Enhancing the Efficiency of EMLA Cream in Palatal Anesthesia for Children

The aim of this study is to Avoid traditional palatal local injections when extracting upper primary teeth through enhancing the efficiency of EMLA cream by using drug delivery systems (permeability enhancer (DMSO), oral patches and micro-needle patches) for palatine injection.

Group 1: Conventional local palatine injection (control group). Group 2: EMLA cream only. Group 3 :chemical permeability enhancer DMSO with EMLA cream. Group 4: Oral patches with EMLA Cream. Group 5: Micro-needle patches dissolved with EMLA Cream.

About this study

The insertion of the needle and the infusion of the anesthetic solution into the palate often uncomfortable for the children and their acceptance of dental treatment. Therefore, there is a need for studies to find ways to replace the palatine injection in the modern dentistry.

Effectiveness of Compound surfactant drugs (EMLA) have strong activity on the palatine tissues. Therefore, it will be chosen as an alternative to the traditional ones and will be enhanced by one of the drug delivery systems (physical/chemical).

Decreased permeability of the palatine mucosa is a major reason behind using drug delivery systems to reach an effective therapeutic level.

To our knowledge, this research will be the first which will be used a method of drug delivery systems to replace traditional palatal needle.

Treatment and study plan

Conventional local palatine injection

Other

Conventional palatal injection with anesthetic (lidocaine HCL2% with Epinephrine 1:80000, Korea) Then the palatal probe will be performed with a dental probe in contact with the bone to estimate anesthetic effectiveness

EMLA cream only

Drug

Emla cream will be applied at a distance of 1 mm from the palatine gingival edge by cotton buds for 3 minutes within the application area 14*14 mm and the mouth will be open throughout the procedure and the saliva will be controlled by a saliva absorbent. Then the palatal probe will be performed with a dental probe in contact with the bone to estimate anesthetic effectiveness.

chemical permeability enhancer DMSO with EMLA cream

Drug

Adding 10 g of EMLA cream 5%, 1,026 g of DMSO 100% and it will be applied with cotton bud for a period of 3 minutes while the child is opening his mouth and the saliva is controlled by saliva absorbent. Then the palatal probe will be performed with a dental probe in contact with the bone to estimate anesthetic effectiveness.

Oral patches with EMLA Cream

Drug

EMLA cream 5% will be applied at a distance of 1 mm from the palatal gingival edge using an oral patch 14*14 mm for 3 minutes and the Mouth will be closed throughout the procedure. Then the palatal probe will be performed with a dental probe in contact with the bone to estimate anesthetic effectiveness

Micro-needle patches dissolved with EMLA Cream

Drug

EMLA cream 5% will be applied at a distance of 1 mm from the palatal gingival edge using an micro-needle patch 14*14 mm, 0,25 micron for 3 minutes and the Mouth will be closed throughout the procedure. Then the palatal probe will be performed with a dental probe in contact with the bone to estimate anesthetic effectiveness.

Primary outcomes

  1. Changes in the values of each of the heart rate and oxygen rate

    Time frame: On application of the substance

    The heart and oxygen rate will be recorded by pulse oximeter

  2. Evaluation conventional local palatine injection

    Time frame: On palatal probing

    The heart and oxygen rate will be recorded by pulse oximeter

  3. Evaluation conventional local palatine injection

    Time frame: On extraction

    The heart and oxygen rate will be recorded by pulse oximeter

  4. Pain levels using self-reported Wong-Baker faces pain scale

    Time frame: On application of the substance

    0= "no hurt", 2= "hurts a little bit", 4="hurts a little more", 6= "hurts even more", 8= "hurts a whole lot", 10= "hurts worst"

  5. Pain levels using self-reported Wong-Baker faces pain scale

    Time frame: On palatal probing

    0= "no hurt", 2= "hurts a little bit", 4="hurts a little more", 6= "hurts even more", 8= "hurts a whole lot", 10= "hurts worst"

  6. Pain levels using self-reported Wong-Baker faces pain scale

    Time frame: On extraction

    0= "no hurt", 2= "hurts a little bit", 4="hurts a little more", 6= "hurts even more", 8= "hurts a whole lot", 10= "hurts worst"

  7. Pain levels using FLACC scale

    Time frame: On application of the substance

    0 = Relaxed and comfortable, 1-3 = Mild discomfort, 4-6 =Moderate pain, 7-10 = Severe discomfort/pain

  8. Pain levels using FLACC scale

    Time frame: On palatal probing

    0 = Relaxed and comfortable, 1-3 = Mild discomfort, 4-6 =Moderate pain, 7-10 = Severe discomfort/pain

  9. Pain levels using FLACC scale

    Time frame: On extraction

    0 = Relaxed and comfortable, 1-3 = Mild discomfort, 4-6 =Moderate pain, 7-10 = Severe discomfort/pain
