The dental environment can be considered a stressor for children, and can trigger unwanted behaviors. Pediatric Dentistry is a specialty that requires professionals to know preventive measures and restorative skills to perform dental treatment in children or adolescents. In addition, it is especially important that the professional is concerned with the child’s feelings and reactions, allowing the pediatric dentist to identify situations that may generate stress for the patient during the care, and manage the presented behaviors. Recent studies have measured children’s reactions and feelings during dental treatments using projective techniques. Given the importance of drawing to identify children’s emotions, the objective of this study was to search the literature about the use of drawings as a projective technique in Pediatric Dentistry. Therefore, projective techniques, with an emphasis on drawing, have proved to be an effective instrument to be used in clinical practice to better understand the reactions presented by children during dental care and their relationship with dentists. Thus, avoiding unexpected situations in the office and allowing greater chances of obtaining a positive return from the patient.
