Abstract
Objective: To compare the anesthetic effect of a non commercial eutectic mixture of 4% lidocaine/ prilocaine (PLO 4%) and 20% benzocaine gel (Hur- ricaine®), as topical anesthetic, prior to inferior al- veolar nerve block and buccal infiltration anesthesia in 5 - 12 year old children. Study design: Infiltrative anesthesia was applied in 50 children, divided in two groups (n = 25) using PLO 4% and Hurricaine® as topical anesthesia prior to infiltration. Physical reac- tions were registered using the Sound-Eyes- Motor Scale. Physiological changes expressed by ar- terial pressure and heart rate. Subjective pain re- sponse was scored on a Facial Image Scale. Physical physiological and subjective response was related to the type of topical anesthetic, age and sex using χ 2 and Mann-Whitney U test. Results: Physical resp- onses to puncture were similar and localized in the state of comfort with both anesthetics. Girls showed more ocular response than boys. Subjective pain perception and physiological reactions showed no anesthetic- or sex-related differences, except for heart rate before and after the procedure which was significantly higher in girls. Conclusions: PLO 4% showed the same capacity as Hurricaine® in reduc- ing pain response to needle puncture. Girls ex- pressed more needle puncture-related pain than boys. The young children showed most prior comfort and less discomfort to the puncture than older children.
Highlights
In-office dental procedures are associated with discomfort and pain for most people
The anesthetics used in the study were 20% benzocaine gel (Hurricaine®) and 4% lidocaine and prilocaine ointment (LPO 4%), both prepared for this study in single dose 0.5 gram tubes
LPO4% is a non commercial eutectic mixture of 4% lidocaine and prilocaine. Both these anesthetics, which belong to the amide family, are less likely to provoke allergic reactions than ester anesthetics and are extremely similar to the anesthetic used for infiltration anesthesia (2% lidocaine with epinephrine at 1:100,000), an amide
Summary
In-office dental procedures are associated with discomfort and pain for most people. For the part of the population which has to visit the dentist, this association generates fear and anxiety. If the patient is a child, controlling any discomfort and/or pain in dental procedures is fundamental and key to ensuring pleasant, safe and effective treatment. For this purpose local anesthetics (LA) are routinely used in pediatric dentistry [1]. Together with cavity preparation by turbine, the application of anesthesia is one of the procedures which generate the greatest fear and anxiety in pediatric patients and dentists themselves [3]. A basic technique in handling patient behavior because an effective anesthetic technique will provide a relaxed patient, quality, effective work and satisfied parents
