Descrição detalhada
This randomized controlled clinical trial aims to compare pain perception of Vibraject and dental vibe during inferior alveolar nerve block in lower primary molars indiacted for extraction,pulp therapy and cavity preparation in children aged 6-8 years.
Pain during local anesthesia remains a major concern in pediatric dentistry, as it contributes significantly to fear, anxiety, and uncooperative behavior in children. Vibration devices, based on the gate control theory of pain, have been introduced as a non-pharmacological method to reduce injection discomfort.
Ninety children will be randomly allocated into 3 parallel groups(1:1:1): Inferior alveolar nerve block Injection using Vibraject system,Inferior alveolar nerve block Injection using Dentalvibe system, Inferior alveolar nerve block Injection using the Conventional Syringe.
All participants will undergo standardized procedures, including topical anesthesia application followed by local anesthetic injection using articaine. Pain perception during injection will be assessed using both subjective and objective measures.
The primary outcome is subjective pain perception during injection measured using Wong-Baker Scale,While secondary outcome is objective pain perception during injection measured using FLACC Scale,Finally The Physiological parameters(heart rate, oxygen saturation )will be measured at two time points: baseline and during injection using pulse oximeter device on child's index finger.
The Findings of this study aims to provide evidence-based guidance on the optimal non pharmacological technique to enhance pain-controlled dental procedures allowing better quality of dental treatment and Improve the patient's cooperation and acceptance for future dental visits.

Experimental: Inferior alveolar nerve block Injection using Vibraject system(MiltexInc LLC.,York,PA,USA).
VibraJect is a compact, battery-operated unit that attaches directly to a standard dental syringe, generating high-frequency vibrations along the needle to attenuate pain during anesthetic delivery.
If these devices prove efficacy, they may offer a rapid, non-pharmacologic method to enhance the comfort of children undergoing local anesthesia.
|
Familiarize the child with the Vibraject device, allowing them to feel the vibrations on their hand to reduce anxiety. Dry the injection site with sterile gauze. Apply 20% benzocaine gel for 1 minute using a cotton swab. Use a conventional syringe with the Vibraject attachment, 4% articaine (1:100,000 epi), and a 27-gauge long needle. Deliver an inferior alveolar and lingual nerve block. Slowly deposit 1.5 mL of anesthetic over at least 60 seconds to minimize discomfort. Use the FLACC scale (objective) during injection and the Wong-Baker FACES scale (subjective) immediately after. Monitor heart rate and oxygen saturation via pulse oximetry at baseline and during injection. Confirm anesthesia after 3-5 minutes via numbness (subjective) and lack of pain during instrumentation (objective). Perform (extraction or pulp therapy or cavity preparation) per AAPD guidelines. Provide post-operative instructions to the parent and evaluate the need for a space maintainer. |

Experimental: Inferior alveolar nerve block Injection using Dentalvibe system (BING Innovations LLC,Crystal La).
The DentalVibe device is a cordless, rechargeable instrument that produces controlled, pulsed micro-vibrations at the injection site.
It features a U-shaped vibrating tip connected to a microprocessor-driven VibraPulse motor, allowing gentle stimulation of sensory receptors, illumination of the injection area, and retraction of the cheek or lip.
|
Familiarize the child with the DentalVibe device, letting them feel the vibrations on the back of their hand. Dry the mucosa with gauze and apply 20% benzocaine gel for 1 minute. Apply the DentalVibe to the buccal mucosa for pre-injection vibration. Using a conventional syringe (4% articaine, 1:100,000 epi, 27G needle), perform the mandibular block simultaneously while the DentalVibe is active. Slowly deposit 1.5 mL (1.0 mL alveolar / 0.5 mL lingual) over at least 60 seconds. Evaluate pain using the FLACC scale (during) and the Wong-Baker FACES scale (after). Record heart rate and oxygen saturation at baseline and during the injection. After 3-5 minutes, confirm anesthesia via subjective numbness and objective lack of pain during instrumentation. Perform treatment (extraction/pulp therapy/cavity prep) per AAPD guidelines. Provide post-operative care instructions and assess the need for space maintainers. |

Comparador Ativo: Inferior alveolar nerve block Injection using the Conventional Syringe.
A conventional metal aspirating syringe
|
Dry the injection site with sterile gauze. Apply 20% benzocaine gel for 1 minute using a cotton swab to ensure surface numbing. Use a conventional metal aspirating syringe with 4% articaine (1:100,000 epi) and a 27-gauge long needle. Deliver a mandibular inferior alveolar nerve block. Slowly deposit 1.5 mL total (1.0 mL for the alveolar nerve and 0.5 mL for the lingual nerve) over a minimum of 60 seconds. Evaluate pain using the FLACC scale (during) and the Wong-Baker FACES scale (after). Record heart rate and oxygen saturation at baseline and during the injection. After 3-5 minutes, confirm anesthesia via subjective numbness and objective lack of pain during instrumentation. Perform (extraction, pulp therapy, or cavity preparation) according to AAPD guidelines. Provide post-operative care instructions and evaluate the patient for potential space maintainer requirements. |

Wong-Baker Scale: represents a series of faces from a 0-value happy face (which represents lack of pain) to a 10-value crying face (which suggests the worst possible pain).
On this basis, the patient chooses the face that best describes his/her level of pain.

Faces, Legs, Arms, Crying, Consolability (FLACC) scale: a measurement tool used to assess the intensity of pain for young children and infants or children that are unable to communicate their pain with exposed body and limbs. The scale is scored in a range of 0-10 with 0 representing no pain. The observation lasts for 2-5 minutes. Each parameter is evaluated on a scale from 0 to 2; the total score is interpreted as follows: 0=relaxed and comfortable, 1-3=mild discomfort, 4- 6=moderate pain, 7-10=severe discomfort/pain. - Physiological parameters (heart rate, oxygen saturation ) at two time points: baseline, during injection using pulse oximeter Pulse oximetry: non-invasive monitoring technique that measures the heart rate and the oxygen saturation in the blood by shining light at specific wavelengths through tissue, most commonly the fingernail bed, pulse oximetry is the standard of care to use pulse oximetry to monitor oxygen saturation for patients receiving anesthesia. |
