Introduction: Root canal treatment (RCT) and its coronal restoration should be regularly assessed to ensure a successful treatment outcome. The aim of the current study is to evaluate the relationship between the obturation technical quality and coronal restoration in the clinical and radiographic outcome of RCT provided by Malaysian undergraduate students. Materials and Methods: A total of 143 root-treated teeth from 136 patients were evaluated through clinical examinations and periapical radiographs with a mean follow-up period of 2.4 (standard deviation = 1.59) years. The quality of the coronal restoration was classified according to modified United States Public Health Service criteria and the technical quality of the obturation was assessed based on two variables: length and density. Periapical status was evaluated according to periapical index scores. Results: About 64% of the teeth were classified as healthy with a significant reduction of apical periodontitis from 70.3% preoperatively to 36% at reassessment (P < 0.001). About 92.1% of obturation was of acceptable length, whereas 5% underfilled and 2.9% overfilled. Teeth with acceptable obturation length were five times less likely associated with apical periodontitis than the inadequately filled ones. 90% of canals had adequate obturation density with no significant association to apical periodontitis. Teeth restored with intracoronal restorations had 50% more chance of developing apical periodontitis. Inadequately restored teeth and teeth with poor obturation quality were associated with three times more likely apical periodontitis occurrence. The quality of endodontic treatment and the coronal restoration significantly influenced the periapical status (P < 0.001). Conclusion: The radiographic obturation quality and coronal restorations of the RCTs performed by the undergraduate students in a Malaysian public dental school were acceptable in 63.8% of cases with a 64% favorable outcome.

Introduction: The important aspect of endodontic treatment is root canal irrigation. Although agitation systems proved to have enhanced irrigant wall interactions, syringe needle-based delivery systems still play a significant role during the preparatory phases of root canal treatment. The current study aimed to evaluate the time taken for the irrigant delivery during conventional syringe irrigation using different volume syringes in different root canal preparations. Materials and Methods: Two hundred extracted single-rooted premolars with approximately round canals were randomly instrumented to preferred apical preparation sizes using 0.4 tapered Hyflex-CM rotary Ni-Ti instruments and randomly divided as follows: Group I, instrumentation to size 40, 0.04 taper (n = 50); Group II, instrumentation to size 30, 0.04 taper (n = 50); Group III, instrumentation to size 25, 0.04 taper (n = 50); and Group IV, instrumentation to size 20, 0.04 taper (n = 50). Fifty operators were chosen for the experimentation. They were asked to irrigate the prepared specimens using different volume syringes. The entire irrigant delivery time was recorded by a head nurse using a stopwatch, and the values were calibrated and statistically analyzed. Results: Group I recorded significantly lesser time for irrigant delivery during manual syringe needle irrigation (P = 0.005) compared to other groups. Conclusion: Irrigation delivery time was less in 40/0.04 taper preparations, using 1 ml volume syringes.

Introduction: The presence of postendodontic pain is an important issue, which can affect the patients' quality of life. Appropriate treatment selection, based on specific characteristics (e.g., clinical test results and patients' demographics), may reduce postendodontic pain. We aimed to evaluate the relationship of data mining algorithms in longitudinal data of postendodontic pain and treatment allocation to predict the best treatment option. Materials and Methods: The pain data of an original multicenter randomized clinical trial with two study arms, pulpotomy with mineral trioxide aggregate (PMTA) (n = 188) and root canal therapy (RCT) (n = 168), were used. The linear mixed-effects model and predictive algorithms were fitted in accordance with the personal characteristics of patients and diagnostic test results to determine the best treatment option. Using SPSS 23, SAS 9.1, and WEKA 3.6.9, the preferred treatment was identified via comparing the areas below the receiver operating characteristic curves and identifying the most appropriate algorithm. In addition, a decision tree was used to allocate the best type of treatment modality to reduce posttreatment pain. Results: For <18-year-old patients with irreversible pulpitis (IP) based on cold test and >18-year-old patients whose electrical pulp test (EPT) exhibited IP, the chosen treatment would be RCT (P < 0.05). However, for >18-year-old patients with IP based on cold test and <18-year-old patients whose EPT revealed IP, the recommended treatment would be PMTA (P < 0.05). Conclusions: The decision tree model seems to be able to predict the reduction of postendodontic pain in ~65% of patients if they receive optimal treatment.

Introduction: While conservative access preparations could increase fracture resistance of endodontically treated teeth, it may influence the shape of the prepared root canal. The aim of this study was to compare the prepared canal transportation and centering ability after continuous rotation or reciprocation instrumentation in teeth accessed through traditional or conservative endodontic cavities by using cone-beam computed tomography (CBCT). Materials and Methods: Forty extracted intact, matured, and 2-rooted human maxillary first premolars were selected for this study. Teeth were equally divided into two groups according to the access cavity design (traditional or conservative). Each group (n = 20) was further subdivided according to instrumentation technique (n = 10) into rotary 2 shape and reciprocation R-motion file subgroups. The teeth were scanned pre and post instrumentation using Planmeca ProMax to obtain two CBCT images for each sample. Images were analyzed and root canal transportation and centering ability were calculated for both buccal and palatal roots at three levels from their apices (3, 5 to 7 mm). Results: Although conservative access cavities showed more canal transportation and less centering ability than the traditional one, there was no statistically significant difference (P > 0.05) between them at all levels. Furthermore, no statistically significant difference has been identified in the same parameter between the two instrumentation techniques (continuous rotation and reciprocation) (P > 0.05). However, longer instrumentation time was measured in the conservative group compared to traditional. Conclusion: The size of endodontic access cavity has no effect on root canal transportation and centering ability when instrumentation was performed using 2 shape and R-motion file systems.

The enigma of successful treatment of mandibular second premolars with taurodontism has been explored for very long due to its rarity of occurrence. This case report aimed to enumerate the successful nonsurgical endodontic management of left mandibular second premolar #35 with three roots and taurodontism. A 34-year-old Saudi male patient with a noncontributory medical history was referred from the prosthodontic department for nonsurgical root canal treatment of tooth #35. Clinical examination revealed rotated clinical crown with caries related to tooth #35. Pulp sensibility cold test of the tooth showed no response, with the absence of pain on percussion and/or visible pocket depth. Radiographic examination showed long and deep pulp chamber and rotated and curved roots with broken apical lamina dura. The tooth was diagnosed with necrotic pulp and asymptomatic apical periodontitis. After making an access to the pulp chamber, two orifices were easily detected while the third one was found by the aid of surgical microscope. The canals were cleaned and shaped using ProTaper Gold file and then obturated with BioCeram Sealer and Gutta-Percha points, using hydraulic bonded obturation technique. Tooth immediately received the final crown. Clinical and radiographical examination after a 3-month follow-up revealed successful peri-apical healing with no symptoms. A literature search was organized to review the past publications about management of mandibular second premolar with taurodontism or anomalies in the root canal system. The search was focused on cases reported in Medline, Scopus, and Google Scholar databases. The conclusion of the seven selected studies and reported cases revealed that proper visualization with advanced microscopes or computer imaging radiographs, negotiation of the root canals, and efficient instrumentation and obturation enhance endodontic success.
