NCT05793905

Brief Summary

In a prospective, randomized clinical trial, triple-blind, split-mouth study, 40 children aged between 7 to 10 with bilateral mandibular primary molars were diagnosed with pulpitis. The test agent was 2% lidocaine with 1:80.000 epinephrine buffered with sodium bicarbonate 8.4% at a ratio of 1/10, as opposed to the control agent, which was non- buffered 2% lidocaine with 1:80,000 epinephrine. The pain will be assessed during inferior alveolar nerve block injection (IANB) and the effectiveness of anesthesia using the subjective Wong-Baker visual analog scale, the objective sound, eye, and motor (SEM) scale, and the physiological pain scale (pulse rate) using a pulse oximeter. The investigator has confirmed the onset of anesthesia after lip tongue-numbing by probing the gingiva until there is no pain. Endo-ice has been used to assess the onset of pulp anesthesia.

Outcome Measures

Primary Outcomes (6)

  • Probing the gingiva

    The onset of anaesthesia at soft tissue will be assessed by probing the gingiva After IANB injection.

    directly after asking the child about lip, tongue numbing every 30 seconds until there is no pain.

  • Endo - ice test

    The investigator will use endo-ice to assess the onset time of pulp anaesthesia.

    Every 30 seconds after confirmed soft tissues anaesthesia until the absence of pain.

  • Pulse rate

    Pulse rate is a physiological pain scale which will be taken through a finger pulse oximeter.

    A minute before anaesthesia.

  • Pulse rate

    Pulse rate is a physiological pain scale, will be taken through a finger pulse oximeter.

    20 seconds after the first quarter of the local anaesthesia.

  • Wong baker faces scale.

    Wong Baker faces scale is a subjective pain which contains a series of six faces ranging from a happy face at 0 to indicate "no hurt" to a crying face at 10 to indicate "hurts worst"

    One minute after IANB injection

  • Sound, eye, motor scale (SEM)

    Sound, eye, motor scale is an objective pain scale for the assessment of child's behaviour by recording video during anaesthesia

    Within five seconds from the start of the local anesthetic injection to completion

Secondary Outcomes (3)

  • Pulse rate

    20 seconds after opening the pulp chamber

  • Wong baker faces scale

    one minute after preparing pulp chamber

  • sound, eye, motor scale (SEM)

    Within five seconds from the start of the local anaesthetic injection to completion

Eligibility Criteria

Age6 Years - 10 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17)

You may qualify if:

  • Children who are healthy and free of any underlying conditions that might make local anesthesia impossible to administer.
  • Children that are not allergic to (lidocaine, adrenaline, or sodium bicarbonate).
  • Children aged 6-10 years old
  • Cooperative children on Frankel scale (positive or absolute positive).
  • children needing bilateral (right and left) endodontic treatment for the mandibular primary molars.
  • A positive outcome on the cold test for the target tooth.

You may not qualify if:

  • Uncooperative children on Frankel's scale (passive or absolute positive).
  • The presence of a fistula.
  • The presence of an abscess associated with the target tooth.
  • The presence of a periapical lesion radially.
  • Negative response to the cold test.
  • Children suffering from systemic conditions.
  • Children who are allergic to (lidocaine, adrenaline, sodium bicarbonate).
