First visit:

The child will be asked to report to the school clinic to be screened by the dentist and/or hygienist to determine if he or she is a suitable test subject. If the parents and the child decide to participate and is accepted into the study, the family need to follow a specific set of instructions. The child will not perform or receive any oral hygiene (other than that described below).

At the beginning of the study, the child's teeth and gums will be examined to determine if they are eligible to participate in the study. The parents/tutors will agree to use only the fluoride toothpaste provided for the duration of the study and will be required to brush

their teeth daily in the school setting. There will be no restrictions regarding eating habits. A clinical score will be made to assess the level of caries, gingivitis and plaque level of all teeth and will be recorded on the evaluation forms. Questionnaires will be completed, and the child will be provided with a medium soft-bristled toothbrush and a tube of household toothpaste. Supervised brushing will be performed by asking the child to coat the

toothbrush head with their assigned toothpaste and brush their teeth for two (2) minutes. Subsequently, the child may receive a topical application of fluoride varnish depending on which group they belong to in this clinical trial.

The participants and their family will be asked if they want to participate in the

teleconsultation program where they will have access to an information platform with sessions to connect with a professional to obtain oral health guidance.
