| Summary: | Introduction: Pulp therapy in primary teeth has been performed
using various instrumentation techniques. However, the
conventional instrumentation technique used for root canal
preparation in primary teeth is hand instrumentation. Various
Nickel-Titanium (Ni-Ti) instruments are available to perform
efficient root canal preparation in primary teeth. These NiTi instruments has been designed to aid in better root canal
preparation in permanent teeth but are rarely used in primary
teeth. It is necessary to assess the feasibility of using these
adult rotary files with a modified sequence in primary teeth.
Aim: To compare the quality of obturation and instrumentation
time during root canal preparation using hand files and modified
rotary file systems in primary molars.
Materials and Methods: Forty-five primary mandibular molars
were randomly assigned to three experimental groups (n=15).
Group I was instrumented using k-hand files, Group II with S2
ProTaper universal file and Group III with 0.25 tip 4% taper K3
rotary file. Standardized digital radiographs were taken before
and after root canal instrumentation. Root canal preparation
time was also recorded. Statistical analysis of the obtained data
was done using SPSS Software version 17.0. An intergroup
comparison of the instrumentation time and the quality of
obturation was done using ANOVA and Chi-square test with the
level of significance set at 0.05.
Results: No significant differences were noted with regard
to the quality of obturation (p=0.791). However, a statistically
significant difference was noted in the instrumentation time
between the three groups (p<0.05). ProTaper rotary system had
significantly lesser instrumentation time when compared to that
of K3 rotary system and hand file system.
Conclusion: The hand files, S2 ProTaper Universal and K3 0.25
tip 4% taper files systems performed similarly with respect to
the quality of obturation. There was a significant difference in
instrumentation time with manual instrumentation compared to
the modified rotary file systems in primary teeth. |
