The most common cause of death and mortality of infants is preterm labor. The identification of factors associated with preterm labor will reduce preterm infant mortality. This study aimed to determine the relationship between preterm delivery and oral, kidney and urinary tracts infections in pregnant women

This was a case-control study that carried on the 198 pregnant women (66 pregnant women with premature labor as case group and 132 pregnant women with term delivery as control group) in selected hospitals in Isfahan, Iran, in 2018. For data collection we used demographic and fertility questionnaire, and the Holbrook standard checklist. Data were analyzed using descriptive statistics and t–test, chi-square, Mann-Whitney, Fisher’s exact test, logistic regression.

The results showed that there was no significant relationship between preterm labor and kidney, urinary tracts infections (p=0.626). While the logistic regression showed significant association between the onset of uterine contractions (preterm birth) and of the mouth and teeth infections (p=0.012)

The findings suggest that there is relationship between preterm deliveries and oral infections. Therefore, it is recommended that preventive necessary measures be taken or treat oral infections faster in women before and during pregnancy.

Oral and dental diseases such as dental caries and gingivitis are common problems in human societies. The formation of biofilms is considered as a very important mechanism of disease by these bacteria. The present study is an overview of these infectious diseases and their bacterial etiology, the mechanism of formation and role of dental plaque biofilm in the development of these infections and vaccination against dental caries is a new research field for dealing with these oral-dental diseases. In the current review paper, relevant articles were collected at Science Direct, Google Scholar, and PubMed databases from 1995 to 2017 and reviewed over a period of 2 months. Articles related to the role of bacterial biofilms in oral and dental diseases were used to write this research. As a result of the review of articles, it was seen that bacteria are one of the main causes of oral and etiology infections. Although the formation of bacterial biofilm at the different dental and oral surfaces is not necessarily related to the disease, but the formation of biofilms is considered as a very important mechanism of disease by these bacteria. The dental plaque biofilm in health condition often consists of non-pathogenic bacteria and humans. However, the in pathogenic biofilms, the levels of acidogenic and aciduric bacteria have increased dramatically and, by creating a stable acidic environment, demineralization occurs more rapidly.

Fungal infections, especially candida species, are the most common opportunistic fungal infections and the treatments with chemical drugs have many side effects. Melissa Officinalis has antimicrobial effects that has caused it to be considered in many microbial treatments. In this study, it has been tried to compare this herbal efficacy on Candida Albicans, Candida Glabrata and Candida Krusei.
Aqueous and ethanol extracts of Melissa Officinalis was obtained by drench method. The diameter of non- growing zone of Candida Albicans, Candida Glabrata and Candida Krusei was estimated by the micro dilution method.
The mean diameter of the non-growing zone related to the extracts on Candida Albicans was 17.83 mm (versing 5.75 mm of aqueous extracts) and the mean diameter of the non-growing zone related to aqueous extracts on Candida Glabrata and Candida Krusei were 15.5 and 13.66 mm respectively (versing 10 and 7mm of ethanolic extracts).
All extracts had an effect on non- growing fungal zone, however ethanolic extract of Candida Albicans and aqueous extract of Candida Krusei were more effective rather than the others. Also, there was no difference between the effect of Aqueous and ethanolic extracts in Candida Glabrata.
