“…The needles used in this study for administration of local anesthesia were 27 gauge. A comparison between the 25G and 27G gauges needles was done by Carr and Horton, 10 who reported no difference in pain perception by patients for administration of local anesthesia in the oral cavity.…”

The aim of the present study was to compare the effects of a topical anesthetic to a placebo on pain perception during administration of local anesthesia in 2 regions of the oral cavity. A split-mouth, double-blind, randomized clinical trial design was used. Thirty-eight subjects, ages 18-50 years, American Society of Anesthesiologists I and II, received 4 anesthetic injections each in regions corresponding to the posterior superior alveolar nerve (PSA) and greater palatine nerve (GPN), totaling 152 sites analyzed. The side of the mouth where the topical anesthetic (benzocaine 20%) or the placebo was to be applied was chosen by a flip of a coin. The needle used was 27G, and the anesthetic used for administration of local anesthesia was 2% lidocaine with 1:100,000 epinephrine. After receiving the administration of local anesthesia, each patient reported pain perception on a visual analog scale (VAS) of 100-mm length. The results showed that the topical anesthetic and the placebo had similar effects: there was no statistically significant VAS difference between the PSA and the GPN pain ratings. A higher value on the VAS for the anesthesia of the GPN, relative to the PSA, was observed for both groups. Regarding gender, male patients had higher values on the VAS compared with female patients, but these differences were not meaningful. The topical anesthetic and the placebo had similar effects on pain perception for injection of local anesthesia for the PSA and GPN.

“…However, no difference was noted from placebo in the posterior areas of the maxilla or in the inferior alveolar nerve. According to Carr and Horton, 10 there was no difference in pain threshold reported by patients when using needles of 25 and 27 gauge for administration of local anesthesia in the oral cavity.…”

Para el registro de los datos se asignaron dos estudiantes que se encargaron de llenar el formato de captura de datos con ayuda de oxímetro de pulso (Fingertip pulse oximeterMod.…”

“…[2][3][4][5][6] De acuerdo con Malamed 7 la aplicación correcta del anestésico tópico permitirá la penetración de la aguja dental en la membrana de la mucosa oral de una manera indolora. Esta teoría ha sido apoyada por otros estudios en donde se comparó un agente anestésico con un placebo, dando como resultado que los agentes anestésicos utilizados fueron altamente eficaces y seguros al reducir el dolor a la punción; [8][9][10][11][12][13][14][15][16][17] sin embargo Kincheloe, en otro estudio, no encontró diferencias estadísticamente significativas. 18 Al respecto Martin y sus colaboradores sugieren que los anestésicos tópicos tienen más efecto psicológico que farmacológico.…”

Eficacia de dos anestésicos tópicos, de uso dental, en pacientes pediátricosResumen INTRODUCCIÓN: el dolor a la punción durante la anestesia dental local puede disminuir con ayuda de un anestésico tópico, evitando asociar la anestesia dental con el dolor.OBJETIVO: comparar la eficacia de dos anestésicos tópicos: a) lidocaína/prilocaína al 5% (parche) y b) benzocaína al 20% (gel) para disminuir la sensibilidad a la punción en la mucosa oral. MATERIALES Y MÉTODOS:se diseñó un estudio clínico comparativo con 60 pacientes entre 3 y 9 años de edad, divididos en dos grupos experimentales; la punción se realizó con aguja dental calibre 30. La intensidad del dolor se evaluó mediante la escala SEM (sound, eyes, motor) contrastando los resultados con los cambios fisiológicos: saturación de oxígeno y pulso.RESULTADOS: 60 niños de ambos géneros, de 3 a 9 años de edad, participaron en el estudio. La variable dolor-moderado se presentó en 15% de la población estudiada (9 participantes) de los cuales 6 fueron femeninas y 3 masculinos, todos pertenecían al grupo benzocaína. El análisis estadístico arrojó una mayor eficacia de lidocaína/ prilocaína (P=0.025).CONCLUSIONES: la aplicación de lidocaína/prilocaína al 5% es más eficaz para reducir el dolor que produce la punción de la aguja de anestesia dental.PALABRAS CLAVE: anestésicos tópicos, EMLA, benzocaína, dolor, anestesia dental. Abstract BACKGROUND: Pain puncture during local dental anesthesia, can be reduced using a topical anesthetic, avoiding dental anesthesia associated with pain. Maldonado

“…Assessment of pain after injection of local anesthetic may result in higher pain score. 16 Hence, care was taken in our study to standardize the procedure of injection, such as wiping the mucosa dry before topical application to maximize the effect of the topical anesthetic, application time of 3 minutes, use of smaller gauge needle, slow rate of injection, verbal suggestion and behavior management techniques. This standardization was done to minimise pain as well as variation between the groups.…”

Aim:To compare the efficacy of 15% lignocaine spray and 8% lignocaine gel as a topical anesthetic, in reducing pain, during buccal infiltration in children. Materials and methods:Forty-two patients aged between 7 and 12 years requiring restorative procedures/extraction/pulp therapy of primary/ permanent teeth in the maxillary arch, under buccal infiltration anesthesia were selected for the study. The participants were randomly allocated into 2 groups of 21 each. In group A, 8% lignocaine gel and in group B, 15% lignocaine spray was applied prior to buccal infiltration. Pain was assessed using Wong-Baker faces pain rating scale (WBFPRS) and faces legs activity cry and consolability (FLACC) painscale. Results:Pearson's chi-square test revealed that there was no significant difference in the FLACC scores of the two groups (p = 0.54). Independent t-test demonstrated that there was no significant difference in Wong-Bakers faces pain score between the two agents (p = 0.07). Conclusion:There is no significant difference in the efficacy of 15% lignocaine spray and 8% lignocaine gel as a topical anesthetic in controlling pain during buccal infiltration anesthesia, in children.
