Association between perceived stress, fear and anxiety of COVID 19 with self-care in pregnant women: a cross-sectional study.

Pandemic COVID-19 has negative effects on the mental health of all people, especially pregnant women. This study aimed to determine the psychological effects of COVID-19 on self-care in pregnant women. The Cross-sectional study using the Multistage sampling technique was conducted among 215 pregnant women selected randomly from the Iranian Integrated Health System in 2020.

The effect of Rosa (L. Rosa canina) on the incidence of urinary tract infection in the puerperium: A randomized placebo-controlled trial.

Urinary tract infection (UTI) is an infection that can occur in any area of the urinary tract which is characterized by a positive urine culture (U/C). The risk of UTI following cesarean section (CS) increases due to procedures such as catheterization. In vitro studies have demonstrated the effect of Rosa canina fruit in preventing Escherichia coli growth.

Effect of Polyvinyl Siloxane Viscosity on Accuracy of Dental Implant Impressions.

Objectives: The aim of this study was to compare the accuracy of dental implant impressions obtained by a combination of different impression techniques and viscosities of polyvinyl siloxane (PVS).

Materials And Methods: Four parallel fixtures were placed between mental foramina in a master model of lower dental arch. Three different viscosities (putty/light body, medium body/light body, and monophase: heavy body) and direct and indirect techniques (six groups) were used, and seven impressions were obtained from each group (n=42).

Comparing the Electromyographic Features of the Masseter and Temporal Muscles in Patients with full Mouth Implant-supported FDPs and Natural Dentition.

Background: Due to increasing demands for a full mouth implant reconstructions and the fact that the most failures are associated with biomechanical complications, determining the effect of different occlusal patterns on these complications seems inevitable. The aim of this study is to compare affection of different occlusal designs in full mouth implant reconstructed patients on electromyographic activity of temporal and masseter muscles compared to natural dentition.

Methods: Thirty-two patients were included in this study, considering that 16 patients had natural dentition and the other 16 were full mouth implant reconstruction patients.
