Radiation-induced gastrointestinal syndrome, including nausea, diarrhea and dehydration, contributes to morbidity and mortality after medical or industrial radiation exposure. No safe and effective radiation countermeasure has been approved for clinical therapy. In this study, we aimed to investigate the potential protective effects of seabuckthorn pulp and seed oils against radiation-induced a...

INTRODUCTION The aim of this randomized clinical trial was to compare the histologic pulp tissue response to one-step direct pulp capping (DPC) and miniature pulpotomy (MP) with mineral trioxide aggregate (MTA) after application of dexamethasone in healthy human premolars. METHODS AND MATERIALS Forty intact premolars from 10 orthodontic patients, were randomly chosen for DPC (n=20) or MP (n=2...

PURPOSE The aim of this study was to compare the effect of mineral trioxide aggregate (MTA) to that of formocresol (FC) as pulp dressing agents in pulpotomized primary molars with carious pulp exposure. METHODS Forty-five primary molars of 26 children were treated by a conventional pulpotomy technique. The teeth were randomly assigned to the MTA (experimental) or FC (control) group by a toss ...

introduction: apexogenesis is a way to save vitality of open apex damaged teeth with mild or moderate pulp involvement. such teeth are not repaired through normal and usual treatments. this treatment provides usual and physiological conditions for root to develop in normal length. the aim of this study was to determine the success rate of apexogenesis according to the duration of pulp exposure....

This report describes the 10-year follow-up data of a patient who underwent fragment reattachment to the maxillary central incisor after coronal fracture with pulp exposure as well as the procedures followed for functional and esthetic adjustments. A 9-year-old female patient presented at the clinic of dentistry at the State University of Rio de Janeiro with a coronal fracture and pulp exposure...

Traumatic dental lesions are found at all ages, but most frequently in the paediatric population, in an age range of 2–5 years, a time period in which the muscle co-ordination and mental faculties of the child have still not been fully developed (1-2). At the age of 5, 1/3 of children have already suffered trauma of the deciduous teeth with fractures of the corona (26%), radicular fractures (3%...

In an investigation designed to determine the relation of apical infections of teeth to systemic disease, one important phase of the program was a correlation of the bacteriological, roentgenological, and anatomical findings of the teeth with the clinical course and the lesions observed in man at post mortem. Details of the methods used and some of the results have been published by Burket.' St...

OBJECTIVES Cone-beam dental computerize tomography (CBCT), a noninvasive imaging method, was used to image the pulp-dentin complex. Pulp changes histologically with aging. While many studies have investigated the histological changes in pulp, few studies have focused on the changes in the shape of the root canals. This study evaluated the changes in the root canals with aging of central superio...

introduction: the partial removal of dental caries aiming to maintain the integrity of the pulp has been considered the therapy of choice in the treatment of deep carious lesions, as long as certain principles of diagnosis are respected. dentists are always looking for techniques to remove the decayed tissue with biosafety, what provides more comfort to the patient especially when it comes to c...

Damaged dental pulp undergoes oxidative stress and 4-hexylresorcinol (4HR) is a well-known antioxidant. In this study, we aimed to evaluate the therapeutic effects of 4HR ointment on damaged pulp. Pulp cells from rat mandibular incisor were cultured treated with or resveratrol (1–100 ?M). These treatments (10–100 ?M) exerted protective effect during subsequent hydrogen peroxide treatments. The ...
