What is the purpose of this trial?

This trial aims to evaluate the effectiveness of the GentleWave system, a new technology for root canal treatment, in cleaning and treating teeth during procedures. Researchers will assess its effectiveness by examining results in real-life situations. Candidates for this trial include individuals who have opted for tooth extraction over other dental treatments. The study excludes teeth with fractures, previous root canal treatments, or severe damage. As an unphased trial, participants have the opportunity to contribute to innovative dental research and potentially benefit from cutting-edge technology.

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

The trial information does not specify whether you need to stop taking your current medications.

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

Research shows that the GentleWave procedure is usually easy for patients to handle. Studies have found that it cleans root canals effectively without traditional dental tools, preserving the tooth's structure. However, like any medical procedure, it carries some risks. Certain health conditions or tooth shapes might make the procedure less suitable for some patients. While side effects can occur, they are uncommon. Patients should consult a dentist to determine if this procedure is appropriate for them. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the GentleWave system for root canal treatment because it offers a unique approach compared to traditional methods. Unlike standard root canal treatments that rely on manual cleaning and mechanical instruments, GentleWave uses advanced fluid dynamics and acoustic energy to clean and disinfect the root canal system more thoroughly. This method aims to better reach complex areas within the tooth that are typically hard to clean, potentially leading to improved outcomes and less post-procedure discomfort. Additionally, the GentleWave system could reduce the time required for the procedure, making it a more efficient option for both patients and dental professionals.

What evidence suggests that the GentleWave System is effective for root canal treatment?

Research shows that the GentleWave system, which participants in this trial will receive, performs effectively for root canal treatments. Studies have found it successful in over 97% of cases, with most patients healing well and feeling better. High healing rates are reported at both 6 and 12 months after treatment, demonstrating its long-term effectiveness. Patients experience similar pain relief compared to other standard treatments. This new technology is designed to be less invasive, aiding in quick and comfortable recovery. Overall, GentleWave presents a promising option for those needing root canal therapy. ^{2 3 4 6 7}

Are You a Good Fit for This Trial?

This trial is for adults who have chosen to have a tooth extracted rather than undergo other dental treatments. It's not suitable for teeth with severe structural damage, root fractures, or those that previously had root canal treatment.

Inclusion Criteria

Only teeth that patient decided to have the extraction done instead of having any other type of dental treatment and teeth extracted at patient's petition.

Exclusion Criteria

You have severe damage to your teeth.

You have teeth with fractures in the roots or that have had root canal treatment before.

Participants must be adults and not children.

Published Research Related to This Trial

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.

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.

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.

In a randomized clinical trial comparing the GentleWave System (GWS) to standard irrigation methods in endodontic treatment, both groups experienced similar rates of postoperative pain, with 72.2% in the standard group and 83.3% in the GWS group reporting pain.

Despite no significant difference in pain incidence or intensity between the two methods, both groups showed a statistically significant decrease in pain over time after treatment, indicating that pain generally lessens as time passes.

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.

The GentleWave System (GWS) combined with either minimally invasive technique (MIT) or conventional instrumentation technique (CIT) was found to be the most effective in removing Enterococcus faecalis lipoteichoic acid (LTA) from infected root canals, with both methods showing similar efficacy.

In a study involving 60 extracted human teeth, GWS treatments resulted in more root canals having undetectable levels of E. faecalis LTA after treatment compared to other methods, highlighting its potential for improved infection control in endodontic procedures.
