Background: Primary lower incisors are susceptible to traumatic dental injury (TDI), which may affect both primary and permanent dentitions.
Aim: This study aimed to evaluate the prevalence of TDIs in the primary lower incisors and the factors associated with their occurrence and with the incidence of sequelae in the permanent successor teeth.
Design: Dental files (n = 2926) from patients who attended a reference center for dental trauma in the primary teeth, from 1998 to 2020, were screened.

Objective: The present study investigated how a hybrid light source (LED/laser) influences temperature variation on the enamel surfaces during 35% hydrogen peroxide (HP) bleaching. Effects on the whitening effectiveness and tooth sensitivity were analyzed.
Method And Materials: Twenty-two volunteers were randomly assigned to two different treatments in a split-mouth experimental model: group 1 (control), 35% HP; group 2 (experimental), 35% HP + LED/laser.
