2. Apical Debris Extrusion by Novel Endostar E5 Compared to Other Commercial Rotary Files: An in Vitro Study
Abstract Objective: To compare the amount of apical debris extrusion in samples instrumented by EndoStar E5, ProTaper Universal, and M-two rotary files. Material and Methods: Forty-five freshly extracted non-carious mandibular premolar teeth with single roots and single canals were acquired, and randomly divided into 3 groups (n=15). Samples in Groups 1, 2

4. Debris extrusion and foraminal deformation produced by reciprocating instruments made of thermally treated NiTi wires
Abstract Objective To evaluate the amount of apically extruded debris, percentage of foraminal enlargement and apical foramen (AF) deformation that occurred during root canal preparation with different reciprocation systems: Reciproc, WaveOne (M-Wire), and ProDesign R (Shape Memory Technology Wire) at two different working lengths (WLs): 0.0 and 1.0 mm beyo

5. Anterior six arms prolene mesh for high stage vaginal prolapse: five years follow-up
ABSTRACT Introduction In high stage vaginal prolapse, recurrence risk patients, anterior and apical defects need to be addressed in the same procedure. The pre-molded commercial mesh kits are expensive and not always available. Alternative effective and safe treatment ways, with lower costs are desirable. Objective To present long term follow-up of patie

6. Apical Extrusion of Debris and Irrigants Using Different Irrigation Needles
Resumo Este estudo avaliou a influência do tipo de agulha de irrigação, curvatura do canal radicular e diâmetro apical final sobre a extrusão de detritos e solução irrigadora durante o preparo físico-químico do canal radicular. O canal mésio- vestibular de 90 molares foi instrumentado, após ser classificado como de curvatura leve ou moderada. Os d

7. Influence of Apical Preparation Size and Working Length on Debris Extrusion
Resumo Este estudo avaliou quantitativamente a quantidade de material extruído apicalmente pela instrumentação com lima única reciprocante, aplicando diferentes comprimentos de trabalho e tamanhos de preparo apical. Para a análise de extrusão foram utilizados oitenta incisivos inferiores unirradiculares humanos. Cavidades de acesso convencionais foram

8. Assessment of apically extruded debris and irrigant produced by different nickel-titanium instrument systems
The aim of this study was to evaluate the preparation time and the amounts of apically extruded debris and irrigant using different nickel-titanium instrumentation systems. Forty-five extracted single-rooted mandibular premolar teeth were selected and divided into three groups. The root canals were instrumented according to the manufacturers’ instructions,

9. Effect of needle insertion depth and apical diameter on irrigant extrusion in simulated immature permanent teeth
The aim of this study was to compare the amount of irrigant extrusion in simulated immature permanent teeth when the apical diameter and needle insertion depth were varied. Thirty single-rooted maxillary incisors with straight root canals were selected. The root length was standardized to a length of 9 mm. The teeth were divided into two experimental groups

10. Influence of Apical Patency and Cleaning of the Apical Foramen on Periapical Extrusion in Retreatment
Este estudo verificou a influência da patência apical, técnica de desobturação e limpeza foraminal na quantidade de material sólido extruído, durante retratamento endodôntico. Quarenta incisivos inferiores foram divididos aleatoriamente em quatro grupos - GIM (n=10), GIIM (n=10), GIPT (n=10) e GIIPT (n=10) - nomeados de acordo com a realização (I)

12. Influence of apical enlargement in cleaning and extrusion in canals with mild and moderate curvatures
Este estudo avaliou, in vitro, por meio de microscopia óptica e morfometria, a limpeza da região apical em canais radiculares com curvatura leve e moderada submetidos ao preparo biomecânico com sistema rotatório, bem como avaliou a quantidade de material extruído para a área apical. Incisivos laterais (n = 32), sendo 16 com ângulo de curvatura igual o
