RESUMO
This case report describes the management of a mandibular first molar with an additional distolingual root (radix entomolaris) and grade III cervical enamel projection through a multidisciplinary approach. Diagnosis for the case was endodontic-periodontal lesion due to non-vitality and associated advanced periodontal destruction. The patient was treated with drainage of the periodontal abscess with adjunct antibiotics, phase I periodontal therapy, endodontic therapy, radiculoplasty, regenerative periodontal therapy, replacement of the missing right mandibular second molar, and long-term maintenance. Follow-up of the patient up to 9 months has been uneventful. Cases of advanced periodontal destruction typically show some degree of tooth mobility, which was absent in this case. The article discusses the tripod effect as well as the increased surface area for periodontal attachment provided by the additional root contributing to the non-mobility of the involved tooth.

BACKGROUND: The aims of the present study were to establish the incidence of head and neck necrotizing fasciitis (NF) in the Adelaide Oral and Maxillofacial Surgery Unit; review the current literature regarding the management of head and neck NF; and determine the evidence for the role of hyperbaric oxygen therapy in the management of NF. METHODS: A retrospective audit of all patients admitted to the Royal Adelaide Hospital Oral and Maxillofacial Surgery Unit 2006-2015 with severe odontogenic infections was carried out. Patient demographics were recorded and treatment details were collected and analysed. RESULTS: A total of 672 patients were admitted for management of severe odontogenic infections. Of these, three were identified as NF. One case was treated using hyperbaric oxygen as an adjunct to conventional surgical and medical management. Two cases were managed using aggressive surgical management alone. Two patients survived. The incidence of head and neck NF in South Australia is 48/100 000 infections per year. CONCLUSIONS: The first-line treatment of severe odontogenic infections remains conventional surgical and medical management; however, hyperbaric oxygen therapy may have an additional role in the management of NF and other rare severe infections in medically complex patients.

IMAGe syndrome (OMIM 300290) is a rare multisystem disorder that has a broad phenotypic presentation. Though variable, this disorder mainly consists of Intrauterine growth retardation, Metaphyseal dysplasia, Adrenal hypoplasia congenita, and Genital abnormalities. Patients with IMAGe syndrome present as an uncommon yet important challenge for dentists and anesthesiologists due to their wide range of dysmorphic facial features, adrenal insufficiency, electrolyte imbalances, and need for steroid replacement. The purpose of this case report is to describe the successful anesthetic management of a pediatric patient diagnosed with IMAGe syndrome who presented for full mouth dental rehabilitation.

This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute disease is under control, definitive treatment should be provided, including appropriate therapy for the pre-existing gingivitis or periodontitis. Among other acute conditions affecting the periodontal tissues, but not caused by the microorganisms present in oral biofilms, infectious diseases, mucocutaneous diseases and traumatic or allergic lesions can be listed. In most cases, the gingival involvement is not severe; however, these conditions are common and may prompt an emergency dental visit. These conditions may have the appearance of an erythematous lesion, which is sometimes erosive. Erosive lesions may be the direct result of trauma or a consequence of the breaking of vesicles and bullae. A proper differential diagnosis is important for adequate management of the case.

Regional odontodysplasia (RO) is an uncommon, nonhereditary, odontogenic developmental disturbance characterized by hypoplasia and hypocalcification of the dental tissues that produce so-called "ghost teeth." This report describes a case of a 2.5-year-old girl who came to the clinic with RO affecting her right maxillary arch. The distinguishing characteristics of this case were the involvement of both the primary and permanent dentitions and the early occurrence of odontogenic abscesses that required the patient's hospitalization. Ultrastructural analysis revealed dental tissue failures that compromised the integrity of the involved teeth, justifying the high susceptibility to caries that was clinically observed. Follow-up was characterized by periodic prosthetic adjustments to maintain the patient's ability to masticate and for social interaction, beyond allowing normal development of her maxillofacial complex. Patients with RO require individualized treatment planning and close follow-up with a multidisciplinary approach.

