A longitudinal study was carried out in order to evaluate the caries incidence as affected by partial substitution of dietary sucrose (S) with xylitol (X), the effects of S- or X-containing chewing gums being compared during one year. The material comprised initially 102 young adults, predominantly dental and medical students, divided randomly into S- and(More)

The effect on caries incidence of the daily consumption of chewing gum sweetened with sucrose or xylitol was measured in 100 subjects included in the 1-year chewing gum study (Scheinin et al. 1975, Turku sugar Studies XVIII). The subjects were divided retrospectively into groups consuming 2-8 chewing gum pieces per day and their caries incidence was(More)
The aim was to study eventual physico-chemical changes occurring in whole saliva due to sweetened and unsweetened stimulators. The assay was carried out in 10 female subjects with regard to changes of pH, buffering capacity and electrolytes in saliva as influenced by chewing of fructose, sucrose, sorbitol and xylitol gum, gum base and paraffin. The flow(More)

The purpose of the present study was to quantitate changes in buccal white-spot lesions during sucrose and xylitol consumption. Standardized color macrophotographs of white-spot lesions were taken 7 months after the beginning and at the end of the 2-year study. The quantification was based on the planimetry of these photographs. The area of white-spot(More)

The effects of chewing gums and chew tablets sweetened with sucrose or xylitol on the quantity and adhesivity of dental plaque were studied with 14 volunteer dental students (mean age 23.2). The subjects participated in a four-phase study in which one of four different test products was used during each period. The 3-d periods were interspaced with 4-d(More)
The aim of this study was to develop a planimetric, automatic method for evaluation of the extension and volume of plaque. Series of color macrophotographs of stained plaque were analyzed with a digitizer entering Cartesian coordinate data from the graphic records in a calculator. Estimations were carried out on the reproducibility, discriminatory power,(More)
An investigation was made of the effects on some biochemical characteristics of human whole saliva and dental plaque resulting from the daily consumption of three commercial, acid-containing beverages. The beverages tested were a cola beverage ("Coca-Cola"), a carbonated orange drink ("Jaffa") and single strength orange juice. Each of the three test(More)
Syrup-form medicines have been shown to cause dental caries in chronically sick children. The acid production of 10 syrupy medicines sweetened with sucrose, fructose, sorbitol, xylitol and saccharin or with a combination of these was tested. The subjects consisted of 7 dental students with low buffering capacity and high levels of Streptococcus mutans. The(More)
