Computed tomographic anatomy of the mandibular first and second molars and their surrounding structures in the spread of Odontogenic Infection
Oral Radiology, 2009Co-Authors: Aya Ohshima, Yoshiko Ariji, Masakazu Gotoh, Munetaka Naitoh, Kenichi Kurita, Masahiro Izumi, Kazuo Shimozato, Eiichiro ArijiAbstract:Objectives The purposes of this study were to analyze the CT anatomy of the mandibular first and second molars in uninfected subjects and to clarify the pathway of Odontogenic Infection originating from the mandibular first and second molars. Methods CT anatomies, especially for bucco-lingual aspects and the surrounding soft tissues, were investigated in 100 uninfected subjects and 17 infected patients. Results At the level of bifurcation, disappearance of the cortical plates was frequently observed on the buccal and lingual sides of the first molars, and it was reduced on the buccal side in the second molar. In the first molar, the bony width was thinner on the buccal than the lingual side. The lingual cortices were thinner in the second molar. All medial pterygoid and 88% of masseter muscles were situated posteriorly, without horizontally overlapping the second molar, whereas the mylohyoid muscle (MhM) overlapped horizontally with the first and second molars. The MhM was positioned superior to the root apices in 10 and 39% of first and second molars, respectively. All patients with first molar Infection showed involvement of buccal structures, and one showed lingual side involvement. In contrast, six of nine patients with second molar Infection showed involvement on the lingual side. Conclusions Infection originating from the second molar was more likely to spread to the lingual side than Infection originating from the first molar. CT anatomy surrounding the causal teeth supported the spread pathways of mandibular first and second molar Infection.

Odontogenic Infection pathway to the submandibular space imaging assessment
International Journal of Oral and Maxillofacial Surgery, 2002Co-Authors: Yoshiko Ariji, Masakazu Gotoh, Yasuo Kimura, Munetaka Naitoh, Kenichi Kurita, Nagato Natsume, Eiichiro ArijiAbstract:The aims of this study were to determine the pathways of Odontogenic Infection spread into the submandibular space and their relationship to the clinical symptoms. Computerized tomography (CT) and magnetic resonance (MR) images of 33 patients with submandibular involvement were analyzed. The spread of Infection was evaluated by lateral asymmetry of the shape and density of the fascial spaces and tissues, and by obliteration of the interfascial fat spaces. Imaging findings were classified into three types: in 19 patients (57.6%), Infection spread through the mylohyoid muscle or sublingual space (type I). In five patients (15.2%), Infection spread through the bony structures of the mandible with periosteal reaction or perforation of the cortical plate (type II) and was associated with relatively mild symptoms. In four patients (12.1%), Infection spread from the masticatory space (type III). Seven of 11 patients with dysphagia or fever showed submandibular involvement spreading into the parapharyngeal space. CT and MR imaging clearly demonstrated different pathways of the spread of Odontogenic Infection into the submandibular space, which influenced the manifestation of clinical symptoms.

A Case of Odontogenic Infection by Streptococcus constellatus Leading to Systemic Infection in a Cogan’s Syndrome Patient
Case Reports in Dentistry, 2014Co-Authors: Masanobu Abe, Yoshiyuki Mori, Ryoko Inaki, Yae Ohata, Takahiro Abe, Hideto Saijo, Kazumi Ohkubo, Kazuto Hoshi, Tsuyoshi TakatoAbstract:Odontogenic Infection in immunocompromised patients tends to extend systemically beyond the oral cavity. Our case report presents a patient with sepsis due to a Streptococcus constellatus (S. constellatus) Odontogenic Infection in a 64-year-old-immunocompromised woman with Cogan's syndrome. She had been suffering from chronic mandibular osteomyelitis which was thought to have been caused by dental caries and/or chronic periodontitis with furcation involvement of the left mandibular first molar. We suspect that the acute symptoms of the chronic osteomyelitis due to S. constellatus led to the systemic Infection. This Infection could be accelerated by the use of a corticosteroid and an alendronate. This is the first report which represents the potential association between Odontogenic Infection and Cogan's syndrome.

Odontogenic Infection Pathway to the Parapharyngeal Space: CT Imaging Assessment
Journal of Maxillofacial and Oral Surgery, 2020Co-Authors: Ichiro Ogura, Yoshiyuki Minami, Yoshihiro Sugawara, Ryo Mizuhashi, Fumi Mizuhashi, Makoto Oohashi, Hisato SaegusaAbstract: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. 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. 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). 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.

analysis of systemic and local Odontogenic Infection complications requiring hospital care
Journal of Infection, 2008Co-Authors: Lotta Seppanen, Anneli Lauhio, Christian Lindqvist, Riitta Suuronen, Riina RautemaaAbstract:Summary Objective Analysis of systemic and local Odontogenic Infection complications requiring hospital care. Methods All cases of Odontogenic Infections requiring hospital care, which were adjudicated in the Finnish Patient Insurance Centre during 2000–2003, were analysed. Patient characteristics, and the course and outcome of Infection were reviewed. Results The study material consisted of 35 patient cases; 15 male, 20 female; mean age 38.4 (16–67) years. The mean length of hospital stay was 14.8 (2–81) days. Nine patients required intensive care for mean 6.2 (2–19) days. Twenty-five (71%) patients developed local Infection complications with cellulitis and abscess formation, and 10 (29%) patients a generalised or metastatic Infection complication. The length of hospital stay among patients with systemic complications was longer than with local complications, 30.2 (2–81) days vs. 8.0 (2–34) days ( p =0.0144). All patients with local complications survived but three of the 10 patients with systemic complications died. Medically compromised patients with underlying disease developed more often systemic Infection complications than previously healthy patients ( p =0.0028). Conclusions Medically compromised patients appear more susceptible to systemic rather than local Infection complications with a need for significantly longer hospital stay and with an increased risk for fatal complications.

antihemophilic factor is not the only answer for all factor viii deficiencies case report of Odontogenic Infection in a patient with hemophilia a complicated by factor viii inhibitors and managed by transfusion of antihemophilic factor and factor vii
Indian journal of dentistry, 2016Co-Authors: K M Sudheesh, K Siva S N Bharani, H Y Kiran, Suresh HanagavadiAbstract:Dental extraction in hemophiliacs with acquired inhibitors is always a risky procedure, which often presents a lot of problems associated with bleeding. A known case of hemophilia A complicated with factor VIII inhibitors and having Odontogenic Infection was successfully managed by transfusion of factor VIII inhibitor bypass activity (FEIBA) and antihemophilic factor. Past medical history was significant for multiple factor VIII transfusions. Bethesda assay done to identify inhibitors revealed low titer factor VIII inhibitors. Extraction of the involved tooth was done after transfusion of FEIBA with low-dose protocols. Minimal bleeding was noted after extraction which was controlled by local measures. FEIBA was proven to be highly effective, and no side effects of the product were observed.
