Studies have suggested that formocresol has toxic and carcinogenic potential. A search for an alternative medicament for primary tooth pulpotomies has led to ferric sulfate as a possible alternative. A retrospective study was done in a multipractitioner IHS (Indian Health Service) clinic. Radiographic success or failure was determined for 202 primary tooth pulpotomies performed with either formocresol, ferric sulfate, or a combination procedure of formocresol and ferric sulfate. The post-operative period for the pulpotomies ranged from one month to thirty-six plus months. There was no statistical difference in radiographic failure rates between formocresol, ferric sulfate, or the combination procedure when results were analyzed regardless of post-op period. However, when post-op periods were considered, formocresol performed better at > 36 months and the combination procedure showed significantly more failures at > 36 months.

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).

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.
