The effectiveness of articaine in mandibular facial infiltrations

Abstract

Four percent articaine local anesthetic has been successfully used to attain local anesthesia for dental procedures. Mandibular block anesthesia may consume longer time to attain and have a higher failure of local anesthesia compared to infiltration. Mandibular facial infiltration has been reported to successfully attain effective local anesthesia for dental procedures. This study involved only several tooth sites and found that 1.8 cc of 4% articaine facial infiltration in the mandible may be effective when the facial mandibular cortex is <2.0–3.0 mm. A waiting time of 5–10 minutes may be required for effective anesthesia. An additional 1.8 cc of dose may be required to attain anesthesia if an initial 1.8 cc of dose fails. The need for additional anesthetic may be predicted by a measurement of the facial cortex using cone beam computerized tomography. A study of mandibular sites is needed to delineate the anatomical dimensions, density of cortical bone, and apical neural location for ensuring successful local anesthetic infiltration.

Efficacy of Articaine Versus Lidocaine, as a Buccal Infiltration Combined With Intraligamentary Injection, in Mandibular Molars With Irreversible Pulpitis- A Clinical Trial Study

“…Lidocaine 2% as a buccal infiltration showed lower success as compared to that of articaine. 5 Intraligamentary injections are one of the supplemental injections which raise the success rate to a reliable extent. Thus, the purpose of this study was to compare the anaesthetic success rate of buccal infiltration combined with intraligamentary injections of 4% articaine and 2% lidocaine in mandibular molars with irreversible pulpitis.…”

Local anesthesia for mandibular third molar extraction

“…Nonetheless, it is believed the varying success rates reported of infiltration anesthesia using articaine in mandibular third molar extraction [ 30 31 ] are due to various mandibular cortical bone thicknesses. Flanagan reported that the cortical bone thickness of 2–3 mm is the cutoff point for successful anesthesia in mandible posterior infiltration anesthesia, suggesting the possibility of employing infiltration anesthesia using articaine alone to achieve anesthesia [ 32 ]. In other words, infiltration anesthesia may provide sufficient anesthesia in dental extractions for patients with a thin mandibular cortical bone.…”

Hueso Cortical en Sínfisis Mandibular de Sujetos de Clase I

“…Flanagan (2015), estudió el tiempo del efecto anestésico y su relación con el hueso cortical, indicando que sujetos con tamaño de cortical promedio de 2,12 mm presentaban sensibilidad al estimulo eléctrico luego de 5 min de aplicado la anestesia infiltrativa local mientras que sujetos con promedios de 2,0 mm no presentaban ningún tipo de sensibilidad en el mismo tiempo de evaluación, concluyendo que el tamaño de cortical era uno de los motivos para mayor o menor tiempo de acción del anestésico local. Lee et al (2015), realizaron una interesante investigación donde observaron sujetos con oclusión dentaria sin anomalías de posición; identificaron que a nivel del incisivo central el tamaño de cortical bucal fue de 1,8 mm; a nivel de incisivo lateral, 2,0 mm y a nivel del canino, 2,3 mm.…”
