Materijali i postupci: Ploče krvnog agara inokulirane su zasebno bakterijama Streptococcus mutans, Streptotoccus mitis, Lactobacillus acidophilus, Staphylococcus aureus i Enterococcus faecalis te polimikrobnom suspenzijom od svih testiranih bakterija. Na inokulirane ploče bili su raspoređeni uzorci materijala i nakon 48 sati inkubacije očitane su zone inhibicije (ZI) u milimetrima promjera. Rezultati: Najsnažniji antibakterijski učinak MTA je pokazao kod bakterije Streptococcus mutans (ZI =7,6 mm, s.d. 1,0), zatim prema Streptotoccus mitis i Lactobacillus acidophilus (ZI=7,3 mm, s.d. 0,5). ZI za Enterococcus faecalis iznosio je 5,6 milmetara, s.d. 0,7, a za polimikrobnu suspenziju 5,3 milimetra, s.d. 1,0. Jedina bakterija na koju MTA nije imao antibakterijski učinak jest Staphylococcus aureus. Amalgam nije pokazao antibakterijski učinak na ni jednu ispitivanu bakteriju. Zaključak: MTA je pokazao antibakterijski učinak prema četiri od pet ispitivanih bakterija i polimikrobnih suspenzija, a amalgam nije inhibirao rast ni jedne testirane bakterije.

Surgical replacement of huge rate of root end amalgam filling with mineral trioxide aggregate angelus: A case report
BACKGROUND AND AIM: Surgical endodontics may sometimes fail despite using root-end filling materials (REFMs). In this case report, a symptomatic right maxillary first premolar underwent periradicular surgery (PS) for replacing huge rate of amalgam with mineral trioxide aggregate (MTA).CASE REPORT: A thirty-year-old healthy woman attended with the chief complaint of recurrent swelling and absces...
متن کاملUse of mineral trioxide aggregate for repair of furcal perforations.
The histologic response to intentional perforation in the furcations of 28 mandibular premolars in seven dogs was investigated. In half the teeth, the perforations were repaired immediately with either amalgam or mineral trioxide aggregate; in the rest the perforations were left open to salivary contamination before repair. All repaired perforations were left for 4 months before histologic exam...

UNLABELLED Microorganisms remaining in dentin following cavity preparation may induce pulp damage, requiring the use of pulp-capping agents with antimicrobial activity underneath permanent restorations. OBJECTIVE The aims of this study were to analyze the bacteriological status of carious dentin and to assess the efficacy of different base underneath silver amalgam restorations. MATERIAL AN...
متن کاملSealing ability of a mineral trioxide aggregate for repair of lateral root perforations.
Amalgam, IRM, and a mineral trioxide aggregate were tested for repair of experimentally created root perforations. Fifty sound, extracted mandibular and maxillary molars were used in this study. A perforation was created on the mesial root surface at about a 45-degree angle to the long axis of each tooth. The tooth was then placed into a saline-soaked "Oasis" to simulate a clinical condition. A...
متن کاملA comparative evaluation of the sealing ability of Mineral Trioxide Aggregate, High Copper Silver Amalgam, Conventional Glass Ionomer Cement, and Glass Cermet as root end filling materials by dye penetration method
Objective: The Purpose of this investigation was to assess the effectiveness of Mineral Trioxide Aggregate in providing an apical seal in comparison with High Copper Silver Amalgam, Conventional Glass Ionomer Cement Type 2, and Glass Cermet cement by using a dye penetration method. Methods: The root canals of seventy extracted teeth were instrumented and obturated with gutta-percha. Each tooth ...
