    Treatment of maxillary central incisors with internal resorption: Two case reports

    Internal root resorption is a rare condition, but it may require complex treatment protocols, depending on the progression. The aim of this case report is to present the treatment protocol and the follow-up results for 2 cases of a right upper central incisor with internal root resorption. A 15-year-old female patient presented with the chief complaint of dental caries. The radiological examination revealed that tooth #21 had internal resorption (IR) in the middle third of the root. The warm vertical condensation technique was applied using a warm obturation system. At 3 years, the tooth was asymptomatic and no lesions were observed. A 48-year-old female patient was referred to the clinic for a routine control. The radiological examination revealed IR in the middle third of tooth #21. As the resorption area was quite wide, cone beam computed tomography was used. The results indicated that there was also external resorption in the buccal part of the root. Therefore, the treatment protocol was changed and the IR area was sealed with mineral trioxide aggregate. At 1 year, the tooth was asymptomatic and no lesions were observed. Keywords: Cone beam computed tomography; internal root resorption; mineral trioxide aggregate; root perforation; trauma.

    Effect of different obturation techniques on sealer penetration into dentinal tubules after final irrigation with xp-endo finisher file

    The first objective of this research was to evaluate the effectiveness of XP-Endo Finisher on dentinal tubule penetration of irrigation solution using confocal laser scanning microscopy. The main purpose of this research was to compare the effect of cold lateral condensation, continuous wave obturation and core-carrier based techniques on sealer penetration. Sixty mandibular premolars were prepared and allocated into two experimental groups (n=30) as the final irrigation technique and obturation technique experiment. In the final irrigation technique experiment, final irrigation was performed with XP-Endo Finisher, passive ultrasonic irrigation (PUI) and conventional needle irrigation (CNI) (n=10). The roots in the obturation technique experiment were also assigned into 3 groups and obturated with cold lateral condensation, continuous-wave obturation and core-carrier techniques (n=10). The most effective activation method, which emerged as a result of the first part of this study, was used as the final irrigation method in the obturation technique experiment. Then, all roots were sectioned in 1-mm-thick slices at 3mm from the apex for scanning. In terms of depth and percentage of material penetration, CNI exhibited significantly the lowest values and no significant difference was found between others. Also, there was no significant difference among obturation methods. In conclusion, XP-Endo Finisher and PUI are more effective than CNI on irrigant penetration. Sealer penetration into dentinal tubules is independent of obturation techniques.

    Aim:The objective of this study was to measure in a laboratorysetting the pH of tooth coloured ProRoot MTA and MTAAngelus following various mixing and placement techniques,including mechanical mixing, manual mixing and indirect ultrasonicactivation.Materials and Method: Tooth coloured ProRoot MTA andWhite MTA Angelus were used. One gram of each powderwas mixed with a 0.34 g of distilled water that were allocatedto eight experimental groups, each containing three specimens.Four groups were prepared by mechanical mixing ofcapsules for 30 s at 4500 rpm the other four were mixed manually.Half of the specimens in each group were placed inmoulds using indirect ultrasonic activation. pH values wererecorded directly from within the freshly mixed material andwere analyzed using one-way ANOVA at a 0.05 level of significance.Results: No significant difference in pH was found betweenthe mixing and placement techniques or the materials tested.The highest pH value recorded was in the ProRoot group thatwas mixed manually and placed ultrasonically (11.64). TheAngelus group, which was mixed manually without an ultrasonicagitation, had the lowest pH values (10.42).Conclusion: Mechanical mixing and ultrasonication conferredno significant disadvantage in terms of the initial pH ofthe material. Since mechanical agitation of encapsulated cementsprovides more consistent mixes, it might be possible touse this technique combined with ultrasonic agitation as analternative to manual mixing, both in clinical and in laboratoryconditions, in order to achieve standardization of the materialso as to enhance its properties.
