Objectives: This study was an examination of the long-term results of transcanalicular laser (TCL) and external (EX) dacryocystorhinostomy (DCR).
Methods: Patients who had undergone TCL-DCR or EX-DCR between 2009 and 2013 were invited for long-term follow-up in 2019. All of the patients who responded had an ophthalmic examination and were assessed using lacrimal irrigation. An intranasal evaluation was performed when the irrigation test had non-patent results. TCL procedures were performed with a diode laser (980 nm). Ostium cleansing with a suction unit and a nasal endoscope was performed in the first week. In EX-DCR procedures, an anterior flap was created and tented to the orbicularis oculi muscle. A silicon tube was implanted in both methods and removed at 4-6 months.
Results: A total of 74 EX-DCR patients were assessed. The lacrimal irrigation test was negative in 5 cases. The functional success rate was 93.2% with a follow-up of 8 years. A total of 63 patients who had undergone TCL-DCR were evaluated and the irrigation test was negative in 9 patients. The functional success rate was 85.7% with a follow-up of 7 years. The difference in the success rate was statistically insignificant with a p value of 0.09.
Conclusion: The long-term success rates of both EX-DCR and TCL-DCR were high.

Background: Periapical extrusion of debris for root retreatment will effectively improve the posttreatment inflammation and pain. The aim of this study was to investigate the extruded debris for root retreatment using XP shaper and ProTaper files.
Materials And Methods: In his experimental laboratory study, 40 extracted human maxillary molars were used in this laboratory study.

Introduction: This study aimed to evaluate the antimicrobial efficacy of single-walled carbon nanotubes when combined with the commonly used intracanal medicaments by checking their zone of inhibition against .
Materials And Methods: The test materials were divided into five different groups, namely, Group I: single-walled carbon nanotubes; Group II: calcium hydroxide; Group III: chlorhexidine; Group IV: single-walled carbon nanotubes + calcium hydroxide; and Group V: single-walled carbon nanotubes + chlorhexidine. Five sterile Petri plates per group were inoculated with (); wells were made in the plates, one on each side, and a volume of 50 microliters of each solution was dispensed into individual wells using a pipette.

Lycium barbarum is an important economic crop in the arid region of Northwest China, and the regulation of irrigation and fertilisation is an important way to improve the quality and yield of Lycium barbarum. To explore the effects of water-fertiliser coupling on photosynthesis, quality and yield of Lycium barbarum under irrigation methods based on predicted crop evapotranspiration (ET), ET was calculated via reference evapotranspiration (ET) predicted on the basis of public weather forecasts, and the irrigation water volume was determined as a proportion of this ET. A field experiment was conducted via a completely randomised experimental design with five irrigation water volumes (W0 (100% ET), W1 (90% ET), W2 (80% ET), W3 (70% ET) and W4 (65% ET)) and three fertiliser application rates (high fertiliser (FH), medium fertiliser (FM) and low fertiliser (FL)).

Very high heat is generated during the polymerization of poly (methyl methacrylate) (PMMA) bone cement, which is used for implant fixation in orthopedic surgery. As such, it has been suggested that irrigating the bone cement layer in the surgical site with a saline solution is a way of cooling the layer. In this study, we aimed to determine the influence of irrigation with a saline solution on the flexural strength and the microstructure of the test specimens of two PMMA bone cement brands: Simplex P and FIX 1.

Agriculture 4.0 technologies continue to see low adoption among small and medium-sized farmers, primarily because these solutions often fail to account for the specific challenges of rural areas. In this work, we propose and implement a design methodology to develop a Precision Agriculture solution aimed at assisting farmers in managing water stress in Hass avocado crops.
