Irrigation is an essential part of root canal treatment because it improves the debridement and disinfection of areas that tools are unable to thoroughly clean. Remote parts of the root canal system are frequently difficult to clean using irrigation that is mostly done with a syringe and a needle. As a result, various more complex techniques have been introduced. Ultrasonic irrigant activation is probably the most widely used adjunct method, and it has been compared with syringe irrigation in multiple studies. However, very few attempts have been made to summarize the available evidence.
Aim: The purpose of this study was to compare the effectiveness of ultrasonic irrigant activation during primary root canal treatment of mature permanent teeth to syringe irrigation in terms of cleansing and disinfecting root canals and healing of apical periodontitis.
Methods: An electronic search was conducted of the Cochrane Library, Embase, PubMed, Web of science and Scopus databases using both free-text key words and controlled vocabulary. Additional studies were sought through hand searching of endodontic journals and textbooks. The retrieved studies were screened by 2 reviewers according to predefined criteria. The included studies were critically appraised, and the extracted data were arranged in tables.
Results: The manual and automated searches turned up 957 titles, out of which 8 articles were selected for the systematic review. This evaluation comprised of randomized trials and in vitro research. In comparison to syringe irrigation, ultrasonic activation did not speed up the healing of apical periodontitis in teeth having a single root canal. The in vitro microbiological research reported a range of contradictory findings. Ultrasonic activation was superior to syringe irrigation in the removal of pulp tissue fragments and hard tissue debris.
Conclusion: As a result of inadequate evidence that was provided, no firm clinical recommendations could be made although ultrasonic activation does provide an alternate debridement mode in curved root canals

This article describes the changes in fiber waste from the technological flow in ginning plants, how much it changes in the stages of the technological process. The dust released in the drying and cleaning shop is only 5-7 mg/m3 of dust, which is less than the air in the building where the drying equipment is located. Large dispersed dust particles separate even at high humidity and sink to the surface of the building without being able to spread. In drying units, dust emitted in conjunction with an atmospheric drying agent causes discomfort. Although this dust is coarsely dispersed, it escapes in the dryer along with the air stream and settles near the roof of the building and near the drying shop. The amount of dust emitted was found to be 500-600 kg per day. In the ginning unit, the released dust is released into the atmosphere from the cotton pneumatic transport system, which is formed in the air in the drying and cleaning shop, as well as in the cleaning of cotton in the cleaning machines. It is a dusty fiber with less mineral fractions. The fine fractions are mainly composed of crushed dirty particles. It was found that only one ginnery produces 150-350 tons of fibrous waste per year, depending on the type of cotton, 5-6 tons of non-recyclable waste, 70-90% of non-recyclable waste is organic waste. It serves as a raw material for the use of waste as feed for livestock in agriculture. The results of scientific research conducted at the enterprise “Zarbdor Pakhta Tozalash” JSC in Jizzakh region to determine the amount of waste from ginneries have been processed.
