“…Different degrees of absorption capacity were found in the three commercial brands analyzed in the present study, which is similar to the findings described by Pumarola-Suñe et al [6]. This result may be explained by differences in fabrication processes and lots as well as the material used to make the points, paper solubility and the glue used by different manufacturers.…”

“…Very few studies [1,[5][6][7][9][10][11][12][13][14] report absorption property of absorbent paper points. There is also a lack of standardization in the study protocols, which describe methods with no specific nomenclatures, thereby hindering comparisons between studies [7].…”

“…Drying root canal is therefore an important step for successful hermetic sealing, given that adhesion are altered by moisture. Standardized absorbent paper points are extensively used in endodontic therapy following irrigation in order to dry the wall of the root canal [6]. Paper points are also used to apply intracanal medication, remove microbial cultures from the canal and as an indicator of the quality and color of the canal exudate [7].…”

“…Less time and fewer points are needed to dry root canals when paper point exhibits greater absorption capacity [8]. Few studies report on absorption capacity of paper points [1,5,6,9,10]. Pereira et al [7] analyzed two different methods for assessing absorption capacity of absorbent paper points.…”

A BSTR A CTdifferent brands of standardized absorbent paper points, testing the hypothesis that there is a positive correlation between the percentage of increased absorption capacity and sterilization method. Standardized endodontic absorbent paper points (size rank from #15 to #40) from three different brands of three manufacturers were used for this study (Dentsply, Endopoints, Tanari). Twenty absorbent paper points of each size were used. The initial weight (iw) of each absorbent paper point was recorded using a digital scale. After sterilization, the dry weight (dw) of each absorbent paper point was determined. Each paper point was then introduced into a 2% methylene blue solution during 20 seconds until complete saturation. The paper points were removed from the solution and the wet weight (ww) was determined, with absorption capacity calculated from a difference between ww-dw. Data was statistically analyzed using Tukey's test and the Student's t-test (p<0.05). Tanari paper points exhibited the best absorption capacity among the brands analyzed, but the difference K EYWORDS

A systematic review of methods used to sample and analyse periradicular tissue fluid during root canal treatment

et al. 2019

Aim The primary aim was to identify techniques used to sample and analyse periradicular tissue fluid (PTF) in permanent teeth diagnosed with apical disease during root canal treatment. Secondly, to identify the types of inflammatory mediators studied using this approach. Methodology Data Sources: PubMed, EMBASE, Cochrane Library, Science Direct, Web of Science and OpenGrey. Eligibility Criteria: Clinical studies published until 1 June 2018 which utilized orthograde techniques to sample and analyse PTF were included. Cell culture, laboratory or animal studies and those concerned with investigating inflammatory mediator activity from within healthy or diseased pulp tissue, and not periradicular tissues, were excluded. Study appraisal and methods: In accordance with PRISMA guidelines, data were extracted on study characteristics, target mediators, sampling and assay techniques and the parameters associated with the PTF sampling and eluting protocol. A qualitative synthesis was conducted, and studies were critically appraised using a modified version of the Cochrane risk of bias tool. Results Study Characteristics: From 251 studies, 33 were eligible for inclusion. Sampling techniques included the use of paper points (n = 27), fine needle aspiration (n = 4) and filter strips (n = 2). Assay techniques included enzyme‐linked immunosorbent assay (n = 18), quantitative polymerase chain reaction (n = 9), radioimmunoassay (n = 4), colorimetric assay (n = 2), immunofluorometric assay (n = 1) and cytometric bead array (n = 1). Forty‐five different inflammatory mediators were targeted at the proteomic/metabolomic (n = 25) or transcriptomic level (n = 9). Limitations: Significant heterogeneity exists within the methodology, and only 5 studies disclosed unambiguous information about their PTF sampling and eluting protocols. Conclusions Paper points and proteomic/metabolomic analysis are currently the preferred methods for studying and analysing PTF during root canal treatment. The most studied analytes were IL‐1β and TNF‐α. Implications: Further research is required to develop an optimized PTF sampling and eluting protocol to overcome methodological heterogeneity, and future studies are advised to follow a standardized approach to reporting their methodology.

Electroextraction (EE) encompasses a range of sample preparation methods whose effectiveness, selectivity, and efficiency are significantly influenced by the physical‐chemical characteristics of analytes, samples, and instrumental conditions. This article explores, for the first time, various strategies aimed at enhancing the extraction efficiency of a recent approach of EE utilizing a paper point (PP) combined with a hollow fiber (HF) (abbreviated as PP‐HF‐EE) to extract various cationic and anionic model compounds from water samples. The study also explores, experimentally, the impact of agitation, organic filter composition, PP diameter, and PP brand on extraction performance, and proves that all these factors are quite important, especially when digital image analysis is utilized for determination. Furthermore, this work demonstrates the ease and feasibility of simultaneously extracting cations and anions using PP‐HF‐EE and proposes a straightforward method to enhance analyte concentration on the vertex of the PP through a base‐to‐vertex focusing. Lastly, it is demonstrated, using capillary electrophoresis coupled to a UV‐Vis detector, that for PP‐HF‐EE, the extraction efficiency and pre‐concentration factor are less dependent on other parameters when multiple PPs per sample are utilized, with signal enhancement values of up to 111 and 339 for nortriptyline and haloperidol, respectively. All the findings and strategies presented herein constitute significant contributions that can facilitate future research in method development, particularly in the utilization of PP‐HF‐EE and similar EE approaches.
