This will be a randomized, controlled, parallel-group clinical trial. The aim of this studio will be to evaluate the effectiveness of "Hands/Eyes/mouth" behavior management technique versus a conventional technique (covering the patient´s vision) during an inferior alveolar and lingual nerve block in preschool children referred for treatment at the School of Dentistry, Cardenal Herrera CEU University (Valencia, Spain). The sample will consist of 52 children from 3 years old to 5 years 11 months old who need dental pulp treatment and/or tooth extraction of primary molars. Preschool children with no history of allergies to Lidocaine or systemic/neurological diseases and who did not take local anesthesia before the study will be include in this research.
Children will be randomly allocated to treatment groups (n=26 for each group) according to the technique: 1)"Hands/Eyes/mouth" and 2) Conventional. Anxiety and pain will be evaluated by the Scale of facial Image (EIF) and Wong-Baker Pain Scale, respectively. The cooperation of the patient will be evaluated by behavioral Scale Frank

The needle is inserted laterally to the pterygomandibular pit at its deepest point without noticing any resistance. In children the positioning of the syringe must be perpendicular, between the canine and the first molar on the opposite side and puncture is performed slightly below the occlusal plane. It was initially deposited 2/3 anesthetic carpule solution and then the needle is slightly recede depositing there the remaining third of anesthetic solution. The application of anesthesia shall be in accordance with the following guidelines: 1. Topical Anesthetic: Benzocaine 20% (Hurricaine, Clarben Laboratories SA, Madrid, Spain). 2. Dental Needle: short needles (21mm/30g) (Octoplus, Clarben Laboratories SA, Madrid, Spain) 3. anesthetic: lidocaine hydrochloride 2% with epinephrine 1: 100,000 (2% XILOCAINE, Dentsply, Spain). 4. Syringe: carpule syringe-conventional harpoon with suction system.

The children will be asked to point at which face they felt most like at that moment (row of five faces ranging from very happy to very unhappy-FIS)

Preschool children´s pain levels-Wong Baker Faces Pain Scale
The children will be asked to point at which face they felt most like at that moment (row of six faces ranging from very happy-does not hurt to very unhappy-hurt as much as you can imagine)
Time frame: At the end of local anesthesia procedure (2 minutes)
