ABSTRACT

Aim of the study. The goal of buffering is to shorten the latency time of the anaesthesia and reduce the duration time of the anaesthesia.

Materials and methods. The study included 43 patients undergone mandibular nerve block with buffered and non-buffered 2% lidocaine. The researched parameters were latency period in seconds (speed of onset of anaesthesia) and anaesthesia duration time measured in minutes.

Results. When latency time of buffered and non-buffered 2% lidocaine was investigated, results revealed statistically significant difference in advantage of buffered anaesthetic. No statistically significant difference was determined when assessed duration of anaesthesia.

Conclusions. Buffered 2% lidocaine provided faster speed of anesthesia than non-buffered analog.
