The endodontic success relies on chemo mechanical preparation, removal of microbial toxins, irrigation and complete obturation of the root canals. The key part of the treatment is hand and rotary instrumentation to eliminate microorganisms from the primary rootcanal by the action of direct mechanical cleaning.The maingoal of instrumentation is to facilitate disinfection,effective irrigation and filling.The intricacy of rootcanal morphology provides curved apical third,apical deltas, narrow isthmi, oval and ribbon shaped canals cannot be mechanically cleaned.Bacteria can flourish in these untouched areas and it turned out to be a challenging objective to endodontic and also a real cause for pulpal and periapical diseases.Complete disinfection of canal is difficult with single irrigating solution use of two or several irrigating solutions obtain the goals of effective and safe irrigation. Irrigation has been performed with plastic syringe it allows good control of needle depth. The purpose of this article is illuminate the methods of effective and safe irrigation on the latest advancements

Background: Irrigants and intracanal medicaments form a necessary adjunct that enhances the antimicrobial effect of mechanical cleansing and thus augments overall clinical efficacy. Hence; the present study was undertaken for analyzing and comparing the efficacy of three endodontic irrigating solutions against Enterococcus Faecalis.
Materials & methods: A total of thirty single rooted mandibular first premolar specimens were included. Sectioning of the specimens was done at cement-enamel junction level. Instrumentation of the root canals was done with rotary instruments to an apical size of ProTaper F3. Vertical sectioning of all the specimens was done along the mid-sagittal plane into two halves. All the specimens were divided into following study groups: Group A: 5% Sodium hypochlorite, Group B: 0.2% Chitosan and Group C: Saline. Inoculation of the bacterium was done in the broth in all the tissue culture wells. The biofilm on root canal surface was taken with a sterile scalpel and inoculated on agar plates and incubated. Colony forming units were then analyzed. Analysis of all the results was done using SPSS software.
Results: Mean CFU among specimens of group A, group B and group C were found to be 0.59, 2.118 and 90.184 respectively. While analyzing the results statistically, significant results were obtained.
Conclusion: Sodium hypochlorite exhibited maximum efficacy against Enterococcus Faecalis.

The article analyzes the state of agricultural lands in Uzbekistan and examines the reasons for their decline. It analyzes the issues of targeted and efficient use of irrigated agricultural lands and programs of measures to improve their reclamation, and makes relevant proposals for their more efficient use. It also analyzes the views of experts on the recognition of land use efficiency indicators in relation to key indicators, based on the fact that the same indicators can not be applied to different organizational and legal forms of land management, given the characteristics of specific and relative indicators of land use efficiency. In Namangan region, econometric models of changes in the volume of crop production depending on the reclamation conditions were developed and analyzed. The reclamation condition of the land as an indicator of land use efficiency was studied and conclusions were drawn on the introduction of mineral and organic fertilizers for crops in agricultural organizations.

Background: Apical extrusion of debris, irrigating solution and microorganism are always being concern for operator as these may cause flare-ups during root canal therapy. These noxious insults can also cause cell-mediated or humoral immunological phenomenon causing severe distress to the patient. Aim of this ex vivo study was to evaluate the effect of different types of instrumentation in combination with different irrigation methods on apical expulsion of debris and irrigating solution.
Material and Methods: Four hundred and ten extracted human permanent teeth were selected for the study. Ten teeth were kept as control group which were neither instrumented nor irrigated. Manual file (MF), protaper universal rotary (PTU), waveOne reciprocating(WO) and flexiCON rotary systems (FC) were used for instrumentation of the canals using two different irrigation techniques: conventional needle irrigation and endoVac irrigation. A single experienced operator carried out all the endodontic procedures. Four hundred teeth were equally divided in four groups (n = 100), in which instrumentation was performed using a MF (group 1), PTU (group 2), WO (group 3) and FC (group 4). In each group, 50 samples were irrigated with conventional needle irrigation, and 50 samples were irrigated with the endoVac irrigation method. During instrumentation, apically extruded debris and irrigating solution were collected in preweighed Eppendorf tube. Weight of expelled debris and volume of expelled irrigating 
solution were quantitatively measured individually. The data collected were statistically analysed.
Results: The group 1 showed highest extrusion of debris and irrigating solution while group 4 showed lowest. The order of sequence for debris expulsion from minimum to maximum is FlexiCON < waveOne < protaper < manual instrumentation. The order of sequence from minimum to maximum is FlexiCON < protaper < waveOne < manual instrumentation.
Conclusion: FlexiCON rotary instrumentation with the endoVac irrigation system produced significantly less debris and irrigating solution than the other techniques.
Clinical significance: This report highlights on how the apical extrusion of debris and irrigating solution can be minimised with altered instrumentation and irrigation technique for effective endodontic therapy
