Aims and Objectives: The aim of this study was to assess the mean overjet in school-going Libyan children and to examine the relationship between increased overjet and permanent incisor's trauma., Materials and Methods: This study is a part of a cross-sectional investigation of aspects of dental health of 2015 school going Libyan children aged between 6 and 16 years old of both genders from both rural and urban areas. Overjet was measured as the horizontal distance in millimetres between the upper and lower incisors. Trauma to permanent incisors was assessed according to Elli's Classification., Results: SPSS version 20.0 for percentages was used for statistical analysis. The relationship between increased overjet and incisor trauma was tested using the Chi-square test at 0.05 significance level. The overjet measurement ranged from -2 mm to 8 mm with the mean overjet of 3.062 (1.23, SD). The prevalence of incisor trauma was statistically significantly higher in children with increased overjet (P < 0.0001)., Conclusion: The average mean overjet value in Libyan children is between 2 mm and 3 mm and below or above these values, considered decreased or increased, respectively. Traumatic injuries to permanent incisors significantly increased with increased overjet., Competing Interests: None

Aims and Objectives: The aims of this study were to evaluate the presence of Staphylococcus aureus and Escherichia coli , in polyglycolic acid (PGA) 4-0 and silk sutures, with or without hyaluronic acid (HA) treatment., Materials and Methods: This in vitro study measured S. aureus and E. coli growth on PGA and silk sutures, through incubation in agar media for 24 h. The suture length was 10 cm and divided into three parts: A (8 h), B (16 h), and C (24 h), which were observed every 8 h, followed by suspension on a microscopic slide. This was repeated thrice. The number of S. aureus and E. coli cells was recorded and compared between the suture types., Results: The mean S. aureus colony forming units (CFUs) differed at each time point between non-HA and HA-PGA sutures ( P = 0.0016), with a greater number of CFUs on non-HA-PGA. The mean S. aureus CFUs were significantly higher on non-HA silk than on HA-silk sutures ( P = 0.008). There was a significant increase in E. coli CFUs on non-HA silk than on HA-silk sutures ( P = 0.008). E. coli CFUs were higher on non-HA-PGA than on HA-PGA sutures ( P = 0.006). We performed repeated measures two-way ANOVA (SPSS version 13.0) for comparison between group factors and time points and Posthoc analysis using independent samples t -test., Conclusions: HA reduced wicking in both PGA and silk sutures., Competing Interests: There are no conflicts of interest.