PURPOSE: Odontogenic infections constitute a substantial portion of diseases encountered by oral and maxillofacial surgeons. Infections start from dental tissues and sometimes rapidly spread to contiguous spaces. The consequence is a fulminant disease with significant morbidity and mortality. The study was aimed at studying the pattern of spread, approach to management, and outcome of these infections at a Nigerian teaching hospital. PATIENTS AND METHODS: A retrospective study of all patients with orofacial infections who presented to our center over an 18-month period was carried out. The medical records were reviewed to retrieve the following: age, gender, source of infection, anatomic fascial spaces involved, associated medical conditions, various treatment modalities, types of antibiotics administered, causative micro-organisms, length of stay in the hospital, and any complications encountered. Infections were classified into 2 categories: those that are confined to the dentoalveolar tissues belong to category I, and those that have spread into the local/regional soft tissue spaces and beyond belong to category II. RESULTS: Odontogenic infections constituted 11.3% of the total oral and maxillofacial surgery cases. A total of 261 patients were treated for odontogenic infections. There were 146 female patients (59.8%) and 98 male patients (40.2%) in the first category, whereas the second category comprised 10 male patients (58.8%) and 7 female patients (41.2%). The fascial spaces involved, in descending order, were submasseteric in 10 (22.7%), submandibular in 9 (20.5%), and sublingual in 6 (13.6%). The causative micro-organisms commonly found were Klebsiella and Streptococcus spp. Incision and drainage were performed in the 17 cases with spreading infection. Amoxicillin, amoxicillin/clavulanate, and metronidazole were the most routinely administered antibiotics. CONCLUSIONS: Our experience shows that delay in presentation, self-medication, aging, male gender, and unusual causative agents are some of the factors associated with spread. Therefore efforts must be made to further improve public dental awareness.

Rubinstein-Taybi syndrome (RTS) occurs in one out of 300,000 individuals. It is mainly characterized by a delay in growth, psychomotor retardation, duplication of the distal phalanx of the thumbs, typical facial dimorphism, a risk of cancer, and multiple dental abnormalities. This case report describes the dental management of a 13-year-old female with RTS, who had multiple dental problems such as caries, periodontal disease, and a severe malocclusion. Physical findings were similar to those previously described in other reports. Dental treatment was carried out under sedation due to the patient's inability to cooperate during dental treatment. After 3 years of follow-up there were no new caries and the periodontal health had improved.

Odontogenic acute mediastinitis is an polymicrobial infections caused in most cases by gram negative and anaerobic germs. The odontogenic origin of the cases in this study was based on anamnestic inquiry of the patients, which reveales a dental treatment 7-15 days before the diagnosis of acute mediastinitis was established. Clinical features are often nonspecific at the debut of this affection; septic shock could appear suddenly associated with multiple systems and organs failure. This is the explication why, some of these patients presented septic shock when are diagnosed. In this situations, when acute mediastinitis is suspected, based on clinical and imaging findings, it must be confirmed by surgical exploration and perioperative bacteriological evaluations. Positive diagnosis is based on clinical features associated with labs and imaging studies. Surgery plays an important role in therapy of acute mediastinitis: debridement and drainage of mediastinum with subsequently lavage of it, using antiseptic solutions. Broad spectrum antibiotherapy should be administrated immediately, before antibiogram is ready.

Traumatic tooth injuries are common in children. When permanent teeth are involved, it can be a challenge to save these teeth. This clinical case study describes the multidisciplinary treatment of a complex crown fracture and luxation of a right maxillary incisor along with esthetic management. After periodontal surgery including guided bone regeneration and endodontic treatment, we used a glass-fibre-reinforced composite post to increase retention and distribute stress along the root. The restoration was completed using composite in an incremental technique. During follow-up appointments, clinical and radiographic examinations revealed no root canal or periodontal problems, suggesting the efficacy of the treatment in retaining the fractured tooth. Periodontal surgery with endodontic treatment is an alternative treatment for severe trauma in permanent teeth.

AIM: To report a clinical case of two advanced periodontal-endodontic lesions with a focus on treatment issues related to tobacco use. SUMMARY: A 53-year-old Caucasian male was referred to the School of Dentistry, Basel, Switzerland, for periodontal treatment. The major diagnoses were chronic (smoker) periodontitis and advanced combined periodontal-endodontic lesions on the mandibular left lateral incisor and right incisor. Conventional root canal treatment was performed, and subsequently led to reduced radiolucencies around the affected roots after 14 months. The remaining osseous defect was augmented by guided tissue regeneration using bovine bone substitute and resorbable membrane. The follow-up revealed a stable situation from clinical (probing depth 2-4 mm) and radiological points of view 32 months after initiation of treatment. Treatment considerations related to tobacco use are discussed. KEY LEARNING POINTS: * After conventional root canal treatment, osseous healing should occur before further complementary therapy is taken into account. * Issues related to tobacco use have to be considered before treatment is initiated.

Mandibular fracture is a rare but possible outcome of a periodontal abscess. A case of complete fracture of the mandible with abscess infiltrating the surrounding soft tissues is described. The patient reported nor trauma, nor locoregional surgery. Ultrasonography and orthopantomography revealed the fracture of the mandible and the abscess at the masseter muscle. Further preoperative diagnostic examinations included CT and MRI. CT revealed the complete fracture line more clearly; MR the extension of the abscess.

