OBJECTIVES The purpose of this study was to analyze the prevalence, demographic patterns and management of odontogenic infections in patients undergoing treatment in an outpatient dental emergency service of a university hospital. MATERIALS AND METHODS In a retrospective study of the year 2012, all patients suffering from odontogenic infections were included. Demographic data, diagnosis and t...

Previous studies indicate that the astroglial glutamate-glutamine shuttle may be involved in acute pulpal inflammatory pain by influencing central sensitization induced in nociceptive neurons in the trigeminal subnucleus caudalis [the medullary dorsal horn (MDH)] by application of an inflammatory irritant to the rat tooth pulp. The aim of this study was to test if intrathecal application to the...

The diagnosis of cracked tooth is difficult in the early stage because the symptoms are not consistent, and often a crack line is not visible. Early detection and proper treatment of cracked tooth are important because all cracks have the potential to become a split tooth. 1. Be reminded that cracked tooth occurs usually on mandibular and maxillary first molars in patients in their 40s and 50s....

Objective. This study presents a clinical and histological evaluation of human pulp tissue responses after direct capping using a new dentin adhesive system. Methods. Twenty-eight caries-free third molar teeth scheduled for extraction were evaluated. The pulps of 22 teeth were mechanically exposed and randomly assigned to 1 of 2 groups: Single Bond Universal or calcium hydroxide. Another group ...

Human dental pulp inflammation can progress to periapical lesion formation and conventional root canal treatment (RCT) has been the traditional method for disease management. This observational study presents two cases of vital pulp therapy in mature molars diagnosed with irreversible pulpitis and associated with apical periodontitis. In these two clinical cases, the involved teeth had deep car...

INTRODUCTION This study examines the antibiotic prescription in dentists participated in 9(th) Congress of Iranian Association of Endodontists in Esfahan/2006. MATERIALS AND METHODS A questionnaire for this cross sectional study was designed for evaluating the patterns of antibiotic prescription. It included some demographic information, clinical signs, and conditions in need for antibiotic a...

Material and Methods: Children as dental patients, a study The records of 100 children between age 2-10 years visiting a pediatric dental clinic for various pulpal and periapical conditions were evaluated. A total of 364 procedures (pulp therapies such as pulpotomy and pulpectomy, and extractions) were carried out in the children for different pulpal and periapical pathologies (irreversible pul...

Clinically, irreversible pulpitis is treated by the complete removal of pulp tissue followed by replacement with artificial materials. There is considered to be a high potential for autologous transplantation of human dental pulp stem cells (DPSCs) in endodontic treatment. The usefulness of DPSCs isolated from healthy teeth is limited. However, DPSCs isolated from diseased teeth with irreversib...

Special AT-rich sequence binding protein 2 (SATB2) is a member of the special family of AT-rich binding transcription factors and has a critical role in osteoblast differentiation and craniofacial patterning. However, the expression and distribution of SATB2 in tooth development is largely unknown. The aim of the present study was to detect the expression and distribution of SATB2 during murine...

The present study tested the hypothesis that the amount and severity of preoperative pain will affect the anesthetic efficacy of inferior alveolar nerve block (IANB) in patients with symptomatic irreversible pulpitis. One-hundred seventy-seven adult volunteer subjects, actively experiencing pain in a mandibular molar, participated in this prospective double-blind study carried out at 2 differen...
