Dear Editor, We read with interest the randomised clinical trial report by Hesse et al.1 concerning low-cost glass ionomer cement as ART sealant in permanent molars. In their Discussion, the authors state “... the choice of considering only fully retained sealants as successful is supported by the current theory that the complete clinical retention of sealant materials should be contemplated as...

Background. Wear resistance of pit and fissure sealant materials can influence their retention. Wear characteristics of sealant materials may determine scheduling of check-up visits. The aim of this study was to compare wear resistance of two flowable composite resins with that of posterior composite resin materials. Methods. Thirty-five disk-shaped specimens were prepared in 5 groups, includin...

This article reviews the scientific literature regarding pit and fissure sealants for oral health care professionals interested in managing dental caries. Review topics include the development of sealant materials; their efficacy and use with incipient caries; the use of sealants in combination with restorative materials and orthodontic care; the utilization patterns of sealants; and profession...

Objective: This in-vitro study evaluated the remineralizing effect of nano-pearl and nano-seashell incorporated into fluoride-based pits-and-fissures sealants by assessing enamel surface microhardness elemental analysis. Materials Methods: 75 extracted third molars were randomly allocated to one following 5 groups fluoride containing sealant: 10% nano-pearl; 15% nano-seashell; or plain sealant....

The penetration coefficients (PCs) and tensile bond strengths of eight pit and fissure sealant materials were determined. The PCs were tested at 22°C with five samples of each resin. Bond strengths were established in a tensile mode using an Instron * testing machine with 10 specimens for each sealant. Despite considerable variation in the PC values, all sealants showed similar tensile bond str...

Introduction: Fissure sealants have been widely used for more than four decades in preventing dental caries. Advances in technology have led to the development of moisture tolerant sealants. They are available as resin based and glass ionomer based. There is a paucity of studies on the effectiveness of moisture tolerant sealant materials in clinical conditions. AIM: The aim of the present study...

objective: adequate knowledge about restorative materials particularly flowable composite resins with favorable physical properties like optimal microhardness and resistance to environmental factors is a big concern for many dentists. flowable composites have several applications for fissure sealant therapy and preventive resin restorations (prr) which are common treatments in pediatric dentist...

Objective: To assess a multiple emission peak light-emitting-diode (LED) light-curing unit (LCU) by measuring the polymerization efficiency through the degree of conversion (DC) and Knoop microhardness (KH) of a resin-based pit and fissure sealant at various light curing times and two distances compared to a single emission peak LED LCU. Method: Sixty disks of a resin-based pit and fissure seal...

OBJECTIVES It is recommended that fissure sealants should be placed within four years after eruption. Due to considerable variations in the eruption times of molar teeth, this recommendation is of limited value from a public health perspective. This study, therefore, sought to provide empirical support for a public health fissure sealant placement timeframe protocol. METHODS The first and sec...

AIM AND OBJECTIVES Fissure caries is most common in children due to deep pit and fissures. Pit and fissure areas on the occlusal surface of the teeth make them susceptible to dental caries, which need to be prevented or restored. Fissures sealant reduces the risk of occlusal caries. The present study was done to evaluate microleakage and shear bond strength of various fissure sealants. MATERI...
