Introduction: Root canal preparation is an important step in root canal treatment. The use of stainless steel K-Files is time-consuming and causes fatigue to patients and operators. The large taper endodontic hand instrument can be used as an option for another preparation instrument. The purpose of this article is to determine the advantages of using large taper endodontic hand instruments as a preparation instrument compared to conventional stainless steel K-Files. Case: The 24-year-old male patient presented with pain in his lower left tooth even though it was not used. Examination of teeth 35, percussion and press (+), palpation (-), CE (-), exploration of root canals with smooth broach (+). There was a radiolucent image in the distal crown that had reached the pulp chamber, radiolucency with a blurred border of 2 mm in diameter at the periapical area, and the dilation of the periodontal ligaments along with the roots. Tooth 35 diagnosis was partial pulp necrosis with periapical lesions. Case Management: Root canal treatment of teeth 35 using hand-used ProTaper with the crown down technique up to F4 WL = 21 mm. Obturation with single cone technique with Endomethasone as a sealer. Discussion: The large taper instrument is very flexible and easily enters narrow and bent root canals, thus it can shorten the working time, reduce the risk of fatigue for patients and operators, improves the cleaning of the root canal system, and consistent root canal formation. The crown down technique used can reduce the risk of preparation errors, prevent debris extrusion and improve obturation quality. Conclusion: Root canal preparation using a large taper endodontic hand instrument can shorten the working time and reduce the risk of fatigue for patients and operators compared to preparations using conventional stainless steel K-File.

Root Canal System

The objectives of root canal treatment are to prevent the apical parodontitis, to heal the acute or cronic apical periodontits and to maintain the results, keeping the teeth on the arch in a functional stage. Thus, accuratelly elimination of soft and hard tissues (cleaning and shaping of the root canal system), disinfection and complete, homogeneous and tridimensional filling of the root canal system are very important to successful endodontic treatment. Modern concepts in endodontic treatment rely on technological progress and therefore many cases are successfully fulfilled, but the practitioner may be put in front of procedural erorrs both during and after endodontic treatment. Apical blockage, ledging, zipping, stripping, perforations in the floor of the pulp canal chamber or root canals perforations are the most common errors, but in many clinical situations they can be prevented and even surpassed once happened.

Chamber Floor

In root canal treatment, the foundation on which all surgical procedures are performed is a thorough knowledge of the anatomy of the pulp chamber and the root canal system. The endodontic triad comprises biomechanical preparation, microbial control and complete obturation of the root canal space. Knowledge of the pulp chamber floor anatomy is important in locating the numbers and orifices of root canals present within the tooth being root canal treated. This is particularly important while treating teeth that are heavily restored, mal-positioned, or calcified. The current review attempts to explain the complex anatomy of the pulp chamber floor and its significance in root canal treatment. CPD/Clinical Relevance: To allow the location of all root canal orifices in the pulp chamber and to perform successful root canal treatment, knowledge of pulp chamber floor anatomy is essential. The clinician should consider that, as the external morphology of the tooth varies in individuals, so does the internal morphology.

Background and aims. The purpose of this study was to compare several parameters of root canal preparation using two different rotary Nickel-Titanium instruments: Pro-Taper (Dentsply Maillefer, Ballagigues, Switzerland) and Hero-Shaper (Micro Mega, Besancon, France).Methods. Twelve extracted maxillary premolars were randomly divided into two groups and embedded into a muffle system. All root canals were prepared to size 25 using Pro-Taper or Hero-Shaper rotary instruments.  The following parameters were evaluated: root canal form, centering capacity of the instrument, the presence of residual dentinal debris and smear layer on the root canal walls, working time and the occurrence of intraoperative accidents. Statistical analysis was performed using the chi2 test (p=0.05).Results. The majority of the root canals prepared with Hero Shaper (88.89%) and ProTaper (77.78%) showed a round or oval cross-section postoperatively. Superposition of pre- and postoperative photographs of the cross-sections showed that for the coronal third of the root canals the Hero Shaper performed in a superior manner, while for the apical third better results were obtained with the Pro Taper system. Cleanliness of the root canal walls was investigated under the SEM, in the middle third of the canal, using a five-score system for debris and smear layer. For debris Hero Shaper and Pro Taper rotary systems achieved 66.67% and 50% scores of 1 or 2, respectively. The results for the smear layer were similar: cleaner root canal walls were found after preparation with Hero Shaper (66.67% scores 1, 2), followed by Pro Taper (50%). Mean working time was shorter for Hero Shaper (124s) than for Pro Taper (184s); the difference was not significant.Conclusions. Within the limits of this study, both systems had almost the same cleaning ability and excellent centering capacity.

