Background: Evidence-based noninvasive caries therapies for initial caries lesions are available in the United States. Fundamental differences between noninvasive therapies and the traditional surgical dental approach warrant a study of the financial scalability., Methods: The financial costs and benefits of fee-for-service clinics and payors were compared across 11 scenarios simulating the treatment of 1,000 initial caries lesions during a 3-year period. The scenarios included varying combinations of noninvasive therapies (that is, silver diamine fluoride, self-assembling peptide P 11 -4, and glass ionomer therapeutic sealants), no treatment, and various rates of 1- through 3-surface restorations to an estimated 2022 practice model. We used a decision tree microsimulation model for deterministic and probabilistic sensitivity analyses. We derived assumptions from an initial lesion and noninvasive therapy-focused cohort study with operations data from 16 sites accepting Medicaid in Alabama as a case study and clinical data from all 92 sites., Results: In comparison with the 2022 practice model assumed for this study, scenarios that produce mutually beneficial results for payors' savings and clinics' net profits and profit margins include self-assembling peptide P 11 -4, silver diamine fluoride on nonesthetic surfaces, and a mix of 3 noninvasive therapies. When considering the limited resources of chair and clinician time, the same scenarios, as well as silver diamine fluoride with restorations, emerged with substantially higher clinic net profit., Conclusions: Hypothetical scenarios that include noninvasive therapies and minimize restorations achieve improved outcomes for all parties., Practical Implications: Payors and clinicians should explore and implement noninvasive caries therapies to improve oral health for all.

Background: Simple noninvasive evidence-based interventions for caries are needed to overcome limitations in the restorative paradigm. The self-assembling peptide P 11 -4 is a noninvasive intervention that regenerates enamel in initial caries lesions., Studies Reviewed: The authors conducted a systematic review and meta-analysis on the effectiveness of the P 11 -4 products Curodont Repair (Credentis; now manufactured by vVARDIS) (CR) and Curodont Repair Fluoride Plus (Credentis; now manufactured by vVARDIS) on initial caries lesions. Primary outcomes were lesion progression after 24 months, caries arrest, and cavitation. Secondary outcomes were changes in merged International Caries Detection and Assessment System score categories, quantitative light-induced fluorescence (QLF; Inspektor Research System), esthetic appearance, and lesion size., Results: Six clinical trials met the inclusion criteria. Results of this review represent 2 primary and 2 secondary outcomes. When compared with parallel groups, use of CR likely results in a large increase in caries arrest (relative risk [RR], 1.82 [95% CI, 1.32 to 2.50]; 45% attributable risk [95% CI, 24% to 60%]; number needed to treat [NNT], 2.8) and likely decreases lesion size by a mean (SD) of 32% (28%). The evidence also suggests that use of CR results in a large reduction in cavitation (RR, 0.32 [95% CI, 0.10 to 1.06]; NNT, 6.9) and is uncertain about lowering merged International Caries Detection and Assessment System score (RR, 3.68 [95% CI, 0.42 to 32.3]; NNT, 19). No studies used Curodont Repair Fluoride Plus. No studies reported adverse esthetic changes., Practical Implications: CR likely has clinically important effects on caries arrest and decreased lesion size. Two trials had nonmasked assessors, and all trials had elevated risks of bias. The authors recommend conducting longer trials. CR is a promising treatment for initial caries lesions. The protocol for this systematic review was registered a priori with PROSPERO (304794)., (Copyright © 2023 American Dental Association. Published by Elsevier Inc. All rights reserved.)
