Root Canal Treatment Using Protaper Dentsply System. Simple Step Wise Guide. , The ProTaper Dentsply system is the alternative to all other file systems in which each file has a fixed taper. Each ProTaper file has a variable changing taper over the length of its cutting blades. Specifically, the ProTaper shaping files have small-sized tips, which act as guides to follow the path of the canal previously secured with hand files. Progressively tapered shaping files work away from their apical extents and, importantly, selectively cut dentin toward their larger, stronger and more active blades Hand Protaper Files The ProtocolStep 1- Cut an access cavity using the Endo access kit ( Dentsply-Maillefer)/ Or You can do it on your way.Step 2- Refine the canal orifices with the X-Gates at 700rpm to get a straight line access Place the X-gates along the natural axis of the orifice without working the instrument. Then, starting rotation, use a circular motion without pressure to create a funnel at this level. This should be followed by a brushing outstroke motion away from the furcation until the head of the X-Gates gets passively inside the canal orifice.Step 3- Fill the pulp chamber with a lubricant Step 4- Scout the coronal two-thirds 1-Select an ISO ? 10 K file precurved, and scout the canal to light resistance. Then, use a watch-winding-pull motion to create space at this level. 2-Repeat the same procedure with the ? 15 K file and the ?20 K file. 3-Transfer the length of the ?15 K file to S1. Rotary Protaper Files Step 5- Shape the coronal two-thirds ( 300rpm ) with NaOCl irrigation At this stage, the apical three or four millimeters of S1 should be loose inside the root canal. 1-Start working S1 with a firm brushing outstroke action away from the furcation.to progressively reach the level of the 15 K file. Use a slow motion with a 4mm amplitude. Visually check the location of the debris on the flutes. No debris should be observed on the apical aspect of S1 2-As described for S1, work S2 slightly shorter than S1.Step 6- Scout the apical one-third 1-A?10K file, precurved, is used with a lubricant to negociate the apical third of the root canal and reach the apical limit. 2-Determine the working length with an apex locator or an X-ray. Smooth the path of the canal using an up-and-down motion with a short amplitude (2mm) until the file is loose. 3- Do the same with the ?15K file to get a long (4 to 5mm) and reproducible glide path.Step 7- Shape the apical one-third 1- Switch to NaOCl and work S1 with the same brushing action to the working length, but stop brushing I mm shorter and let the file passively reach the apical limit. 2-By hand, drop the rotary S2 to resistance in order to assess the distance of work to be done with that file. After an adequate work by S1, S2 should never have more than 2mm of work to accomplish. 3-Then use the engine-driven S2 as described for S1. Due to the brushing outstroke motion, the operator should feel that the previous resistance met in step 2, has been completely relieved 4- Disconnect the handpiece from S2 and confirm precisely the working length with an apex locator connected on S2Step 8- Finish and blend the apical one-third with the coronal two -thirds 1- By hand, drop the rotary F1 to resistance in order to assess the distance of work to be done with that file. After an adequate work by S1 and S2, F1 should never have more than 2mm of work to accomplish. Then, the engine-driven F1 is passively allowed to progress apically, in one or more passes, to reach the canal terminus. F1 must be used in a non -brushing manner with no vertical pressure. The author preference for this stage is to use a manual F1 with an apex locator connected on it, to precisely achieve the apical shape. For manual ProTapers, the recommended motion is : half a turn clockwise- three quarter turns anti-clockwise while withdrawing the file 2- Following F1, a ? 0.2/20 K file is dropped inside the canal to gauge the apical diameter. If the file is snug at the working length, the apical size is 20 . In this case, F2 and F3 must systematically be used in a step-back fashion to increase the deep shape. F2 is placed ½ mm shorter than F1 and F3 one mm shorter than F2. The finishing files F2 and F3 should never have more than 2mm of work to do. 3- If the 0.2/20 K file moves beyond the foramen, gauge again with the ? 0.2/25 K file. If the file is snug at the working length, the apical size is 25. Use F2, shy from the working length, as described for F1. Then use F3 one millimeter shorter than F2. 4- The same gauging procedure with ISO K files is repeated for larger apical sizes. 5- Root canal obturation will be discussed in separate post. After BMP is completed you can use protaper Gattapurcha (6%) for obturating the canal. mostly single cone obturation is enough. Root Canal Treatment By Protaper system Note : Between each active file, the root canal system is irrigated with 2ml of NaOCl, apical patency is confirmed and the canal re-irrigated. , http://bit.ly/YgXvWX
