NANO SILVER FLUORIDE USED IN CARIES ARREST EVALUATED WITH AND WITHOUT RESTORATION IN CHILDREN - A PROSPECTIVE STUDY

This is a prospective study to determine the compare the caries incidence and caries pattern with and without restoration after the application of Nano silver fluoride(NSF).An aseptic protocol will be carried out throughout the procedure. Clinical examination of children will be performed using plain mirror and explorer on the dental chair with optimal light. Activity of cavitated dentinal caries lesion will be assessed by visual inspection and aided by tactile detection using an explorer. Each child will be examined for carious status using International Caries Detection and Assessment System (ICDAS).

After clinical examination, subjects fulfilling the selection criteria will be randomly divided into two groups, Group A (n=20) Group B (n=20). NSF application will be carried out in both groups & GIC restoration of treated occlusal lesions in group B, dietary and oral hygiene instructions will be given to all children.

NSF application procedure is as follows:

All the study participants will be subjected to thorough oral prophylaxis, no effort would be done to remove the caries or unsupported enamel followed by cotton roll isolation and  initial cleaning of the cavity to be performed by using small cotton pellet, tooth with active caries lesion will receive two drops of NSF with an applicator tip and the same tip is applied across all the tooth surfaces & discarded after single use. Application time is 2 minutes. Excess NSF is to be removed with cotton pellet to minimize systemic ingestion.

Clinical examination of all the subject subjects will be done over a period of 6 months to ascertain any change in the dmfs index, caries pattern, retention of GIC cement, any adverse events.
