NCT07736677

Brief Summary

This multicentre, randomized clinical trial compared digital intraosseous anaesthesia with conventional local anaesthetic techniques in children aged 6-12 years receiving restorative treatment for MIH-affected permanent first molars. Within the maxillary stratum, digital intraosseous anaesthesia was compared with conventional infiltration anaesthesia; within the mandibular stratum, it was compared with inferior alveolar nerve block. The primary outcome was child-reported pain during restorative treatment. Secondary outcomes included pain during needle penetration and anaesthetic solution delivery, observed pain-related behaviour, and change in dental anxiety.

Outcome Measures

Primary Outcomes (1)

  • Child-Reported Pain During Dental Treatment Assessed Using the Wong-Baker FACES Pain Rating Scale

    Children rated the pain experienced during the restorative procedure using the Wong-Baker FACES Pain Rating Scale. The scale comprises six faces scored 0, 2, 4, 6, 8, and 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.

    During the restorative procedure after local anesthesia administration, within the single treatment visit

Secondary Outcomes (4)

  • Child-Reported Pain During Needle Penetration Assessed Using the Wong-Baker FACES Pain Rating Scale

    At the time of needle insertion into the oral mucosa, immediately before delivery of the local anaesthetic solution, during the single treatment visit

  • Child-Reported Pain During Local Anaesthetic Solution Delivery Assessed Using the Wong-Baker FACES Pain Rating Scale

    During delivery of the local anaesthetic solution, immediately after needle penetration, during the single treatment visit

  • Observer-Rated Pain-Related Behaviour During Local Anaesthetic Administration Assessed Using the FLACC Scale

    During the local anaesthetic injection sequence, from needle penetration through completion of anaesthetic solution delivery, before commencement of the restorative procedure, during the single treatment visit

  • Change in Dental Anxiety From Before to After Local Anaesthetic Administration Assessed Using the Modified Child Dental Anxiety Scale

    Immediately before and immediately after local anaesthetic administration, during the single treatment visit

Study Arms (4)

Maxillary Digital Intraosseous Anaesthesia Group

EXPERIMENTAL

Children in this arm received computer-controlled digital intraosseous anaesthesia using the SleeperOne 5 system before restorative treatment of one MIH-affected permanent first molar in the maxillary arch.

Device: SleeperOne 5 Computer-Controlled Intraosseous Anaesthesia System

Conventional Maxillary Infiltration Anaesthesia Group

ACTIVE COMPARATOR

Children in this arm received conventional supraperiosteal infiltration anaesthesia in the buccal sulcus adjacent to one MIH-affected maxillary permanent first molar before restorative treatment.

Procedure: Conventional Maxillary Infiltration Anaesthesia

Conventional Mandibular Inferior Alveolar Nerve Block Group

ACTIVE COMPARATOR

Children in this arm received conventional inferior alveolar nerve block anaesthesia before restorative treatment of one MIH-affected mandibular permanent first molar.

Procedure: Conventional Inferior Alveolar Nerve Block Anaesthesia

Mandibular Digital Intraosseous Anesthesia Group

EXPERIMENTAL

Children in this arm received computer-controlled digital intraosseous anaesthesia using the SleeperOne 5 system before restorative treatment of one MIH-affected permanent first molar in the mandibular arch.

Device: SleeperOne 5 Computer-Controlled Intraosseous Anaesthesia System

Interventions

Digital intraosseous anaesthesia was administered using the SleeperOne 5 computer-controlled system (Dental Hi Tec, Cholet, France). Initial mucosal anaesthesia was achieved using 0.1-0.2 mL of 4% articaine with 1:200,000 epinephrine, followed by intraosseous administration of an additional 1 mL of the same anaesthetic solution at the device-controlled slow flow rate.

Mandibular Digital Intraosseous Anesthesia GroupMaxillary Digital Intraosseous Anaesthesia Group

Supraperiosteal infiltration anaesthesia was performed using a standard aspirating dental syringe and a 27-gauge short needle. One millilitre of 4% articaine with 1:200,000 epinephrine was deposited slowly into the buccal sulcus adjacent to the MIH-affected maxillary permanent first molar.

Conventional Maxillary Infiltration Anaesthesia Group

Inferior alveolar nerve block anaesthesia was administered using a standard aspirating dental syringe and a 27-gauge long needle. One millilitre of 4% articaine with 1:200,000 epinephrine was deposited slowly. Adequate anaesthesia was confirmed by patient-reported lip numbness before restorative treatment was started.
