          Abstract

          The aim of this clinical, prospective, randomized, and parallel study was to evaluate different in-office treatments for dentin hypersensitivity (DH). One hundred ninety-two teeth with non-cavitated root exposures were treated using different desensitizers: fluoride varnish (Duraphat - FLU); bioactive ceramic solution (Biosilicate - BIOS); universal self-etching adhesive (Single Bond Universal - SBU); bioactive photoactivated varnish (PRG filler - SPRG). The degree of DH was analyzed using a visual analog scale (VAS) and computerized visual scale (CoVAS), before treatments and after 7, 15, and 30 days from the first session. Comparisons among desensitizers were performed using the Kruskal-Wallis and Dunn's tests. Friedman test was used to compare between times (p ≤ 0.05). Comparing desensitizers FLU presented a higher value of DH than BIOS using VAS at 7 days, however, no differences were found using CoVAS analysis. Comparing times, BIOS and SBU showed a reduction in DH after 7 days and SBU showed a reduction at 30 days compared to 7 days using VAS. FLU and SPRG groups reduced DH from 15 days to 30 days using VAS. There was a reduction in DH for FLU, BIOS, and SBU after 7 days and for BIOS this reduction also occurred at 30 days when compared to 15 days using CoVAS. SPRG group showed a reduction from 15 to 30 days. All desensitizers tested were able to reduce the initial sensitivity. The bioactive ceramic solution reduced the DH gradually after 30 days using computerized analysis.

          Resumo

          O objetivo deste estudo clínico, prospectivo, randomizado e paralelo foi avaliar diferentes tratamentos em consultório para hipersensibilidade dentinária (HD). Cento e noventa e dois dentes com exposições radiculares não cavitadas foram tratados com diferentes dessensibilizantes: verniz fluoretado (Duraphat - FLU); solução cerâmica bioativa (Biosilicato - BIOS); adesivo autocondicionante universal (Single Bond Universal - SBU); verniz fotoativado bioativo (PRG filler - SPRG). O grau de HD foi analisado por meio da escala visual analógica (VAS) e da escala visual computadorizada (CoVAS), antes dos tratamentos e após 7, 15 e 30 dias da primeira sessão. As comparações entre dessensibilizantes foram feitas pelos testes de Kruskal-Wallis e Dunn. O teste de Friedman foi utilizado para comparação entre os tempos (p ≤ 0,05). Comparando os dessensibilizantes, o FLU apresentou um valor de HD maior do que o BIOS usando VAS aos 7 dias, no entanto, nenhuma diferença foi encontrada usando a análise CoVAS. Comparando os tempos, BIOS e SBU apresentaram redução de HD após 7 dias e SBU apresentou redução aos 30 dias em comparação com 7 dias usando VAS. Os grupos FLU e SPRG reduziram a HD em 15 dias a 30 dias usando VAS. Houve redução de HD para FLU, BIOS e SBU após 7 dias e para BIOS essa redução também ocorreu aos 30 dias quando comparada a 15 dias usando CoVAS. O grupo SPRG apresentou redução de 15 para 30 dias. Todos os dessensibilizantes testados foram capazes de reduzir a sensibilidade inicial. A solução de cerâmica bioativa reduziu o HD gradualmente após 30 dias usando análise computadorizada.

            Detection of ions released from S-PRG fillers and their modulation effect.

            The purpose of this study was to analyze the ions released from a surface pre-reacted glass ionomer (S-PRG) filler in distilled water or lactic acid solution. S-PRG filler was mixed with either solution at 1000:1, 100:1, 10:1, and 1:1 ratios by weight. By means of inductively coupled plasma atomic emission spectroscopy and a fluoride electrode, elements released from S-PRG filler were identified to be Al, B, Na, Si, Sr, and F. To investigate the effect of solution pH on ion release, the pH values of the solutions before mixing and after 24 hours' mixing with S-PRG were measured. After 24 hours' mixing, the pH values of solutions at all ratios became more neutral or weakly alkaline regardless of their initial pH levels before mixing. In conclusion, results showed that S-PRG filler released several types of ions, and that ion release was influenced by the mixing ratio of the solution rather than the initial pH of the solution.
