An interventional study of Inferior Alveolar Nerve Block Anesthesia and Computer-Controlled Intraosseous Anesthesia in Pulpotomies Primary Teeth, sponsored by Afyonkarahisar Health Sciences University. Recruiting at 1 site in Turkey (Türkiye). Open to participants aged 6 Years to 9 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-09-14.

The goal of this clinical trial is to compare the effects of two local anesthesia techniques on pulp hemostasis time during pulpotomy treatment of mandibular primary molars in children aged 6-9 years.
The main questions it aims to answer are:
Does the local anesthesia technique affect the time required to achieve pulp hemostasis during pulpotomy? Are there differences between the two anesthesia techniques in terms of pain, heart rate, and oxygen saturation during treatment?
Researchers will compare conventional inferior alveolar nerve block anesthesia with computer-controlled intraosseous local anesthesia using the QuickSleeper 5 system to determine whether the anesthesia technique affects pulp hemostasis time and the secondary clinical outcomes.
Each participant will receive both anesthesia techniques in a randomized order using a split-mouth design. Participants will:
Receive conventional inferior alveolar nerve block anesthesia for pulpotomy treatment of one mandibular primary molar.
Receive computer-controlled intraosseous local anesthesia using the QuickSleeper 5 system for pulpotomy treatment of the contralateral mandibular primary molar at a separate treatment session.
Have pulp hemostasis time recorded during each pulpotomy procedure. Have pain, heart rate, and oxygen saturation assessed during the treatment procedures.

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants allocated to this sequence will receive conventional inferior alveolar nerve block (IANB) anesthesia for pulpotomy treatment of one mandibular primary molar at the first treatment session. At the second treatment session, computer-controlled intraosseous anesthesia will be administered for pulpotomy treatment of the contralateral mandibular primary molar. The time required to achieve pulp hemostasis will be recorded during both treatment sessions.
Procedure: Inferior Alveolar Nerve Block Anesthesia · Procedure: Computer-Controlled Intraosseous Anesthesia
Computer-controlled intraosseous local anesthesia will be administered using the QuickSleeper 5 system (Dental Hi-Tec, France) before pulpotomy treatment of the mandibular primary molar. After adequate anesthesia is achieved, pulpotomy will be performed according to the study protocol, and the time required to achieve pulp hemostasis will be recorded.
Procedure: Inferior Alveolar Nerve Block Anesthesia · Procedure: Computer-Controlled Intraosseous Anesthesia
Conventional inferior alveolar nerve block anesthesia will be administered before pulpotomy treatment of the mandibular primary molar using a standard dental syringe and an articaine-based local anesthetic solution (Ultracain D-S Forte). After adequate anesthesia is achieved, pulpotomy will be performed according to the study protocol. Pulp hemostasis time will be recorded following removal of the coronal pulp tissue.

After adequate anesthesia is achieved, pulpotomy will be performed according to the study protocol. Pulp hemostasis time will be recorded following removal of the coronal pulp tissue
Pulp Hemostasis Time
The time required to achieve pulp hemostasis following removal of the coronal pulp tissue during pulpotomy will be recorded for each treatment session. Hemostasis will be assessed using standardized sterile cotton pellets and categorized according to the time required to achieve bleeding control: ≤2 minutes, \>2 to 5 minutes, or failure to achieve hemostasis within 5 minutes.
Time frame: During pulpotomy, up to 5 minutes after coronal pulp removal
Pain Intensity
Pain intensity will be assessed using the Wong-Baker FACES Pain Rating Scale. Participants will select the face that best represents their perceived pain. The scale ranges from 0 (no pain) to 10 (worst pain), with higher scores indicating greater pain intensity. Pain will be assessed after administration of local anesthesia and after completion of the pulpotomy procedure.
Time frame: Immediately after local anesthesia administration and immediately after completion of the pulpotomy procedure, during each treatment visit
Heart Rate
Heart rate will be measured using a pulse oximeter and recorded as beats per minute (bpm) to evaluate physiological changes associated with the anesthesia and pulpotomy procedures.
Time frame: Immediately before local anesthesia administration and immediately after local anesthesia administration, during each treatment visit
Peripheral Oxygen Saturation (SpO₂)
Peripheral oxygen saturation (SpO₂) will be measured using a pulse oximeter and recorded as a percentage (%) to evaluate physiological changes associated with the anesthesia and pulpotomy procedures.
Time frame: Immediately before local anesthesia administration
