About

Dental Fear and Anxiety (DFA) are at higher levels among children and often leads to avoidance of dental treatment. Negative experiences in the early years such as experience of pain during injections, fillings, or extractions may lead to difficulties in treatment and behavior management among children. During dental procedures such as restorations and extractions injectable anesthetics are required as they are used to anesthetize and numb the area around the tooth receiving treatment. Topical anesthetics are used prior to using injectable anesthetic to alleviate some pain and discomfort. Topical anesthetics should be used with caution as they consist of more concentrated doses of pharmaceutical elements used in injectable anesthetics. Such high concentrations can result in increased gag reflux, central nervous system depression and cardiovascular effects in rare cases. With many recent advances in dental treatment, there is also a need for new non-pharmaceutical strategies to alleviate pain and discomfort among children which in turn will motivate children and their parents to visit the dental clinic more frequently. Electronic anesthesia or Synapse Transcutaneous Electronic Nerve Stimulation (TENS), a non-invasive device that uses low energy electrical stimulation to reduce pain perception, has gained acceptance since the 1990s. Advantages of using the TENS device are that it is safe, easy to use, well-accepted among patients as evidenced in the few trials conducted so far, no adverse complications and has been successful in alleviating pain during dental procedures. This study aims to explore use of the TENS to alleviate pain and discomfort at the oral mucosal site where the patient will receive a local anesthetic injection. In this randomized case-crossover trial among children aged 6-14 years the effectiveness of Aleve TENS device in reducing pain and anxiety among children prior to receiving injectable local anesthetic agent during dental procedures is compared to those who receive the local anesthetic gel prior to receiving local anesthetic injection.

Full description

Children between 6-14 years will be recruited at the Pediatric Oral Healthcare Center. A sample of 100 male and female children who fit the inclusion and exclusion criteria are recruited. Once parents' consent at the first visit basic demographic information, dental and medical history information is collected. This study is conducted in total of two clinic visits. In the first visit participants are randomized to either the intervention group or the comparison group. The intervention group receives the experimental device (TENS) prior to local anesthetic injection whereas the comparison group receives the local anesthetic gel. Following this the participants receive the local anesthetic injection after which treatment is completed. In the second visit the participants are crossed over to the other group and therefore randomization is not used for visit 2. Those who received the local anesthetic gel in visit 1 will receive the experimental device in visit 2 and those who received the experimental device in visit 1 will receive the local anesthetic gel in visit 2 . Following this treatment procedures are completed.

Sex: All

Ages: 6 to 14 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Children who are healthy and without any major medical conditions
• Children who are patients at the Pediatric Oral Healthcare Center
• Children requiring restoration on the occlusal surface that involves tooth preparation up to the dentin level in at least two primary or permanent molars or children requiring extractions of primary or permanent molars.
• Children who are scheduled for at least two appointments and who require two restorative procedures or two extractions than can be scheduled over two separate appointments

Exclusion criteria

• Children who have contraindications to local anesthetic
• Children with teeth requiring restoration and have pulp involvement and root resorption on radiological examination (i.e. deep caries)
• Children who have major medical problems

Synapse TENS device

Experimental group

Description:

SYnapse TENS device will be used for alleviating pain through electrical stimulation. This is a battery powered device where an electrical current is applied intra-orally on the buccal and lingual sides using an intra-oral pad applicator. This device has been cleared for marketing by the Food and Drug Administration (FDA) and the prescribed electrical field falls almost a 10 factor level lower than routine pulp testing devices used in dentistry. The TENS device was previously tested in a pilot study with promising results. Chair side application and at-home use of the device by the patient was shown to drastically reduce pain and discomfort associated with orthodontic tooth movement.

Treatment:

Device: Synapse TENS device

Topical anesthetic gel

Active Comparator group

Description:

Topical anesthetic Gel is the active comparator in this study. The topical anesthesia (anesthetic gel) Centrix LolliCaine with 20% benzocaine in single package of 0.3 ml will be used. The amount of local anesthetic used will not exceed the maximum allowable dose, which will be calculated for each patient based on his/her age and weight prior to the dental procedure. This will be done based American Association of Pediatric Dentistry guidelines for the use of local anesthesia.

Treatment:

Drug: Topical anesthetic gel
