Abstract

Objective: This study aims to evaluate the onset, duration, and quality of anesthesia, along with the duration of analgesia, in
seventy-five randomly selected patients undergoing oral and maxillofacial surgery.
Methods: Patients were divided into three groups receiving local anesthesia with intraoral Ropivacaine. Onset of anesthesia
was assessed verbally, and depth was measured using an electric pulp tester. Anesthesia quality was rated on a 7-point scale,
and duration was determined by pain perception lapse.
Results: Onset durations for subjective symptoms were 0.75% (1.240.52± minutes), 0.50% (1.801± minute), and 0.20%
(2.680.90± minutes). Objective symptom onsets were 0.75% (2.660.65± minutes), 0.50% (3.91.32± minutes), and 0.20%
(6.841.26± minutes), with faster onset at 0.75%. Mean anesthesia duration was longest for 0.75% (8.021.11± hrs), and analgesia
duration was also longest for 0.75% (4.493.29± hrs). Nine patients in 0.75% and eight in 0.50% reported no post-procedure
pain, while all in 0.20% experienced pain. Anesthesia duration significantly differed (p=0.001), but analgesia duration did not
(p=0.09).
Conclusion: This study demonstrates that anesthesia onset is faster and duration is longer with higher concentrations of
Ropivacaine. While anesthesia duration significantly varied among concentrations, analgesia duration did not show significant
differences.
