“…Advantages of the in vitro model are that it ensures a highly precise instrumental measurement setting, a standardized environment, and controlled staining procedures. The in‐vitro model also ensured precise sealant application without moisture contamination, which might have resulted in some uneven sealant surfaces . Because it is impossible to postulate that every tooth behaves in an identical way when stained, each specimen served as its own control: one half of its surface was sealed and the other half was left unsealed as a control.…”

“…We cannot, however, exclude the possibility that the greater surface roughness of the filled sealer caused greater adhesion of staining particles. In this context, it should be noted that most filled composite‐based sealants seem more resistant to mechanical wear (e.g., daily brushing) than their unfilled counterparts . Because composite‐based sealants provide an intact layer of material which protects the enamel from acid‐forming microorganisms, it could be expected that this sealant type has a caries‐resistant effect …”

“…Anfe et al showed that staining caused by coffee and red wine occurs in a superficial layer (depth <20 μm), which can be removed by polishing . Sen et al investigated how professional tooth cleaning using a polishing brush affected surface layer thickness changes for Pro Seal, Light Bond, and for Opal Seal, a glass ionomer‐based, filled sealant . Directly after application, mean measured film thickness varied from 69 μm (Light Bond) to 134 μm (ProSeal).…”

“…These sealed tooth surfaces may discolor during treatment, negatively affecting the patient's appearance. More than 90% of orthodontic practices in Germany currently use resin‐based (filled or unfilled) sealants and various varnishes and liners for compliance‐independent prophylaxis; however, little information is available on the color stability of enamel sealants and, to the best of our knowledge, no study has yet compared the color stability of different orthodontic surface sealants . Hence, the main objective of this study was to evaluate and compare the color stability of different types of commercially available sealant materials after exposure to artificial aging and different staining solutions.…”

Objective To assess surface discoloration of four enamel sealants based on different chemical compositions after exposure to artificial aging and staining solutions. Furthermore, their cleanability after polishing will be evaluated. Materials and Methods Selected sealants were a composite resin‐based sealant with fillers (Pro Seal), a composite resin‐based sealant without fillers (Light BondSealant), a resin‐modified glass ionomer‐based sealant (ClinproXT Varnish) and a silicon‐based sealant (Protecto). Natural teeth served as medium. Immersion solutions were water, juice, tea, and turmeric. In a standardized setting, all samples were measured seven times with a spectroradiometer (Photoresearch PR670) at baseline, after thermocycling; 7 days; 2 and 4 weeks of immersion; and after finally polishing. Results Thermocycling had no significant effect on color stability. After exposure to staining solutions, all sealed surfaces showed significant color changes. Color change predominately occurred for all sealants in the first week of staining (P ≤ .01). Best resistance to staining decreased as follows: Protecto > Light Bond Sealant > ProSeal > Clinpro XT Varnish. Surface cleaning by polishing significantly reduced the color change. Conclusion Sealed enamel surfaces are prone to discoloration, which is most prominent in filled composite and glass‐ionomer‐based sealants. Staining can be reduced by polishing; however, in this in vitro setting the original color could not be restored. Clinical Significance Enamel sealants might exert adverse effects in terms of discoloration. This should be taken into consideration by clinicians and patients, particularly when sealants are applied in esthetically critical areas.

Purpose Surface sealants are widely used as a prevention strategy and are indicated for young patients with insufficient oral hygiene who also need plaque removal by professional tooth cleaning. The aim of this study was to evaluate discoloration of surface sealants by plaque disclosing solutions and to test to what extent this discoloration can be reduced again by professional tooth cleaning. Methods In all, 96 extracted lesion-free human teeth were randomly assigned to treatment with either Pro Seal ® (PS; Opal Orthodontics, South Jordan, UT, USA) or Opal ® Seal™ (OS; Reliance Orthodontic Products, Itasca, IL, USA). Color evaluations after application of the plaque disclosing solution Mira-2-Ton ® (Hager & Werken, Duisburg, Germany) were performed using a clinical spectrophotometer. Staining and polishing were repeated once. Color differences (E) above 3.77 were regarded as clinically relevant. Results All sealants showed high, clinically relevant E values after the first staining. Polishing led to significantly decreased E values on PS-treated teeth; however, the median E value remained above the clinically relevant threshold. Polishing on OS-treated teeth only slightly reduced E values. After professional tooth cleaning both PS and OS showed clinically relevant E values. Conclusion Surface sealants show clinically relevant discoloration after exposure to plaque disclosing solution under in vitro conditions. Such discolorations could not be removed by professional tooth cleaning. Thus, in clinical practice, plaque disclosing solutions might cause esthetic deficits in surface sealant-treated teeth. The impact of plaque disclosing solutions under clinical conditions (e.g., in the presence of saliva and by various aspects of a person's nutrition) should be investigated in clinical studies.
