Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Experimental: A) Experimental Group (CC-ILA using Super Pen)

A) Experimental Group (CC-ILA using Super Pen)

  • CC-ILA will be administered with the Super Pen according to manufacturer instructions.
  • A standard 1.8 mL Articaine carpule will be used. The injection will be initiated at the distolingual line angle of the target tooth, with the needle inserted through the gingival sulcus at approximately a 30° angle to the long axis, bevel facing the alveolar bone.
  • Approximately 0.2 mL of 4% Articaine with 1:100,000 epinephrine will be delivered per root.24
  • The visual pressure indicator will be monitored to ensure controlled delivery within optimal pressure ranges. Slight tissue blanching will indicate adequate deposition. The procedure will be repeated at the mesiolingual line angle.
Device: Experimental Group (CC-ILA using Super Pen)
  • A standard 1.8 mL Articaine carpule will be used. The injection will be initiated at the distolingual line angle of the target tooth, with the needle inserted through the gingival sulcus at approximately a 30° angle to the long axis, bevel facing the alveolar bone.
  • Approximately 0.2 mL of 4% Articaine with 1:100,000 epinephrine will be delivered per root.
  • The visual pressure indicator will be monitored to ensure controlled delivery within optimal pressure ranges. Slight tissue blanching will indicate adequate deposition. The procedure will be repeated at the mesiolingual line angle.
Active Comparator: B) Control Group (Conventional IANB Technique)
  • A 27-gauge 3 cm long needle will be used to administer Articaine 4% with 1:100,000 epinephrine via the standard IANB approach, followed by long buccal infiltration.
  • After negative aspiration, approximately 1.0 mL of solution will be delivered near the inferior alveolar nerve, and 0.5 mL as a buccal infiltration distal to the second primary molar.25
  • Anesthesia onset will be confirmed by gingival probing at 10-second intervals (CC-ILA) or 30-second intervals (IANB).
Device: Experimental Group (CC-ILA using Super Pen)
  • A standard 1.8 mL Articaine carpule will be used. The injection will be initiated at the distolingual line angle of the target tooth, with the needle inserted through the gingival sulcus at approximately a 30° angle to the long axis, bevel facing the alveolar bone.
  • Approximately 0.2 mL of 4% Articaine with 1:100,000 epinephrine will be delivered per root.
  • The visual pressure indicator will be monitored to ensure controlled delivery within optimal pressure ranges. Slight tissue blanching will indicate adequate deposition. The procedure will be repeated at the mesiolingual line angle.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Heart rate
Time Frame: immediately after the procedure (within the same treatment visit)
Heart rate will be monitored using a pulse oximeter at baseline, during LA injection, and during extraction. Readings will be recorded every two minutes and mean values will be calculated.
immediately after the procedure (within the same treatment visit)
Oxygen saturation
Time Frame: immediately after the procedure (within the same treatment visit)
Oxygen saturation will be monitored using a pulse oximeter at baseline, during LA injection, and during extraction. Readings will be recorded every two minutes and mean values will be calculated.
immediately after the procedure (within the same treatment visit)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Objective Pain assessment
Time Frame: immediately after the procedure (within the same treatment visit).
Pain will be assessed using the Sound, Eye, and Motor (SEM) Scale. Each component will be graded from 1 (comfort) to 4 (severe discomfort) by the operator and the independent outcome assessor evaluator reviewing video recordings.
immediately after the procedure (within the same treatment visit).
Subjective Pain assessment
Time Frame: immediately after the procedure (within the same treatment visit).
Pain perception will be recorded after anesthesia and Extraction using a modified facial expression scale. Children will choose from three schematic faces representing satisfaction, indifference, or dissatisfaction.
immediately after the procedure (within the same treatment visit).

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Measure Description
Time Frame
Adverse Event Assessment
Time Frame: 24 hours
Parents will be questioned during the 24-hour follow-up regarding any unusual symptoms.

Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
