1/16. Unusual tooth sensation due to maxillary sinusitis--a case report.maxillary sinusitis can cause pain or discomfort to the maxillary dentition but no report of patients complaining of a "jumping tooth sensation" during sinusitis has been recorded in the literature. This article presents a case of an unusual localised sensation from a maxillary right second premolar experienced while undergoing root canal treatment. This sensation was felt during walking while the patient was suffering an episode of influenza. This sensation first occurred following debridement of the root canal. However, it persisted even after the root canal had been sealed. A hypothetical explanation of this manifestation is proposed.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/16. Nonsurgical treatment for odontogenic maxillary sinusitis using irrigation through the root canal: preliminary case report.As a new nonsurgical treatment for odontogenic maxillary sinusitis (OMS), irrigation of the maxillary sinus through the root canal of the causal tooth was carried out to the patient with OMS that had proved refractory to conservative treatments (i.e., root-canal treatment of the causal tooth and antibiotic therapy). Clinical signs, symptoms, and radiographs before and after the new treatment revealed evidence of good healing. The clinical signs and symptoms, such as oppressive pain in the cheek and retrorhinorrhoea, entirely disappeared immediately after the irrigation (which was done only once) without pain, and the obstructed ostiomeatal unit was aerated on the follow-up CT images. There was no side effect associated with saline irrigation, nor any recurrence of symptoms since the irrigation. We therefore propose the irrigation through the root canal of the causal tooth as a new treatment for periapical disease-induced maxillary sinusitis, a technique that should ensure proper ventilation and drainage by relieving obstruction of the ostiomeatal unit.- - - - - - - - - - ranking = 2.3333333333333keywords = canal (Clic here for more details about this article) |
3/16. Case Report. Maxillary sinus infection due to emericella nidulans.Fungal infections of the maxillary sinus are frequently caused by Aspergillus species, particularly A. fumigatus. In otherwise healthy persons there is an association with overfilling of dental root canals, when zinc-containing filling materials were used. Below, a maxillary sinus aspergilloma is reported in a young immunocompetent female patient caused by Aspergillus (emericella) nidulans.- - - - - - - - - - ranking = 0.33333333333333keywords = canal (Clic here for more details about this article) |
4/16. Migration of gutta-percha point from a root canal into the ethmoid sinus.There have been reports on the migration of teeth or implants into the maxillary sinus, but we know of no report on the migration of a gutta-percha point that had been used to fill a root canal into the ethmoid sinus. We report such a case which presumably migrated through the maxillary sinus.- - - - - - - - - - ranking = 1.6666666666667keywords = canal (Clic here for more details about this article) |
5/16. aspergillosis of the maxillary sinus: review and case report.A case of non-invasive aspergillosis affecting the maxillary sinus is presented. Reference is made to its possible aetiology (spores introduced to the antrum at the time of a root canal overfilling with a zinc oxide paste). A review is presented and the management of the case is described.- - - - - - - - - - ranking = 0.33333333333333keywords = canal (Clic here for more details about this article) |
6/16. Aspergillus mycetoma of the maxillary sinus secondary to overfilling of a root canal.In nonimmunocompromised patients aspergillosis of the paranasal sinuses is a relatively rare disease. Root canal treated teeth with overextension of the root canal sealer or solid materials such as gutta-percha or silver cones into the sinus might be the main etiological factor for aspergillosis of the maxillary sinus in healthy patients. Root-filling materials based zinc oxide-eugenol is considered to be a growth factor for aspergillus. aspergillus fumigatus needs heavy metals such as zinc oxide for proliferation and metabolism. Prognostic and histological studies showed that instrumentation and obturation should not extend beyond the apical foramen. When the sealer and/or gutta-percha is extruded within the sinus, this produce an inflammatory reaction and then Aspergillus growth. We report one case of healthy 60-yr-old male with overextension of root canal sealer in maxillary sinus. After surgical procedure, microscopic examination revealed aspergillosis. Overextension into the maxillary sinus with root canal cements has to be avoided.- - - - - - - - - - ranking = 2.6666666666667keywords = canal (Clic here for more details about this article) |
