A History of Proven Efficacy

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.

A 31-year-old female patient presented to our clinic with a chief complaint of pain in the lower right jaw. Tooth #30 was diagnosed with pulp necrosis/symptomatic apical periodontitis.

By the end of canal instrumentation, four canals had been located: two in the mesial and two in the distal roots. Following the GentleWave^® Procedure, two tiny orifices became noticeable between MB and ML canals; they turned out to be two mid-mesial canals. Pre-op CBCT had not hinted at the presence of mid-mesial canals.

The immediate post-op radiograph shows the filling of six canals with gutta-percha and BC Sealer™. The two mid-mesial canals join each other at the apical half, and all four canals in the mesial root join at the apical 3 mm level.

“Without the cleaning ability of the GentleWave Procedure, I would have missed the additional two middle canals, which could have resulted in a persistent infection.”

A 65-year-old female with no clinical symptoms was referred by her dentist, who noticed radiographic signs of bone loss surrounding the roots of her molar. In a single visit, the canals were cleaned and disinfected with the GentleWave Procedure. Eight weeks later, the periodontal reading at the distobuccal root surface measured 2 mm, and periapical imaging revealed extensive bone regeneration. Continued bone regeneration was evident at 3-month, 5-month and 13-month recalls.

A mandibular right first molar with a large carious lesion on the disto-occlusal surface was treated with the GentleWave® System. Signs of healing were observed within three months after the initial root canal treatment.

A tooth’s survivability is greatly reduced when there’s a crack at or near the level of its roots. In this case, tooth #31 was cracked with a diagnosis of pulpal necrosis and symptomatic apical periodontitis. Initial recommendation was tooth extraction, but the patient’s preference was to save the tooth. The GentleWave® Procedure was our best approach to preserve as much of the remaining structural integrity of the root. In a single visit and with minimal instrumentation, the GentleWave Procedure thoroughly cleaned and disinfected the root canal system to promote tooth healing.

"With minimal instrumentation, I was able to depend on the GentleWave® Procedure to thoroughly disinfect the root canal system. And for healing to occur in the presence of a crack is even more impressive."

At 6-month recall, the results are impressive. The patient is asymptomatic and showing excellent healing.

Six months post-op, the periradicular bone appeared to have completely healed. The patient resumed active orthodontic treatment. This case illustrates the power of a single-visit GentleWave® Procedure in effectively cleaning and disinfecting the root canal system and promoting rapid healing.
