What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new system called the GentleWave System for root canal treatments. It evaluates patient recovery, post-procedure pain, and treatment satisfaction. The trial targets individuals with apical periodontitis, an infection of the tissue around a tooth's root end. Candidates with a back molar unresponsive to cold or electric tests may qualify. Participants must attend follow-up visits six months and one year after treatment. As an unphased trial, this study provides a unique opportunity to contribute to advancements in dental care.

Do I need to stop my current medications for the trial?

The trial does not specify if you need to stop taking your current medications, but it does exclude people taking corticosteroids.

What prior data suggests that the GentleWave System is safe for root canal procedures?

Research has shown that the GentleWave System is generally safe for root canal treatments. One study reported that 97.3% of patients experienced successful results, with short-term pain comparable to traditional methods. Another study found a 97.4% success rate in healing over six months. The FDA has approved this system, indicating it meets safety standards for dental procedures. Overall, the GentleWave System appears well-tolerated, with no special safety concerns noted in the studies. ^{1 2 3 4 5}

Why are researchers excited about this trial?

The GentleWave System is unique because it uses advanced fluid dynamics and acoustic energy to clean and disinfect root canals more thoroughly than standard treatments. Traditional root canal therapy typically involves manual instruments and chemical solutions, but the GentleWave System enhances cleaning by reaching microscopic spaces within the tooth that are often missed. This precision and efficiency can potentially reduce the time needed for treatment and improve overall outcomes, which is why researchers are excited about its potential to transform endodontic care.

What evidence suggests that the GentleWave System is effective for apical periodontitis?

Research has shown that the GentleWave System is highly effective for root canal treatments. One study found a 97.3% success rate in these treatments, while another reported a 97.4% success rate in healing within six months. The system reduces post-treatment pain and lowers the likelihood of needing the procedure again. It performs well even in challenging cases, such as those involving dead tissue or severe tooth inflammation. This evidence suggests that the GentleWave System is a reliable choice for addressing complex root canal issues. ^{1 2 3 6 7}

Published Research Related to This Trial

In a six-month clinical study involving 89 patients, the GentleWave® System demonstrated a high cumulative success rate of 97.4% for healing molars after root canal treatment.

Two key factors associated with successful healing were identified: the presence of apical periodontitis before treatment and the completion of the procedure in a single visit, highlighting the importance of these factors in treatment outcomes.

The GentleWave System (GWS) demonstrated a significantly higher cleaning efficacy in root canals compared to conventional rotary instrumentation, achieving a 97.2% cleaning rate in certain canal regions versus 67.8% with traditional methods.

In a study involving 45 freshly extracted molars, the GWS effectively reduced residual debris in the mesiobuccal and mesiolingual canals, indicating its potential to improve endodontic treatment outcomes and reduce the risk of persistent infection.

The GentleWave™ System generates negative apical pressures during root canal cleaning, which can enhance safety by reducing the risk of pushing debris beyond the root tip, unlike conventional syringe irrigation that produces positive pressures.

In a study involving extracted maxillary molars, the GentleWave™ System consistently created negative pressures between -13.07 and -17.19 mmHg, while syringe irrigation resulted in positive pressures ranging from 6.46 to 110.34 mmHg, indicating a significant difference in pressure dynamics during the irrigation process.

During a study analyzing dental device adverse events from August 1996 to June 1999, 28,555 reports (10.5% of total) were related to dental devices, with the majority involving injuries (64.4%) and a small number of deaths (0.007%).

Endosseous implants were the most frequently reported dental devices, accounting for over 90% of the reports, highlighting the importance of monitoring these devices for safety and efficacy.

The GentleWave System was found to be significantly more effective at reducing biofilm in the roots of molars compared to conventional rotary instrumentation combined with passive ultrasonic activation, with a notable difference in both apical and middle regions of the roots (p = 0.001).

In the study involving 47 human molars inoculated with Enterococcus faecalis, the GentleWave System showed a significant reduction in biofilm presence compared to untreated controls (p = 0.003), indicating its potential as a superior disinfection method in endodontic treatments.

In a study involving 89 patients, the GentleWave System demonstrated a high cumulative success rate of 97.3% for healing molars after endodontic therapy over a 12-month period.

The system was particularly effective for treating irreversible pulpitis, achieving a success rate of 98.4%, and only 3.8% of patients reported moderate postoperative pain, indicating a favorable safety profile.

From 1996 to 2011, there were 28,046 adverse event reports related to dental devices in the MAUDE database, with 53.5% of these reports concerning endosseous implants, highlighting a significant area of concern in dental device safety.

Among the reported adverse events, there were 66 death reports associated with dental devices, although many lacked sufficient information to confirm the circumstances, indicating a need for better reporting and monitoring systems in dental care.
