Such restorations increase health care costs for patients and health care systems, and submit patients and their teeth to the ongoing re-restoration cycle over their lifetime, which may compromise long-term tooth survival.
Individual factors such as case history, age and probability of disease activity must be considered in all decisions concerning preventive and restorative care.
Visual and Tactile Diagnosis To ensure that maximum information is obtained during a visual examination, the teeth should be clean, completely dry and well illuminated. Even so, in vitro visual examination of macroscopically intact occlusal surfaces in an effort to detect caries generally has limited sensitivity i. Fissure morphology and discolouration black or brown are unreliable for definitive diagnosis of caries.
Other studies have also found that the presence of stain is not necessarily indicative of caries. The advisability of applying pressure with a sharp explorer has been called into question, particularly in Europe and Scandinavia, because of documented damage to surface integrity and possible implantation of organisms, both of which may increase lesion susceptibility.
The presence of visible cavitation of the enamel surface is, in most cases, synonymous with dentinal involvement. When definite cavitation is present, the question generally becomes not if, but how far, the carious process has penetrated into the dentin. Visual and tactile methods alone, in the absence of cavitation, generally have relatively poor diagnostic capability for occlusal surfaces under general practice conditions. Radiographic Diagnosis The sensitivity of visual inspection can be augmented with radiography.
Findings on bite-wing radiographs are useful indicators of dentinal decay on occlusal surfaces, and it is well recognized that the prevalence of occlusal caries may be underestimated without such imaging. Combined Visual and Radiographic Diagnosis An investigation of the validity of diagnosis by means of optimal bite-wing radiography combined with careful visual clinical examination has shown that the majority of carious lesions and nearly all sound teeth can be correctly identified.
Some diagnostic uncertainty is inherent in health care, and optimal patient care decisions should take into account all patient factors, including the probability of disease and the relative risks of delaying treatment versus undertaking unnecessary operative intervention.
Conclusions Accurate diagnosis of occlusal dentinal caries is challenging unless cavitation or radiographic evidence is present. As radiographs tend to reveal only significant caries, there is a need for diagnostic methods that can more accurately detect dentinal involvement at an earlier stage. The accurate diagnosis of the presence or absence of disease is paramount for appropriate care. More precise methods for definitive diagnosis of lesion presence, activity and size would significantly improve caries management decisions with respect to operative intervention or preventive care.
The function of KI is to remove any free silver ions beyond the affected site. Another important role of the KI is in the prevention of staining beyond the treatment zone such as transferring to aesthetic materials. SDF should not be placed on exposed pulps. Studies have shown that silver diamine fluoride conveys more effective protection against decay in other teeth than fluoride varnish with reduced overall fluoride exposure.
Desensitising indication is for use on sound tooth structure.

Riva Star may cause some discoloration if used on carious lesions. The FDA clearance only covers the use of this product as a desensitizing agent. Reapplication of SDF controls caries and treat dentinal hypersensitivity and is recommended every six 6 to twelve 12 months. Anterior teeth have higher rates of arrest than posterior teeth. Therefore, follow-up for evaluation of caries arrest is advisable.
Ask doctor in which clinical situation did he use it for? If there was a layer of plaque, removing the plaque should remove the stain. If there is still staining after removing the plaque, then there areearly stages of carious lesions. This is good because it highlighted a not detectible problem for the doctor.
Darkening of decayed and demineralized sites occurs as the lesion arrests. Non-lesioned tooth structure does not stain with the application of silver diammine fluoride. Similar to the treatment of eroded and hypersensitive dentin, the treated area can be restored using glass ionomer or with a sandwich restoration of both glass ionomer and composite. Riva Star should not be diluted in an attempt to reduce discoloration.
Studies have shown that diluted solutions may not be effective for caries arrest. Ionic silver adsorbs onto almost any protein surface and is especially tenaciously bound to denatured proteins.

This accounts for the specificity to carious collagen over normal collagen, but both will stain. The differentiator between these stains is that with SDF use intrinsic pigmentation of a carious lesion occurs and surface protein staining occurs primarily on healthy tissue.
Operation intestin pour maigrir, the blackened lesion retains its dark colour, and is most likely the reason the antimicrobial effect is long-lasting applying a saturated solution of potassium iodide KI immediately after the application of silver fluoride, staining of the dentin caries lesion can be minimized while the caries arrest effect of silver fluoride is not affected.
It would be a win-win situation if KI can prevent the staining associated with SDF without reducing its effectiveness in arresting caries. For the site-specific control of hypersensitivity, the technique to apply Riva Star is similar to that of fluoride varnish. SDF is not for generalized or full mouth applications.
Read the package insert for full application and precaution instructions. Practitioners have shared success treating interproximal lesions using tufted or sponged floss soaked with silver diammine fluoride, then pulled into the contact point and left for 60 seconds.
Additionally, some dry interproximal sites will wick SDF into the contact point from the micro brush applicators without the need for this floss technique. It is not recommended to light cure after an application of Riva Star. Light curing causes the silver to oxidize before allowing it to fully penetrate the tooth and it might cause staining. However, if you are placing a restoration on top of the Riva Star treated surface at the same appointment, wait at least 60 seconds to allow Step 1 to penetrate the lesion.
Applying a saturated solution of potassium iodide KI immediately after the application of silver fluoride, staining of the dentin caries lesion can be minimized. It is a win-win situation if KI can prevent the staining associated with SDF without reducing its effectiveness.