Root Canal System

Successful outcome of endodontic treatment depends on the identification of all root canals which in turn guarantee complete extirpation of pulp tissue, proper chemo-mechanical cleaning and shaping and three dimensional obturation of the root canal system with an inert filling material. However endodontic treatment can fail for many reasons, such as diagnostic errors, persistence of the infection in the root canal system, errors in debridement and shaping of the root canal systems, instrument fractures, poor restorations and extra roots or canals if not detected are the reasons for failure. Undetected extra roots or root canals have been considered as a major reason for failure of root canal treatment. Many of the challenges faced during root canal treatment may be directly attributed to an inadequate understanding of the canal morphology of teeth. A broad knowledge of both the external and internal anatomy of teeth is of great importance for adequate endodontic treatment. We present a case report of 2 roots in mandibular lateral incisor.

AbstractIn case of failed root canal treatment endodontic retreatment of the root canal system is necessary. The aim of the present study was to compare the gutta-percha removal with Protaper retreatment files (Dentsply Maillefer, Ballaigues, Switzerland), K3 (SybronEndo) and Hero Shapers (MicroMega, Besancon, France). Method: Thirty freshly extracted human single rooted teeth were prepared with ProTaper rotary instruments up to file F3 andfilled with 30 # GP cones and AH plus sealer. The teeth were then stored for 1 week. The teeth were divide into 3 retreatment groups (n=10). The gutta-percha was removed using Protaper retreatment files, K3 and Hero Shapers. Teeth were then evaluated using radiographs. Results: Comparing the ratio between clean canals Protaper and K3 showed better debris removal as compared to Hero shaper. But no significance difference was found.

SummaryBackground/Aim: The aim of root canal treatment is the thorough cleaning, shaping and obturation of the root canals. Variations in root canal anatomy increase the difficulty of the root canal treatment and therefore the possibility of failure. The mandibular premolars often present complex anatomy and the existence of mandibular second premolars with three root canals is very scarce. This report presents the successful endodontic management of four mandibular second premolars with three root canals.Cases Report: In all cases working length was estimated using the working length radiograph and an apex locator. Canal orifices were enlarged with Gates-Glidden drills and manual instrumentation performed with Stainless Steel reamers and Hedstroem files, using either step-back or crown-down technique. Sodium hypochlorite (NaOCl) 2.5% was used as an irrigant. Root canal obturation were then performed using the cold lateral condensation technique with gutta-percha points and Roth’s 801 canal sealer. The cases were scheduled for clinical and radiographic follow-up examination. Clinically in all follow-up examinations the teeth were asymptomatic. For the three cases with periapical lesions, post treatment radiographs, demonstrated periapical healing. Additionally, in the case without periapical lesion, the 9 months recall radiograph revealed healthy periapical conditions.Conclusions: Mandibular premolars should never be underestimated and the clinician should always be alerted for anatomic variations.

Introduction: Irrigation of the root canal is an important part of the endodontic treatment. Root irrigation technique can be done with the manual and sonic system by using 2.5% NaOCI solution. Calcium hydroxide [Ca(OH)2 ] is used as a medicament for root canal sterilization. Root canal treatment will fail due to the imperfect removal of Ca(OH)2 residue. The objective of this research was to analyze the comparison of the removal of Ca(OH)2 medicaments on the root canal treatment irrigated with manual and sonic agitation technique using 2.5% NaOCI. Methods: The methods used in this study was experimental laboratory. The sample used was 30 maxillary incisors. The teeth were then divided into two groups randomly, then the root canal preparation was done by the crown down technique with irrigation using 2.5% NaOCI. The radicular part of the teeth was then split longitudinally, given a standardized groove in the one-third of the apical part, then applied with water-solved calcium hydroxide. The teeth were unified afterwards by using flowable composites, then soaked in the artificial saliva. The sample of the 1st group was irrigated by manual agitation technique, and the 2nd group by sonic agitation technique. The data results were analyzed by Kruskal-Wallis and Mann-Whitney tests. Results: The results of Ca(OH)2 removal were different between manual agitation technique compared to the sonic agitation technique. Conclusion: The irrigation using 2.5% NaOCl with the sonic agitation technique were proven to be more effective in removing Ca(OH)2 from root canals than the manual agitation technique.
