| description | Objective:
To evaluate the residual debris and smear layer
formation, and also preparation time of one or multifile manual, rotary, and
reciprocal systems on primary teeth.
Materials and methods: A total of 75
primary mandibular molar teeth were randomly divided to five groups (n=15). The
distal canals of teeth were shaped with each of the K file, Protaper, Twisted
File, OneShape, and Reciproc systems. Preparation time was also recorded. Longitudinal
sections groups were prepared and processed for observation under scanning
electron microscopy (SEM) at a standard magnification of X1000 for smear layer
and X200 for residual debris. The presence of smear layer and residual debris was
evaluated by two trained operators. The data of preparation time and also
debris and smear scores were analyzed using ANOVA and the Kruskal-Wallis test,
respectively.
Results: Reciproc and OneShape systems had significantly less
instrumentation time than all other groups (p<0.001). The results of
statistical analyses were the same for the residual debris and smear layer scores.
In the coronal thirds of the canals, the canal preparation with the Protaper
system resulted in significantly less debris and smear layer compared with the
OneShape system (p=0.015). In the middle thirds of the canals, OneShape and
Reciproc systems had more residual debris and smear layer than the Protaper
system (p<0.05). In the apical thirds of the canals, the use of the Protaper
instruments resulted in less debris and smear layer than the Reciproc system
(p=0.034).
Conclusion:
Within the limits of this study, the Protaper system,
which showed better cleaning efficacy and was also faster than the manual
system, can be an effective alternative to other systems in the root canal
treatment of primary molars. More in vitro and clinical investigations are
needed on root canal treatment of primary teeth. |
