Enhancing the Efficiency of EMLA Cream in Palatal Anesthesia for Children

A Study of the Role of Some Drug Delivery Systems in Enhancing the Efficiency of EMLA Cream in Palatal Anesthesia for Children Aged Between 7-11 Years Old

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.

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.
