Anemia is a very frequent event among pregnant women. There are evidences of differences in the incidence of dental caries between pregnant and nonpregnant women, but the relationship between salivary iron (Fe) and serummarkers of anemia and caries development has not been investigated.
To evaluate the correlation between salivary (Fe) and serum iron (Fe, ferritin and hemoglobin) parameters in pregnant women with the development of dental caries.
A prospective cohort was conducted with 59 women. The outcome of interest was represented by new dental caries lesions during pregnancy, using the Nyvad criteria. Pregnant women were evaluated at three clinical times: up to the 16th week of gestational age (GA) (T1), in the last trimester of pregnancy (T2), and postpartum (T3), at the Mother and Child Unit ofUniversityHospital of the Universidade Federal doMaranhão.A stimulated saliva sample was collected for biochemical analysis of salivary Fe, and a blood sample was collected early in the morning. The correlation between salivary and serum Fe was evaluated through the Pearson correlation test. Analysis of variance (ANOVA) and Kruskal-Wallis were used to compare the means of anemia parameters at different times. The Student's t and Mann-Whitney tests were used to compare the anemia parameters between the groups of pregnant women (with and without new caries lesions).
SerumFe concentrationswere higher in the first trimester of pregnancy and lower after delivery (p = 0.036). It was also observed that the ferritin concentrations were higher in the first trimester and lower at the end of gestation (p = 0.011). Therewas no association between the expositions of salivary iron and anemia, and the development of dental caries. There was a positive correlation between serum Fe in T1 and salivary Fe in T2 (p < 0.05).
The serummarkers of anemiaweremore prevalent in the last trimester of pregnancy.

PURPOSE: to verify the association of osteoporosis with periodontal disease. METHODS: the study has included 39 postmenopausal women divided in three groups according to bone mass categories, through evaluation of mineral bone density (MBD), measured by X-ray double emission absorbimetry in the lumbar area (L1-L4): ): normal bone; osteopenia and osteoporosis. In all the participants the Clinical Insertion Level (CIL) index has been determined at the research onset and after one year, by the same examiner. The periodontal situation data have been submitted to statistical analysis with the paired t-Student test. RESULTS: the periodontal exam has shown that postmenopausal women in the osteopenia presented lower CIL at the initial periodontal clinical exam (2.1±1.1 mm), while the ones in the normal bone showed less teeth support tissue loss after one year (3.1±1.6 mm). The statistical analysis has shown that there was no significant difference for the periodontal situation in the normal bone, but there was significant statistical difference for the osteopenia and osteoporosis patients, when CIL values from both evaluation periods were compared. CONCLUSIONS: it is concluded that postmenopausal osteoporosis may be a possible risk factor for periodontal disease.

PURPOSE: to evaluate periodontal conditions and need for treatment supplied by Periodontal Screening and Recording (PSR) in mothers, in order to clarify the relationship between periodontal disease and low birth weight premature newborns. METHODS: PSR was used in a sample of 40 mothers, divided into: test group, consisting of mothers of premature newborns with weight less than 2,500 g (n=20), and the control group, consisting of mothers of term newborns with a weight equal to or over 2,500 g (n=20). The collected data were analyzed by descriptive statistics, and the results of PSR were submitted to statistical analysis in order to verify differences in periodontal condition and need for treatment of the mothers, using the Kolmogorov-Smirnov test, with a significance level of 5%. RESULTS: the presence of periodontal pocket of 3.5 to 5.5 mm was the most common finding among the mothers of newborns with low weight (39.2% of the cases), while the presence of bleeding at probing and absence of a periodontal pocket were the most frequent findings among the mothers of newborns with normal weight (37.5% of the cases). There was a statistically significant difference between periodontal conditions of the mothers of the groups (p=0.0494), but in relation to the need for treatment, there was no significant difference between the studied groups (p>0.05). CONCLUSION: the mothers of preterm newborns with low weight presented worse periodontal conditions, suggesting that periodontal infection may be related to preterm low birth weight newborns.
