The present study aims to evaluate the effectiveness of Teleorientation in oral hygiene during Pandemic by COVID-19 in children aged 6 to 10 years, attended at the Pediatric Clinic of Forp. For this, a randomized clinical study will be carried out with the factor to be analyzed the comparison between synchronous and asynchronous teleorientation, the effectiveness of the transfer of knowledge in oral hygiene through video modeling and remote guidance. The response variables will be the assimilation of oral hygiene guidance through video modeling and synchronous guidance, the hypothesis is that educational content will have beneficial effects on children's oral health.

This is a randomized clinical trial, whose sample is composed of thirty children aged 6 to 10 years, attended between the year 2019 and the beginning of 2020. The sample will be randomly randomized into 3 groups who received guidance on toothbrushing. group 1 will be done Teleorientation of tooth brushing through video call by the Whatsapp application, in group 2 will be done Teleorientation of toothbrushing through a platform designed exclusively for teleconsultations and group 3 will receive the same in-person brushing orientation.

The main purpose of the clinical trial is to develop and analyze a program of Teleorientation of Toothbrushing in children of the Pediatric Dentistry clinic of FORP.

The Specific Objectives are assess whether oral hygiene is taking place properly during the COVID-19 Pandemic, assess, through a questionnaire, the level of understanding of parents and caregivers regarding the information received. This project will be designed as a randomized study with a two-month follow-up. The study factor will be to compare synchronous with asynchronous teleorientation, the effectiveness of knowledge transfer in oral hygiene through video modeling and remote orientation. The response variables will be the assimilation of guidance in oral hygiene by video modeling and by synchronous guidance, the hypothesis is that educational content will have beneficial effects on the oral health of children. The procedures will be performed at the Pediatric Dentistry Clinic of the Faculty of Dentistry of Ribeirão Preto - University of São Paulo - FORP/USP. The CONSORT guide (Schulz et al., 2010) for randomized controlled trials will be followed for the design of the present study.
