A Study of the Penetration of Sealants into Pits and Fissures
Journal of the American Dental Association, 1973An investigation was conducted into the penetration of different resin sealants into the pits and fissures of extracted molariform teeth of humans. The results showed that prophylaxis before conditioning and sealant placement only cleaned the cuspal inclined planes and that pits and fissures often remained filled with debris.

International Journal of Paediatric Dentistry, 2012 International Journal of Paediatric Dentistry 2013; 23: 13–22 Background. Optimal pit and fissure sealing is determined by surface preparation techniques and choice of materials.Aim. This study aimed (i) to compare the microleakage and penetration depth of a hydrophilic sealant and a conventional resin‐based sealant using one of the following ...

Comparison of sealant and infiltrant penetration into pit and fissure caries lesions in vitro
Journal of Dentistry, 2014The aim of this in vitro study was to evaluate the penetration of an infiltrant and a sealant, when applied as recommended, into fissure caries lesions.The fissure systems of extracted human teeth were classified according to the international caries detection and assessment system (ICDAS, codes: 0, 1, 2).

summary Fissure sealants have been used successfully as a means of preventing fissure caries. This effectiveness is directly related to sealant retention and retention is dependent upon a meticulous method of application. The aims of this study were to determine if sealant adhesion and penetration were affected by the variation in preparation of ...

Effect of surface-penetrating sealant on composite wear
Dental Materials, 1993The wear resistance of posterior composites has improved dramatically over the last several years. Compared to the original formulations, many of the currently available composites exhibit wear rates of less than 10% of their early predecessors. Nevertheless, much research has been directed toward improving this property to a higher level.

Radon Penetration of Concrete Slab Cracks, Joints, Pipe Penetrations, and Sealants
Health Physics, 1997Radon movement through 12 test slabs with different cracks, pipe penetrations, cold joints, masonry blocks, sealants, and tensile stresses characterized the importance of these anomalous structural domains. Diffusive and advective radon transport were measured with steady-state air pressure differences controlled throughout the deltaP = 0 to 60 Pa ...

Assessing the Long-Term Effect of a Surface Penetrating Sealant
The Journal of the American Dental Association, 1993Small defects are commonly found on the surfaces of composite restorations--especially in stress-bearing areas. Sealant application may reduce the wear rates of these restorations. This five-year study assesses the effect of sealant application on interfacial staining, clinical wear, marginal integrity and surface texture.
