About

Title: Effect of the DentalVibe injection system on pain during local anesthesia injections in children.

Purpose: The purpose of this study is to compare self-reported pain scale measurements using the Wong-Baker FACES pain rating scale from an experimental group (local anesthesia injection with DentalVibe system) and a control group (traditional local anesthesia injection with DentalVibe system turned off) in children.

Eligibility: Children age 5-11 years old who require local anesthesia for bilateral dental treatment at University of Nebraska Medical Center (UNMC) pediatric dental clinic. Children must understand and speak English.

Interventions and evaluations: Each patient will have two separate restorative appointments where the DentalVibe will be used during local anesthetic injections. One appointment the DentalVibe will be turned on and one appointment the DentalVibe will be turned off. After each injection the child will be shown the Wong Baker FACES Pain Rating Scale and asked to pick a face associated with their level of hurt during the injection.

Follow-up: All children will be followed up with any necessary recommended dental treatment.

Full description

Up to 50 children between the ages of 5-11 years will participate in this randomized, controlled, cross-over, split-mouth study. There will be no gender restrictions used in this study. Participants will be recruited from a continuous sample of patient seen at the UNMC pediatric dental clinic and will be selected based on their need for dental treatment. Each child will have 2 separate dental appointments.

Written consent will be obtained from parent or guardian prior to first restorative appointment. Verbal consent will be obtained prior to second restorative appointment.

Dr. Marshall will be the provider for every patient. The same dental assistant will be used for each appointment. All treatment will be completed in the same private quiet room. Both Dr. Marshall and the dental assistant will wear the same color scrubs and black lab jackets during all appointments.

One appointment patient will receive local anesthetic dental injection with the DentalVibe turned on and at one appointment the child will receive local anesthetic dental injection with the DentalVibe off. Used strictly as a check/lip retractor. The child will be randomly assigned via a random number generator to either the DentalVibe on or off during the initial appointment. During the DentalVibe turned on appointment, the DentalVibe will be introduced to each child to make him/her familiar with the vibration sensation.

All patients will receive 5 mins of O2, then nitrous oxide (N2O) will be titrated up to 50%N2O/50%O2. When appointment is complete the child will receive 5 mins of 100% O2.

At both restorative appointment a cotton tip applicator with 20% Benzocaine topical anesthetic gel (Patterson) will be administered for 1 min. 2% Lidocaine hydrochloride (HCl) with 1:100,000epinepherine (Patterson Dental) will the be deposited using a medium-length (0.4mm) with 27-gauge short needles. Local anesthetic injections will be referred to as "sleepy juice." Buccal and lingual infiltration will perform on the maxilla. Mandibular blocks will be performed on the mandible. One cartridge of local anesthetic will be used at each appointment. After administration, patient will be shown the Wong Baker FACES pain rating scale and asked to rate the amount of discomfort experienced during the injection by pointing to the face or number. The following manuscript will be used:

"Each face represents a person who has no hurt, or some hurt, or a lot of hurt." "Face 0 doesn't hurt at all. Face 2 hurts just a little bit. Face 4 hurts a little bit more. Face 6 hurts even more. Face 8 hurts a whole lot. Face 10 hurts as much as you can imagine, although you don't have to be crying to have this worst pain." "Touch the face of the hurt you felt when I gave you the sleepy juice."

After child has rated pain Dr. Marshall will continue with restorative treatment. The same process will be followed at the second appointment. Appointments will be scheduled 3-4 weeks apart.
