If we need to negotiate the canal and prepare a glide path, the authors would recommend the following protocol as outlined in the following example. The site is secure. This will usually include larger diameter, relatively straight root canals. [12] reported that the greater taper of finishing files may be responsible for the transportation and straightening of severely curved canals. What is the difference between WaveOne Gold and ProTaper Gold? Dent Today. These findings were confirmed by Brklein and Schfer in 2012 when they compared Reciproc (VDW) and WaveOne (Dentsply Sirona) functioning in reciprocating motion to Mtwo (VDW) and ProTaper in conventional use (Brklein, Schfer, 2012). Apart from these benefits, preparation time was shown to be faster than when using the same instrument in full rotation (You, et al., 2010). English Although there have been studies showing the efficacy of WaveOne in initial treatment 5, 6, there has been little research in its use in retreatment. Coelho MS, Fontana CE, Kato AS, de Martin AS, da Silveira Bueno CE. After the establishment of an RMG, it is recommended to enlarge the glide path further to create a macro glide path. See clinical guidelines for the use of WaveOne Gold instruments. 2008;34(8):1003-1005. Wu H, Peng C, Bai Y, Hu X, Wang L, Li C, et al. The WaveOne Gold primary file (Dentsply Sirona) is 50% more resistant to cyclic fatigue, 80% more flexible, and 23% more efficient than the conventional WaveOne primary instrument (Ruddle, 2016; Webber, 2015). The efficacy of the systems was compared based on the amount and direction of canal transportation, centering ability, amount of material removed, and presence of canal aberrations. WaveOne Gold incorporates the metallurgical advancements of Gold wire and builds on the success of the original WaveOne reciprocating file technique taught in leading universities. When we select the primary file for canal preparation, it is generally a canal where a size 08 and 10 K-file has to be negotiated to working length, followed by preparation of a glide path or where a size 15 K-file fits loose in the canal to working length. (middle) Two Primary WaveOne Gold gutta-percha points fitted through the labial access cavity after root canal preparation. d. WaveOne Gold small file (20/07) (Figure 2). Hiran-Us S, Pimkhaokham S, Sawasdichai J, Ebihara A, Suda H. Shaping ability of ProTaper NEXT, ProTaper Universal and iRace files in simulated S-shaped canals. Single glide path file and single shaping file in most of the cases, 5. Any opinions expressed in the materials is those of the presenter and not the CE provider. Lim et al. Contact J Endod. Figure 15C shows the final result after root canal obturation and the access cavity closed with SDR posterior bulk fill flowable base (Dentsply Sirona) and capped with a final layer of ceram.x Sphere TEC one composite resin (Dentsply Sirona). [10,11,13,15,17], Previous studies have reported that both ProTaper rotary instruments (Dentsply Maillefer) and ProTaper hand instruments (Dentsply Maillefer) may result in canal transportation and straightening of the root canal. However, due to the differences in the mechanical characteristics of resin blocks and human teeth,[33] care should be taken when extrapolating the results of the present study to clinical cases. 2013;39(2):163-172. National Library of Medicine Brklein S, Poschmann T, Schfer E. Shaping ability of different nickel-titanium systems in simulated S-shaped canals with and without glide path. For more information, please visit www.TulsaDentalSpecialties.com or call 1-800-662-1202. In this clinical case, the tip of a size 25/02 nickel-titanium hand file fitted snug at working length in the buccal and palatal (Figure 18) canals, and matching WaveOne Gold primary gutta-percha points were placed and verified radiographically (Figure 19). Repeat the same procedure for the other canal and take an average of the measured length between the two canals. Peet van der Vyver and Martin Vorster show how WaveOne reciprocating instruments provide clinicians with safety, simplicity, and superior results. Figure 10: Periapical radiograph showing the position of the files during length determination two size 10 K-files in buccal and palatal root canal (left) and Figure 11: Clinical confirmation of reproducible glide path: a super loose 10 K-file must able to travel 4 mm-5 mm to and from working length without any obstruction (right). Current challenges and concepts in the preparation of root canal systems: A review. Single reciprocating file system WaveOne - A clinical review. Dhingra A, Kochar R, Banerjee S, Srivastava P. Comparative evaluation of the canal curvature modifications after instrumentation with one shape rotary and Wave One reciprocating files. The companys world-class live and online Continuing Education courses bring enhanced clinical success and confidence to tens of thousands of clinicians annually. Yared proposed a new technique employing reciprocating movements using just one instrument; biomechanical preparation with reciprocating motion has been claimed to lessen the likelihood of unforeseen file fractures. The patient, a 52-year-old female, presented with irreversible pulpitis on her maxillary right first premolar. WaveOne is developed for single use, removing the risk of cross-contamination and dramatically reducing the potential for dangerous file breakage. What are the file sizes of WaveOne Gold reciprocating