Acute exacerbation of symptoms, or "flare-up," after the debridement of the root canals and provisional restoration is a well-known postoperative complication of endodontic treatment. In this clinical study, various types of intracanal medications were compared for their ability to decrease interappointment flare-ups. The result showed that use of(More)
A computerized telemetric system using a portable microprocessor receiving unit has been designed for clinical use in ambulatory 24-hour esophageal pH monitoring. The receiving unit can be used with either a pH-sensitive radiotelemetry pill or a standard intraesophageal pH probe. Esophageal pH data is collected under microprocessor control while the patient(More)
Acute exacerbation of symptoms during the inter-appointment time interval of endodontic treatment is a well-known complication. The phenomenon is termed "flare-up" by most researchers and clinicians, although the exact definition of it differs from one author to another, making it difficult to compare the results of the studies.

The peroxydatic activity of haemoglobin in the presence of hydrogen peroxide catalyses the oxidation of TMB to a coloured product. Haemoglobin peroxidase has been termed a 'pseudoperoxidase'7 because, unlike true peroxidases which exhibit specificity for phenols, erythrocytes contain a peroxidase (erythrocyte glutathione peroxidase) specific for oxidation(More)
