Material y métodos: Diecinueve adultos voluntarios recibieron 1.8 mililitros de lidocaína al 2% con epinefrina 1:80,000 con una técnica infraorbitaria intraoral. Los investigadores usaron un electric pulp tester (vitalómetro) para medir la anestesia pulpar en incisivos y premolares maxilares. Los participantes informaron sobre anestesia en tejidos blandos, y molestias durante la inyección además de que valoraron el tiempo de inicio de la anestesia y la duración de la misma. Los autores analizaron los datos usando el programa estadístico STATA 9®.  Resultados: La mayoría de los sujetos tenía 21 años (30%), el sexo más común fue el sexo femenino (n = 12-60%). Los autores evaluaron con escala visual análoga (VAS), la percepción del dolor al momento de aplicar la anestesia, encontrando que el 57.9% de los pacientes (n = 11) lo catalogaron como moderado (escala de 3-6). Al evaluar el éxito anestésico, observaron un mayor número de episodios en el canino y el primer premolar (57.9%, n = 9 - IC 95%), Los autores observaron un importante número de fallas en la anestesia pulpar de incisivos centrales y laterales (100-84.2%, respectivamente). El inicio de la anestesia fue a los 12-19 minutos, siendo el canino el de mayor número de reportes con un 47.4%. La incidencia de sensación subjetiva de anestesia de los tejidos blandos en piel de párpado, ala de la nariz y piel de labio superior fue del 100%, los autores observaron que el 100% de los sujetos la calificaron como desagradable (VAS).  Conclusiones: La técnica infraorbitaria produce anestesia exitosa en sólo el 57.9% de los caninos y primeros premolares maxilares; es ineficaz para anestesiar incisivos centrales y laterales, luego de ser evaluada con un riguroso test de vitalometría, se produce anestesia de tejidos blandos que es catalogada como incomoda. Los autores consideran que la utilidad de la técnica infraorbitaria en odontología es cuestionable y se deben considerar otras técnicas para los incisivos y premolares maxilares.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ Objectives: The authors conducted a clinical-trial, uncontrolled study to determine infraorbital nerve block effectiveness.  Material and methods: Nineteen adult volunteers received 1.8 mL of lidocaine 2% with epinephrine 1:80,000 with an intraoral, infraorbital nerve block. Researchers used an electric pulp tester to measure pulp anesthesia in maxillary incisors and premolars. Participants reported soft tissue anesthesia and discomfort during the injection procedure; anesthesia onset time and its duration were also assessed and analyzed. Authors analyzed data using STATA statistical program 9®.  Results: Most of the subjects in our trial were 21 years old (30%); the number of female participants (n = 12 - 60%) was greater than that of male participants. Authors evaluated pain perception when injecting anesthesia with a visual analogue scale (VAS), finding that 57.9% of patients (n = 11) categorized the pain as moderate (in a scale of 3-6). When assessing anesthesia success, it was observed that a greater number of canine teeth and first premolars (57.9%, n = 9 - CI 95%) were anesthetized. The authors also observed a significant greater number of nonresponse (non-anesthetized) cases in central and lateral incisors (100-84.2%, respectively). Anesthesia onset was at 12 to 19 minutes, with canines exhibiting the largest number of anesthetized reports with 47.4%. There was a 100% incidence of subjective feeling of soft tissue anesthesia in lower eyelid skin, skin of the nose and skin of the upper lip. Authors noted that 100% of the subjects rated it as unpleasant (VAS).  Conclusions: Infraorbital anesthesia technique achieved successful anesthesia in only 57.9% of upper canines and first premolars; it proved ineffective for anesthetizing central and lateral incisors. This was demonstrated after these teeth were evaluated using rigorous pulp vitality testing. Soft tissue anesthesia occurred and it was classified as uncomfortable. Authors consider that usefulness of infraorbital nerve block technique in dentistry was questionable.]]></p></abstract>
