Effectiveness of Laser-activated Irrigation Modalities on Intracanal Bacterial Elimination and Apical Extrusion.
Article in European endodontic journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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.
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
objectiveThis study aimed to compare photon-induced photoacoustic streaming (PIPS) and diode laser with passive ultrasonic irrigation (PUI) in activating intracanal irrigants for bacterial elimination from the root canal and apical extrusion.
methodsSixty extracted single-canal human teeth were chemo-mechanically prepared and placed in 3 ml glass vials with sterile 0.9 % sodium chloride solution. The root canals were inoculated with Enterococcus faecalis and incubated for 24 hours at 37°C. The samples were divided into three experimental groups (PIPS, diode laser, and PUI) and a control group (n=15 each). The experimental groups had root canals filled with saline and activated according to the manufacturer's instructions, while the control group received saline without activation. Bacterial samples were collected from the canals and outside the apex for quantification, cultured on nutrient agar for 24 hours at 37°C, and counted as colony-forming units. Mean values were compared using one-way ANOVA and Bonferroni tests at 5 % significance.
resultsAll activation protocols significantly eliminated intracanal E. faecalis compared to the negative control group (p<0.05). PUI and the diode lasers were significantly more effective than PIPS (p<0.05). Extruded bacteria were higher in PUI than in PIPS and diode lasers.
conclusionWithin the limitations of this study, the tested techniques extruded bacteria and did not completely eliminate intracanal bacteria. The diode laser showed the best bacterial elimination and extrusion outcome. (EEJ-2024-07-112).