files? Level 11 was traced at the midpoint between 10 and 12 [Figure 1]. Due to its optimized cross-section, tip diameter, and taper . No significant differences in the amount and direction of transportation and amount of material removed were observed between the groups at each level (P > 0.05). All three root canals were prepared with a WaveOne Gold primary 25/07 file after glide path preparation using stainless steel K-files and a ProGlider. Also, canals obturated with GuttaCore were retreated more efficiently and with fewer file separations than the canals obturated using continuous wave Moreover, Group B showed more canal aberrations than did Group A. Within the limitations of the present study, the creation of a glide path with the PathFile system improved the centering ability of the WaveOne reciprocating file in the apical and straight coronal portions of the simulated curved S-shaped root canals and reduced the incidence of canal aberrations. Finally, the images were evaluated at three zones: coronal straight zone (CZ) from level 13, first curvature zone from level 47, and apical curvature zone from level 8-12. To complete your endodontic experience, WaveOne Gold files can be combined with the following products for efficient cleaning and biocompatible seal: WaveOne Gold paper points are made to correspond with the four WaveOne Gold file sizes, helping to dry canals and remove excess sealer. a and b represent the two aspects of the simulated root canal. Bone Grafting / Tissue Regeneration Materials, One Shape for Endodontic Instrumentation, Long-Term Efficacy of a Methacrylate Resin-Based Root Canal Sealer. This product is not eligible Torsion and fatigue through flexure are the two main reasons for this failure (Serene, Adams, Saxena, 1995). Correctly answering the questions will demonstrate the reader can: In this CE, Drs. Gauging the apical foramen with a corresponding nickel-titanium hand file is another alternative (Ruddle, 2016). A WaveOne file was used in a reciprocating motion according to the manufacturer's instructions using (WaveOneTM endo motor). Gagliardi J, Versiani MA, de Sousa-Neto MD, Plazas-Garzon A, Basrani B. Recently, WaveOne Gold, a new generation of reciprocating files, was launched. Group B showed more canal aberrations than Group A, and the incidence of these aberrations was associated with the groups [Table 3]. This will usually include larger diameter, relatively straight root canals. Any canal where a size 20 or 25 K-file fits loose in the canal and is not necessary to negotiate and prepare a glide path with smaller instruments. A preoperative periapical radiograph revealed that the tooth was treated previously with an emergency root canal treatment (Figure 26A). The WaveOne Gold Glider operates in a reciprocating motion with an ISO size 15 tip and 2% taper manufactured from gold wire. 2023 Newcom Media Inc. All Rights Reserved. There were no statistically significant differences in the amount of material removed between the groups at each level (P > 0.05). Forty standard clear resin Endo Training Bloc-S blocks (Dentsply Maillefer) with ISO #15, 0.02 taper canals were used in this study. . The new WaveOne NiTi primary reciprocating file, if used after a previous glide path, produced less modification in canal curvature compared with the WaveOne alone, as actually suggested by the clinical procedure flowchart (17). J Endod. Our Free CE is limited to only 2 free credit hours per year. This movement is followed by a 30-degree clockwise (CW) movement, which ensures that the instrument disengages before excessive torsional stress is transferred onto the metal alloy and before the instrument can bind (taper lock) into the root canal. Phone: 800-662-1202 The irrigation needle curves and flex easily providing an efficient cleaning and disinfection until the apex, Activated fluids promote deep cleaning and disinfection facilitating 3-D obturation and long-term success. WaveOne will allow practitioners to save time and increase patient safety while providing premium-quality root canal treatment. Pre- and postoperative images were superimposed and evaluated at 12 defined measuring points. The patient, a 51-year-old female, presented with a nonvital maxillary left first molar restored with a porcelain-veneered crown. J Endod. In addition, seven more equidistant levels were traced between levels 3 and 12 and numbered as 4, 5, 6, 7, 8, 9, and 10. Questions are addressed at the end of the presentation for at least ten minutes. WaveOne Reciprocating Files (DENTSPLY Tulsa Dental Specialties) sizes are Small, Primary, and Large and available in 21-mm, 25-mm, and 31-mm lengths. 