The goal of this clinical trial is to learn if Computer Controlled Local Anesthetic Delivery (CCLAD) results in lower pain during local anesthesia administration for infiltration in the buccal region of the upper jaw in patients between 6 and 16 years old who will receive a dental treatment. The main questions it aims to answer are: * Does CCLAD result in lower self-reported pain (Visual Analogue Scale (VAS) and Face Pain Scale-Revised (FPS-R)) for patients between 6 and 16 years old who need local anesthesia in the upper jaw for a dental treatment? * Does CCLADD result in lower observed pain (Sound Eye Motor Scale (SEM)) for patients between 6 and 16 years old who need local anesthesia in the upper jaw for a dental treatment? * Does CCLAD result in lower hearth rate (HR) and galvanic skin response (GSR) for patients between 6 and 16 years old who need local anesthesia in the upper jaw for a dental treatment? Researchers will compare CCLAD (Dentapen, Septodont, France) to conventional local anesthesia infiltration with a metallic syringe to see if the infiltration is less painful in patients between 6 and 16 years old who will receive a dental treatment. Participants will receive local anesthesia either with the Dentapen or metallic syringe. * GSR and heart rate are measured before anesthesia, during needle insertion, at 0.3 - 0.6 - 0.9ml, and after anesthesia. * Post-injection, the child provides VAS scores (if 8 years or older) and FPS-R (all patients). * A researcher not administering the injection determines the SEM score.

Visual Analog Scale (VAS)
The Visual Analog Scale is a self-report pain assessment tool applicable from the age of eight. The scale is a 100mm line, where 'no pain' is on the left and 'severe pain' is on the right. Patients indicate the level of pain experienced during local anesthesia by marking this scale. The scale is generally interpretted as follows: 0-4 mm (0-0.4): No pain or mild pain; 5-44 mm (0.5-4.4): Mild pain; 45-74 mm (4.5-7.4): Moderate pain; 75-100 mm (7.5-10): Severe pain. A higher score thus means a worse outcome.
Time frame: Immediately after intervention, the child provides VAS scores.
Face Pain Scale-Revised (FPS-R)
The Face Pain Scale-Revised (FPS-R) is a self-report pain measurement tool. The scale consists of six gender neutral faces devoid of smiles or tears. Each face corresponds to a score ranging from zero to ten, with only the even numbers used. It is important to employ appropriate language while utilizing the FPS-R. You can use short phrases like 'this face means no pain' or 'this face means very much pain', avoiding the terms 'happy' and 'sad'. In this study the Face Pain Scale-Revised will be used from the age of six. The specific scores for each face from left to right are: 0, 2, 4, 6, 8, 10. A higher score means a worse outcome.
Time frame: Immediately after intervention, the child provides FPS-R scores.
Galvanic Skin Response (GSR)
The Galvanic Skin Response, also known as the psychogalvanic Reflex, is used to measure the stress reaction. During local anesthesia, individuals commonly undergo a stress response, triggering an elevation in sympathetic activity. The rise in sympathetic tone activates the sweat glands. As a result, the resistance of the skin decreases, and the electrical conduction increases. To measure these changes, two electrodes are placed, one on the index finger and the other on the middle finger, and these are linked to the application "Mindfield eSense". A higher Galvanic Skin Response is correlated to higher stress and thus a worse outcome.
Time frame: GSR is measured pre-intervention; periprocedurally during needle insertion at 0.3 - 0.6 - 0.9ml, and immediately after intervention.
Heart rate (HR)
Stress and anxiety trigger the autonomic nervous system. This acts on the parasympathetic system, which is suppressed, and the sympathetic system, which is activated. Due to activation of the sympathetic system epinephrine and norepinephrine are released from the adrenal glands. The release of these hormones causes vasoconstriction in the blood vessels, increased blood pressure and increased heart rate. In this study, the heart rate will be measured with a pulse oximeter. A higher heart rate is a worse outcome.
Time frame: Heart rate is measured pre-intervention; periprocedurally during needle insertion at 0.3 - 0.6 - 0.9ml, and immediately after intervention.
Sound Eye Motor Scale (SEM)
The Sound Eye Motor (SEM) scale is used to assess children's responses during local anesthesia. Three parameters are considered: sound, eyes and motor skills. Each parameter is divided into 4 categories: comfort, mild comfort, moderate discomfort and severe discomfort, with corresponding scores from 1 to 4. The total score is derived by adding up the scores from these parameters, with a maximum possible score of 12 and a minimum of 3. A higher score is a worse outcome.
Time frame: A researcher not administering the injection determines the SEM score periprocedurally, from the start of injection until 1,2 minutes later when the injection has been completed.
