OBJECTIVES To evaluate the surface properties of two commercially available sealants (Pro Seal® (PS) and Opal® SealTM (OS)) in terms of fluoride(F) release, biofilm formation of Streptococcus mutans and Lactobacillus and the ability to resist acid penetration. SETTING University of Nebraska Medical Center. MATERIAL & METHODS Discs of similar diameter and thickness were made from OS and PS. Discs were soaked in double-distilled water, and F released was measured with fluoride meter daily for…

Comparison between the effectiveness of two sealants in prevention of enamel white spot lesions: in vitro study

Comparing the effectiveness of using highly filled and lightly filled sealants in preventing demineralization and resisting acid and abrasion through assessing enamel color change differences and sealant retention after induced challenges found the best protection was seen in the Opal seal group after the 1st acidic challenge.

Orthodontic Bond Strength Comparison between Two Filled Resin Sealants.

Opal Seal and Pro Seal sealants have similar SBS but generally exhibit lower bond strengths than an adhesive primer, and the Opal Seal group had significantly greater ARI scores, indicating that more adhesive remained on the teeth after debonding.

OCT evaluation of orthodontic surface sealants: a 12-month follow-up randomized clinical trial

Objectives The aim of this single-center randomized controlled trial (NCT03753256) was to assess orthodontic surface sealant layer thickness and integrity in vivo during a 12-month follow-up by

Fluoride Ion Release Characteristics of Fluoride-Containing Varnishes—An In Vitro Study

There was a significant difference between the tested fluoride varnishes at all measurement times and a solitary product application of only once or twice per year, as stated by the manufacturers, cannot be supported.

The review showed that the use of orthodontic sealants in preventing WSLs during and after fixed orthodentic treatment is significantly effective, however, the bioactive glass is deemed more effective against WSL development due to its ability to immediately repair enamel surface, low cytotoxicity, and high biocompatibility.

A Novel Dental Caries Model Replacing, Refining, and Reducing Animal Sacrifice

The developed in vitro caries model presented in this study may be a novel animal sparing model for caries disease studies and can be used widely to evaluate the efficacy of different antibacterial dental materials.

Shear bond strength after using sealant before bonding: a systematic review and meta-analysis of in vitro studies

There is no additive benefit for shear bond strength when using sealant before bonding, and additional randomized controlled studies should be performed to analyze impact of sealants on bonding strength and bracket loss in more detail.

Phage Targeting Streptococcus mutans In Vitro and In Vivo as a Caries-Preventive Modality

This study shows how SMHBZ8 phage therapy targeting S. mutans can serve as an efficient caries-prevention modality, in suspension or with a sustained-release delivery system, by in vitro and in vivo mouse models.

The effectiveness of Resin-Modified Glass Ionomer Varnish in Preventing White Spot Lesions During Fixed Appliance Orthodontic Therapy: An In Vitro Study

This work focuses on the development and treatment of White Spot Lesion Development and Orthodontic Treatment, and the aims and methods used to achieve these goals.

Comparing the Color Masking Effect of ICON and PROSEAL on Primary Enamel White Spot Lesions- A Randomized Controlled Clinical Trial

Both ICON and PROSEAL were successful in masking of WSLs in primary teeth, however the difference between the two groups wasn’t statistically significant.



An in-vitro evaluation of mechanical and esthetic properties of orthodontic sealants

Both orthodontic sealants are beneficial for protecting enamel, however with better wear properties PS was superior in resisting mechanical stresses.

Inhibition of Acid Production from Oral Bacteria by Fluorapatite-derived Fluoride

Results provide further support to the hypothesis that fluoride levels in plaque and enamel, achievable through use of fluoridated water and/or fluoride dentifrices, may produce appreciable inhibition of glycolysis at the acidic pH levels which are readily achieved in plaque.

Prevention and reversal of dental caries: role of low level fluoride.

Low but slightly elevated levels of fluoride in saliva and plaque provided from these sources help prevent and reverse caries by inhibiting demineralization and enhancing remineralizations.

Comparison of artificial caries-like lesions by quantitative microradiography and microhardness profiles.

A direct comparison of quantitative microradiography and microhardness profiles was made using artificial caries-like lesions in human enamel. Tooth crowns with lesions were cut in half through the ce
