“…Silver ions in the SDF solution can blacken the tooth structure. It is suggested that the KI solution can react with SDF to form a bright yellow solid compound (silver iodide) [30], and this reaction could reduce the excess free silver ions which result in the black staining [27]. Although the bright yellow precipitates can be seen after the application of KI, the staining of tooth surfaces could still be detected in SDF + KI treatment group in this study.…”

“…In this study, SDF + KI treatment led to discolouration of tooth surfaces although the intensity of the discolouration was less than that of SDF treatment. One possible explanation may be that the amount of the applied KI solution was not sufficient to lead to an excess of free silver ions remaining [30]. Besides, silver iodide is considered to be highly photosensitive which can dissociate into metallic silver and iodine by exposure to light.…”

This study investigated the effect of silver diamine fluoride (SDF) and potassium iodide (KI) treatment on secondary caries prevention and tooth discolouration in glass ionomer cement (GIC) restoration. Cervical GIC restorations were done on 30 premolars with: Group 1, SDF + KI; Group 2, SDF (positive control); Group 3, no treatment (negative control). After cariogenic biofilm challenge, the demineralisation of dentine adjacent to the restoration was evaluated using micro-computed tomography (micro-CT) and Fourier transform infrared (FTIR) spectroscopy. The colour of dentine adjacent to the restoration was assessed using CIELAB system at different time points. Total colour change (∆E) was calculated and was visible if ∆E > 3.7. Micro-CT showed the outer lesion depths for Groups 1, 2 and 3 were 91 ± 7 µm, 80 ± 7 µm and 119 ± 8 µm, respectively (p < 0.001; Group 2 < Group 1 < Group 3). FTIR found that there was a significant difference in amide I-to-hydrogen phosphate ratio among the three groups (p < 0.001; Group 2 < Group 1 < Group 3). ∆E of Groups 1, 2 and 3 after biofilm challenge were 22.5 ± 4.9, 70.2 ± 8.3 and 2.9 ± 0.9, respectively (p < 0.001; Group 3 < Group 1 < Group 2). SDF + KI treatment reduced secondary caries formation on GIC restoration, but it was not as effective as SDF treatment alone. Moreover, a perceptible staining on the restoration margin was observed, but the intensity of discolouration was less than that with solely SDF treatment.

“…This material has the added advantage of only requiring a single professional application annually, and thus reduces the burden of care in vulnerable dependent patients. In a randomised clinical trial with a 30‐month observation period, Li et al demonstrated that approximately 90% of active root carious lesions were arrested with an annual application of SDF varnish …”

Minimal intervention dentistry for partially dentate older adults

Background Chronic dental and oral diseases, such as dental caries and periodontal disease, continue to be a significant health problem among older adults. Given the rapidly changing profile of the ageing population, and their complex health needs, there is a need to develop new evidence‐based approaches to oral health care. Recently, care philosophies have been developed that take a minimally invasive, functionally oriented, approach to oral health care with a focus on providing a reduced, but healthy, natural dentition which can be maintained with support of better oral hygiene. Method A review of the literature concerning use of minimal intervention dentistry (MID) to manage caries and toothloss in partially dentate older adults was undertaken. Results A variety of chemotherapeutic agents are available to prevent development of root caries and/or arrest root caries lesions, with professionally applied solutions (ie 22 500 NaF, 38% SDF or 40% CHX) every 3 to 6 months demonstrating best outcomes. Application of 38% SDF annually in high‐risk, institutionalised older adults is effective in arresting root caries. Atraumatic restorative treatment can be used successfully to manage active carious lesions and limit the removal of natural tooth tissue. Finally, functionally oriented treatment planning to manage partial toothloss is successful in terms of quality of life impact and cost‐effectiveness. Conclusion Available evidence is somewhat limited and more long‐term studies are need. However, currently available evidence suggests that minimal intervention dentistry can be predictable and cost‐effective in older adults.

Randomized clinical trial on arresting dental root caries through silver diammine fluoride applications in community-dwelling elders

Abstract: In a water fluoridated area, annual application of SDF solution or SDF/KI solution can arrest dental root caries in elders. In the long term, application of KI does not reduce the blackening of arrested caries lesions caused by SDF.
