Minimally invasive root canal treatment with heated sodium hypochlorite for tooth healing

Minimal Instrumentation With Intracanal Heating ad Activation of Sodium Hypochlorite for

NA · Saint-Joseph University · NCT06461728

This study is testing a new way to do root canal treatment using heated sodium hypochlorite to see if it helps heal single-rooted teeth better than the traditional method for people with tooth pain.

What this trial studies

This study evaluates the effectiveness of a minimally invasive approach to root canal treatment that combines intracanal heating and activation of sodium hypochlorite in treating asymptomatic apical periodontitis in single-rooted teeth. A total of 32 teeth will be randomly assigned to either a conventional or conservative technique group. The conventional group will utilize rotary instrumentation and standard sodium hypochlorite irrigation, while the conservative group will employ a prototype device for heating and activating the sodium hypochlorite. The study aims to assess the healing outcomes based on clinical and radiological evaluations.

Who should consider this trial

Good fit: Ideal candidates include healthy adults with single-rooted teeth exhibiting pulp necrosis and asymptomatic apical periodontitis.

Not a fit: Patients with multiple canals, previous root canal treatments, or significant anatomical variations may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved healing outcomes for patients with periapical lesions and reduce the need for more invasive procedures.

How similar studies have performed: While this specific approach is novel, similar studies have shown promise in improving endodontic outcomes through advanced irrigation techniques.
