Objective: To evaluate the effects of zinc oxide-eugenol, calcium hydroxide, and mineral trioxide aggregate as base materials on the clinical and radiographic success of ferric sulfate pulpotomies in primary molars.
Method And Materials: Following hemostasis with 15.5% ferric sulfate, 105 teeth were randomly allocated to three groups: Group 1, zinc oxide-eugenol; Group 2, calcium hydroxide; and Group 3, mineral trioxide aggregate. All teeth were restored with stainless-steel crowns. Clinical and radiographic examinations were conducted at 6, 12, 18, and 24 months.
Results: After 24 months, clinical success rates for Groups 1 to 3 were 97.1% (34/35 teeth), 94.2% (33/35 teeth), and 97.1% (34/35 teeth), respectively (P > .05). Radiographic success rates were 65.7% (23/35 teeth), 65.7% (23/35 teeth), and 77.1% (27/35 teeth), respectively (P > .05). Internal resorption was the most observed radiographic finding (15/105 teeth).
Conclusions: The choice of zinc oxide-eugenol, calcium hydroxide, and mineral trioxide aggregate, as base materials, did not affect the clinical and radiographic success of ferric sulfate pulpotomies in primary teeth.

[Comprehensive Analysis and Emission Reduction Pathway of GHG Emissions at a Wastewater Treatment Plant in Suzhou].

Taking a sewage treatment plant in Suzhou City, Jiangsu Province, as an example, the greenhouse gas （GHG） emissions generated in the sewage treatment system were calculated using the carbon balance method and the emission factor method. The environmental impacts and economic aspects of different treatment units in wastewater treatment plants were analyzed using life cycle assessment, cost-benefit analysis, and data envelopment analysis models, and emission reduction pathways were proposed. The results indicated that the total GHG emissions （in terms of CO） from a certain municipal wastewater treatment plant in Suzhou were 6 653.

Statement Of The Problem: Success of pulpotomy of primary teeth depends on biological and cytotoxic effects of pulp capping agents. Mineral trioxide aggregate (MTA), Biodentine, calcium enriched mixture (CEM) cement, and ferric sulfate (FS) are among the commonly used pulp capping agents (PCAs) for pulpotomy, and their successful application has been previously evaluated.
Purpose: This study aimed to compare the cytotoxicity of PCAs against mesenchymal stem cells isolated from human exfoliated deciduous teeth (SHEDs).
Phase conversion characteristics of lead sulfate in ferric sulfate medium.

Article Synopsis
- - The study focused on how various factors like temperature, sulfuric acid concentration, and different sulfate concentrations affect the transformation of lead sulfate (PbSO) into lead jarosite (Pb-J) in a sulfuric acid system.
- - Results showed that the temperature threshold for converting PbSO to Pb-J decreased from 150 to 90 °C as sulfuric acid concentration dropped from 20 to 5 g/L, while high sulfuric acid concentration (over 40 g/L) kept PbSO stable without significant conversion.
- - Additionally, higher concentrations of ferric iron promoted Pb-J formation, while sodium and potassium sulfates inhibited it, leading to the formation of specific jarosites (K-J and Na-J) instead
The effect of hemostatic agents and dentin cleansing protocols on shear bond strength of resin composite using universal adhesive: an in vitro study.

Article Synopsis
- Hemostatic agents are commonly used in dental procedures to control bleeding, but they can negatively impact the bonding of resin composites to dentin, making their removal before bonding important.
- The study involved 90 premolar teeth divided into groups treated with either no hemostatic agent, ferric sulfate, or aluminum chloride, with cleanup methods including water, phosphoric acid, katana cleaner, and air abrasion.
- Results showed that the type of hemostatic agent and cleansing method significantly affected bond strength, with phosphoric acid yielding the best results and ferric sulfate showing the lowest bond strength.
The Gypsum Influence on the Formation of Secondary Phases During Autoclave Leaching of Gold-Bearing Concentrates and the Silver Recovery Using Cyanidation.

Autoclave leaching of sulfide concentrates may produce various ferric secondary phases, depending on the arsenic content and temperature. Silver is converted to argentojarosite, from which it is not recoverable by standard cyanidation methods. To increase silver recovery, it is necessary to reduce the argentojarosite formation during autoclave leaching.
