Management of odontogenic infection at a district general hospital

Hospitalisations Due to Dental Infection: A Retrospective Clinical Audit from an Australian Public Hospital

The aim of this clinical audit is to evaluate the characteristics of dental infections requiring hospitalisations, which may help improve preventative and management policies. This study retrospectively evaluated the records of patients admitted to the Nepean hospital, Kingswood, New South Wales, Australia, due to dental infections between 2018 and 2019. A total of 102 patients, mostly in their thirties with equal gender distribution, were admitted with dental infections, presenting with pain (100%), swelling (99%), trismus (40.2%), dysphagia (27.4%), fever (21%) [>37 °C], tachycardia (24.8%) and tachypnoea (9.3%). Most patients (68%) presented on weekends, outside regular working hours, and public holidays. A total of 52.5% of patients had taken prior antibiotics. Dental caries, smoking, mental health issues, and illicit drug use were featured strongly. The majority of patients (56.4%) underwent treatment under local anaesthesia. The total length of hospital stay was 271 days (mean 2.7, SD 1.6). Augmentin was the most prescribed antibiotic. Complications were reported in 8.8% of the patients, primarily due to airway compromise. Dental infections leading to hospitalisations continue to be a burden on the healthcare system. A notable finding was that the presentations were primarily on weekends, outside regular working hours, and public holidays, and the majority required dental interventions under local anaesthesia. The provision of on-call emergency dental services may reduce potentially preventable hospitalisations and the length of hospital stay.

The association of travel distance and severity of odontogenic infections

BACKGROUND

Odontogenic infections (OI) are a preventable disease commonly managed in a tertiary hospital setting. Prevention of severe infections and hospitalisation relies on timely access to primary dental care. This study outlines the pre-hospital treatment of patients presenting to hospital with OIs and the association between travel distance from the patients' residence to a tertiary hospital oral and maxillofacial surgical (OMS) unit.

METHODS

This study analysed patients who initially presented hospital with an OI. Patient demographics, pre-hospital treatment, and clinical markers of severity were recorded. The travel distance from the patient's residence to the hospital was recorded in kilometers, along with any inter-hospital transfer via road/air ambulance.

RESULTS

Two hundred twenty-seven patients were included in this study, 17.2% required an inter-hospital transfer. Of these patients, 70.3% had prior treatment before hospitalisation, and antibiotics without source control was the most frequent treatment (83.1%). The mean travel distance for patients with more severe markers of infection significantly greater than patients with minor infections (p = < .001). Patients who required an inter-hospital transfer accounted for most cases with airway compromise requiring ICU admission.

CONCLUSION

This study found that most patients presenting to hospital with an OI had received antibiotics alone as treatment before hospitalisation. The travel distance from a tertiary hospital with OMS services had a significant correlation to more severe infections. This has important public health implications for the allocation of preventative dental services, and patient access to OMS services.

Intra-oral Drainage of Submandibular Abscess: A Minimally Invasive Technique. A Prospective Study

PURPOSE

To evaluate the efficacy of intraoral drainage of isolated submandibular space abscess as a minimally invasive surgical technique compared to the standard trans-cervical approach.

PATIENTS AND METHODS

This prospective study included 40 subjects with isolated submandibular space abscesses. They were randomly divided into 2 equal groups: trans-cervical surgical drainage (group A) and intra-oral surgical drainage (group B). The included data were demographics, repeated surgery requirement, postsurgical hospitalization duration, formation of scar, and complications.

RESULTS

Intraoral drainage (Group B) reduced the mean operative time by 15.25 min (P < 0.001) compared with trans-cervical incision (Group A). No considerable difference was found between the 2 groups in regarding hospitalization postoperatively. No weakness in marginal mandibular nerve was found in both groups. Three patients only have a cervical scar in a group (B) who required external drainage due to recollection. No recurrence was detected in a group (A).

CONCLUSION

The current study demonstrated that isolated submandibular abscesses can be successfully managed with an intraoral drainage modality, and it is a better option than the trans-cervical approach regarding better cosmetic outcome and shorter operative time.

Oral and maxillofacial emergencies: A retrospective study of 5220 cases in West China

BACKGROUND/AIM

There are no epidemiological reports focused on the oral and maxillofacial surgery emergency department in the West China Hospital of Stomatology. The aim of this study was to analyse the epidemiological characteristics of emergency patients admitted for Trauma and Plastic Surgery Department of the West China Hospital of Stomatology from 2016-2019.

