This is a clinical study that will investigate the occurrence of post-operative discomfort following the use of the Gentlewave System for root canal disinfection and irrigation. Assessment of discomfort level will be via a visualized analog pain scale.
Once a tooth reaches a level of inflammation where healing can no longer occur or when the pulp space begins to go through necrosis, root canal treatment is indicated. The goal of root canal therapy is to clean, shape, disinfect, and obturate all canal systems within the tooth. Schilder's mechanical and biological objectives for cleaning and shaping includes: preparing a continuous tapering root canal funnel from access to apex, cross-sectional diameters should be wider at every point as you move coronally, the preparation should occupy as may planes as presented by the original canal and should follow the shape of the original canal, the apical foramen should remain in it is original spatial relationship to bone and to root surface, the apical opening should be kept as small as practical in all cases, complete cleaning and shaping in one appointment, procedures should be confined to the roots themselves, necrotic debris should not be forced beyond the foramina, all tissues should be removed from root canal space, and sufficient space for intracanal medicaments and irrigation should be created. Traditionally, the standard protocol for cleaning and shaping is completed using multiple hand or rotary files. Siqueira discovered that the factors that are commonly responsible for post-operative or interappointment pain include mechanical preparation and obturation beyond the apex, bacterial insults not present in the primary infection, and chemical extrusion of irrigant materials beyond the apex. Post-operative pain can occur hours to days following root canal procedures. Irrigation dissolves organic material and kills microbes. It also helps prevent the binding of instruments, improves the cutting effectiveness of files, dissolves tissue, and cools the instrument and tooth. The most common endodontic irrigant is sodium hypochlorite. Sodium hypochlorite is an alkaline fluid with a pH of approximately 11-12. It hydrolyzes proteins and causes hemolysis of red blood cells which leads to the dissolution of vital, as well as necrotic tissue. Upon contact of organic debris, hypochlorus acid forms which disrupts bacterial metabolism by oxidizing the sulfhydryl group of bacterial enzymes. The purpose of this study is to determine whether a new treatment modality for cleaning and disinfecting the root canal system will significantly affect the occurrence and severity of post-operative pain. Patients will be randomly divided into two groups, control and research. The control group will have the standard root canal procedure. The research group will have a root canal treatment that includes irrigation and disinfection with the Gentlewave system, thus eliminating the need for multiple rotatory files and multiple irrigation steps. Patients will be asked to complete a visual analog pain scale rating for pretreatment pain, as well as the same visual assessment scale for pain 6, 24, 72, & 168 hours following treatment. The results of the study should show that following Gentlewave treatment patients will experience less severe post-operative pain, if any at all. The findings should support a treatment modality that retains tooth structure while completely removing necrotic debris and bacteria, as well as causing minimal to no post-operative pain.

| Gentlewave | Device | The Gentlewave system from Sonendo is a FDA cleared root canal irrigation device that uses broad spectrum acoustic energy, internally degassed distilled water, 3% NaOCl, and 8% EDTA to allow for a more thorough cleaning within the tooth. The fluids work to remove necrotic tissue, debris, biofilm, and bacteria while leaving dentin intact and preserving tooth structure. The Gentlewave irrigation replaces the NaOCl ultrasonic activation and EDTA steps of the standard endodontic protocol. Use of the Gentlewave system is contraindicated in teeth with immature apices, teeth with insufficient coronal structure, and teeth with root apices extending into the maxillary sinus. |

Patients will be asked to indicate their peak pain level in the twenty-four hours prior to the appointment using a visual analog scale (VAS). The VAS scale will consist of a 100mm line where 0 equals 'no pain' and 100 equals the 'worst pain imaginable'. Patients will be divided into one of two treatment groups, either standard cleaning protocol or Gentlewave irrigation. Patient demographics, anesthesia, cleaning and shaping instruments, irrigation technique, and obturation method and material will be recorded, along with the number of appointments, extent of treatment rendered, and the occurrence of over-instrumentation or overfill of obturation material. Once obturation is completed, patients will be given the same VAS scale to take home and asked to record their level of pain at 6, 24, 72, and 168 hours post-treatment.

| Primary | Level of Post-operative Pain (2020-2021) | To determine whether treatment with the Gentlewave system will significantly change the level of post-operative pain following endodontic treatment as measured by the VAS scale. Pain measurements were made using a 0-100 VAS- NRS. The '0' mark represented 'no pain' and the '100' mark represented 'the worst pain imaginable'. Scores 0-19 represented low pain, 20-39 was mild pain, 40-59 was moderate pain, 60-79 was high pain, and 80-100 was very high or severe pain. For this study, scores in the very high range were considered severe pain. | Posted | Mean | 95% Confidence Interval | score on VAS scale | 24 hours |

| EG001 | Gentlewave Treatment Group | Patients will be given a VAS scale to record their highest level of pain 6 hrs prior to treatment. The standard endodontic protocol will be followed through working length verification. For the Gentlewave treatment group, each canal will be shaped to a canal size of 20.06 and to 0.5 - 1mm short of the apical terminus. An occlusal platform will be prepared using the Kool-dam material recommended by Sonendo. The Gentlewave system will be held on the tooth by the clinician and will cycle through five minutes of 3% sodium hypochlorite, two minutes of 8% EDTA, and a final rinse of distilled water. Canals will be obturated with root canal sealer and gutta-percha. The same VAS scale from pretreatment to take home and asked to record their level of pain at 6, 24, 72, and 168 hours post-treatment. Gentlewave: The Gentlewave system from Sonendo is a FDA cleared root canal irrigation device that uses broad spectrum acoustic energy, internally degassed distilled water, 3% NaOCl, and 8% EDTA to allow for a more thorough cleaning within the tooth. The fluids work to remove necrotic tissue, debris, biofilm, and bacteria while leaving dentin intact and preserving tooth structure. The Gentlewave irrigation replaces the NaOCl ultrasonic activation and EDTA steps of the standard endodontic protocol. Use of the Gentlewave system is contraindicated in teeth with immature apices, teeth with insufficient coronal structure, and teeth with root apices extending into the maxillary sinus. | 0 | 38 | 0 | 38 | 0 | 38 |
