The allergy preventive eVect of extensively (N) and partially (PH) hydrolysed cows' milk formulas compared with a regular formula (RM) was assessed in 155 infants with a family history of allergy. No cows' milk was given during the first nine months of life and no egg and fish up to 12 months of age. Breast feeding mothers avoided the same foods. At weaning the infants were randomised to one of the formula groups. The cumulative incidence of atopic symptoms at 18 months was 51, 64, and 84% in the N, PH, and RM groups, respectively. From 6 to 18 months there were significantly less cumulative atopic symptoms in the N group compared with the RM group, and significantly less than the PH group up to 6 (N = 25%; PH = 46%) and 9 months (N = 34%, PH = 58%). At 9 months significantly fewer infants in the N group (10%) than in the PH group (33%) had a positive skin prick test to eggs. The findings support an allergy preventive eVect of an extensively hydrolysed formula, but not of a partially hydrolysed formula, during the first 18 months of life of high risk infants.
The aim of the present case-control study was to investigate dental caries, various caries-related factors as well as gingival condition, in 12- to 16-year-olds with long-term asthma (n = 20) and a matched healthy control group (n = 20). Data on dietary and oral hygiene habits, numbers of mutans streptococci and lactobacilli in saliva were also obtained. The plaque pH drop after a sucrose rinse was measured up to 40 min at 2 approximal tooth sites. A lower salivary flow rate was found in the asthma group compared to the control group (p < 0.05). The mean (± SD) of DFS, including manifest and initial caries, was 4.9 ± 5.5 in the asthma and 1.4 ± 2.3 (p < 0.01) in the control group. Only 1 adolescent in the asthma group was caries free compared to 13 in the control group. Concerning pH in plaque, adolescents with asthma had a lower initial value (p < 0.01) and final pH (p < 0.05) than the control group. The Cariogram data showed that 55% of the subjects in the control group had ‘a high chance of avoiding caries’ compared to 10% in the asthma group (p < 0.01). The asthmatic adolescents had higher numbers of sites with gingival bleeding (p < 0.01). To conclude, adolescents with long-term asthma had a higher total DFS and caries risk (according to Cariogram), decreased salivary rate, more gingival bleeding and lower plaque pH than adolescents without asthma.
Objectives. The aim of the present investigation was to study oral health in young adults with long-term, controlled asthma. Material and methods. Twenty 18-to 24-year-olds with a mean duration (SD) of asthma disease of 13.5 (5.4) years and 20 matched healthy controls were included. A clinical examination was performed and the prevalence of caries, erosions, gingival inflammation, cervicular fluid, periodontal pockets and plaque formation rate, were registered. The salivary flow rate, numbers of mutans streptococci and lactobacilli in saliva were determined. Plaque pH was measured after a sucrose rinse up to 40 min at two approximal sites. The participants were interviewed regarding dietary and oral hygiene habits. Results. The mean (SD) DFS, including manifest and initial caries, was 8.6 (10.6) in the asthma group and 4.0 (5.2) in the control group (p = 0.09). Initial caries lesions were more common in the asthma group than in the control group, 6.0 (8.1) and 1.3 (2.0 (p = 0.02). The asthma group had more gingivitis (p = 0.01) and lower stimulated salivary rate than the controls (p = 0.01). The asthmatics had also a somewhat, but not statistically significant, lower initial pH value in plaque and more pronounced pH drop compared with the controls. In the asthma group, 65% reported frequent mouthbreathing compared with 10% in the controls (p = 0.01). No differences were found in tooth-brushing and dietary habits between the groups. Conclusions. Young adults with long-term, controlled asthma had more initial caries, more gingival inflammation and lower stimulated salivary secretion rate than individuals without asthma.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
