severe traumatic injuries to immature teeth often cause damage to periodontal ligament as well as dental pulp; pulp necrosis, root resorption and subsequent apical lesion are common consequences. this article reports the surgical management of an infected immature maxillary central incisor associated with a gigantic periradicular lesion and severe root resorption. the tooth had a history of tra...

effects of using n-3 hufa-enriched artemia and non-enriched artemia as the starter food for growth and survival of rainbow trout larvae compared to commercial concentrated food were investigated in this study. the larvae with average weight of 92.9 mg were fed for 20 days with four food treatments included of commercial concentrated food, newly hatched artemia, enriched artemia, and mixture of ...

statement of the problem : in clinical situations, calcium-enriched mixture (cem) comes into direct contact or even mixes with blood during or after placement. purpose: the aim of this study was to evaluate the effect of blood contamination on the compressive strength of cem. materials and method: three experimental groups were included in this study. in the first group, cem was mixed with dist...

introduction: the aim of this study was to evaluate the compressive strength of calcium-enriched mixture (cem) cement in contact with acidic, neutral and alkaline ph values. methods and materials: the cement was mixed according to the manufacturer’s instructions, it was then condensed into fourteen split molds with five 4×6 mm holes. the specimens were randomly divided into 7 groups ( n =10) an...

background and aims. the aim of this study was to compare the biocompatibility of calcium-enriched mixture ce-ment (cem), composite resin and nano-particled mineral trioxide aggregate (np-mta) using human gingival fibroblasts. materials and methods. a comparative in vitro cell culture study was carried out using 60 single-rooted teeth which were assigned to the following four groups: 1) untreat...

introduction: this in vitro study compared the cytotoxic effects of three commercially available mta formulations naming proroot mta (pmta), angelus mta (amta), and root mta (rmta), with calcium-enriched mixture (cem) cement and a new nanohybrid mta (nmta) on human dental pulp stem cells (dpsc). methods and materials: four disc-shaped specimens of each material were prepared. after completion o...

INTRODUCTION The aim of this study was to compare the discoloration potential of calcium-enriched mixture (CEM) cement, white mineral trioxide aggregate (WMTA) and calcium hydroxide (CH), after placement in pulp chamber. METHODS AND MATERIALS Access cavities were prepared in 40 intact maxillary central incisors. Then, a 2×2 mm box was prepared on the middle third of the inner surface on the b...
