Endodontics has significantly evolved in recent years. Technologies that facilitate endodontic therapy based on serious research have made our specialty reach extremely high levels of success. Therefore, today all procedures proposed in the specialty are based on scientific evidence.

Gingival cyst of the adult is not always noticed due to its limited growth and absence of symptomatology. In nearly all cases, it is located on the buccal surface. Differential diagnosis includes mucoceles, gingival abscesses, fistulas, and some benign neoplasms. Adenomas, neuromas and neoplasms or peripheral odontogenic cysts can be located in the gingival tissue, and when they are small and still detectable, they can simulate the gingival cyst of the adult. The latter is a round,...

Introduction: Endodontic treatment allows for decontamination of the root canal system by means of chemomechanical preparation, intracanal dressing and filling. However, the literature shows that microorganisms may have developed ways of resisting the procedures of traditional method. Photodynamic therapy (PDT) has been incorporated in conventional endodontic treatment as an additional therapeutic measure for microbial control, besides being of easy and rapid application in single or...

Introduction: Understanding of pulp cavity variations is necessary to guarantee success of endodontic treatment, which makes relevant the recognition of accessory canals in furcation areas (FC). Objective: The aim of this study was to report a clinical case of a mandibular first molar associated with extensive bone loss in furcation area with the presence of an accessory canal. Case report: Patient’s complaint was the appearance of “bubbles surrounding the tooth.” Clinic examination...

The greatest challenge to successful endodontic treatment is the elimination of microbiota. Mechanical instrumentation as well as auxiliary chemical substances are used to eliminate this microbiota. In addition to irrigating solutions, other complementary techniques such as passive ultrasonic irrigation (PUI) and laser are used to optimize elimination of microorganisms. Thus, the present study aimed at a bibliographic survey of different types of agitation of irrigating solutions in...

Introduction: Root resorption is a pathological process that results in loss of cementum, dentin and bone. It is triggered by an imbalance between osteoblasts and osteoclasts. Diagnosis usually occurs through radiographic examination and/or CT scan. Objective: This study reports the treatment of a case of external cervical resorption with a multidisciplinary approach involving Endodontics, Orthodontics, Periodontics, and Prosthodontics. Methods: CT image revealed external cervical resorption in...

Introduction: As the need for complementary antimicrobial therapies arises, photodynamic therapy (PDT) shows promising results in the inactivation of microorganisms inside root canals. Objective: The aim of this study was to analyze the penetration capacity of a photosensitizer, i.e., methylene blue, inside the dentin at cervical, middle and apical levels of root canals of human teeth, while comparing different applications of the solution. Methods: The sample included 20 single-root...

The aim of this study was to assess, in vitro, and by means of four criteria (radiographic, macroscopic, microscopic and serial section), the amount and configuration of root canals in maxillary and mandibular premolars. It is a crosssectional observational and descriptive study, in which 100 premolars were selected. Exclusion criteria comprised teeth destroyed by caries, presenting previous endodontic treatment, incomplete root formation, resorption and/or fractures. The teeth were divided...

Introduction: The combination of suitable mechanical preparation, root canal disinfection and satisfactory filling is key for a favorable prognosis in endodontic treatment. The anatomical complexity of root canals is a limiting factor in instrumentation, and requires clinicians to carry out different procedures in order to achieve it. Objective: The aim of this study was to report a case of endodontic treatment of tooth #47, with complex anatomical traits and double root curvature in a...

Introduction: The solvent power of chemicals used in endodontic retreatment is an important property related to the quality of filling material removal. Objective: To compare the solvent power of five substances used in endodontic retreatment after contact with gutta-percha. Methods: A total of 18 gutta-percha cones (#80), weighed on a precision analytical scale and divided into six groups were used: I) chloroform; II) eucalyptol; III) xylol; IV) halothane; V) d’limonene; VI) saline...

Introduction: Some clinical situations do not present as ideal for proper restorative treatment, and the dentist must find alternative ways to properly access the gingival margin. Objective: The objective of this report is to present a case of cervical lesions with buccal exposure of root canals in which interaction among Endodontics, Restorative Dentistry and Periodontics was key to success. Case report: Patient presented with subgingival cervical carious lesions, with exposure of anterior...

Introduction: Intracanal dressings should be used because shaping and cleaning alone do not eliminate microorganisms adhered to the canal walls. In specific cases, treatment may have to be conducted over several visits, which may have an adverse effect because success depends on patient’s cooperation to return to the office several times. Thus, medication combinations are important, as they remain in the root canal for long periods of time. The activity of each substance is then preserved,...
