This study was conducted to observe the response of dogs' dental pulp to white mineral trioxide aggregate (MTA) when used as pulp capping material. The pulp of 15 dogs' teeth was experimentally exposed and capped with white MTA. The animals were sacrificed two months later and the specimens were prepared for histomorphological study. The pulp capped with white MTA showed a healing process with ...

INTRODUCTION Intermittent administration of parathyroid hormone (PTH) promotes oral osseous wound healing and protects against ligature-induced alveolar bone loss. However, its therapeutic value on periapical periodontitis is unknown. The goal of this study was to determine the effect of intermittent PTH administration on the progression of periapical periodontitis. METHODS Seven lymphotoxin ...

introduction: open-apex teeth with irreversible pulpitis require complex and difficult treatment. providing the right environment for apexogenesis and pulp protection is vital for their long term prognosis. the young pulp of open apex tooth, however, is better equipped against irritation and assault. the aim of this study was to evaluate pulp inflammation in open apex canine teeth of cats. mate...

Traumatic or carious exposure of a vital pulp in an immature permanent tooth presents a significant clinical challenge to maintain proper vitality. Currently available procedures include direct pulp capping, complete pulpotomy and partial pulpotomy. This paper reviews the application of partial pulpotomy in immature permanent teeth and provides prognostic and technique guidance.

introduction: the aim of this study was to determine the histologic effect of low level laser therapy (lllt) with or without the use of mineral trioxide aggregate (mta) on exposed pulp tissues of dogs. methods: twenty-five premolar teeth in three healthy mature dogs were randomly divided into five groups. in group 1, the pulp tissue was capped with mta. in groups 2 and 3, before capping with mt...

This study evaluated the short-term response of human pulp tissue when directly capped with Portland cement. In this series of cases, twenty human third molars that were scheduled for extraction were used. After cavity preparation, pulp exposure was achieved and Portland cement pulp capping was performed. Teeth were extracted after 1, 7, 14 and 21 days following treatment and prepared for histo...

OBJECTIVES The aim of the present study was to investigate pulp survival following crown fracture with and without pulp exposure as well as with and without associated subluxation and in relation to stage of root development and type of enamel-dentine fracture. MATERIALS AND METHODS This study consisted of 83 patients with 116 crown fractured incisors without pulp exposure and 35 patients wit...

OBJECTIVES Polymerized dental resin materials release residual monomers that may interact with pulp tissues. We hypothesized that dental adhesives might cause cytotoxicity in pulp cells via the generation of reactive oxygen species (ROS), which may also contribute to genotoxic effects in vitro. METHODS For cytotoxicity testing, transformed human pulp-derived cells were exposed to extracts of ...

The consequences of pulp exposure from caries, trauma or tooth preparation misadventure can be severe, with pain and infection the result. The morbidity associated with treating pulp exposures is consequential, often requiring either extraction or root canal therapy. Both the loss of the tooth and its replacement, or endodontic treatment and tooth restoration, involve multiple appointments and ...
