Abstract
Introduction: Research has shown that cons-umption of calcium and iron supplements during pregnancy can prevent some problems in mother and embryo. The aim of this study was to dete-rmine the correlation between consumption of calcium, iron and multivitamin supplements and dental status in post partum mothers.
Materials & Method: This research was a cross-sectional analytical-descriptive study with cluster sampling. The study sample included 150 pregn-ant women in their end phase of pregnancy from Shahid Mostafa Khomini and Hazrate Zeinab hospitals in Tehran. The study was completed from November 2010 to April 2011. Data were collected in 24 to 72 hours post partum. Dem-ographic and supplements consumption data were recorded in a prepared checklist. The numbers of decayed, Missed and Filled teeth (DMFT index) were registered in the post partum. To analyze the data, Spearman correlation coefficient and Linear variance statistical tests were used.
Findings: The correlation between consumption
of iron supplement and DMFT was significant (P<0.001). A direct relationship was found bet-ween the consumption of iron supplement with DMFT (r=-0.33). The correlation between the consumption of calcium supplement and DMFT was significant (P<0.001). An indirect relation-ship was found between the consumption of calci-um supplement with DMFT (r=0.42). The correla-tion between the consumption of multivitamin supplement and DMFT was not significant (P=0.09). There was not a direct relationship bet-ween the consumption of multivitamin supple-ment with DMFT (r=0.18).
Discussion & Conclusion: Consumption of calciu-m supplement during pregnancy keeps teeth heal-thy. Therefore consumption of calcium suppleme-nt during pregnancy is recommended for presser-veng mothers’dental health status.

Abstract
Introduction: There are different species of bacteria in different parts of oral c-avity that cause the tooth decay and pe-riodontal diseases. Pistacia lentiscus L. has been used for gingival problems, to-othache and aromatizing the mouth in Iranian traditional medicine. The aim of this study was evaluating the antibac-terial effect of Pistacia lentiscus L. on Staphylococcus aureus, Streptococcus mutans, Streptococcus sanguis and Ps-eudomonas aeruginosa. Materials & Methods: Methanolic ex-tract of Pistacia lentiscus L. from 100 to1000 mg/ml dilution were examined on strains of Staphylococcus aureus (ATCC25923), Streptococcus mutans( ATCC1601), Streptococcus sanguinis (ATCC1449) and Pseudomonas aerugi-nosa (ATCC25923 ). The well assay an-d disc diffusion methods were applied for testing the antibacterial activity of Pistacia lentiscus L. The Minimum Inh-ibitory Concentration (MIC) and Min-imum Bactericidal Concentration (MB-C) were detected. Findings: The Streptococcus mutans an-d Pseudomonas aeruginosa were not se-nsitive to Pistacia lentiscus L. Staphyl-ococcus aureus and Streptococcus sang-uinis were sensitive at 50, 100 and 1000 mg/ml concentrations. With disk diff-usion method, sensation to Pistacia lent-iscus L. was only showed at 100 mg/ml concentration for Streptococcus sangu-inis that produced an inhibition zone with 17 mm diameter. The MIC of Pist-acia lentiscus L. for Streptococcus sang-uinis was 1000 mg/ml. The other bacte-ria grew in all concentrations. Discussion & Conclusion: The meth-anolic extract of Pistacia lentiscus L. in some concentrations has antibacterial effect on Staphylococcus aureus and St-reptococcus sanguinis, but it doesn´t have any antibacterial effect on strept-ococcus mutans and Pseudomonas aeru-ginosa.
