Saliva is commonly referred to as the blood stream of the oral cavity. It has many functions, one of the major functions being protection of teeth against dental caries. There are many components in saliva, each one having a specific role in the prevention of dental caries. The composition of saliva varies from individual to individual and in the same individual it varies between the glands. The composition of whole saliva, especially when unstimulated, has gained much interest, because it is this which constantly bathes the teeth. The aim of this study was to determine the IgA levels in the unstimulated whole saliva of caries-free and caries-active children aged 3-6 years and to correlate its role in protection of the tooth against dental caries.

One of the most frequent reasons for seeking dental care is discolored anterior teeth. Macroabrasion is a technique used for the removal of localized superficial white spots and other surface stains. This article has compiled three case reports with relevant clinical photographs of discolored teeth where the treatment regimen included macroabrasion alone as well as macro-abrasion in combination with anterior composite restorations.
