“…This was in agreement with a previous study that assessed apical debris extrusion during the instrumentation of oval canals with either ProTaper Next files together with XP-endo Finisher or the self-adjusting file system and found that there was more apical extrusion of debris when XP-endo Finisher was used (42) . Also, it was proved that XP-endo Finisher resulted in apical extrusion of irrigant similar to that standard needle irrigation and significantly more than EndoVac irrigant activation technique (43) .…”

Purpose: This study was conducted to assess and compare the effect of XP-endo Finisher on post-instrumentation pain after using either One Shape single-file rotary system or ProTaper Universal multi-file rotary system in root canal preparation. Materials and Methods: Forty-eight consented patients, with 52 single-rooted teeth requiring endodontic treatment were selected for this study based on inclusion/exclusion criteria. Teeth were randomly assigned into two equal groups according to the NiTi rotary system used for root canal preparation, Group (I), One Shape rotary system was used and Group (II), ProTaper Universal rotary system was used. Each group was further subdivided into two equal subgroups (A and B) according to whether XPendo Finisher was used in finishing the root canal preparation or not. Pain Intensity was measured using modified visual analogue scale at 6, 12, 24 and 72 hours after root canal instrumentation. Results: The patients' highest mean pain scores occurred in the first 24 hours and significantly declined at the subsequent observation time of 72 hours. ProTaper Universal groups showed the highest mean pain scores, while the lowest mean pain scores were found in One Shape groups with no significant difference. The highest mean pain scores were found in XP-endo Finisher subgroups, while the lowest were found in No XP-endo Finisher subgroups with no significant difference. Conclusion: One Shape system produced less postoperative pain when used in conjunction with XP-endo Finisher.

“…It is known that the larger the apical diameter of the teeth, the higher the risk of damage to the periapical tissues (23). As consistently evidenced, the negative pressure irrigation system considerably reduces the inadvertent apical extrusion of debris and irrigation solution (24,25), emphasizing the biologically beneficial effects of its use in immature teeth. As an additional advantage, there is a better removal of the smear layer and necrotic material from the apical third of the canal lesion (5,6,26), considered the most heavily contaminated region, especially in the presence of periapical lesion.…”

The objective of this in vivo study was to assess the effect of the root canal irrigation by negative and positive apical pressure on the expression of molecules that are an indicative of cell differentiation with mineralizing phenotype in teeth of dogs with incomplete rhizogenesis and induced periapical lesion. A total of 30 teeth (60 roots) were distributed into 3 groups (n=20): EndoVac®, Conventional and Control. After 90 days, the routine histotechnical procedures were performed and the sections were submitted to immunohistochemical technique for the staining of osteopontin (OPN), alkaline phosphatase (ALP) and the RUNX2 transcription factor in the apical and periapical regions of the roots. A semi-quantitative analysis of the positive immunostaining was performed and the intensity of the expression was classified in absent (0), mild (1), moderate (2), or intense (3). Scores data were statistically analyzed by the Kruskal-Wallis non-parametric test and Dunn post-test, and the significance level was set at 5%. RUNX2 immunostaining revealed that in the negative pressure group there was a significantly stronger (p<0.05) immunostaining in comparison to the control group. Regarding the OPN expression, it was not possible to detect a statistically significant difference between the groups (p>0.05). After analyzing ALP immunostaining, a statistically significant difference was observed between the groups (p<0.05), and the negative pressure group showed a markedly stronger mark immunostaining than the control group. The results of the present in vivo study allowed concluding that negative apical pressure irrigation presents mineralizing potential in immature teeth with apical periodontitis.

“…A particular issue with PIPS is the extent of debris and NaOCl that can be extruded through the apex, when appropriate evacuation systems (such as negative apical pressure (EndoVac)), are not used simultaneously. More extrusion of material occurs using PIPS than when ultrasonic agitation is used [ 57 , 58 , 59 , 60 ].…”

In conventional endodontic treatment, alkaline solutions of sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid (EDTA) are used in combination to disinfect the root canal system and to eliminate debris and smear layers. An important concept that has emerged over recent years is the use of active physical methods for agitating these fluids to improve their penetration within areas that are not reached by endodontic instruments and to accelerate the chemical actions of these alkaline fluids against planktonic microorganisms, biofilms, soft tissue remnants and smear layers. Ultrasonic agitation and more recently pulsed lasers have emerged as two promising methods for activating endodontic irrigation fluids. Ultrasonic agitation with piezoelectric devices employs a moving tip, while laser agitation uses a stationary tip. Both methods cause cavitation, followed by implosions and shear forces which assist with debridement. Fluid streaming further enhances the activity of the fluids. While agitation enhances performance of irrigants, extrusion of fluids from the root canal during activation is a hazard that must be controlled.
