Three‐Year Clinical Evaluation of a Silorane Composite Resin

Abstract

The silorane-based composite resin Filtek LS and the conventional methacrylate-based composite resin Tetric EvoCeram performed similarly well in posterior restorations over at least 36 months of clinical service.

The use of FDI criteria in clinical trials on direct dental restorations: A scoping review

“…Figure 3 showed the percentage of use for each criterion in the 30 selected studies. Only two studies used all the 16 existing FDI criteria [35,37]. The average number of criteria chosen in all studies was 8.5.…”

“…The most employed criteria were: marginal adaptation (criterion 6; 29 studies, i.e. 96.7% of the studies) [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][26][27][28][29][30][31][32][33][34][35][36][37][38], staining (criterion 2; 27 studies, i.e. 90.0% of the studies) [9-18, 20-23, 25-30, 32-38], fracture of material and retention (criterion 5;…”

“…60.0% of the studies) [9, 10, 12-14, 16, 18, 20-24, 29, 32, 34-37]. The least used criteria were: radiographic examination (criterion 9; 6 studies) [10,11,18,34,35,37], patient's view (criterion 10; 7 studies) [12,20,24,[34][35][36][37] and oral and general health (criteria 16, 9 studies) [10,12,16,18,20,31,34,35,37].…”

“…All the studies analysed adhesive materials. Most of them investigated the performance of composite resins (flowable or not, silorane) [16,23,37] and/or the procedures i.e with chlorhexidine pre-treatment [32], with or without bevel [13,14], with rubber dam or cotton rolls/retraction cord [26], with various polishing systems [21] and/or the indications (for non-carious cervical lesion, for primary teeth, in anterior or posterior position) [9-11, 18, 20, 31, 34-36]. Many other studies evaluated the performance of various adhesive types (etch and rinse, self-etch or universal) [27,30,33] and/or the procedure (with EDTA conditioning) [28] and/or the indications (for non-carious cervical lesions) [12,15,17,38].…”

Polymerization shrinkage stress of composite resins and resin cements – What do we need to know?

“…32 This evidences the complexity of this subject, and helps partially explain why to date no clinical evidence exists that low-shrinking materials perform significantly better than conventional ones in terms of improving restoration longevity. 77,78,79 In the clinical situation, the presence of biofilm and the vast variation in patient's hygiene and dietary habits complicates matters even further. Indeed, even though the correlation between polymerization stress and gap formation has been well established, 80 no clinical studies exist demonstrating such correlation in vivo.…”
