A comparative study was made of two alternative methods for the clinical trea tmen t of occlusal pits and fissures in the early post-eruption state. Contralateral pairs of permanent first and second molars wore carefully selected so that one mo/ar couM be given a preventive treatment with pit and fissure soal~n t, while the paired molar surfaces were restored with amalgam.

OBJECTIVES Wear simulations may provide an indication of the clinical performance of pit-and-fissure sealants when associated with primary teeth as counterbody, restricting the involved variables. The aim of this study was to evaluate wear of dental materials used as pit-and-fissure sealants in contact with primary teeth. MATERIALS AND METHODS A resinous sealant (Fluroshield(®)) and a resin-m...

The aim of this study was to evaluate in vitro the marginal microleakage of two glass ionomer materials used as pit and fissure sealants. Thirty healthy premolars extracted for orthodontic treatment were randomly assigned to two groups (n=15) and respectively sealed with two glass ionomers (Group I, Fuji VII and Group II, Fuji IX). All teeth were preserved in artificial saliva (NAF) for 10 days...

Nanotechnology is gaining tremendous impetus due to its capability of modulating matter at smaller and smaller level which drastically changes the chemical, physical and mechanical properties of materials. Nanoparticles have been introduced into oral health care products with good potential to be extensively used for various dental applications. The purpose of this review is to highlight recent...

In recent years, resin-based fluoridated sealants have been introduced, the fluoride intended as a cariespreventive ingredient. Studies of prophylaxis pastes containing glycerine or fluoride that attribute poor retention to an impervious layer produced by the fluoride and other ingredients 1, 2 have been discounted by Bogert and Garcia-Godoy3 and Koch et al. 4 using newer generations of bonding...

Dental caries in young children remains a public health problem particularly for children whose families are socioeconomically deprived. A child's first dental visit should be at approximately 12 months of age and this should facilitate the provision of anticipatory guidance concerning oral health and dental development to the child's parents/guardians. Compliance with dietary advice is of key ...

INTRODUCTION The aims of this study were to assess the prevalence of dental caries and the DMFT index, as well as the distribution pattern of pit and fissure sealants on permanent teeth in a Portuguese sample of adolescents, and to assess whether the existing usage of sealants and socio-demographic factors are correlated to caries prevalence on the examined sample. MATERIALS AND METHODS A cro...

Introduction: The aims of this study were to assess the prevalence of dental caries and the DMFT index, as well as the distribution pattern of pit and fissure sealants on permanent teeth in a Portuguese sample of adolescents, and to assess whether the existing usage of sealants and socio-demographic factors are correlated to caries prevalence on the examined sample. Materials and Methods: A cro...

PURPOSE Sealants form a physical barrier between the oral environment and deep fissures that contribute to caries prevention. It is postulated that sealants possessing antibacterial properties are advantageous. The purpose of this study was to evaluate the antibacterial properties of four pit and fissure sealants using direct contact test (DCT) and agar diffusion test (ADT). METHODS For the D...
