Abstract
The aim of this study was to compare the efficiency in both, preparation time and root canal shape, when using the Nickel Titanium (Ni-Ti) rotary and K-Files hand instrumentation on root canal preparation of single rooted primary teeth. Material and methods: Sixty single rooted primary teeth were selected and divided into two equal groups: Group (1) 30 teeth instrumented with manual K- files and group (II) 30 teeth instrumented with Ni-Ti rotary files (ProFile 0.04). Instrumentation times were calculated and root canal impressions were taken with light bodied silicone in order to evaluate the shape. The data was analyzed with SPSS program using the t-test and the Chi-square test to compare their means. Results: The preparation time with group (I) K- files was significantly higher than ni group (II) rotary files (ProFile 0.04), with a=p .005. The ProFile system showed a significantly more favorable canal taper when compared to the K-files system (P= 002) Conclusions: The use o f rotary files in primary teeth has several advantages when compared with manual K files: the efficiency in both, preparation time and root canal shape. 1. A decreased working time, that helps maintain patient cooperation by diminishing the potential for tiredness. 2. The shape of the root canal is more conical, favoring a higher quality of the root canal filling, and increasing clinical success
