Purpose :Evaluate clinical and radiographic changes in primary teeth submitted to indirect pulp capping (IPC) over a 48-month-period. Methods: Twenty seven primary molars with deep caries, but without preoperative signs of irreversible pulpits, were treated with IPC. The teeth were randomly divided into two groups, according to the material used for protection of the dentin-pulp complex: (1) a calcium hydroxide liner(Dycal®) and (2) glass ionomer cement (Vitremer®). Results: After 48 months, Group-1 showed a success rate of 88.8% and Group-2 of 93%. No statistical significant difference between the groups was observed(P = 0.62). CLINICAL SIGNIFICANCE: The results of this study suggested that indirect pulp capping in primary teeth arrests the progression of the underlying caries, regardless of the material used as a liner.

AbstractObjective:To study the biomechanical properties of glass ionomer cement used for incudostapedial rebridging.Methods:Two groups were established based on the size of the gap between the incus and stapes (1.0 mm in group 1 and 2.0 mm in group 2). Glass ionomer cement was applied to the gaps, and compression tests were performed. Maximum force was measured at the fracture point, and was divided by the cross-sectional area to obtain the maximum compressive strength.Results:No significant difference was found in the maximum force for the two groups (p = 0.312). The glass ionomer cement diameter was significantly higher in group 2 than in group 1 (p = 0.006). The maximum compressive strength was significantly higher in group 1 than in group 2 (p = 0.042).Conclusion:The fragility of bone cement used in this study was 25.5 per cent higher for a 2 mm gap than for a 1 mm gap. We speculate that the use of bone cement may be safer for the repair of smaller incudostapedial defects.

Abstract Objective: To evaluate the influence of enamel etching on tensile bond strength of orthodontic brackets bonded with resin-reinforced glass ionomer cement. Materials and Methods: The sample group consisted of 15 patients who had indications for extraction of four premolars for orthodontic reasons, equally divided into two different groups according to bracket and enamel preparation. Brackets were bonded in vivo, by the same operator, using a split mouth random technique: Group 1 (control), phosphoric acid + Fuji Ortho LC; Group 2, Fuji Ortho LC without acid conditioning. The teeth were extracted after 4 weeks using elevators. An Instron Universal Testing Machine was used to apply a tensile force directly to the enamel-bracket interface at a speed of 0.5 mm/min. The groups were compared using a Mann-Whitney U-test and Weibull analysis. Results: Mean results and standard deviations (in MPa) for the groups were: Group 1, 6.26 (3.21), Group 2, 6.52 (2.73). No significant difference was observed in the bond strengths of the two groups evaluated (P = .599). Conclusions: Fuji Ortho LC showed adequate shear bond strength and may be suitable for clinical use.

Background: Class II restoration with zirconia inlay is concerned by numerous studies about the luting coupling between zirconia inlay and teeth. The present study was performed to evaluate the microleakage of Class II zirconia inlayusing two different luting agents and compare to direct restoration using bulk fill composite. Aims: To evaluate the microleakage of Class II restorations using three different techniques. Materials and methods: The study was performed in laboratory with three groups. Each of thirty extracted human teeth was prepared a class II cavity with the same dimensions, then these teeth were randomly divided into 3 groups restored by 3 different approaches. Group 1: zirconia inlay cemented with self-etch resin cement (Multilink N); Group 2: zirconia inlay cemented with resin-modified glass ionomer cement (Fuji Plus); Group 3: direct composite restoration using bulk fill composite(Tetric N-Ceram Bulk Fill). All restorations were subjected to thermal cycling (100 cycles 50C – 55 0C), then immersed to 2% methylene blue solution for 24 hours. The microleakage determined by the extent of dye penetration along the gingival wall was assessed using two methods: quantitative and semi-quantitative method. Results: Among three types of restorations, group 1 demonstrated the significantly lower rate of leakage compared to the others, while group 2 and 3 showed no significant difference. Conclusion: Zirconia inlay restoration cemented with self-etch resin cement has least microleakage degree when compare to class II zirconia inlay restoration cemented with resin-modified glass ionomer cement and direct composite restoration using bulk fill composite. Key words: inlay, zirconia ceramic, class II restoration, microleakage.

