INTRODUCTION Optimal pit and fissure sealing is determined by surface preparation techniques and choice of materials. The performance of pit and fissure sealant materials has been intensively investigated, yet no single product is reported as an ideal sealant. In children, moisture control during cavity preparation is always a big challenge, and hence, hydrophilic sealants have been developed. ...

Introduction: It was to compare the efficacy of semiannually fluoride varnish application versus pit and fissure sealant to reduce occlusal caries incidence. Materials and methods: A randomized parallel designed study was conducted with 352 child-ren aged 6-7 years. Participants were allocated into biannual application of varnish (n=179) (NaF 5 %( Durafluor, DENTSPLY®, Latin America) or re...

For this literature review of pit and fissure sealant, 1,465 references were selected by a search for “sealants” on PubMed. References were limited to dental journals and papers in the English language. The search comprised papers from 1971 to October 2001. Additional papers of historical significance prior to 1971 were added from memory and from reference lists published in early papers. This ...

PURPOSE The purpose of this clinical trial was to test the use of a primer and bonding agent to increase the retention of a fissuresealant in a group of Kuwaiti children. METHODS In 78 6- to 9-year-old children who required sealants in all 4 permanent frst molars, sealants were placed in 2 teeth using a primer and bond (3M Scotch Bond) and in 2 teeth without primer and bond. Sealant retention...

INTRODUCTION Adhesions to mesh/tacks in laparoscopic ventral hernia repair are often cited as reasons not to adopt its evidence-based superiority over conventional open methods. This pilot study assessed the occurrence of adhesions to full-sized Polypropylene and Gore-tex DualMesh Plus meshes and the possibility for adhesion prevention using fibrin sealant. METHODS Two 10-cm to 15-cm pieces ...

The in vitro accelerated aging of conventional and microfilled composite restorative materials and a sealant was studied. Volume loss/surface area ranged from 2.0 x 10(-3) mm3/mm2 for I to 7.3 x 10(-3) mm3/mm2 for SF after 900 h of aging. Surface morphology of the conventional composites was characterized by crazing and exposure of filler particles. The surfaces of the microfilled composites al...

PURPOSE The purpose of the study was to evaluate the postoperative sensitivity of posterior Class I composite restoration at short-term, restorated with two different all-in-one self-etch adhesives with or without surface sealant application. MATERIALS AND METHODS 44 restorations were inserted in 11 patients who required Class I restorations in their molars. Each patient received 4 restoratio...

F or adequate sealant retention, the bonding surface area must be maximized and the enamel clean, free of salivary contamination, and dry at the time of sealant placement.I, 2 However, because pit and fissure sealants bond to the cuspal incline planes and not to the bottoms of the pits and fissures,B_6 insufficient curing of the resin sealant could reduce the bond strength. The purpose of this ...

The purpose of this study is to compare the marginal leakage of two aesthetic cervical restorative materials viz the newly introduced light cured nano glass ionomer cement and nano ceramic composites, and also to evaluate the effect of unfilled resin sealant coating on marginal leakage of these aesthetic restorations. Thirty freshly extracted human upper premolars were used for the study. Class...
