1 · What the graph read from it

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

aimTo assess the effect of occlusal reduction on postoperative pain following two visits root canal treatment in posterior mandibular teeth with symptomatic irreversible pulpitis and symptomatic apical periodontitis in a randomized clinical trial. METHODOLOGY: This trial was conducted in the outpatient clinic of the Endodontic Department of the Faculty of Oral and Dental Medicine, Cairo University in Egypt. Forty-four-patients diagnosed with symptomatic irreversible pulpitis and symptomatic apical periodontitis were randomly assigned into two equal groups. The occlusal surfaces of teeth in the intervention group were reduced; whilst those assigned to the control group were left intact. Canal instrumentation was completed in the first visit using Revo-S rotary nickel-titanium files, and pain intensity was assessed using a visual analogue scale (VAS) at 6, 12, 24 and 48 h. Canal filling was completed 7 days later, and pain intensity was assessed at 6 and 12 h. A placebo was given and analgesics were prescribed to be administered in case of severe postoperative pain. Data were analysed using Independent t-test, chi-square and Fisher Exact tests.

resultsThe mean pain scores within the two groups were associated with a significant continuous decrease over time. Following both instrumentation and canal filling, the mean pain scores in the intervention group were lower than those in the control group at all follow-up periods and this difference was only significant at 12 h (P = 0.021 and P = 0.015, respectively).

conclusionsOcclusal reduction reduced levels of postoperative pain in posterior mandibular teeth with symptomatic pulpitis and apical periodontitis only 12 h following both canal preparation and root filling.
