The analysis of research methods and results on resistance of nickel-titanium endodontic instruments to torsion load: the systematic review

Relevance. The objective of this study was to analyze current data concerning research methods and results on resistance of nickel-titanium endodontic instruments to torsion load in order to minimize complications of dental root canal treatment. The use of the nickel -titanium endodontic instruments is a special importance to ensure high-quality dental root canal treatment; it prevents the further contamination of the canals with microorganisms. However, these instruments can form a fracture under torsional load which leads to further complications.Aim. The analysis of research methods and results on resistance of nickel-titanium endodontic instruments to torsion load for minimization complications.Materials and methods. A series of publications in the electronic databases such as Google Scholar, Pub Med was analyzed in the course of a systematic review of the literature. The articles dealing with nickel-titanium endodontic instruments and torsion load that directly influences the quality of dental root canal treatment were included in the paper.Results. 73 articles were viewed during the review. Having analyzed the literature for inclusion criteria, the total number of publications has become 51. There were 16 main methods which demonstrated the influence of torsion load on endodontic instruments. These methods were summarized in the Table 1.Conclusions. As regards literature data, there are a various number of methods which converge to one conclusion: nickel-titanium instruments cannot fully resist torsion load. Fracture is caused approximately in 0,5-5% of cases.

Harmful Effects

The aim of this review article is detailed analyzation of the effect of sodium hypochlorite on the structural components of dentin. This compound is one of the strongest antimicrobial medicines for root canal treatment. However, sodium hypochlorite in certain concentrations has a detrimental effect on dentin, which leads to the loss of its physicochemical properties.Materials and methods. The study of publications was produced in the electronic databases such as Google Scholar, PubMed and ScienceDirect in the course of a systematic review of the literature. Included articles contain information about the on the effect of sodium hypochlorite on the structural components of dentin and the harmful effects of medicines for root canal treatment on organic elements.Results. 67 articles were viewed during the rview. After analyzing the literature for inclusion criteria, the total number of publications has become 43.Conclusions. According to the literature, it can be assumed that an increase in sodium hypochlorite concentration and its exposure time can lead to depletion of dentin organic matrix, which in turn, is responsible for the root fracture.

Irreversible Pulpitis

Background and Objectives: Symptomatic irreversible pulpitis in permanent mature teeth is a common indication for nonsurgical root canal treatment (NSRCT), but contemporary studies have reported on vital pulp therapy (VPT) applied in such teeth as a less invasive treatment. This systematic review assessed the outcomes of VPT, including partial and full pulpotomy performed with hydraulic calcium silicate cements (HCSCs) in permanent mature posterior teeth diagnosed with symptomatic irreversible pulpitis. Materials and Methods: The PRISMA guidelines were followed. The search strategy included PubMed®, EMBASE, Cochrane library and grey literature electronic databases. The quality assessment of the identified studies followed the Cochrane Collaboration Risk of Bias, ROBINS-I and Newcastle–Ottawa Scale tools. Results: The search of primary databases identified 142 articles, of which 9 randomized controlled trials and 3 prospective cohort studies were selected for review. The risk-of-bias was assessed as ‘high’ or ‘serious’, ‘fair’, and ‘low’ for three, seven and two articles, respectively. One to five years after VPT using HCSCs, the success rates mostly ranged from 78 to 90%. Based on two articles, the outcomes of the VPT and NSRCT were comparable at one and five years. Despite the necessity for the intra-operative pulp assessment in VPT procedures, the majority of the studies did not fully report on this step or on the time needed to achieve hemostasis. Small sample sizes, of under 23 teeth, were reported in three studies. Conclusions: The reviewed 12 articles reported favorable outcomes of the VPT performed with HCSCs in permanent mature posterior teeth with symptomatic irreversible pulpitis, with radiographic success in the range of 81 to 90%. Two articles suggested comparable outcomes of the VPT and root canal treatment. Universal case selection and outcome criteria needs to be established for VPT when considered as an alternative to NSRCT. This evidence supports the need for further research comparing longer-term outcomes of both of the treatment modalities.

