Our results showed a lack of knowledge of sports participants about management and prevention of traumatic dental injuries. Educational programs should be organized to give information about emergency treatment and promote the use of mouthguards to sport participants.
Education, monitoring, improved availability of resources, and disciplinary measures in cases of poor compliance are necessary to improve TDI management in hospitals, especially among physicians.
Aims: The aim of this study was to evaluate and to compare the effect of two fluoride varnishes and one fluoride/chlorhexidine varnish on Streptococcus mutans and Streptococcus sobrinus biofilm formation, in vitro.Study design: Standard acrylic discs were prepared and divided into groups based on the varnish applied to the disc surface: Fluor Protector, Bifluoride 12, and Fluor Protector + Cervitec (1:1). Untreated discs served as controls. In the study groups, biofilms of S. mutans and S. sobrinus were formed over 24 h, 48 h, and 5 days. The fluoride concentrations in the monospecies biofilms and viable counts of S. mutans and S. sobrinus were investigated.Results: In all study groups, a statistically significant increase in the viable number of S. mutans and S. sobrinus cells was observed between 24 h and 5 days. In both monospecies biofilms, the greatest antibacterial efficacy was detected in the Fluor Protector and Fluor Protector + Cervitec groups at 24 h. For all groups, the amount of fluoride released was highest during the first 24 h, followed by a significant decrease over the next 4 days. A negative correlation was detected between fluoride concentration and antibacterial effect in those groups with biofilms containing both species. Despite the release of high levels of fluoride, the greatest number of viable S. mutans and S. sobrinus cells was detected in the Bifluoride 12 group.Statistics: The data were analyzed using GraphPad Prism software (ver. 3).Conclusions: The Fluor Protector + Cervitec varnish exerted prolonged antibacterial effects on S. mutans and S. sobrinus biofilms compared to the other varnishes tested.
FC and ABS were found successful as pulp dressings in primary molars. ABS appears to be an alternative pulpotomy agent but periodical follow-ups must be considered to evaluate long term success rates.
MTA can be considered as a good choice for a definitive root filling material in horizontal tooth root fractures with excellent biological and physical properties.
The hyper-IgE syndrome (HIES) is a rare disorder characterized by pruritic dermatitis, recurrent Staphylococcus skin abscesses and extremely elevated levels of IgE in serum. In this report, an elevenyear-old-boy with hyper-IgE syndrome is presented. He had a coarse facial appearance, pruritic dermatitis, recurrent skin abscesses, pulmonary infection, a reduced rate of resorption of the roots of primary teeth and an elevated serum IgE concentration. The colonization of Candida albicans, Kiebsiella pneumoniae, Escherichia coli and Staphylococcus aureus were found as; (1x102 CFU), (2.2x104 CFU), (2.2x104 CFU) and (2.6x103 CFU) per ml saliva, respectively. Also the pulp of a deciduous molar was investigated with light and transmission electron microscope (TEM). As conclusion, treatment for this condition is lifelong administration of therapeutic doses of a penicillinase-resistant penicillin, with the addition of other antibiotics or anti-fungal agents as required for specific infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
