Abstract
Background and objectives: The association of oral micro-organisms with infectious diseases such as bacterial endocarditis is a concern in dentistry. Bacterial endocarditis is a serious disease with a mortality rate of 40%. The present study was conducted to investigate the effect of using chlorhexidine mouthwash on concentrations of some groups of bacteria in gingival sulcus, which is the main contact point of oral flora with circulating blood during scaling.
Methods: In this Randomized controlled clinical trial, participants were selected among referrals to the department of gingival diseases of Yazd dental school. Participants underwent determining plaque index and after scaling, sampling of the buccal and lingual gingival groove of mandibular central and lateral teeth was performed by paper with walking movement.
Results: participants were 53 patients who divided into two groups. Group A consisted of 27 patients (15 women and 12 men) ranging in age from 21 to 54 years mean of 35) who used 50 mL chlorhexidine mouthwash and Group B consisted of 26 patients (13 females and 13 males) ranging in age from 19 to 51 years old with a mean of 35.76 who used 50 mL normal saline before scaling. Study groups were not significantly different in terms of age, sex and plaque index. (P-values= 0.755, 0.348 and 0.708)
Mann Whitney-Wilcoxon test compared the counted values of Streptococcus viridance and Staphylococcus aureus in control group was significantly higher than the study group. (P-value = 0.000)
Conclusion: according to the results of our study chlorhexidine mouthwash prior to scaling teeth significantly reduced Streptococcus viridance and Staphylococcus aureus colony counts and could be recommended as a complementary agent for antibiotic prophylaxis in high risk patients prone to endocarditis, or as the only agent in moderate risk cardiac patients that antibiotic prophylaxis does not been used.

Abstract
Background and Objective: Children’s dental fear is one of the most important challenges that pediatric dentistry faces. Several factors play an important role in children’s dental fear. Home quarantine, changes in routine life and economic disadvantages have resulted in emotional changes in parents and children during COVID-19 pandemic. The aim of this study is to evaluate the levels of children’s dental fear, parental anxiety and their possible correlation during the COVID-19 pandemic.
Material and Methods: The present cross-sectional study comprised one hundred and four children aged 6-12-year-old and their parents. The level of parental anxiety was evaluated using Spielberger state-trait anxiety inventory. CFSS-DS (Children Fear Schedule Survey-Dental Subscale) questionnaire assessed the child’s dental fear. Independent t-test, ANOVA and Pearson correlation coefficient were used for data analysis.
Results: There were significant correlations between the level of parent’s state and trait anxiety and child’s dental fear (respectively P value=0.009 and P value=0.000). However girls showed insignificant higher levels of dental fear compared with boys (P value=0.175), children younger than 9 years old and children with a previous dental treatment had significantly higher dental fear scores (respectively P value=0.006 and P value=0.002). Age, gender and level of education did not show a significant effect on the level of parental anxiety (respectively P value=0.630, P value=0.874 and P value=0.198).
Conclusion: The study has resulted in a significant correlation between parental state-trait anxiety and children’s dental fear.
