68 healthy children from the Department of Pediatric Dentistry at Damascus University who require treatment for their primary maxillary second molars will be randomly assigned into one of two groups: experimental or control groups. In the experimental group, a lidocaine hydrochloride-epinephrine hydrochloride nasal spray will be applied to anesthetize upper second molar before the commencement of treatment.
To assess the efficacy of this kind of anesthesia, a specific scale will be used by an external observer after capturing some video files of the performed treatment.
To assess the safety of this procedure, vital signs will be recorded before and after treatment.
Acceptance of the nasal spray will be recorded based on the child's behavior before and after treatment using Frankl scale.
If anesthesia was not sufficient to proceed with the procedure, a rescue anesthesia would be used. Rescue anesthesia consists of an infiltration injection of lidocain hydrochloride 2% with epinephrine hydrochloride (1:100,000). In the control group, an intra-oral lidocaine-epinephrine injection will be applied due to treatment. Safety, efficacy and acceptance will be assessed in the same manner to what is performed in the experimental group.
The most common method for anesthetizing maxillary teeth is infiltration injection of an anesthetic agent. This approach carries several disadvantages. First is the child's fear of pain. Infection is also a risk for providers, through exposure to blood-borne pathogens via needle stick.
Fear of a painful dental injection and subsequent avoidance behavior are significant barriers to regular visits to the dentist.
Importantly, patients' fear of injections can delay needed dental care. Surveys indicate that 30-40 million people in the US avoid going to the dentist because of fear of pain and anesthetic injections.
Therefore an anesthetic procedure that would avoid the discomfort of a local anesthetic injection thus obviating fear and anxiety about receiving a "shot," would greatly benefit dental patients. Further, for procedures involving more than one maxillary tooth on the same side, a trans-nasally applied anesthetic agent that could anesthetize multiple maxillary teeth at once instead of use of repeated infiltration injections would be a major convenience for patients and dentists.

A local anesthetic that is similar pharmacologically to LIDOCAINE. Currently, it is used most often for infiltration anesthesia in dentistry. (From AMA Drug Evaluations Annual, 1992, p165)
A colorless liquid with a sharp burning taste and slight odor. It is used as a local anesthetic and to reduce pain associated with LIDOCAINE injection. Also, it is used in the manufacture of other benzyl compounds, as a pharmaceutic aid, and in perfumery and flavoring.
A local anesthetic that is chemically related to BUPIVACAINE but pharmacologically related to LIDOCAINE. It is indicated for infiltration, nerve block, and epidural anesthesia. Mepivacaine is effective topically only in large doses and therefore should not be used by this route. (From AMA Drug Evaluations, 1994, p168)
Antiarrhythmic agent pharmacologically similar to LIDOCAINE. It may have some anticonvulsant properties.
