Moving toward new clinical solutions will require broader perspectives; to this end, we propose key directions to advance the translational potential of caries microbiome research. We present a perspective that connects ecological theory, molecular evidence, and clinical implications through three central topics: (1) microbial composition, (2) microbial function, and (3) individual-level characteristics.</p><p><strong>Summary: </strong>From a compositional perspective, caries microbiome research should move beyond the search for bacterial culprits and instead consider the broader microbial ecosystem, including low-abundance and nonbacterial members (such as archaea). Within this framework, microbial taxa and functions should not be viewed as inherently \"good\" or \"bad,\" but rather as context-dependent components of a dynamic ecosystem shaped by sustained environmental pressures. Functionally, the recurrent enrichment of pathways related to carbohydrate metabolism, sugar transport, and acid production likely reflects microbial adaptation to persistent sugar exposure rather than intrinsic virulence traits. This perspective suggests that progress in caries research depends on moving beyond disease-centered models toward understanding how microbial stability preserves oral health. At the individual level, individuals with previous caries experience may retain disease-associated microbial or functional signatures during remission, a phenomenon referred to here as a microbiological dysbiosis scar. This ecological memory may help explain why past caries experience remains one of the strongest predictors of future lesions and highlights the importance of incorporating individual history into the design and interpretation of caries microbiome studies. Integrating detailed clinical metadata with advanced bioinformatic approaches, including artificial intelligence, will be essential for establishing meaningful biological links.</p><p><strong>Key messages: </strong>Progress in caries microbiome research depends on refining study design across microbial composition, functional, and individual levels. Strengthening the resilience of the oral microbiome rather than eliminating specific pathogens or the microbiome should be the central goal of caries microbiology.

Poisson regression was performed to estimate prevalence ratios (PRs) and 95% confidence intervals (95% CIs).</p><p><strong>Results: </strong>A total of 286 pairs of children and mothers/grandmothers were evaluated for the intergenerational sample (1982 and 1993 cohorts), and 3,633 mothers and children for the intragenerational sample (2015 cohort). In the intergenerational analysis, there was a reduction of about 10 percentage points in the prevalence of untreated caries in children from families that experienced upward/downward income mobility compared to children whose generations remained with lower income. In the intragenerational analysis, children belonging to the ascending/descending economic mobility groups had twice the prevalence of untreated dental caries compared to those always with higher salaries (PR 2.04; 95% CI 1.52-2.71 and PR 2.07; 95% CI 1.56-2.74, respectively).</p><p><strong>Conclusion: </strong>Findings demonstrate an association between untreated dental caries in children and family socioeconomic status, including their mothers' income/education mobility. Thus, intervening in early childhood socioeconomic conditions is needed to improve children's oral health.</p>","PeriodicalId":9620,"journal":{"name":"Caries Research","volume":" ","pages":"54-64"},"PeriodicalIF":2.5,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144149316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
