Caries arrest and lesion appearance using two different silver fluoride therapies on primary teeth with and without potassium iodide: 12‐month results

Abstract

Background: Globally, has been an increase in the use of silver fluoride products to arrest carious lesions and a variety of products are available.Objectives: To examine differences in caries arrest and lesion colour of primary tooth carious lesions.Material and Methods: A four-armed, parallel-design cluster-randomised controlled trial which investigated four protocols for caries arrest at 6m and 12m. Children in Group 1 and Group 2 received Rivastar Silver Diammine Fluoride (SDF), and children in Group 3 and Group 4 received a stabilised aqueous silver fluoride solution (AgF).Children in Group 2 and Group 4 received an additional application of KI immediately after the fluoride. Differences in caries arrest and lesion appearance were examined at 6m and 12m using two level logistic regression modelling. Results:The arrest rate varied by group membership; group 1 and group 3 had higher arrest rates (77.3% and 75.3% respectively) than group 2 and group 4 (65.4% and 51.2% respectively). The use of KI was also associated with lower odds of arrest (12m OR 0.25; CI 0.19, 0.34) and higher odds of avoiding black discolouration (12m OR 6.08; 2.36, 15.67).Conclusions: Globally, has been an increase in the use of silver fluoride products to arrest carious lesions and a variety of products are available. This study demonstrated that both AgF and SDF can effectively arrest carious lesions on primary teeth. The use of KI is associated with poorer caries control but better aesthetic outcomes.

School Based Tooth Brushing and Annual Silver Diammine Fluoride Application as a Highest Priority Package for Achieving Universal Oral Health Care for Cambodian Children

“…The arrest rate achieved by the SDF application in School 1 is consistent with both published reports on caries arrest globally and from within Cambodia [ 10 – 14 ]. Other studies have reported arrest rates of around 50–70% with an annual application of SDF [ 15 ].…”

A Review of the Protocol of SDF Therapy for Arresting Caries

“…A clinical trial found that the application of potassium iodide was associated with better aesthetic outcomes but poorer caries control compared with SDF application only. 26 A laboratory study showed that potassium iodide application could reduce the intensity of staining in a dose-dependent manner. 27 However, no significant difference was found 14 days after SDF application.…”

Effectiveness of Silver Diamine Fluoride in Arresting Caries in Primary and Early Mixed Dentition: A Systematic Review

“…Many studies have reported different solutions to overcome this disadvantage and decreasing the staining of the treated teeth such as the application of potassium iodide following the application of SDF [ 23 , 24 , 25 , 26 ]. In terms of parental acceptance, several studies have reported that SDF black staining of teeth was accepted by parents in posterior compared to anterior teeth in addition to other reasons as the child’s cooperation, socioeconomic status, and the need of using sedation or referral to general anesthesia to receive dental treatment [ 12 , 16 , 20 ].…”
