Impact of root canal shaping using TruNatomy on postoperative pain and operative torque generation: a randomized clinical trial.
Trial report in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04616469 (Evaluation of the Effect of Root Canal Shaping With TruNatomy on Postoperative Pain and Operative Torque Generated During Instrumentation), which is not on this map.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundTruNatomy instruments promises a more conservative alternative to conventionally used instruments. They are claimed by the manufacture to decrease the amount of debris extrusion as well as the torque generated during instrumentation, potentially resulting in lower post-operative discomfort and a safer more convenient experience for the patient and clinician.
aimTo compare the effect of canal shaping using TruNatomy (TN) rotary system to RaCe (RC) rotary system on post-operative pain in necrotic maxillary bi-rooted premolars, while simultaneously inspecting the real-time dynamic forces produced during instrumentation.
methodsIn this parallel group superiority trial, following power calculation, 40 patients diagnosed with pulp necrosis in asymptomatic bi-rooted maxillary premolars were recruited and randomly allocated into two equal groups (n = 20) according to the instrumentation system used. Treatment was completed in a one visit for all cases. Pain levels were recorded immediately before RCT and at 6,12,24,48, 72 h, and 1-week post RCT using mVAS. The number of analgesics taken if any was also recorded. Operative torque generated during root canal preparation as well as the time taken for the instrument to reach the working length were simultaneously recorded during instrumentation. Outcome data was statistically analyzed using Shapiro Wilk test, independent t test, Mann-Whitney U, Chi square, Fisher exact tests, spearman's correlation coefficient. Significance level (α) was set at 0.05.
resultsThere was no statistically significant difference between pain scores in the test groups at all time points measured (P > .05). No significant different was also recorded in terms of number of analgesics taken (P > .05). Mean torque, average peak torque and maximum torque values showed no statistically significant difference as well, however the instrumentation time was significantly shorter for the TN Group (P < .05). A moderate significant positive correlation was found between the instrumentation time and generated operative torque.
conclusionTN and RC rotary instruments resulted in similar and acceptable levels of post-operative pain in cases of asymptomatic necrotic teeth. However, TN rotary system combined torque and instrumentation time values suggest an overall higher cutting efficiency and potentially a better safety profile as compared to RC rotary system.
