Brief summary
This study was conducted to compare the antibacterial effect and degree of postoperative pain of single rotary and reciprocating file systems during endodontic therapy
Detailed description
Introduction: Instrumentation kinematic is one of the many aspects of shaping files that underwent heavy development through the last decade. The impact of the type of motion used to drive shaping instruments was heavily studied but mostly in-vitro. More randomized clinical trials are needed to achieve a reliable body of data concerning the issue. Aim: This study aimed to evaluate the effect of varying shaping files' kinematics on bacterial reduction, post-operative pain and the incidence of flare-ups. Methods: Necrotic, asymptomatic, single-rooted mandibular premolars with single canals were used in the study, where 46 patients were randomly allocated to two groups. In the first group, WaveOne Gold was used for mechanical preparation while One Shape was used in the second group. Samples were taken preoperatively (S1) and after chemomechanical preparation (S2). Bacterial reduction was evaluated and compared between both groups via culturing technique and quantitative analysis by real-time polymerase chain reaction (qPCR). Post-operative pain and the incidence of flare-ups were also evaluated using the visual analog scale (VAS) method.
Interventions
root canal treatment
Sponsors
Study design
Masking description
Sequentially generated numbers were placed in opaque envelopes until the intervention was conducted and each participant was asked to select an envelope that determine which group of intervention was assumed
Intervention model description
The trial design is a prospective, parallel, randomized with an allocation ratio (1:1), double-blinded, single-center clinical trial
Eligibility
Inclusion criteria
* mandibular premolars * single rooted * single canalled * necrotic pulps * asymptomatic apical periodontitis
Exclusion criteria
* gross caries * root/crown fracture * sinus tract * swelling * intake of antibiotics within previous 3 months * pain with percussion
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| bacterial reduction | up to 1 hour | pre-instrumentation and post-instrumentation bacterial cultures to detect change in bacterial count after root canal instrumentation with the different kinematics |
| post operative pain | after the treatment visit by 24 hours | Visual analogue scale from 0-100 where 0 is the lowest and 100 is the highest |
