To evaluate the clinical outcomes in light of caries arrest and hypersensitivity relief following application of silver diammine fluoride and potassium iodide SDF+KI (Riva Star®, SDI Limited) on hypersensitive carious lesions (ICDAS 5) after a 3-month follow-up.

METHODS
15 children aged 2-5 years (3.58±0.95) requiring a desensitizing treatment of hypersensitive carious lesions were consecutively recruited at the Preventive and Pediatric Dentistry Department of Greifswald University/Germany. After hypersensitivity was confirmed, teeth were isolated, caries activity was clinically assessed (Bjorndal Criteria; 0-9), then SDF+KI was applied following manufacturer’s instructions. Clinical variables assessment took place at baseline and at 3 months mark after treatment. Parents assessed their children’s hypersensitivity using a Visual Analogue Scale (0-10= no – severe pain). Variables were compared between baseline and follow-up using paired t-test, Wilcoxon signed rank test and McNemar test. Only one tooth per child was analyzed.

RESULTS
Assorting the 15 participants (dmft=8.07±2.79), 9 (60%) were boys and 6 (40%) girls. From 15 (100%) active carious lesions at baseline, following 3-months, 13 (86.7%) were inactive and 2 (13.3%) remained active (p= <0.001). Regarding hypersensitivity, pain scores varied between moderate pain (scores 4 and 5) at baseline in 8 (53.3%) and 7 children (46.7%), respectively. 3-months later, 13 (86.7%) patients’ parents reported no pain, 1 (6.7%) mild pain, and 1 (6.7%) no change in pain (score 4; p=0.001).

CONCLUSIONS
SDF+KI in Riva Star® capsules had a leading effect in desensitizing and arresting caries in hypersensitive active carious primary teeth. This study was partially funded by SDI Limited. Summary
silver diammine fluoride and potassium iodide were efficient for treating hypersensitivity in carious primary teeth and showed caries arresting effect among a high caries risk population.
