THE EFFECT OF GLIDE PATH ESTABLISHMENT ON STRESS GENERATION DURING INSTRUMENTATION: AN ACOUSTIC ANALYSIS

Özet

Aim: This acoustic analysis is a study aimed at evaluating the effect of glide path preparation on sound wave propagation due to stress in resin blocks during root canal preparation. Methods: Endo training resin blocks with J-shaped canals were randomly divided into two groups according to glide path establishment (with or without) (n:12). For the glide path establishment group, the glide path was prepared using WaveOne Gold Glider. All samples were shaped with WaveOne Gold. During the instrumentation with WaveOne Gold, sound signal levels were recorded on a computer using a piezoelectric probe. The data were analyzed statistically using Mann-Whitney U tests at a significance level of P < .05. Results: Sound signal levels were significantly different between groups (P < .05). The signal levels in WaveOne Gold with the glide path group were lower than in the WaveOne Gold without a glide path group (P < .05). Conclusion: Our results show that creating a glide path can decrease the amount of stress during shaping with WaveOne Gold. The establishment of a glide path before root canal preparation appears to be appropriate for safely shaping the canal.
