The apical limit of root canal instrumentation has always been a matter great controversy. Despite the large number published studies on this subject, consensus not yet reached. In fact, recent discussion patency and cleaning foramen, as well incorporation these procedures to endodontic treatment, seem have raised even more polemics. It is likely that all polemics its roots in lack interrelation between theoretical knowledge pulp stump periapical tissues real clinical practice. By addressing...

Background and objectives: Pulp stones are hard tissue structures formed in the pulp of permanent deciduous teeth. Few studies have evaluated their morphology chemical composition. However, formation, composition, configuration role played overall health status still unclear. Clinically, they may be symptomatic; technically, impede access during endodontic therapy, increasing risk treatment errors. Thus, this study aimed to morphologically analyze present quantification, identifying main...

The purpose of this study was to evaluate if the apical third enlargement root canal is determinant factor for repair periapical lesions in endodontic treatment.Eighty upper and lower incisors, canines premolars with were randomly divided 2 groups treated by undergraduate students. Canals instrumented up 3 files group I (n = 40) 4 II 1 mm short apex filled a calcium hydroxide dressing. After removing 14 days later, both using lateral condensation technique. In 2-year follow-up, few patients...

Pulpotomy is a conservative therapy performed to remove the inflamed coronal portion of pulp and preserve vitality remaining radicular pulp. This article reports two cases immature permanent mandibular molars with clinical signs radiographic images periapical bone rarefaction, which were treated calcium hydroxide pulpotomy. In Case 1, pulpotomy was in single session, while 2 sessions required complete treatment. Clinical follow up within 13 9 months, respectively, showed hard tissue barrier...

Since instrumentation of the apical foramen has been suggested for cleaning and disinfection cemental canal, selection file size position have challenging steps. This study analyzed influence lateral opening can exert on canal instrumentation. Thirty-four human maxillary central incisors were divided in two groups: Group 1 (n=17), without flaring, 2 with flaring LA Axxess burs. K-files increasing diameters progressively inserted into until binding at was achieved tips visible bonded ethyl...

Aim: This article analyzed the location of apical foramen and its relationship with foraminal file size in maxillary central incisors. Methods: Eighty four human incisors were used this study. K-files progressively increasing diameters inserted into root canal until it got snugly fit tip was visible at foramen. The files removed teeth crosssectioned 10 mm from apex. then reinserted, fixed a cyanoacrylate-based adhesive, sectioned same level as root. apices examined using scanning electron...

Considering that instrumentation of the apical foramen has been suggested for root canal infection control, this study analyzed relationship between files bind at and foraminal openings in 50 maxillary central incisors. After preparation pulp chamber, access to was obtained with #1 2 LA Axxess K-files tip cut were inserted up until binding felt. The fixed methyl cyanoacrylate tooth-file sets cross-sectioned 10 mm short apex. Scanning electron microscopic analysis carried out areas measured...

Incidence of postoperative pain after instrumentation the cemental canal in teeth with necrotic pulp AbstRAct Introduction: Once infection control is considered key for endodontic treatment success, has been recommended cases necrosis.However, it believed that this procedure may result pain.Objective: The aim study was to analyze incidence following teeth.Methods: After 90 root canals, post-operative evaluated by means a visual analog scale.Data were processed and subjected statistical...

Besides the risk of filling material extrusion throughout apex, a satisfactory apical seal can be difficult to achieve in canals with open apices or iatrogenic enlargements constriction. These situations pose challenge root canal filling. This paper describes maxillary right canine an overinstrumented complete loss stop, extensive transportation and periodontitis. A 5 mm calcium hydroxide plug was placed before The made by soaking points saline, dipping powder then applying it apex several...

Complexity of root canal treatment is well recognized, however some specific situations are still more difficult, such as apical third with accentuated curvature. Nevertheless, recent techniques instrumentation and obturation brought new persperctives became a determinant factor for successful treatment. Through the maxillary left lateral incisor, curvature, pulpal necrosis periapical lesion through manual condensation technique filling, this article aimed to discuss whether these actually...

É reconhecida a complexidade do tratamento endodôntico. Algumas situações em particular apresentam características que podem representar dificuldades ainda maiores, entre as quais os canais curvatura apical acentuada, necrose pulpar e lesão periapical. Nesse sentido, novas técnicas de instrumentação obturação trouxeram perspectivas graças isso assumiram condição fatores determinantes sucesso. Através um incisivo lateral superior esquerdo com periapical, utilizando manual técnica da...
