Dental biofilm in children with normal weight, overweight and obesity: a pilot study.
Article in Acta odontologica latinoamericana : AOL, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Microorganisms attached to surfaces form intricate colonies known as biofilms. Dental plaque is the biofilm formed on the tooth surface, including the gingival sulcus. Plaque staining makes it easier to see which areas need more brushing time, and which have higher risk of periodontal disease or caries. Dental plaque is largely influenced by diet, becoming more and more dependent on diet related carbohydrates as it ages. Inadequate dental care and bad eating habits are frequently associated with the presence of visible bacterial plaque.
aimThe aim of this study is to evaluate the percentage of dental plaque according to body mass index (BMI) and to identify whether the plaque is newly deposited, mature or acidified. MATERIALS AND
methodTwenty-five patients from the Pediatric Dentistry Clinics at the University of Guadalajara were evaluated. The percentage and type of plaque were identified using a disclosing gel. The percentage of plaque was compared among children with normal weight, overweight and obesity.
results14 children were normal weight, six were overweight, four were obese, and one was underweight. Average percentage of total plaque was 70.92%. The most predominant plaque was newly deposited (pink staining), followed by mature plaque (purple staining), and a lower percentage of acidified plaque (light blue staining).
conclusionsThe high percentage of plaque indicates lack or inefficacy of tooth brushing, highlighting the importance of using plaque disclosure for diagnostic and educational purposes for children and parents.
