Antimicrobial Efficacy of Aloe Vera, Chlorhexidine, Hyaluronic Acid, and Diode Laser Against Periodontopathogenic Bacteria: A Mixed-Methods Study.

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
introductionThis study aimed to assess and compare the antibacterial properties of aloe vera, chlorhexidine (CHX), hyaluronic acid (HA), and diode lasers against periodontal pathogens across various time intervals. The goals included evaluating the effectiveness of aloe vera, CHX, HA, and a diode laser at 0.5, 1, 2, and 5 minutes against periodontal pathogenic bacteria, with a focus on determining their antimicrobial efficacy. MATERIALS AND
methodsThis mixed-methods study included 25 patients with chronic periodontitis (probing depth ≥ 5 mm at five or more sites with clinical attachment loss and ≥ 20 teeth). Subgingival plaque was collected from four quadrants per patient and randomized into four experimental groups (n = 25): 100% aloe vera gel (locally sourced, formulated with carboxymethylcellulose; Merck/MilliporeSigma, Burlington, Massachusetts, United States), 0.2% CHX mouthwash (Corsodyl; GSK plc, London, United Kingdom), 10% dilution of 0.8% high-molecular-weight HA (1.5 MDa) (Gengigel®; Ricerfarma S.r.l., Milan, Italy), and a 980 nm diode laser (Picasso; AMD Lasers, Indianapolis, Indiana, United States). In the control group (n =25), subgingival plaque was randomly collected from any quadrant. Viable colonies were counted on blood agar plates (HiMedia Laboratories Private Limited, Thane, Maharashtra, India) after 48 hours of incubation. The saline control (0.9%) (Baxter India Pvt. Ltd., Gurgaon, India) was processed similarly. Data were log-transformed and analyzed using multivariate analysis of variance (MANOVA) and Tukey's test (p < 0.05).
resultsDiode laser treatment demonstrated the highest antibacterial efficacy, achieving complete pathogen eradication within two minutes. CHX showed rapid and sustained reductions, followed by HA, with significant effects at longer exposure times. Aloe vera exhibited the lowest efficacy, with notable reductions observed after two minutes. Saline did not exhibit antimicrobial effects. Treatment, time, and their interactions significantly influenced bacterial reduction (p < 0.001).
conclusionThe 980 nm diode laser exhibited superior antibacterial efficacy for acute periodontal interventions, followed by CHX, HA, and aloe vera. These findings support the tailored use of adjunctive therapies based on exposure time and clinical needs for chronic periodontitis management.
