Pain referred to teeth, called odontogenic, is the most common orofacial pain, and its etiology often involves easily identifiable markers, such as caries, periodontitis, pulpitis and tooth trauma. The treatment of these painful conditions is directly associated with the resolution of these diseases and often includes invasive procedures, such as restorations, endodontic treatment or extractions. The elimination of etiologic factors will probably resolve pain, which is, in these cases,...

The data is alarming. According to a survey by ABIMO, of the more than 2 million dental implants made in Brazil, 30% are made with products with no provenance. The volume of irregular parts and components seized by the Federal Police without registration in ANVISA, under the scope of Operation Fake, which combats piracy and falsification in the dental sector, reaches 350 thousand.

was born in Araçatuba/SP, on September 16, 1978, son of Barcelo Angelo Cintra and Celeste Tavares Angelo Cintra. I studied in public schools and went to high school at Objetivo. In 1996, I passed the college entrance exam and, in 1997, I entered the Dentistry course at Araçatuba School of Dentistry - UNESP. At the end of 2000, I completed my undergraduate degree and was approved to enter the specialization in Endodontics at the same university. I did my specialization in 2001-2002 and, at the...

Introduction: Pulp calcification is one of the factors that make endodontic treatment challenging and capable of compromising access of instruments and irrigant solutions to the entire extension of the root canal, making it impossible to disinfect it adequately. Guided endodontics makes the endodontic treatment more predictable and safer in this complex situation. Materials and Methods: Once severe calcification requiring endodontic intervention has been found, the patient is referred to the...

Introduction: To radiographically evaluate the prevalence, extend and severity of root resorption in teeth adjacent to the cleft area after secondary alveolar bone graft. Methods: Radiographs of 200 individuals with unilateral and bilateral cleft lip, alveolus and palate were analyzed to investigate the presence of root resorption related with the bone graft. A total of 1315 radiographs were analyzed (periapical, occlusal and panoramic radiographs) obtained from 200 individials with complete...

Objective: The aim of this study was to compare the fracture resistance of four types of prefabricated intraradicular posts - glass fiber, glass fiber customized by composite resin, carbon fiber, and customized carbon fiber - on bovine teeth. Methods: Sixty bovine teeth were submitted to endodontic treatment and divided into the following groups: GF - glass fiber post; CGF - customized glass fiber post; CF - carbon fiber post; CCF - customized carbon fiber post; control - composite resin...

Objective: The aim of this study was to assess the influence of different concentrations of sodium hypochlorite (NaOCl) solution and of calcium hydroxide [Ca(OH)2] paste on the strength of root dentin during endodontic treatment. Methods: Eighty roots of bovine mandibular incisors were randomly assigned to eight groups: C- Control (no intervention); PS- Physiological saline; 1% NaOCl; 5% NaOCl; PS/EDTA; PS/EDTA/Ca(OH)2; 1% NaOCl/EDTA/Ca(OH)2; and 5% NaOCl/EDTA/ Ca(OH)2. All groups were...

Objective: To evaluate the maximum flexural strength (MFS), elastic modulus (E), Knoop microhardness (KHN), and surface roughness (Ra) of root dentin treated with 2% chlorhexidine (CHX) solution. Materials and methods: Fifty bovine incisors with closed apex were selected. Thirty roots were cut into dentin bars (DB) and divided into three groups (n=10): control (no treatment), G1 (2.5% NaOCl + 17% EDTA) and G2 (2% CHX + H2O). The DB were submitted to the three-point flexural strength test to...

Introduction: the frequency of invasive mycoses caused by opportunistic fungal pathogens has increased significantly in the last decades. Among the main etiological agents of opportunistic mycoses is Candida albicans. This yeast has several important virulence factors for producing disease. Some studies have demonstrated that C. albicans colonized root canals and dentinal tubules. The spectrum of antimicrobial activity of calcium hydroxide dressing should include this yeast. Objectives: the aim...

Introduction: When conventional root canal treatment does not achieve the desired results, paraendodontic surgery should be performed to remove the causes of the persistent periapical cyst, preserve the tooth, contribute to the adequate functioning of the stomatognathic system and return health and wellbeing to the patient. Methods: A 27-year-old male presented with the right maxillary lateral incisor (tooth 12) with persistent exudate even after treatment of the root canal and the exchange...

Introduction: The maintenance of a traumatized tooth in the oral cavity depends on a correct emergency treatment, as well as a long and adequate period of clinical-imaging follow-up. Objective: To report a clinical case of avulsion and replantation of tooth 11, in an 11-year-old child, who has been in the oral cavity for 13 years. Methods: tooth replantation 45 minutes after avulsion, endodontic treatment with 10 monthly exchanges of intracanal calcium hydroxide medication, followed by root...

Objective: This study presented a case of internal root resorption in a tooth with pulp necrosis that was submitted to endodontic treatment. In this treatment, an additional irrigation technique with a XP-Endo Finisher instrument was used during the chemical-mechanical preparation. Methods: After radiographic diagnostics and semi-technique tests, instrumentation was performed with Protaper universal system, activation of irrigation solutions, 2% chlorhexidine digluconate with the XP-Endo...

Introduction: Endodontic therapy should reduce the microbial load within the root canals, which can be achieved during chemomechanical preparation (CMP). The purpose of CMP of the root canal system (RCS) is to create a favorable environment for healing. CMP associates the mechanical action of instruments with the use of auxiliary chemical substances. There is no consensus among professionals about what should be the diameter of the apical foramen after CMP. This literature review evaluated the...
