“…Levine et al [137] and Causton and Johnson [138] studied the use of mineralizing solutions. The use of citric acid was found unfavorable as, although it resulted in improved adhesion [136], it also opens up dentinal tubules and causes loss of the smear layer. An experimental study [8] assessed the effectiveness of adhesion of GPCs to substrates pre-treated with chemical reagents that are less aggressive than citric acid, which include PAA, ferric acid and tannic acid.…”

Abstract Glass polyalkenoate cements (GPCs) have been used in dentistry for over 40 years. These novel bioactive materials are the result of a reaction between a finely ground glass (base) and a polymer (acid), usually poly(acrylic acid) (PAA), in the presence of water. This article reviews the types of PAA used as reagents (including how they vary by molar mass, molecular weight, concentration, polydispersity and content) and the way that they control the properties of the conventional GPCs (CGPCs) formulated from them. The article also considers the effect of PAA on the clinical performance of CGPCs, including biocompatibility, rheological and mechanical properties, adhesion, ion release, acid erosion and clinical durability. The review has critically evaluated the literature and clarified the role that the polyacid component of CGPCs plays in setting and maturation. This review will lead to an improved understanding of the chemistry and properties of the PAA phase which will lead to further innovation in the glass-based cements field.

“…4 In addition, several fluoride-releasing cements have been developed and used clinically to reduce decalcification. [5][6][7] Glass ionomer cements (GICs) were initially introduced as orthodontic bonding adhesives to take advantage of some of their desirable characteristics, namely, their ability to chemically bond to tooth structure 8,9 and sustain fluoride release following bonding. [10][11][12][13][14][15][16][17] Fluoride release was shown to increase in the plaque adjacent to brackets bonded with GICs, 18 but their use in orthodontics was limited because of their lower bond strengths.…”

Objective: To evaluate a new self-etch conditioner used with resin-modified glass ionomers (RMGIs) in bonding orthodontic brackets. Materials and Methods: Sixty human molars were cleaned, mounted, and randomly divided into three groups. In group 1 (control), 20 orthodontic brackets were bonded to teeth using Transbond Plus Self-etching Primer; in group 2, 20 brackets were bonded using an RMGI with a 10% polyacrylic acid conditioner. In group 3, 20 brackets were bonded using Fuji Ortho LC with a new norinse self-conditioner for RMGIs. The same bracket type was used on all groups. The teeth were debonded in shear mode using a universal testing machine, and the amount of residual adhesive remaining on each tooth was evaluated. Analysis of variance was used to compare the shear bond strength (SBS), and the 2 test was used to compare the Adhesive Remnant Index (ARI) scores. Results: There were no significant differences in the SBS (P ϭ .556) between the groups. The mean SBS for Transbond Plus was 8.6 Ϯ 2.6 MPa, for Fuji Ortho LC using 10% polyacrylic acid 9.1 Ϯ 4.6 MPa, and for Fuji Ortho LC using GC Self-conditioner 9.9 Ϯ 4.1 MPa. The comparisons of the ARI scores between the three groups ( 2 ϭ 35.5) indicated that bracket failure mode was significantly different (P Ͻ .001), with more adhesive remaining on the teeth bonded using Transbond. Conclusions:The new self-etch conditioner can be used with an RMGI to successfully bond brackets. In addition, brackets bonded with Fuji Ortho LC resulted in less residual adhesive remaining on the teeth.

“…Resin modified glass ionomer (RMGI) is a hybrid cement [7], which adheres chemically with the tooth surface [8][9][10]. It was introduced to overcome the high clinical failure rates of conventional glass ionomer [11] and the high susceptibility of the resin to wetness [12][13][14].…”

“…While some studies recommend such preparation [17], Chung et al [18] mentioned that such a need is still unclear and that wetness does not have a negative effect on the bond strength. So RMGI can be used in wet condition without etching [9,13,[19][20][21][22].…”

Many theories have been proposed to explain adhesion mechanism between brackets and enamel surface. Chemical and mechanical adhesion are the main types [1]. Conventional bonding methods use phosphoric acid to prepare the enamel surface before bonding, increasing its capability to the adhesion by creating micro pores on the surface [2][3][4]. Although this technique increases bond strength, it is a multi stages method [5] and needs stern isolation procedures, as moisture weakens the bond strength [6]. Several studies were made to decrease the disadvantages of using phosphoric AbstractBackground. Many adhesive systems have been investigated as alternatives to conventional bonding methods. Selfetching primers and resin modified glass ionomer cement have been introduced to overcome the disadvantages of acid etching Objectives. To assess the effect of using either a self etching primer (SEP) or a resin modified glass ionomer (RMGI) on shear bond strength and failure type in comparison with conventional methods (CM). Material and Methods. Eighty metal brackets were bonded to buccal surfaces of human upper premolars by the same clinician according to 1of 4 protocols. Group 1, Transbond XT was used with self-etching primer (SEP) Transbond Plus (3M Untiek, Monrovia, Calif). Group 2, resin modified glass ionomer (RMGI) Fuji Ortho LC (GC Crop, Japan). Group 3, light cure resin (LC) Transbond XT (3M Unitek, Monrovia, Calif) were used with 37% phosphoric acid. Group 4, Chemically cure resin (CC) Unite (3M Unitek, Monrovia, Calif) were used with 37% phosphoric acid. The premolars were stored in distilled water for 24 hours at 4ºC. Brackets were loaded to failure in Instron machine. Descriptive statistics were calculated. ANOVA, Bonferroni, Kruskal-Wallis tests and MannWhitney U were used. Results. The present study indicated that the SEP provided no significantly higher shear bond (10.01 ± 5.46 MPa) than LC adhesive (8.59 ± 4.07 MPa) while RMGI showed the lowest (5.08 MPa). A comparison of the adhesive remnant index (ARI) scores indicated that there was significantly difference between the groups with less residual adhesive remaining on the teeth with SEP and RMGI. Conclusions. SEP produced bond strength clinically accepted with less amount of residual adhesive left on the enamel while RMGI produced unacceptable bond strength. SEP can use successfully in bond orthodontic brackets (Dent. Med. Probl. 2016, 53, 1, 50-55).