Background: As people age, they become increasingly vulnerable to the untoward effects of medicines due to changes in body systems. These may result in medicines related problems (MRPs) and consequent decline or deterioration in health. Aim: To identify MRPs, indicators of deterioration associated with these MRPs, and preventative interventions from the literature. Design and Setting: Systematic review of primary studies on MRPs originating in Primary Care in older people. Methods: Relevant studies published between 2001 and April 2018 were obtained from Medline (via PubMed), CINAHL, Embase, Psych Info, PASCAL, Scopus, Cochrane Library, Science Direct, and Zetoc. Falls, delirium, pressure ulcer, hospitalization, use of health services and death were agreed indicators of deterioration. The methodological quality of included studies was assessed using the Down and Black tool. Results: There were 1858 articles retrieved from the data bases. Out of these, 21 full text articles met inclusion criteria for the review. MRPs identified were medication error, potentially inappropriate medicines, adverse drug reaction and non-adherence. These were associated with indicators of deterioration. Interventions that involved doctors, pharmacists and patients in planning and implementation yielded benefits in halting MRPs. Conclusion: This Systematic review summarizes MRPs and associated indicators of deterioration. Appropriate interventions appeared to be effective against certain MRPs and their consequences. Further studies to explore deterioration presented in this systematic review is imperative.

Background, Objectives, and Measurements Patients with chronic airway obstruction (CAO) frequently experience dyspnea and fatigue during activities performed by accessory muscles of ventilation, which competitively participate in arm elevation. This systematic review of randomized controlled trials (RCTs) concerning patients with CAO addresses the effects of upper-extremity exercise training (UEET), added to lower-extremity training or comprehensive pulmonary rehabilitation, on the following patient-centered outcomes: exercise capacity, symptoms, ability to perform daily activities, and health-related quality of life. Methods Studies were retrieved using comprehensive database and hand-search strategies. Two independent reviewers determined study eligibility based on inclusion criteria. A detailed description of treatments was mandatory. Reviewers rated study quality and extracted information on study methods, design, intervention, and results. Results Forty publications were evaluated. Four RCTs met the inclusion criteria but had serious methodological limitations, which introduce possible biases that reduce their internal validity. The outcomes measured were heterogeneous, and the results were inconsistent regarding maximal exercise capacity, dyspnea, and health-related quality of life. No effect of UEET was demonstrated for measures of arm fatigue. Limitations and Conclusions The limited methodological quality of the studies retrieved prevented us from performing a meta-analysis, the results of which could be misleading. This systematic review shows that there is limited evidence examining UEET and that the evidence available is of poor quality. Therefore, a recommendation for the inclusion or exclusion of UEET in pulmonary rehabilitation programs for individuals with CAO is not possible. Further research is needed to definitively ascertain the effects of this training modality on patient-centered outcomes.

Abstract Introduction The Accreditation Council for Graduate Medical Education (ACGME) introduced the Outcome Project in July 2001 to improve the quality of resident education through competency-based learning. The purpose of this systematic review is to determine and explore the perceptions of program directors regarding challenges to implementing the ACGME Outcome Project. Methods We used the PubMed and Web of Science databases and bibliographies for English-language articles published between January 1, 2001, and February 17, 2012. Studies were included if they described program directors' opinions on (1) barriers encountered when attempting to implement ACGME competency-based education, and (2) assessment methods that each residency program was using to implement competency-based education. Articles meeting the inclusion criteria were screened by 2 researchers. The grading criterion was created by the authors and used to assess the quality of each study. Results The survey-based data reported the opinions of 1076 program directors. Barriers that were encountered include: (1) lack of time; (2) lack of faculty support; (3) resistance of residents to the Outcome Project; (4) insufficient funding; (5) perceived low priority for the Outcome Project; (6) inadequate salary incentive; and (7) inadequate knowledge of the competencies. Of the 6 competencies, those pertaining to patient care and medical knowledge received the most responses from program directors and were given highest priority. Conclusions The reviewed literature revealed that time and financial constraints were the most important barriers encountered when implementing the ACGME Outcome Project.
