This study evaluated the effect of different types of filler in a resin-based pit and fissure sealant on fluoride release, recharge, and lactic acid neutralization. Resin-based sealant was incorporated with 5% w/w of the following fillers: calcium aluminate cement (CAC), synthesized mesoporous silica (SI), a CAC and SI mixture (CAC+SI), glass-ionomer powder (GIC), and acetic acid-treated GIC (G...

This report details a 47 patient, prospective, non-randomized, single-center clinical study to evaluate the safety and performance of a new synthetic dural sealant as an adjunct to standard surgical dural repair techniques to prevent cerebrospinal fluid (CSF) leakage. A consecutive series of patients scheduled for cranial and spinal intradural surgery each received standard dural closures. Afte...

Glass ionomer cement, besides being used as restorative material, can also be used as pit and fissure sealant. The use of glass ionomer cement as pit and fissure sealant has added benefit by its fluoride-releasing property that results in increased resistance of the fissures to demineralize. The capacity of a sealant to prevent microleakage into the fissure is important, since microleakage may ...

controlled by the organic content of the enamel. Marshall, Olson, and Lee4 in 1975 studied acid etching for pit and fissure sealants without precleaning the teeth and found significant advantage in having a clean, debris-free, and uniformly roughened surface for good sealing. They proposed longer etching time. Other studies proposed using other materials to solve this problem of debris. In 1979...

PURPOSE The aim of this study was to determine if flowable composites can be used as pit and fissure sealants without bonding agents. METHODS Three flowable composites (Filtek Flow, Tetric Flow, Charmfil Flow) and a filled sealant (Ultraseal XT Plus) were used. The patterns of resin tag formation in the 4 sealant materials were compared using scanning electron microscopy. For the microleakage...

PURPOSE The purpose of this study was to evaluate the retention rate and the caries increment differences between a light cured, F releasing filled fissure sealant and a non-F nonfilled one. METHODS The two different fissure sealants (Fluoroshield, Delton) were placed on all 4 caries-free first permanent molars of 112 children aged 7-8 years, under a half-mouth experimental design. All the ch...

Objective. To compare four different dry cow treatments (DCT) and establish their effectiveness in reducing intramammary infections (IIM). Materials and methods. DCTs included systemic tylosin (12g) alone or accompanied by cefapirine intramammary infusions and or an internal teat sealant. A total number of 278 cows at the end of lactation period were randomly assigned to one of 4 dry cow treatm...

Bone Joint J 2013;95-B, Supple A:135–9. Received 7 September 2013; Accepted after revision 8 September 2013 Blood loss during total knee replacement (TKR) remains a significant concern. In this study, 114 patients underwent TKR, and were divided into two groups based on whether they received a new generation fibrin sealant intra-operatively, or a local infiltration containing adrenaline. Groups...

OBJECTIVE To compare the retention and the caries preventive effect of a glass-ionomer developed for fissure sealing (Fuji III) and a chemically polymerized resin-based fissure sealant (Delton). DESIGN A split mouth randomized design using contralateral teeth. SETTING WHO Regional Demonstration, Training and Research Center for Oral Health, Damascus, Syrian Arab Republic. SAMPLE AND METHO...
