“EFFICACY OF GLIDE PATH PREPARATION USING A ROTARY AND A RECIPROCATING FILE SYSTEM IN MODERATELY AND SEVERELY CURVED MOLAR ROOT CANALS- A COMPARATIVE IN-VITRO STUDY”

Abstract

Aims: This study aims to compare the efficacy of reciprocating and rotary systems in achieving full working length and assess their fracture resistance in moderately and severely curved root canals.

Settings and Design: Comparative In-Vitro Study

Methods and Material: 68 freshly extracted human molars with curved root canals were selected and divided into moderately and severely curved canals (n=34). Each group was further divided into two subgroups based on the system used- the reciprocating system (WaveOne Gold Glider) and the rotary system (ProGlider) (n=17). Instrumentation was performed according to manufacturer instructions. The length of instrumentation and fracture resistance were evaluated.

Statistical analysis used: Data were documented, organized into tables, and analyzed statistically using the Chi-square test.

Results: The reciprocating system outperformed the rotary system in achieving full working length in severely curved canals (p < 0.05). However, no statistically significant difference was found between the systems in moderately curved canals. The WaveOne Gold Glider exhibited greater fracture resistance than the ProGlider in both canal curvatures (p < 0.05).

Conclusions: The WaveOne Gold Glider demonstrated superior performance in navigating severely curved root canals compared to the ProGlider. Both systems showed comparable efficacy in moderately curved canals. The WaveOne Gold Glider also exhibited greater fracture resistance, suggesting increased durability in challenging canal anatomies. These findings highlight the importance of selecting appropriate instrumentation systems based on canal anatomy to enhance clinical outcomes and reduce instrument failure risk.