Introduction. Despite the development of restorative dentistry bond between materials and hard dental tissues is still not satisfying and often leads to marginal discoloration, microleakage, secondary caries and postoperative sensitivity. The aim of this study was to examine the clinical efficacy of different liners and oxalate-based desensitizer in preventing the occurrence of postoperative sensitivity. Material and Methods. This clinical study included 120 patients in which two homologous contralateral posterior teeth were restored with composite material and different liners. Patients were divided in three groups, depending on applied liner. In each patient, before the application of composite material in one tooth the liner was placed, while in the other tooth both the desensitizer and the same liner were used. The following liners were used: Calcimol LC, ANA Liner, Fuji II LC; desensitizer: BisBlock and composite material: Ceram-X Mono. Results. Teeth restored using Calcimol LC were the most sensitive after treatment whereas teeth restored with Fuji II LC showed the least postoperative sensitivity (Calcimol LC > ANA Liner > Fuji II LC). In the group of teeth restored with BisBlock postoperative sensitivity was observed in 6.7% restorations, while in the group where desensitizer was not used, sensitivity was noted in 15.8% of cases. There was statistically significant difference in the incidence of postoperative sensitivity between the group where desensitizer was used vs. group where it was not used (p<0.05). Conclusion. Glass-ionomer cement is more efficient in preventing postoperative sensitivity compared to compomer and light-curable calcium hydroxide in posterior composite restorations. The use of desensitizer reduced significantly the incidence of postoperative sensitivity.

Background: Giomer is a unique class of restorative material has been introduced as the true hybridization of Glass Ionomer (GI) and composite resin and has the distinguishing feature of a stable surface pre-reacted glass ionomer. Glass Ionomer Cements (GIC) are also unique restorative materials with many uses in clinical practice and provide for caries-protective fluoride releasing at the margins of restorations, as well as their ability to have the fluoride within their chemical matrix recharged by outside exposure to other fluoride-containing materials. The present study aim at clinically evaluate the comparison between the glass Ionomer cement and Giomer for the management of cervical caries. Materials and methods: The study was a cross sectional comparative study which was carried out from 01 December 2018 to 31 November 2019 in the Department of Conservative Dentistry and Endodontics, Bangladesh Dental College, Dhanmondi, Dhaka. Total number of cases was 80. The patients were divided into two groups, half of the patient (Group-1) was treated with Glass Ionomer cement and half of the patient (Group-2) was treated with Giomer restoration. The post-operative sensitivity discoloration, dislodgement of filling material and secondary caries formation were recorded. All the patients were assigned and the data were analyzed statistically by SPSS version 21. p-value < 0.05 was taken as significant. Results: The study reveals 60% of the study population was within 41 to 50 years of age group (Group-1) and 62.5% were 51 to 60 years (Group-2) 45% in (Group-1) and 10% in (Group-2) had history of post filling sensitivity, 12% in (Group-1) and 5% in (Group-2) had discoloration after restoration, 2.5% had history of dislodgement of the filling in (Group-1), no history of dislodgement of the filling in (Group-2), 2.5% had history of secondary caries formation in (Group-1) and no history of Secondary caries formation in (Group-2). Conclusion: Patients were more approachable for Giomer restoration than Glass ionomer for the management of cervical caries over a period of 12 month.

Introduction: Microleakage is an important property that has been used in assessing the success of any restorative material used in restoring a tooth. Immediate application of a surface coating agent is suggested to protect glass ionomer cement against moisture contamination and dehydration during early setting. Aim: To compare marginal microleakage of two different Glass Ionomer Cement (GIC)- Conventional GIC and Resin Modified GIC in primary anterior teeth using three surface coating materials. Materials and Methods: An in vitro study was conducted between January 2014 to October 2017 on freshly extracted 40 anterior primary teeth which were randomly assigned into two main groups (Fuji II GIC and Fuji II LC GIC) with four subgroups (control-no surface coating, A=GC Fují Varnish II, B=GC G-Coat Plus, C=Icon). A standardised Class V cavity preparation was prepared on the labial surface of each tooth. Specimens were coated with two layers of nail varnish, leaving a 1 mm window around the cavity margins and placed in a solution of Methylene blue Dye for 24 hour at 37°C. The teeth were sectioned longitudinally in a buccolingual direction of the restorations and evaluated under stereomicroscope to check extent of dye penetration. The results were analysed by ANOVA and Tukey’s post-hoc test (p≤0.05). Results: It was found that maximum microleakage was seen in group 1 (Fuji II GIC) as compared to group 2 (Fuji II LC GIC) and it was non-significant (p=0.53). Ascending order for mean microleakage for Group 1 was as follows: Control >GC Fuji Varnish >Icon DMG >GC G-Coat and for Group 2: Control >GC Fuji Varnish >Icon DMG >GC G-Coat. Icon when compared with Gc coat and Varnish also showed non-significant (p=0.137) difference in Group 2. Conclusion: All three different surface coatings can seal glass ionomer restorations. The GC G-Coat Plus has the least microleakage on Resin-Modified GIC (RMGIC) compared to the other surface coatings. This would aid the clinicians to make appropriate decision regarding the choice of material to be used for restoration and coating in anterior primary teeth.