2000;26(3):156-160. Ding-Ming H, Hong-Xia L, Cheung GS, Lan Z, Hong T, Xue-Dong Z. The file features M-Wire nickel-titanium (NiTi) construction for increased flexibility and greater resistance to cyclic fatigue compared to conventional NiTi), the leading cause of file separation.1. The objective of recapitulation is to loosen up any compacted debris and move it back into solution before it is flushed out of the canal. Registrants will have to either sign in (previous webinar attendee) or sign up (first-time webinar attendee) for our CE quiz system on our publications website. WaveOne Gold primary file (red ring) (Figure 3) tip of the file is size ISO 25, and the first 3 mm of the file (D1- D3) has a continuous taper of 7%. The efficacy of the systems was compared based on the following factors: the amount and direction of canal transportation, centering ability, amount of material removed, and presence of canal aberrations (apical zip, ledge, danger zone, and narrowing) [Figure 2]. Gu Y, Kum KY, Perinpanayagam H, Kim C, Kum DJ, Lim SM, et al. WaveOne instruments: clinical application guidelines. However, in canals with severe apical curvatures, very long root canals or in canals where the glide path preparation was very challenging, the WaveOne Gold small file can be used to start root canal preparation with more safety. This is achieved by dispensing an irrigation solution (NaOCl) into the root canal (Figure 16A), followed by inserting a 08 or 10 K-file, using a watch-wind motion (recapitulation) in the canal (Figure 16B), followed by a final irrigation step (irrigation-recapitulation-re-irrigation, IRR) (Figure 16C). During instrumentation, copious irrigation with water was performed after each file, and all preparations were performed by one operator experienced in the use of rotary instruments. WaveOne Gold (WOG) G-wire technology is available in 4 sizes: small (#20, 0.07), primary (#25, 0.07), medium (#35, 0.06), and . * OneFile G features unique shape memory NiTi alloy. Also new is the parallelogram-shaped cross section, which helps improve cutting efficiency and debris removal within the canal. The aim was to compare the shaping ability of WaveOne reciprocating files with or without glide path in simulated curved S-shaped root canals. From DENTSPLY Tulsa Dental Specialties, the WaveOne Reciprocating File provides a breakthrough approach to endodontics with a single-file shaping technique. 1997;23(2):77-85. Inclusion in an NLM database does not imply endorsement of, or agreement with, Seventy-five S-shaped canals in resin blocks were randomly allocated to 3 groups (n = 25): WaveOne (group 1), full sequence of ProTaper Universal files in conventional movements (group 2), and full sequence of ProTaper Universal files in reciprocating movements (group 3).Preoperative and postoperative photographs of the simulated canals were taken under standardized conditions, after . Franais Any canal where a size 30 or 35 K-file fits loose in the canal and is not necessary to negotiate and prepare a glide path with smaller instruments. Sattapan B, Nervo GJ, Palamara JE, Messer HH. Move the rubber stop to a working length of 4 mm-6 mm (depending on your level of expertise) longer than the initial recorded length (Figure 13 middle). To confirm that a reproducible glide path is present, a size 10 K-file is taken to full working length. Most teeth will require a primary WaveOne file, but initial resistance with a 10 K-file will help determine the preferred WaveOne instrument. 8600 Rockville Pike WaveOne NiTi files appear to maintain the original canal anatomy, and the presence of a glide path of the canal . All files now have a reduced taper to support the clinician to achieve minimally invasive . J Endod. The patient, a 40-year-old female presented with a nonvital right maxillary first premolar with decay under a previously placed composite restoration (Figure 8). This file can also be used after the primary file if more shape is desired, or if it is felt that not enough infected dentin was removed from the canal. The simulated curved S-shaped canals were dyed using ink, preinstrumentation images were scanned, and resin blocks were prepared and divided into Group A: PathFile and WaveOne and Group B: WaveOne. In this article, the authors will discuss the design features of the instruments and focus on the WaveOne Gold primary file. Realize some characteristics of M-Wire technology. WaveOne files are available exclusively in pre-sterilized blister packs and fitted with a nonautoclavable handle. Clinicians can feel confident knowing that the single-use WaveOne option eliminates the risk of cross-contamination. Twenty Protaper Next files (X2) and 20 WaveOne Gold Primary files were included in this study. Figure 25: (left) A preoperative periapical radiograph. Brklein S, Schfer E. Apically extruded debris with reciprocating single-file and full-sequence rotary instrumentation systems. Endodontic Practice US is a leading dental journal and your publication for endodontic continuing education, endodontic case studies, and more. A CBCT scan confirmed that there were two separate roots. J Endod. All canals were postoperatively scanned and saved as JPEG files. The objective with the first cutting cycle will be only to cut with the instrument until the rubber stop reaches the cusp reference point (Figure 13 right), thereby ensuring that the operator knows that it is time to remove the instrument and clean the cutting debris from the flutes (Figure 14). The result? WaveOne Gold medium file (green ring) (Figure 4) tip of the file is ISO 35, and the first 3 mm of the file (D1-D3) has a continuous taper of 6%. Their results support the findings in this study which showed significantly higher values for centering ability with glide path preparation. 2012;45(5):449-461. Within the limitations of the present study, the creation of a glide path using the PathFile system improved the centering ability of the WaveOne reciprocating file in the apical and straight coronal portions of simulated curved S-shaped root canals and also reduced the incidence of canal aberrations. (right) Postoperative result after root canal preparation, irrigation, Figure 23: (left) Preoperative periapical radiograph. St. Louis, MO: Ishiyaku EuroAmerica; 1995.
