Objectives: To analyze the ion exchange between conventional glass-ionomer restorative material, (Fuji IX-GC Co., Japan) and tooth components in primary molars after long periods of function in vivo. Methods: Five deciduous mandibular molars were collected after normal exfoliation. An intact deciduous molar served as control, a second deciduous molar was restored occlusaly with Fuji IX in vitro, and 3 deciduous molars with occlusal restorations were collected after 18, 24, and 48 months in vivo. The molars were sectioned bucco-lingual through the restoration and the chemical analysis was performed on enamel, dentin and restorative material along parallel lines crossing from buccal to lingual, using an energy dispersive X-ray spectrometer (EDS). The data was analyzed using SPSS program. Results: In the enamel adjacent to the glass-ionomer material, calcium and phosphate showed a significant reduction related to time (P<0.05). In both enamel and dentin strontium, silica and alumina migrated from the glass-ionomer material in significant concentrations (P<0.05), and fluorine showed an increase from zero in the intact deciduous molar to 1.2% after four years in vivo. In the glass-ionomer material fluorine was reduced in relation with time in vivo, while calcium concentration increased. Conclusions: There is a constant exchange of ions between glass-ionomer restorative material and tooth components in deciduous molars. It begins as early as two weeks in vitro and is increased in vivo. Strontium, alumina and fluorine released from the glassionomer have a bactericidal effect and may affect remineralization. Calcium may enhance the glass-ionomer mineralization and transform it into enamel like material. Clinical significance: The results showed that a continuous exchange of ions between enamel and dentin and glass-ionomer material occurs in vivo and the concentration of the ions is time related. Strontium, alumina and fluorine in enamel and dentin may cause a continuous anti bacterial and anti cariogenic effect, while calcium enhance mineralization of glass-ionomer in vivo, a factor that may increase the longevity of the restoration.

“…Silva et al (20) also highlighted the action of Vidrion R and its importance in clinical studies that confirm in vitro findings to establish the real efficacy of these materials under different conditions present in the oral cavity. As mentioned in the literature (19,20), it was observed that Vidrion R, used for sealing of carious cavities after mass excavation, contribute for reducing the numbers of cariogenic microorganisms due to its antimicrobial properties. Moreover, it is a low-cost material that can be easily purchase by public health services.…”

“…Using the agar diffusion test, Da Silva et al (19) evaluated the antimicrobial effect of glass ionomer cements against S. mutans, S. sobrinus, L. acidophilus and A. viscosus. The authors concluded that fresh and set Vidrion R presents in vitro antimicrobial activity and releases higher concentrations of fluoride, which can influence the antibacterial activity observed.…”

The aim of this study was to determine the effect of oral environment stabilization (OES) on the counting of Streptococcus mutans in high-caries-risk pregnant women participants of a prevention program in a public teaching institution. The sample was composed of 30 pregnant women aged 18 to 43 years, who looked for treatment at the Preventive Dentistry Clinic of the Araraquara Dental School, UNESP. Saliva samples were collected before and after the OES procedures and were forwarded to the pathology for observation and quantification of S. mutans CFU. There was a decrease in the number of S. mutans CFU, which was significantly different (p<0.0001) between samples. Considering the age group, 70.0% were between 18 to 30 years old and 30.0% belonged to the 31-43-year-old age group. Data related to the pregnancy period showed that 73.4% were in the second trimester, 13.3% in the first and 13.3% in third trimester. OES showed to be an effective clinical procedure in diminishing the number of S. mutans CFU in the saliva of high-caries-risk pregnant women. This management is simple and effective, corresponding to the basic treatment needs of pregnant women that search dental care in this public service.

“…The atraumatic restorative treatment (ART) approach consisted in the removal of infected dentin using cutting hand tools under relative isolation followed by the restoration of the cavities with conventional glass ionomer cements (GICs) as the material of choice [1][2][3][4][5][6] . This procedure is considered of low cost, easy handling and high applicability [1][2][3][5][6][7] , which causes minimal discomfort to the patient by eliminating the need for local anesthesia 2,3,5 .…”

Aims:To evaluate the effect of the chlorhexidine (CHX) incorporation and the storage time on the mechanical properties of glass ionomer cements (GICs). Methods: The following GICs were evaluated: Ketac Molar Easymix (KM), Vidrion R (VR) and Vitromolar (VM), containing or not CHX. GIC liquid was modified by adding 1.25 % CHX digluconate and then manipulated with the power and placed into the stainless steel cylindrical or bar-shaped molds. GICs specimens were stored into water for 1, 7 and 28 days. After these periods, specimens were submitted to flexural, diametral tensile and compressive strength tests, according to ISO standards. Data from mechanical tests were statistically analyzed using 2-way ANOVA and Tukey tests. Results: Overall, the storage time did not influence any of the mechanical properties of the GICs tested. In contrast, the inclusion of CHX reduced significantly these properties for all GICs tested. KM presented the highest values of compressive strength for all storage times. KM + 1.25% CHX had lower compressive strength results than KM, however, it showed similar results when compared to another GICs without CHX. Conclusions: The presence of chlorhexidine, independent of the storage time, interfered on the mechanical characteristics of GIC.
