RESUMEN
Taurodontism is a rare dental anomaly in which the involved tooth has enlarged and elongated body and pulp chamber with apical displacement of the pulpal floor. Endodontic treatment of these teeth is challenging because it requires identifying the number of root canals. A case of bilateral involvement of maxillary first molar teeth is presented. Endodontic treatment of the right maxillary first molar with taurodontism was indicated due to irreversible pulpitis. In this article, we described the procedure of root canal therapy for this case
RESUMEN
Dental plaque and periodontal pockets might be a reservoir for Helicobacter pylori which is a factor for recurrence of alimentary system problems. The aim of this study was assessment of helicobacter pylori in dental plaque, periodontal pockets and stomach samples of patients with dyspepsia. In this descriptive study, 96 patients [45 Males and 51 females] refferred to Ecbatan hospital with dyspeptic complaints, were randomly selected. After filling out the questionnaire, samples of subgingival plaque and periodontal pocket were prepared in every patient. Then the patients were examined by endoscopy. All the samples were collected and were assessed for detection of Helicobactor pylori [HP] by polymerase chain reaction [PCR]. In 96 of dyspeptic patients with mean age of 37.28 yr, negative PCR in all samples was detected. It can be concluded that dental plaque and periodontal pockets could not be a reservior for HP, and do not play a role in recurrence or incidence of dyspepsia in these patients
