Objectives: The management of endodontically treated teeth with apical periodontitis is debated among clinicians. The aim of this study was to evaluate treatment choices for endodontically treated teeth with different sizes of periapical lesions among endodontists, endodontics postgraduate students, general dental practitioners, and undergraduate students who had fulfilled their theoretical and clinical training in endodontics. Materials and methods: Periapical lesion images (no periapical lesion and 1-mm, 3-mm, and 5-mm periapical lesions) were formed on 4 different radiographs with a software program, and the survey included 16 radiographs that were emailed to 1881 participants. Treatment options included extraction, surgical or nonsurgical retreatment, and wait and see. The χ2 test was used to compare the responses of the participants. Results: The survey was returned by 1039 participants (55.23%). There were statistically significant differences among the responses of all participants for all cases (P < .05), except a case with a broken file and no lesion (P = .918). All participants decided to extract at an increased size from a 1-mm periapical lesion to a 5-mm periapical lesion. At all lesion sizes, general dental practitioners planned retreatment less when compared with other groups. Conclusions: This survey study showed that there was a positive correlation between endodontic education level and retreatment decision-making. Dentists who confront seemingly hopeless endodontically treated teeth such as an instrument fracture, a missing canal, or a large periapical lesion should consult with an endodontist before making the decision to extract the tooth.

This study aimed to evaluate the effect of ultrasonic activation on coronal marginal adaptation and microporosity of tricalcium silicate-based materials. Sixty freshly extracted human maxillary lateral incisor teeth were instrumented with ProTaper Next X2 files followed by Peeso-Reamer burs, sizes 1 to 5. The specimens were randomly divided into six groups (n = 10): Group 1, Biodentine + hand condensation; Group 2, Biodentine + ultrasonic activation; Group 3, NeoMTA Plus + hand condensation; Group 4, NeoMTA Plus + ultrasonic activation; Group 5, ProRoot WMTA + hand condensation; and Group 6, ProRoot WMTA + ultrasonic activation. All tested materials were mixed mechanically and placed 2 mm underneath the cement-enamel junction by hand condensation or indirect ultrasonic activation. Volumetric analysis of the voids between the dentine wall and coronal barrier material and the porosity within the material was evaluated with micro-CT. There was no significant difference in marginal adaptation among the six groups (P > 0.05). Ultrasonic activation favoured a reduced microporosity in Biodentine Group (P < 0.001).

Aims and background: It was aimed to evaluate compressive strength (CS), surface roughness, and microhardness of mineral trioxide aggregate (ProRoot MTA) and Biodentine (BD) after adhesive application. Materials and methods: Tests was carried out according to international ISO standard. ProRoot MTA and BD were prepared in Teflon molds according to manufacturer's instructions: n = 210 for CS; n = 210 for microhardness. Samples were incubated for 7 days at 37°C in 100% humidity. Surfaces were smoothed with up to 2000 grits of silicon-carbide sandpaper on abrasive device at 150 rpm, randomly divided into seven groups (n = 15). Clearfil Universal Bond, All Bond Universal, and Single Bond Universal (SBU) were applied in both total-etch and self-etch (SE) modes. Adhesives were applied according to manufacturers' recommendations (no adhesive used in control). CS was performed at speed of 1 mm/min, microhardness at 100 gr for 15 s. The surface roughness of the samples was analyzed with atomic force microscopy. Two-way analysis of variance and post hoc Tukey tests were used for the evaluation of the data. Results: Man CS and microhardness values between ProRoot MTA and BD were as follows: 24.9 N, 72.6 HV; 59.8 N, 59.0 HV, respectively. In CS, BD was higher than ProRoot MTA (P < 0.05). In other comparisons except for SBU SE group (P < 0.05), BD and ProRoot MTA showed similar results (P > 0.05). However, ProRoot MTA was found higher than BD regarding microhardness (P < 0.05). As a result of the adhesive application in both BD and ProRoot MTA groups, a decrease in surface roughness was observed compared to the control group. Conclusion: BD exhibited better results than ProRoot MTA regarding CS. However, ProRoot MTA was found to be more successful than BD in terms of microhardness. BD and ProRoot MTA showed similar physical properties in terms of surface roughness. To improve regenerative procedures, besides the selection of bioceramic cements, the interaction between cements and materials applied during coronal restoration should be considered.

Comparison of the effectiveness of single-visit and multi-visit root canal treatment onhealing intra-oral sinus tractFatma Begüm Peker, Mehmet Burak GüneşerDepartment of Endodontics, School of Dentistry, Bezmialem Vakif UniversityObjective: To evaluate postoperative pain and intra-oral sinus tract healing in teeth with chronic apical periodontitistreated in a single visit and to compare the results with multi-visit root canal treatment using an intracanal calciumhydroxide.Materials-Methods: A total of 60 patients in need of non-surgical endodontic treatment participated in this study. Allpatients provided informed consent. The age range of the patients was between 18 and 65 years. The selectedteeth all had a single root and single canal, along with radiographic evidence of apical periodontitis and intra-oralsinus tracts. The patients were randomly divided into two study groups: Group 1(single-visit) and Group 2(multi-visit). Local anesthesia (Ultracaine DSForte;Aventis Pharma,Istanbul,Turkey) was administered and the tooth wasisolated with a rubber dam. Access cavities were created using sterile diamond burs. The working length of eachtooth was determined using an electronic apex locator (Propex Pixi,DentsplySirona,Ballagues,Switzerland) and asize #15 K-type stainless steel file was inserted into the root canal, confirmed radiographically. To shape the rootcanals, nickel–titanium rotary files (VDW GmbH,Munich,Germany) were used in accordance with the manufacturer’sinstructions. Rotary files with a #40 size and variable taper tips of up to 0.04 were used. In the multi-visit group,after the shaping process, calcium hydroxide was placed. All multi-visit treatments were completed one week afterthe initial visit. For all groups, the final irrigation process consisted of the following steps: 5 mL of 2.5% sodiumhypochlorite (Wizard,Ankara,Turkey), 5 mL of 17% ethylenediaminetetraacetic acid (Werax,Izmir,Turkey) and 5 mLof saline. In the single-visit group, after the final irrigation, the root canals were filled with gutta-percha and epoxyresin-based root canal sealers (Ah Plus,DentsplySirona) using the cold lateral compaction method during the samesession. For the multi-visit group, after the removal of calcium hydroxide and following the final irrigation protocol,the root canals were filled during the second appointment. Radiographic checks were performed to ensure properroot canal fillings. Coronal restorations of the teeth were carried out with resin composite material (Z250,3M ESPE).Postoperative pain was scored for the 2 days following the treatment using a visual analogue scale. In the multi-visit group, pain was also assessed at the beginning of the second appointment and patients were asked about thepresence or absence of pain between visits. All patients were scheduled for follow-up appointments and weremonitored until the day of the sinus tracts were healed (Healing means the closing of the sinus tract). Data wereanalyzed using the two sample proportion test and Pearson chi-square tests (α=0.05).Results: There were no significant differences between two groups regarding the incidence of postoperative pain(p>0.05). In the multi-visit group, greater healing was observed on the 3rd and 7th days as compared to the 14thday(p<0.05). However, the day of healing showed a homogeneous distribution in the single-visit group, and therewere no statistically significant differences between the 3rd, 7th, and 14th days(p>0.05).Conclusion: Both groups experienced similar postoperative pain. But it has been observed that a multi-visit protocolprovides earlier healing than a single-visit.Keywords: sinus tract, apical periodontitis, single-visit, multi-visit, postoperative pain
