Abstract
SDF has the potential to be a therapy that helps lots of kids. SDF can stop dentine carious lesions in primary teeth, according to the WHO 2016 report on Public Health Interventions against ECC and the American Academy of Pediatric Dentistry’s (AAPD) published guidelines for its use. It advises using it as an alternate method for tertiary prevention in order to improve the quality of life for kids who have early childhood caries, lessen the harmful effects of caries by restoring function and lowering disease-related problems.
The present study was carried out on 48 extracted carious primary molars were included in this vitro study and assigned into two main groups (28 for microleakage test and 20 for micro tensile test). Primary molars were obtained from the outpatient’s dental clinic of Pediatric Dentistry Department, Faculty of Dentistry, Ain Shams University.
The main findings of the study revealed that: For microleakage test, the gingival readings: there was no statistically significant difference between different groups (p=0.490). The highest value was found in M2b (2.33±0.52), followed by M2a (2.14±1.07), then M1b (1.83±0.75), while the lowest value was found in M1a (1.71±0.76). And the occlusal readings, there was no statistically significant difference between different groups (p=0.982). The highest value was found in M1a (1.43±0.98), followed by M1b (1.33±1.03), then M2a (1.29±1.25), while the lowest value was found in M2b (1.17±1.33).
For micro tensile bond strength test, there was a statistically significant difference between different groups (p=0.034). The highest value was found in T2b (11.64±1.58), followed by T2a (10.46±1.80), then T1b (9.46±1.84), while the lowest value was found in T1a (8.18±1.62). Post hoc pairwise comparisons showed T2b to have significantly higher value than T2a (p<0.001).
By analyzing these results, it showed that there is no effect of silver diamine fluoride on microleakage and micro tensile bond strength of glass ionomer cement and flowable resin composite to carious primary molars.
