Abstract
Cilj: Cilj istraživanja bilo je utvrditi kolike su razlike u količini ekstrudiranog detritusa i tekućine za irigaciju između tri različite tehnike instrumentacije jednokorijenskih zuba. Materijal i metode: U istraživanju je korišteno trideset jednokorijenskih zuba koji su podijeljeni u tri grupe (n=10) i instrumentirani rotacijskom (ProTaper), reciprocitetnom (WaveOne) i ručnom (Step-back) tehnikom instrumentacije korijenskih kanala. Kao irigans se koristila destilirana voda u iznosu od 5mL za svaki kanal. Tijekom instrumentacije, ekstrudirani detritus i tekućina za ispiranje kanala su sakupljani u Eppendorf safe-lock tubice. Tubice su pohranjene u termostat, a kada je isparila tekućina, izvagan je suhi ostatak. Količina ekstrudiranog detritusa dobivena je kao razlika između težine početno izvagane Eppendorf safe-lock tubice i tubice koja je sadržavala samo suhi ostatak. Rezultati: Instrumentacija korijenskih kanala Step-back tehnikom rezultirala je najmanjom količinom detritusa, a suprotno očekivanom, najveća količina detritusa, koja je prošla kroz apeks, nastala je nakon instrumentacije ProTaper rotacijskom tehnikom. Razlika u količini detritusa i tekućine za irigaciju koji su sakupljeni u Eppendorf safe-lock tubicama nisu bili statistički značajni. Zaključak: Iako je Step-back tehnika bila najpoštednija, sve tri tehnike instrumentacije korijenskog kanala uzrokovale su apikalnu ekstruziju detritusa i tekućine za irigaciju.

Objectives: The purpose of this study was to measure the amount of apically extruded debris and irrigant in single rooted canals using three different instrumentation systems. Material and Methods: Thirty single-rooted teeth were divided into three groups (n = 10) and instrumented using rotary (ProTaper), reciprocating (WaveOne) and manual (Step-back) technique. Bidistilled water was used as irrigant in the amount of 5mL per canal. During instrumentation, extruded debris and irrigant were collected in Eppendorf safe-lock tubes. The tubes were stored in an incubator, and when the liquid evaporated, the dry residue was weighed. The amount of apically extruded debris was obtained by substracting the mean weight of the pre-weighed Eppendorf safe-lock tube from the mean weight of the tube containing the dried debris. Results: Step-back technique resulted in the least amount of apically extruded debris and the largest amount produced the ProTaper rotary system. The difference in the amount of debris and irrigant collected in Eppendorf safe-lock tubes were statistically insignificant. Conclusion: Even though Step-back technique resulted in the least amount of apically extruded material, all instrumentation techniques extruded debris and irrigant.
