“…In this study also Aluwax was found to be the least dimensionally stable (Table 1). This finding is in congruence with the results of studies conducted by Felipe Lozano et al and Gupta et al 6,7 It also showed the greatest change in surface hardness of all the materials tested after disinfection (Table 2). This finding was in accordance with a study conducted by GS Chandu et al where resistance to compression was tested for various interocclusal record materials.…”

The importance of disinfection in dentistry is always emphasized due to the serious risk of cross-contamination among the patient, clinician, and lab personnel. It has become immensely significant, especially after the COVID-19 pandemic. However, the disinfection material and process can induce changes in the physical properties of various materials used in record-making. Hence this investigation was undertaken to assess the hardness and dimensional stability of three interocclusal record materials after disinfection with iodophor. Materials and methods: Polyvinyl siloxane, Aluwax, and Zinc Oxide Eugenol (ZOE) impression paste were the materials used for this study. The material was mixed and put into a stainless steel die. The materials were divided into 3 groups with 2 subgroups having 10 samples each. The samples were subjected to immersion in 0.5% iodophor for 10 minutes. Dimensional changes and surface hardness of the samples were experimented with by traveling microscope and hardness tester respectively. Results: Polyvinylsiloxane (PVS) (Jet Bite) showed the least change in terms of dimensional stability and surface hardness when immersed in 0.5% iodophor for 10 minutes. Conclusion: Polyvinylsiloxane (Jet Bite) was found to be having considerable dimensional stability and surface hardness before and after disinfection, which was heeded by ZOE paste and Aluwax respectively.

“…One of the disadvantages of this method is the possibility of dimensional change and tearing of the impression material (Park et al, 2017 ). In this study, additional‐silicon‐based impression material was used that has an excellent dimensional stability (Lozano et al, 2021 ).…”

Objective: The purpose of this experimental in vitro study was to assess the effect of having one or two intact axial walls on the improvement of the fracture resistance, and marginal and internal adaptation of computer-aided design/computer-aided manufacturer fabricated ceramic endocrowns.Materials and Methods: Thirty-six endodontically treated mandibular molars were divided into three groups (n = 12). Group A, represented teeth that all of their axial walls were reduced till they all had 3 mm height. In group B, the buccal wall had 5 mm height and the others were reduced to 3 mm. Specimens of the group C had 5-mm-height buccal and one 5 mm-height proximal wall, with all other walls of 3 mm height. All teeth were scanned using intraoral scanner, and endocrowns were milled from zirconia lithium silicate ceramics blocks. The marginal and internal discrepancy of restorations were evaluated with the replica technique. Fracture resistance was also measured after cementation and modes of failure were observed. One-way analysis of variance and Tukey HSD multiple comparisons were used to analyze the data (α = .5).Results: Significant differences were observed within the groups in terms of the axial discrepancy (p = .022); group A had significantly higher amounts of axial discrepancy compared to group B (p = .001) and group C (p = .003). Preservation of the intact axial walls did not result in a statistically significant decrease in marginal (p = .21) and pulpal (p = .31) discrepancy values. Also, concerning the fracture resistance no significant difference was observed among the groups (p = .51). Conclusion:Preservation of at least one of the axial walls could reduce the amount of the axial discrepancy and, therefore, improves the adaptation of the restoration.However, based on this study, it did not improve fracture resistance.
