Parental Satisfaction of Hall Technique Versus Silver Diamine Fluoride (SDF) in the Management of Carious Primary Molars Randomized Clinical Trial

dental caries is a critical disease that affects primary teeth in early childhood. It occurs through interaction between acid-producing bacteria and carbohydrates on tooth surface. progression of caries depends on several factors such as type of diet, oral hygiene, cariogenic bacterial load and salivary flow. to control caries, the life style of a child should be improved by having healthy non-cariogenic diet and proper oral hygiene.

caries can be treated by advanced non-invasive methods such as: Hall technique and Silver diamine fluoride which are based on controlling the acidic medium of a cariogenic biofilm without removal of caries thus, arresting the progression of demineralization and restoring the function of diseased molars.

The first report on Hall Technique published in 2007 by a general dental practitioner from Aberdeen/Scotland, Dr. Norna Hall. Dr. Hall used PMCs to restore carious primary molars rather than using the standard technique through a more simplified method.

Previous studies have recommended silver diamine fluoride (SDF) to arrest early childhood caries ECC. However, no well-designed clinical trials have yet been performed to study the effect of SDF on caries prevention.

The trial is seeking the measurement of effectiveness of two modalities (Hall & SDF techniques) to achieve best acceptable treatment for caries in developing countries which have high caries index.