MATERIALS AND METHODS

In this retrospective study, 5220 patients with complete medical records were evaluated. The following data were collected: gender, age, etiology, disease type distribution, anatomic injury site and treatment modality.

RESULTS

There were 3046 males and 2174 females (ratio 1.40:1), with an average age of 16.2 years. The largest group was children aged between 3 and 6 years old (28.3%). Maxillofacial injuries were the most common condition (87.3%), which mostly occurred on the forehead (29.7%), followed by the lips (27.8%). A fall was the leading cause of injury (59.9%), especially in patients younger than 6 years old. There were 327 cases of maxillofacial space infections (MSI), and the mandibular third molars were the most common tooth associated with odontogenic infections (36.2%). Univariable analysis identified that multiple-space infection, visit time and systemic conditions were the risk factors for being admitted to the hospital for treatment. There were 116 patients (2.2%) with bleeding as the main complaint, and most of the maxillofacial bleeding patients could be stopped by compression (52.6%).

CONCLUSION

Males and children aged younger than 6 years were the highest risk populations. Trauma accounted for the majority of emergency patients in maxillofacial surgery. Most maxillofacial injuries involved the forehead and were mainly caused by accidental falls. The proportion of MSI was not high, but serious cases may be life-threatening. The causes of bleeding were diverse, and the bleeding was easy to control.

Odontogenic-Related Head and Neck Infections: From Abscess to Mediastinitis: Our Experience, Limits, and Perspectives-A 5-Year Survey

BACKGROUND

Head and neck infections are commonly caused by affections with an odontogenic origin. Untreated or non-responsive to treatment odontogenic infections can cause severe consequences such as localized abscesses, deep neck infections (DNI), and mediastinitis, conditions where emergency procedures such as tracheostomy or cervicotomy could be needed.

METHODS

An epidemiological retrospective observational study was performed, and the objective of the investigation was to present a single-center 5-years retrospective analysis of all patients admitted to the emergency department of the hospital Policlinico Umberto I "Sapienza" with a diagnosis of odontogenic related head and neck infection, observing the epidemiological patterns, the management and the type of surgical procedure adopted to treat the affections.

RESULTS

Over a 5-year period, 376,940 patients entered the emergency room of Policlinico Umberto I, "Sapienza" University of Rome, for a total of 63,632 hospitalizations. A total of 6607 patients were registered with a diagnosis of odontogenic abscess (10.38%), 151 of the patients were hospitalized, 116 of them were surgically treated (76.8%), and 6 of them (3.9%) manifested critical conditions such as sepsis and mediastinitis.

CONCLUSIONS

Even today, despite the improvement of dental health education, dental affections can certainly lead to acute conditions, necessitating immediate surgical intervention.

Epidemiological Analysis and Management of Patients with Facial Space Infections of Odontogenic Origin: A Retrospective Evaluation of Two Years

Objective: Odontogenic infections are one of the most common pathologies in the oral and maxillofacial regions. The spread of odontogenic infections after unsuccessful or late treatment can lead to serious complications. The aim of this study is to examine the epidemiological features and treatment management of patients with odontogenic facial abscesses. Methods: This retrospective study included 88 patients with odontogenic facial area abscesses treated at Afyonkarahisar health sciences university, faculty of dentistry’s maxillofacial surgery clinic between 2019-2021. The socio-demographic, socio-economic characteristics and clinical examination findings of the patients and treatment methods for odontogenic abscess were analyzed comprehensively. Data were evaluated using SPSS-20 and the level of significance was set at p < .05. Results: In the two-year period between 2019 and 2021, 88 patients (44 male and 44 female, mean age was 39.72±16.42) were treated for diffuse facial infections of odontogenic origin. The most commonly involved area was the submandibular area (38.6%), the most affected tooth was mandibular 1st molar and mandibular 3rd molars (18.2%), and the most common cause was dental caries (65.90%). Incision and drainage were performed in half of the patients (36.4% intraoral, 13.6% extraoral). The most commonly used drugs were clindamycin (36.4%), amoxicillin-clavulanate, and ornidazole combination (27.3%). Conclusion: The results of this study confirm that odontogenic abscesses can heal without complications with timely and effective basic interventions such as incision and drainage. In this study, successful results were obtained with the parenteral clindamycin, and a combination of oral amoxicillin-clavulanate and ornidazole in the treatment of odontogenic abscesses.

