Clinical Trial Summary

Everyday practice in dentistry is based on giving the painless injection and achieving adequate local anesthesia. Various techniques of reducing injection pain in children can be broadly categorized as psychological and physical. The psychological approach includes behavior management techniques, physical means and other recent techniques such as computer controlled anesthesia, electronic dental anesthesia, and so forth. However, none of these techniques have been successful in eliminating pain, fear and anxiety in children.

Direct palatal injection technique is difficult to administer without significant pain or discomfort since there is little tissue space at these sites between the mucosa and the underlying periosteum. Studies conducted on indirect palatal injection technique (intrapapillary) revealed that it reduces the pain of palatal injection with the same efficacy of anesthesia during extraction.

The desirable method to evade pain during palatal injection is just not to have one.

Maxillary molars removal without palatal or multiple injections is possible due to relatively thin porous bone of posterior buccal maxilla that facilitates the diffusion of local anesthetic.

Clinical Trial Description

The provision of intraoral palatal anesthesia can be potentially more painful for the patient when compared to other sites of the oral cavity, as palatal tissues are tightly bound to the hard palate with limited tissue space between it and the periosteum . As the injection is given, pressure builds up within the palatal tissues causing pain.

Studies conducted on indirect palatal injection technique (intrapapillary) revealed that it reduces the pain of palatal injection with the same efficacy of anesthesia during extraction.

The desirable method to evade pain during palatal injection is just not to have one. So studies was made to evaluate the single buccal injection and its efficiency during extraction of maxillary teeth. The relatively thin porous bone of posterior buccal maxilla facilitates the diffusion of local anesthetic,as well as articaine can diffuse through soft and hard tissues more reliably than other LA so that maxillary buccal infiltration of articaine provides palatal soft tissue anesthesia.Therefore single injection eliminates the need for multiple painful injections. ;