7/16. abscess of the orbit arising 48 h after root canal treatment of a maxillary first molar.AIM: To discuss a rare, but severe complication arising following routine root canal treatment. SUMMARY: An orbital abscess is reported that occurred following routine root canal treatment. A young, healthy female patient, with no history of chronic paranasal infection had undergone root canal treatment of the right maxillary first molar. On hospital admission, she presented with extensive periorbital swelling and discreet diplopia. Computed tomography imaging identified massive purulent sinusitis and subsequent involvement of the orbit via the inferior and medial orbital wall within 48 h after completion of root canal treatment. Immediate surgical drainage of the maxillary sinus and the orbit was established and a high dose of perioperative antibiotics (amoxicillin/Clavulanic acid, Gentamycin, metronidazole) were administered. Vision remained undisturbed and mobility of the globe recovered within 10 days. KEY learning POINTS: Rapid exacerbation of a periapical inflammation may occur following root canal treatment and may even involve the orbit. A typical speed of disease progression or ophthalmic symptoms should alert the clinician to at least consider unusual early orbital spread of odontogenic infection. When extra-alveolar spread and especially orbital spread is suspected, immediate referral to a maxillofacial or other specialized unit is mandatory.- - - - - - - - - - ranking = 3keywords = canal (Clic here for more details about this article) |
8/16. Massive enlargement of the nasolacrimal canal causing epiphora and chronic maxillary sinusitis.OBJECTIVES: Enlargement of the nasolacrimal canal (NLC) is a rare anatomic variant. We present the first report of a massively dilated NLC causing epiphora and chronic sinusitis. methods: The authors conducted a literature review and case report. RESULTS: A 65-year-old man with refractory sinonasal symptoms and a remote history of a dacryocystorhinostomy was found to have a massively dilated, air-filled NLC. Using a combined endoscopic transnasal and endoscope-assisted Caldwell-Luc approach, the posterolateral wall of the NLC was removed. The patient's symptoms were improved 10 months postoperatively. CONCLUSIONS: Symptoms suggestive of nasolacrimal dysfunction should prompt a search for potential sinonasal pathology.- - - - - - - - - - ranking = 1.6666666666667keywords = canal (Clic here for more details about this article) |
9/16. Sinus aspergillosis.The prevalence of Aspergillus sinusitis is often underestimated because the vast majority of cases are classified as "unspecified sinusitis". Two possible aetio-pathogenic mechanisms can be involved in the development of this fungal infection. Traditionally, the literature emphasised the "anglophone" hypothesis which is based on the inhalation of spores. More recently, the "french" model, based on oro-sinusal fistula and/or the perforation of the maxillary sinus by root canal-filling material, is believed to explain the majority of cases in our industrialised environments. Still, neither model explains the totality of cases and several remain beyond comprehension. The disease most commonly presents as a chronic bacterial sinusitis. The process can however become invasive, thus resembling malignancy, with eventually a fatal outcome. Doctors and dentists should know the possible danger, presented by zinc-oxide-eugenol-paste in the sinus. Radical surgery is the treatment of choice, since a prolonged conservative approach (antibiotics, corticosteroids) can only worsen the prognosis. This paper discusses different aspects of the disease, and presents 10 cases, observed at the University hospitals of paris (france) and Leuven (belgium).- - - - - - - - - - ranking = 0.33333333333333keywords = canal (Clic here for more details about this article) |
10/16. Chronic sinusitis and zinc-containing endodontic obturating pastes.Several researchers have reported a link between the development of a solitary antral aspergillus sinusitis and the presence of zinc-containing root canal obturating paste within the antrum. If diagnosed correctly, it is generally accepted that this type of sinusitis can be treated effectively using surgical techniques alone. However, previous reports have shown that this is not always the case and may result in prolonged and inappropriate treatment of the condition. It is hoped that the reported case and literature review will assist both dental and medical practitioners in identifying affected patients and in the subsequent instigation of correct treatment regimes.- - - - - - - - - - ranking = 0.33333333333333keywords = canal (Clic here for more details about this article) |
