REVIEW
Kauko K Mäkinen
Sugar alcohols (polyols) are used in food manufacturing and in medical tests and examinations. d-Glucitol (sorbitol) and d-mannitol were previously the most common alditols used for these purposes. After the 1960s, xylitol became a common ingredient in noncariogenic confectioneries, oral hygiene products, and diabetic food. Erythritol, a polyol of the tetritol type, can be regarded as the sweetener of the "next generation." The disaccharide polyols maltitol, lactitol, and isomalt have also been used in food manufacturing and in medical tests...

Background. Oral mucocele is a common lesion resulting from an alteration of minor salivary glands due to mucus accumulation. Rapid appearance, specific location, history of trauma, bluish colour, and consistency help in the diagnosis. Conventional surgical removal is the treatment of choice but has several disadvantages like damage to adjacent ducts with further development of satellite lesions. Therefore, the present study was undertaken to evaluate the efficacy of intralesional corticosteroid injection (betamethasone) as a nonsurgical treatment procedure in oral mucoceles...

The microbial etiology of dental caries is still debated. Among the hypothesized contributors are the "low pH streptococci," a designation given to unusually acid proficient strains among the primary plaque colonizers S. oralis, S. mitis, S. gordonii, and S. anginosus. However, accurate assignment of species is difficult among the oral streptococci. Our objective was to develop a streamlined method for identifying strains of S. oralis and S. mitis from plaque samples so that they could be analyzed in a separate study devoted to low pH streptococci and caries...