The periodontal abscess is an acute destructive process in the periodontium resulting in localized collections of pus communicating with the oral cavity through the gingival sulcus or other periodontal sites and not arising from the tooth pulp. The prevalence of periodontal abscess is relatively high and it affects the prognosis of the tooth. Periodontal abscesses can develop on the base of persisting periodontitis but can also occur in the absence of periodontitis. The cause of the development of periodontal abscess originating from chronic periodontitis is the marginal closure of a periodontal pocket, or the pocket lumen might be too tight to drain the increased suppuration due to changes in the composition of subgingival microflora, alteration of bacterial virulence or host defenses. Diagnosis of a periodontal abscess is based on medical and dental history as well as oral examination (pocket depth, swelling, suppuration, mobility, sensibility of the tooth). The most prevalent group of bacteria: P. gingivalis, P. intermedia, B. forsythus, F. nucleatum and P. micros. Previous studies have suggested that the complete therapy of the periodontitis patients with acute periodontal abscess has to do in two stages: the first stage is the management of acute lesions, then the second stage is the appropriate comprehensive treatment of the original and/or residual lesions. The management of acute lesions includes establishing drainage via pocket lumen, subgingival scaling and root planing, curettage of the lining pocket epithelia and seriously inflamed connective tissue, compressing pocket wall to underlying tooth and periodontal support, and maintaining tissue contact. Some authors recommend the incision or to establish drainage and irrigation, or a flap surgery, or even extraction of hopeless teeth. We recommend the use of systemic antibiotics as a preventive measure of systemic disease or in case of systemic symptoms.

O abscesso periodontal é o terceiro processo infeccioso agudo mais frequente dentre as urgências odontológicas, destruindo rapidamente os tecidos periodontais, podendo interferir no prognóstico do dente envolvido, além de apresentar a possibilidade de disseminação da infecção. Apesar disso, são poucos os trabalhos na literatura que discutem o tratamento dessa lesão. As principais questões permanecem em casos clínicos específicos, nos quais o tratamento dos abscessos pode variar quanto à indicação e o momento da antibioticoterapia sistêmica, e da necessidade do procedimento de drenagem imediata com posterior descontaminação radicular. Logo, o objetivo desta revisão da literatura é estabelecer uma análise crítica sobre as modalidades de tratamento do abscesso periodontal, frente a suas características clínicas e microbiológicas

OBJECTIVES: Recent studies have linked herpesviruses to severe types of periodontal disease, but no information exists on their relationship to periodontal abscesses. The present study determined the presence of human cytomegalovirus (HCMV) and Epstein-Barr virus type 1 (EBV-1) in periodontal abscesses and the effect of treatment on the subgingival occurrence of these viruses. MATERIAL AND METHODS: Eighteen adults with periodontal abscesses participated in the study. Subgingival samples were collected from each patient with sterile curettes from an abscess-affected site and a healthy control site. HCMV and EBV-1 were identified by polymerase chain reaction at the time of the abscess and at 4 months after surgical and systemic doxycycline therapy. RESULTS: HCMV was detected in 66.7% of periodontal abscess sites and in 5.6% of healthy sites (P=0.002). EBV-1 occurred in 72.2% of abscess sites but not in any healthy site (P<0.001). HCMV and EBV-1 co-infection was identified in 55.6% of the abscess sites. Posttreatment, HCMV and EBV-1 were not found in any study site. CONCLUSIONS: HCMV and EBV-1 genomes are commonly found in periodontal abscesses. These data favor a model in which a herpesvirus infection of the periodontium impairs the host defense and serves as a platform for the entrance of bacterial pathogens into gingival tissue with subsequent risk of abscess development.

A seventy-one-year-old woman was hospitalized with a suspicion of deep neck infection and poor general health. She had been receiving treatment for hepatitis, diabetes mellitus, and cardiac failure and had a history of tooth ache and severe neck pain lasting for the past 10 days. She had been admitted to another center where she had received antibiotic treatment for five days for widespread swelling in the neck and lower extremities, fatigue, and difficulty in breathing and swallowing. Upon admission, computed tomography showed gas formation in the neck and facial regions. Prompt abscess drainage was performed and intense treatment with antibiotics was continued. Despite all efforts, the patient died on the second day of hospitalization from cardiopulmonary arrest. This case emphasizes how urgent drainage is when gas formation is detected in deep neck infections, with inevitable poor prognosis with antibiotic treatment alone.

Diabetic ketoacidosis (DKA) is a medical emergency with a potentially fatal outcome if not recognized and treated appropriately. Infective processes are a common precipitant of DKA. We report two cases of dentoalveolar infections in patients with type I diabetes mellitus who presented with DKA. The management of such cases requires both specialist surgical and medical intervention.
