Abstract Dental care substances with stannous fluoride as an active ingredient may be helpful in allowing re-hardening or in increasing the resistance of teeth surfaces to further acidic or mechanical impacts. However, stannous fluorides are applied together with brushing and depending on how and when tooth-brushing occurs. This research focuses on the potential harmful and helpful effects associated with the use of stannous concerning erosive wear. Active ingredients like fluorides or agents that have unique anti-erosive properties were shown to offer protection against erosion and combined erosion and abrasion to some extent. The abrasive effects of dentifrices may ...

There are many limiting factors in a marine ecosystem. These limiting factors interact in many ways to form different features and also affect the marine ecosystem. This paper analyzes the relationship between the temperature of the region and rate of evapotranspiration, the upwelling of water and the speed of wind, the ocean currents and the climate experienced, and nature of rocks and type of features formed. The temperature of the surrounding region in an ocean is very important. When temperature is high, the evaporation from the surface of the ocean would be high (NSIDC, n.d). In addition, high temperature ...

Role of the integumentary system in protecting the body

Introduction Human body, like all higher order vertebrates, relies on multiple organ systems for maintenance of homeostasis, the integumentary system is but one of them. Anatomically, the integumentary system has two components :the cutaneous membrane(the skin) and its accessory structures. The skin comprises of the dermis and epidermis whereas the later include hair, nails, and exocrine glands located in the dermis. Interestingly, both the cutaneous and accessory structures share a common embryological origin: The ectoderm (Martini 2005, p.151). With respect to functioning, the skin is involved in a variety of physiologic functions, the most obvious being protection of the ...

As can be seen from sources the Smoking ban doesn’t necessarily imply positive ends via a means that isn’t verified. Some of the impositions that have been made by the campus institutions do not necessarily go ahead and showcase that a ban is as necessary as the reasons behind its instatement. Hereby we can well assume that with the factors in place bans may not be the best way to address the issue of smoking in institutions. Some factors need to be well put into consideration before making any prior decisions that will affect the smokers in the campus ...
