PONTES, Caetano Guilherme Carvalho et al. Assessment of clinical and cardiovascular effects of use of ropivacaine and lidocaine in impacted lower third molar surgery. Rev. cir. traumatol. buco-maxilo-fac. [online]. 2011, vol.11, n.4, pp. 73-82. ISSN 1808-5210.

Ropivacaine is widely used in medicine for epidural and regional anesthesia due to its long duration and low degree of toxicity. This drug has also been increasingly used in dentistry. The aim of the present study was to assess the clinical and cardiovascular effects of the use of ropivacaine (7.5 mg/ml) without a vasoconstrictor and lidocaine 2% with adrenalin (1:100,000) in a randomized, double-blind, clinical trial involving a sample of patients submitted to two separate surgical interventions for the removal of impacted lower third molars. The results demonstrate that lidocaine has a shorter latency time in comparison to ropivacaine (3.67 minutes versus 9.38 minutes). Ropivacaine has greater duration than lidocaine. Postoperative pain symptoms were more intense following surgery employing lidocaine. Neither drug exhibited adverse effects with regard to significant cardiovascular alterations. In conclusion, ropivacaine is a viable alternative for use in dental procedures that require a longer surgical time and analgesic action in the immediate postoperative period
