Abstract

Background: Dental caries remains a significant global health problem. One of the fundamental mechanisms underlying the development and progression of dental caries is the dynamic process of demineralisation/remineralisation. In vitro models have played a critical role in advancing our understanding of this process and identifying potential interventions to prevent or arrest dental caries. This literature review aims to provide a structured oversight of in vitro mineralisation models which have been used to study the tooth demineralisation/remineralisation process. Methods: Publications from 2019 to 2023 were screened to identify articles reporting the use of in vitro models to study the demineralisation/remineralisation of tooth caries. The included studies were methodologically assessed for their information on (i) substrate, (ii) lesion formation, and (iii) mineralisation models. Results: The most reported substrates used in the studies were human teeth along with bovine incisors. Acetic/lactic buffers were the most common solutions to induce caries lesions. pH cycling was the most frequently used mineralisation model for simulating the daily change within the oral environment. This review discussed the advantages and limitations of various approaches. Conclusions: Standardisation of in vitro mineralisation models is crucial for enabling effective comparison between studies and advancing caries research.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • In vitro models of enamel and dentin repair do not fully reproduce the complex oral environment, including masticatory loading, salivary flow, dietary acid challenge, enzymatic degradation, and dynamic plaque biofilm formation.

    “These models are useful for demonstrating mineral nucleation, tubule occlusion, and interfacial bonding mechanisms, but they do not fully reproduce the complex oral environment, including masticatory loading, salivary flow, dietary acid challenge, enzymatic degradation, and dynamic plaque biofilm formation.38”

    From Polydopamine-Based Biomaterials in Oral Medicine: Applications, Mechanisms, and Translational Challenges (2026) · cites this paper as [38]

    Section 3.3 (page unavailable) says in vitro models cannot fully replicate intraoral conditions or the oral cavity’s microbiological diversity. It also discusses limitations in simulating saliva, acid exposure, and natural plaque. The cited passages do not establish the specific limitations of masticatory loading or enzymatic degradation, or the sentence’s claims about demonstrating tubule occlusion and interfacial bonding mechanisms.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
