ABSTRACT
Dental cements are in a constant state of evolution, adapting to better align with the intricacies of tooth structure and the dynamic movements within the oral cavity. This study aims to evaluate the efficacy of zirconia-reinforced glass ionomer cement-an innovative variant of modified glass ionomer cements-in terms of its ability to withstand compressive forces and prevent microleakage during dental caries reconstruction. An extensive search was conducted across various databases, encompassing PubMed-MEDLINE, Scopus, Embase, Google Scholar, prominent journals, unpublished studies, conference proceedings, and cross-referenced sources. The selected studies underwent meticulous scrutiny according to predetermined criteria, followed by the assessment of quality and the determination of evidence levels. In total, 16 studies were incorporated into this systematic review and network meta-analysis (NMA). The findings suggest that both compomer and giomer cements exhibit greater compressive strength and reduced microleakage values than zirconia-reinforced glass ionomer cement. In contrast, resin-modified glass ionomer cement (RMGIC) and high-viscosity glass ionomer cement (GIC) demonstrate less favorable performance in these regards when compared with zirconia-reinforced glass ionomer cement.
ABSTRACT
Aim: The aim of this study was to evaluate and compare eighth-generation bonding agent (G-Premio BOND) modified with 7% arginine and 0.12% chitosan for antibacterial property and microtensile bond strength. Methods: To evaluate antibacterial property, the sterile 96-microtiter plate was taken. The sidewalls of nine wells were coated with 15 µl of adhesive from each group. Suspension of Streptococcus mutans bacteria was placed on each group of adhesive and antibacterial property was checked using Spectrophotometer. Thirty-three healthy extracted premolars were taken and adhesive from each group was applied on the exposed surface of dentin, and the specimens were tested using a universal testing machine at crosshead speed of 1 mm/min. Results: The least antibacterial efficacy was seen with unmodified eighth-generation bonding agent. This result was statistically significant when all study groups were compared. Microtensile bond strength was evaluated and the highest mean value (5.07) was seen with adhesive modified with 7% arginine, followed by adhesive modified with 0.12% chitosan (mean value: 4.14), and unmodified adhesive had the lowest mean bond strength value (4.07). Conclusions: The eighth-generation bonding agent modified with 7% arginine and 0.12% chitosan showed antibacterial efficacy against S. mutans. In addition to this, they also had higher tensile bond strength values as compared to unmodified adhesive.
ABSTRACT
Traumatic injuries resulting in damage to the teeth and associated structures have a grave psychological impact on the patient and hence, these require timely intervention. The fracture extent determines the appropriate treatment plan for the patient. Crown fractures can be treated aesthetically without the invasion of the biological width with meticulous interdisciplinary management. The objective of this article is to report a case of a 27-year-old Indian male patient who presented to our hospital the following day, post-trauma to the anterior teeth. On clinical examination, two teeth were found to have undergone fracture that involved the pulp chamber. Considering the overall oral health, pulpal and periodontal health, availability of the fragments, and invasion of the biological width, a tailor-made treatment plan was devised. The fractured crown fragments were reattached surgically, using a glass fiber post that resulted in an aesthetic biological restoration. This treatment has been successfully managed by an interdisciplinary approach. At the 18th-month follow-up, clinical and radiological examinations suggest a successful outcome.
