statement of problem: since the fluoride releases from materials with the property of releasing fluoride are decreasing gradually, it seems that probably the material rechargeability is more important than their long-term fluoride release. purpose: the objective of this study was to asses the fluoride release and rechargeability of 2 types of fluoride releasing restorative materials, a resin mo...

AIM The goal of this study was to evaluate nanoleakage within the hybrid layer yielded by etch-and-rinse and self-etch adhesive systems, with different solvents and compositions. MATERIALS AND METHODS Four adhesives were applied onto 20 human dentin disks: group A: Adper Scotchbond 1XT(™) (3M ESPE), group B: One Coat Bond(®) (Coltène Whaledent), group C: AdheSE(®) (Ivoclar Vivadent) and group...

The dental plaque harbours a diverse range of bacteria such as Streptococcus mutans, Streptococcus sanguis, Streptococcus sobrinus, Lactobacillus spp, Actinomyces spp. etc, embedded in a matrix of polymers of bacterial and salivary origin. Therapeutic procedures used in the treatment of caries do not always eliminate all the microorganisms in the residual tissues, leading to development of recu...

UNLABELLED (Full text is available at http://www.manu.edu.mk/prilozi). OBJECTIVES The study was aimed at determining the effectiveness of fluoride-releasing materials (conventional and resin-modified glass-ionomers, compomer and fluoride-releasing composite resin) in inhibiting demineralization of restored teeth in an artificial caries medium. METHODS A total of 72 teeth (36 deciduous and 3...

OBJECTIVE The purposes of this research were to (1) compare the shear-peel bond strength (SPBS) of a band of a fixed space maintainer (SM) cemented with five different adhesive cements; and (2) compare the survival time of bands of SM with each cement type after simulating mechanical fatigue stress. MATERIALS AND METHODS Seventy-five teeth were used to assess retentive strength and another 50...

BACKGROUND Microleakage is one of the most frequently encountered problems in posterior tooth-colored restorations. Efforts to decrease this problem with resin restorations include techniques for reducing the ratio of bonded to unbonded restoration surfaces and following strategic incremental placement techniques to reduce residual stress at tooth-restoration interface which reduces the C-facto...

OBJECTIVE The aim of this study was to evaluate the effect of neutral sodium fluoride (NNaF) gel and acidulated phosphate fluoride (APF) gel on the surface roughness of colored compomer (Twinky Star), conventional compomer (Compoglass F) and resin-modified glass-ionomer cement (RMGIC) (Photac-Fil). MATERIAL AND METHODS A total of 45 standardized disc-shaped specimens were prepared for each ma...

The “reverse” stainless steel crown is a well-known method of correcting single tooth anterior crossbite (Fig 1). When an elongated preformed incisor stainless steel crown is luted with the lingual surface facing labially, the resulting slope contacts the opposing mandibular incisors and normal occlusal forces move the incisors out of crossbite relationship. The reverse crown method corrects “d...