ABSTRACT Objective: To evaluate and compare two treatment protocols to correct anterior dental crossbite in the mixed dentition. Materials and Methods: Thirty children, 8–10 years of age, participated. Individuals were divided into two groups. Group 1 consisted of 15 children treated with an upper removable appliance with finger springs; group 2, 15 children treated by bonding resin-reinforced glass ionomer cement bite pads on the lower first molars. The 30 participants were evaluated before treatment (T1) and 12 months after treatment began (T2). The variables evaluated included overjet, perimeter of the maxillary arch, intercanine distances in the maxilla and mandible, SNA, SNB, ANB, and U1.NA. Data analysis included descriptive statistics, paired t-test and Student's t-test. Effect sizes and confidence intervals were also calculated. Results: Group 1 showed a significant increase in overjet (P &lt; .001), intercanine distance in the maxilla (P = .006), intercanine distance in the mandible (P = .031), and U1.NA (P = .002). Group 2 showed a significant increase in overjet (P = .008), intercanine distance in the mandible (P = .005), and U1.NA (P &lt; .001). For all the evaluated variables, no statistically significant differences were observed between the two groups. Conclusions: No significant differences were observed between the two protocols: use of a removable maxillary biteplate with finger springs and bonding of resin-reinforced glass ionomer cement bite pads on the lower first molars, for the correction of anterior crossbite in the mixed dentition.

Backround: Smear layer formed during cavity preparation interfere with the adhesion between restoration and tooth structure and is considered a barrier that would degrade the quality of adhesion. Smear layer does not have a stable substrate for adhesion, gradually layer dissolves in the restorative material and cause microleakage, penetration of bacteria and inflammation of the pulp. Adhesion to dentin is more difficult to achieve than enamel, therefore the cleaning procedure on dentin require special treatment. Conditioner form a weak acid is used to remove the smear layer and surface contamination on the email or dentin which can reduce the adhesion of the material and the tooth surface. Dentin conditioner is an acid material containing 10% polyacrylic acid conditioner while Cavity conditioner an acid material containing 20% polyacrylic acid and 3% aluminum chloride. The higher the concentration, the more smear layer is dissolved in order to obtain adhesion of glass ionomer cements better because it is not blocked by the smear layer. Purpose: The purpose of this laboratory research is to study the shear bond strength of glass ionomer cement in dentin after application dentin conditioner and cavity conditioner .Material and Method: Twenty seven bovine cow's teeth were divided into three groups. Each group consisted of nine samples. Group 1 was control (without conditioner). Group 2 was treated with the Dentin conditioner. Group 3 was treated with the Cavity conditioner. Result: The average shear bond strength in group 1 is 3.31 Mpa, group 2 is 7.74 MPa and group 3 is 9.92 Mpa. Conclusion: There is a significant difference between third group and the shear bond strength of glass ionomer cement on dentin with application of the Cavity conditioner is higher than with application of the Dentin conditioner and without application conditioner

Aims and Objectives: In recent years, researchers have focused on finding methods of eliminating caries and white spot lesions under orthodontic bands without requiring patient cooperation. One of the effective and preventive strategies is the addition of antibacterial and remineralizing agents to the band cement. However, modifying the cement should not lead to microleakage and weakening of its mechanical properties. This in vitro study represents a continuation of our previous work of investigating the retentive strength of orthodontic bands cemented with casein phosphopeptide-amorphous calcium phosphate (CPP-ACP)-modified glass ionomer cement (GIC). Material and Methods: 60 extracted human premolars were randomly divided into two groups (n = 30). In group 1, stainless steel bands were cemented with GIC. In group 2, a novel dental caries-preventive material, CPP-ACP, was incorporated into the GIC for cementing. The microleakage of each group was measured by the fluid filtration method. Results: Results showed no statistically significant difference in microleakage of either group (GIC and CPP-ACP-modified GIC). Conclusion: We concluded that 1.56% w/w CPP-ACP can be incorporated with GIC for cementing orthodontic bands without promoting microleakage.
