Ethical and Medico-Legal Considerations with Aesthetic Dentistry Involving the Aesthetic Zone.

The bedrock of delivering cosmetic dentistry remains good communication underpinned by a clear and transparent consent process. This article looks at this while exploring the ethical and risk management issues that have started to challenge the profession. While patients' demand for cosmetic dentistry has exploded, this article explores the ethical conundrums faced by these treatments against the backdrop of whether their happiness is affected by their image.

Grey Matters: 2006 and all that.

The article is intended to put the current NHS dental contract in england into context and identify areas where there has been confusion about interpretation of certain clauses. the article describes these as grey areas and provides a rationale for logically interpreting these issues, such as urgent treatment, mixing NHS and private treatment and defining what a course of treatment is.
These are the views of the authors based on significant personal experience of the contract, both as practitioners and as dento-legal advisers.

Monitoring erosive toothwear: BEWE, a simple tool to protect patients and the profession.

Erosive tooth wear is the third most commonly observed oral condition after caries and periodontal disease, with a prevalence similar to that of dentine hypersensitivity. However, it is not a condition that is routinely screened, or monitored, as part of the standard dental examination. Following a meeting held in 2018, this paper considers the outlook for erosive tooth wear and the need for dental professionals to monitor for signs of the condition as part of an oral health assessment, to provide protection for patients and the profession. The use of the basic erosive wear examination (BEWE) is proposed as a simple screening tool designed to detect erosive tooth wear in clinical practice.

Monitoring changes in soil organic carbon pools, nitrogen, phosphorus, and sulfur under different agricultural management practices in the tropics.

Soil organic matter not only affects sustainability of agricultural ecosystems, but also extremely important in maintaining overall quality of environment as soil contains a significant part of global carbon stock. Hence, we attempted to assess the influence of different tillage and nutrient management practices on various stabilized and active soil organic carbon pools, and their contribution to the extractable nitrogen phosphorus and sulfur. Our study confined to the assessment of impact of agricultural management practices on the soil organic carbon pools and extractable nutrients under three important cropping systems, viz. soybean-wheat, maize-wheat, and rice-wheat. Results indicated that there was marginal improvement in Walkley and Black content in soil under integrated and organic nutrient management treatments in soybean-wheat, maize-wheat, and rice-wheat after completion of four cropping cycles. Improvement in stabilized pools of soil organic carbon (SOC) was not proportional to the applied amount of organic manures. While, labile pools of SOC were increased with the increase in amount of added manures. Apparently, green manure (Sesbania) was more effective in enhancing the lability of SOC as compared to farmyard manure and crop residues. The KMnO(4)-oxidizable SOC proved to be more sensitive and consistent as an index of labile pool of SOC compared to microbial biomass carbon. Under different cropping sequences, labile fractions of soil organic carbon exerted consistent positive effect on the extractable nitrogen, phosphorus, and sulfur in soil.

Effect of amendments on the extractability, retention and plant uptake of metals on a sewage-irrigated soil.

Laboratory and greenhouse experiments were conducted to evaluate the effects of farmyard manure (FYM), CaCO(3) and single superphosphate (SSP) on retention and availability of Zn, Cu and Ni in sewage-irrigated soil. We also assessed the suitability of 0.05M EDTA for predicting the effectiveness of these amendments in reducing the phytoavailability of metals. Results indicated that EDTA could successfully predict the phytoavailability of Zn and Ni in amended soil, whereas it failed in case of Cu. By and large, application of CaCO(3), either alone or in combination with FYM had a positive effect on the retention of Zn, Cu and Ni in soil. Application of CaCO(3) alone or in combination with FYM was equally effective in reducing the Zn content in lettuce, whereas sole application of CaCO(3) significantly reduced Ni content. However, only SSP was found to be effective in reducing the Cu content in lettuce.
