Toothbrushing with the root of Euclea natalensis.

The custom of cleaning teeth and the gums with a chewed root of the tree Euclea natalensis, in the belief that it benefits oral health, is practised in South Africa by married women of an African Zanzibari community. The root of E. natalensis contains naphthoquinones which are bactericidal and, as they are also pigments, the mouths of the root users are stained bright orange. Samples of fresh root were tested against Streptococcus mutans and organisms in saliva and from deep periodontal pockets. Aerobic as well as anaerobic bacterial growth was suppressed in all instances. In addition we compared the plaque index (Silness et Löe), the periodontal index (CPITN), the DMFT and the state of the oral mucosa of root users and non-users. No significant differences were recorded in any of the variables. Although the beneficial effects claimed for this custom may have scientific validity, it is concluded that the daily practice is too limited to have a demonstrable beneficial effect.

[Evaluation of toothbrushing in a group of 531 school aged children].

Data concerning the evaluation of tooth brushing collected during odontostomatological screening in Val Pellice are reported. The screening was carried out by a dental team from Turin's Mauriziano Hospital and covered a population of 531 children aged between six and twelve.

Effect of chlorhexidine-sodium fluoride gel applied by tray or by toothbrush on salivary mutans streptococci.

A chlorhexidine (1%)-sodium fluoride (0.2%) gel applied using a dental tray six times during two consecutive days significantly decreased salivary levels of mutans streptococci but had only a slight effect on salivary levels of lactobacilli. The same gel used as a dentifrice for one week (twice a day) also significantly reduced salivary levels of mutans streptococci. However, this treatment was somewhat less effective than that using trays, on the basis of the ratio of mutans streptococci to total aerobes. With both treatments baseline salivary levels of mutans streptococci were re-attained after 70 days. One day after the gel treatment, mutans streptococci were unable to adhere to plastic strips (Dentocult SM Strip mutans) but detectable growth was found on mitis-salivarius-bacitracin agar. This suggests that not only are numbers of mutans streptococci reduced after chlorhexidine-sodium fluoride gel treatment but also mutans streptococci adherence.

[Investigation into the actual condition of outpatients. II. Correlation between the daily habits of eating and toothbrushing and the prevalence of dental caries incidence].

The purpose of this paper was to investigate the correlation between the daily habits of eating and tooth-brushing and the prevalence of dental caries in the outpatients who visited the Pedodontics Clinic of the Tohoku University Dental Hospital during the period from April 1981 to March 1986. The subjects were 877 individuals with questionnaires which the mothers had filled out. The following findings were obtained. 1) The dft index for children aged 1 year to 6 years in the present investigation was lower than that of the same age group investigated 10 years ago. 2) The dft indicies according to each feeding group were 8.86 in the bottle feeding group, 7.51 in the breast feeding group and 6.77 in the mixed feeding group. 3) The group in which the weaning period was late showed a significantly high dft index. 4) The dft index of the group taking beverages containing sugar before going to bed was significantly higher than that of the group without doing this. 5) The group of patients aged 2 years to 5 years who had between-meal snacks more frequently showed a high dft index. 6) The irregularity of the between-meal eating times caused a high tendency toward caries occurrence. 7) The group having between-meal snacks while playing showed a significantly higher dft index than that of the group having it at a table and not playing. 8) No relation was observed between the frequency of tooth brushing and the dft index.

[Influence on de- and remineralization of dental enamel by toothbrushing with a dental salt].

In the study in question, tests were made to determine whether a dental salt, with or without the addition of fluoride, can improve the remineralization effect of the saliva. The experiments were performed in vitro by applying a method in which the dental enamel was softened and rehardened several times within a short period. The Knoop hardness of the enamel surface was used to determine the degree of de- and remineralization. The results clearly confirm the remineralization-promoting effect of the fluoride added to the dental salt.
