. However, comparability is impeded because of the usage of absolute or relative frequency, mean or median values as well as grouping. Furthermore the methods of assessment were different or not described sufficiently. Consequently, established sum scores turned out to be highly questionable, too. The amount of missing data within all studies remained unclear. It is even so remissed to mention supernumerary and aplased teeth as well as the count of third molars.

CONCLUSION: Data about dental findings from radiographs is, if at all possible, only comparable with serious limitations. A standardization of both, assessing and reporting entities of dental status from radiographs is missing and has to be established within a report guideline.

Odontogenic infections: an 8-year epidemiologic analysis in a dental emergency outpatient care unit

OBJECTIVES

The purpose of this investigation was to analyze epidemiological patterns, clinical features and the management of odontogenic infections in patients undergoing treatment in a dental emergency outpatient care unit.

STUDY DESIGN

A retrospective analysis of 58 161 case records of patients presenting to an emergency outpatient unit in Hamburg, Germany between 2000-2007 was performed. From this pool, patients with odontogenic infections were identified using an ICD-10 code, analyzing age, gender, medical co-morbidities, duration of pain, ratio of infiltrates/abscesses, affected teeth, management of infection and administered antibiotics.

RESULTS

Of the 58 161 patients, 5357 (9.2%) were identified as having odontogenic infections, with 2689 (50.2%) inflammatory infiltrates and 2668 (49.8%) abscesses. Mean age was 34.8 ± 16.8 years. As the primary site of odontogenic infection, the most significantly affected teeth were the maxillary and mandibular first molars. Patients in age-group 20-29 years (25.1%) utilized the emergency care unit more frequently than other age groups. Clindamycin was the most frequently administered antibiotic.

CONCLUSIONS

Early recognition, diagnosis and management of odontogenic infections are requisite for avoiding or minimizing the development of potential complications. Strategies and evidence-based protocols should be developed within the dental ambulatory care sector, advancing interdisciplinary cooperation between general dentists and oral or maxillofacial surgeons.

[Septic pseudarthrosis of the mandible and endodontic treatment]

INTRODUCTION

Septic pseudarthrosis of the mandible is an uncommon complication with several etiologies. The presence of a tooth next to a fracture site is one of the etiological factors. Conservative management of a tooth in or near the mandibular fracture site is often the issue when treating fracture of a toothed part.

OBSERVATION

A 49 year-old male patient was hospitalized in our department for a bifocal fracture of the mandible (right parasymphysis and left sub-condylar). An open reduction internal fixation with plates and screws was performed. The immediate postoperative period was uneventful except for persistent tooth pain in the parasymphyseal fracture site. At 1 postoperative month, the fracture site was stable and signs of consolidation were documented by the panoramic view. A dentist performed root canal treatment on tooth 42, 8 weeks after surgery, because of recurrent complaint by the patient. At 6 months, clinical and radiological examinations revealed mandibular pseudarthrosis.

DISCUSSION

This type of pseudarthrosis case is relatively infrequent. It occurs after endodontic treatment of a healthy tooth close to the fracture site (performed after the physiological delay before bone healing). The bacterial colonization of the fracture site could be related to this endodontic treatment. This case raises questions on the need for endodontic treatment of a tooth near a mandibular fracture site.
