Randomized Controlled TrialEfficacy of a Buffered 4% Lidocaine Formulation for Incision and Drainage: A Prospective, Randomized, Double-blind Study.
Incision and drainage of symptomatic emergency patients with facial swelling is painful even after local anesthetics are administered. The purpose of this prospective, randomized, double-blind study was to compare the pain of infiltration and the pain of an incision and drainage procedure of a buffered versus a nonbuffered 4% lidocaine formulation in symptomatic emergency patients presenting with a diagnosis of pulpal necrosis, associated periapical area, and an acute clinical swelling. ⋯ Buffering a 4% lidocaine formulation did not significantly decrease the pain of infiltrations or significantly decrease the pain of the incision and drainage procedure when compared with a nonbuffered 4% lidocaine formulation in symptomatic patients with a diagnosis of pulpal necrosis and associated acute swelling.

Randomized Controlled TrialEvaluation of Root Canal Debridement of Human Molars Using the GentleWave System.
Studies using conventional endodontic protocols show insufficient cleaning of root canal systems, often resulting in persistent infection and treatment failure. The GentleWave System (GWS; Sonendo, Inc, Laguna Hills, CA) has been shown to result in a higher tissue dissolution rate in a study using bovine muscle. The purpose of this study was to compare the debridement efficacy of the GWS with a traditional method for cleaning root canals. ⋯ The GWS showed a significantly greater cleaning capacity and reduction in residual debris within the mesiobuccal and mesiolingual canals of mandibular molars and the mesiobuccal canals of maxillary molars than those cleaned conventionally.
