Evaluation and comparison of 2 needle models in XXXX during truncal block of the @entity129 .

@entity1 @entity129 @entity101 @entity1503 @entity1442 @entity616
PURPOSE: We conducted a study to determine the possible differences in @entity1503 between 2 needles of the same length and external gauge but with different internal gauges during truncal block of the @entity129 . The @entity1442 was that increased @entity1503 may be expected with larger internal gauge needles. MATERIALS AND METHODS: Four clinicians subjected 346 @entity1 to @entity616 and infiltrating anesthesia of the buccal nerve trajectory for the surgical or conventional extraction of the lower third molar. A nonautoaspirating syringe system with 2 types of needle were used: a standard 27-gauge x 35-mm needle with an internal gauge of 0.215 mm and an XL Monoprotect (manufactured by Sofic, Mazamet, France, and distributed by Laboratorios Inibsa, Barcelona, Spain) 27-gauge x 35-mm needle with an internal gauge of 0.265 mm. The following information was recorded for each @entity1 : needle type, gender, anesthetic technique (direct or indirect truncal block) and the number of bone contacts during the procedure, the @entity1 -extraction side, the operator performing the technique, and @entity1503 (either positive or negative). RESULTS: No significant differences (P <.05) were observed on contrasting the @entity1503 positivity with the internal gauge of the needles. Likewise, no significant differences were seen on correlating aspiration to the anesthetic technique used, the number of bone contacts, the operator, or the @entity1 -extraction side. Blood aspiration was observed in 8.7% of cases. CONCLUSIONS: No significant differences were recorded in @entity1503 and internal gauge, operator, @entity1 -extraction side, or the anesthetic technique involved. Consequently, our initial @entity1442 can be rejected, because no @entity101 was observed for greater internal gauges.
