Öz AbstractFluoride released from restorative materials decreases demineralization, increases remineralization, and inhibits secondary caries with its antibacterial effect. The use of fluoride-releasing dental materials in pediatric dentistry has currently gained importance. Conventional glass ionomer cements (high-viscosity glass and cermet ionomer cements), resin-modified glass ionomer cements, nano-ionomer cements, compomers, glass carbomers, giomers and fluoride-containing composites are among the fluoride-releasing dental materials. In this study, fluoride-releasing properties of restorative dental materials used in pediatric dentistry were reviewed with respect to the current literature. Keywords: Glass carbomer, pediatric dentistry, fluoride GİRİŞDiş hekimliğinde kullanılan restoratif materyallerdeki gelişmeler, hekimlerin çürüğü uzaklaştırmada daha konservatif yaklaşmasına olanak sağlamaktadır. Doku koruyucu yaklaşım sonucunda diş yüzeyinde daha fazla enfekte doku ve mikroorganizma bırakılmaktadır. Bu durum florür salma özelliği ile remineralizasyonu arttıran ve antibakteriyel etki gösteren materyallerin geliştirilmesi ihtiyacını doğurmuş-tur. Böylece materyaller ikincil çürük oluşumunu engelleyecek ve mikrosızıntıyı azaltacaktır (1).Florür iyonunun diş hekimliği açısından önemi Avrupa'da ilk kez ondokuzuncu yüzyılın sonlarına doğru belirlenmiş ve çalışmalarla kanıt-lanmıştır. Florürün çürük önleyici etkisi üç yolla gerçekleşir (2):1. Demineralizasyonu önleyici etki 2. Remineralizasyonu arttırıcı etki 3. Antibakteriyel etki Ağız ortamının pH'sı düştüğünde mine yüzeyinden Ca +2 ve PO 4 +3 uzaklaşarak dişte demineralizasyonu başlatır. Tükürükte ve diş sert dokuları çevresinde az miktarda ve sürekli olarak bulunan florür ortamın pH'sı azaldığında floroapatit olarak minede birikir ve minenin çö-zünürlüğünü azaltarak, demineralizasyonu önler. Asidik etki ortadan kalkınca Ca +2 ve PO 4 +3 tekrar diş yüzeyine geri döner, bu da remineralizasyondur. Florür, remineralizasyonu sağlamakta katalizör görevi görür. Minenin mineral yapısına katılarak hidroksiapatiti, çözünmeye daha dirençli olan floroapatite dönüştürür. Böylece minenin aside direnci artar ve remineralizasyon sağlanarak diş çürüğünün ilerlemesi durdurulur. Florür ayrıca bakteriyel enzimleri inhibe ederek bakteriyel asit oluşumunu önler. Böylece bakterilerden kaynaklanan asitlerin neden olduğu erken dönem diş çürüklerinin önlenmesini sağlar (3, 4). Florürün bu etkilerinden dolayı günümüzde florür salan dental materyallerin çocuk diş hekimliğinde kullanımı önem kazanmıştır.Materyallerden florür salımının üç ayrı mekanizma ile gerçekleştiği bildirilmektedir. Bunlar yüzeyden yıkanma, gözenek ve çatlaklardan difüzyon ve hacimden difüzyon olarak sıralanmaktadır. Materyalin sertleşmesinden bir gün sonra oluşan ve yeniden florürle yüklen-mesinden bir gün sonra görülen en yüksek düzeydeki florür salımının yüzeyden yıkanma şeklinde olduğu bildirilmektedir. Gözenek ve çatlaklardan difüzyon yolu ile oluşan salım ise, daha az ancak daha sabit düzeyde ve ilk günden so...

INTRODUCTION:Fluoride-releasing restorative materials can be used as a reservoir releasing small amounts of fluoride to the teeth over a long time.Giomer represents a new class of dental materials that uses the pre reacted glass technology (PRG) with excellent mechanical and esthetic properties. OBJECTIVES: The aim of this study is to evaluate the fluoride release ability of Giomer (Beautifil II) compared to Compomer (Dyract XP) and their fluoride recharge ability after exposure to topical fluoride varnish. MATERIALS AND METHODS:The sample consisted of 80 freshly extracted primary anterior teeth. Standardized buccal class V cavities were prepared. Sample was randomly divided into 2 groups: Group I: included 40 teeth restored with Beautiful II. Group II: included 40 teeth restored with Dyract XP following the manufacturer's guidelines. Fluoride release was evaluated in the artificial saliva on 1st, 7th, 14th and 21st days. After 21days of release, 5%NaF varnish was applied on buccal surface of all specimens. The amount of fluoride release after recharge was measured in the artificial saliva after 1st, 7th, 14th and 21st days using fluorine ion-specific electrode. Data were analyzed using Friedman's two-way analysis of variance by ranks, Dunn-Sidak method, Mann-Whitney U test and Wilcoxon Signed Ranks to achieve the aim of the study. RESULTS: Beautiful II released significantly higher amount of fluoride compared to Dyract XP in first 7 days at p<0.0125. Dyract XP released significantly higher amount of fluoride after 14 and 21 days at p<0.0125. After 5%NaF varnish treatment there was no significant difference in fluoride re-release amount of both Beautiful II and Dyract XP at p>0.0125. CONCLUSIONS: Fluoride release (ppm) was found to be significantly higher in Beautiful II than Dyract XP in the first week. Giomer could be considered a suitable class V restoration of primary teeth in high caries risk children.

“…In the structure of giomer restorative materials are glass ionomer particles which have formed from a previous reaction to provide production of glass ionomer. By fluoride aluminium previously entering into a reaction with silicate glass polyacid, giomers which form the glass ionomer matrix are then included in the resin producing silica filler (38).…”

In the field of restorative dentistry, the use of composites has become widespread with increasing aesthetic demand. Nowadays the composites are divided into various classes depending on the type and size of the filler particles. Apart from this, many new composites have been produced in order to protect the healthy tooth structure, to reduce microleakage and secondary caries formation, to reduce marginal pigmentation and postoperative sensitivity together with developments in technology. The aim of this review is to improve the clinical performance and to evaluate new composite resins that will provide more selection criteria for dentists.
