Glide path enlargement of curved molar canals using HyFlex EDM glide path file versus PathFile: a comparative study of preparation time and postoperative pain

Impact of Different Glidepath Techniques on the Overall Performance of WaveOne Gold in an Artificial S-Shape Canal

OBJECTIVES

The article's aim is to test if rotary or reciprocating glide path influences the overall performance of WaveOne Gold in S-shaped canals.

METHODS

Sixty endo training blocks with an S-shape curvature were divided into three groups based on the glide path method used: no glide path; glide path preparation with ProGlider; glide path preparation with WaveOne Gold Glider. All blocks were then shaped with WaveOne Gold Primary. The time for shaping, the incidence in reaching working length and the number of pecking motions were recorded. ANOVA with Turkey's test was used, and the p-value was set to 0.05.

RESULTS

WaveOne Gold Primary reached working length faster in the control group when comparing total working times. No significant differences in the ability of the WaveOne Gold Primary to reach working length in all groups (p > 0.05). The mean number of pecking motions was higher in the control group compared to other groups.

CONCLUSIONS

No significant differences in the time needed to achieve a glide path between Proglider and WaveOne Gold Glider. WaveOne Gold Primary can shape a double curved canal faster if a glide path is present but takes less time to reach length if it is the only file used. No difference in the ability to reach working length.

Pain and Avoidance during and after Endodontic Therapy: The Role of Pain Anticipation and Self-Efficacy

Background: Pain anticipation has been identified as a predictor of pain and avoidance with respect to endodontic therapy. Self-efficacy is also key to the development and maintenance of health behaviors and achieve patient adherence to treatment. However, the role of self-efficacy has not been studied yet in endodontic treatment. Methods: This study was conducted on 101 patients who needed root canal therapy. They had to fill a questionnaire before treatment registered pain anticipation and self-efficacy; during and after treatment were registered pain intensity and avoidance. Results: Pain anticipation explained pain during (Beta = 0.51, t = 5.82, p ≤ 0.001, [0.34, 0.69]) and after treatment (Beta = 0.38, t = 4.35, p ≤ 0.001, [0.21, 0.55]). Self-efficacy did not have an influence in pain values. Pain anticipation explained avoidance during (Beta = 0.51, t = 3.60, p ≤ 0.001, [0.23, 0.80]) and after treatment (Beta = 0.62, t = 4.29, p ≤ 0.001, [0.33, 0.91]). Self-efficacy had a significant role in avoidance during treatment (Beta = 0.12, t = 2.19, p ≤ 0.03, [0.01, 0.23]) with a strong moderation relationship between pain anticipation and avoidance when self-efficacy was medium (Beta = 0.44, t = 3.24, p = 0.002, [0.17, 0.72]) or high (Beta = 0.84, t = 3.5, p ≤ 0.001, [0.37, 1.33]). Self-efficacy was not significant respect to avoidance after treatment. Conclusions: Self-efficacy is an important variable in endodontic therapy due to their moderating effect between pain anticipation and avoidance behavior during the procedure. It is necessary to improve the results of root canal therapy and reduce patient’s avoidance in order to take into account this variable.
