an experiment was conducted to determine the effect of paclobutrazol (pbz) and different irrigation amount on growth of aerial parts, leaf minerals and root performance in young olive plants cv. ‘manzanillo’ in the department of horticulture, faculty of agriculture, tarbiat modarres university in 2000. a split plot experiment in time was used based on a completely randomized block design with f...

The aim of this study was to examine the potential relationship between the occurrence of orthodontic root resorption and presence of dental anomalies such as tooth agenesis and pipette-shaped roots. Dental anomalies and root resorption were assessed on dental panoramic tomographs (DPT) of 88 subjects, 27 males and 61 females, mean age 28.4 (SD = 11.3 years), selected from orthodontic patients ...

taurodontism is a rare dental anomaly in which the involved tooth has an enlarged and elongated body and pulp chamber with apical displacement of the pulpal floor. endodontic treatment of these teeth is challenging, because it is hard to identify the number of root canals. in this article a case of bilateral involvement of maxillary first molars is presented. endodontic treatment of right maxil...

Introduction: Effective post-operative pain management is one of the problems following root canal treatment. Nonsteroidal anti-inflammatory drugs (NSAIDs) are the most commonly prescribed analgesics in endodontics. The aim of this study was to evaluate the effectiveness of naproxen in controlling pain following root canal treatment in teeth with irreversible pulpitis. Materials and methods: T...

A major anatomical variant of the two-rooted mandibular first molar is a tooth with an additional distolingual third root: The radix entomolaris (RE). It is essential to anticipate and find all roots and canals during root canal treatment. Proper angulations and interpretation of radiographs help to identify pulp chamber and root anatomy. If present, an awareness and understanding of this unusu...

familiarity with the intricacies and variations of root canal morphology is essential for successful endodontic treatment. maxillary central and lateral incisors are known to be single-rooted with one canal, however, this case report describes endodontic treatment of maxillary central and lateral incisors with two buccopalatal root canals.
