RESUMEN
Objective: This study sought to evaluate the effect of conventional syringe irrigation (CSI), irrigation with XP-endo Finisher file (XP-F), passive ultrasonic irrigation (PUI), and photon-induced photoacoustic-streaming (PIPS) methods on dentine debris removal from teeth with simulated internal root resorption (IRR) cavities by using scoring and image analyzing methods. Materials and methods: Chemomechanical preparation of 88 single-rooted sample teeth was completed, they were split longitudinally and IRR cavities were prepared. Simulated debris was placed into the cavities. Four teeth were separated to serve as the negative control group. According to the final irrigation technique, 4 experimental groups were created (n = 20): Group 1, CSI; Group 2, XP-F; Group 3, PUI; and Group 4, PIPS. The amount of remaining debris in the IRR cavities was examined under a stereomicroscope. Analysis was performed using two different methodologies: (1) scoring method and (2) image analyzing method. The data were statistically evaluated by one-way analysis of variance, Kruskal-Wallis, chi-square, and Dunn tests with a significance level set as 5%. Results: In both methodologies, PIPS was found to be significantly more effective than XP-F in terms of debris removal. There was no significant difference between XP-F and PUI (p > 0.05). According to the findings obtained from the image analyzing method, PIPS and PUI groups were not significantly different (p > 0.05). Conclusions: PIPS method can be selected as an irrigation activation methodology in teeth with IRR. Considering the similar results of both evaluation methods, image analyzing programs can be used as an alternative in studies on debris removal.

This case report describes the tissue injury caused by inadvertently extruded NaOCl through the apical constriction. A 56-year-old female patient with complaints of pain, swelling, and ecchymosis on the left side of her face was referred to our clinic. The symptoms had emerged following root canal treatment of the maxillary left first premolar, and a soft tissue complication due to apical extrusion of NaOCl was diagnosed. Antibiotics and analgesics were prescribed. DVT images revealed that the buccal root apex had perforated the maxillary bone. The patient was followed up every other day and became asymptomatic on the 10th day. Endodontic therapy was completed with routine procedures. Determining working length precisely and following irrigation protocols meticulously are indispensable to prevent this type of complication. 3D visualization of the affected area may reveal the cause of the incident.
RESUMEN
The purpose of this study was to gather information about Turkish general dental practitioners' treatment approaches towards endodontic emergencies, antibiotic-prescribing habits, and their participation in lifelong learning programs. Questionnaires were given to dentists who attended the 16th National Congress organized by the Turkish Dental Association. From 1,400 questionnaires distributed, 589 (43%) were deemed usable in this study. This survey dealt with questions that were subdivided into two main topics: dental emergency treatment approaches, and antibiotic prescription and information on lifelong learning program participation. The statistical analysis was conducted with a χ (2) test at a significance level of P<0.05. For irreversible pulpitis cases in vital teeth, most of the dental practitioners (65.3%) preferred single-visit root canal treatments. For teeth presenting a periapical lesion, the preferred treatment approach was root canal treatment (91.5%). The rate of prescription of analgesics and antibiotics was 21.7% in untreated acute apical periodontitis cases and 41% in acute apical abscess cases. Frequently prescribed antibiotics were amoxicillin-clavulanate (61.8%) and amoxicillin (46.5%). There was a tendency for practitioners to attend congresses as their years of professional practice increased (P<0.0001). There have been discrepancies between taught and observed practice. Educational initiatives are needed to prevent inappropriate prescription of antibiotics.
RESUMEN
INTRODUCTION: The purpose of this study was to evaluate the effect of acid etching on the compressive strength of 4 calcium silicate-based cements. METHODS: One gram of each corresponding powder of ProRoot MTA (Dentsply Tulsa Dental, Johnson City, TN), MTA Angelus (Angelus, Londrina, PR, Brazil), and CEM cement (BioniqueDent, Tehran, Iran) and a 0.33-g aliquot of liquid were placed in a plastic mixing capsule that was then mechanically mixed for 30 seconds at 4500 rpm in an amalgamator. For the preparation of Biodentine (Septodont, Saint Maur-des-Fossés, France), the liquid provided was added to the powder within the plastic capsule supplied by the manufacturer and then mechanically mixed for 30 seconds at 4500 rpm using the amalgamator. The resulting slurries were then placed incrementally into 40 cylindrical molds to give a total of 160 specimens that were incubated at 37°C for a week. Twenty specimens of each material were then subjected to the acid etch procedure. The compressive strength of the samples was then calculated in megapascals using a universal testing machine. The results were then subjected to 2-way analysis of variance analysis of variance followed by the Tukey post hoc test. RESULTS: The application of acid etch significantly reduced (P < .0001) the compressive strength of Angelus MTA and CEM cement; however, it did not reduce the compressive strength of ProRoot MTA or Biodentine. Regardless of the acid etch application, Biodentine showed significantly higher compressive strength values than the other materials (P < .0001), whereas CEM cement had the lowest compressive strength values. There was no significant difference between CEM cement and MTA Angelus. The compressive strength of ProRoot MTA was significantly lower (P < .0001) than Biodentine but significantly higher (P < .0001) than MTA Angelus and CEM cement in both the test and control groups. CONCLUSIONS: When the application of acid etchants is required, Biodentine and ProRoot MTA seem to be better options than MTA Angelus or CEM cement.
