Bite force will be measured using a digital gnathodynamometer (DMD, Kratos Equipamentos Industriais Ltda, Cotia, São Paulo, Brazil) adapted for oral conditions. Readings will be taken in the region of the first molars. The participants will receive instructions and previous training to become familiarized with the device. According to the specific literature, the vertical movement of the mandible in the age group analyzed ranges from 35 to 40 mm. The digital dynamometer adapted to oral conditions has a capacity of up to 100 Kgf and has two beams measuring approximately 10 mm in diameter to avoid muscle stretching and ensure that the vertical movement of the mandible does not affect the force employed.
