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.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

purposeNon-instrumentation endodontic treatment precludes that an antibiotic paste, placed on the furcation area of primary molars, will be able to heal furcation lesions and treat an infected root canal. Thus, the aim of the study was to characterise the furcation area of primary molars using micro-CT.

methodsPrimary molars, extracted due to pathological conditions, were scanned, and after reconstruction, dentine thickness at the furcation area was measured, resorption gaps and accessory canals were quantified, and mean grey values at the furcation were compared with two other areas of root dentine in each specimen using ImageJ.

resultsTwenty-five maxillary first molars, 19 maxillary second molars, 13 mandibular first molars and 28 mandibular second molars were studied. All (n = 85; 100%) had resorption gaps, and mean dentine thickness at the furcation was 2.3 mm. Nineteen teeth (22.3%) had accessory canals, and in 16 (19.5%), these communicated the pulp chamber with the furcation. Of these, eight (42.1%) were maxillary first molars. No mandibular first molars presented accessory canals. Mean grey value of root dentine was lower (153.2 ± 18.2) than values at the furcation (157.7 ± 19.54) (Wilcoxon test, p < 0.05).

conclusionAll primary molars had resorption gaps, and in many of them, communication between the pulp chamber and the furcation area by an accessory canal was detected. Furcation areas showed higher microradiographic density values than root dentine areas.
