1/15. Thermal sensitivity of endodontically treated teeth.case reports: The problem of thermal sensitivity following non-surgical root-canal treatment is explored and case reports are presented. Possible causes for post-treatment discomfort from endodontic and restorative aetiologies are discussed, as are the mechanisms to explain the patients' painful experiences. Treatment of this problem may vary from the simple replacement of a defective restoration to a more extensive non-surgical retreatment of the case, despite radiographic evidence of an acceptable root filling and normal periradicular tissues.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
2/15. Odontalgia in vascular orofacial pain.A case of episodic, spontaneous odontalgia, aggravated by ingestion of cold food, with no apparent dental pathology is presented. Attempts at alleviating the pain by means of root canal treatment had failed in previous, similar episodes, and pain and pulpal hyperalgesia had shifted to other locations. Primary vascular orofacial pain was diagnosed and effective control obtained by prophylactic treatment with propranolol, a beta-adrenergic blocker. A prophylactic attempt with nifedipine, a calcium channel blocker, failed to alleviate the pain. This diagnostic entity and possible therapeutic approaches are discussed.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
3/15. Persistent pain related to root canal filling and apical fenestration: a case report.Endodontic treatments may give rise to persistent pain whose origin is sometimes difficult to determine. Although it is unusual, pain may occur due to apical fenestrations following endodontic treatment. If this occurs, the solution is surgical intervention. This surgical procedure consists of raising a flap to expose the fenestration, followed by curettage of any overextended canal filling materials that may be potentially irritating to the underlying mucosa, remodeling of the apex, and its repositioning below the level of the cortical bone. A case is described that illustrates this clinical situation. The case also demonstrates information that can be obtained from tomodensitometric films.- - - - - - - - - - ranking = 5keywords = canal (Clic here for more details about this article) |
4/15. 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 = 3keywords = canal (Clic here for more details about this article) |
5/15. Malignant lymphoma of the maxillary sinus manifesting as a persistent toothache.Many teeth have been mistakenly extracted or endodontically treated because of an incorrect diagnosis of orofacial pain, including toothache. A case of persistent toothache originating from a malignant lymphoma of the left maxillary sinus is presented. root canal therapy and extraction of the upper left quadrant teeth from the canine to the second molar did not resolve the chief complaint. The patient was referred to a neurologist and received a diagnosis of a malignant lymphoma, a rare lesion of the maxillary sinus. This case stresses the importance of considering malignant neoplasm of the maxillary sinus as a potential etiologic factor in the differential diagnosis of orofacial pain.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
6/15. Long term radiographic study of bilateral second premolars with immature root treated by apexogenesis and apexification.A ten-year-old girl broke the central cusps of the mandibular second premolars. The mandibular right second premolar was treated with apexification and the left with apexogenesis. These methods were chosen in view of the presented clinical symptoms, radiographic findings, and outcome of bacterial cultures of root canal samples. At postoperative 2 years 8 months, disappearance of the focus, closure of the root canal, and formation of the root apex were observed in both mandibular premolars. The mandibular left second premolar demonstrated a nearly normal root formation and root apex morphology. Immediately beneath the extracted pulp, regular, uniform, and thick hard tissue was formed. Meanwhile, in the mandibular right second premolar, root growth was suspended, making the root short, and the contour was constructed in such a way that it encircled the distal apical area from the mesial side forming the root apex.- - - - - - - - - - ranking = 2keywords = canal (Clic here for more details about this article) |
7/15. Cavitational bone defect: a diagnostic challenge.A patient with a history of trauma to the maxillary left anterior region presented with chronic pain of unknown etiology. root canal therapy and periradicular surgery failed to resolve the persistent pain. A second surgical procedure revealed a bone cavity superior and distopalatally to the apex of the maxillary left lateral incisor. The suspected etiology was necrotic bone removed from the bone cavity.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
8/15. Thermally induced pulpalgia in endodontically treated teeth.Two cases of thermally induced pulpalgia in teeth previously endodontically treated are presented. reproduction of the patient's chief complaint was the key to identifying the teeth involved. In both cases, the pulpalgia was stimulated by heat. After locating and treating an unfilled canal, the teeth have remained asymptomatic. Possible explanations for this occurrence are discussed.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
9/15. Flare-up with associated paresthesia of a mandibular second premolar with three root canals.A case report is presented that deals with mental nerve paresthesia resulting from the "flare-up" of a mandibular second premolar with three root canals. A review of the literature and discussion follow, which suggest possible mechanisms that may be responsible for paresthesia as well as treatment regimens that may be used to minimize the incidence of this unexpected but occasional post-treatment endodontic sequela.- - - - - - - - - - ranking = 5keywords = canal (Clic here for more details about this article) |
10/15. osteoblastoma in the anterior maxilla mimicking periapical pathosis of odontogenic origin.A patient with a 6-yr history of chronic orofacial pain and periapical pathosis in the anterior maxilla presented for evaluation and treatment. Previous root canal therapy had failed to resolve the persistent pain. Further evaluation suggested a non-odontogenic etiology of the patient's symptoms. Exploratory surgery revealed an osseous cavity across the maxillary anterior palatal midline filled with osteoid and early mineralized bone. The tumor was surgically removed in toto. A diagnosis of benign osteoblastoma was made.- - - - - - - - - - ranking = 1keywords = canal (Clic here for more details about this article) |
