Abstract
The purpose of modern dental medicine is to prevent dental caries and promote minimally invasive techniques at the expense of invasive methods. Dental sealants are largely recommended for occlusal surfaces protection, but concerns are related about microleakage at material-enamel interface. This in vitro study aimed to investigate the association between chemical structure, sealing capacity and marginal infiltration for 2 fluoride F containing commercially available resin-based sealants: Pit&Fissure� Sealant (DMP) and Fissurit FX� (Voco) in order to achieve a better description and ensure adequate material selection in every day practice. An optimal resin-based sealant should mimic the structural, physical and mechanical characteristics of enamel. The main difference between the sealing materials tested is based on the amounts of inorganic filler and on the various shapes of the particles in the filler. Pit&Fisure� Sealant express less attachment at enamel interface, higher sorption and greater water solubility, when compared to Fissurit FX�. The better sealing capacity of Fissurit FX� can be described by the homogeneity of the material and the very small size of the inorganic fillers. Dental materials properties used as pit and fissure sealants are sensitive to mechanical, thermic and chemical stress from oral cavity. Regular dental check-up can detect the presence and integrity of sealant and ensure preventive effect in time.
Highlights
Access to modern sources of information, concern for an adequate general health as well as promotion of oral and dental health with particular references to dental aesthetics, have led to a higher demand from patients and increase the acceptability of the decay prophylactic methods, especially pit and fissures sealants.During childhood, in order to reduce caries risk, appropriate diet, hygiene and use of fluoride are recommended as an integrative part for individual oral health
The aim of this in vitro study was to investigate the association between chemical structure, sealing capacity, water sorption and solubility, for 2 fluoride F containing commercially available resin-based sealants: Pit&Fissure® Sealant (DMP) and Fissurit FX®(Voco)
The chemical compounds make the difference between the materials
Summary
Access to modern sources of information, concern for an adequate general health as well as promotion of oral and dental health with particular references to dental aesthetics, have led to a higher demand from patients and increase the acceptability of the decay prophylactic methods, especially pit and fissures sealants. The active involvement and patient compliance in respect of dental caries preventive algorithm are difficult factors to quantify especially for children’s, which is why dental sealants must benefit from a proper characterization using in vivo and in vitro studies. The aim of this in vitro study was to investigate the association between chemical structure, sealing capacity, water sorption and solubility, for 2 fluoride F containing commercially available resin-based sealants: Pit&Fissure® Sealant (DMP) and Fissurit FX®(Voco)
