Abstract Aim: The aim of the present study is to compare the effect of using rotary Neoniti GPS glide path file in comparison to manual stainless-steel K-files on post-obturation pain, in asymptomatic non-vital mandibular molars treated in a single visit. Methods: Thirty necrotic asymptomatic mandibular permanent molars were recruited for the study and were randomly allocated into two equal groups (n=15). In the control group, glide path preparation was achieved using manual stainless-steel K-files (#10, 15) in a “feed it in and pull motion” according to Ruddle’s technique. In the experimental group a glide path was created using Neoniti GPS path file operated in continuous rotation. Standardized cleaning and shaping procedures were performed in both groups using the ProTaper Next system and (5.25%) NaOCl. A modified single cone technique was utilized for canal obturation and was sealed with an epoxy resin sealer. Cases were treated by a single operator and were completed in a single visit. Patients were asked to rate their pain level using a modified Visual Analogue Scale (VAS) chart numbered from (0-10) at 6, 12, 24, 48 and 72 hours post-treatment. Demographic data and VAS scores were collected from all patients and were statistically analysed.Results: Compared to the control group, rotary Neoniti GPS for glide path preparation resulted in significantly less post-operative pain incidence at 6 hours (p= 0.039) and was associated with significantly less post-operative pain levels at 12 hours (p=0.047). No other significant difference was found between the two groups at 24, 48 and 72 hours. No severe pain nor flare-up occurrence was recorded. No patient reported analgesic intake. Conclusions: Glide path preparation using Neoniti GPS rotary file can decrease postoperative pain incidence after 6 hours and reduce pain severity after 12 hours, when compared to manual glide path preparation using stainless-steel K-files. Both glide path preparation techniques did not result in severe pain nor flare-up occurrence. |
