Brushing teeth combined with toothpaste is influential in maintaining
dental and oral hygiene, especially for children still developing.
Toothpaste contains several active ingredients, including detergent in
the form of Sodium Lauryl Sulfate (SLS). This study aims to determine
whether or not using children's toothpaste that contains SLS and does
not contain SLS on the enamel surface roughness. An experimental
laboratory study was conducted on twenty primary incisors divided into
two groups of treatment samples to be brushed using toothpaste
containing SLS and not SLS. Toothbrushing treatment was carried out for 30 days in the morning and evening with the assumption that the
accumulated time for 6 minutes was the same as the time to brush your
teeth in 1 day, 2x brushing your teeth in the morning and at night. The
tooth enamel surface roughness was measured before and after treatment in the middle 1/3 of the labial surface using a Mituyo SJ 301
profilometer. Statistical analysis using the Dependent t-Test showed that
the P-value of the enamel surface roughness variable was less than 0.05 (P-value
