This article describes the use of three devices that replace the wax rims in the registration of the intermaxillary position and of the vertical dimension of occlusion in completely edentulous patients who have been treated with Brånemark implants. The devices consist of a mechanical "tooth" that can be adjusted in all three dimensions of space and of two plates that support the registration ma...

OBJECTIVE Hydroxyl (OH-) and calcium (Ca++) ion release was evaluated in six materials: G1) Sealer 26, G2) White mineral trioxide aggregate (MTA), G3) Epiphany, G4) Epiphany + 10% calcium hydroxide (CH), G5) Epiphany + 20% CH, and G6) zinc oxide and eugenol. MATERIAL AND METHODS Specimens were placed in polyethylene tubes and immersed in distilled water. After 3, 6, 12, 24, and 48 h, 7, 14, a...

OBJECTIVES The aim of this study was to determine the probable side effects of electrosurgery in pulpectomy of deciduous teeth on succedaneous teeth in dogs. MATERIALS AND METHODS In this animal study, all maxillary and mandibular teeth at one side of five puppies' mouths were treated employing electrosurgical pulpectomy and were then compared with those of the other side treated using the co...

INTRODUCTION The aim of this study was to evaluate the effects of eugenol-free temporary cement's remnants on the retentive strength of full metal crowns luted via zinc phosphate and resin cement (Maxcem) to the tooth structure. MATERIALS AND METHODS Forty complete standardized Ni-Cr crowns in four groups were cemented by two types of permanent cements: zinc phosphate cement and resin cement ...

background : incidence of  white  spots due  to  demineralization of  enamel  and  gingival problems  is  an  unacceptable  result  of  orthodontic  treatment.  plaque  accumulation  and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...

AIM To compare histological responses to zinc oxide-eugenol (ZOE) and calcium hydroxide (CH) pulpectomies in primary molar teeth with inflamed pulps. STUDY DESIGN This was an experimental study in 17 juvenile baboons (Papio ursinus). METHODS Pulpitis was induced with fresh human carious dentine or Streptococcus mutans placed into occlusal cavities in 78 primary molars; after 14 days a pulpe...

Using Coreopsis tinctoria liquid cultures of Agrobacterium rhizogenes transformed roots (socalled “hairy roots”) and non-transformed roots have been established. The production of differ­ ent phenylpropanoid compounds by these cultures grown in light or darkness, respectively, was compared. Whereas the composition of phenylpropanoids in the root cultures was not influenced by the culture condit...

The oxidation of eugenol (4-allyl-2-methoxyphenol) by horseradish peroxidase was studied. Following the initiation of the reaction with hydrogen peroxide, eugenol was oxidized via a one-electron pathway to a phenoxyl radical which subsequently formed a transient, yellow-colored intermediate which was identified as a quinone methide. The eugenol phenoxyl radical was detected using fast-flow elec...

EUGENOL a widely used pharmaceutical agent proceeds toxicity on inhalation in rats. Two different doses 20 & 30 μg/100g body weight/ day of eugenol were given intramuscularly to male albino rats for 10 days and the liver function was assessed by measuring the specific enzyme activities, and total and differential bilirubin concentration. There was an appreciable increase in total as well as dif...