Antibiotic Therapy in Dentistry

Dental caries, pulpal necrosis, trauma, and periodontal diseases can result in dental infections which could have severe consequences that affect both soft and hard tissues of the oral cavity. Dental infections commonly present with symptoms of pain, fever, and swelling. Surgical and endodontic treatments are the early management of infected teeth, followed by antibiotic therapy. Some alternative methods also exist for treating infection such as low-level laser therapy and photodynamic therapy. Antibiotics are generally used in dental procedures to treat odontogenic infections, nonodontogenic infections, local infection, focal infection, and prophylaxis. Antibiotic prophylaxis is prescribed for patients with immunosuppressed conditions, infective endocarditis, metabolic disorders, and patients with prosthetic joints. To reduce the complications of unnecessary antibiotic prescriptions especially bacterial resistance, comprehensive guidelines should be established. It has been noted that only about 12% of dentists adequately and correctly prescribe antibiotics, which shows the importance of comprehensive guidelines. Antibiotics prescription may result in some adverse effects such as hypersensitivity reactions and dermatological and allergic disorders. Furthermore, unnecessary prescription of antibiotics could result in several serious sequelae, for example, bacterial resistance, gastric and hematological problems, and diversion of bacterial microbiota. The present review attempts to summarize the indications of antibiotic therapy in dentistry and discuss the common types of antibiotics that are routinely used in dental practice based on pharmacologic classes. Moreover, types of antibiotics that are considered safe during pregnancy and childhood are also reviewed.

Maxillofacial space infection experience and risk factors: a retrospective study of 222 cases

BACKGROUND

Maxillofacial space infection (MSI) experience review is beneficial for its management.

AIM

To identify potential risk factors predisposing to the exacerbation of MSI and a prolonged length of stay (LOS).

METHODS

We performed a comprehensive retrospective review of medical records of 222 MSI patients admitted in Center of Stomatology during 1993-2019.

RESULTS

About 63.5% of 222 patients had an odontogenic infection, and submandibular space was the most involved space. Streptococcus spp. was the most common organism isolated (72.4%). Multiple-space cases had more systemic diseases, respiratory difficulty, and life-threatening complications and exhibited worse clinical characteristics (higher white-blood-cell-count, higher body temperature, and restricted mouth opening) than single-space cases (P < 0.05). No significant difference in LOS was found between multiple-space cases and single-space cases. Diabetes and hypertension both accounted for 35.1% in life-threatening cases. Multiple-space infection (60.4%), respiratory difficulty (11.7%), and systemic conditions (43.2%) were identified as critical risk factors associated with life-threatening complications in MSI patients (P < 0.001). A significantly prolonged LOS was found in cases aged ≥ 60 years or with systemic diseases. Community outpatient treatment shortened 1.9 days of LOS compared with self-medication before admission during 2010-2019 (P < 0.05).

CONCLUSION

Comprehensive managements are advisable for MSI patients with multiple-space infection, respiratory difficulty, systemic diseases to avoid disseminated exacerbation, and occurrence of life-threatening complications. Community outpatient treatment was beneficial to a reduced LOS. Timely access to dental outpatient management and simultaneously steady control of diabetes and hypertension was advocated. Improved coverage of insured dental outpatient treatment should be stressed.

Epidemiological analysis of management of severe odontogenic infections before referral to the emergency department

PURPOSE

The aims of the present study are to present the epidemiology and management of patients hospitalized with odontogenic infections in a major Greek hospital from 2015 to 2016 and to find out whether the basic principles of management of odontogenic infections were followed before referral to the emergency department of the Oral and Maxillofacial Surgery Clinic (OMFSED).

METHODS

A retrospective study of the patients hospitalized with odontogenic infections was performed, including management both prior and after referral to the OMFSED.

RESULTS

During the two-year period from 2015 to 2016, 102 patients, 54 men (52.9%) and 48 women (47.1%) were hospitalized with severe odontogenic infections. The most common space involved in severe odontogenic infections was the submandibular (52.9%), and in 31.4% of the patients multiple spaces were involved. The lower third molars were the most common cause (36.5%). In 83 patients (81.4%) the tooth causing the infection had not received any treatment whatsoever and in all cases (100%) no decision for early incision and drainage prior to the referral to the OMFSED was made.

CONCLUSION

The data presented reveal that the basic principles of management of odontogenic infections are not followed before referral of the patients to the OMFSED.

Aerobic and anaerobic microorganisms and antibiotic sensitivity of odontogenic maxillofacial infections

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.
