Comparison of apical debris extrusion during root canal preparation in primary molars using different file systems: an in vitro study

Abstract

This study aimed to compare the amount of debris extrusion of four endodontic systems made of Nickle‐Titanium alloy. This in vitro study was done on 80 extracted primary molars. They were selected by cone‐beam computed tomography and randomly divided into four groups (n = 20) to be prepared to the apical size of 25 by one of the systems: Reciproc, Protaper Universal, Neolix, or Hyflex CM. Debris was collected into Eppendorf microtubes and placed in an incubator to evaporate the washing solution. Debris was weighed by a digital scale of 0.01 g precision. Data were statistically analysed using SPSS software. Tukey’s comparison was used to determine the difference between the four file systems (α = 0.05). Debris extrusion after Reciproc preparation (0.00320) was significantly higher than the other (P < 0.05), with no significant difference having been observed among the other systems (P > 0.05). It can be concluded that all systems under investigation exhibited debris extrusion.

Update in the Diagnosis and Treatment of Root Canal Therapy in Temporary Dentition through Different Rotatory Systems: A Systematic Review

“…Regarding the sample included in the studies obtained ( Table 1 and Table 2 ), most of them analyzed an average of 30 teeth [ 10 , 11 ]. Highlighting Mohammadi, D [ 12 ], with a maximum of 80, and Moraes [ 13 ] with a minimum of 1. Regarding the variables analyzed, and considering the length of the files, the longest were those used by Gekelman [ 14 ], with a length 25 mm, and the shortest, 15 mm, used by Mohammadi [ 12 ].…”

It should be noted that the mean length used in most studies was 21 mm [ 15 ].…”

“…Regarding the speed of the files, 300 rpm is usually recommended for performing pulpectomies. However, authors such as Mohammadi, D [ 12 ] have used higher speeds such as 1200 rpm.…”

“…However, the rotary files generally used by clinicians and most commonly described in the literature are designed specifically for endodontic treatment of permanent teeth and not for its use in the primary dentition. Furthermore, there is no specific protocol for rotary instrumentation in primary teeth [ 12 ].…”

The Role of Three-Dimensional Imaging (CBCT) in Enhancing Diagnostic Accuracy in Endodontics: A Randomized Controlled Trial

“…[ 1 ] Endodontic procedures primarily involve the treatment of dental pulp and periapical tissues within the tooth, and precise diagnosis is pivotal for effective management. [ 2 ] Historically, two-dimensional radiography, including periapical and panoramic radiographs, has been the standard imaging modality for assessing endodontic conditions. [ 3 ] However, the limitations of conventional radiography, such as the superimposition of anatomical structures and the inability to provide a three-dimensional view, have prompted the exploration of alternative imaging techniques.…”
