Streptococcus mutans serotyping, collagen-binding genes and Candida albicans in dentin carious lesions: a molecular approach.
Article in Clinical oral investigations, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThis cross-sectional study aimed to evaluate the occurrence of Streptococcus spp., Streptococcus mutans, its serotypes (c, e, f, and k), collagen-binding genes (cnm/cbm), and Candida albicans in medium deep (D2) and deep (D3) dentin carious lesions of permanent teeth. MATERIALS AND
methodsCarious dentin was collected from D2 (n = 23) and D3 (n = 24) lesions in posterior teeth from 31 individuals. DNA was extracted and analyzed using polymerase chain reaction (PCR).
resultsStreptococcus spp. exhibited a high prevalence in both D2 and D3 lesions, with a 100% occurrence rate in D3. Although S. mutans was prevalent in both lesion types, serotype distribution highlighted differences in complexity. Serotype e was the most frequently detected in D2 samples. Serotype c was absent in D2 but present in 19.0% of D3; serotype k was exclusively found in multi-serotype D3 alongside f, c, and e. The cbm gene and undetermined serotypes were detected only in D3. Candida albicans was not found in any samples, regardless of lesion depth.
conclusionDentinal lesions exhibited a complex array of S. mutans serotypes, with a notable prevalence of the genus Streptococcus and an overall S. mutans prevalence of approximately 35%. Candida albicans was absent. In addition, a high diversity of serotypes was observed, including multiple and indeterminate serotypes, along with the presence of the collagen-binding cbm gene. CLINICAL RELEVANCE: The identification of diverse Streptococcus mutans serotypes and the cbm gene in carious dentin from permanent teeth offers insights into microbial factors potentially linked to dentinal caries lesions. Additionally, the absence of Candida albicans suggests a limited role in this context.
