Outcomes
Primary outcome [1] 262296 0
prevention of lesion formation on treated surfaces this will be determined using radiographs which would be part of routine check up
Timepoint [1] 262296 0
Baseline, 6, 12, 24, 36 months
Secondary outcome [1] 273479 0
saliva profile ( the saliva profile will be measured using a Saliva Test Kit,manufactured by GC. Ask subject to spit a drop of saliva into a cup then measure its pH using a pH test strip, collect stimulated saliva by asking subject to chew on paraffin wax and spit in a cup, the volume is recorded and the buffering capacity is measured using a test trip manufactured by GC)
