Assessment of the inhibitory effects of fissure sealants on the demineralization of primary teeth using an automatic pH-cycling system

Abstract

In this study, we examined the effects of fissure sealants on inhibition of demineralization of primary teeth using an automatic pHcycling system. Three fissure sealants were used: Teethmate F-1 2.0 (TM), BeautiSealant (BS), and Fuji III LC (IIILC). Using an automatic pH-cycling system, the specimens (n=12) were repeatedly demineralized and remineralized. Specimens were subjected to transverse microradiography (TMR), and changes in integrated mineral loss (IML) and lesion depth (Ld), indicated as ΔIML and ΔLd, respectively, were calculated. In addition, fluoride levels in the enamel were assessed using microparticle-induced gammaray emission/particle-induced X-ray emission (n=3). IIILC showed the lowest values for ΔIML and ΔLd, followed by BS and then TM. The highest amount of fluorine in the enamel was observed for IIILC, followed by TM and BS. All fissure sealants inhibited demineralization in primary teeth.

Shear bond strength and microleakage of a new self-etch adhesive pit and fissure sealant

“…However, extremely high microleakage values greater than those observed in our study have also been reported 16) . Few studies have assessed its additional fluoride-releasing property 6) and pH buffering mechanism 7,8) . Though these cariostatic properties were not measured in this study, its use in clinical settings has to be decided based on weighing both its physical and cariostatic properties.…”

“…The application of self-etching adhesives instead of acid etching might simplify the clinical workflow, reduce application times and achieve acceptable cooperation from children. Most recently, a new product (BeautiSealant, Shofu, Kyoto, Japan) featuring reduced working time and fluoride-releasing and pH-buffering properties was released on the dental market [6][7][8] . Stringent testing of new materials is imperative before formulating clinical recommendations.…”

Güncel Fi̇ssür Örtücüler – Li̇teratür Derlemesi̇

“…Bu sonuçlara ek olarak, minede flor seviyeleri ölçüldüğünde yine en yüksek verileri rezin modifiye cam iyonomer içerikli fissür örtücünün gösterdiği, en düşük değerlerin ise giomer esaslı fissür örtücüden elde edildiği gösterilmiştir. 42 Yapılan diğer bir çalışmada, florid içerikli iki farklı rezin esaslı fissür örtücü, giomer bazlı örtücü ve geleneksel cam iyonomer simanın kümülatif florid salımını karşılaştırılmıştır. Çalışma sonucunda, en düşük florid salımının giomer grubunda olduğunu, materyallerin 5 günlük uygulama sonrası reşarj kapasitelerinin incelendiği aşamada ise giomer bazlı örtücülerin rezin esaslı örtücülerden daha yüksek fakat geleneksel cam iyonomer simandan çok daha düşük seviyede flor salımı gerçekleştirdiğini bildirmişlerdir.…”

Fully Automated Bioreactor-Based pH-Cycling System for Demineralization: A Comparative Study with a Conventional Method

“…The pH-cycling model, which was developed to replicate pH changes in the oral cavity caused by food and drink consumption, has been widely accepted and utilized in the scientific and dental industries as an appropriate alternative method for investigating the caries prevention effects of fluoride application in humans and animals [5,9]. Several pH-cycling models, including manual and automated models, have been developed for both caries and erosive lesions [10][11][12][13]. Automation through microcontroller control has been particularly effective in addressing issues such as forgetting to exchange solutions and preparation errors and also reduced operator errors [5,10,14].…”