Silver and fluoride penetrate about 25 microns into healthy enamel and microns into healthy dentin without discoloration. The fluoride creates calcium fluoride and fluorapatite while silver binds with phosphates and protein structures in the tooth. There are no postoperative limitations. Patients may eat or drink immediately.
Patients may brush their teeth with fluoridated toothpaste on their regular schedule. A diverse group of parents 98 mothers and 22 fathers were surveyed. In the absence of behavioural barriers to conventional restorative treatments At the extreme, when provided the option of general anaesthesia, acceptance of SDF application increased to Socioeconomic status did impact acceptance of treatment. This study enrolled 32 pre-cooperative children aged years with active caries lesions in primary teeth.
Teeth were treated with SDF and children were recalled at two weeks assess colour, hardness, pain and a parent survey were conducted on ease, taste, discoloration and painlessness and at 3 months assess colour, hardness and pain. Survey results showed:. SDSF treatment. The use of potassium iodide KI can be used when silver diammine fluoride SDF is used on a prepared tooth cavity during a restorative procedure in an attempt to limit silver oxides from shadowing through restorative materials.
When restoring with composites it is recommended to first line cavity with Conventional GIC or use RMGIC bonding agent such as Riva Bond LC Prior to placement, ensure that the cavity is washed out with copious amounts of water or follow the etching protocols.
KI binds the silver portion of SDF forming a white precipitate of silver iodide. Repetitive, applications of KI are used to scrub, wash, rinse and repeat on cavity floors and walls to remove the free silver.
Studies have shown that there is a protective effect to the site of the application of silver diammine fluoride and a halo effect for the entire mouth. Yes, if Riva Star is used during a diagnostic appointment to arrest active disease, during the restorative visit the treated site can be evaluated for caries arrest providing you and the patient several options. You could choose to 1 reapply Riva Star, 2 simply leave the site as is, 3 cover the site without anaesthetics or excavation or finally 4 excavate the site and place a restoration.
Contact to skin may cause irritation or burn and may cause temporary skin discoloration.
With discoloration, the effect is not immediate, rather it will be noticed within hours. The speed of discoloration is accelerated with light contact.
Flush with running water an eschar may form on soft tissue, this should disappear within hours. Patients should be protected with bibs and safety glasses as in any clinical procedure. If you believe you have touched the applicator to the skin of a patient, it is good to advise them of possible temporary discoloration, and to wash or wipe the surface with water.
Take care to protect soft tissue with petroleum jelly or cocoa butter when an application is adjacent to gingival tissue root caries, treatment of restoration margins. Light blanching is also possible from prolonged direct contact, but has been reported to be minor and resolves within days.
Furthermore, KI also has anti-microbial properties. However, it is available for sale separately. However, Riva Star is only applied site-specifically on carious lesions or high-risk sites such as non-sealed occlusal surfaces or interproximal areas where incipient lesions are suspected. Care should be taken to isolate each cleaned application site with cotton rolls.
Many clinicians apply SDF site specifically and then apply a fluoride varnish generally. In some cases, this can help keep SDF in contact with the treatment site in patients that cannot sit for the recommended 1-minute soaking period. The darkening of the lesion occurs over 24 hours and may increase over a week.
Caries definition english
Re-examination of the lesion and reapplication of SDF may be warranted to ensure caries arrest. Reapply SDF at regular recalls until the tooth is restored or exfoliates, every months is recommended. IFU states min of 1 week between applications. Desensitizing agents have been shown to be protective of the pulp when placed on crown preparations to reduce dentin permeability. Riva Star, a tooth desensitizer, has been shown to be safe to the pulp when placed on exposed dentin.
In addition, studies have shown desensitization and efficacy in treating softened dentin before placing direct restorations. Usually the tooth is first treated with silver diammine fluoride. This provides the benefit of sealing tubules plus the antimicrobial benefits of both silver and fluoride. It is a win-win situation if KI can prevent the staining associated with SDF without reducing its effectiveness in arresting caries.
The research supporting reapplication of SDF is specific to cases where the lesion is left open without placement of a restoration. Reapplication has shown to be more effective in high risk groups. Riva Star is ideal for use on patients where more complex treatment may be difficult. An example of this is in paediatric use where caries progression can be stopped with the use of Riva Star. Since primary teeth will eventually be exfoliated, placing a restorative is not always required.
Riva Star can be used to immediately prevent further progression of caries, with the idea of restoring later i. Allow material to come to room temperature before use to avoid applying cold material on teeth.
For transport purposes, Riva Star can be stored at room temperature up to 1 week. Do not apply Riva Star on pregnant or lactating women.
Neither do not repeat treatment on pregnant or lactating women. Hard surfaces: Immediately apply household bleach sodium hypochlorite then wipe off with water. For stubborn stains, saturate a paper napkin with household bleach and place over affected area. Leave overnight and mop up with water. The use of Riva Star results in a reduced likelihood of black staining compared to that associated with the use of traditional SDF treatments. It is vital that the IFU is followed correctly to ensure application techniques are performed correctly to reduce the likelihood of staining.
Naturally arrested caries typically presents with a brown colour, this is also true for those arrested with Riva Star. This would prove useful to dentists hoping to use the benefits of silver diammine fluoride on surfaces adjacent to these materials, but who are worried about aesthetics.
Arrested lesions look like a lesion scar on radiographs.
