NCT06752837

Brief Summary

Background: This study used cone-beam computed tomography (CBCT) to compare a stainless-steel Tornado file system with OneShape and WaveOne rotary systems for biomechanical canal preparation as indicated by the healing of periapical lesions. Methods: Lower molars with necrotic pulps and periapical lesions were arbitrarily divided into three groups (n=20) rendering to three rotary file systems. After root canal treatment, clinical and radiographic assessment of the apical radiolucency was evaluated at one year using pre- and post-instrumentation CBCT images. Statistical analysis was performed to compare the three systems at a p-value of 0.05.

Outcome Measures

Primary Outcomes (1)

  • Three-dimension lenght in millimeter for apical radiolucency in CBCT for each pateint

    A post-operative Cone beam computed tomography(CBCT) image was obtained and compared to the pre-operative one to assess the impact of canal preparation of each file on the periapical lesion based on Estrela et al CBCT periapical index (CBCT PAI). The radiolucent area of the periapical lesion was measured in millimeters for the three dimensions on the CBCT scan. Bucco-palatal, mesiodistal, and diagonal measurements were obtained, and the greatest diameter was recorded for scoring the lesion extension. Measurements were conducted simultaneously and independently by two examiners and any discrepancies were discussed and remeasured for one measurement agreement.

    One-year follow-up visit for each pateint

Secondary Outcomes (1)

  • Qualitative scoring for clinical criteria for each pateint

    One-year follow-up visit for each pateint.

Interventions

In arm one, stainless steel tornado files works by high-speed rotation that influences the fluid dynamics within the canal and improves irrigation efficiency. Canals are finished with a file having a 4% taper and an apical diameter of 0.25 mm.

Also known as: Revolving SS Tornado rotary system (MIB, FRANCE) in arm one
The instrumentation was done using a revolving SS Tornado rotary system (MIB, FRANCE).

In arm two, WaveOne system is a single reciprocating file system with a heat-treated NiTi Memory Wire (M Wire).It has a taper of 0.08 in apical 3 mm, with a tip diameter of 0.25 mm. in a torque control endodontic handpiece (X smart plus with reciprocation mode)

Also known as: In arm two, WaveOne single reciprocating file system
Instrumentation was done using a reciprocating Ni-Ti WaveOne system (Dentsply Maillefer, Ballaigues,

In arm three, OneShape system utilizes a conventional, continuous rotational motion. It has asymmetric cross-sectional geometry, and traveling waves of motion that are produced along the file's active region. It has a single constant taper of 0.06 and a tip size of 25 with distinct cross-sectional designs along the whole length of the working parts

Also known as: In arm three, OneShape rotary system
The instrumentation was done using a rotative Ni-Ti OneShape system (Micro Mége, Besançon, France).

A post-operative CBCT image was obtained and compared to the pre-operative one to assess the impact of canal preparation of each file on the periapical lesion.

Also known as: Operating teeth were scanned with an axial slice thickness of 0.1 mm using a CBCT (Kodak 9000C) with an 80 kV, 4 mA, 51 × 51 mm field of view, and 0.1/voxel (mm) size.
