Introduction. Therapy with fixed orthodontic appliances starts with bracket bonding and ends with debonding of brackets, leaving enamel surface varied. Objective. The aim of this pilot study was to examine enamel surface before and after debonding of orthodontic brackets by the use of scanning electron microscopy (SEM). Methods. Epoxy replicas of four patients? premolars indicated for therapy with fixed orthodontic appliances were made and brackets were bonded to their teeth with a different adhesives (Enlight, No-mix, Fuji Ortho LC and Heliosit Orthodontic) (n=4). Two months later, brackets on premolars were debonded and amounts of adhesive left on the tooth surfaces and the bracket bases were evaluated with the adhesive remnant index (ARI). After resin removal, epoxy replicas were made and the surface of premolars was evaluated with the enamel surface index (ESI). All replicas of premolars (n=32) were prepared for SEM examination and compared under different magnifications. Tooth damage was estimated based on correlation between ARItooth and ESI. Results. Pearson?s ?2 test showed no significant differences between ARItooth and ARIbracket of four materials used. Nonparametric correlations showed significant differences between ARItooth and ARIbracket, ESI and ARItooth, and between ESI and ARIbracket. Increasing of ARItooth is followed with the descent of ARIbracket and the ascent of ESI. Multivariate regression analysis showed a significant correlation between ESI and ARItooth. Conclusion. Most bond failures took place at enamel-adhesive interface. ARItooth was a predictor to enamel surface damage. The type of material did not affect enamel surface damage.

ABSTRACT We previously demonstrated that recombinant protein PAc could be administered as an anticaries vaccine. However, the relatively weak immunogenicity of PAc limits its application. In the present study, we investigated the effect of two adjuvant combinations of chitosan plus Pam3CSK4 (chitosan-Pam3CSK4) and of chitosan plus monophosphoryl lipid A (chitosan-MPL) in the immune responses to the PAc protein in vivo and in vitro. PAc-chitosan-Pam3CSK4 or PAc-chitosan-MPL promoted significantly higher PAc-specific antibody titers in serum and saliva, inhibited Streptococcus mutans colonization onto the tooth surfaces, and endowed better protection effect with significantly less caries activities than PAc alone. Chitosan-Pam3CSK4 and chitosan-MPL showed no statistically significant differences. In conclusion, our study demonstrated that the chitosan-Pam3CSK4 and chitosan-MPL combinations are promising for anticaries vaccine development.

ABSTRACT Introduction The detection of carious lesions in the initial stages of development is very important to prevent the occurrence of cavitation. Visual examination and the use of a dental probe, bite-wing radiography, and fiberoptic transillumination (FOTI) have long been recommended for this purpose. Visual examination and probing of suspected lesions are useful for detecting occlusal caries, but achieve no gain of sensitivity and might cause irreversible tooth damage. Bite-wing radiography helps to detect approximal lesions better than clinical examination and probing the lesion. But the diagnostic performance of bite-wing radiography at approximal and occlusal sites is different. The FOTI is a quick and inexpensive method that can enhance visual examination of all tooth surfaces. The aim of this in vivo study is to compare FOTI with bite-wing radiography and visual examination in the detection of approximal and occlusal caries. Materials and methods A total of 46 patients without missing teeth and dentures in the posterior region of jaws were examined for the evaluation of all premolar and molar teeth contacts. Three blinded practitioners examined the patients. First one evaluated radiologically, second one visually, and the last one evaluated with FOTI. Results According to statistical results, bite-wing radiograph had the highest sensitivity. However, evaluation with FOTI had acceptable results to detect approximal caries. Conclusion Study of the results has shown that clinically FOTI is an adjunct method for detection of approximal caries. How to cite this article Eren H, Yuksel HT, Inceoglu B, Kursun ES, Gorgun S.
