The Photobiomodulation effect of 980 nm Diode Laser on Patients with Xerostomia.
Article in Lasers in medical science, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
purposeXerostomia is not a disease in itself. This condition is associated with systemic diseases, medication use, and radiotherapy. Oral and general health suffer when the salivary gland´s function is reduced. The effectiveness of therapeutic methods in resolving this issue thus far has been inadequate. This study aimed to determine the photobiomodulation (PBM) effect of a 980 nm laser on xerostomia.
methodsA quasi-experimental study was carried out using a 980 nm diode laser on 28 patients with xerostomia. A diode laser (980 nm) was used extortionally over the submandibular glands and parotids and it was used internally in the sublingual glands. The laser beam (extrorally 6 J, 300mW, 20 s, and introrally 4 J, 200mW, 20 s) was applied bilaterally every other day for 10 sessions. It should be noted that 8 points of the parotid, 2 points of the submandibular glands, and 2 points of the sublingual glands were irradiated. The saliva was collected each session using the Navazesh technique, 5 min before and after PBM. The Wilcoxon test was used to study the effect of laser therapy on saliva flow rate (volume and weight). The P < 0.05 level was considered a significant level.
resultsThe volume (P < 0.0001) and the weight (P < 0.0001) of the saliva were increased by using a 980 nm diode laser. While, in smokers and diabetic patients with hypertension, no significant difference was observed in either saliva volume (P = 0.593, P = 0.092) or weight (P = 0.785, P = 0.089).
conclusionIn this study, the volume and weight of the unstimulated saliva in most patients with xerostomia increased with using PBM.
