ABSTRACT
Aims:
The aim of this study was to evaluate the vestibular-palatal diffusion of 4% articaine with epinephrine 1100,000 and 1200,000, in impacted maxillary third molar extractions, without palatal injection. Materials andMethod:
Two hundred teeth were selected from patients age 15 to 46. Patients were divided into 4 groups 1A, were anesthetized with 4% articaine 1100,000 and the surgery was initiated 5 minutes following anesthesia. 1B, used 4% articaine 1100,000 but the surgery was started 10 minutes after anesthesia. 2A, used 4% articaine 1200,000 the surgery was started 5 minutes after. 2B, used 4% articaine 1200,000 but 10 minutes was allowed for anesthetic diffusion before the initiation of in groups (50 extractions each) only buccal vestibule anesthesia was initially administered (i.e. no palatal injections were used).Results:
The rate of sufficient vestibule-palatal diffusion, as determined by the lack of necessity of supplemental palatal anesthesia, was 1A(84%), 1B(98%), 2A(78%), 2B(82%). Chi-square (X2) and residual analyses showed that a higher vestibule-palatal diffusion was obtained using 4% articaine 1100,000 with a period of 10 minutes (p<0.05).Conclusions:
Most of the extractions could be performed only with vestibule anesthesia. However, vasoconstrictor concentration and the time interval between administration of the anesthetic and initiation of surgery did influence buccal vestibule-palatal diffusion of 4% articaine in the extraction models used (AU)
