Anxiety and pain are emotions that the child often experiences in the dental office, generating the appearance of negative, uncooperative and even disruptive behaviors during the treatment; these make it difficult for dental care and the possibility of establishing a relationship of trust between the pediatric dentist and the patient. The pediatric dentist must promote a positive attitude of the child throughout the dental treatment, keep the child calm and avoid feeling pain is essential at each appointment.

When carrying out dental treatments that are more invasive or painful for the patient, such as pulpotomies, it is difficult to distinguish and separate anxiety from pain.

In this project, anxiety/pain will be managed as a whole, to assess it with the same scale, and to correlate the scores obtained with the variations in skin conductance and heart rate, before, during and after perform pulpotomies in children.

Inclusion Criteria:

• Without previous dental experiences, patients with clinical and radiographic indication of pulpotomy in at least one temporary inferior molar, clinically healthy patients, patients whose parents accept entry into the study and who sign the informed consent.

Exclusion Criteria:

• Patients who have received hypnosis before.
