A History of Proven Efficacy

In a single visit, canals were prepared using two rotary files to a final apical diameter of #20, then followed by the Gentlewave^® Procedure. After obturation, radiographic examination revealed at least two uninstrumented inter-canal isthmi and a lateral canal. At the 6-month recall, radiographs revealed that the GentleWave^® Procedure resulted in complete healing of apical periodontitis.

The exceptional cleaning capability of the GentleWave^® System is evident in this case where a separated instrument, left from a previous treatment in the apical one-third, was successfully removed during the GentleWave Procedure. Inaccessible through standard RCT, the remnant instrument was removed with the Multisonic Ultracleaning® technology of the GentleWave System. The patient, my staff and I were markedly excited at the instrument’s removal and the overall case outcome, all accomplished during a single-visit procedure.

After obturation of a mandibular left second molar, a complex apical anatomy was visible between the mesial and distal canals. This anatomy was not known prior to the GentleWave Procedure.

This case is a beautiful example of the power of the GentleWave^® Procedure with conservative instrumentation. Using VTaper 2H files to retain as much cervical root structure as possible, the Multisonic Ultracleaning^® energy of the GentleWave Procedure allowed us to accomplish our goals for maximum cleaning and disinfection. Notice the secondary anatomy — areas clearly cleaned by the GentleWave^® System — where I never introduced a file.

Upon clinical examination, the mandibular left second premolar (#20) revealed an asymptomatic tooth with no sensitivity to percussion or palpation and Class I mobility. Post GentleWave^® Procedure, at nine-month recall, clinical evaluation showed the tooth was asymptomatic. Radiographic evaluation showed complete bone regrowth and periradicular healing.

An apical delta containing multiple exits was discovered in the palatal canal. The GentleWave^® Procedure cleaned a deep split isthmus between the mesiobuccal canal and palatal canal, which otherwise may have been left uncleaned and unfilled.
