  • an in vitro evaluation of the efficacy of a novel iontophoresis Fluoride Tray on remineralization
    Journal of Clinical and Experimental Dentistry, 2014
    Co-Authors: Gonca Girenes, Tezer Ulusu
    Abstract:

    Objectives: The aim of this study is to determine the effects on remineralization of a novel iontophoresis device called ‘Fluorinex’, conventional (acidulated phosphat Fluoride) APF gel treatment, and conventional ionthophoresis device comparatively by laser fluorescence measurements. Study Design: Artificial incipient carious lesions were created on immature, 60 intact premolar and molar teeth with no defects. The specimens were randomly allocated to four groups. In the first group 1.23% APF gel was applied to specimens by conventional method for 4 minutes and in the second group 2% (sodium Fluoride) NaF solution applied by conventional iontophoresis device for 4 minutes. In Fluorinex group specimens were pretreated with (copper chloride) CuCl2 for 1 minute and then treated for 4 minutes with 1.23% APF gel in a FluoriTray. Control group was placed in distilled water for 4 minutes. After these applications all specimens were included to a pH cycling. DIAGNOdent pen measurement were obtained in three different time intervals; after incipient carious lesions, after Fluoride treatments and after pH cycling. Specimens were studied by SEM(scanning electron microscopy) after artificial caries lesions and Fluoride treatments. Results: Alterations on DIAGNOdent pen measurements before and after treatment, the Fluorinex group was statistically different from conventional APF gel (p=0.011), conventional NaF iontophoresis (p<0.001) and control group (p<0.001). As the DIAGNOdent pen measurements before treatment and after pH cycling were compared, differences were statistically significant in Fluorinex and conventional APF gel groups (p<0.001). Conclusions: The results of this in vitro study has shown that Fluoride application by Fluorinex was superior to the conventional APF gel application and NaF iontophoresis on incipient carious lesions. Key words:Fluoride, iontophoresis, remineralization.

  • Recovering Streptococcus mutans over restorations by the Tray technique: a randomized clinical study
    Faculdade de Odontologia de Piracicaba - UNICAMP, 2013
    Co-Authors: Vildósola Grez Patricio, Osmir Batista De ,oliveira, Palma Fluxa Patricia, Zuñiga Saavedra Paula, Fernandez Godoy Eduardo, Moncada Cortés Gustavo
    Abstract:

    AIM: To correlate the Tray technique for isolation and counting of Streptococcus mutans over dental restoration with the toothpick technique. METHODS: Forty 18-50-year-old patients of both genders with high cariogenic risk were selected. Inclusion criteria were: occlusal restoration evaluated as alpha, according to the Ryge's criteria (examiner' Cohen-Kappa 0.8) and 2 years old maximum age. Each patient provided a saliva sample (control group S) and two samples of dental biofilm from amalgam or resin-based composite restorations in the same patient, one obtained with the toothpick technique (group TT), and the other from homologous tooth restoration with the Tray technique (group TR). This method involves only a direct impression on the occlusal surfaces by a section of a Fluoride Tray with trypticase yeast extract cysteine sucrose with bacitracin (TYCSB) agar previously prepared and solidified. The samples were incubated at 37 ºC for 48 h and the colony-forming units (CFU) were counted. The results were statistically analyzed with SPSS software using the linear regression method at 95% confidence level. RESULTS: TR was able to isolate S. mutans, and there was a significant positive correlation (r=0.95) with TT. There was no significant correlation between TR and control group S (r=0.47). CONCLUSIONS: TR was able to isolate and count S. mutans from the dental biofilm of dental restorations with a significant correlation with the TT group.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
