Endodontic Retreatment with Eucalyptol and Chloroform Solvent

Abstract

Kloroform je bio najčešće rabljena otopina za otapanje gutaperke u korijenskom kanalu. Rasprave o sigurnosti njegove uporabe potakle su uporabu novih tekućina za otapanje gutaperke. Svrha rada bila je usporediti djelotvornost i vrijeme potrebno za otapanje gutaperke eukaliptolom i kloroformom. Trideset jednokorijenskih zuba sterilizirano je, obrađeno i ispunjeno gutaperkom, te pohranjeno u 0,9% otopini Na- Cl sedam dana. Uzorci su podijeljeni u dvije skupine. Jedna je tretirana eukaliptolom, a druga kloroformom. Revizija se smatrala završenom kad više nije bilo vidljivih tragova gutaperke na metalnim instrumentima i papirnim štapićima. Zubi su uzdužno rascijepljeni i fotografirani. Površine zaostatne gutaperke i punila izmjerene su računalnim programom. Rezultati su statistički obrađeni Student t-testom i pokazali su da nema značajne razlike u otapanju gutaperke između dviju skupina.Chloroform has been the most widely used solvent in endodontic retreatment, but due to concerns about its safety, alternatives have been sought. The purpose o f this study was to compare the effectiveness of gutta-percha removal and time of retreatment between eucalyptol and chloroform used as solvents. Thirty single root teeth were sterilized, prepared, obturated, and stored in 0.9 % physiological solution (Na- Cl) for seven days, after which they were randomly divided into two groups for retreatment. The teeth were retreated using either eucalyptol or chloroform as the solvent. Retreatment was deemed complete when there was no evidence o f gutta-percha on the files or paper points. Teeth were split longitudinally and photographed. The surfaces of remaining gutta-percha and sealer were measured using computer software. The results showed no significant difference in gutta-percha removal between the two groups
