Quality Assessment of the Pulp Chamber Floor Refining by Different Ultrasound Devices

Access surgery is an important procedure performed during endodontic treatment as it allows the dental surgeon to access the pulp chamber and locate the root canals. During this procedure, spherical and conical stem diamond tips with inactive end are used to remove caries, establish a contour shape and refine the walls of the pulp chamber. Inserts coupled to dental ultrasound are constantly used to help refine the floor of the pulp chamber. However, depending on the vibration provided by the ultrasound device and incorrect handling of the insert, it will cause depressions and perforations in the floor of the pulp chamber. Given the context, this research aims to assess the quality of pulp chamber floor refinement by different ultrasound devices. This is a research with the principle of applied investigation, qualitative and quantitative approach, with an exploratory character, where 100 upper and lower human molars will be selected distributed in 4 groups, where the floor refinement will be carried out with TRA 24 ultrasound insert ( Trinks, São Paulo, Brazil) however, coupled to different ultrasonic devices: G1 (No. 25) CvDentus, G2 (No. 25) Sonic Plus Ecel, G3 (No. 25) Sonic Air Scaler and G4 (No. 25) Denshine . After completion of the access surgery, a visual inspection will be performed to assess the presence of excessive wear, depressions and identification of root canals. The results were tabulated, analyzed and it was found that there was no significant difference between the groups regarding the presence of excessive wear, depressions and identification of root canals. Thus, it is possible to conclude that all ultrasonic devices showed satisfactory results in the refinement of the floor of the analyzed teeth.
