| description | Introduction: The intention of root canal preparation is to reduce
infected content and create a root canal shape allowing for a well
condensed root filling. Therefore, it is not necessary to remove
excessive dentine for successful root canal preparation and
concern must be taken not to over instrument as perforations can
occur in the thin dentinal walls of primary molars.
Aim: This study was done to evaluate the time preparation, the
risk of lateral perforation and dentine removal of the stainless steel
K file and K3
rotary instrumentation in primary teeth.
Materials and Methods: Seventy-five primary molars were
selected and divided into three groups. Using spiral computed
tomography the teeth were scanned before instrumentation. Teeth
were prepared using a stainless steel K file for manual technique.
All the canals were prepared up to file size 35. In K3
rotary files
(.02 taper) instrumentation was done up to 35 size file. In K3
rotary
files (.04 taper) the instrumentation was done up to 25 size file
and simultaneously the instrumentation time was recorded. The
instrumented teeth were once again scanned and the images
were compared with the images of the uninstrumented canals.
Statistical Analysis: Data was statistically analysed using Kruskal
Wallis One-way ANOVA, Mann-Whitney U-Test and Pearson’s Chisquare Test.
Results: K3
rotary files (.02 taper) removed a significantly less
amount of dentine, required less instrumentation time than a
stainless steel K file.
Conclusion: K3
files (.02 taper) generated less dentine removal
than the stainless steel K file and K3
files (.04 taper). K3
rotary files
(.02 taper) were more effective for root canal instrumentation in
primary teeth. |
