Different Local Anesthesia Techniques for Mandibular Primary Molar Pulpectomy

11. august 2026 oppdatert av: DİLARA NİL GÜNAÇAR, Recep Tayyip Erdogan University Training and Research Hospital

Comparison of Computer-Controlled and Conventional Local Anesthesia Techniques on Dental Anxiety and Pain During Mandibular Primary Molar Pulpectomy: A Split-Mouth Randomized Clinical Trial

This study aims to compare the effects of computer-controlled local anesthesia and conventional inferior alveolar nerve block on dental anxiety and pain in children undergoing pulpectomy of mandibular primary molars. Both anesthesia techniques are routinely used in pediatric dental practice and are considered standard methods of care.

Children aged 6 to 8 years who require bilateral pulpectomy of mandibular primary molars will be included in this split-mouth randomized clinical trial. Each participant will receive both anesthesia techniques during separate treatment sessions. Dental anxiety, pain, and physiological parameters, including heart rate, blood pressure, oxygen saturation, and body temperature, will be assessed before, during, and after treatment using validated pediatric assessment scales and routine clinical measurements.

The findings of this study may help identify the anesthesia technique that provides greater comfort and reduces anxiety and pain during pediatric dental treatment, thereby improving the overall treatment experience for children.

Våpen og intervensjoner

Deltakergruppe / Arm
Intervensjon / Behandling
Aktiv komparator: Conventional Inferior Alveolar Nerve Block
Fremgangsmåte: Conventional Inferior Alveolar Nerve Block
Conventional inferior alveolar nerve block administered with a standard dental syringe for mandibular primary molar pulpectomy.
Legemiddel: Articaine hydrochloride with epinephrine 1:100,000
A 4% articaine hydrochloride solution with epinephrine 1:100,000 was used as the local anesthetic solution in both study groups.
Enhet: Standard Dental Aspirating Syringe
A conventional dental aspirating syringe was used for manual administration of the local anesthetic solution.
Aktiv komparator: Computer-Controlled Local Anesthesia
Legemiddel: Articaine hydrochloride with epinephrine 1:100,000
A 4% articaine hydrochloride solution with epinephrine 1:100,000 was used as the local anesthetic solution in both study groups.
Fremgangsmåte: Computer-Controlled Local Anesthesia
Computer-controlled delivery of local anesthetic for mandibular primary molar pulpectomy.
Enhet: Computer-Controlled Local Anesthetic Delivery System
A computer-controlled local anesthetic delivery device was used to deliver the anesthetic solution at a constant, pre-programmed injection rate.

Hva måler studien?

Primære resultatmål

Resultatmål
Tiltaksbeskrivelse
Tidsramme
Dental Anxiety
Tidsramme: Baseline and immediately after treatment
Dental anxiety assessed using the Modified Child Dental Anxiety Scale-faces version (MCDASf). Higher scores indicate higher levels of dental anxiety.
Baseline and immediately after treatment
Behavioral Pain During Local Anesthesia
Tidsramme: Immediately after local anesthetic injection
Behavioral pain assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) scale during local anesthesia administration. Scores range from 0 to 10, with higher scores indicating greater pain.
Immediately after local anesthetic injection

Tidsramme
Self-reported Pain
Tidsramme: Immediately after local anesthetic injection
Pain assessed using the Wong-Baker FACES Pain Rating Scale immediately after treatment. Self-reported pain assessed using the Wong-Baker FACES Pain Rating Scale (0-10) immediately after completion of pulpectomy. Scores range from 0 to 10, with higher scores indicating greater pain intensity.
Immediately after local anesthetic injection
Facial Image Scale (FIS) Score
Tidsramme: Baseline and immediately after treatment.
Emotional status assessed using the Facial Image Scale (FIS). Higher scores indicate greater anxiety. Emotional status assessed using the Facial Image Scale (FIS). The scale ranges from 1 to 5, with 1 indicating no anxiety (very happy face) and 5 indicating severe anxiety (very unhappy face). Higher scores indicate greater anxiety.
Baseline and immediately after treatment.
