Coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity: ...
Silva,Karine Letícia da; Sutil,Elisama; Hortkoff,Diego; Terra,Renata Maria Oleniki; Rezende,Márcia; Reis,Alessandra; Loguercio,Alessandro D.Abstract This clinical trial evaluated the effect of the coadministration of ibuprofen/caffeine on bleaching-induced tooth sensitivity (TS). A triple-blind, parallel-design, randomized clinical trial was conducted on 84 patients who received ibuprofen/caffeine or placebo capsules. The drugs were administered for 48 hours, starting 1 hour before the in-office bleaching. Two bleaching sessions were performed with...
Collagen cross-linking agents + dimethyl sulfoxide improving the adhesive prope...
Siqueira,Fabiana Suelen Figueredo de; Szesz,Anna Luiza; Moreira,Pedro Henrique de Aguiar; Araujo,Lucila Cristina Rodrigues; Reis,AlessandraAbstract To investigate the effect of the dimethyl sulfoxide combined with cross-linking agents on microtensile bond strength, silver nitrate penetration and in situ degree of conversion analysis of adhesives to the erosive dentin treatment with Cola-based soft drink. One hundred and sixty-six molars were assigned to 20 groups: (1) Treatment: Sound dentin; Erosive dentin; Erosive dentin treated with primer of d...
Effect of Self-Etching Primer Associated to Hydrofluoric acid or Silane on Bond...
Siqueira,Fabiana Suelen Figuerêdo de; Campos,Veridiana Silva; Wendlinger,Michel; Muso,Rosa Ana Chiluisa; Gomes,João Carlos; Reis,AlessandraAbstract To evaluate the effect of combining 5% hydrofluoric acid (HF) and silane (SI) with the self-etching ceramic primer on the immediate and after 1-year of water storage on bonding efficacy, conditioning pattern (CP) and chemical interaction (CI) to the lithium disilicate. A total of 16 CAD/CAM blocks of lithium disilicate (LD) were cut into four square sections (n=64). For bonding efficacy evaluation, the...
Response of Human Pulps to Different In-Office Bleaching Techniques: Preliminar...
Roderjan,Douglas Augusto; Stanislawczuk,Rodrigo; Hebling,Josimeri; Costa,Carlos Alberto de Souza; Reis,Alessandra; Loguercio,Alessandro D.This study evaluated a whitening effect and the likely side effect (tooth sensitivity and pulp response) of human teeth subjected to different in-office bleaching (IOB) techniques and materials, mainly the presence of calcium in the IOB materials. A calcium-free (CF) and a calcium-containing (CC) 35% hydrogen peroxide (HP) gels were evaluated. The CF was refreshed every 15 minutes, three times (CF 3-15) or in a...
Antioxidant activity by DPPH assay of potential solutions to be applied on blea...
Garcia,Eugenio José; Oldoni,Tatiane Luiza Cadorin; Alencar,Severino Matias de; Reis,Alessandra; Loguercio,Alessandro D.; Grande,Rosa Helena MirandaThe aim of this study was to assess, using the DPPH assay, the antioxidant activity of several substances that could be proposed to immediately revert the problems caused by bleaching procedures. The percentage of antioxidant activity (AA%) of 10% ascorbic acid solution (AAcidS), 10% ascorbic acid gel (AAcidG), 10% sodium ascorbate solution (SodAsS), 10% sodium ascorbate gel (SodAsG), 10% sodium bicarbonate (Bi...
Qualitative SEM/EDS analysis of microleakage and apical gap formation of adhesi...
Souza,Soraia de Fátima Carvalho; Francci,Carlos; Bombana,Antonio C.; Kenshima,Silvia; Barroso,Lúcia P.; D'Agostino,Liz Z.; Loguercio,Alessandro D.OBJECTIVE: The aim of this study was to compare the correspondence between gap formation and apical microleakage in root canals filled with epoxy resin-based (AH Plus) combined or not with resinous primer or with a dimethacrylate-based root canal sealer (Epiphany). MATERIAL AND METHODS: Thirty-nine lower single-rooted human premolars were filled by the lateral condensation technique (LC) and immersed in a 50-wt...
