Sixty-three vital permanent incisors with complicated crown fractures were treated by partial pulpotomy and assessed clinically and radiographically for healing. Healing of the pulp was considered to have taken place when the following criteria were fulfilled: absence of clinical symptoms, radiographic evidence of dentin bridge formation, no intrapulpal or periapical pathosis, continued root de...

Pulps removed from a series of 21 crown-fractured incisors, which had been treated by partial pulpotomy and which had been clinically judged as healed 12 to 95 months (mean 52 months) after treatment, were examined histologically. In five pulps a few, scattered lymphocytes were seen, and in one pulp there was a slight infiltration with lymphocytes and a few plasma cells. In 10 pulps calcificati...

BACKGROUND Several medicaments have been used to devitalize remaining pulp or maintain pulp vitality and promote healing. Based on pulpal biocompatibility and good sealing ability, a growing interest in more biocompatible materials promotes mineral trioxide aggregate (MTA) as an alternative to traditional medicaments. Uniquely, MTA can preserve pulpal health predictably and promote healing with...

vitality of dental pulp is essential for long-term tooth survival. the aim of vital pulp therapy is to maintain healthy pulp tissue by eliminating bacteria from the dentin-pulp complex. there are several different treatment options for vital pulp therapy in extensively decayed or traumatized teeth. pulp capping or pulpotomy procedures rely upon an accurate assessment of the pulp status, and car...

rhizoctonia-like fungi were isolated from the infected roots of miniature rose (rosa hybrida cv. linda) plant with chlorosis and necrosis symptoms, grown in commercial glasshouse in rafsanjan, iran, during the autumn of 2011. all of the isolates were identified as binucleate rhizoctonia sp. on the basis of hyphal characteristics and nuclei number. they were tested for detection of the anastomos...

Objective: The use of miniature X-ray source in electronic brachytherapy is on the rise so there is an urgent need to acquire more knowledge on X-ray spectrum production and distribution by a dose. The aim of this research was to investigate the influence of target thickness and geometry at the source of miniature X-ray tube on tube output.Method: Five sources were simulated based on problems e...

seven caspian miniature horses, aged above two years, were used for this study. the skeleton of these horses were cleaned and prepared using appropriate techniques. the vertebral column was studied and photographed. the vertebral column in one of these horses showed variations in thoracic, lumbar and sacral region. the vertebral formola was c7, t19,l5,s6 and a pair of 19th rib was fused with th...
