“…Pit and ssure sealants are frequently used to prevent pit and ssure caries and to arrest the incipient caries on the occlusal surfaces by forming a physical barrier [8,9]. Previous research has shown that the effectiveness of pit and ssure sealants in preventing or arresting caries [10,11]. Pit and ssure sealants, on the other hand, cannot be placed to the bottom of pits and ssures, thus resulting in a space underneath the polymerized pit and ssure sealant [12].…”

Objectives. The objective of this study was to develop a resin-based pit and fissure sealant incorporating 45S5 bioactive glass (BAG), which exhibits a self-marginal sealing potential by forming hydroxyapatite, and to assess its chemical properties and apatite formation. Materials and Methods. Experimental materials were prepared by adding 45S5 BAG to the resin matrix at concentrations of 0 (control), 12.5, 37.5, and 50 wt.%. Ion release, pH variation, and apatite formation (raman spectrometer and scanning electron microscopy–energy-dispersive X-ray spectrometry measurements) were analyzed. Results. The control group did not release any ions, while the experimental groups showed an increased release of Ca and P ions with higher concentrations of 45S5 BAG. The pH of the experimental groups remained consistently high. The 50 wt.% BAG group exhibited the formation of apatite peaks for a duration of 90 days. Additionally, a layer of apatite composed of Ca and P was precipitated on the surface and cross-section. Conclusions. This study suggests that a resin-based pit and fissure sealant containing 45S5 BAG can self-seal under microleakage between the tooth and restorative material. Therefore, the results of this study provide fundamental information that will be useful for the future development of resin-based pit and fissure sealants with long-term self-healing effects. Clinical Relevance. The resin-based pit and fissure sealant containing 45S5 BAG is a promising material for its apatite-forming ability for enamel remineralization.

“…Flowable composite materials have become widely used as pit and fissure sealant in the last two decades due to their favorable characteristics, including low viscosity, elasticity modulus and ease of use. The high particle rate of such materials, which are used in lesser thicknesses than resin-based pit and fissure sealants, has been indicated to decrease porosity, increase wear resistance and decrease polymerization shrinkage rates [10][11][12].…”

Pit and fissure sealants play an essential role in preventive dentistry. This study evaluates the microleakage levels of a new and colored flowable composite applied as a sealant after three preparation techniques. A total of 24 non-carious mandibular permanent molars with deep pits and fissures were included in the study. Pit and fissures were prepared with 37% phosphoric acid, tungsten carbide bur and fissurotomy burs (SS WHITE Dental, New Jersey, USA) using conventional, enameloplasty and fissurotomy techniques. All samples were thermocycled following the placement of Rainbow Flow (PPH CERKAMED Wojciech Pawłowski, Poland) as a sealant and sections were taken after immersion in methylene blue dye. The microleakage levels of the samples were examined under a stereomicroscope (Olympus SZX-7 Olympus SZ-61 Stereo Microscope) at 2.8× magnification to analyze the dye penetration of the flowable composite. The 144 sections were examined and scoring for microleakage was done by examining the dye penetration from the occlusal border to the base of the fissure. Considering all sections regardless of the preparation technique, it was found that 16.6%of the sections have no leakage. Regarding the microleakage scores, the mean score of the conventional group was 1.87 ± 0.98, the mean score of the enameloplasty group was 1.88 ± 1.14, and the mean score of the fissurotomy group was 1.81 ± 1.1. The median scores of the conventional, enameloplasty and fissurotomy groups were 2, 2 and 1.5, respectively. The present study reports no difference between the microleakage level of a colored flowable composite material used as a pit and fissure sealant following three fissure preparation techniques and supports the clinical use of this material.
